Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water circulation and specifically relates to a compartment type air compression station house water circulation energy-saving system. BACKGROUND

[0002] The air compression station house water circulation equipment is a crucial auxiliary system in industrial production, mainly providing cooling and lubrication functions for compressed air equipment to ensure the stable operation of the entire compressed air system. The system is usually composed of a cooling tower, a circulating water pump, water treatment equipment, pipeline valves, a control system and other core components. In the air compression station house, the compressor generates a large amount of heat during operation, which, if not promptly dissipated, will cause the equipment temperature to be too high, affecting the normal operation efficiency of the compressor, and even possibly causing equipment damage. The water circulation equipment removes the heat generated by the compressor through a cooling water circulation system, maintaining the equipment within the optimal operating temperature range. The cooling tower, as the core component of the system, dissipates the heat in the circulating water to the atmosphere through heat exchange between water and air, achieving the recycling use of water. The circulating water pump provides power to push the cooling water to circulate in the system, ensuring that the cooling medium can continuously flow through the heat generating components.

[0003] The air compression station house water circulation equipment uses a water pump to drive the cooling water to flow in the water circulation system, which can achieve good cooling effect. However, the equipment inside the air compression station house needs to be in a working state for a long time, and the air compressor continuously generates heat during long-term operation. Therefore, the cooling water system must be continuously circulated to effectively remove the heat and ensure that the equipment temperature is maintained within a safe range. However, the bearings, mechanical seals, impellers and other moving parts of the water pump will wear out under long-term continuous operation, resulting in decreased efficiency, increased noise and increased vibration. Moreover, the long-term operation of the water pump as the power source for the cooling water in the water circulation system consumes a large amount of electricity, causing resource waste.

[0004] Therefore, in order to reduce the energy consumption of the air compression station water circulation system and recycle resources generated by the air compression station, a compartment type air compression station house water circulation energy-saving system is proposed. SUMMARY

[0005] To solve the above problems in the prior art, the application provides a compartment type air compression station house water circulation energy-saving system.

[0006] The purpose of the application can be achieved by the following technical solutions: A box-type air compressor station water circulation energy-saving system of the present invention includes a pneumatic water pump, which includes a shell and a pneumatic thrust assembly. The pneumatic thrust assembly is arranged in the shell, and the shell is provided with a water inlet, a water outlet, an air inlet and an air outlet. The compressor and the gas tank are connected through a main air pipe, and the air inlet and the air outlet are connected to the compressor and the gas tank through an air inlet pipe and an air outlet pipe respectively. The compressed gas generated by the compressor enters the shell through the air inlet and drives the pneumatic thrust assembly to push the coolant to flow from the water inlet to the water outlet and circulate. The compressed gas in the shell is discharged from the air outlet and passed into the gas tank.

[0007] Furthermore, the shell includes a propulsion chamber and a power chamber, the pneumatic thrust assembly includes a piston and a wind wheel, the wind wheel is rotatably arranged in the power chamber, the piston is slidably arranged in the propulsion chamber, the piston abuts against the wind wheel, the air inlet and the air outlet are connected to the power chamber and push the wind wheel to rotate, the water inlet and the water outlet are both connected to the propulsion chamber, the piston reciprocates vertically as the wind wheel rotates, and the piston pushes the coolant in the water inlet into the water outlet.

[0008] Furthermore, the pneumatic thrust assembly also includes a curved plate, which is coaxially connected to the wind wheel. The wind wheel is horizontally arranged in the power chamber. The top of the curved plate is a smoothly transitioned curved surface structure, and the bottom of the piston abuts against the curved plate.

[0009] Furthermore, the pistons are provided in a plurality of groups, and the pistons in the plurality of groups are respectively in contact with the highest point and the lowest point of the curved plate, and the pistons in the plurality of groups move back and forth alternately as the curved plate rotates.

[0010] Furthermore, a water inlet cavity is provided outside the water inlet on the shell, a first cover plate is provided at the bottom of the water inlet cavity, and one end of the first cover plate is hinged to the inner wall of the water inlet cavity.

[0011] Furthermore, it also includes a water outlet cavity, which is arranged outside the multiple water outlets on the shell, and a second cover plate is provided at the bottom of the water outlet cavity, and the second cover plate is hinged to the inner wall of the water outlet cavity.

[0012] Furthermore, a ball is rotatably provided at the bottom of the piston.

[0013] Furthermore, a partition is provided between two adjacent pistons, a gear is rotatably provided on the partition, teeth are provided on the side walls of the pistons, and the gears are respectively engaged with two adjacent pistons.

[0014] Furthermore, the main gas pipe is provided with a first one-way valve in the direction from the compressor to the gas tank.

