Integrated purification system for painting waste gas, waste water and waste residues

Abstract

The invention discloses an integrated purification system for painting waste gas, waste water and waste residues, which comprises an acid purification tower, an alkali purification tower, a waste gas adsorption device, a waste liquid primary filter, a waste liquid deep filter, a waste gas purifier and a sludge compression tank, and all devices are connected by pipelines, wherein the acid purification tower is provided with a waste gas inlet and a waste water and waste residue inlet, the waste gas inlet is located at the upper end of the acid purification tower, and the waste water and waste residue inlet is located at the lower end of the acid purification tower. The integrated purification system is low in manufacturing cost, simple in structure and good in purification effect, and can make the painting work environment standard completely.

Description

technical field [0001] The invention relates to the field of painting automation, in particular to an integrated purification system for waste gas, waste water and waste residue in the painting industry. Background technique [0002] The coating industry is an important branch of modern industry. Most industrial products have to be surface treated, powder coated, and painted to make the products anti-corrosion, anti-rust, and beautiful. However, the coating industry is also a heavily polluting industry. During the painting process, it is often accompanied by the generation of organic waste gas, waste liquid, paint mist, and waste residue. Nowadays, the requirements for environmental protection are getting higher and higher. The traditional three-waste purification devices mostly use cement pools, which cannot be moved and can only be used for It is used in a single project, and the original product can only have a single function of waste gas or waste water treatment, and do...

[0002] The coating industry is an important branch of modern industry. Most industrial products have to be surface treated, powder coated, and painted to make the products anti-corrosion, anti-rust, and beautiful. However, the coating industry is also a heavily polluting industry. During the painting process, it is often accompanied by the generation of organic waste gas, waste liquid, paint mist, and waste residue. Nowadays, the requirements for environmental protection are getting higher and higher. The traditional three-waste purification devices mostly use cement pools, which cannot be moved and can only be used for It is used in a single project, and the original product can only have a single function of waste gas or waste water treatment, and does not have dual or multiple functions. Therefore, the present invention provides an integrated purification system for waste gas, waste water and waste residue in the painting industry, which can remove dust , purify water quality, but also discharge solid particles such as paint blocks
