Description

Technical Field

[0001] The present invention relates to the technical field related to waste gas treatment equipment, and in particular to a waste gas treatment equipment with a multi-layer filtering structure. Background Art

[0002] Waste gas treatment equipment refers to equipment used to treat harmful gases, which is designed to protect the environment and ensure that our environment is not polluted. The working principles and application technologies of waste gas treatment equipment are diverse, including the removal and cleaning of solid particles in the waste gas, thereby reducing the pollution caused by the gas discharged to the outside, which is in line with the concept of environmental protection and sustainable development; For example, announcement number CN116531885A discloses an exhaust gas filtering and processing device, including an air collecting hood, a primary processing mechanism, a secondary processing mechanism, a tertiary processing mechanism and a fan. During the exhaust gas processing, the fan works, and the exhaust gas enters the primary processing mechanism through the air collecting hood, and the primary processing mechanism filters and removes dust from the exhaust gas. Then, the exhaust gas after dust removal flows into the secondary processing mechanism, which is used to perform water-soluble treatment on the exhaust gas, so as to perform water-soluble treatment on the dust that has not been completely filtered in the exhaust gas again, and at the same time, it can process the water-soluble gas in the exhaust gas; then, the exhaust gas flows into the tertiary processing mechanism, which is used to adsorb the exhaust gas; finally, the treated gas is discharged to the outside. In this process, the exhaust gas is subjected to multi-stage treatment through multi-stage mechanisms, which can improve the treatment effect of the exhaust gas; As disclosed in announcement number CN220558792U, an exhaust gas treatment device that is easy to disassemble the filter screen includes a treatment chamber, an air intake chamber and a filter screen body. The air intake chamber is fixedly installed at the upper end of the treatment chamber. The treatment chamber is provided with a cleaning mechanism that is easy to clean and disassemble the filter screen body. The cleaning mechanism includes a cleaning box and a pressure plate. The cleaning box is fixedly installed at the side end of the treatment chamber. Both the upper and lower ends of the cleaning box are penetrated with movable grooves. There are two pressure plates. Cleaning brushes are fixedly installed on the side ends of the opposite surfaces of the two pressure plates. The utility model can collect impurities after scraping by setting a dust exhaust pipe and a dust collecting box. The cleaning and collection steps are all completed in the cleaning box, the dust exhaust pipe and the dust collecting box to avoid dust. It ensures environmental protection while treating the filter screen body and has high practicality. However, the existing waste gas treatment equipment still has the following shortcomings: 1. Most of the existing waste gas treatment equipment only uses a single filter to filter the waste gas. However, the solid particles in the waste gas often have different diameters, which makes it inconvenient to perform multi-stage filtration on the solid particles in the waste gas, and it is also inconvenient to scrape off the solid particles adhering to the filter. 2. When cleaning the solid particulate impurities filtered out, the existing waste gas treatment equipment needs to stop the equipment to ensure that the unfiltered waste gas will not be discharged. After cleaning the impurities, the equipment needs to be restarted for filtering, which is time-consuming and affects the efficiency of waste gas treatment. It is inconvenient to directly clean the impurities when the equipment is running; 3. The existing waste gas treatment equipment has limited effect of filtering only through the filter net, and fine dust particles will still pass through the filter net, which is inconvenient to further adsorb the filtered waste gas before it is discharged; For example, the comparative patents listed above have this problem; Therefore, we provide an exhaust gas treatment device with a multi-layer filtering structure to solve the above-mentioned problems. Summary of the invention

In many cases, the diameters of the solid particles contained in the exhaust gas are different, which makes it inconvenient to perform multi-stage filtering on the solid particles in the exhaust gas, and it is also inconvenient to scrape off the solid particles adhering to the filter mesh. When cleaning the filtered solid particle impurities, it is necessary to stop the equipment from running to ensure that the unfiltered exhaust gas will not be discharged. After cleaning the impurities, the equipment needs to be restarted for filtering, which is time-consuming and affects the efficiency of exhaust gas treatment. It is inconvenient to directly clean the impurities when the equipment is in operation. The effect of filtering only through the filter mesh is limited, and fine dust particles will still pass through the filter mesh, making it inconvenient to perform further adsorption treatment on the filtered exhaust gas before it is discharged.
