Description

Technical Field

[0001] The present invention relates to the technical field of heat energy recovery equipment, and particularly to an air compressor heat energy recovery and utilization device and its usage method. Background Art

[0002] Under the background of current industrial energy conservation and carbon neutrality, the air compressor heat energy recovery device has become a standard equipment for the manufacturing industry in 2025. This device realizes efficient conversion of waste heat through a three-stage energy capture architecture: First, a high-temperature alloy shell-and-tube heat exchanger (with a pressure resistance of 2.0 MPa / 250 °C) intercepts the waste heat of compressed air at 80 - 200 °C, and cooperates with a graphene-coated plate heat exchanger to synchronously recover the low-temperature heat of lubricating oil at 60 - 90 °C; Subsequently, an intelligent grading system is adopted to introduce high-temperature heat into an organic Rankine cycle power generation module (the thermal efficiency of the 2024 model of Hanbell Precision Machinery reaches 24%), and medium- and low-temperature heat drives an absorption heat pump (the latest COP of Gree is 5.1) to provide clean heat source for the workshop.

[0003] After the compressed gas with heat energy in the air compressor enters the heat exchange device, water vapor, carbon dioxide (CO 2 ), trace sulfur oxides (SO x ), and nitrogen oxides (NO x ), in the compressed air have increased solubility under high pressure. When the high-temperature gas flows through the low-temperature tube wall and is quickly cooled, these gases dissolve in the condensed water to form acidic condensed water, and the acidic condensed water will form iron scale with the metal tube wall, which will affect the heat energy recovery efficiency.

The number of water flow pipes all penetrate through the two triangular plates and the two L-shaped plates, and strip-shaped grooves are respectively opened on the outer walls of the number of arc-shaped water flow plates.

[0010] Further, the liquid storage tank part includes: A closing component, which is connected to the box body part through a closing plate slidably installed on the top of the box body part. The closing component is used to switch the flow of the magnesium hydroxide solution; Pressure relief component, the pressure relief component is connected to the box body part through a pressure relief box fixedly installed on the box body part, and the pressure relief component is used to release the air pressure in the box body part; Supplementary component, the supplementary component is connected to the liquid storage tank part through a tension spring fixedly installed on the inner wall of the bottom of the liquid storage tank part, and the supplementary component is used to continuously supplement the magnesium hydroxide solution; Among them, the closing component, the pressure relief component and the supplementary component cooperate to flexibly open and close the magnesium hydroxide solution, ensuring that the magnesium hydroxide solution will not be wasted.

[0011] Furthermore, the closing component includes a special-shaped plate fixedly installed on the top of the closing plate, including: Closing component, the closing component includes a telescopic spring fixedly installed on the liquid storage tank part, the top end of the telescopic spring is fixedly connected to the special-shaped plate, the special-shaped plate is slidably connected to the liquid storage tank part, a liquid delivery pipe is fixedly installed at the bottom of the liquid storage tank part, a liquid discharge box is fixedly installed on the right side of the water tank, several water flow pipes all penetrate through the liquid discharge box, the left ends of several arc-shaped water flow plates are fixedly connected to the liquid discharge box, the bottom end of the liquid delivery pipe extends into the box body part and communicates with the liquid discharge box, and several small holes are opened on the right side of the liquid discharge box.

