[Effects of the Invention]

[0007] 1. The piston-type gas-powered well energy storage power generation system has very low stability requirements, and the power well has low stability requirements during the dissolution process, allowing stability to be controlled. The thermal decomposition of ammonium hydrogen sulfate has low heating stability requirements, and heating can be achieved using power from auxiliary power generation systems such as solar energy and wind energy. In combination with a thermal power plant, ammonium hydrogen sulfite can also be heated using waste heat from thermal power generation. Alternatively, when using fossil energy such as coal for heating, the efficiency is much higher than that of thermal power generation. Thermal power generation is limited by the Carnot cycle, and the power generation efficiency of fossil energy is generally about 40%, but the energy conversion efficiency of the present invention can reach more than 90%. 2. In the piston-type gas power well energy storage and power generation system, a solution is placed at the bottom of the power well, and a piston system is set up inside the power well. The power well is filled with ammonia gas and hydrogen chloride gas that are easily dissolved in water, and the piston is raised. When the piston reaches its highest limit, the gas filled in the power well is maintained at 1 standard atmospheric pressure. Then, the rubber bag is opened to separate the solution and the gas, and the gas and the solution come into contact. During the process of the gas dissolving into the solution, the air pressure inside the power well decreases continuously, and under the influence of the atmospheric pressure outside the piston, the piston begins to descend. During the process of descending, the gravity block is lifted from a low position to a high position, and the piston reaches the lower limit of the power well. When the gravity block reaches the target position, it is also hoisted up to its highest position, causing it to move parallel to the gravity block's downwell and descend by gravity within the gravity block's downwell, which then drives the generator to generate electricity. This system can be installed anywhere, is not restricted by resources or natural conditions, allows for easy and recycled use of resources, is safe and environmentally friendly, and provides stable and reliable power generation. It also optimizes the power supply area, realizes meshing, miniaturization and unitization of the power supply area, avoids long-distance power supply across regions, reduces investment in power supply lines and power losses in power supply, and can increase or decrease the power generation load at will, synchronizing with the power consumption of the power grid in real time.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Specific embodiments of the present invention will be described in detail below with reference to the drawings. As shown in Figures 1 to 16, the present invention utilizes the characteristics of ammonia gas and hydrogen chloride gas, which are highly soluble in water and have a very large solubility, to provide a power system that is not limited by resources and natural conditions, and achieves the purpose of using such a power system to hoist a heavy load and store energy, and then using the heavy load that stores energy to generate electricity stably, or to directly generate electricity or output power using the power system.

[0010] The first aspect of this invention is a vertical power system and power generation system that are not limited by topographical conditions. A solution is filled at the bottom of a power well, and a piston system is installed inside the power well. The well is filled with water-soluble ammonia gas and hydrogen chloride gas, and the piston is raised. When the piston reaches its highest point, the gas in the power well is maintained at 1 standard atmospheric pressure. The rubber bag is then opened, separating the gas from the solution, allowing the gas and solution to come into contact. As the gas dissolves into the solution, the air pressure inside the power well decreases, and the piston begins to descend due to the influence of the atmospheric pressure outside the piston. During this process, the gravity block is lifted from a low position to a high position. When the piston reaches the bottom of the power well, the gravity block is also lifted to its highest position, causing it to move parallel to the gravity block's descending well and descend by gravity within the gravity block's descending well, which then drives a generator to generate electricity.

[0011] The gas dissolves in the solution, creating a pressure difference that causes the gravity block to lift up and store energy, and then the gravity block descends to generate 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 that are inclined and arranged according to the slope of the mountain. The power well and the direct power system have essentially the same internal structure and principle, but differ in that the power well is arranged along the slope according to its shape. A gravity block hoisting track coincides with the power well and is arranged along the slope. 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 parallel to the top of the gravity block descent track, which is also arranged along the slope like the gravity block hoisting track. The gravity block slides along the gravity block descent track to the bottom of the slope. During this process, a generator is driven to generate electricity.

[0013] The third content of the present invention is that the power well system is arranged on the ground, horizontally or along the ground, and the power well and the vertical power system are basically the same in internal structure and principle, but differ in that the power well is arranged horizontally on the ground.

[0014] The fourth aspect of this invention is that the piston of the power well drives the crankshaft to rotate via a linkage, and the power generated during the piston's up and down movement is converted into torque by the crankshaft and transmitted to the outside. The overall process is similar to that of an automobile piston engine; when four power wells are connected in parallel, it is similar to that of an in-line four-cylinder automobile engine. The output process of piston movement is two-stroke. 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 is opened, isolating the gas from the solution, and the gas comes into contact with the solution. As the gas dissolves into the solution, the air pressure inside the power well decreases continuously. Under the influence of the atmospheric pressure outside the piston, the piston begins to descend, driving the crankshaft to rotate via a linkage. The tensile force generated by the piston's downward movement is transmitted to the crankshaft via the linkage, driving it to rotate, generating torque and transmitting it to the outside. At this time, the power well completes its first stroke. When the piston reaches its lowest position, the rubber bag is filled with gas to isolate the gas from the solution, isolating the gas and solution in the well. As the piston rises, ammonia gas is filled into the well, and the gas pressure in the power well is maintained at 1 atmosphere during the gas filling process. When the piston reaches the top of the power well, the power well completes its second stroke and starts a new cycle.

