An integral mobile environment-friendly plasma spraying equipment and paint mist purification method

Abstract

The invention provides integral movable type environment-friendly plasma spraying equipment and a paint mist purification method. The integral movable type environment-friendly plasma spraying equipment mainly consists of a tunnel type room body, a walking device, an air supply system, a discharge filtration purification system and an atmospheric pressure detection alarm system. The paint mist purification method provided by the invention comprises driving the room body to a large type workpiece; turning on an illuminating system, the alarm system, air supply fans and plasma purification devices, and closing front and rear door curtains; and starting spraying operation. During the spraying process, a great deal of air is supplied into an air supply static pressure chamber, enters a spraying operation room after being subjected to flow equalization and high-efficiency filtration, and flows from top to bottom on the total cross section in a laminar flow way. Paint mist generated during the spraying process forms a gas mixture with the flowing air; under the action of gas flow, the gas mixture orderly passes through V-shaped filter paper, a paint mist carpet, a bag type filter and plasma purifiers; and finally, the gas mixture meets the discharge requirement and is discharged. The integral movable type environment-friendly plasma spraying equipment and the paint mist purification method are convenient to use; the gas can be directly discharged after reaching the standards; the uninterrupted continuous painting work of the large workpiece can be realized; the multi-space painting switching can be realized as well; the station limit is not generated; the production efficiency is high; and with the adoption of the integral movable type environment-friendly plasma spraying equipment and the paint mist purification method, the maximum weight of a coating product can reach 50T.

Description

technical field [0001] The invention relates to a spraying equipment and a paint mist purification method, which are used for purifying the paint mist generated during the spraying operation, especially the paint mist generated during the spraying of large workpieces. Background technique [0002] Spraying paint on the surface of various devices is mainly for the appearance of the device, or to protect the surface of the device. However, paint or paint is a highly polluting substance to the air. During the spraying process, the paint will be sprayed in the air to form flying paint. Part of the flying paint will sink to the ground and part of it will volatilize in the air. And produce a strong smell in the air, seriously pollute the air. According to the requirements, factories involved in spraying should build paint spraying pollution treatment devices. Many factories have special spraying booths, and the devices to be sprayed are moved in the spraying booth for spraying to...

AI Technical Summary

Problems solved by technology

[0003] Workpieces need to be moved in and out of the spray booth, so the spray booth is suitable for painting small items, but for some large factories, some workpieces that need to be sprayed are bulky or very heavy, and need to be moved by a workshop crane. It is difficult to operate, because the crane cannot directly hoist large-scale work into the spray booth, and it is very troublesome to carry large-scale workpieces once, which is time-consuming and labor-intensive, and forklifts cannot move large-scale workpieces, and paint mist is generated when large-scale workpieces are sprayed heavier and more to handle