[0014] Furthermore, a method for an air compressor heat energy recovery and utilization device, the method steps are as follows: S1: Interference airflow: When the gas flows through the fan blades, it will contact the flow disturbance bumps, and the flow disturbance bumps will interfere with the airflow, causing the airflow to be disordered. After the airflow enters the box body part, it will contact the inclined plate, and the inclined plate will guide the gas to several water flow pipes. Subsequently, the gas will be separated and guided to the inner wall of the box body part under the action of the triangular plate. Under the action of the L-shaped plate, the gas will be guided to several water flow pipes again. Under the action of the two groups of triangular plates, the L-shaped plate and the airflow disorder, the time of the gas in the box body part will be extended and the contact frequency between the compressed gas and the water flow pipes will be increased, so that the heat energy in the compressed gas can be recovered to the cooling water in the water flow pipes to a greater extent; S2: Slow down the flow rate: As the gas continues to be input, the air pressure inside the box body will increase. When the gas reaches the right side of the box body, it will enter the pressure relief box through several pressure relief holes. The gas will push the limit hollow plate upward. At this time, the pressure relief spring undergoes tensile deformation. After the pressure relief groove on the limit hollow plate leaves the pressure relief box, the gas inside the box body will be discharged from the pressure relief groove for pressure relief. Since the air pressure inside the box body is relatively higher and more stable than the external air pressure, the air flow rate inside the box body will be slowed down at this time, further increasing the contact time between the gas and the water pipe and improving the heat energy recovery efficiency; S3: Neutralize the condensed water: The upward movement of the limit hollow plate will drive the T-shaped plate upward, the T-shaped plate will drive the special-shaped plate upward, and the special-shaped plate will drive the closing plate. At this time, the telescopic spring undergoes tensile deformation. The magnesium hydroxide solution in the liquid storage tank part will flow into the drainage tank from the inclined surface and the liquid delivery pipe of the liquid storage tank part. The magnesium hydroxide solution will flow through the small holes onto several water pipes. Because the box body part is in an inclined state as a whole, the magnesium hydroxide solution will wrap the water pipes and move along the water pipes in the direction close to the collection box. After the compressed gas contacts the water pipes, acidic water will be condensed. The magnesium hydroxide solution will react with the acidic condensed water to neutralize it, thus preventing iron scale from forming on the water pipes; S4: Supplement the solution: The neutralized solution will flow along the inner wall of the box body after contacting the right inner wall of the box body and enter the arc-shaped water plate, and then enter the collection box along the grooves of several arc-shaped water plates and finally be discharged from the drainage pipe. As the magnesium hydroxide solution in the liquid storage tank part is discharged, the liquid level of the magnesium hydroxide solution drops and the corresponding U-shaped plate drops. The tension spring drives the T-shaped round block to drop. After the T-shaped round block leaves the liquid storage tank, the pipe connecting the liquid storage pipe will supplement the solution from the liquid storage tank into the liquid storage tank part. As the solution in the liquid storage tank part rises, the U-shaped plate will drive the T-shaped round block to close the liquid storage tank again, so that a continuous supply of solution will enter the liquid storage tank part. When the heat energy recovery stops, the corresponding limit hollow plate drops. At this time, the closing plate will drop again to block the outflow of the solution.