[0015] Furthermore, the air outlet pipe is provided with a second one-way valve from the air outlet to the air tank.

[0016] The beneficial effects of the present invention are: (1) By changing the water pump to a pneumatic water pump, since the compressor in the air compressor station itself is used to generate compressed gas, the compressed gas generated by the compressor can be used as the power source of the pneumatic water pump. After the compressed gas generated by the compressor enters the pneumatic water pump from the air inlet, it drives the operation of the pneumatic water pump, so that the coolant in the cooling circulation system circulates, and then the compressed gas is discharged from the air outlet of the pneumatic water pump and filled into the gas tank. By using the compressed gas as the power of the pneumatic water pump, a large amount of electricity can be saved, which plays an energy-saving role. (2) The top part of the shell is the propulsion chamber, and the bottom part of the shell is the power chamber. A cylinder is formed inside the propulsion chamber. The piston is vertically slidably arranged in the shell and performs vertical reciprocating motion by abutting against the wind wheel and using the rotation of the wind wheel as power. The water inlet is at the top of the shell side wall, and the water outlet is at the top of the shell. As the piston reciprocates up and down, when the piston descends, the coolant flows from the water inlet into the propulsion chamber and then closes the water inlet. As the piston rises, it pushes the coolant out of the water outlet. This process continues, allowing the coolant to flow in the cooling circulation system. (3) A gear is set on the partition between two adjacent pistons and meshes with the pistons. The curved plate only needs to push one of the pistons at the bottom, and the other piston will drop down through the drive of the gear, forming an alternating reciprocating motion of the two gears, which can not only enable the piston to move to the bottom every time, but also avoid large friction and power loss.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figure 1-3 As shown, a box-type air compressor station water circulation energy-saving system of the present invention includes a pneumatic water pump 2, which includes a shell 201 and a pneumatic thrust assembly. The pneumatic thrust assembly is arranged in the shell 201, and the shell 201 is provided with a water inlet, a water outlet, an air inlet and an air outlet. The compressor 1 and the air tank 3 are connected through the main air pipe, and the air inlet and the air outlet are connected to the compressor 1 and the air tank 3 through the air inlet pipe 5 and the air outlet pipe 4 respectively. The compressed gas generated by the compressor 1 enters the shell 201 through the air inlet and drives the pneumatic thrust assembly to push the coolant to flow from the water inlet to the water outlet and circulate. The compressed gas in the shell 201 is discharged from the air outlet and passed into the air tank 3.

[0021] Since the equipment inside the air compressor station needs to be in working condition for a long time, the air compressor will continue to generate heat during long-term operation. Therefore, the cooling water system must maintain continuous circulation to effectively remove this heat and ensure that the equipment temperature is maintained within a safe range. The bearings, mechanical seals, impellers and other moving parts of the water pump will wear out under long-term continuous operation, resulting in reduced efficiency, increased noise, and intensified vibration. Not only that, the water pump is used as the power for cooling water in the water circulation system, and its long-term operation will also consume a lot of electricity, resulting in a waste of resources; the long-term use of the water pump will also generate heat in the air compressor station, resulting in the need to increase the cooling power accordingly; Therefore, in order to reduce the large amount of electricity required by the water pump to drive the flow of coolant in the water circulation system, in this embodiment, by replacing the water pump with a pneumatic water pump 2, since the compressor 1 in the air compression station itself is used to generate compressed gas, the compressed gas generated by the compressor 1 can be used as the power source of the pneumatic water pump 2. After the compressed gas generated by the compressor 1 enters the pneumatic water pump 2 from the air inlet, it drives the operation of the pneumatic water pump 2, causing the coolant in the cooling circulation system to circulate, and then the compressed gas is discharged from the air outlet of the pneumatic water pump 2 and filled into the gas tank 3. By using compressed gas as the power of the pneumatic water pump 2, a large amount of electricity can be saved, which plays an energy-saving role.

[0022] Furthermore, the housing 201 includes a propulsion chamber and a power chamber, and the pneumatic thrust assembly includes a piston 202 and a wind wheel 203. The wind wheel 203 is rotatably disposed in the power chamber, and the piston 202 is slidably disposed in the propulsion chamber. The piston 202 abuts against the wind wheel 203. The air inlet and the air outlet are connected to the power chamber and push the wind wheel 203 to rotate. The water inlet and the water outlet are both connected to the propulsion chamber. The piston 202 reciprocates vertically as the wind wheel 203 rotates, and the piston 202 pushes the coolant in the water inlet into the water outlet. The top part of the shell 201 is the propulsion chamber, and the bottom part of the shell 201 is the power chamber. A cylinder is formed inside the propulsion chamber. The piston 202 is vertically slidably arranged in the shell 201, and after abutting against the wind wheel 203, the rotation of the wind wheel 203 is used as power to perform vertical reciprocating motion. The water inlet is at the top of the side wall of the shell 201, and the water outlet is at the top of the shell 201. As the piston 202 reciprocates up and down, when the piston 202 descends, the coolant flows from the water inlet into the propulsion chamber and then closes the water inlet. As the piston 202 rises, it will push the coolant out of the water outlet. This process continues, allowing the coolant to flow in the cooling circulation system.