[0051] As shown in FIG. 13, 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 power well system consists of a well shaft, a bottom solution pool, a surface aeration dissolution auxiliary fan well, a surface aeration dissolution auxiliary pipe, a surface isolation rubber bag, a piston, truss columns and truss beams at the top of the power well, a pulley, a motor, an ammonia gas injection pipe, a water inlet pipe, and a water outlet pipe.

[0054] (1) Izutsu The well shaft utilizes a circular structure with favorable stress conditions, and the stress structure is made of reinforced concrete, with the inner surface being lined with a smooth and flat fiber-reinforced plastic, stainless steel, resin, or other material that is resistant to corrosion by ammonium chloride solution, ammonia water solution, hydrochloric acid, ammonia gas, or hydrogen chloride gas.

[0055] At the bottom of the well, the lowest position of the piston's operation is designed, and a piston limiting block is provided on the well wall to limit the piston's further downward movement.

[0056] (2) Bottom solution pool A depth of ammonium chloride solution is placed at the bottom of the power well, forming a pool of solution at the bottom of the well.

[0057] (3) Water surface aeration and dissolution auxiliary fan well A fan is installed at the center of the bottom plate of the well to accelerate the dissolution of the gas into the solution. A steel pipe is installed at the bottom plate of the well, extending above the water surface. A motor is installed inside the steel pipe to drive and rotate the upper fan, blowing gas into the vent pipes on the solution surface. A gas blocking 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 turned 90 degrees and enters each vent pipe. The motor cable pipe may be pre-embedded in the concrete at the bottom and side walls of the well.

[0058] (4) Water surface aeration dissolution auxiliary pipe Radial vent pipes are installed every 45° around the fan well, and are connected to the fan well. Two annular vent pipes are installed on the radial pipes, connecting the ends of the radial pipes with the midpoints, promoting the flow of gas in the fan well through the aeration and dissolution support pipes.

[0059] An open-cell sponge foam is wrapped around the vent pipe, and several diffusing holes are formed at the top and bottom of the vent pipe to quickly diffuse the gas in the vent pipe into the open-cell sponge foam wrapped around the vent pipe, so that the gas comes into sufficient contact with the water body in the sponge foam and dissolves into solution.

[0060] (5) Surface isolation rubber bag A circular rubber bag is fixed to the outer wall of the fan well on the water surface. When filled with gas, the rubber bag expands to cover the entire liquid surface, isolating the liquid surface from the ammonia gas in the power well and preventing the ammonia gas from coming into contact with the ammonium chloride solution and dissolving in the ammonium chloride solution.

[0061] When ammonia gas needs to dissolve into solution, the gas in the rubber bag is released, causing the bag to shrink toward the wall of the fan well, exposing the liquid surface.

[0062] (6) Piston The piston is a member that moves up and down in accordance with changes in the pressure of gas inside the cylinder, and is similar to the piston in an internal combustion engine.

[0063] In order to reduce the weight of the piston and improve the overall rigidity of the piston, the piston uses a flat truss structure and an elevation truss structure made of lightweight steel. The piston is circular, and a stainless steel plate is provided at the bottom of the flat truss of the piston to isolate it from the outside air.

[0064] The contact point between the piston and the well is a rigid side wall of a certain height, and rollers are provided at the upper and lower ends of the side wall. The rollers provide support between the piston and the well wall, reducing the frictional force between the piston and the well wall when the piston is operating.

[0065] Two piston gas sealing rings, similar to the gas ring and oil ring in an internal combustion engine piston, are installed between the support rollers at the upper and lower ends of the piston sidewall. A water tank is installed inside the piston sidewall, containing water, and a water inlet hole is formed at the top. When the water tank runs low on water, water can be added through the water inlet hole. A connecting pipe is installed between the water tank and the two gas rings, allowing water to fill the gap between the two sealing rings, forming a water ring. During piston movement, the water ring completely isolates the ammonia gas inside the well from the atmosphere outside the well, preventing the ammonia gas from leaking into the atmosphere. During piston movement, the water ring also provides a lubricating effect, reducing friction between the piston ring and the well wall.

[0066] A wire rope connecting buckle is provided at the top of the piston vertical truss, onto which the wire rope is connected.

[0067] (7) Truss columns and beams, pulleys, and motors above the power well A truss column and a truss beam are provided above the power well, and the truss beam is spanned over the truss column.

[0068] A pulley is attached to 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 power well with ammonia gas, the motor drives and rotates the pulley, winding up the piston, and synchronizing the winding up of the piston with the ammonia gas filling process in the power well until the power well is filled with ammonia gas at 1 atmosphere and the piston is wound up to its upper limit position. 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 in the well wall, with the outlet at the lower end located between the rubber bag and the piston limiting block, and the upper end connected to the ammonia gas storage tank.

A water pump and valve are installed at the lower end of the pipe, and the water pump and valve are opened when it is necessary to pump the solution in the power well into the "pool for 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 points.

[0073] (1) Hydrogen chloride gas is injected into the power well, and the hydrogen chloride gas injection gas pipe is installed in the well wall, with the lower outlet located between the rubber bag and the piston limiting block, and the upper end connected to the hydrogen chloride gas storage tank.

[0166] The ammonia gas storage tank has a diameter of 20m, a height of 20m, and an internal pressure of 1 to 2 times atmospheric pressure (100 to 200Kpa), which is 6280 to 12560m at standard atmospheric pressure. 3 The ammonia gas storage tank can store 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 to supply ammonia gas to the ammonia gas power well, and the other end is connected to the 1# and 2# reaction tanks via piping to supply ammonia gas to the ammonia gas storage tank.