[0015] The present invention has the following beneficial effects: (1) For the air compressor heat energy recovery and utilization device of the present invention, the cooling water flows through the rectangular water inlet tank, the water tank and several water pipes, and then is discharged from the rectangular water outlet tank. During this process, the compressed gas of the air compressor is discharged from the circular air inlet box. When the gas passes through the cylinder, it will drive the fan blades to rotate. When the gas flows through the fan blades, it will contact the flow disturbance convex blocks. The flow disturbance convex blocks will interfere with the air flow, resulting in air flow disorder. After the air flow enters the box body part, it will contact the inclined plate. The inclined plate will guide the gas to several water pipes. Subsequently, the gas will be separated and guided to the inner wall of the box body part under the action of the triangular plate. Under the action of the L-shaped plate, the gas will be guided to several water pipes again. Under the action of the two groups of triangular plates, the L-shaped plate and the air flow disorder, the time of the gas in the box body part will be prolonged and the contact frequency between the compressed gas and the water pipes will be increased, so that the heat energy in the compressed gas can be recovered to the cooling water in the water pipes to a greater extent; (2) In a heat energy recovery and utilization device of an air compressor according to the present invention, as gas is continuously input, the air pressure inside the box body part will increase. When the gas reaches the right side of the box body part, it will enter the pressure relief box through several pressure relief holes. The gas will push the limit hollow plate to rise. At this time, the pressure relief spring undergoes tensile deformation. After the pressure relief groove on the limit hollow plate leaves the pressure relief box, the gas inside the box body part will be discharged from the pressure relief groove for pressure relief. Since the air pressure inside the box body part is relatively higher and more stable than the external air pressure, the air flow velocity inside the box body part will be slowed down at this time, further increasing the contact time between the gas and the water pipe, and improving the heat energy recovery efficiency. (3) In a heat energy recovery and utilization device of an air compressor according to the present invention, the rising of the limit hollow plate will drive the T-shaped plate to rise, the T-shaped plate will drive the special-shaped plate to rise, and the special-shaped plate drives the closing plate. At this time, the telescopic spring undergoes tensile deformation. The magnesium hydroxide solution in the liquid storage tank part will flow from the inclined surface and the liquid delivery pipe of the liquid storage tank part into the liquid discharge box. The magnesium hydroxide solution will flow through the small holes onto several water pipes. Because the box body part is in an inclined state as a whole, the magnesium hydroxide solution will wrap the water pipes and move along the water pipes in the direction close to the collection box. After the compressed gas contacts the water pipes, acidic water will be condensed. The magnesium hydroxide solution will react with the acidic condensed water to neutralize, thereby preventing iron scale from forming on the water pipes and ensuring that the water pipes can conduct heat normally and stably recover the heat energy. (4) In a heat energy recovery and utilization device of an air compressor according to the present invention, the neutralized solution will flow along the inner wall to the arc-shaped water plate after contacting the right inner wall of the box body part, and then enter the collection box along the grooves of several arc-shaped water plates and finally be discharged from the drain pipe. As the magnesium hydroxide solution in the liquid storage tank part is discharged, the liquid level of the magnesium hydroxide solution drops, and the corresponding C-shaped plate drops. The tension spring drives the T-shaped round block to drop. After the T-shaped round block leaves the liquid storage tank, the pipeline connecting the liquid storage pipe will replenish the solution from the liquid storage tank into the liquid storage tank part. As the solution in the liquid storage tank part rises, the C-shaped plate will drive the T-shaped round block to close the liquid storage tank again, so that a continuous supply of solution will enter the liquid storage tank part. When the heat energy recovery stops, the corresponding limit hollow plate drops, and at this time, the closing plate will drop again to block the outflow of the solution.

[0016] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Please refer to Figure 1 - Figure 8 As shown, the present invention is an air compressor heat energy recovery and utilization device, including a box body part 1, the box body part 1 has an installation structure space, and the box body part 1 is placed obliquely as a whole; A liquid storage tank part 2, the liquid storage tank part 2 is arranged above the box body part 1, and the liquid storage tank part 2 is used for discharging the magnesium hydroxide solution to neutralize the condensed acidic water; Among them, the cooperation between the box body part 1 and the liquid storage tank part 2 can reduce the possibility of iron scale formation due to condensed acidic water in the box body part 1, thereby ensuring the efficiency of heat energy recovery.

[0022] As Figure 2 shown, the box body part 1 includes: A turbulence component, which is connected to the box body part 1 through a rectangular water inlet tank 101 fixedly installed on the left side of the box body part 1. The turbulence component is used to interfere with the compressed gas entering the box body part 1, so as to increase the time of the gas in the box body part 1; A flow guiding component, which is connected to the box body part 1 through a water tank 107 fixedly installed in the box body part 1. The flow guiding component is used to guide the compressed air entering the box body part 1 to further extend the staying time in the box body part 1; A collection component, which is connected to the box body part 1 through a rectangular water outlet tank 111 fixedly installed on the right side of the box body part 1. The collection component is used to collect the condensed water after the neutralization reaction; Among them, the cooperation of the turbulence component, the flow guiding component and the collection component can extend the time of the compressed air in the box body part 1, so that the heat energy recovery rate reaches the maximum.

