Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an improved waste gas treatment and collection device. Background Technique

[0002] Waste gas treatment refers to the process of purifying and rendering harmless the waste gas generated during industrial production, transportation, domestic heating, etc. through physical, chemical or biological methods. Its purpose is to reduce the pollution of harmful substances in the waste gas to the atmospheric environment, reduce the impact on human health, and comply with China's environmental protection regulations and international environmental protection standards. Waste gas treatment technologies include adsorption, desulfurization, denitrification, dust removal, photocatalytic oxidation, biological filter, etc. Appropriate treatment technologies are selected according to the composition and concentration of the waste gas to achieve the reduction, harmlessness and resource utilization of the waste gas.

[0003] The patent document with the application number CN202121659883.9 discloses an industrial acidic waste gas treatment and collection device. Among them, it includes a device body. One end of the lower part of the device body is provided with a connecting device. One end of the lead screw is rotatably connected to the connecting plate through a pin shaft. The inner side of the connecting plate is fixedly connected to the outer wall of the air inlet. One end of the air inlet is communicated with the device body. In this industrial acidic waste gas treatment and collection device, through the cooperation between the device body and the connecting device, the sealing ring on the annular plate is contacted. At this time, by dragging the rings on both sides, the lead screws are respectively driven to rotate through the pin shafts in the connecting plates on both sides and are stuck in the grooves on the cuboids on both sides. Rotate the nut and press it against the cuboid to quickly connect the external interface to the air inlet, which is convenient for connection and installation, and solves the problem that in the existing industrial acidic waste gas treatment and collection device during use, since the exhaust pipe is connected to the device air inlet pipe by a flange and is not conducive to connection and installation. Based on the retrieval of the above patent and the combination with the waste gas treatment and collection devices in the existing technology, it is found that during the application of the waste gas treatment and collection device, dust and particulate matter are likely to accumulate inside the pipeline. For a long time, when the gas passes through the gas transmission pipeline, the tiny dust and particulate matter in it often settle on the inner wall of the pipeline, especially on the elbow and straight pipe, resulting in ash accumulation on the inner wall of the pipeline. This not only reduces the effective flow area of the pipeline, affects the gas transmission efficiency, but also increases the burden on the pipeline and may cause safety risks to the pipeline structure.