[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 12560m at standard atmospheric pressure. 3 The storage capacity is 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 to supply hydrogen chloride gas to the hydrogen chloride gas power well, and the other end is connected to the 1# and 2# reaction tanks via piping to supply hydrogen chloride gas to the hydrogen chloride gas storage tank.

[0168] The inner diameter of the ammonia gas power well is 10m, the depth of the ammonium chloride solution at the bottom is 10m, the ammonium chloride solution is the mother liquid for dissolving ammonia gas, and its volume can meet the dissolution requirements of the total amount of ammonia gas required for the power well's daily operation. The piston stroke is 50m, the piston diameter is 10m, and the volume of the power well within the piston stroke range is 3925m. 3 When the power 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 power well cannot reach a complete vacuum state during operation, if the vacuum level in the power well is 70%, the pressure difference between the internal and external gas acting on the piston is 809 x 70% = 566t, which is the standard value for the weight of the gravity block lifted by the power well, i.e., the weight of the gravity block is 566t (for convenience of explanation, the weight of the piston system is ignored).

[0169] The parameters for hydrogen chloride gas-powered wells are the same as those for ammonia gas-powered wells.

[0170] The gravity block is made of reinforced concrete, has dimensions of length x width x height = 5.5 x 5.5 x 7.5 m, and weighs 566 t.

[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 downwell is a rectangular well with internal dimensions of 6.0 x 6.0 m and a depth of 57.5 m.

[0173] The ammonium chloride solution pool, which contains aqueous ammonia, is 14 m in diameter and 11 m deep.

[0174] The pool of ammonium chloride solution containing hydrochloric acid is 14m in diameter and 11m deep.

[0175] The mixing pool (ammonium chloride solution pool, ammonium chloride crystal precipitation pool) containing aqueous ammonia solution, aqueous ammonia solution, and hydrogen chloride solution has a diameter of 20 m, a side wall depth of 11 m, and a funnel at the bottom. The bottom of the funnel is a centrifugal drum for recovering ammonium chloride solids, and the diameter of the centrifugal drum is 4 m.

[0176] The ammonium chloride solution storage pool is 14m in diameter and 11m deep.

[0177] Initial state of the system: The power well is filled with ammonium chloride solution at the design water 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 filled to its full capacity, and the gravity block is located at the bottom of the gravity block winding 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] The solution surface comes into contact with the ammonia gas in the well, causing the ammonia gas to dissolve in the ammonium chloride solution. As the ammonia gas dissolves in the ammonium chloride solution, the air pressure in the well drops, causing the piston to begin to descend. The wire rope and pulley system lifts up the gravity block of the gravity block lifting well. When the piston operates to the lower limit block of the power well, the gravity block is lifted up to the wellhead of the gravity block lifting well. The movable track at the wellhead of the gravity block lifting 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 a track laid between the gravity block lifting well and the gravity block down well to the wellhead of the gravity block down well. The track at the wellhead of the gravity block down well is retracted, and the gravity block descends along the gravity block down well. During the descent, the wire rope and pulley system drives a generator to rotate and generate electricity. For the gravity block, after descending to the bottom of the well, the gravity block moves along the tunnel to the bottom of the hoisting well, where it is in the initial state and the next cycle begins.

[0180] During the process of the gravity block descending to generate 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 in the power well. The motor of the truss pulley at the power well mouth winds up the piston, and during the piston rising, the ammonia gas storage tank fills the ammonia gas power well with gas, and when the piston reaches the top, the ammonia gas in the ammonia gas power well becomes standard atmospheric pressure. At this time, 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 per hour, and, assuming a 22-hour operation per day, completes 110 cycles.

[0182] During operation, the dissolution speed of ammonia gas can be further accelerated by using a dissolution assist fan, and the number of cycles can be increased.

[0183] The circulation period of the ammonium chloride solution in the ammonia gas power well is 1 day, and the solution exchange time is 2 hours.

[0184] The dissolution rate of ammonia gas in an ammonia gas power well slows as the concentration of ammonia in the solution increases. If the natural dissolution rate does not meet the requirements, the water surface aeration dissolution auxiliary fan can be started to blow ammonia gas into the water surface aeration dissolution auxiliary pipe, accelerating the dissolution process of ammonia gas and shortening the circulation time.

[0185] Hydrogen chloride power wells and ammonia gas power wells have the same operating process, but 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 power well and one hydrogen chloride power well simultaneously power one gravity block descending well power generation system. By adjusting the descending speed of the gravity block, the system can be continuously operated, and the power generation rate can be synchronized with the circulation cycle of the power well.

[0187] To improve the system operation guarantee rate, some gravity blocks may be pre-placed on the ground.

[0188] By staggering the solution exchange time of the ammonia gas power well from the solution exchange time of the hydrogen chloride gas power well and setting the solution exchange time during the peak period of power demand, it is possible to meet uninterrupted power generation during the system operation process.

[0189] Alternatively, multiple such systems can be connected in parallel and the solution exchange times of each system staggered to achieve uninterrupted power generation.

[0190] When exchanging the solution in an ammonia gas power well, the solution is pumped into an ammonium chloride solution pool containing aqueous ammonia, and then saturated ammonium chloride solution previously stored in the ammonium chloride solution storage pool is injected into the ammonia gas power well to complete the solution exchange.

