[0002] Waste gas treatment mainly refers to the work of injecting dust particles, flue gas, odorous gases, toxic and harmful gases into industrial waste gas generated in industrial sites for treatment. Common waste gas treatments include factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc.

[0003] The Chinese patent with patent number CN214715443U discloses a high-efficiency cyclone dust removal and demisting device, including a demisting unit, a dust removal unit and a wastewater recovery unit. The dust removal unit includes a cylinder, an exhaust port is provided on the upper part of the cylinder, and the exhaust port is connected to the demisting unit.

[0004] During use, the above-mentioned patent can enhance the cyclonic properties of exhaust gas and improve dust removal efficiency by setting multiple cyclone plates, and recycle wastewater using filter layers and purification boxes to achieve recycling of water resources. However, after the filter layer filters a large amount of dust particles, the dense dust particles completely block the filter layer, causing the wastewater mixed with the exhaust gas to be unable to be filtered and flow into the filter liquid holding space. Replacing the new filter layer requires suspending the operation of the dust removal and demisting device, resulting in a decrease in the working efficiency of the dust removal and demisting device. Therefore, a new type of high-efficiency cyclone dust removal and demisting device specially designed for the slag pit of an incineration power plant is urgently needed to solve these problems.