[0023] In order to prevent the piston 202 from being directly driven by the impeller 203 and causing high-pressure gas to enter the propulsion chamber and interfere with the movement of the piston 202, in one embodiment, the pneumatic thrust assembly further includes a curved plate 204, which is coaxially connected to the impeller 203. The impeller 203 is horizontally arranged in the power chamber. The top of the curved plate 204 is a smoothly transitioned curved surface structure, and the bottom of the piston 202 abuts against the curved plate 204. Curved plate 204 is the center of the circle. Its circumferential surface slides against the inner wall of the power chamber of housing 201. A rubber ring can be placed between curved plate 204 and the inner wall of the power chamber for sealing. The top of curved plate 204 has a smoothly transitioned curved surface, so its height varies periodically as it rotates. When the bottom of piston 202 abuts curved plate 204, it rotates, causing piston 202 to reciprocate up and down.

[0024] Since, in the above embodiment, only one set of pistons 202 is provided, the coolant in the cooling circulation system stops flowing when the pistons 202 descend. In order to ensure that the coolant in the cooling circulation system continues to flow, in one embodiment, multiple sets of pistons 202 are provided. The multiple sets of pistons 202 respectively abut against the highest point and the lowest point of the curved plate 204. The multiple sets of pistons 202 alternately reciprocate as the curved plate 204 rotates. By setting multiple groups of pistons 202 in the shell 201, the multiple groups of pistons 202 cooperate and alternately form up and down reciprocating motion. When one group of pistons 202 rises, another group of pistons 202 falls, forming an alternating action that causes the cooling liquid to continuously flow into the cooling circulation system. The number of pistons 202 is preferably even. When half of the pistons 202 rise, the other half of the pistons 202 are in a falling state.

[0025] Since the inside of the propulsion cavity where the piston 202 is located needs to be intermittently supplemented with cooling liquid, so that the piston 202 can push the cooling liquid filled in the propulsion cavity to the water outlet after rising. During this process, the extrusion action of the piston 202 on the cooling liquid will cause part of the cooling liquid to flow back to the water inlet, resulting in insufficient flow from the water outlet into the cooling circulation system. In order to avoid this problem, in an embodiment, a water inlet cavity is provided outside the water inlet on the shell 201, and a first cover plate 206 is provided at the bottom of the water inlet cavity. One end of the first cover plate 206 is hinged to the inner wall of the water inlet cavity. The working principle of the first cover plate 206 in the water inlet cavity is similar to that of a water well. After the piston 202 pushes the cooling liquid into the water outlet, the top of the propulsion cavity is in a vacuum state. As the piston 202 descends, the negative pressure formed in the inside of the propulsion cavity will lift the first cover plate 206 and suck the cooling liquid from the water inlet into the top of the propulsion cavity. As the amount of sucked cooling liquid increases, the gravity of the cooling liquid will press on the first cover plate 206, causing the first cover plate 206 to be in a closed state. At this time, the piston 202 rises and pushes the cooling liquid from the propulsion cavity into the water outlet, completing a cycle of action. Therefore, during the process of the piston 202 pushing the cooling liquid into the water outlet, the pressure of the piston 202 on the cooling liquid will cause the first cover plate 206 to be in a closed state, and the cooling liquid in the propulsion cavity cannot flow back from the propulsion cavity to the water inlet, thereby improving the working efficiency of the pneumatic water pump 2.

[0026] Since multiple groups of pistons 202 are set, the multiple water outlets of the multiple groups of pistons 202 need to combine the discharged cooling liquid and then combine it into the water outlet pipe. Therefore, in an embodiment, an outlet cavity is also included, which is provided outside the multiple water outlets on the shell 201. A second cover plate 207 is provided at the bottom of the outlet cavity, and the second cover plate 207 is hinged to the inner wall of the outlet cavity. By setting water outlet cavities on multiple water outlets outside the shell 201, the coolant from multiple water outlets flows into the water outlet cavity and merges. The working principle of the second cover plate 207 at the bottom of the water outlet cavity is the same as that of the first cover plate 206. After the coolant is replenished in the propulsion cavity, the piston 202 rises and pushes the coolant into the water outlet. Due to the pressure of the piston 202 on the coolant, the coolant will push the second cover plate 207 open and flow into the water outlet pipe. As the piston 202 descends, on the one hand, the coolant pressure in the water outlet cavity will press the second cover plate 207 to prevent the second cover plate 207 from leaking. On the other hand, the descent of the piston 202 will form a negative pressure in the propulsion cavity. The negative pressure in the propulsion cavity will make the seal between the second cover plate 207 and the water outlet tighter.