[0191] 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 saturated ammonium chloride solution previously 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 of the ammonia gas-powered well can be synchronized with the water injection process of the hydrogen chloride gas-powered well, and vice versa, in this way the energy generated by water injection can be used for pumping, saving the energy consumption of solution exchange.

[0193] When the ammonia content in the ammonium chloride solution pool containing aqueous ammonia and the hydrochloric acid content in the ammonium chloride solution pool are measured, the solutions in each pool are injected into a "mixed pool containing aqueous ammonia, aqueous ammonia, and hydrogen chloride solutions (ammonium chloride solution pool, ammonium chloride crystal precipitation pool)" at the ratios that allow them to react completely with each other. The ammonia and hydrogen chloride in the mixed solution in the pools react chemically to produce ammonium chloride, causing the ammonium chloride solution to become supersaturated, resulting in ammonium chloride crystallization and precipitation within the pools. The ammonium chloride solids are separated and collected by a centrifugal drum at the bottom of the pool. The system takes one day to complete a cycle, which is the same as the solution exchange period for the power well.

[0194] The collected ammonium chloride solids are transported to the 1# and 2# reaction tanks, where they are used in the ammonia gas and hydrogen chloride gas regeneration system to complete the production of ammonia gas and hydrogen chloride gas. They are 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 one day, which is the same as the operation cycle of the ammonium chloride crystal precipitation pool. In other words, the ammonium chloride crystal precipitation pool can process all the solutions exchanged in one day in the ammonia gas power well and hydrogen chloride gas power well, and then transport the generated and collected ammonium chloride solids to the ammonia gas / hydrogen chloride gas regeneration system.

[0196] The ammonia gas and hydrogen chloride gas regeneration system's reaction tanks take 11 hours to produce ammonia gas and 11 hours to produce hydrogen chloride gas, for a total of 22 hours, matching the operating time of the power well system. Reaction tanks 1# and 2# operate alternately; that is, when reaction tank 1# produces ammonia gas, reaction tank 2# produces hydrogen chloride gas, and when reaction tank 2# produces ammonia gas, reaction tank 1# produces hydrogen chloride gas. In this way, the ammonia gas and hydrogen chloride gas regeneration system operates in sync with the power well system, providing synchronized gas supply, improving gas supply reliability and reducing energy consumption during the gas storage process.

[0197] If the mass of the gravity block lifted by the power well in one go is 566 tons, the lifting height is 50 m, the gravitational potential energy stored in one go is 277,332,650 joules, and the generator efficiency is 95%, the gravitational potential energy stored in one go is converted into 73 kWh of electrical energy. If one power well cycles 110 times per day, the power output of one power well is 8,050 degrees per day. As the above system has one ammonia gas power well and one hydrogen chloride gas power well, the power output of the above system is 16,100 degrees per day. The annual power output is 5.88 million degrees.

[0198] During the operation of the above system, the energy consumption required for solution exchange in the power well, and gas transportation between the reaction tank and the gas storage tank, and between the gas storage tank and the power well, is almost negligible. The largest energy demand is the reaction heat required to heat the ammonium hydrogen sulfate in the reaction tank to about 200°C and decompose the ammonium hydrogen sulfate in the process of producing ammonia gas in the reaction tank.

[0199] Example 2 The second embodiment is a power system and a power generation system that can significantly reduce investment when there is a mountainous terrain condition, based on the condition of the slope land along the mountain.

[0200] In Example 2, an example is taken of a mountain slope with an elevation difference of 100 m and a gradient of 1:1. In actual construction, the slope track system can be deployed along the slope according to the gradient changes and is not limited to a single gradient.

[0201] Example 2 is composed 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 track, a gravity block descent track, 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, etc.

[0202] The ammonia gas storage tank has a diameter of 34m, a height of 20m, and an internal pressure of 1 to 2 times atmospheric pressure (100 to 200Kpa), which is 18,150 to 36,298m at standard atmospheric pressure. 3 The ammonia gas storage tank can store 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, and supplies ammonia gas to the ammonia gas power well. The other end is connected to the 1# and 2# reaction tanks via piping, and the reaction tanks supply ammonia gas to the ammonia gas storage tank.

[0203] The hydrogen chloride gas storage tank has a diameter of 34m, a height of 20m, and an internal pressure of 1 to 2 times atmospheric pressure (100 to 200Kpa), which is 18,150 to 36,298m at standard atmospheric pressure. 3 The storage capacity is 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, and supplies hydrogen chloride gas to the hydrogen chloride gas power 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 inner diameter of the ammonia gas power well is 10m, the depth of the ammonium chloride solution at the bottom is 30m, the ammonium chloride solution is the mother liquid for dissolving ammonia gas, and its volume is sufficient to dissolve the total amount of ammonia gas required for the power well's daily operation. The piston stroke is 141m, the piston diameter is 10m, and the volume of the power well within the piston stroke range is 11,135m. 3When the power well is in a vacuum state, the external atmospheric pressure acting on the piston is 809 tons. Taking into account operating efficiency and the fact that the power well cannot reach a complete vacuum state 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 x 70% = 566 tons, which is the standard value for the power well's hoisting capacity (for ease of explanation, the weight of the piston system is ignored). When the gradient of the gravity block hoisting orbit is 1:1, the weight of the gravity block is 566 / sin(45°) = 801, i.e., the weight of the gravity block is 801 tons.

