The permeability of the filter screen is reduced after clogging, thereby reducing the flow rate of the exhaust gas. Therefore, it is necessary to disassemble the treatment equipment to clean the filter mechanism. This cleaning method is cumbersome and laborious, and reduces the purification efficiency of the exhaust gas. Utility Model Content

The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a waste gas pollution control and absorption device. Figure 1-5 As shown, it includes a purification chamber 1, an air inlet pipe 2 is connected to the lower left side of the purification chamber 1, a filter plate 3 is installed on the inner wall of the purification chamber 1, a fixing frame 4 is installed on the inner wall of the purification chamber 1, a rotating shaft 5 is installed at the center of the fixing frame 4 through a bearing, a spiral blade 6 is installed at the lower end of the rotating shaft 5, a brush plate 7 is installed on the upper end of the rotating shaft 5, the brush plate 7 fits the lower surface of the filter plate 3, an ash box 8 is installed at the bottom of the purification chamber 1, a positioning frame 13 is installed on the side of the ash box 8, the positioning frame 13 is set to be L-shaped, a positioning slot is provided on the lower inner wall of the purification chamber 1 to match the horizontal plate of the positioning frame 13, an adsorption plate 16 is installed on the top inner wall of the purification chamber 1, and vertical ventilation slots 17 are evenly opened in the middle of the adsorption plate 16, an exhaust pipe 9 is installed on the top of the purification chamber 1, when the device is in use, the exhaust gas enters the interior of the purification chamber 1 from the air inlet pipe 2, and The exhaust gas flows upward from the bottom of the purification chamber 1, and is first filtered by the filter plate 3. The filter plate 3 filters out the particulate matter in the exhaust gas. The filtered exhaust gas then passes through the adsorption plate 16. The adsorption plate 16 is made of activated carbon. The activated carbon can adsorb and purify the harmful substances in the exhaust gas. The purified gas is then discharged from the exhaust pipe 9. The device is provided with a spiral blade 6 and a brush plate 7. When the exhaust gas flows upward from the bottom of the purification chamber 1, the spiral blade 6 rotates driven by the airflow, and the brush plate 7 rotates driven by the rotating shaft 5, thereby scraping the lower surface of the filter plate 3. Through this setting, the dust particles adhering to the surface of the filter plate 3 can be scraped off, thereby avoiding clogging of the filter holes of the filter plate 3 and ensuring long-term normal use of the filter plate 3. The scraped dust will fall into the ash box 8 at the bottom of the purification chamber 1 under the action of gravity, thereby realizing dust collection.

[0022] There are three groups of filter plates 3, which are installed at equal distances from bottom to top and the apertures of the filter holes decrease successively. There are three groups of brush plates 7, which are respectively attached to the lower surfaces of the three groups of filter plates 3. By providing three groups of filter plates 3, the three groups of filter plates 3 can filter particles of different sizes respectively, thereby improving the purification effect of exhaust gas.

[0023] A slot matching the width of the filter plate 3 is provided on the right side of the pipe wall of the purification chamber 1. The right end of the filter plate 3 extends to the outside of the purification chamber 1. The three groups of filter plates 3 are connected by a connecting frame 10. A handle 12 is installed on the outer surface of the connecting frame 10. By providing the connecting frame 10, the three groups of filter plates 3 are connected by the connecting frame 10. The connecting frame 10 can be pulled to pull the three groups of filter plates 3 out from the right side of the purification chamber 1 at the same time. This arrangement can make the disassembly and assembly of the filter plates 3 more convenient and labor-saving.

[0024] The distance between the spiral blade 6 and the inner wall of the purification chamber 1 is reduced relative to the upper and lower ends. The flow rate of the airflow at the position of the spiral blade 6 is increased by reducing the diameter, thereby avoiding the low exhaust gas flow rate that cannot drive the spiral blade 6 to rotate.

[0025] A strip-shaped notch that matches the diameter of the rotating shaft 5 is opened on the left side of the filter plate 3. A sealing plate 11 is installed on the inner wall of the purification chamber 1 at the position where the filter plate 3 is located. The sealing plate 11 is located at the notch of the filter plate 3. The notch is opened on the left side of the filter plate 3 to meet its horizontal pulling requirements. The sealing plate 11 can cover the notch when the filter plate 3 is placed, so as to prevent the exhaust gas from flowing out of the notch of the filter plate 3 and causing incomplete filtration.

[0026] A fixed frame 14 is installed between the purification chamber 1 and the ash box 8. A wind blocking plate 15 is slidably installed on the inner wall of the fixed frame 14. The wind blocking plate 15 can be pulled out horizontally. By providing the wind blocking plate 15, when the ash box 8 needs to be pulled out, the wind blocking plate 15 can be inserted back into the inner side of the fixed frame 14 first. At this time, the bottom of the purification chamber 1 is sealed, and then the ash box 8 can be pulled out for cleaning. This setting can prevent exhaust gas from flowing out from the bottom of the purification chamber 1 when the ash box 8 is pulled out.
