Description

Technical Field

[0001] This application relates to the field of air compressor energy-saving technology, and in particular to an energy-saving circulation device for an air compressor station. Background Technology

[0002] Air compressor stations, as key power supply facilities in industrial production, convert electrical energy into the potential energy of compressed air through air compressors, providing power support for various pneumatic equipment and automated production lines. During the air compression process, due to physical actions such as mechanical friction and gas compression, air compressors generate a large amount of waste heat, mainly concentrated in cylinder cooling, the lubricating oil circulation system, and the exhaust process. This waste heat contains considerable energy, and effective recovery and utilization will significantly improve energy efficiency, aligning with the current development trend of energy conservation, emission reduction, and green production.

[0003] However, traditional air compressor stations generally lack effective recovery and recycling mechanisms for the aforementioned waste heat. Most air compressor stations simply discharge the waste heat directly into the environment through simple air cooling or water cooling, which not only causes a large amount of energy waste, but may also lead to an increase in workshop ambient temperature and increase ventilation and cooling costs. This makes traditional air compressor stations poor in terms of energy utilization and difficult to meet the requirements of modern industry for energy conservation, consumption reduction and circular economy. Utility Model Content

[0004] The purpose of this application is to provide an energy-saving circulation device for an air compressor station. The waste heat recovery component can efficiently collect waste heat from the main body of the air compressor. Then, the filter component in the transmission pipeline can filter impurities in the medium. At the same time, it does not require frequent manual maintenance, ensuring stable system operation. Then, the main pump and the standby pump are automatically switched by the controller to ensure continuous medium delivery. Combined with the circulation pump and the return pipeline, a closed-loop circulation of the medium is formed, which further improves the waste heat recovery efficiency and solves the problems mentioned in the background technology.

[0005] This application provides an energy-saving circulation device for an air compressor station, which adopts the following technical solution: An energy-saving circulation device for an air compressor station includes an air compressor body. A waste heat recovery component is provided on one side of the air compressor body. The waste heat recovery component includes an insulated box. A heat conduction storage box is fixedly installed inside the insulated box. A support frame is provided on the other side of the waste heat recovery component. A transmission pipe is provided inside the support frame. One end of the transmission pipe extends through the outside of the insulated box to the inside of the heat conduction storage box. A filter component is provided inside the transmission pipe. The filter component includes a fixed frame fixedly connected to the inside of the transmission pipe. Four circumferentially arrayed filter screens are fixedly connected to the inside of the fixed frame. A dual-path diversion pipe is fixedly connected to one end of the transmission pipe. A main pump body and a standby pump body are fixedly installed on the two branch pipes of the dual-path diversion pipe, respectively. An application device is fixedly connected to the other end of the dual-path diversion pipe. A controller is fixedly installed on the outside of the insulated box.

[0006] By adopting the above technical solution, the waste heat generated by the main body of the air compressor can be collected and stored in the heat-conducting storage tank through the waste heat recovery component, and the heat-insulating tank reduces heat loss. Then, the transmission pipeline transports the heat energy medium to the dual-path diversion pipeline, and after being pressurized by the main pump or the standby pump, it is supplied to the application equipment, realizing the recovery and recycling of waste heat, avoiding the energy waste caused by the direct discharge of waste heat from traditional air compressor stations, thereby meeting the heat energy needs of surrounding production and life. At the same time, the filter screen in the filter component can filter impurities in the medium, avoid blockage of the transmission pipeline, ensure stable operation of the system, and the controller realizes centralized control of the equipment, improving the convenience of operation.

[0007] Preferably, the insulation box and the air compressor body are fixedly connected by a pipe, an exhaust pipe is fixedly connected to the inner side of the insulation box, and an electrically controlled valve is fixedly installed on the outer side of the exhaust pipe. The electrically controlled valve and the controller are electrically connected.

[0008] By adopting the above technical solution, the insulation box is connected to the air compressor body through a pipeline, allowing the high-temperature flue gas generated by the air compressor to enter the exhaust pipe. The controller can control the opening and closing of the electronically controlled valve and flexibly adjust the amount of flue gas discharged, thereby fully recovering the waste heat in the flue gas and improving the controllability of waste heat recovery.

