[0007] 1. The piston-type gas-powered well energy storage and power generation system has extremely low stability requirements. The powered well has low stability requirements during the dissolution process, and its stability can be controlled. Regarding the thermal decomposition of ammonium bisulfite, the requirements for heating stability are low, and heating can be done using electricity from auxiliary power generation systems such as solar energy and wind energy. It can also be combined with a thermal power plant to heat ammonium bisulfite using waste heat from the thermal power plant. Alternatively, when heating using fossil fuels such as coal, the efficiency is far higher than that of thermal power generation. Thermal power generation is limited by the Carnot cycle, and the power generation efficiency of fossil fuels is generally about 40%, but the energy conversion efficiency of the present invention can reach 90% or more. 2. In the piston-type gas-powered well energy storage and power generation system, a solution is placed at the bottom of the power well, a piston system is installed inside the power well, the power well is filled with ammonia gas and hydrogen chloride gas that are easily soluble in water, and the piston is raised. When the piston rises to its highest limit position, the gas filled inside the power well is maintained at 1 standard atmospheric pressure. Then, the rubber bag separating the solution and the gas is opened, and the gas and solution come into contact. During the process of the gas dissolving into the solution, the pressure inside the power well continuously decreases, and due to the influence of the atmospheric pressure outside the piston, the piston begins to descend. During the descent process, the gravity block is raised from a low position to a high position, and the piston reaches the lower limit of the power well. When the unit moves to its designated location, the gravity block is also hoisted up to its highest position, moves parallel to the gravity block's descending well, descends within the gravity block's well due to gravity, and further drives the generator to produce electricity.

[Modes for carrying out the invention]
[0009] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. As shown in Figures 1-16, the present invention utilizes the characteristics of ammonia gas and hydrogen chloride gas, which are extremely soluble in water and have a very large dissolution rate, to provide a power system that is not limited by resources and natural conditions. This power system aims to achieve the objective of lifting heavy objects to store energy, and then generating stable electricity using the energy stored in those heavy objects, or to generate electricity or output power directly using the power system.
[0010] The first aspect of the present invention is a vertical power system and power generation system that is not limited by terrain conditions. A solution is filled into the bottom of a power well, a piston system is installed inside the power well, and the power well is filled with ammonia gas and hydrogen chloride gas that are easily soluble in water, and the piston is raised. When the piston rises to its highest limit position, the gas filled inside the power well is maintained at 1 standard atmospheric pressure. Then, a rubber bag separating the solution and gas is opened, and the gas and solution come into contact. In the process of the gas dissolving into the solution, the pressure inside the power well continuously decreases, and due to the influence of the atmospheric pressure outside the piston, the piston begins to descend. In the process of descending, the gravity block is raised from a low position to a high position, and when the piston reaches the lower limit position of the power well, the gravity block is also raised to its highest position, and the gravity block is moved parallel to the gravity block's descending well, where it descends by gravity, and further drives the generator to generate electricity.
[0011] The gas dissolves in the solution, creating a pressure difference. This pressure difference lifts the gravity block, storing energy. Subsequently, the descent of the gravity block generates electrical energy, completing the process of "gas dissolving in the solution, storing energy, and generating electricity."
[0012] The second aspect of the present invention is a power system and a power generation system arranged at an inclination according to the slope of a mountain. The power well and the direct power system are basically the same in terms of internal structure and principle, but differ in that the power well is arranged along the slope according to its shape. The gravity block hoisting track coincides with the power well and is arranged along the slope, and as the piston of the power well descends, the gravity block is hoisted along the track from the bottom of the slope to the top of the slope. The gravity block is moved in parallel to the upper end of the gravity block descent track, and the gravity block descent track is arranged along the slope, similar to the gravity block hoisting track, and the gravity block slides along the gravity block descent track to the bottom of the slope, and in this process the generator is driven to generate electricity.
[0013] A third aspect of the present invention is that the power well system is positioned horizontally or along the ground, and while the power well and the vertical power system are basically the same in terms of internal structure and principle, they differ in that the power well is positioned horizontally on the ground.
[0014] The fourth aspect of this invention is that the piston of a power well drives a crankshaft via a link to rotate, and further, the power generated during the up-and-down motion of the piston is converted into torque by the crankshaft and transmitted to the outside. The entire process is similar to the process for a piston engine in an automobile, and when four power wells are connected in parallel, it is similar to the process for a four-cylinder inline engine in an automobile. The output process of the piston motion is two strokes. Taking an ammonia gas power well as an example, when the piston is located at the top of the power well, the gas filled in the power well is maintained at 1 standard atmospheric pressure. Then, the rubber bag separating the solution and the gas is opened, and the gas and solution come into contact. In the process of the gas dissolving into the solution, the pressure inside the power well continuously decreases, and due to the influence of the atmospheric pressure outside the piston, the piston begins to descend, driving the crankshaft via the link to rotate. The tensile force generated when the piston descends is transmitted to the crankshaft via the link, driving it to rotate, forming torque, which is then transmitted to the outside. At this point, the power well completes its first stroke. When the piston reaches its lowest position, the well is isolated from the gas by filling a rubber bag that separates the solution and gas. As the piston rises, the well is filled with ammonia gas, maintaining the gas in the powered well at 1 atmosphere during the gas filling process. When the piston reaches the top of the powered well, the powered well completes its second stroke and begins a new cycle.

[0049] The isolation device 7 is located between the sliding chamber 19 and the solution pool 20 and has an expandable end face that isolates contact between the gas in the sliding chamber 19 and the liquid in the solution pool 20.
[0050] The output shaft of the power generation equipment 5 is connected to one end of the crankshaft 36.
[0051] As shown in Figure 13, the multiple gas-powered wells are arranged linearly along the axial direction of the crankshaft 36, and the connecting frames 62 of the piston assemblies 6 in each gas-powered well are all connected to the crankshaft 36 via links 35.
[0052] Underground vertical ammonia gas powered well system
[0053] The underground vertical ammonia gas powered well system consists of a well casing, a bottom solution pool, a surface aeration and dissolution auxiliary fan well, a surface aeration and dissolution auxiliary pipe, a surface isolation rubber bag, a piston, truss columns and truss beams at the top of the powered well, a pulley, a motor, an ammonia gas injection pipe, an inlet pipe, an outlet pipe, and so on.
[0054] (1) Izutsu The well casing utilizes a circular structure with favorable stress conditions. The stress structure is made of reinforced concrete, and the inner surface is lined with a smooth, flat fiber-reinforced plastic, stainless steel, or resin that is resistant to corrosion by ammonium chloride solution, aqueous ammonia solution, hydrochloric acid, ammonia gas, and hydrogen chloride gas.
[0055] At the bottom of the well casing, the lowest position for piston operation is designed, and a piston limiting block is provided in the well wall to restrict the piston from continuing to descend.
[0056] (2) Bottom solution pool A certain depth of ammonium chloride solution is placed at the bottom of the powered well, forming a solution pool at the bottom of the well casing.
[0057] (3) Water surface aeration dissolution auxiliary fan well A fan is installed at the center of the wellhead plate to accelerate the dissolution of gas into the solution. A steel pipe is installed in the wellhead plate, extending above the water surface, and a motor is installed inside the steel pipe to drive an upper fan to rotate and blow the gas into the vent pipes at the solution surface. A gas shutoff plate is installed between the motor and the fan and at the bottom of the vent pipes, so that the air blown down from the fan is redirected by 90 degrees and enters each vent pipe. The motor cable conduit may be pre-embedded in the concrete of the wellhead base and side walls.
[0058] (4) Water surface aeration dissolution auxiliary pipe Radial vent pipes are installed at 45° intervals around the aeration and dissolution auxiliary fan well and connected to the fan well. Two annular vent pipes are provided in the radial pipes, connecting the points near the ends and near the midpoint of the radial pipes to promote the flow of gas from the fan well through the aeration and dissolution auxiliary pipes.
[0059] An open-cell sponge foam is wrapped around the vent tube, and several diffusers are formed at the top and bottom of the vent tube to rapidly diffuse the gas inside the vent tube into the open-cell sponge foam wrapped around it. The gas comes into sufficient contact with the water within the sponge foam and dissolves in the solution.
[0060] (5) Water surface isolation rubber bag A circular rubber bag is installed on the water surface, fixed to the outer wall of the fan well. When filled with gas, the rubber bag expands to cover the entire liquid surface, isolating the liquid surface from the ammonia gas inside the power well and preventing the ammonia gas from coming into contact with the ammonium chloride solution and dissolving into it.
[0061] If ammonia gas needs to dissolve in the solution, the gas inside the rubber bag is released, causing the bag to contract towards the wall of the fan well and expose the liquid surface.
