Multistage water spinning paint spraying cabinet

Abstract

The invention belongs to the technical field of waste gas treatment equipment, and particularly relates to a multistage water spinning paint spraying cabinet. The multistage water spinning paint spraying cabinet comprises a paint spraying chamber and a reaction chamber. The paint spraying chamber communicates with the reaction chamber through vent holes. A fan is arranged on the reaction chamber.A water outlet trough is arranged above an air inlet chamber. Liquid in the water outlet trough flows out, and a water curtain is formed. The vent holes are formed below the water curtain. The at least two sets of independent vent holes are formed in a cabinet body, the water outlet trough corresponding to the vent holes is arranged in the cabinet body, and a sealing plate used for sealing the vent holes is arranged in the cabinet body. Spraying devices and baffles are arranged in the reaction chamber, the baffles divide the reaction chamber into an S-shaped air flow channel, and liquid sprayed in the spraying devices forms water curtains on the baffles. A filter water trough is arranged at the bottom of the reaction chamber, and the liquid on the baffles is guided into the filter water trough through the baffles. The multistage water spinning paint spraying cabinet is good in cleaning effect, convenient to use and control and capable of being flexibly used conveniently.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment equipment, in particular to a multi-stage water cyclone paint spray cabinet. Background technique [0002] Spraying is a common method of using paint. When using it, the paint is dispersed into uniform and fine droplets by means of air pressure through a spray gun, and then applied to the surface of the object to be coated. The construction period of spraying is relatively short. A large area of ​​material can be loaded in a short time, which is convenient for mass production, and the surface of the product produced by the spraying process is smooth and delicate, so it is widely used in industrial production, but the paint is atomized during the spraying process, and the atomized paint Most of them adhere to the surface of the product, but some of the paint escapes in the air. Some of these paints will adhere to the machine, affecting the normal use of the machine, and some will be inh...

[0002] Spraying is a common method of using paint. When using it, the paint is dispersed into uniform and fine droplets by means of air pressure through a spray gun, and then applied to the surface of the object to be coated. The construction period of spraying is relatively short. A large area of ​​material can be loaded in a short time, which is convenient for mass production, and the surface of the product produced by the spraying process is smooth and delicate, so it is widely used in industrial production, but the paint is atomized during the spraying process, and the atomized paint Most of them adhere to the surface of the product, but some of the paint escapes in the air. Some of these paints will adhere to the machine, affecting the normal use of the machine, and some will be inhaled by the workers, affecting the health of the workers. So now Most of the factories spray paint in the paint spray cabinet, and the paint spray cabinet is equipped with a paint waste gas treatment device to absorb and process the paint in the air. A common paint spray cabinet is a water curtain paint spray cabinet published by the Chinese invention patent CN201720905228.4. Simple, use the exhaust gas to contact the water curtain and make the paint react with the liquid medicine in the water curtain to complete the cleaning of the exhaust gas. However, the contact time between the exhaust gas and the water curtain in this kind of spray booth is short, and the paint in the exhaust gas cannot be completely cleaned. , need other equipment to clean up exhaust gas repeatedly