[0205] The parameters for hydrogen chloride gas-powered wells are the same as those for ammonia gas-powered wells.

[0206] The gravity block is made of reinforced concrete, has dimensions of length x width x height = 6.84 x 6.84 x 6.84 m, and weighs 801 t.

[0207] The gravity block hoisting track, gravity block sliding track, slope bottom ground track, and slope top ground track use the train tracks, and two pairs of wheels corresponding to the tracks are installed at the bottom of the gravity block and use the train wheels.

[0208] The ammonium chloride solution pool containing aqueous ammonia is 17m in diameter and 20m deep.

[0209] The pool of ammonium chloride solution containing hydrochloric acid is 17m in diameter and 20m deep.

[0210] The mixing pool (ammonium chloride solution pool, ammonium chloride crystal precipitation pool) containing the aqueous ammonia solution and hydrogen chloride solution has a diameter of 20 m, a side wall depth of 20 m, and a funnel at the bottom. At the bottom of the funnel is a centrifugal drum for recovering ammonium chloride solids, and the diameter of the centrifugal drum is 4 m.

[0211] The ammonium chloride solution storage pool is 17m in diameter and 20m deep.

[0212] Initial state of the system: The power well is filled with ammonium chloride solution at the design water 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 filled to its full capacity, and the gravity block is located at the bottom of the gravity block hoisting track.

[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] The solution surface comes into contact with the ammonia gas in the well, dissolving into the ammonium chloride solution. As the ammonia gas dissolves in the ammonium chloride solution, the air pressure in the well drops, 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 reaches the lower limit block of the power well, the gravity block is hoisted to the top of the slope. When the gravity block reaches the top of the slope platform, it rotates its track 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 slope on the gravity block sliding track, rotates its track 90 degrees, and connects to the gravity block sliding track. The gravity block slides along the gravity block sliding track. During the sliding process, the wire rope and pulley system drives the generator to rotate and generate electricity. When the gravity block slides down to the platform at the bottom of the slope, it rotates the track it is on by 90 degrees, connects to the ground track at the bottom of the slope, moves along the ground track at the bottom of the slope to the gravity block lifting track, rotates the track it is on by 90 degrees, and connects to the gravity block lifting track, starting the next cycle.

[0215] During the process of the gravity block sliding to generate 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 in the power well. The motor of the truss pulley at the power well mouth winds up the piston, and during the piston rising, the ammonia gas storage tank fills the ammonia gas power well with gas, and when the piston reaches the top, the ammonia gas in the ammonia gas power well becomes standard atmospheric pressure. At this time, 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 per hour, and, assuming a 22-hour operation per day, completes 110 cycles.

[0217] During operation, the dissolution speed of ammonia gas can be further accelerated by using a dissolution assist fan, and the number of cycles can be increased.

[0218] The circulation period of the ammonium chloride solution in the ammonia gas power well is 1 day, and the solution exchange time is 2 hours.

[0219] The dissolution rate of ammonia gas in an ammonia gas power well slows as the concentration of ammonia in the solution increases. If the natural dissolution rate does not meet the requirements, the water surface aeration dissolution auxiliary fan can be started to blow ammonia gas into the water surface aeration dissolution auxiliary pipe, accelerating the dissolution process of ammonia gas and shortening the circulation time.

[0220] Hydrogen chloride power wells and ammonia gas power wells have the same operating process, but 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 power well and one hydrogen chloride power well simultaneously power one gravity block sliding orbital power generation system. The descent speed of the gravity block is adjusted to complete the continuous operation of the system, and the circulation cycle of the power wells and the power generation rate are synchronized.

[0222] To improve the system operation guarantee rate, some gravity blocks may be pre-placed at the top of the slope.

[0223] By staggering the solution exchange time of the ammonia gas power well from the solution exchange time of the hydrogen chloride gas power well and setting the solution exchange time during the peak period of power demand, it is possible to meet uninterrupted power generation during the system operation process.

[0224] Alternatively, multiple such systems can be connected in parallel and the solution exchange times of each system staggered to achieve uninterrupted power generation.

[0225] When exchanging the solution in an ammonia gas power well, the solution is pumped into an ammonium chloride solution pool containing aqueous ammonia, and then saturated ammonium chloride solution previously stored in the ammonium chloride solution storage pool is injected into the ammonia gas power 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 saturated ammonium chloride solution previously stored in the ammonium chloride solution storage pool is injected into the hydrogen chloride gas powered well to complete the solution exchange.

[0227] The pumping process of the ammonia gas-powered well can be synchronized with the water injection process of the hydrogen chloride gas-powered well, and vice versa, in this way the energy generated by water injection can be used for pumping, saving the energy consumption of solution exchange.

[0228] When the ammonia content in the ammonium chloride solution pool containing aqueous ammonia and the hydrochloric acid content in the ammonium chloride solution pool are measured, the solutions in each pool are injected into a "mixed pool containing aqueous ammonia, aqueous ammonia, and hydrogen chloride solutions (ammonium chloride solution pool, ammonium chloride crystal precipitation pool)" at the ratios that allow them to react completely with each other. The ammonia and hydrogen chloride in the mixed solution in the pools react chemically to produce ammonium chloride, causing the ammonium chloride solution to become supersaturated, resulting in ammonium chloride crystallization and precipitation within the pools. The ammonium chloride solids are separated and collected by a centrifugal drum at the bottom of the pool. The system takes one day to complete a cycle, which is the same as the solution exchange period for the power well.