[0062] (6) Piston A piston is a component that moves up and down within a well cylinder in response to changes in the pressure of the gas inside the cylinder, and is similar to the piston in an internal combustion engine.
[0063] To reduce the piston's weight and improve its overall rigidity, the piston utilizes a planar truss structure and a vertical truss structure made of lightweight steel. The piston is circular, and a stainless steel plate is provided at the bottom of the piston's planar truss to isolate it from the outside air.
[0064] The contact point between the piston and the well casing is a rigid side wall of a certain height, with rollers provided at the upper and lower ends of the side wall. These rollers provide support between the piston and the well casing wall, reducing the frictional force between the piston and the well wall during piston operation.
[0065] Between the support rollers at the upper and lower ends of the piston's side wall are two piston gas sealing rings, similar to the gas ring and oil ring in an internal combustion engine piston. Inside the piston's side wall is a water tank, which contains water. A water filler hole is formed at the top of the water tank, allowing water to be replenished through the filler hole if the water level becomes low. A connecting pipe is provided between the water tank and the two gas rings, allowing water to fill the space between the two sealing rings and form a water ring. During the piston's movement, the water ring completely isolates the ammonia gas inside the well from the outside atmosphere, preventing ammonia gas from leaking into the outside atmosphere. During the piston's movement, the water ring also provides lubrication, reducing friction between the piston ring and the well wall.
[0066] A buckle for connecting a wire rope is provided at the top of the piston's vertical truss, and the wire rope is connected to it.
[0067] (7) Truss columns and truss beams, pulleys, and motors in the upper part of the power well. Truss columns and truss beams are installed above the power well, and the truss beams are supported by the truss columns.
[0068] A pulley is installed on the truss beam, and a wire rope is wound around the pulley. A small motor is connected to the pulley, and during the process of filling the ammonia gas well with ammonia gas, the motor drives the pulley to rotate, winding up the piston. The winding of the piston is synchronized with the ammonia gas filling process in the well until the well is filled with ammonia gas at 1 atmosphere and the piston is wound up to its upper limit. When the piston descends, the pulley is disconnected from the small motor.
[0069] (8) Ammonia gas injection pipe The ammonia gas injection pipe is installed within the well wall, with its lower outlet located between the rubber bag and the piston limiting block, and its upper end connected to the ammonia gas storage tank. A valve is provided in the piping of the ammonia gas storage tank to close when ammonia gas does not need to be injected.
[0070] (9) Inlet pipe The inlet pipe is installed within the well wall, with its lower inlet located at the bottom plate of the well wall, and its upper end connected to the "ammonium chloride solution storage pool." A water pump and valve are installed at the upper end of the piping, and these are opened when it is necessary to fill the powered well with solution.
[0071] (10) Outlet pipe The water outlet pipe is installed within the well wall, with its lower outlet located at the bottom plate of the well wall, and its upper end connected to a pool of ammonium chloride solution containing ammonia water. A water pump and valve are installed at the lower end of the piping, and the water pump and valve are opened when it is necessary to pump the solution from the powered well into the pool of ammonium chloride solution containing ammonia water.
[0072] Underground vertical hydrogen chloride gas powered well system The "underground vertical hydrogen chloride gas powered well system" and the "underground vertical ammonia gas powered well system" have the same structure, but differ in the following respects.
[0073] (1) Hydrogen chloride gas is injected into the powered well. The hydrogen chloride gas injection pipe is installed inside the well wall, with its lower outlet located between the rubber bag and the piston limiting block, and its upper end connected to a hydrogen chloride gas storage tank. A valve is provided on the piping of the hydrogen chloride gas storage tank, and the valve is closed when it is not necessary to inject hydrogen chloride gas.
[0074] (2) Inlet pipe The inlet pipe is installed within the well wall, with its lower inlet located at the bottom plate of the well wall, and its upper end connected to the "ammonium chloride solution storage pool."

[0075] (3) Outlet pipe The water outlet pipe is installed within the well wall, with its lower outlet located at the bottom plate of the well wall, and its upper end connected to a pool of ammonium chloride solution containing hydrochloric acid. A water pump and valve are installed at the lower end of the piping, and the water pump and valve are opened when it is necessary to pump the solution from the powered well into the pool of ammonium chloride solution containing hydrochloric acid.

[0077] A gravity block is a heavy object made of reinforced concrete or a steel plate housing filled with concrete. Two pairs of wheels are provided on the bottom of the gravity block, and the wheels utilize the shape of train wheels and are fixed to the gravity block via brackets.
[0078] Each surface surrounding the gravity block is equipped with a pair of upper and lower positioning rollers. During the hoisting and lowering processes of the gravity block, the rollers act as a limiting force within the well, preventing the gravity block from oscillating and reducing the frictional force when the rollers come into contact with the well wall.
[0079] A suspension ring is provided in the center of the top surface of the gravity block, the bottom of which is fixed to the gravity block, and the suspension ring is connected to a wire rope.

The suspension rings at the top of the vertical truss of the powered well's piston and the top of the gravity block are connected via wire ropes, which are then wrapped around pulleys at the top of the powered well and the top of the gravity block hoisting well, respectively.
[0081] The gravity block hoisting well is a reinforced concrete structure, with an internal shape and dimensions slightly larger than the gravity block, maintaining a small gap between the well wall and the gravity block positioning roller.

[0084] A movable and retractable track is provided at the top of the gravity block hoisting well. During the process of hoisting the gravity block, the track is located on the side of the gravity block hoisting well. When the gravity block is hoisted above the wellhead, the track is moved from the side to above the wellhead, aligning with the wheels at the bottom of the gravity block. At this point, the gravity block descends slightly, and the wheels are placed on the track. The track connects to a ground track on the right side of the gravity block hoisting well. The gravity block then moves from the track to the top of the gravity block descending well.
[0085] Underground gravity block descending well system The gravity block descending well is positioned parallel to the gravity block hoisting well.

The wire rope is connected to a suspension ring at the top of the gravity block, wound around the pulley in the middle of the truss column, and the other end is wound onto a wire rope drum of the generator system.
[0090] A movable and retractable orbit is provided at the top of the gravity block descent well. The orbit is retracted before the gravity block descends, allowing the gravity block to descend along the gravity block descent well.
[0091] The gravity block descends along the descending well, and during the descent, the wire rope wound onto the wire rope drum of the generator system drives the generator to rotate and generate electricity.
[0092] Tunnel connection system The gravity block hoisting well and the gravity block descending well are connected at their bottoms via a tunnel, with a track provided on the bottom plate of the tunnel. The gravity block at the bottom of the gravity block descending well moves into the gravity block hoisting well via the tunnel and the track on the bottom plate of the tunnel.
[0093] A gravity block is located at the bottom of a gravity block hoisting well → the gravity block is hoisted up to the wellhead → it is moved along a ground orbit to the wellhead of a gravity block descending well → it descends to the bottom of the well → it is moved through a tunnel to the bottom of the gravity block hoisting well, completing one cycle.
[0094] Power generation system The power generation system is located on the side of the gravity block descending well. During the descent process, the gravity block rotates a generator using a wire rope wound onto the power generation system's wire rope drum, thereby generating electricity.
[0095] The generator system consists of a base plate, wire rope drum, variable speed gearbox, and generator.
[0096] Rail transport system The gravity block hoisting wells and gravity block descending wells connected in parallel to the ammonia gas powered well, and the gravity block hoisting well connected in parallel to the hydrogen chloride gas powered well, are connected on the ground via tracks laid on the ground and underground via tracks laid on the bottom plate of the tunnel. The tracks at the top of the gravity block hoisting wells and gravity block descending wells are openable and closable. The tracks utilize train tracks.
[0097] The gravity block completes the circulating transport process via the orbital system.
[0098] Ammonia gas storage system Next to the ammonia gas power well, a finished steel ammonia gas storage tank is installed, with a lining made of fiber-reinforced plastic, stainless steel, or resin that is resistant to corrosion from ammonia gas and hydrogen chloride gas. The ammonia gas storage capacity of the ammonia gas storage tank may be 2 to 3 times the amount of ammonia gas required for one cycle of the ammonia gas power well, and the pressure inside the tank is 1 to 2 times standard atmospheric pressure, which can satisfy the stability and guarantee rate of gas supply to the ammonia gas power well.
[0099] The ammonia gas / hydrogen chloride gas regeneration system is connected to an ammonia gas storage tank via piping and supplies ammonia gas to the storage tank intermittently or continuously.
