Abstract

The utility model is a harmful gas treatment device for chemical production, and its structural components mainly include a tower body, a filter chamber, a transition box, a reaction chamber, a reaction filler and a spray system. There is a dust collecting funnel at the bottom, which is used to collect the swept dust into the dust collecting box. The exhaust gas is pumped into the filter chamber through the air intake pump, filtered through the concave dust filter cylinder, enters the vent cylinder and is discharged through the upper mesh. The water pump pumps the external catalytic liquid into the transition box through a pipeline, and enters the spray rod through the hollow shaft at the upper end of the transition box. The spray rod sprays the catalytic liquid to react with the reaction filler to catalytically decompose the exhaust gas, which is discharged from the exhaust port. At the same time, when the gas enters the vent cylinder, it blows the spiral fan blades, driving the hollow shaft to rotate. The central control shaft drives the concave dust filter cylinder and the spray rod to rotate. The spray rod rotates to spray, expanding the spraying range and ensuring that the catalytic liquid is in uniform contact with the floating gas. At the same time, the concave dust filter cylinder will contact the cleaning brush during the rotation process to clean the dust accumulated on the surface.