[0229] The collected ammonium chloride solids are transported to the 1# and 2# reaction tanks, where they are used in the ammonia gas and hydrogen chloride gas regeneration system to complete the production of ammonia gas and hydrogen chloride gas. They are 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 one day, which is the same as the operation cycle of the ammonium chloride crystal precipitation pool. In other words, the ammonium chloride crystal precipitation pool can process all the solutions exchanged in one day in the ammonia gas power well and hydrogen chloride gas power well, and then transport the generated and collected ammonium chloride solids to the ammonia gas / hydrogen chloride gas regeneration system.

[0231] The ammonia gas and hydrogen chloride gas regeneration system's reaction tanks take 11 hours to produce ammonia gas and 11 hours to produce hydrogen chloride gas, for a total of 22 hours, matching the operating time of the power well system. Reaction Tank 1# and Reaction Tank 2# operate alternately; that is, when Reaction Tank 1# produces ammonia gas, Reaction Tank 2# produces hydrogen chloride gas, and when Reaction Tank 2# produces ammonia gas, Reaction Tank 1# produces hydrogen chloride gas. In this way, the ammonia gas and hydrogen chloride gas regeneration system operates synchronously with the power well system, providing synchronized gas supply, improving gas supply reliability and reducing energy consumption during the gas storage process.

[0232] Assuming the mass of the gravity block lifted by the power well in one go is 801 t, the lifting height is 100 m, the gravitational potential energy stored in one go is 784,727,702 joules, and the generator efficiency is 95%, the gravitational potential energy stored in one go is converted into 207 kWh of electrical energy. If one power well cycles 110 times per day, the power output of one power well is 22,800 degrees Celsius per day. As the above system has one ammonia gas power well and one hydrogen chloride gas power well, the power output of the above system is 45,560 degrees Celsius per day. The annual power output is 5.88 million degrees Celsius.

[0233] During the operation of the above system, the energy consumption required for solution exchange in the power well, and gas transportation between the reaction tank and the gas storage tank, and between the gas storage tank and the power well, is almost negligible. The largest energy demand is the reaction heat required to heat the ammonium hydrogen sulfate in the reaction tank to about 200°C and decompose the ammonium hydrogen sulfate in the process of producing ammonia gas in the reaction tank. Example 3

[0234] The power well in Example 1 requires either a vertical well to be constructed below ground level or a complex support structure to be installed above ground level. The power well in Example 2 requires construction along a slope along a mountain, which can be difficult if the slope is not flat.

[0235] In both Examples 1 and 2, there is a problem that the construction of the power well is difficult and the construction cost is high.

[0236] As an optimization of the power well, a power well can be constructed in the ground as shown in FIG.

[0237] For example, if the ground is horizontal, 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 power well's solution pool. In this configuration, most of the power well is positioned 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 and forms an obtuse angle greater than 90 degrees or an acute angle less than 90 degrees with the solution pool of the power well.

[0239] The operation process of the power well in this embodiment is the same as that of the power wells in the first and second embodiments. Example 4

[0240] In Examples 1 and 2, the power well lifts up the gravity block to store potential energy, and then the power block converts the potential energy into kinetic energy, completing the power generation process.

[0241] In the fourth embodiment, the power well drives a crankshaft connected to a piston of the power well, so that the power of the power well is directly output by the crankshaft. See Figs. 12 and 13.

[0242] Four ammonia gas power wells are taken 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# are in the same operating state as a pair, and power wells 2# and 3# are in the same operating state as a pair.

[0244] Initial state: The pistons of the 1# and 4# power wells are at the lower limit position, and the pistons of the 2# and 3# power wells are at the upper limit position.

[0245] When gas is released from the gas-filled rubber bags of the #2 and #3 power 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 within the well. Under atmospheric pressure, the piston descends, driving the crankshaft to rotate and output power to the outside. When the piston reaches its lowest position, gas is filled into the gas-filled rubber bags of the #2 and #3 power wells. The rubber bags then cover the entire water surface, and the pistons rotate and rise, filling the power wells with ammonia gas. During the gas-filling process, the ammonia gas pressure in the power wells is always maintained at 1 atmosphere. When the piston reaches its highest position, the ammonia gas filling pipe is closed. At this point, one complete process is completed and the next cycle begins.

[0246] Gas is filled into the gas-filled rubber bags of the #1 and #4 power wells, covering the entire water surface. As the pistons rotate and rise, ammonia gas is filled into the power wells. During the gas-filling process, the ammonia gas pressure in the power wells is maintained at 1 atmosphere. When the pistons reach their upper limit, the ammonia gas filling pipes are closed and the gas is released from the gas-filled rubber bags of the #1 and #4 power wells. The rubber bags then 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 pistons descend until they reach their lower limit, driving the crankshaft to rotate and outputting power to the outside. At this point, one complete process is completed 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] During the process of the piston descending, the dissolution assist fan can be used to accelerate and control the descending speed of the piston.

[0249] As in the above example, by combining the power well with an ammonia gas / hydrogen chloride gas regeneration system, each power well can be operated continuously.

[0250] The power operating process of this embodiment is similar to the operating process of a piston in an internal combustion engine, except that an internal combustion engine is a heat engine, has a small cylinder volume, a high rotational speed, and performs work by expanding a gas, whereas this embodiment is not a heat engine, has a large cylinder volume, a low rotational speed, and performs work by generating negative pressure as the gas dissolves in a solution and contracts.

