In this invention, a driving mechanism is set to drive the gas distribution plate to move, and the rotating characteristics of the rotating plate are used to adjust several hoses originally distributed horizontally to a twisted state, so that the water heated by the internal water body itself can be changed, while the contact heat is maintained constant, so that the rapid heating of the water body and the rapid cooling of the gas can be achieved, so that when the temperature is low in winter, the water temperature meets the requirements, and when the temperature is high in summer, the gas temperature can also be quickly reduced to ensure the normal use of the air compressor.

[0004] Although the above patent improves the heat exchange efficiency by using a movable and rotatable hose, the air compressor waste heat utilization equipment on the market mainly relies on traditional heat exchange methods to achieve the purpose of heating the fluid. In the traditional heat exchange method, a medium that forms a path between the heat-containing gas and the fluid medium is required to separate the two. Therefore, the contact area between the fluid and the heat-containing gas is always greatly limited, which directly leads to the difficulty in making breakthrough progress in the effect of the fluid absorbing heat.

[0015] Preferably, the outer surface of the water tank is fixedly connected with a first flange pipe and a second flange pipe at a position below the annular filter plate, a heater is installed at the bottom of the first flange pipe, a temperature sensor is installed at the bottom of the second flange pipe, and the heating end of the heater and the detection end of the temperature sensor both extend into the interior of the water tank, and a drain pipe is fixedly connected near the middle position of the bottom of the water tank, and a valve for controlling opening and closing is installed on the outside of the drain pipe.

[0016] A method for using a surround-type air compressor waste heat recycling device comprises the following steps: S1. During use, connect the upper left input pipe to the gas pipeline that needs to be cooled and filtered by the surround air compressor, then connect the upper right input pipe to the water inlet pipeline to transport the water to be heated, and connect the lower left input pipe to the exhaust pipe of the air compressor; S2. When low-temperature water is inputted from the upper right input pipe and enters the second shell, it will be retained in the interlayer formed by the two upper partitions. With the injection of water flow, the water will enter the inside of the through-tube through the inner inclined holes on the surface of the upper half of the through-tube and flow downward. The heat-containing gas inputted from the upper left input pipe will enter the interlayer formed between the two lower partitions and enter the inside of the through-tube through the inner inclined holes on the surface of the lower half of the through-tube. Under the action of the inner inclined holes, both water and gas enter the inside of the through-tube in the form of jets, and the inner inclined holes distributed spirally downward also cause the water flow and gas to rotate downward at high speed inside the through-tube. S3. The water and gas discharged from the through-tube will form a rotating water film under the action of centrifugal force. Multiple adjacent water films will merge under the action of fluid tension and viscosity, thus forming a large-area water film. S4. Then the water film falls on the water layer formed by the triangular plates in the water sprinkling component, where it will gather and form a uniform water curtain from the gap and flow downward. After a large amount of water curtain formed by the water sprinkling component falls downward, it will sprinkle on the microporous plate in the second heat exchange component. The water will be sucked into the microporous plate and flow downward through the dense micropores inside. The lower input pipe transports the compressed gas with a higher temperature into the second shell, where it will flow upward and mix with the water in different states above.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This equipment converts water into a large-area water film, and then uses the water spray component booster to convert it into a water curtain. During the process, the internal plane space of the equipment is fully filled by the water spray component booster and the water curtain. After passing through the microporous plate, the water curtain fills the internal plane space of the equipment again and reduces the flow rate. In this process, the surround air compressor compresses the air and water for three heat exchanges, ensuring that the waste heat can be fully utilized. The heat that needs to be cooled by the conventional air compressor is introduced into this equipment for the first heat exchange, which improves the waste heat utilization effect. The gas and liquid are not separated by other media. The gas-liquid direct mixing and separation method breaks through the problem of large limitations on the contact area in the gas-liquid heat exchange process, thereby greatly improving the effect of fluid absorbing heat; 2. When in use, when the input pipe transports gas and liquid from the outside to the inside of the booster of the containment component, under the action of pressure, when the gas and liquid pass through the inner side of the shrink ring inside the input pipe, they will generate inward pressure on the block and force the block to move inward and squeeze the spring to shrink. At this time, a gap for gas and liquid to pass through is generated between the block and the shrink ring. When the gas and liquid are stopped from being transported, the block loses the squeezing force, and the spring rebounds to drive the block to reset and block the shrink ring from the inside to prevent the internal gas and liquid from being discharged. There is no need to control it through a control valve, which reduces the difficulty of operation and improves the use effect. 3. During use, after the water that has completed heat exchange enters the water tank, the annular filter plate can effectively prevent impurities in the heated water mixed with gas from entering the water tank, and has a filtering effect. When the heated water in the water tank needs to be used, the heated water can be discharged for use by opening the drain pipe through the valve, and the temperature sensor continuously monitors the water temperature in the water tank. When higher temperature water is needed, it can be directly heated again by the heater, and the water temperature can be increased by consuming a small amount of electricity, thereby increasing the adaptability of hot water and reducing the limitations of water heated by the waste heat of the air compressor due to limited temperature.

