Spraying Industry

1. Industry Overview

As an important component of the manufacturing industry, the coating industry generates large amounts of gaseous pollutants during surface treatment processes. These pollutants primarily originate from key procedures such as spraying, drying, and curing, making the industry a key focus of monitoring by environmental protection authorities.

2. Solution

(1) Yingzhong Environmental Protection provides exhaust gas treatment equipment:

The main characteristics of organic waste gases generated in the spraying industry are large gas volumes, low concentrations, and high particulate matter content. In response to the different characteristics of waste gases produced by various processes, selective pre-treatment technologies such as particulate capture towers, condensation and cooling, and dry filtration are employed. For end-of-pipe treatment, technologies like zeolite rotary concentration, activated carbon adsorption, regenerative thermal oxidation, and catalytic oxidation are utilized.

 

(2) JULIAN Environmental Protection provides resource utilization and harmless disposal services for solid waste (hazardous waste):

● Hazardous wastes such as waste coatings, waste solvents, waste pretreatment liquids, and waste packaging materials: harmless incineration;

● Julian Group has a professional fleet of hazardous goods transport vehicles, enabling it to provide owners with timely transfer services.