[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, or may be used in other power applications such as mining, machinery, etc.

[0252] Example 5 Ammonia gas and hydrogen chloride gas regeneration system.

[0253] It consists of two reaction tanks and the associated liquid ammonia storage tank, liquid hydrogen chloride storage tank, ammonia gas storage tank, and hydrogen chloride gas storage tank. See Figures 15, 16, and 17.

[0254] Liquid ammonia storage tanks and liquid hydrogen chloride storage tanks are cylindrical steel tanks with linings made of fiber-reinforced plastic, stainless steel, resin, etc. that are resistant to corrosion by ammonia gas and hydrogen chloride gas. Liquid ammonia storage tanks and liquid hydrogen chloride storage tanks are intended to improve the ammonia gas and hydrogen chloride gas assurance rate of power well systems, but are not essential equipment for the system, and their volume size and whether or not they are installed can be determined according to the requirements of the system.

[0255] The ammonia gas storage tank and hydrogen chloride gas storage tank are transient systems connecting the reaction tank and the power well. They temporarily store the ammonia gas and hydrogen chloride gas produced in the reaction tank and improve the system's gas supply guarantee rate. The pressure of the storage tank can be 100-200 kPa. When the power well's piston rises, the storage tank serves to connect the reaction tank and the power well. When the power well's piston falls, there is no need to supply gas to the power well, and at this time, the gas produced in the reaction tank is temporarily stored in the storage tank.

[0256] Chemical reaction process in the reaction tank: Sulfuric acid is present in the reaction tank, and the ammonium chloride solids produced in the ammonium chloride crystal precipitation pool in the power well system react chemically with the sulfuric acid in the reaction tank to produce ammonium hydrogen sulfate and hydrogen chloride gas. The chemical reaction equation is H4Cl + H2SO4 === NH4HSO4 + HCl↑, and the produced hydrogen chloride gas is transported via piping to the hydrogen chloride gas storage tank. What remains in the reaction tank is ammonium hydrogen sulfite. The ammonium hydrogen sulfate is heated to approximately 200°C and thermally decomposed into ammonia gas and sulfuric acid. The produced ammonia gas is transported via piping to the ammonia gas storage tank. After the reaction is complete, what remains in the reaction tank is sulfuric acid, and the reaction tank returns to its initial state.

[0257] Take Example 1 as an example.

[0258] Two reaction tanks are considered as one set, and the treatment capacity of one set of reaction tanks must satisfy the amount of ammonium chloride produced in one day by one ammonia gas power well and one hydrogen chloride power well system.

[0259] The ammonia gas power well consumes 334 tons of ammonia gas per day, the hydrogen chloride power well consumes 640 tons of hydrogen chloride gas per day, and the total weight of ammonium chloride produced by the entire system per day is 974 tons. The amount of ammonium chloride processed in one reactor tank is 974 / 2 = 487 tons. The time required to produce ammonia gas for one reactor tank is the same as the time required to produce hydrogen chloride gas, which corresponds to the operating time of the power system. That is, the time required to produce ammonia gas for one reactor tank is 11 hours, and the time required to produce hydrogen chloride gas is 11 hours. The two reactor tanks operate alternately, so that when reactor 1 produces ammonia gas, reactor 2 produces hydrogen chloride gas.

[0260] Since one reaction tank needs to process 487 tons of ammonium chloride, the reaction tank must have at least 891 tons of sulfuric acid to meet the reaction demand with ammonium chloride.

[0261] The diameter of the reaction tank is 10m. As a conservative design, the reaction tank is pre-filled with 1000t of sulfuric acid, and the bulk density of the sulfuric acid is 1840kg / m 3 and the depth of the sulfuric acid solution in the reaction tank is 6.9 m.

[0262] When 487 tons of ammonium chloride reacts with sulfuric acid in the reaction tank, the weight of the ammonium hydrogen sulfate produced is 1225 tons, the bulk density of the ammonium hydrogen sulfate is 1780 kg / m3, and the depth of the ammonium hydrogen sulfate in the reaction tank is 8.8 m.

[0263] The height of the reaction tank is 20m to leave enough space for chemical reaction and some gas storage space inside the reaction tank.

[0264] Initial state of two reaction tanks: Each tank is filled with 1000 tonnes of sulfuric acid.

[0265] Reaction tank 1: 487 tons of ammonium chloride is added to the reaction tank at a rate of 0.74 tons / min through the ammonium chloride supply pipe and sprayer at the top of the reaction tank. The added ammonium chloride reacts with the sulfuric acid in the reaction tank to produce hydrogen chloride gas and ammonium hydrogen sulfate. The hydrogen chloride gas is transported to the hydrogen chloride gas storage tank through the hydrogen chloride gas transport pipe and air pump at the top of the reaction tank. After 11 hours, all 487 tons of ammonium chloride has been added, the reaction is complete, and the substance in the reaction tank is now ammonium hydrogen sulfate.

[0266] The electromagnetic heating systems at the bottom, body and inside the stirring blades of the reaction tank are activated, heating the ammonium hydrogen sulfate in the reaction tank to approximately 200°C, causing the ammonium hydrogen sulfate in the reaction tank to thermally decompose into sulfuric acid and ammonia gas. The generated ammonia gas is transported to the ammonia gas storage tank by the ammonia gas transport piping and air pump installed at the top of the reaction tank.

