Description
Technical Field
The utility model relates to a waste gas treatment equipment field, especially a waste gas treatment device that paint spraying workshop used.
Background
In a factory production painting or plastic spraying work flow, paint coating operation is often required in an open workshop, such as an open workshop, a vehicle maintenance factory for vehicle maintenance painting, production vehicle painting, and the like. In actual production, to the waste gas that the spraying operation produced in open workshop, generally adopt exhaust-gas treatment equipment to handle, however, exhaust-gas treatment equipment installs at a fixed position, because its motor work drives the inspiratory waste gas scope of flabellum, consequently can only handle the waste gas in less regional space, like this when workman carries out multiple spot position spraying operation in the open workshop of great area, can lead to waste gas can not obtain completely to be handled, can cause the pollution to the environment after the waste gas that does not handle through exhaust-gas treatment equipment directly discharges into the atmosphere like this.
In order to prevent the atmosphere pollution caused by the direct discharge of untreated waste gas in a spraying workshop, in the prior art, air extraction equipment distributed on a plurality of operation points in the workshop is adopted for extracting air, polluted gas extracted by axial flow fans of the air extraction equipment enters a large-power waste gas treatment equipment body through a flexible pipe (the rear side end of a matched axial flow fan shell of each air extraction equipment is of a sealed structure, the rear side end of the axial flow fan shell is sealed by a sealing plate, a front connecting pipe is welded on the right side of an opening in the middle of a sealing plate at the rear side end of the shell, one end of the flexible pipe is inserted into the outer side of the front connecting pipe of each set of air extraction equipment, a rear connecting pipe is inserted into the other end of the flexible pipe, a flange is welded on the right side of the rear connecting pipe, a plurality of flanges are arranged at an air inlet pipe of the large-power waste gas treatment equipment, the waste gas of many air exhaust equipment outputs gets into in the exhaust-gas treatment equipment simultaneously and carries out purification treatment), then the exhaust-gas treatment equipment body of great power discharges into the atmosphere after with waste gas innocent treatment to reach better exhaust-gas treatment effect.