[0023] By setting the cooperation of the turbulence component, the flow guiding component and the collection component, the time of the compressed air in the box body part 1 can be extended, so that the heat energy recovery rate reaches the maximum.

[0024] As Figure 2 and Figure 4 shown, the turbulence component includes a circular air inlet box 102 fixedly installed on the left side of the rectangular water inlet tank 101; A turbulence component, which includes a plurality of cylinders 103 penetrating and installed on the rectangular water inlet tank 101 and the circular air inlet box 102. A cross 104 is fixedly installed in each of the plurality of cylinders 103, and a plurality of fan blades 105 are rotatably installed on each of the plurality of crosses 104. A turbulence bump 106 is fixedly installed on each of the plurality of fan blades 105.

[0025] When the gas passes through the cylinder 103, it will drive the fan blade 105 to rotate. When the gas flows through the fan blade 105, it will contact the turbulence bump 106, and the turbulence bump 106 will interfere with the air flow, resulting in air flow disorder.

[0026] As Figure 2 shown, the flow guiding component includes inclined plates 108 fixedly installed on the inner walls of the top and bottom of the box body part 1, including: A flow guiding component, which includes two triangular plates 109 and two L-shaped plates 110 fixedly installed in the box body part 1. The right ends of the plurality of cylinders 103 all extend into the box body part 1, and the rectangular water inlet tank 101 is communicated with the water tank 107.

[0027] The inclined plate 108 will direct the gas to a number of water pipes 112, and then the gas will be separately directed to the inner wall of the box body part 1 under the action of the triangular plate 109.

[0028] As Figure 2 and Figure 5 shown, the collection assembly includes a rectangular water outlet tank 111 fixedly installed on the right side of the box body part 1. The collection assembly includes a number of water pipes 112 fixedly installed on the right side of the water tank 107, including: The collection assembly, which includes a number of arc-shaped water flow plates 113 fixedly installed on the right inner wall of the box body part 1. A collection box 114 is fixedly installed on the bottom inner wall of the box body part 1. A number of drain pipes 115 are opened on the right side of the collection box 114. A number of water pipes 112 all penetrate through two triangular plates 109 and two L-shaped plates 110. Strip-shaped grooves are respectively opened on the outer walls of a number of arc-shaped water flow plates 113.

[0029] Under the action of the L-shaped plate 110, the gas will be directed to a number of water pipes 112 again. Under the action of two groups of triangular plates 109 and L-shaped plates 110 and the air flow disorder, the time of the gas in the box body part 1 will be extended and the contact frequency between the compressed gas and the water pipes 112 will be increased, so that the heat energy in the compressed gas can be recovered to the cooling water in the water pipes 112 to a greater extent.

[0030] As Figure 5 and Figure 7 shown, the liquid storage tank part 2 includes: The closing assembly, which is connected to the box body part 1 through a closing plate 201 slidably installed on the top of the box body part 1. The closing assembly is used to switch the flow of the magnesium hydroxide solution; The pressure relief assembly, which is connected to the box body part 1 through a pressure relief box 206 fixedly installed on the box body part 1. The pressure relief assembly is used to release the air pressure in the box body part 1; The replenishment assembly, which is connected to the liquid storage tank part 2 through a tension spring 212 fixedly installed on the bottom inner wall of the liquid storage tank part 2. The replenishment assembly is used to continuously replenish the magnesium hydroxide solution; Among them, the closing assembly, the pressure relief assembly and the replenishment assembly cooperate to flexibly switch the magnesium hydroxide solution, ensuring that the magnesium hydroxide solution will not be wasted.

[0031] By setting the cooperation of the closing assembly, the pressure relief assembly and the replenishment assembly, the magnesium hydroxide solution can be flexibly switched, ensuring that the magnesium hydroxide solution will not be wasted.