[0100] Hydrogen chloride gas storage system Adjacent to the hydrogen chloride gas power well, a hydrogen chloride gas storage tank, a finished steel tank, is installed. The lining is made of fiber-reinforced plastic, stainless steel, or resin, which is not corroded by ammonia gas or hydrogen chloride gas. The hydrogen chloride gas storage capacity of the hydrogen chloride gas storage tank may be 2 to 3 times the amount of hydrogen chloride gas required for one cycle of the hydrogen chloride gas power well, and the pressure inside the tank is 1 to 2 times standard atmospheric pressure, which can satisfy the stability and guarantee rate of gas supply to the hydrogen chloride gas power well.
[0101] The ammonia gas / hydrogen chloride gas regeneration system is connected to a hydrogen chloride gas storage tank via piping and supplies hydrogen chloride gas to the hydrogen chloride gas storage tank intermittently or continuously.
[0102] Ammonia water-containing ammonium chloride solution pool system The solution pool utilizes a circular structure with favorable stress conditions.

[0111] The solution mixing pool is funnel-shaped, the stress structure is made of reinforced concrete, and the inner surface is lined with fiber-reinforced plastic, stainless steel, resin, etc., which are not corroded by ammonium chloride solution, aqueous ammonia solution, hydrochloric acid, ammonia gas, and hydrogen chloride gas.
[0112] The solutions in the "ammonium chloride solution pool containing ammonia water" on the left and the solutions in the "ammonium chloride solution pool containing hydrochloric acid" on the right are each combined via piping in a ratio that allows the ammonia water and hydrochloric acid to react completely into the solution mixing pool. In the mixing pool, the two solutions undergo a chemical reaction to produce a supersaturated ammonium chloride solution, and the ammonium chloride crystallizes in the pool and precipitates at the bottom of the funnel.
[0113] The bottom of the funnel has a hinged door that can be opened upward and is always open. Once the precipitated ammonium chloride fills the centrifugal drum, the hinged door at the bottom of the funnel is closed. The motor gears and the outer ring gears of the centrifugal drum are coupled to drive and rotate the centrifugal drum, centrifuging the ammonium chloride solution into the ammonium chloride solution recovery cylinder outside the centrifugal drum. After the dewatering process is complete, the dewatered ammonium chloride solid is present inside the centrifugal drum. Once the dewatering process is complete, a hinged door that can be opened downward at the bottom of the centrifugal drum is opened to discharge the ammonium chloride solid from inside the centrifugal drum and place it into the ammonium chloride solid transport car below.
[0114] During the dehydration process, the ammonium chloride solution in the ammonium chloride solution recovery cylinder is recovered into the upper solution mixing pool via piping and a piping pump installed in the piping.

[0119] The mountain-side ammonia gas (hydrogen chloride gas) powered well system is fundamentally the same structure as the underground vertical ammonia gas (hydrogen chloride gas) powered well system overall, but differs in that the bottom solution pool is arranged horizontally, the powered well is arranged at an incline along the mountain, and there is a bend between the two that is the same angle as the slope of the mountain.
[0120] The facilities related to the ammonia gas (hydrogen chloride gas) power well, such as the "ammonia gas storage tank," the "ammonium chloride solution pool containing ammonia water," the "mixed pool containing ammonia aqueous solution, ammonia aqueous solution, and hydrogen chloride solution (ammonium chloride solution pool, ammonium chloride crystal precipitate pool)," the "ammonium chloride solution pool containing hydrochloric acid," and the "ammonium chloride solution storage pool," are all located on the gentle slope at the bottom of the incline.

[0125] On the slope, a track is provided along the slope, a gate-shaped truss is provided at the top of the slope above the track, a pulley is provided at the top of the truss, one end of the wire rope is connected to a suspension ring at the top of the gravity block and is wound around the pulley at the top of the gate-shaped truss, and the other end of the wire rope passes through the pulley at the top of the gate-shaped truss and is wound onto the wire rope drum of the generator system.
[0126] As the gravity block slides along the sloped track, the wire rope drives the generator's wire rope drum and generator to rotate, completing the power generation process.

[0131] Horizontal ammonia gas (hydrogen chloride gas) powered well system Ammonia gas (hydrogen chloride gas) powered wells can be installed horizontally, which can significantly reduce construction costs.
[0132] While the horizontal ammonia gas (hydrogen chloride gas) powered well system is fundamentally the same structure as the underground vertical ammonia gas (hydrogen chloride gas) powered well system, it differs in that the bottom solution pool is positioned vertically to the ground, while the powered well is positioned parallel to the ground, forming a 90-degree angle between the two.
[0133] The following facilities related to ammonia gas (hydrogen chloride gas) powered wells are located on the ground: "ammonia gas storage tank," "ammonium chloride solution pool containing ammonia water," "mixing pool containing aqueous ammonia solution and hydrogen chloride solution (ammonium chloride solution pool, ammonium chloride crystal precipitate pool)," "ammonium chloride solution pool containing hydrochloric acid," and "ammonium chloride solution storage pool."

Furthermore, the crankshaft converts the power from the piston's up-and-down motion into torque, which is then transmitted to the outside.
[0138] (3) Parallel connection of power wells Multiple power wells may be connected in parallel to the same crankshaft, similar to an engine in a car. When four power wells are connected in parallel, it resembles a four-cylinder inline engine in a car.
[0139] Ammonia gas / hydrogen chloride gas regeneration system The ammonia gas / hydrogen chloride gas regeneration system consists of a reaction tank, an ammonia gas storage tank, a hydrogen chloride gas storage tank, and other components.
[0140] The ammonium chloride solid collected in the "ammonium chloride crystal precipitation pool" is transported to a reaction tank, where a chemical reaction occurs to produce ammonia gas and hydrogen chloride gas.
[0141] In the reaction tank, ammonium chloride reacts with sulfuric acid to produce ammonium bisulfate and hydrogen chloride gas. The resulting hydrogen chloride gas is drawn in through piping by an air pump and sent to a hydrogen chloride gas storage tank. After the reaction between ammonium chloride and sulfuric acid in the reaction tank is complete, all of the hydrogen chloride gas produced by the reaction is also drawn in and sent to the hydrogen chloride gas storage tank. The ammonium bisulfate produced by the reaction of ammonium chloride and sulfuric acid in the reaction tank is heated, and the ammonium bisulfate decomposes into sulfuric acid and ammonia gas. The resulting ammonia gas is drawn in through piping and sent to an ammonia gas storage tank. After all of the ammonium bisulfate has decomposed, all of the ammonia gas produced by the reaction is also drawn in and sent to the ammonia gas storage tank. At this point, the reaction tank returns to its initial state containing only sulfuric acid, completing one complete cycle.
[0142] (1) Reaction tank The reaction tank is a circular steel tank, and its lining is made of fiber-reinforced plastic, stainless steel, or resin, which is resistant to corrosion from ammonia gas, hydrogen chloride gas, and sulfuric acid.
[0143] The reaction tank is filled with sulfuric acid.
[0144] An electromagnetic heating device is installed at the bottom of the reaction tank and on the side wall below the sulfuric acid level to heat the sulfuric acid and the ammonium bisulfate produced by the reaction inside the reaction tank.
[0145] At the center of the reaction tank is a rotating column for the blades. The bottom of the rotating column is fitted into a bearing that protrudes from the bottom of the reaction tank. At the center of the top of the reaction tank is a bearing fitted to the outside of the rotating column, and the rotating column is fixed and rotated by the bearings.
[0146] Stirring blades are provided at the lower part of the rotating column and below the sulfuric acid level. Multiple blades are arranged along the circumference and in multiple layers along the height of the rotating column. Resistance wires are provided inside the stirring blades, allowing the sulfuric acid and ammonium bisulfate in the reaction tank to be heated by the stirring blades.
[0147] A gear disc is mounted at the top of the rotating column, and both the gear disc and the rotating column are driven by a motor to rotate at a low speed. The motor is fixed to the top of the reaction tank.
[0148] At the top of the reaction tank, there are pipes leading to an ammonia gas storage tank and a hydrogen chloride gas storage tank. An air pump is installed in the pipes to draw in the ammonia gas and hydrogen chloride gas generated in the reaction tank and send them to the ammonia gas storage tank and the hydrogen chloride gas storage tank.
[0149] Two sets of ammonium chloride transport pipes are provided at the top of the reaction tank, and these transport pipes extend into the reaction tank. A sprayer is provided at the outlet of the transport pipes and is driven by a motor to uniformly distribute the ammonium chloride solid material into the reaction tank via the sprayer and transport pipes.
[0150] The ammonium chloride supply pipe is connected to the ammonium chloride solid collection system in the ammonium chloride crystal precipitation pool, and the connection system is airtight.
