Paint spraying room paint treatment method

Abstract

The invention provides a paint treatment system and method for a paint spray booth. The paint treatment system is mainly technically characterized in that the system comprises air openings, air pipes, a paint treatment device and a draught fan. The paint treatment device is partitioned into a gas flow decelerating chamber, a gas washing chamber and a gas-liquid separating chamber. The gas flow decelerating chamber and the gas washing chamber are partitioned through a first partition plate, wherein the lower segment of the first partition plate is provided with a shutter air opening. The gas washing chamber and the gas-liquid separating chamber are partitioned through a second partition plate, wherein the upper segment of the second partition plate is provided with a shutter air opening. The top of the gas washing chamber is further provided with atomization spray heads. A first vertical hole plate and a second vertical hole plate are arranged inside the gas-liquid separating chamber in a partitioned manner. The first hole plate extends downwards from the top of the gas-liquid separating chamber, and the second hole plate extends upwards from the bottom of the gas-liquid separating chamber, so that a curved gas flow channel is formed in the gas-liquid separating chamber. Mist with paint is collected through the air openings, subjected to purification for multiple times through the paint treatment device and then discharged through the draught fan. The paint treatment system is simple in structure. The excellent purification effect can be achieved by controlling the air volume and the pressure of the draught fan. In addition, the paint treatment system is low in operation cost.

Description

technical field [0001] The invention relates to the technical field of paint-containing air purification treatment, in particular to a paint treatment method for a spray booth. Background technique [0002] The surface spraying process of automobiles, refrigerators, air conditioners, mobile phone casings and notebook accessories, etc. are all carried out in the spray booth. During the process of spraying objects with automatic painting robots and manual spray guns, part of the paint directly acts on the surface of the sprayed objects, and 30 %~70% of the paint enters the air in the form of paint mist, which seriously pollutes the surrounding air and the environment; water curtain spray booths are widely used in operations to purify the paint mist, but paint falling will form in the water curtain, On the one hand, it is easy to block the circulation pipeline, affect the normal operation of the purification system, and then affect the spraying quality; on the other hand, it wi...