[0032] As Figure 2 、 Figure 4 and Figure 5 shown, the closing assembly includes a special-shaped plate 202 fixedly installed on the top of the closing plate 201, including: Closing assembly, the closing assembly includes a telescopic spring 203 fixedly installed on the liquid storage tank part 2. The top end of the telescopic spring 203 is fixedly connected to the special-shaped plate 202. The special-shaped plate 202 is slidably connected to the liquid storage tank part 2. A liquid infusion pipe 204 is fixedly installed at the bottom of the liquid storage tank part 2. A liquid discharge tank 205 is fixedly installed on the right side of the water tank 107. A plurality of water pipes 112 all penetrate through the liquid discharge tank 205. The left ends of a plurality of arc-shaped water plates 113 are all fixedly connected to the liquid discharge tank 205. The bottom end of the liquid infusion pipe 204 extends into the box body part 1 and communicates with the liquid discharge tank 205. A plurality of small holes 2051 are formed in the right side of the liquid discharge tank 205.

[0033] The special-shaped plate 202 drives the closing plate 201. At this time, the telescopic spring 203 undergoes a tensile deformation, and the magnesium hydroxide solution in the liquid storage tank part 2 will flow into the liquid discharge tank 205 from the inclined surface of the liquid storage tank part 2 and the liquid infusion pipe 204.

[0034] As Figure 7 shown, the pressure relief assembly includes a limit hollow plate 207 slidably installed in the pressure relief box 206, including: The pressure relief assembly, the pressure relief assembly includes a pressure relief spring 208 fixedly installed on the inner wall of the top of the limit hollow plate 207. The bottom end of the pressure relief spring 208 is fixedly connected to the inner wall of the bottom of the pressure relief box 206. A plurality of pressure relief holes 209 are formed in the bottom of the pressure relief box 206. A plurality of pressure relief grooves 210 are formed in the outer wall of the limit hollow plate 207. A T-shaped plate 211 is fixedly installed on the top of the limit hollow plate 207.

[0035] The rising of the limit hollow plate 207 will drive the T-shaped plate 211 to rise. The T-shaped plate 211 will drive the special-shaped plate 202 to rise. The special-shaped plate 202 drives the closing plate 201. At this time, the telescopic spring 203 undergoes a tensile deformation, and the magnesium hydroxide solution in the liquid storage tank part 2 will flow into the liquid discharge tank 205 from the inclined surface of the liquid storage tank part 2 and the liquid infusion pipe 204. The magnesium hydroxide solution will flow from the small holes 2051 to a plurality of water pipes 112. Because the box body part 1 is in an inclined state as a whole, the magnesium hydroxide solution will wrap the water pipes 112 and move along the water pipes 112 in the direction close to the collection box 114. After the compressed gas contacts the water pipes 112, acidic water will be condensed. The magnesium hydroxide solution will react with the acidic condensed water to avoid the generation of iron scale on the water pipes 112, ensuring that the water pipes 112 can conduct heat normally and stably recover the heat energy.

[0036] As Figure 5 shown, the replenishment assembly includes a U-shaped plate 213 fixedly installed at the top end of the pull spring 212, including: Supplementary component, the supplementary component includes a liquid storage pipe 214 fixedly installed on the liquid storage tank part 2, the U-shaped plate 213 is slidably connected to the liquid storage tank part 2, a T-shaped round block 215 is slidably installed in the liquid storage pipe 214, the bottom end of the T-shaped round block 215 is fixedly connected to the U-shaped plate 213, and a plurality of liquid storage grooves 216 are formed on the outer wall of the liquid storage pipe 214.

[0037] When the liquid level of the magnesium hydroxide solution drops, the corresponding U-shaped plate 213 drops, the tension spring 212 drives the T-shaped round block 215 to drop. After the T-shaped round block 215 leaves the liquid storage groove 216, the pipe connecting the liquid storage pipe 214 will replenish the solution from the liquid storage groove 216 into the liquid storage tank part 2. As the solution in the liquid storage tank part 2 rises, the U-shaped plate 213 will drive the T-shaped round block 215 to close the liquid storage groove 216 again, so that a continuous supply of solution will enter the liquid storage tank part 2. When the heat energy recovery stops, the corresponding limit hollow plate 207 drops, and at this time the closing plate 201 will drop again to block the outflow of the solution.