[0021] Reference Figure 1-Figure 9 As shown: A surround-type air compressor waste heat recycling device, comprising: a storage mechanism 1 and a waste heat utilization mechanism, wherein the waste heat utilization mechanism is arranged on the top of the storage mechanism 1 and is composed of a containing component 2, a gas-liquid input component 3, a first heat exchange component 5, a water sprinkling component 6 and a second heat exchange component 7, the number of gas-liquid input components 3 is set to three, and two of the gas-liquid input components 3 are arranged at the left side of the outside of the containing component 2 for inputting air compressor waste heat, and the other gas-liquid input component 3 is arranged at the right side of the outside of the containing component 2 near the top for inputting liquid, the gas-liquid input component 3 includes an input pipe 301 for inputting gas and liquid, the first heat exchange component 5 is arranged at a position between the two gas-liquid input components 3 above the inside of the containing component 2 and is composed of three partition plates 501 and a plurality of through pipes 503, and a plurality of inner inclined holes 504 are opened on the surface of the through pipe 503, the water sprinkling component 6 is arranged at a position below the first heat exchange component 5 inside the containing component 2 for re-aggregating the liquid, and the second heat exchange component 7 is arranged at a position below the water sprinkling component 6 inside the containing component 2 for secondary heat exchange between gas and liquid.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the containing assembly 2 is composed of a first shell 201 and a second shell 202, the second shell 202 is fixedly connected to the top of the first shell 201 and the two are in a connected state, the bottoms of the first shell 201 and the second shell 202 are both straight-cylindrical and the tops are conical, and the top of the second shell 202 is provided with an exhaust port 203, wherein two input pipes 301 are respectively fixedly connected to the two sides of the second shell 202 and the upper and lower positions are staggered, and the other input pipe 301 is fixedly connected to the outer surface of the first shell 201, and a supercharger 204 is installed on the top of the second shell 202, and the input port of the supercharger 204 and the exhaust port 203 are fixedly connected; the first shell 201 and the second shell 202 are composed of The formed containing component 2 is mainly used to contain the first heat exchange component 5, the water sprinkling component 6 and the second heat exchange component 7 inside, and the inside and outside of the containing component 2 are connected through the gas-liquid input component 3. The exhaust port 203 is used to discharge the gas input into the device, and it is pressurized by the supercharger 204 to ensure that the air pressure value is sufficient to meet the use requirements. During use, the upper left input pipe 301 is connected to the gas pipeline that needs to be cooled and filtered by the surround air compressor, and then the upper right input pipe 301 is connected to the water inlet pipeline to transport the water to be heated, which is the same as the connection method of conventional air compressor waste heat utilization equipment on the market, and the lower left input pipe 301 is connected to the air compressor exhaust pipe.