[0027] Since the bottom of the piston 202 is in sliding contact with the curved plate 204, as the curved plate 204 and the bottom of the piston 202 rotate relative to each other, a large friction force is generated between the curved plate 204 and the bottom of the piston 202, which not only generates a lot of noise but also causes a certain amount of power loss in the propulsion of the high-pressure gas to the coolant. To avoid this problem, in one embodiment, a ball 205 is rotatably provided at the bottom of the piston 202. The ball 205 is embedded in the bottom of the piston 202. The contact and relative sliding between the ball 205 and the curved plate 204 can greatly reduce friction, thereby reducing noise and reducing friction between the piston 202 and the curved plate 204, avoiding power loss of high-pressure gas and improving work efficiency.

[0028] Since in the above embodiment, multiple groups of pistons 202 are provided in the housing 201, and the bottom of the piston 202 is in sliding contact with the curved plate 204, the piston 202 can be pushed upward by the curved plate 204, but the descent of the piston 202 depends on the gravity of the piston 202 itself, resulting in the piston 202 being unable to return to its original position, resulting in the failure to fill the propulsion chamber with coolant each time the piston 202 is retracted, resulting in a reduction in the cooling efficiency of the circulating cooling system. If the bottom of the piston 202 is connected to the curved plate 204 by a connecting piece, and the piston 202 is pulled back by rotating the curved plate 204, the friction between the connecting piece and the curved plate 204 will cause power loss. In order to avoid this problem, in one embodiment, a partition is provided between two adjacent pistons 202, and a gear 208 is rotatably provided on the partition. Teeth are provided on the side walls of the piston 202, and the gears 208 are respectively engaged with the two adjacent pistons 202. A gear 208 is provided on the partition between two adjacent pistons 202 and meshes with the pistons 202. The curved plate 204 only needs to push one of the pistons 202 at the bottom, and the other piston 202 will be driven down by the gear 208, forming an alternating reciprocating motion of the two gears 208, which can not only enable the piston 202 to move to the bottom every time, but also avoid generating large friction and power loss.

[0029] Furthermore, a first one-way valve 7 is provided on the main gas pipe in the direction from the compressor 1 to the gas tank 3. By providing the first one-way valve 7, part of the high-pressure gas enters the pneumatic water pump 2 to be used as power to drive the operation of the pneumatic water pump 2, while the other part of the high-pressure gas can be directly stored in the gas tank 3.

[0030] Furthermore, a second one-way valve 6 is provided on the air outlet pipe 4, which extends from the air outlet to the air tank 3. By providing the second one-way valve 6, the high-pressure gas entering the pneumatic water pump 2 can return to the air tank 3 after completing the driving action, thereby preventing the backflow of the high-pressure gas. On the one hand, this avoids wasting the high-pressure gas, and on the other hand, it prevents the backflow of the high-pressure gas from hindering the operation of the pneumatic water pump 2.

[0031] Working principle: By replacing the water pump with a pneumatic water pump 2, and using the high-pressure gas generated by the compressor 1 in the air compression station as the power source, the high-pressure gas drives the rotation of the wind wheel 203, and the rotation of the wind wheel 203 drives the rotation of the curved plate 204. The top of the curved plate 204 fluctuates periodically along the direction of circular motion. The fluctuation of the top of the curved plate 204 will drive the multiple groups of pistons 202 abutting above to produce periodic alternating up and down reciprocating motions as the curved plate 204 rotates, so that the coolant in the water inlet is sucked into the propulsion chamber and is discharged through the propulsion chamber. The coolant pressure closes the first cover plate 206. As the piston 202 rises, it squeezes the propulsion chamber space to push the coolant into the water outlet. The pressure of the piston 202 squeezing the coolant will push the second cover plate 207 to open, allowing the coolant to enter the water outlet chamber. The second cover plate 207 is closed under the action of the suction force of the descending piston 202 and the coolant pressure in the water outlet chamber. The coolant is discharged into the water outlet pipe alternately through multiple groups of pistons 202, so that the coolant in the cooling circulation system continues to circulate, and the power consumption of the original water pump is reduced, which plays a better energy-saving role.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
