Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas after-treatment devices, specifically relating to a waste gas filtration channel with a pressure relief side support structure. Background Technology

[0002] An exhaust gas filtration system is a device or system specifically designed to remove various pollutants, such as particulate matter, gaseous pollutants, and odors, from exhaust gases. In industrial production and environmental protection, this device plays a crucial role and is an indispensable key element. Its main core objectives encompass multiple aspects, including effectively purifying gases to meet emission standards, recovering and reusing valuable resources from the exhaust gases, and eliminating odors, thereby reducing the impact on the environment and human health.

[0003] Most widely used exhaust gas filtration devices employ a method of filtering exhaust gas using specific filter materials. After operating for a period of time, as the filtration process continues, the filter material may gradually become clogged by impurities in the exhaust gas. Once the filter material becomes clogged, it can lead to a series of problems, such as backflow caused by the inability of exhaust gas to be discharged normally, or localized increases in air pressure inside the pipeline. These problems will affect the normal operation and filtration efficiency of the exhaust gas filtration device.

[0004] To effectively prevent adverse phenomena such as exhaust gas backflow or localized pressure increases in the pipeline caused by filter material blockage, this invention proposes an innovative solution: an exhaust gas filtration channel with a pressure relief side support structure. This special structural design can promptly regulate the air pressure in the pipeline through the pressure relief side support structure when the filter material shows signs of blockage, preventing exhaust gas backflow and ensuring the continuous and stable operation of the exhaust gas filtration device, thereby improving its working efficiency and service life. Utility Model Content

[0005] The purpose of this invention is to provide an exhaust gas filtration channel with a pressure relief side support structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waste gas filtration channel with a pressure relief side support structure includes a main channel, a detachable filter screen assembly located in the middle of the main channel, the filter screen dividing the main channel into an upper section and a lower section, a pressure relief side support connecting the upper and lower sections of the main channel, and a valve plate assembly inside the pressure relief side support.

[0008] Preferably, the main channel is provided with connecting flanges at both the upper and lower ends.

[0009] Preferably, the filter assembly includes a filter base, the upper top surface and the lower bottom surface of the filter base being connected to the upper section and the lower section of the main channel, respectively; a slot is provided on the side wall of the filter base, and the filter assembly is disposed in the slot.

[0010] Preferably, the filter assembly includes a filter plate frame, and a filter screen is provided on the inner side of the filter plate frame.

[0011] Preferably, locking bolts are provided at the filter base and the filter plate frame, and the locking bolts lock the filter plate frame.

[0012] Preferably, the valve plate assembly includes a valve plate seat and a valve plate; the valve plate seat is fixed to the inner wall of the pressure relief side support, the valve plate is hinged to the valve plate seat, the valve plate is located on the upper top surface of the valve plate seat, and the valve plate covers the valve plate seat from above.

[0013] Preferably, a magnetic attraction element is provided between the valve plate and the valve plate seat.

[0014] Preferably, a weight block is provided on the top of the valve plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The exhaust gas filtration channel with pressure relief side support structure provided by this utility model adopts pressure relief side support. When the local gas pressure in the lower section of the main channel is too high, the gas pushes open the valve plate assembly and the gas enters the upper section of the main channel through the pressure relief side support.

[0017] (2) The present invention provides an exhaust gas filtration channel with a pressure relief side support structure. The valve plate assembly includes a valve plate seat and a valve plate. The valve plate assembly is hinged to the valve plate seat, and the valve plate covers the valve plate seat from the top. Since the valve plate has its own weight, airflow is required to overcome the weight of the valve plate to open the valve plate. The weight of the valve plate can be adjusted. The greater the weight of the valve plate, the greater the air pressure required to open the valve plate.

[0018] (3) The exhaust gas filtration channel with pressure relief side support structure provided by this utility model has a magnetic suction component between the valve plate and the valve plate seat. The magnetic suction component can increase the gas pressure required to open the valve plate. The suction force of the magnetic suction component can be adjusted as needed.