[0267] By using measures such as layered heating, heating temperature control, and intermittent heating, the decomposition rate of ammonium hydrogen sulfate can be controlled and decomposed at a constant rate within 11 hours. For example, first, the electromagnetic heating system for the stirring blade in the top layer and the electromagnetic heating system for the upper part of the body are activated, and then the stirring blade and the electromagnetic heating system in the body are activated layer by layer. After all the ammonium hydrogen sulfate has decomposed, the substance remaining in the reaction tank is sulfuric acid, and the initial state is restored.

[0268] When hydrogen chloride gas begins to be produced in the first reactor, the second reactor starts operation, adding ammonium chloride and starting the process of producing ammonia gas. By operating alternately in this way, the system consisting of the two reactors simultaneously produces ammonia gas and hydrogen chloride gas during 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 heat source system for a reaction tank.

[0270] In each of the above examples, the main energy consuming process is the heating of ammonium hydrogen sulfate in the reaction tank to produce ammonia gas.

[0271] In each of the above embodiments, due to the operating characteristics of the system and the existence of the gas storage system, the requirements for the stability of the operation of the power well and reaction tank of the entire system are extremely low.

[0272] Power wells have low requirements for stability in the operation process, and can be fast or slow, or fast or slow, in the gas dissolution process;

[0273] The thermal decomposition of ammonium hydrogen sulfate in the reaction tank requires low stability, and the decomposition process can be fast or slow, fast or slow, or intermittent. 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 supply three cycles of the ammonia gas power well, with one cycle lasting 12 minutes and three cycles lasting 36 minutes. That is, the reaction tank can be stopped for approximately 30 minutes during the ammonia gas production process. Increasing the pressure of ammonia gas in the ammonia gas storage tank or the volume of the storage tank reduces the stability requirements of the reaction tank of the system.

[0274] When ammonia gas is pressurized to 1.06 MPa at an ambient temperature of 30°C, it changes from a gas to a liquid state and reaches a depth of 1 m. 3 of liquid ammonia is 790m 3 Considering that the main energy consumption process of the system is heating ammonium hydrogen sulfate to produce ammonia gas, and ammonia gas is easily stored in a liquid state, the system can increase the storage capacity of liquid ammonia and further reduce the requirements for the stability of the reaction tank to produce 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 The amount of ammonia gas used over the two days was 866,000 m 3 When the ammonia gas power well converts the ammonia gas used for two days into liquid ammonia, the volume of liquid ammonia is 1097 m 3 That is, one approximately 1100m 3The liquid ammonia storage tank alone can hold the amount of ammonia gas required to operate an ammonia gas powered well for two days.

[0276] As described above, in order to heat ammonium hydrogen sulfate in the reaction tank to produce ammonia gas, the requirement for the stability of the heat source is very low, and the heat source for the reaction tank can be provided by using the power of an auxiliary power generation system such as solar energy or wind energy, which has unstable power generation.

[0277] Coal can be used to directly provide thermal energy to the reaction tank. As is well known, the thermal efficiency of a typical thermal power plant is only 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 over 90%. In other words, if this power generation system is scaled up and the reaction tank is heated entirely with coal instead of a thermal power plant, the utilization rate of the thermal efficiency of the coal will be over 90%, 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 exhaust gas and steam from the thermal power plant may be utilized, and flue gas and steam pipes may be arranged spirally inside the reaction tank to heat ammonium hydrogen sulfate in the reaction tank, which may then be used as a heat source for the reaction tank.

[0279] In combination with an ocean-going cargo ship, the exhaust gas from the cargo ship's large engine can be used as a heat source for the reaction tank, becoming an auxiliary power system for the cargo ship and improving the fuel energy utilization rate of the ocean-going wheel.

[0280] The system may be used in trucks or small cars and may be miniaturized for use as the vehicle's power system.

[0281] Example 7 In the above example, the gas temperature in the power well is 20°C, which is normal temperature, and the temperature of the gas produced in the reaction tank is not taken into consideration.

[0282] In the above embodiment, by forming a scale and system, the production process in the reaction tank and the operation process of the power well can be perfectly synchronized, thereby maximizing the energy utilization rate. 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 to the power well will also be 200°C. At 1 standard atmospheric pressure, the density of ammonia gas at 20°C is 0.759 kg / m 3 and the density at 200°C is 0.438 kg / m 3 That is, the density of ammonia gas at 200°C is 58% of its density at 20°C. That is, compared to operating conditions at room temperature, when the temperature of the ammonia gas in the 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. Therefore, when the reaction tank system and the power well system are operated synchronously, the amounts of raw materials such as ammonia gas, hydrogen chloride gas, and sulfuric acid used can be significantly reduced, and energy consumption can also be reduced.

[0283] In the above embodiment, if scaled up, cogeneration with the chemical fertilizer industry, heating industry, etc. can also be realized. For example, during the winter heating season in the north, if the temperature of the ammonia gas in the ammonia gas power well is 200°C, a heat exchanger installed in the ammonia gas power well can transfer the heat in the ammonia gas well to the heating facility before the ammonia gas dissolves in water. During the operation of the hydrogen chloride gas power well, the hydrogen chloride gas dissolves in the ammonium chloride solution, releasing a large amount of heat and raising the temperature of the solution. A heat exchanger can be installed in the solution to transfer the heat generated by the hydrogen chloride gas dissolving in water to the heating facility. This realizes cogeneration of power generation and heating, further improving energy utilization efficiency.
