Technical Field

[0001] The utility model relates to the field of air compressor waste heat recovery, in particular to an air compressor waste heat recovery device with a water treatment and filtering function. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a buffer tank. The gas expands and flows in the impeller, thereby increasing the flow rate and pressure of the gas after passing through the impeller, and continuously producing compressed air. In this process, a large amount of heat is generated, which is generally cooled by cooling water in a cooling tower and discharged into the atmosphere through the cooling tower, causing thermal pollution. At present, the heat generated is recovered and reused through a waste heat recovery device.

[0006] By adopting the above technical solution, when water flows into the resin bed, the anion exchange resin and the cation exchange resin in the resin bed absorb ions and impurities in the water so as to purify the water.

[0007] Furthermore, a heat exchange pipe is installed inside the waste heat recovery tank, and a second liquid discharge pipe is connected to the bottom of the waste heat recovery tank.

[0008] By adopting the above technical solution, the waste heat generated by the air compressor can enter the interior of the heat exchange tube and heat the water in the waste heat recovery tank, thereby achieving the purpose of waste heat recovery.

[0009] Furthermore, a buffer tank is installed on one side of the filter tank, a water inlet end of the buffer tank is connected to a water pipe, and a water outlet end of the buffer tank is connected to a liquid outlet pipe extending to the inside of the filter tank.

[0010] By adopting the above technical solution, when water needs to be pumped into the interior of the filter tank, the external water pump can be started, and the water pump can pump water, and the water flows into the interior of the filter tank through the liquid outlet pipe.

[0011] Furthermore, a liquid inlet pipe and a backwash drain pipe are respectively installed on the water delivery pipe, and a solenoid valve is installed on both the liquid inlet pipe and the backwash drain pipe.

[0012] By adopting the above technical solution, water can enter the buffer tank through the liquid inlet pipe, and when the solenoid valve is closed, water cannot enter the water supply pipe through the liquid inlet pipe and the backwash drain pipe.

[0024] By adopting the above technical solution, when the movable plate moves, it will drive the limiting block to slide inside the limiting groove, thereby improving the stability of the movable plate when moving.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model is provided with a resin bed layer and a quartz sand layer. When water flows into the resin bed layer, the anion exchange resin and the cation exchange resin in the resin bed layer adsorb ions and impurities in the water to purify the water and prevent the water from generating scale when entering the waste heat recovery tank and being heated, thereby improving the recovery efficiency of waste heat;

[0027] 2. The utility model is provided with a blocking component. When water is pumped into the waste heat recovery tank by the liquid pump, it waits for a period of time to allow the hot air entering the heat exchange tube to heat the water, and then starts the drive motor. The drive motor can drive the screw to rotate, and then drive the movable plate to move. The movable plate drives the blocking column to move, so that the blocking column is moved out of the liquid guide hole. Since the density of cold water is greater than that of hot water between 4 degrees Celsius and 100 degrees Celsius, the hot water will be located above the cold water. As the liquid pump continues to pump room temperature water into the waste heat recovery tank, the heated hot water continues to flow upward and flows into the liquid storage tank through the liquid guide hole. In this way, water can be continuously pumped into the waste heat recovery tank, and the heated water can flow into the liquid storage tank through the liquid guide hole, while the unheated water is still accumulated in the lower part of the waste heat recovery tank, which is convenient for heating, thereby improving the heating efficiency of the water and avoiding that some water is discharged before being fully heated.

At this time, the waste heat generated by the air compressor will enter the heat exchange tube 20. Wait for a period of time to allow the hot air entering the heat exchange tube 20 to heat the water, and then start the drive motor 901. , the driving motor 901 can drive the screw rod 902 to rotate, and then drive the movable plate 905 to move, and the movable plate 905 drives the blocking column 906 to move, so that the blocking column 906 is moved out of the liquid guide hole 907. Since the density of cold water is greater than that of hot water between 4 degrees Celsius and 100 degrees Celsius, the hot water will be located above the cold water. As the pumping pump 908 continues to pump room temperature water into the waste heat recovery tank 1, the heated hot water continues to flow upward and flows into the liquid storage tank 19 through the liquid guide hole 907. In this way, water can be continuously pumped into the waste heat recovery tank 1, and the heated water can flow into the liquid storage tank 19 through the liquid guide hole 907, while the unheated water is still accumulated in the lower part of the waste heat recovery tank 1 to facilitate heating;
