Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a multi-porous burner RTO tail gas purification equipment. Background Art

[0002] As we all know, RTO exhaust gas purification equipment is a highly efficient exhaust gas treatment device that converts harmful substances in organic waste gas into harmless substances through thermal oxidation technology. The porous burner is usually located inside the combustion chamber of the RTO equipment. Its main function is to mix the exhaust gas to be treated with air and burn it under high temperature conditions. There are many tiny holes inside the porous burner, through which the exhaust gas and air can be evenly mixed together.

[0003] However, traditional porous burner RTO exhaust gas purification equipment is usually mainly used for exhaust gas mixing and combustion, without considering the filtration of exhaust gas before and after combustion, which affects the combustion efficiency and purification effect. Therefore, technical improvement is urgently needed. Utility Model Content

When the porous burner RTO exhaust gas purification device is in use, the exhaust gas to be purified is conveniently introduced through the exhaust gas inlet. At this time, the servo motor is started to drive the rotating rod to rotate while driving multiple ceramic filter plates to rotate. By driving the ceramic filter plates to rotate, the contact area between the exhaust gas and the filter plates can be increased, thereby effectively improving the contact and adsorption efficiency between the particulate matter in the exhaust gas and the filter plates, and avoiding excessive accumulation in some areas, resulting in excessive pressure loss or uneven effect. Through the multiple molecular sieve plates with different pore sizes in the discharge box, after the exhaust gas is burned, the particulate matter and organic compounds of different sizes in the gas to be discharged can be captured again, which can reduce the emission of pollutants.