[0038] As Figure 1 - 8 shown, a method for a heat energy recovery and utilization device of an air compressor, the method steps are as follows: S1: Interfere with the air flow: When the gas flows through the fan blade 105, it will contact the flow disturbance convex block 106. The flow disturbance convex block 106 will interfere with the air flow, resulting in air flow disorder. After the air flow enters the box body part 1, it will contact the inclined plate 108. The inclined plate 108 will guide the gas to a plurality of water pipes 112. Subsequently, the gas will be separated and guided to the inner wall of the box body part 1 under the action of the triangular plate 109. Under the action of the L-shaped plate 110, the gas will be guided to a plurality of water pipes 112 again. Under the action of the two groups of triangular plates 109 and L-shaped plates 110 and the air flow disorder, the time of the gas in the box body part 1 will be extended and the contact frequency between the compressed gas and the water pipes 112 will be increased, so that the heat energy in the compressed gas can be recovered to the cooling water in the water pipes 112 to a greater extent; S2: Slow down the flow rate: As the gas is continuously input, the air pressure in the box body part 1 will increase. When the gas reaches the right side of the box body part 1, it will enter the pressure release box 206 through a plurality of pressure release holes 209. The gas will push the limit hollow plate 207 to rise. At this time, the pressure release spring 208 undergoes a tensile deformation. After the pressure release groove 210 on the limit hollow plate 207 leaves the pressure release box 206, the gas in the box body part 1 will be discharged from the pressure release groove 210 for pressure release. Since the air pressure in the box body part 1 is relatively high and stable compared with the external air pressure, the air flow rate in the box body part 1 will be slowed down at this time, further increasing the contact time between the gas and the water pipes 112 and improving the heat energy recovery efficiency; S3: Neutralize the condensed water: When the limiting hollow plate 207 rises, it will drive the T-shaped plate 211 to rise. The T-shaped plate 211 will drive the special-shaped plate 202 to rise, and the special-shaped plate 202 will drive the closing plate 201. At this time, the telescopic spring 203 undergoes tensile deformation. The magnesium hydroxide solution in the liquid storage tank part 2 will flow into the drainage tank 205 from the inclined surface of the liquid storage tank part 2 and the liquid delivery pipe 204. The magnesium hydroxide solution will flow onto a number of water pipes 112 through the small holes 2051. Since the whole of the box body part 1 is in an inclined state, the magnesium hydroxide solution will wrap the water pipes 112 and move along the water pipes 112 in the direction close to the collection box 114. When the compressed gas contacts the water pipes 112, acidic water will be condensed. The magnesium hydroxide solution will react with the acidic condensed water to avoid the formation of iron scale on the water pipes 112; S4: Supplement the solution: The neutralized solution will flow along the inner wall of the right side of the box body part 1 and into the arc-shaped water plate 113, and then enter the collection box 114 along the grooves of a number of arc-shaped water plates 113 and finally be discharged from the drain pipe 115. As the magnesium hydroxide solution in the liquid storage tank part 2 is discharged, the liquid level of the magnesium hydroxide solution drops, and the corresponding C-shaped plate 213 drops. The tension spring 212 drives the T-shaped round block 215 to drop. After the T-shaped round block 215 leaves the liquid storage tank 216, the pipe connecting the liquid storage pipe 214 will supplement the solution from the liquid storage tank 216 into the liquid storage tank part 2. As the solution in the liquid storage tank part 2 rises, the C-shaped plate 213 will drive the T-shaped round block 215 to close the liquid storage tank 216 again, so that a continuous supply of solution will enter the liquid storage tank part 2. When the heat energy recovery stops, the corresponding limiting hollow plate 207 drops. At this time, the closing plate 201 will drop again to block the outflow of the solution.

