Heating device for drying painted parts

Abstract

The invention discloses a heating device for drying painted parts. The heating device comprises a painting room; an air blower for supplying hot air to the painting room and an electric heater are arranged outside the painting room; the air blower and the electric heater communicate with the top of the painting room through an intake pipe; the electric heater is positioned in the intake pipe; an air outlet of the air blower is tightly connected with the intake pipe; an exhaust pipe, communicating with the painting room, is arranged at the bottom of the painting room; an air outlet of the exhaust pipe is connected with a plasma waste gas purifier; and an air outlet of the plasma waste gas purifier is connected with an air inlet of the air blower through a circulating pipe. The exhaust pipeis arranged at the bottom of the painting room, and is connected with the plasma waste gas purifier; and the plasma waste gas purifier can decompose paint mist waste gas in the painting room within shorter time, and generates various subsequent reactions to achieve the purpose of pollutant degradation, so that the qualified emission of the waste gas in the painting room is realized, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to a heating device for drying painted parts. Background technique [0002] At present, in industrial production, in order to meet the requirements of the painting process, some painted parts need to be reprocessed at an appropriate temperature. The heating equipment on the market uses combustion furnaces to provide heat sources. At the same time, most combustion furnaces use fuel oil for high-temperature heating. The fuel used in the painting combustion chamber is mostly diesel oil, which produces soot during the combustion process, which will have an adverse effect on the quality of the painted workpiece. At the same time, the equipment produces a large amount of pollutants during operation, which pollutes the operating environment and greatly affect the health of workers. Contents of the invention [0003] What the present invention aims to solve is that the existi...