[0151] To improve the reliability of gas supply, the reaction tank may be connected to a liquid ammonia storage tank, and a high-pressure air pump may be used to transport the ammonia gas produced by the reaction to the liquid ammonia storage tank. The reaction tank may also be connected to a liquid hydrogen chloride storage tank, and a high-pressure air pump may be used to transport the hydrogen chloride gas produced by the reaction to the liquid hydrogen chloride storage tank. In the event that the reaction tank is undergoing special maintenance or other operational procedures, gas can be supplied from the liquid ammonia storage tank to the ammonia gas storage tank, and from the liquid hydrogen chloride storage tank to the hydrogen chloride gas storage tank.
[0152] To improve the system's reliability, two reaction tanks are installed and operated simultaneously. When reaction tank 1 is in the ammonia gas production process, reaction tank 2 is in the hydrogen chloride gas production process. When reaction tank 1 is in the hydrogen chloride gas production process, reaction tank 2 is in the ammonia gas production process.
[0153] (2) The ammonia gas storage tanks and hydrogen chloride gas storage tanks are as described above.
[0154] (3) Liquid ammonia storage tank It is a cylindrical steel tank, and the lining is made of fiber-reinforced plastic, stainless steel, or resin, which is not corroded by ammonia gas or hydrogen chloride gas.
[0155] When a liquid ammonia storage tank is filled with liquid ammonia, the pressure is 1.1 MPa or higher, and the temperature is kept at room temperature, the ammonia inside the tank remains in a liquid state.
[0156] If it is necessary to supply gas from a liquid ammonia storage tank to an ammonia gas storage tank, open the valve in the connecting piping at the top of the tank to complete the gas supply process.
[0157] When it is necessary to inject ammonia gas into a storage tank, a high-pressure air pump is used to draw the ammonia gas produced in the reaction tank and send it into the storage tank, where it is continuously pressurized to liquefy the ammonia gas in the storage tank.
[0158] (3) Liquid hydrogen chloride storage tank It is a cylindrical steel tank, and the lining is made of fiber-reinforced plastic, stainless steel, or resin, which is not corroded by ammonia gas or hydrogen chloride gas.
[0159] When a liquid hydrogen chloride storage tank is filled with liquid hydrogen chloride, the pressure is 4.2 MPa or higher, and room temperature is maintained, the hydrogen chloride in the tank remains in a liquid state.
[0160] If it is necessary to supply gas from a liquid hydrogen chloride storage tank to a hydrogen chloride gas storage tank, open the valve in the connecting piping at the top of the tank to complete the gas supply process.
[0161] When it is necessary to inject hydrogen chloride gas into a storage tank, a high-pressure air pump is used to draw the hydrogen chloride gas produced in the reaction tank and send it into the storage tank, where it is continuously pressurized to liquefy the hydrogen chloride gas in the storage tank.

[0165] Example 1 consists of an ammonia gas storage tank, an ammonia gas powered well, a hydrogen chloride gas storage tank, a hydrogen chloride gas powered well, a gravity block hoisting well, a gravity block descending well, a generator system, an ammonium chloride solution pool containing ammonia water, an ammonium chloride solution pool containing ammonia hydrochloric acid, an ammonium chloride crystal precipitate pool, an ammonium chloride solution storage pool, a reaction tank, and the like.
[0166] The ammonia gas storage tank has a diameter of 20m, a height of 20m, and an internal pressure of 1-2 times atmospheric pressure (100-200 kPa), which corresponds to 6280-12560 m³ at standard atmospheric pressure. 3 The ammonia gas storage tank can store a certain amount of ammonia gas, with a storage capacity of 1.6 to 3.2 times the volume of the ammonia gas power well. One end of the ammonia gas storage tank is connected to the ammonia gas power well via piping, supplying ammonia gas to the well, and the other end is connected to the #1 and #2 reaction tanks via piping, supplying ammonia gas to the ammonia gas storage tank via the reaction tanks.
[0167] The hydrogen chloride gas storage tank has a diameter of 20m, a height of 20m, and an internal pressure of 1 to 2 times atmospheric pressure, which is 6280 to 12560 m³ at standard atmospheric pressure. 3 The hydrogen chloride gas storage tank can store hydrogen chloride gas, with a storage capacity of 1.6 to 3.2 times the volume of the hydrogen chloride gas power well. One end of the hydrogen chloride gas storage tank is connected to the hydrogen chloride gas power well via piping, supplying hydrogen chloride gas to the well, and the other end is connected to the #1 and #2 reaction tanks via piping, supplying hydrogen chloride gas to the hydrogen chloride gas storage tank via the reaction tanks.
[0168] The ammonia gas power well has an inner diameter of 10 m, a depth of ammonium chloride solution at the bottom of 10 m, the ammonium chloride solution serving as the mother liquor for dissolving ammonia gas, and its volume sufficient to meet the total dissolution requirement for the amount of ammonia gas needed for one day of operation of the power well, a piston stroke of 50 m, a piston diameter of 10 m, and a power well volume of 3925 m³ within the piston stroke range. 3 Therefore, when the power well is under vacuum, the external atmospheric pressure acting on the piston is 809 tons. Considering the operating efficiency and the fact that the power well cannot reach a complete vacuum during operation, if the vacuum level in the power well is 70%, the pressure difference between the internal and external gases acting on the piston is 809 × 70% = 566 tons. This is taken as the standard value for the weight of the gravity block hoisted by the power well, i.e., the weight of the gravity block is 566 tons (for the sake of explanation, the weight of the piston system itself is ignored).
[0169] The parameters for a hydrogen chloride gas powered well are the same as those for an ammonia gas powered well.
[0170] The gravity block is made of reinforced concrete and has dimensions of 5.5 x 5.5 x 7.5 m (length x width x height), with a weight of 566 tons.
[0171] The gravity block hoisting well is a rectangular well with internal dimensions of 6.0 x 6.0 m and a depth of 57.5 m.
[0172] The gravity block descending well is a rectangular well with internal dimensions of 6.0 × 6.0 m and a depth of 57.5 m.
[0173] The ammonium chloride solution pool containing ammonia water has a diameter of 14m and a depth of 11m.
[0174] The pool of ammonium chloride solution containing hydrochloric acid has a diameter of 14m and a depth of 11m.
[0175] The mixed pool containing an aqueous ammonia solution, an aqueous ammonia solution, and a hydrogen chloride solution (ammonium chloride solution pool, ammonium chloride crystal precipitate pool) has a diameter of 20m, a side wall depth of 11m, a funnel at its bottom, and a centrifugal drum at the bottom of the funnel for recovering solid ammonium chloride, with a diameter of 4m.
[0176] The ammonium chloride solution storage pool has a diameter of 14m and a depth of 11m.
[0177] Initial system state: The power well is filled with ammonium chloride solution at the design level, the piston is at the highest limit position of the power well, the gas-filled rubber bag in the power well is inflated by gas filling, the power well is filled with ammonia gas at standard atmospheric pressure, the ammonium chloride solution storage pool is full capacity, and the gravity block is located at the bottom of the gravity block hoisting well.
[0178] When the gas is released from the gas-filled rubber bag, the bag shrinks from covering the entire water surface to the well wall of the fan well.
[0179] As the solution surface comes into contact with the ammonia gas in the well, the ammonia gas dissolves in the ammonium chloride solution. As the ammonia gas dissolves in the ammonium chloride solution, the pressure in the well decreases, causing the piston to begin descending. The wire rope and pulley system then hoists up the gravity block of the gravity block hoisting well. When the piston reaches the lower limit block of the powered well, the gravity block is hoisted up to the wellhead of the gravity block hoisting well. The movable track at the wellhead of the gravity block hoisting well is moved to the bottom of the gravity block and aligned with the gravity block's wheels. The gravity block travels along the wellhead track and the track laid between the gravity block hoisting well and the gravity block descending well to the wellhead of the gravity block descending well. The track at the wellhead of the gravity block descending well is moved into retraction, and the gravity block descends along the gravity block descending well. During the descent, the wire rope and pulley system drives the generator to rotate and generate electricity. Regarding gravity blocks, after descending to the bottom of the well, they are hoisted up along the tunnel and moved back to the bottom of the well, returning to their initial state, and the next cycle begins.
[0180] As the gravity block descends and generates electricity, the gas-filled rubber bag of the ammonia gas power well is filled with gas and expands, isolating the liquid surface from the gas inside the power well. A motor on the truss pulley at the wellhead winds up the piston, and as the piston rises, the ammonia gas storage tank fills the ammonia gas power well with gas. When the piston reaches the top, the ammonia gas inside the ammonia gas power well is at standard atmospheric pressure. At this point, the ammonia gas power well is in its initial state, and the next cycle begins.
