no. 1 approach

[0025] Embodiment 1: The paint mist gas passes through the paint mist specific resistance regulator, and then enters the electrostatic separator after being tempered by the paint mist specific resistance regulator. The number of cyclone tempering ports of the paint mist ratio resistance regulator is set to 10. The gas enters the paint mist collector after being charged by the pulse high voltage generator with three-stage pulse, and the different pulse voltage peak values ​​of the pulse high voltage generator are set according to the density of the paint mist. The higher the density, the higher the pulse voltage. Otherwise, the pulse voltage is low. The anode plate of the mist collector is vertical, the anode plate has three high-voltage settings, and the inclination angle θ of the cathode plate is 15°. After being treated by the paint mist collector, the paint mist gas enters the curtain collector. The curtain collector has three layers of staggered collection tanks. The pain...

Abstract

The invention discloses a paint mist purifying device. The paint mist purifying device comprises a paint mist resistance conditioner, a static electricity separator, a paint mist catcher and a curtain collector and an outlet, wherein the paint mist resistance conditioner, the static electricity separator, the paint mist catcher and the curtain collector are communicated in sequence from top to bottom, and the curtain collector is also communicated with the outlet. Paint mist gas sequentially passes through the paint mist resistance conditioner, the static electricity separator, the paint mist catcher and the curtain collector, paint particles in the paint mist gas are separated from gas and are collected, and the gas is discharged from the outlet. According to the paint mist purifying device disclosed by the invention, firstly, the gas characteristics of the paint mist gas can be regulated, the electrical charge efficiency of the paint mist gas can be promoted, and the paint particles can be effectively captured by subsequently applying pulse high voltage, so that the purifying efficiency and the purifying effect of the paint mist purifying device can be promoted.

Description

technical field [0001] The invention relates to the field of painting technology, more specifically, to the purification treatment technology of paint mist. Background technique [0002] The painting process is widely used in the anticorrosion and decoration of the surface of metal, plastic, wood and other materials. When spraying paint, the paint is atomized by the high-speed rotation of the spray cup and the action of compressed air to form fine particles, which are sprayed on the surface of the workpiece through compressed air or / and electrostatic action. membrane. The paint mist generated during the surface coating process of the product needs to be treated before it can be discharged. The current treatment forms mainly include wet and dry methods. The dry treatment is to filter the paint mist through filter cotton or paper-based filter materials. Wet treatment is to filter the paint mist through water. Common structures include water cyclone, water curtain, pumpless wa...