10. A method for using an air compressor heat recovery device, using the air compressor heat recovery device as claimed in claim 9, characterized in that: The method steps are as follows: S1: Interference airflow: When the gas flows through the fan blade (105), it will contact the flow disturbance bump (106), and the flow disturbance bump (106) will interfere with the airflow, resulting in airflow disorder. After the airflow enters the box body part (1), it will contact the inclined plate (108), and the inclined plate (108) will guide the gas to a plurality of water pipes (112). Subsequently, the gas will be separately guided to the inner wall of the box body part (1) under the action of the triangular plate (109). Under the action of the L-shaped plate (110), the gas will be guided to a plurality of water pipes (112) again. Under the action of the two groups of triangular plates (109) and L-shaped plates (110) and the airflow disorder, the time of the gas in the box body part (1) will be extended and the contact frequency between the compressed gas and the water pipes (112) will be increased, so that the heat energy in the compressed gas can be recovered to the cooling water in the water pipes (112) to a greater extent; S2: Slow down the flow rate: As the gas is continuously input, the air pressure in the box body part (1) will increase. When the gas reaches the right side of the box body part (1), it will enter the pressure relief box (206) through a plurality of pressure relief holes (209). The gas will push the limit hollow plate (207) to rise. At this time, the pressure relief spring (208) undergoes tensile deformation. After the pressure relief groove (210) on the limit hollow plate (207) leaves the pressure relief box (206), the gas in the box body part (1) will be discharged from the pressure relief groove (210) for pressure relief. Since the air pressure in the box body part (1) is relatively higher and more stable than the external air pressure, the air flow rate in the box body part (1) will be slowed down at this time, further increasing the contact time between the gas and the water pipes (112) and improving the heat energy recovery efficiency; S3: Neutralize the condensed water: The rise of the limit hollow plate (207) will drive the T-shaped plate (211) to rise, the T-shaped plate (211) will drive the special-shaped plate (202) to rise, and the special-shaped plate (202) will drive the closing plate (201). At this time, the telescopic spring (203) undergoes tensile deformation. The magnesium hydroxide solution in the liquid storage tank part (2) will flow into the drainage tank (205) from the inclined surface and the infusion pipe (204) of the liquid storage tank part (2). The magnesium hydroxide solution will flow to a plurality of water pipes (112) through the small holes (2051). Because the box body part (1) is in an inclined state as a whole, the magnesium hydroxide solution will wrap the water pipes (112) and move along the water pipes (112) in the direction close to the collection box (114). After the compressed gas contacts the water pipes (112), acidic water will be condensed. The magnesium hydroxide solution will react with the acidic condensed water to avoid the formation of iron scale on the water pipes (112); S4: Replenishing solution: The neutralized solution will flow into the arc-shaped water flow plate (113) along the inner wall after contacting the right inner wall of the box body (1), and then enter the collection box (114) along the grooves of several arc-shaped water flow plates (113) and finally be discharged from the drain pipe (115). As the magnesium hydroxide solution in the liquid storage box (2) is discharged, the liquid level of the magnesium hydroxide solution drops, the corresponding T-shaped plate (213) drops, and the tension spring (212) drives the T-shaped round block (215) to drop, and the T-shaped round block (215) After leaving the liquid storage tank (216), the pipe connected to the liquid storage pipe (214) will replenish the solution from the liquid storage tank (216) to the liquid storage tank portion (2). As the solution in the liquid storage tank portion (2) rises, the T-shaped plate (213) will drive the T-shaped round block (215) to close the liquid storage tank (216) again, so that a continuous flow of solution will enter the liquid storage tank portion (2). When the heat recovery stops, the corresponding limit hollow plate (207) drops, and at this time the closing plate (201) will drop again to block the outflow of the solution.