[0181] An ammonia gas powered well completes one cycle every 12 minutes, five cycles every hour, and assuming 22 hours of operation per day, it will complete 110 cycles.
[0182] During operation, the dissolution rate of ammonia gas can be further accelerated by a dissolution-assisting fan, allowing for an increase in the number of cycles.
[0183] The circulation cycle of the ammonium chloride solution in the ammonia gas-powered well is 1 day, and the solution exchange time is 2 hours.
[0184] In ammonia gas-powered wells, the ammonia gas dissolution rate slows down as the ammonia concentration in the solution increases. If the natural dissolution rate does not meet the requirements, a surface aeration dissolution auxiliary fan can be activated to blow ammonia gas into the surface aeration dissolution auxiliary pipe, accelerating the ammonia gas dissolution process and shortening the circulation time.
[0185] Hydrogen chloride powered wells and ammonia gas powered wells operate in the same way, but they differ in that one generates power by dissolving ammonia gas in an ammonium chloride solution to create a vacuum, while the other generates power by dissolving hydrogen chloride gas in an ammonium chloride solution to create a vacuum.
[0186] One ammonia gas powered well and one hydrogen chloride powered well simultaneously power a single gravity block descending well power generation system. The descent speed of the gravity block is adjusted to synchronize the well's circulation cycle with the power generation rate, completing the system's continuous operation.
[0187] To improve the reliability of system operation, some gravity blocks may be pre-placed on the ground.
[0188] By staggering the solution exchange times for ammonia gas-powered wells and hydrogen chloride gas-powered wells, and setting the solution exchange times to coincide with dips in electricity demand, it is possible to ensure uninterrupted power generation during system operation.
[0189] Alternatively, multiple such systems can be connected in parallel, and the solution exchange times for each system can be staggered to achieve uninterrupted power generation.
[0190] When exchanging the solution in an ammonia gas powered well, the solution is pumped into an ammonium chloride solution pool containing ammonia water, and then saturated ammonium chloride solution, which has been stored in an ammonium chloride solution storage pool, is injected into the ammonia gas powered well to complete the solution exchange.
[0191] When exchanging the solution in a hydrogen chloride gas-powered well, the solution is pumped into a pool of ammonium chloride solution containing hydrochloric acid, and then saturated ammonium chloride solution, which has been stored in an ammonium chloride solution storage tank, is injected into the hydrogen chloride gas-powered well to complete the solution exchange.
[0192] The pumping process in an ammonia gas-powered well can be synchronized with the water injection process in a hydrogen chloride gas-powered well, and vice versa. In this way, the energy generated by water injection can be used for pumping, saving energy consumption for solution exchange.
[0193] To measure the ammonia content in a solution within an ammonium chloride solution pool containing ammonia water, and to measure the hydrochloric acid content in a solution within an ammonium chloride solution pool containing hydrochloric acid, the solutions from each solution pool are injected into a mixed pool containing ammonia aqueous solution, ammonia aqueous solution, and hydrogen chloride solution (ammonium chloride solution pool, ammonium chloride crystal precipitate pool) in proportion to the ratios at which they can react completely with each other. The ammonia and hydrogen chloride in the mixture in the pool chemically react to produce ammonium chloride, the ammonium chloride solution becomes supersaturated, and the ammonium chloride crystallizes and precipitates in the pool. The solid ammonium chloride is then separated and collected by a centrifugal drum at the bottom of the pool. The operating cycle required to complete this system is one day, which is the same as the solution exchange cycle for a powered well.
[0194] The collected ammonium chloride solid is transported to reaction tanks 1 and 2, where the production of ammonia gas and hydrogen chloride gas is completed in the ammonia gas / hydrogen chloride gas regeneration system. The solid is then transported to the ammonia gas (hydrogen chloride gas) storage tank, completing the ammonia gas and hydrogen chloride gas recycling process.
[0195] The reaction cycle of the reaction tank is 1 day, which is the same as the operating cycle of the ammonium chloride crystal precipitation pool. In other words, the ammonium chloride crystal precipitation pool can process all the solutions exchanged in the ammonia gas powered well and the hydrogen chloride gas powered well in 1 day, and transport the generated and collected ammonium chloride solids to the ammonia gas / hydrogen chloride gas regeneration system one after another.
[0196] In the ammonia gas / hydrogen chloride gas regeneration system's reaction tank, the process of generating ammonia gas takes 11 hours, and the process of generating hydrogen chloride gas also takes 11 hours, for a total of 22 hours, which matches the operating time of the power well system. Reaction tanks 1 and 2 operate alternately; that is, when reaction tank 1 generates ammonia gas, reaction tank 2 generates hydrogen chloride gas, and when reaction tank 2 generates ammonia gas, reaction tank 1 generates hydrogen chloride gas. In this way, the ammonia gas / hydrogen chloride gas regeneration system operates in sync with the power well system, supplies gas synchronously, improves the guarantee rate of gas supply, and reduces energy consumption during the gas storage process.
[0197] If the mass of the gravity block hoisted by the powered well is 566 tons, the hoisting height is 50 m, the gravitational potential energy stored in one hoisting cycle is 277,332,650 joules, and the generator efficiency is 95%, then the gravitational potential energy stored in one hoisting cycle is converted into 73 kWh of electrical energy. If the number of cycles for one powered well is 110 per day, the power generation of one powered well is 8050 degrees per day. Since the above system set has one ammonia gas powered well and one hydrogen chloride gas powered well, the power generation of the above system set is 16100 degrees per day. The annual power generation is 5.88 million degrees.
[0198] During the operation of the above system, the energy consumption required for solution exchange in the power wells, and for gas transport between the reaction tank and the gas storage tank, and between the gas storage tank and the power wells, is almost negligible. The greatest energy demand is the reaction heat required to decompose the ammonium bisulfate in the reaction tank by heating it to approximately 200°C during the process of generating ammonia gas in the reaction tank.
[0199] Example 2 Example 2 is a power system and power generation system that can significantly reduce investment based on the conditions of slopes along mountains when mountainous terrain conditions are present.
[0200] Example 2 describes a case where the elevation difference of the mountain slope is 100m and the gradient is 1:1. In actual construction, the slope track system can be positioned along the slope in accordance with changes in the slope's gradient and is not limited to a single gradient.
[0201] Example 2 consists of an ammonia gas storage tank, an ammonia gas power well, a hydrogen chloride gas storage tank, a hydrogen chloride gas power well, a gravity block hoisting orbit, a gravity block descent orbit, a generator system, an ammonium chloride solution pool containing ammonia water, an ammonium chloride solution pool containing ammonia hydrochloric acid, an ammonium chloride crystal precipitation pool, an ammonium chloride solution storage pool, a reaction tank, and the like.
[0202] The ammonia gas storage tank has a diameter of 34m, a height of 20m, and an internal pressure of 1-2 times atmospheric pressure (100-200 kPa), which corresponds to 18150-36298 m³ at standard atmospheric pressure. 3 The ammonia gas storage tank can store a certain amount of ammonia gas, with a storage capacity of 1.6 to 3.2 times the volume of the ammonia gas power well. One end of the ammonia gas storage tank is connected to the ammonia gas power well via piping, supplying ammonia gas to the well. The other end is connected to the #1 and #2 reaction tanks via piping, supplying ammonia gas to the ammonia gas storage tank via the reaction tanks.
[0203] The hydrogen chloride gas storage tank has a diameter of 34m, a height of 20m, and an internal pressure of 1-2 times atmospheric pressure (100-200 kPa), which corresponds to 18150-36298 m³ at standard atmospheric pressure. 3 The hydrogen chloride gas storage tank can store a quantity of hydrogen chloride gas, with a storage capacity of 1.6 to 3.2 times the volume of the hydrogen chloride gas power well. One end of the hydrogen chloride gas storage tank is connected to the hydrogen chloride gas power well via piping, supplying hydrogen chloride gas to the well. The other end is connected to the #1 and #2 reaction tanks via piping, and the reaction tanks supply hydrogen chloride gas to the hydrogen chloride gas storage tank.
