Problems solved by technology

However, there are the following problems in the current treatment method of spraying water: First, although UV light-curable varnish is an environmentally friendly coating, it will form colloidal block substances and flocculent suspended matter when mixed with water before curing, and solid waste treatment is difficult. Second, the efficiency of spraying water to treat paint mist is low, and paint mist must be flocculated by water treatment agents in water, which pollutes water greatly
Moreover, under the control of environmental protection, paint mist that is not soluble in water can only be absorbed by filter bags. The adsorption effect is poor, the adsorption cost is high, and solid waste treatment is difficult. Because UV light-curable varnish is a flame-retardant resin, solid waste treatment is likely to be incomplete.

Abstract

The invention relates to the technical field of environmental protection and discloses UV light-cured varnish spraying waste gas recycling equipment and a technology. The equipment comprises a collection tower, a deflecting deceleration air-duct and a drying curing box which are successively communicated. Multiple layers of separating plates are fixedly installed inside the collection tower. An ultraviolet lamp tube is installed at the upper part inside the drying curing box. By the utilization of characteristics of varnish waste gas, the varnish waste gas successively undergoes gas-to-liquidconversion recovery, ultraviolet radiation curing, dust recovery, UV photolysis or activated carbon adsorption box adsorption, and finally the varnish spraying waste gas is discharged. The waste gas treatment is safe and environmentally friendly, and varnish waste gas is recycled and reused so as to save cost. Recycling of varnish waste gas is realized, and the equipment is safe, reliable and environmentally friendly by the curing process of the waste gas which is not completely recovered. The equipment is safe and environmentally friendly, and the technology is simple and effective.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a waste gas recycling and processing equipment for UV photocuring varnish spraying. Background technique [0002] UV light-curing varnishes have been used in the spraying and finishing of plastic parts of two-wheeled electric vehicles and motorcycles for more than 20 years, but the waste gas produced by spraying, such as a misty UV paint and ethyl acetate mixture, has been sprayed with water. deal with. However, there are the following problems in the current treatment method of spraying water: First, although UV light-curable varnish is an environmentally friendly coating, it will form colloidal lumps and flocculent suspended matter when mixed with water before curing, and solid waste treatment is difficult. Second, the efficiency of spraying water to treat paint mist is low, and paint mist must be flocculated by water treatment agents in water, which pollutes ...
