Technical Field

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

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. In particular, chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries emit strong odors of waste gas, which seriously pollutes the environment and affects human health. In order to prevent environmental pollution, some devices are needed to treat the waste gas.

[0003] After searching, it was found that an exhaust gas collection and treatment device disclosed in announcement number CN220609571U has a technical solution including a collection box, the top of which is fixedly connected with an air intake pipe, which passes through the collection box. Although the above device is convenient for cleaning or replacing the first filter screen and the second filter screen when in use, it is difficult for the device to continue to treat the exhaust gas when the filter screen is cleaned, thereby reducing the efficiency of the device in treating the exhaust gas. Therefore, an efficient exhaust gas collection and treatment device is proposed. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when the filter screen is cleaned, the device is difficult to continue to treat the waste gas, which reduces the efficiency of the device in treating the waste gas, and proposes a waste gas efficient collection and treatment device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An air inlet pipe is fixedly connected to the top of the treatment cylinder, and an exhaust pipe is installed on the circumference of the treatment cylinder.

[0008] As a further solution of the utility model, an activated carbon adsorption plate and a catalyst adsorption plate are installed in the processing cylinder, and the activated carbon adsorption plate and the catalyst adsorption plate are located below the filter screen.

[0009] As a further solution of the utility model, a discharge rod is rotatably connected between the two ends of the slag discharge barrel, and a spiral blade for feeding is fixedly connected to the circumference of the discharge rod.

[0010] As a further solution of the utility model, the circumferential inner wall of the processing cylinder is fixedly connected to a fixing frame, the top of the fixing frame is rotatably connected to a penetrating rotating shaft, the top of the rotating shaft is fixedly connected to a plurality of fan blades, the circumference of the rotating shaft is fixedly connected to at least one supporting rod, and the bottom of the supporting rod is fixedly connected to a brush plate for cleaning the filter.

[0013] In the present application, when in use, the exhaust gas enters the treatment cylinder through the air inlet pipe and is then discharged through the exhaust pipe.

The rotating shaft drives the brush plate to rotate through the support rod. The brush plate cleans the filter, and the cleaned impurities enter the slag discharge cylinder. When cleaning the impurities, the discharge rod is rotated, and the discharge rod drives the spiral blade to rotate. The spiral blade pushes the impurities in the slag discharge cylinder downward and then enters the slag collecting cylinder. The plug is then pulled by the pull rod to push the impurities into the discharge port and then fall. At the same time, the plug closes the feed port of the slag collecting cylinder to prevent air from being discharged, thereby improving the working efficiency of the device and avoiding shutdown operations. The air filtered by the filter is also filtered by the activated carbon adsorption plate and the catalyst adsorption plate to improve the air filtering effect.

[0017] In the utility model, impurities in the exhaust gas can be collected through the slag discharge tube, and the impurities can fall into the slag collecting tube, and then be collected, which is convenient for processing and improves the working efficiency of the device. At the same time, the fan blades can be blown by the exhaust gas to drive the rotating shaft to rotate, and the rotating shaft can drive the brush plate to rotate through the support rod, and the brush plate can clean the filter, which is convenient for the filter to work for a long time.