[0204] The ammonia gas power well has an inner diameter of 10 m, a depth of ammonium chloride solution at the bottom of 30 m, the ammonium chloride solution serving as the mother liquor for dissolving ammonia gas, and its volume sufficient to meet the total dissolution requirement for the amount of ammonia gas needed for one day of operation of the power well, a piston stroke of 141 m, a piston diameter of 10 m, and a volume of the power well within the piston stroke range of 11135 m³. 3Therefore, if the powered well is in a vacuum state, the external atmospheric pressure acting on the piston is 809t. Considering the operating efficiency and the fact that the powered well cannot reach a complete vacuum state during the operating process, if the vacuum level in the powered well is 70%, the pressure difference between the internal and external gases acting on the piston is 809 × 70% = 566t, and this is taken as the standard value for the hoisting capacity of the powered well (for the sake of explanation, the weight of the piston system is ignored). If the gradient of the gravity block hoisting trajectory is 1:1, the weight of the gravity block is 566 / sin(45°) = 801, that is, the weight of the gravity block is 801t.
[0205] The parameters for a hydrogen chloride gas powered well are the same as those for an ammonia gas powered well.
[0206] The gravity block is made of reinforced concrete and has dimensions of 6.84 x 6.84 x 6.84 m (length x width x height), with a weight of 801 tons.
[0207] The gravity block hoisting track, gravity block sliding track, slope bottom ground track, and slope top ground track utilize the train's tracks, and the lower part of the gravity block is equipped with two pairs of wheels corresponding to the tracks, which also utilize the train's wheels.
[0208] The ammonium chloride solution pool containing ammonia water has a diameter of 17m and a depth of 20m.
[0209] The pool of ammonium chloride solution containing hydrochloric acid has a diameter of 17m and a depth of 20m.
[0210] The mixed pool containing ammonia aqueous solution and hydrogen chloride solution (ammonium chloride solution pool, ammonium chloride crystal precipitate pool) has a diameter of 20m, a side wall depth of 20m, and a funnel at its bottom. The bottom of the funnel is a centrifugal drum for recovering solid ammonium chloride, and the centrifugal drum has a diameter of 4m.
[0211] The ammonium chloride solution storage pool has a diameter of 17m and a depth of 20m.
[0212] Initial system state: The power well is filled with ammonium chloride solution at the design level, the piston is at the highest limit position of the power well, the gas-filled rubber bag in the power well is inflated by gas filling, the power well is filled with ammonia gas at standard atmospheric pressure, the ammonium chloride solution storage pool is full capacity, and the gravity block is located at the bottom of the gravity block winding orbit.
[0213] When the gas is released from the gas-filled rubber bag, the bag shrinks from covering the entire water surface to the well wall of the fan well.
[0214] As the solution surface comes into contact with the ammonia gas in the well, the ammonia gas dissolves in the ammonium chloride solution. As the ammonia gas dissolves in the ammonium chloride solution, the pressure in the well decreases, causing the piston to begin descending. The wire rope and pulley system hoists the gravity block along the gravity block hoisting track from the bottom of the slope to the top of the slope. When the piston has acted down to the lower limit block of the power well, the gravity block is hoisted up to the top of the slope. When the gravity block reaches the top of the slope platform, the track in which the gravity block is located rotates 90 degrees and connects to the top of the slope ground track. The gravity block moves along the top of the slope ground track to the top of the gravity block sliding track, where the track in which the gravity block is located rotates 90 degrees and connects to the gravity block sliding track. The gravity block slides along the gravity block sliding track, and during the sliding process, the wire rope and pulley system drives and rotates the generator to generate electricity. As the gravity block slides down to the bottom platform, its trajectory rotates 90 degrees, connecting to the bottom ground trajectory. It then moves along the bottom ground trajectory to the gravity block hoisting trajectory, where it rotates 90 degrees again, connecting to the gravity block hoisting trajectory. The next cycle begins.
[0215] During the process of the gravity block sliding and generating electricity, the gas-filled rubber bag of the ammonia gas power well is filled with gas and inflated, isolating the liquid surface from the gas inside the power well. A motor on the truss pulley at the wellhead winds up the piston, and as the piston rises, the ammonia gas storage tank fills the ammonia gas power well with gas. When the piston reaches the top, the ammonia gas inside the ammonia gas power well is at standard atmospheric pressure. At this point, the ammonia gas power well is in its initial state, and the next cycle begins.
[0216] An ammonia gas powered well completes one cycle every 12 minutes, five cycles every hour, and assuming 22 hours of operation per day, it will complete 110 cycles.
[0217] During operation, the dissolution rate of ammonia gas can be further accelerated by a dissolution-assisting fan, allowing for an increase in the number of cycles.
[0218] The circulation cycle of the ammonium chloride solution in the ammonia gas-powered well is 1 day, and the solution exchange time is 2 hours.
[0219] In ammonia gas-powered wells, the ammonia gas dissolution rate slows down as the ammonia concentration in the solution increases. If the natural dissolution rate does not meet the requirements, a surface aeration dissolution auxiliary fan can be activated to blow ammonia gas into the surface aeration dissolution auxiliary pipe, accelerating the ammonia gas dissolution process and shortening the circulation time.
[0220] Hydrogen chloride powered wells and ammonia gas powered wells operate in the same way, but they differ in that one generates power by dissolving ammonia gas in an ammonium chloride solution to create a vacuum, while the other generates power by dissolving hydrogen chloride gas in an ammonium chloride solution to create a vacuum.
[0221] One ammonia gas powered well and one hydrogen chloride powered well simultaneously power a single gravity block gliding orbit power generation system. The descent speed of the gravity block is adjusted to synchronize the circulation cycle and power generation rate of the powered wells, thereby completing the system's continuous operation.
[0222] To improve the reliability of system operation, several gravity blocks may be pre-positioned at the top of the slope.
[0223] By staggering the solution exchange times for ammonia gas-powered wells and hydrogen chloride gas-powered wells, and setting the solution exchange times to coincide with dips in electricity demand, it is possible to ensure uninterrupted power generation during system operation.
[0224] Alternatively, multiple such systems can be connected in parallel, and the solution exchange times for each system can be staggered to achieve uninterrupted power generation.
[0225] When exchanging the solution in an ammonia gas powered well, the solution is pumped into an ammonium chloride solution pool containing ammonia water, and then saturated ammonium chloride solution, which has been stored in an ammonium chloride solution storage pool, is injected into the ammonia gas powered well to complete the solution exchange.
[0226] When exchanging the solution in a hydrogen chloride gas-powered well, the solution is pumped into an ammonium chloride solution pool containing hydrochloric acid, and then a saturated ammonium chloride solution, pre-stored in an ammonium chloride solution storage pool, is injected into the hydrogen chloride gas-powered well to complete the solution exchange.
[0227] The pumping process in an ammonia gas-powered well can be synchronized with the water injection process in a hydrogen chloride gas-powered well, and vice versa. In this way, the energy generated by water injection can be used for pumping, saving energy consumption for solution exchange.
[0228] To measure the ammonia content in a solution within an ammonium chloride solution pool containing ammonia water, and to measure the hydrochloric acid content in a solution within an ammonium chloride solution pool containing hydrochloric acid, the solutions from each solution pool are injected into a mixed pool containing ammonia aqueous solution, ammonia aqueous solution, and hydrogen chloride solution (ammonium chloride solution pool, ammonium chloride crystal precipitate pool) in proportion to the ratios at which they can react completely with each other. The ammonia and hydrogen chloride in the mixture in the pool chemically react to produce ammonium chloride, the ammonium chloride solution becomes supersaturated, and the ammonium chloride crystallizes and precipitates in the pool. The solid ammonium chloride is then separated and collected by a centrifugal drum at the bottom of the pool. The operating cycle required to complete this system is one day, which is the same as the solution exchange cycle for a powered well.
[0229] The collected ammonium chloride solid is transported to reaction tanks 1 and 2, where the production of ammonia gas and hydrogen chloride gas is completed in the ammonia gas / hydrogen chloride gas regeneration system. The solid is then transported to the ammonia gas (hydrogen chloride gas) storage tank, completing the ammonia gas and hydrogen chloride gas recycling process.
[0230] The reaction cycle of the reaction tank is 1 day, which is the same as the operating cycle of the ammonium chloride crystal precipitation pool. In other words, the ammonium chloride crystal precipitation pool can process all the solutions exchanged in the ammonia gas powered well and the hydrogen chloride gas powered well in 1 day, and transport the generated and collected ammonium chloride solids to the ammonia gas / hydrogen chloride gas regeneration system one after another.
[0231] In the ammonia gas / hydrogen chloride gas regeneration system, the process of generating ammonia gas in the reaction tank takes 11 hours, and the process of generating hydrogen chloride gas also takes 11 hours, for a total of 22 hours, which matches the operating time of the power well system. Reaction tanks 1# and 2# operate alternately; that is, when reaction tank 1# generates ammonia gas, reaction tank 2# generates hydrogen chloride gas, and when reaction tank 2# generates ammonia gas, reaction tank 1# generates hydrogen chloride gas. In this way, the ammonia gas / hydrogen chloride gas regeneration system operates in sync with the power well system, supplies gas synchronously, improves the guarantee rate of gas supply, and reduces energy consumption during the gas storage process.
