Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an energy-saving and environmentally friendly air compressor exhaust gas treatment device. Background Technology

[0002] In the process of air compression, air compressors are usually used to compress air. However, the existing energy-saving and environmentally friendly air compressors have the following problem: during the operation of the air compressor, a certain amount of exhaust gas is generated. The exhaust gas will affect the environment where the air compressor is located. Users working in such an environment will have their health damaged by the exhaust gas.

[0003] The existing application publication number CN215196108U discloses an energy-saving and environmentally friendly air compressor exhaust gas treatment device, including a base plate, an air compressor body is arranged on the top left side of the base plate, a box is fixedly connected to the top right side of the base plate, a partition is fixedly connected inside the box, an exhaust pipe is connected to the top right side of the air compressor body, the side of the exhaust pipe away from the air compressor body extends into the interior of the box, a placement groove is opened on the top right side of the box, a cover plate is hinged to the left side of the inner wall of the placement groove by a pin, a through groove is opened on the top of the partition, and a purification mechanism is arranged on the right side of the inner cavity of the box, the purification mechanism includes a storage groove, a horizontal plate, a drawer and activated carbon balls.

[0004] However, this solution still has shortcomings. In actual use, due to the limited contact between the gas pipe and the liquid, the exhaust gas emission is too concentrated, and the contact area between the gas and the cleaning liquid is insufficient, resulting in incomplete reaction. At the same time, the lack of a filter screen in the device causes difficulties in subsequent cleaning and problems with the pores of the activated carbon being blocked.

[0005] Therefore, it is necessary to provide an energy-saving and environmentally friendly air compressor exhaust gas treatment device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving and environmentally friendly air compressor exhaust gas treatment device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an energy-saving and environmentally friendly air compressor exhaust gas treatment device, comprising an air compressor body, a cleaning box provided on the side of the air compressor body, a first cleaning chamber and a second cleaning chamber inside the cleaning box, the first cleaning chamber and the second cleaning chamber being separated by a partition, the top of the partition having an opening, an air inlet pipe being connected through the top of the first cleaning chamber, the upper end of the air inlet pipe being connected to the exhaust pipe of the air compressor body, a cleaning liquid being provided inside the first cleaning chamber, and the lower end of the air inlet pipe extending into the cleaning liquid and connected to a gas distribution coil. The first cleaning chamber is connected to a liquid inlet pipe and a liquid outlet pipe on its upper and lower sides, respectively. A first filter screen is provided on the side of the first cleaning chamber near the liquid outlet pipe. The interior of the second cleaning chamber is provided with a first water absorption zone, a second water absorption zone, and an activated carbon adsorption zone from top to bottom. An air outlet pipe is connected to the bottom right side of the second cleaning chamber. The gas distribution coil includes an inner ring pipe and an outer ring pipe. The outer ring pipe is located outside the inner ring pipe, and the air inlet pipe is connected to the inner ring pipe through the inner ring pipe connecting pipe. The air inlet pipe is connected to the outer ring pipe through the outer ring pipe connecting pipe. Multiple air outlet pipes are provided at the bottom of both the inner and outer ring pipes.

[0008] Preferably, the first absorbent area includes a first tray, and a first cotton board is provided above the first tray; the second absorbent area includes a second tray, and a second cotton board is provided above the second tray; both the first tray and the second tray are provided with vent holes.

[0009] Preferably, the activated carbon adsorption zone includes multiple activated carbon balls, and the second cleaning chamber is provided with a second filter screen on the side near the air outlet pipe.

[0010] Preferably, a screen is provided at the bottom of the first cleaning chamber.

[0011] Preferably, the inner ring pipe and the outer ring pipe are both on the same plane, and the gas outlet pipes on the inner ring pipe and the outer ring pipe are both annular and evenly distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the air inlet pipe is connected to an inner ring pipe and an outer ring pipe respectively, which disperses the gas and facilitates the discharge of waste gas. At the same time, the contact area between the gas and the cleaning liquid is greatly increased, thereby improving the cleaning efficiency. The inner ring pipe and the outer ring pipe are symmetrically arranged to ensure that the pressure and flow rate of the gas from each outlet pipe are highly consistent, avoiding excessive or insufficient local flow and improving the overall energy efficiency.

[0014] When the cleaning solution is discharged, the first filter screen can filter out impurities inside the cleaning solution, making subsequent cleaning easier. Simply lift the screen to improve cleaning efficiency. The double-layer cotton plate structure ensures that the gas is sufficiently dry, thus preventing the activated carbon balls from coming into contact with moisture and affecting their adsorption effect. The second filter screen can prevent the activated carbon balls from being carried out by the gas. Attached Figure Description