[0023] like Figure 2 , Figure 4 and Figure 5As shown, three partition plates 501 are fixedly connected to the inner surface wall of the first shell 201 at equal distances, and the three partition plates 501 form two interlayers corresponding to the two upper input pipes 301, and multiple through-tubes 503 are fixedly connected between the insides of the three partition plates 501, and the two ends extend upward and downward respectively, and the inner inclined holes 504 are inclined inwardly and downwardly, and the multiple inner inclined holes 504 are spirally arranged on the outer surface of the through-tube 503 to connect the inner side and the outer side of the through-tube 503, and the top and bottom of the partition plate 501 are located on the outer side of the through-tube 503. The position is fixedly connected with a sealing ring 502, and the inner wall of the sealing ring 502 and the outer wall of the through-tube 503 are tightly fitted to improve the sealing of the interlayer; when the upper right input pipe 301 inputs low-temperature water into the second shell 202, it will be retained in the upper two partitions. In the interlayer formed by the plate 501, as the water flow is injected, the water will enter the inside of the through-tube 503 through the inner inclined hole 504 on the upper half surface of the through-tube 503 and flow downward, and the heat-containing gas input by the upper left input pipe 301 will enter the interlayer formed between the two partition plates 501 below, and enter the inside of the through-tube 503 through the inner inclined hole 504 on the lower half surface of the through-tube 503. Under the action of the inner inclined hole 504, both the water and the gas enter the inside of the through-tube 503 in the form of jets, and the inner inclined holes 504 distributed spirally downward also cause the water flow and the gas to rotate downward at a high speed in the through-tube 503. In this process, the low-temperature water and the heat-containing gas will produce a violent mixing heating effect when they rotate downward at a high speed in the through-tube 503, so that the heat in the gas is efficiently transferred to the water for heating.

[0024] like Figure 2 , Figure 4 and Figure 7As shown, the water spraying assembly 6 is composed of a connecting ring 601 and a plurality of triangular plates 602. The connecting ring 601 is fixedly connected to the inner surface wall of the second housing 202. The triangular plates 602 are fixedly connected to the inner surface wall of the connecting ring 601 and are provided with six layers in total. Gaps are reserved between the triangular plates 602 adjacent to each other in the upper and lower directions, and the positions of the triangular plates 602 in the upper and lower positions are staggered. The water and air discharged downward from the through-tube 503 will form a rotating water film under the action of centrifugal force when discharged. Multiple adjacent water films will merge under the action of fluid tension and viscosity, thereby forming a large-area water film. When the lower input pipe 301 receives the air discharged from the exhaust pipe of the surround air compressor, since the air compressed by the air compressor has a higher temperature when not cooled, the water film will be in direct and full contact with the air discharged from below and moving upward, thereby quickly and effectively absorbing the heat in the air discharged from the air compressor. The water film then falls on the water sprinkling layer formed by the triangular plate 602 in the water sprinkling assembly 6, where it will gather and form a uniform water curtain from the gap that flows downward. In this process, the gas discharged from below will be in full contact with the water flow in the gap of the triangular plate 602 when it flows upward, and will directly heat the water quickly.

[0025] like Figure 2 , Figure 4 and Figure 8 As shown, the second heat exchange component 7 includes a support ring 701, which is fixedly connected between the inner surface walls of the second shell 202, and a microporous plate 702 is placed inside the support ring 701, and a mounting ring 703 is fixedly connected to the top of the support ring 701, and the bottom of the mounting ring 703 is in conflict with the top of the microporous plate 702. The bottom of the support ring 701 and the top of the mounting ring 703 are both provided with a plurality of pressure strips for shaping the microporous plate 702; the support ring 701 is used to accommodate the microporous plate 702, and the mounting ring 703 cooperates with the support ring 701 to fix the microporous plate 702, and the microporous plate 702 is made of a sponge-like material and has a large number of micropores inside. After a large amount of water curtains are formed by the water spraying component 6, the water will fall down and will be sprinkled on the microporous plate 702 in the second heat exchange component 7, and the water flow will be sucked into the microporous plate 702 and flow downward through the densely distributed micropores inside, and the gas input from the bottom will directly contact the water in the micropores when flowing upward, thereby performing efficient heat exchange with the water.