[0232] Assuming the mass of the gravity block hoisted by the powered well is 801 tons, the hoisting height is 100 m, the gravitational potential energy stored in one hoisting cycle is 784,727,702 joules, and the generator efficiency is 95%, the gravitational potential energy stored in one hoisting cycle is converted into 207 kWh of electrical energy. If one powered well cycles 110 times per day, the power generated by one powered well is 22,800 degrees per day. Since the above system has one ammonia gas powered well and one hydrogen chloride gas powered well, the power generated by the above system is 45,560 degrees per day. The annual power generation is 5.88 million degrees.
[0233] During the operation of the above system, the energy consumption required for solution exchange in the power wells, and for gas transport between the reaction tank and the gas storage tank, and between the gas storage tank and the power wells, is almost negligible. The greatest energy demand is the reaction heat required to decompose the ammonium bisulfate in the reaction tank by heating it to approximately 200°C during the process of generating ammonia gas in the reaction tank. Example 3
[0234] Regarding the powered well in Example 1, it is necessary to construct a vertical well below ground level or to provide a complex support structure above ground level. Regarding the powered well in Example 2, it is necessary to construct it along a slope that follows a mountain, and there is a problem that construction becomes difficult if the slope is not flat.
[0235] Both Example 1 and Example 2 present the problem of difficulty in constructing powered wells and high construction costs.
[0236] As an optimization for powered wells, they can be constructed on the ground, as shown in Figure 11.
[0237] Assuming the ground is level, the portion of the power well below the gas-filled rubber bag is positioned vertically, similar to a vertical power well. The piston stroke portion of the power well is positioned horizontally along the ground, forming a 90-degree angle with the solution pool of the power well. In this configuration, the majority of the power well is located on the ground, significantly reducing the difficulty and cost of constructing the power well.
[0238] If the ground has a certain slope, the piston stroke portion of the power well is also positioned along the ground, forming an obtuse angle greater than 90 degrees or an acute angle less than 90 degrees with respect to the solution pool of the power well.
[0239] The operation process of the powered well in this embodiment is the same as that of the powered wells in Embodiments 1 and 2. Example 4
[0240] In Examples 1 and 2, the powered well hoists up the gravity block to store potential energy, and then the powered block converts the potential energy into kinetic energy, thereby completing the power generation process.
[0241] In Embodiment 4, the power of the power well is directly output by the crankshaft, which is connected to the piston of the power well, by being driven by the power well. Refer to Figures 12 and 13.
[0242] Let's explain using four ammonia gas powered wells as an example.
[0243] Four power wells are arranged in parallel, and the top of the piston of each power well is connected to the crankshaft via a link. Power wells 1# and 4# operate in the same condition as a pair, and power wells 2# and 3# also operate in the same condition as a pair.
[0244] Initial state: The pistons of powered wells #1 and #4 are at their lower limit position, and the pistons of powered wells #2 and #3 are at their upper limit position.
[0245] When gas is released from the gas-filled rubber bags in the #2 and #3 powered wells, the bags contract from covering the entire water surface to the well wall of the fan well. The ammonia gas dissolves in the ammonium chloride solution, creating negative pressure inside the well. Under atmospheric pressure, the piston descends, driving the crankshaft to rotate and outputting power to the outside. When the piston reaches its lower limit, it fills the gas-filled rubber bags in the #2 and #3 powered wells with gas, causing the bags to cover the entire water surface. As the piston rotates and moves upward, it fills the powered wells with ammonia gas, maintaining a constant pressure of 1 atmosphere throughout the gas filling process. When the piston reaches its upper limit, the ammonia gas filling pipe is closed. At this point, one complete process is finished, and the next cycle begins.
[0246] Gas is filled into the gas-filled rubber bags of powered wells #1 and #4, so that the rubber bags cover the entire water surface. As the piston rotates and is driven upward, ammonia gas is filled into the powered wells. During the gas filling process, the ammonia gas in the powered wells is always maintained at 1 atmosphere. When the piston has moved to its upper limit position, the ammonia gas filling pipe is closed, and the gas is released from the gas-filled rubber bags of powered wells #1 and #4, causing the rubber bags to contract from covering the entire water surface to the well wall of the fan well. The ammonia gas dissolves in the ammonium chloride solution, creating negative pressure in the well. Under atmospheric pressure, the piston descends until it moves to its lower limit position, driving the crankshaft to rotate and outputting power to the outside. At this point, one complete process is finished, and the next cycle begins.
[0247] The operation processes of the 1# and 4# power wells and the 2# and 3# power wells are synchronized.
[0248] In the process of the piston descending, the dissolution auxiliary fan can accelerate and control the descending speed of the piston.
[0249] Similar to the above embodiment, by combining the power well with the ammonia gas - hydrogen chloride gas regeneration system, each power well can be continuously operated.
[0250] The power operation process of this embodiment is similar to the operation process of the piston of an internal combustion engine. The internal combustion engine belongs to a heat engine, has a small cylinder volume, a high rotational speed, and does work by gas expansion. However, this embodiment does not belong to a heat engine, has a large cylinder volume, a low rotational speed, and generates negative pressure and does work by the gas dissolving in the solution and contracting. [[ID=H16]]
[0251] This embodiment may be used for direct power generation or may be used on large ships to directly drive the ship's transmission system. It may also be used in other power fields such as mines and machinery.
[0252] Example 5 It is an ammonia gas - hydrogen chloride gas regeneration system.
[0253] It is composed of two reaction tanks and attached liquid ammonia storage tanks, liquid hydrogen chloride storage tanks, ammonia gas storage tanks, and hydrogen chloride gas storage tanks. Refer to FIGS. 15, FIGS. 16, and FIGS. 17.
[0254] The liquid ammonia storage tank and the liquid hydrogen chloride storage tank are cylindrical steel tanks, and the lining is a lining such as fiber-reinforced plastic, stainless steel, resin, etc. that is not corroded by ammonia gas and hydrogen chloride gas. The liquid ammonia storage tank and the liquid hydrogen chloride storage tank are for improving the guarantee rate of ammonia gas and hydrogen chloride gas in the power well system, and are not essential equipment of the system. The volume size and the necessity of installation can be determined according to the requirements of the system.
[0255] The ammonia gas storage tank and the hydrogen chloride gas storage tank are a transition system connecting the reaction tank and the power well, temporarily storing the ammonia gas and hydrogen chloride gas generated in the reaction tank in the tank. In order to improve the guarantee rate of the gas supply of the system, the pressure of the storage tank may be 100-200 KPa. In the ascending process of the piston of the power well, the storage tank plays a role in connecting the reaction tank and the power well. In the descending process of the piston of the power well, there is no need to supply gas to the power well. At this time, the gas produced in the reaction tank is temporarily stored in the storage tank.
[0256] The chemical reaction process in the reaction tank: Sulfuric acid exists in the reaction tank, and ammonium chloride solid generated in the ammonium chloride crystal precipitation pool in the power well system reacts with sulfuric acid in the reaction tank to generate ammonium bisulfate and hydrogen chloride gas. The chemical reaction equation is H4Cl + H2SO4 === NH4HSO4 + HCl↑. The generated hydrogen chloride gas is transported to the hydrogen chloride gas storage tank through the pipeline. What remains in the reaction tank is ammonium bisulfite. Ammonium bisulfate is heated to about 200 °C and thermally decomposed into ammonia gas and sulfuric acid. The generated ammonia gas is transported to the ammonia gas storage tank through the pipeline. After the reaction is completed, what remains in the reaction tank is sulfuric acid, and it returns to the initial state of the reaction tank.
[0257] Taking Example 1 as an example.
[0258] With two reaction tanks forming a set, the processing capacity of one set of reaction tanks must meet the amount of ammonium chloride produced per day by one ammonia gas powered well and one hydrogen chloride powered well system.
[0259] The daily ammonia gas consumption of the ammonia gas powered well is 334 tons, and the daily hydrogen chloride gas consumption of the hydrogen chloride powered well is 640 tons. If the total weight of ammonium chloride produced by the entire system per day is 974 tons, then the amount of ammonium chloride processed in one reaction tank is 974 / 2 = 487 tons. For one reaction tank, the time it takes to produce ammonia gas is the same as the time it takes to produce hydrogen chloride gas, corresponding to the operating time of the power system. That is, for one reaction tank, the time it takes to produce ammonia gas is 11 hours, and the time it takes to produce hydrogen chloride gas is 11 hours. The two reaction tanks operate alternately; when reaction tank 1 produces ammonia gas, reaction tank 2 produces hydrogen chloride gas.
