Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment adsorption device. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. In recent years, with the continuous advancement of urbanization and the continuous improvement of industrial production levels, the emission of waste gas has aggravated environmental pollution. In order to further strengthen environmental protection and improve the quality and level of life, the state and governments at all levels have successively introduced various policies to encourage and support the development of the waste gas treatment industry. The activated carbon adsorption box for waste gas treatment has the advantages of low manufacturing cost, small footprint and strong adsorption capacity. It is widely used in the waste gas treatment industry. When the existing waste gas treatment activated carbon adsorption box is working, the waste gas in the workshop is driven by a negative pressure fan and transported through a pipeline into the activated carbon box. When the organic gas enters the box, the exhaust port The negative pressure fan works, and the internal pressure difference causes the exhaust gas to flow into the activated carbon filter layer in the activated carbon box. When the exhaust gas enters the carbon layer, the harmful gas contained inside is adsorbed by the activated carbon, and the clean air passes through the carbon layer and is discharged. During the adsorption process, the carbon will have a saturation period. The length of the activated carbon saturation process is related to the concentration of the gas contained in the gas itself and the length of time it works. After working for a long time, the saturated activated carbon box needs to be replaced. When installing the activated carbon box in the traditional exhaust gas treatment activated carbon adsorption box, a large number of bolts are required for fixing and sealing. The activated carbon box has a long replacement cycle and a heavy labor burden, which is quite inconvenient. For this reason, we propose an exhaust gas treatment adsorption device.

[0026] The working principle of an exhaust gas treatment adsorption device provided by the utility model is as follows: when the exhaust gas is treated by the exhaust gas treatment activated carbon adsorption box, the exhaust gas is driven by the negative pressure fan at the air inlet end and enters the shell 1 through the pipe. At this time, the negative pressure fan at the air outlet end works, and a pressure difference is formed inside the shell 1. The exhaust gas passes through the activated carbon box 42. The outer surface of the activated carbon box 42 is provided with evenly distributed air holes. The activated carbon filter layer in the activated carbon box 42 adsorbs the harmful gases contained in the exhaust gas, and the clean gas is discharged through the negative pressure fan at the air outlet end. After working for a long time, the activated carbon filter layer inside the activated carbon box 42 reaches a saturated state, and the activated carbon box 42 needs to be replaced. Hold the handle 464 and pull it to the right. The spring 2 463 is compressed by force so that the limit protrusion 462 is fully Leaving the limiting groove, the mounting block 461 loses its restriction, deflecting the handle 464 backward by ninety degrees, driving the mounting block 461 and the connecting shaft 451 to deflect backward by ninety degrees, and the cam 452 deflects backward by ninety degrees synchronously. At this time, the inner end of the locking rod 453 is not subjected to force, and the spring 454 rebounds without force, driving the locking rod 453 to move inward synchronously until the outer end of the locking rod 453 completely leaves the locking mouth. At this time, the frame 41 loses its restriction, and the guide wheel 43 contacts the inner wall of the shell 1, which can ensure that the frame 41 is easily pulled out. As the frame 41 is pulled out to the right, the right side of the limiting plate 446 contacts the right side wall of the limiting groove 9. At this time, the rack plate 441 does not move, and as the frame 41 continues to move right, the gear 442 also moves to the right, because the gear The wheels 442 are meshed with the vertically adjacent rack plates 441, so the left rotation of the gear 442 drives the fixing plate 443 to deflect to the left, and the tension spring 445 is expanded under the force until the frame 41 moves to the appropriate position. At this time, the fixing plate 443 leaves the surface of the activated carbon box 42, and the activated carbon box 42 loses its restriction. Then the new activated carbon box 42 is replaced, and the frame 41 is closed to the left. As the frame 41 moves to the left, the limiting plate 446 leaves the right side wall of the limiting groove 9, and the tension spring 445 slowly contracts without force, driving the rack plate 441 back to its original position, and the gear 442 also rotates to the right synchronously, and the fixing plate 443 also deflects to the left synchronously, forming a fixing effect on the activated carbon box 42, until the right side wall of the frame 41 contacts the left side wall of the installation groove, and the handle 464 is held tightly to move to the left. The locking bar 453 is then deflected forward by 90 degrees, and the limiting protrusion 462 is also deflected forward by 90 degrees, pressing the inner end of the locking rod 453, causing the locking rod 453 to move outward synchronously. At this time, the inclined surface 1 at the outer end of the locking rod 453 contacts the inclined surface 2 inside the locking port, so that the right side wall of the frame 41 contacts the left side wall of the mounting groove more closely, and then the handle 464 is released, and the spring 2 463 expands without force, driving the mounting block 461 to move left, and the limiting protrusion 462 also moves left synchronously into the limiting groove to form a limit. At this time, the anti-loosening work is completed, and the handle 464 is deflected to the right, so that the handle 464 fits the surface of the frame 41, and the handle 464 is stored. An activated carbon box replacement mechanism is provided, which can quickly replace the activated carbon box for exhaust gas treatment adsorption, reducing the manual burden.It greatly shortens the replacement cycle of activated carbon cartridges for waste gas treatment and adsorption, which is convenient and quick.
