Varnish filter

Abstract

The invention provides a varnish filter, which comprises a shell. An air inlet, an air distribution device, a baffle interception layer, a combined filtration net and an air outlet are arranged on the shell sequentially from the front end to the back end; a varnish collection tank is arranged at the bottom in the shell; a varnish discharge device is arranged at the bottom of the varnish collection tank; the baffle interception layer consists of a plurality of reverse V-shaped baffles which are separated at equal intervals and uniformly arranged in the shell from top to bottom; a protuberance is formed on the top of each of the reverse V-shaped baffles; the combined filtration net comprises two layers; the filtration net layer close to the air outlet consists of a plurality of layers of silk nets in different numbers, and the filtration net layer close to another air outlet is formed by combining a plurality of layers of fiber filter media of different densities. The varnish filter adopts multiple layers of intercepting and filtration devices to remove liquid oil dirt from varnish waste gas by grades; the intercepting and filtration devices adopt a drawable design, so the daily operation is convenient; the varnish filter occupies small space and is compact and rational in structure; the internal members can be exchanged easily without causing secondary pollution; and the purifying efficiency is high.

Description

【Technical field】 [0001] The invention belongs to the field of environmental protection products, and specifically refers to a varnish filter. 【Background technique】 [0002] Varnish is a kind of synthetic resin. Now it usually refers to the surface is transparent and clear. It is made of base materials and additives, without any pigment. After the film is formed, the oil is shiny. It is a liquid that increases gloss, abrasion resistance and water resistance. As a transparent protective paint, its hardness and wear resistance are better than color paints, which play a protective role; as a hand-feel paint, its luminosity and brightness are very good, and it feels good to the touch, such as PU paint sprayed on silicone parts and plastic parts. The UV paint sprayed is this varnish. At present, varnish is widely used in household appliances, mobile phones, computers, glasses, printing and other industries. During the use of varnish, a large amount of waste gas pollutants will...

Problems solved by technology

[0003] Varnish waste gas liquid oils are very easy to solidify, which brings great difficulty to treatment. At present, there are two main treatment methods, namely dry filtration and wet filtration. Dry filtration generally only uses non-woven filter materials Oil removal is easy to block and frequent replacement. Wet filtration generally uses water curtain or packing washing system to remove oil. Because the water solubility of varnish is very poor, the treatment effect of this type of filter is not good, and it will cause secondary Pollution