[0260] Since one reaction tank needs to process 487 tons of ammonium chloride, a minimum of 891 tons of sulfuric acid must be present in the reaction tank to meet the demand for reaction with ammonium chloride.
[0261] The reaction tank has a diameter of 10m, and as a conservative design, 1000 tons of sulfuric acid are pre-filled into the reaction tank, with a bulk density of 1840 kg / m³. 3 The depth of the sulfuric acid solution in the reaction tank is 6.9 m.
[0262] When 487 tons of ammonium chloride react with sulfuric acid in the reaction tank, the weight of the ammonium bisulfate produced is 1225 tons, the bulk density of the ammonium bisulfate is 1780 kg / m³, and the depth of the ammonium bisulfate in the reaction tank is 8.8 m.
[0263] The reaction tank is 20 meters high to leave sufficient space for the chemical reaction and some space for gas storage.
[0264] Initial state of the two reaction tanks: Each tank is filled with 1000 tons of sulfuric acid.
[0265] 1. Reaction Tank: 487 tons of ammonium chloride are introduced into the reaction tank at a rate of 0.74 tons / minute via an ammonium chloride supply pipe and sprayer located at the top of the reaction tank. The introduced ammonium chloride chemically reacts with sulfuric acid in the reaction tank to produce hydrogen chloride gas and ammonium bisulfate. The generated hydrogen chloride gas is transported to the hydrogen chloride gas storage tank via a hydrogen chloride gas transport pipe and air pump located at the top of the reaction tank. After 11 hours, all 487 tons of ammonium chloride have been introduced, and the reaction is complete. At this point, the substance in the reaction tank is ammonium bisulfate.
[0266] The electromagnetic heating systems in the bottom, body, and stirring blades of the reaction tank are activated to heat the ammonium bisulfate inside the reaction tank to approximately 200°C. The ammonium bisulfate inside the reaction tank is thermally decomposed into sulfuric acid and ammonia gas, and the resulting ammonia gas is transported to an ammonia gas storage tank by ammonia gas transport piping and an air pump located at the top of the reaction tank.
[0267] By controlling the decomposition rate of ammonium bisulfate through measures such as layered heating, temperature control, and intermittent heating, decomposition is achieved at a constant rate within 11 hours. For example, first, the electromagnetic heating system in the uppermost stirring blade and the electromagnetic heating system in the upper part of the tank are activated, then the electromagnetic heating systems in the stirring blade and the tank are activated layer by layer, and after all the ammonium bisulfate has decomposed, the substance remaining in the reaction tank is sulfuric acid, returning to the initial state.
[0268] When reaction tank 1 begins to generate hydrogen chloride gas, reaction tank 2 starts operating, adding ammonium chloride and initiating the process of producing ammonia gas. This alternating operation allows the two reaction tanks to simultaneously produce ammonia and hydrogen chloride gases throughout the 22-hour operation period of the power well, thereby forming a complete closed-loop regeneration and circulation system together with the power well system.
[0269] Example 6 This is a heating source system for a reaction tank.
[0270] In each of the above embodiments, the main energy consumption process is the process of heating ammonium bisulfate in the reaction tank to generate ammonia gas.
[0271] In each of the above embodiments, the operating characteristics of the system and the presence of the gas storage system result in extremely low requirements for the operational stability of the power wells and reaction tanks of the entire system.
[0272] Powered wells have low requirements for operational stability during the gas dissolution process, and can be fast or slow.
[0273] Regarding the thermal decomposition of ammonium bisulfate in the reaction tank, the requirements for the stability of the thermal decomposition process are low, it can be fast or slow, intermittent or not. Taking Example 1 as an example, when the pressure in the ammonia gas storage tank is 200 KPa, the volume of ammonia gas in the storage tank is 3.2 times the amount of ammonia gas required for one cycle of the ammonia gas power well. That is, when the reaction tank does not supply ammonia gas to the ammonia gas storage tank, the ammonia gas stored in the ammonia gas storage tank can meet three cycles of the ammonia gas power well. The time for one cycle of the ammonia gas power well is 12 minutes, and the time for three cycles is 36 minutes. That is, the reaction tank can stop for about 30 minutes during the process of producing ammonia gas. To increase the pressure of the ammonia gas in the ammonia gas storage tank or the volume of the storage tank, the requirements for the stability of the reaction tank of the system are even lower.
[0274] When ammonia gas is pressurized to 1.06 MPa at an environmental temperature of 30 °C, it changes from a gas to a liquid state. 1 m 3 of liquid ammonia can be converted into 790 m 3 of ammonia gas. Since the main energy consumption process of the system is to heat ammonium bisulfate to produce ammonia gas, and considering that ammonia gas is easy to store in a liquid state, the system can increase the storage amount of liquid ammonia and further reduce the requirements for the stability of the reaction tank to generate ammonia gas.
[0275] Taking Example 1 as an example, the daily ammonia gas consumption of the ammonia gas power well is 433,000 m 3 and the ammonia gas consumption for two days is 866,000 m 3 When the ammonia gas used by the ammonia gas power well for two days is converted into liquid ammonia, the volume of liquid ammonia becomes 1097 m 3 3 3Only the liquid ammonia storage tank can hold the amount of ammonia gas required for the ammonia gas power well to operate for two days.
[0276] From the above, to generate ammonia gas by heating ammonium bisulfate in the reaction tank, the requirements for the stability of the heat source are very low, and the power of auxiliary power generation systems such as solar energy and wind energy with unstable power generation can be used to provide a heat source for the reaction tank.
[0277] Coal can be used to directly provide thermal energy to the reaction tank. As is well known, the thermal efficiency of a general thermal power plant only reaches about 40%. When coal is used to directly provide thermal energy to the reaction tank, the utilization rate of the thermal efficiency of the coal can reach more than 90%. That is, if this power generation system is scaled up and all are used to heat the reaction tank with coal instead of a thermal power plant, the utilization rate of the thermal efficiency of the coal will be more than 90%, which is more than twice the utilization rate of the thermal efficiency of the coal in a thermal power plant.
[0278] In combination with a thermal power plant, waste heat such as the exhaust gas and steam of the thermal power plant can be utilized, and the flue gas and steam pipelines can be spirally arranged in the reaction tank to heat the ammonium bisulfate in the reaction tank and be used as the heat source of the reaction tank.
[0279] In combination with an ocean cargo ship, the exhaust gas of the large engine of the cargo ship can be used as the heat source of the reaction tank to become the auxiliary power system of the cargo ship and improve the fuel energy utilization rate of the ocean wheel.
[0280] The system can be used in a truck or a small car and may be miniaturized to be used as the power system of the vehicle.
[0281] Example 7 In the above example, the gas temperature in the power well is 20°C at room temperature, and the temperature of the gas generated in the reaction tank is not considered.
[0282] In the above embodiment, scaling up and systematizing the process allows for complete synchronization between the production process in the reaction tank and the operation process of the power well, thereby maximizing energy utilization. For example, if the temperature of the ammonia gas produced in the reaction tank is 200°C, and the reaction tank and the power well are operated synchronously, the temperature of the ammonia gas transported into the power well will also be 200°C. At standard atmospheric pressure, the density of ammonia gas at 20°C is 0.759 kg / m³. 3 Therefore, its density at 200℃ is 0.438 kg / m³. 3 Therefore, the density of ammonia gas at 200°C is 58% of its density at 20°C. In other words, compared to operating conditions at room temperature, when the temperature of ammonia gas in a power well is 200°C, the weight of ammonia gas required to operate the power well is only 58% of the weight of ammonia gas required under operating conditions at room temperature. As a result, when the reaction tank system and the power well system are operated in sync, the amount of raw materials used, such as ammonia gas, hydrogen chloride gas, and sulfuric acid, can be significantly reduced, and energy consumption can be further reduced.
[0283] In the above embodiment, scaling up the system can enable cogeneration with industries such as the chemical fertilizer industry and the heating industry. For example, during the heating season in the northern winter, if the temperature of the ammonia gas in an ammonia gas power well is 200°C, the heat in the ammonia gas well can be transferred to the heating facility by a heat exchange facility installed in the ammonia gas power well before the ammonia gas dissolves in water. In the operation of a hydrogen chloride gas power well, the hydrogen chloride gas dissolves in an ammonium chloride solution, releasing a large amount of heat and raising the temperature of the solution. A heat exchange facility can then be installed in the solution to transfer the heat generated by the dissolution of hydrogen chloride gas into water to the heating facility. This enables cogeneration of power generation and heating, further improving energy utilization efficiency.