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Fig. 9As shown, a mounting bracket 302 is fixedly connected to the inner wall of the input pipe 301 near the inner side, a spring 303 is fixedly connected to the outer side of the mounting bracket 302, a blocking block 304 is fixedly connected to one end of the outer side of the spring 303, and the end of the blocking block 304 near the outer side is round-headed, a shrinking ring 306 is fixedly connected to the inner wall of the input pipe 301 near the outer side, the middle position of the inner wall of the shrinking ring 306 is arc-shaped and shrinks, and the shrinking ring 306 and the blocking block 304 cooperate to block the input pipe 301, and a sliding rod 305 is fixedly connected to the blocking block 304 near the inner side, and the end of the sliding rod 305 slides through the outer surface of the mounting bracket 302 and extends inward; when the input pipe 301 transports gas and liquid from the outside to the inside of the containing component 2, Under the action of pressure, when the gas and liquid pass through the inner side of the shrinkage ring 306 inside the input pipe 301, inward pressure will be generated on the block 304, forcing the block 304 to move inward and squeeze the spring 303 to shrink. At this time, a gap is generated between the block 304 and the shrinkage ring 306 for the passage of gas and liquid. When the delivery of gas and liquid stops, the block 304 loses the squeezing force, and the rebound of the spring 303 can drive the block 304 to reset and block the shrinkage ring 306 from the inside to prevent the internal gas and liquid from being discharged. There is no need to control it through a control valve, which reduces the difficulty of operation and improves the use effect. When the block 304 is moving, the slide rod 305 slides inside the mounting frame 302, which plays a role in limiting the block 304 and allows it to move stably in a straight line.

[0027] like Figure 1-Figure 3 As shown, the storage mechanism 1 includes a horizontal water tank 101, the top of the water tank 101 is fixedly connected with a connecting pipe 102, the top of the connecting pipe 102 is fixedly connected with the bottom of the second shell 202, an annular filter plate 103 is fixedly connected between the inner top and the inner bottom of the water tank 101, the annular filter plate 103 and the connecting pipe 102 are arranged concentrically and the inner diameter of the annular filter plate 103 is larger than the inner diameter of the connecting pipe 102, and the top of the water tank 101 is symmetrically fixedly connected with a support frame 104 near the edges of both sides; the water that effectively absorbs the heat in the gas and is heated will enter the water tank 101 through the first shell 201 and the connecting pipe 102 under the action of gravity for storage, and the annular filter plate 103 in the water tank 101 plays a role in separating the heated water injected from the top and the water tank 101, and the design structure is simple, which can effectively prevent impurities in the heated water mixed with the gas from entering the water tank 101, and has a filtering effect.

[0028] like Figure 1-Figure 3As shown, the outer surface of the water tank 101 is located below the annular filter plate 103 and is fixedly connected with a first flange pipe 105 and a second flange pipe 107. A heater 106 is installed at the bottom of the first flange pipe 105, and a temperature sensor 108 is installed at the bottom of the second flange pipe 107. The heating end of the heater 106 and the detection end of the temperature sensor 108 both extend into the water tank 101. A drain pipe 109 is fixedly connected to the bottom of the water tank 101 near the middle position. A valve 110 for controlling opening and closing is installed on the outside of the drain pipe 109. The support frame 104 is used to support the device. The first flange pipe 105 is installed with a heater 106 at the bottom, and a temperature sensor 108 is installed at the bottom of the second flange pipe 107. The heater 106 and the detection end of the temperature sensor 108 are both extended to the inside of the water tank 101. The pipe 105 and the second flange pipe 107 are used to install the heater 106 and the temperature sensor 108. When the heated water in the water tank 101 needs to be used, the heated water can be discharged for use by opening the drain pipe 109 through the valve 110, and the temperature sensor 108 continuously monitors the water temperature in the water tank 101. When higher temperature water is needed, it can be directly heated again by the heater 106, and the water temperature can be increased by consuming a small amount of electricity, thereby increasing the adaptability of hot water and reducing the limitations of water heated by the waste heat of the air compressor due to limited temperature.