[0010] By adopting the above technical solution, when the rotating shaft rotates, it drives the fixing frame and cleaning brush to rotate synchronously. The cleaning brush contacts the filter screen to remove the impurities attached to the filter screen, avoiding the filter screen from clogging and affecting the transmission of media. It eliminates the need for frequent manual disassembly and cleaning, reduces maintenance costs, and ensures the continuous and effective operation of the filter components.

[0011] Preferably, a conical block is fixedly connected to one end of the rotating shaft, and an impeller blade is fixedly connected to the outer side of the rotating shaft.

At the same time, the conical block can guide the medium to flow to the impeller blades, enhance the impact force of the medium on the blades, improve the rotation efficiency of the shaft, and ensure the cleaning effect of the cleaning brush.

[0015] Preferably, both the main pump body and the standby pump body are electrically connected to the controller.

[0016] By adopting the above technical solution, the controller can control the start and stop of the main pump and the standby pump. Under normal operating conditions, the main pump will transport the medium. When the main pump fails, the controller can automatically switch to the standby pump to ensure the continuity of heat energy medium transportation and avoid the interruption of waste heat utilization due to pump failure.

[0018] By adopting the above technical solution, the cryogenic medium after the application equipment is used can be transported back to the heat transfer storage tank through the circulation pump and return pipeline, forming a closed loop circulation of the medium, reducing medium consumption. At the same time, the return of the cryogenic medium can absorb new waste heat, improve the waste heat recovery efficiency, and realize the recycling of energy.

[0028] Example 2: An energy-saving circulation device for an air compressor station, please refer to... Figure 1 , Figure 2 and Figure 4The insulation box 201 and the air compressor body 1 are fixedly connected by pipes. An exhaust pipe 203 is fixedly connected to the inner side of the insulation box 201, and an electrically controlled valve 204 is fixedly installed on the outer side of the exhaust pipe 203. The electrically controlled valve 204 is electrically connected to the controller 15. The insulation box 201 and the air compressor body 1 are connected by pipes, allowing the high-temperature flue gas generated by the air compressor to enter the exhaust pipe 203. The controller 15 can control the opening and closing of the electrically controlled valve 204, flexibly adjusting the flue gas discharge volume, thereby fully recovering the waste heat in the flue gas and improving the controllability of waste heat recovery.

[0029] The implementation principle of this application embodiment is as follows: First, the waste heat generated by the air compressor body 1 enters the waste heat recovery component 2 through the connecting pipe. High-temperature flue gas enters the insulation box 201 through the exhaust pipe 203. The controller 15 can control the opening and closing of the electronically controlled valve 204 according to the waste heat recovery requirements, adjusting the flue gas discharge volume to ensure sufficient heat exchange between the flue gas and the heat transfer medium in the heat transfer storage box 202. Simultaneously, the insulation box 201 reduces heat loss within the heat transfer storage box 202, achieving efficient collection and storage of waste heat. Subsequently, the heat transfer medium in the heat transfer storage box 202 is transported through the transmission pipe 4. When the medium flows through the filter component 5, the four circumferentially arrayed filter screens 502 inside the fixed frame 501 filter impurities in the medium. Simultaneously, the medium impacts the impeller blades 507 during flow, causing the rotating shaft 503 to rotate. The conical block 506 at one end of the rotating shaft 503 guides the medium to flow better towards the impeller blades 507, lifting the rotating shaft 503. 03 Rotation efficiency: When the rotating shaft 503 rotates, it will also drive the fixed frame 504 and cleaning brush 505 to rotate synchronously. The cleaning brush 505 contacts the filter screen 502 and automatically removes the impurities attached to the filter screen, ensuring smooth transmission of the medium. Then, the filtered heat energy medium enters the dual-path diversion pipe 6 through the transmission pipe 4 connected by the flange and the dual-path diversion pipe 6. The composite heat insulation structure formed by the aluminum silicate fiber cotton layer 12, the steel protective shell 13 and the polyurethane foam layer 14 on the outside of the dual-path diversion pipe 6 can reduce the heat loss during the medium transportation process. Then, the controller 15 controls the main pump body 7 or the standby pump body 8 to operate, pressurize the medium and deliver it to the application equipment 9 for its use. Finally, the low temperature medium used by the application equipment 9 is transported back to the heat transfer storage tank 202 through the return pipe 11 under the action of the circulation pump 10, and absorbs the waste heat again to form a closed loop circulation of the medium, realizing the continuous recovery and recycling of waste heat.