[0029] In the present invention, during use, the upper left input pipe 301 is connected to the gas pipeline that needs to be cooled and filtered by the surround air compressor, and then the upper right input pipe 301 is connected to the water inlet pipeline to transport the water to be heated, which is the same as the connection method of conventional air compressor waste heat utilization equipment on the market, and the lower left input pipe 301 is connected to the air compressor exhaust pipe. When the upper right input pipe 301 inputs low-temperature water into the second shell 202, it will be retained in the interlayer formed by the upper two partition plates 501. With the injection of water flow, water will enter the inside of the through-tube 503 through the inner inclined hole 504 on the upper half of the surface of the through-tube 503 and flow downward, and the heat-containing gas input by the upper left input pipe 301 will enter the two partition plates below. The water and gas enter the interlayer formed between 501 and enter the inside of the through-tube 503 through the inner inclined hole 504 on the lower half surface of the through-tube 503. Under the action of the inner inclined hole 504, both water and gas enter the inside of the through-tube 503 in the form of jets, and the inner inclined holes 504 distributed spirally downward also cause the water flow and gas to rotate downward at high speed inside the through-tube 503. In this process, the low-temperature water and the heat-containing gas will produce a violent mixing and heating effect during the high-speed downward rotation inside the through-tube 503, thereby efficiently transferring the heat in the gas to the water for heating. The water and gas rotating downward from the through-tube 503 will form a rotating water film under the action of centrifugal force when discharged, and multiple close water films will occur under the action of fluid tension and viscosity. The water film will then fall on the water layer formed by the triangular plate 602 in the water sprinkling component 6, where it will gather and form a uniform water curtain that flows downward from the gap. After a large amount of water curtains are formed by the water sprinkling component 6, the water will fall onto the microporous plate 702 in the second heat exchange component 7. The water will be sucked into the microporous plate 702 and flow downward through the densely distributed micropores inside. The compressed gas discharged from the compressor and input through the lower input pipe 301 has a higher temperature. After entering the second shell 202, it will flow upward. When the high-temperature compressed gas passes through the micropores on the surface of the microporous plate 702, it will be fully mixed with the water filling the micropores, thereby quickly transferring heat to the water. Subsequently, after a heat exchange and after the temperature drops, the compressed gas will mix with the microporous plate 702 again. The water forming the water curtain in the gap of the triangular plate 602 undergoes secondary heat exchange, thereby transferring the residual heat to the water curtain, and then when passing through the water film formed under the through-tube 503, the residual heat is transferred to the water film, and finally it is pressurized by the supercharger 204 on the exhaust port 203 at the top of the second shell 202 and discharged for use. Compared with the traditional surround-type air compressor waste heat utilization equipment, this equipment converts water into a large-area water film, and then uses the water sprinkling component 6 to convert it into a water curtain. During the process, the plane space inside the equipment is fully filled with the water sprinkling component 6 and the water curtain. After passing through the microporous plate 702, the water curtain fills the plane space inside the equipment again and reduces the flow rate. In this process, the surround-type air compressor compresses air and water and performs three heat exchanges at the stage, ensuring that the waste heat can be fully utilized.And by introducing the heat that needs to be cooled by the conventional air compressor into this equipment for the first heat exchange, the waste heat utilization effect is improved, and the gas and liquid are not separated by other media. The gas and liquid are directly mixed and then separated, which breaks through the problem of large limitations in the contact area during the gas-liquid heat exchange process, thereby greatly improving the effect of the fluid absorbing heat. When the input pipe 301 transports gas and liquid from the outside to the inside of the containing component 2, under the action of pressure, when the gas and liquid pass through the inner side of the shrinkage ring 306 inside the input pipe 301, an inward pressure is generated on the block 304 and the block 304 is forced to move inward and squeeze the spring 303 to shrink. At this time, a gap is generated between the block 304 and the shrinkage ring 306 for gas and liquid to pass through. When the gas and liquid are stopped, the block 304 loses the squeezing force, and the spring 303 rebounds to drive the block 304 to reset and block the shrinkage ring 306 from the inside, thereby preventing the internal gas and liquid from being discharged, and there is no need to control it through a control valve. The operation difficulty is reduced and the use effect is improved. At the same time, the water that effectively absorbs the heat in the gas and is heated will enter the water tank 101 for storage through the first shell 201 and the connecting pipe 102 under the action of gravity, and the annular filter plate 103 in the water tank 101 plays the role of separating the heated water injected from the top and the water tank 101. The design structure is simple and can effectively prevent impurities in the heated water mixed with the gas from entering the water tank 101, and has a filtering effect. When the heated water in the water tank 101 needs to be used, the heated water can be discharged for use by opening the drain pipe 109 through the valve 110, and the temperature sensor 108 continuously monitors the water temperature in the water tank 101. When higher temperature water is needed, it can be directly heated again by the heater 106, and the water temperature can be increased by consuming a small amount of electricity, thereby increasing the adaptability of hot water and reducing the limitations of water heated by the waste heat of the air compressor due to the limited temperature.
