Industry summary

Coating compound is mainly used for the production of surface coating process of film, paper, etc. This machine is to coat the rolled substrate (such as paper, cloth, leather, aluminum foil, plastic film, etc.) with a layer of glue, paint or ink with specific functions, and then roll it after drying. Because the adhesive needs to be diluted with organic solvent before coating, there will be deployment waste gas, coating waste gas and drying waste gas in the production process, which mainly contains organic pollutants.

Industry solutions

VOCs source：Coating machine, laminating machine

Common components：ethyl acetate, n-butyl acetate, acetone, butanone, etc

Characteristics of waste gas：large air volume, medium and low concentration, less dust

Solution：＜1500mg/m³，molecular sieve rotor + thermal oxidation (RTO / CO / RCO)

1500 ~ 2500mg / m³, regenerative thermal oxidation RTO

More than 2500mg / m³, single component, non water soluble solvent by steam adsorption recovery / water soluble solvent by nitrogen adsorption recovery

Case 1：A state-owned adhesive tape enterprise in Henan Province used Huashijie Rotor + RTO after the original adsorption and recovery equipment was struggling to meet the emission standard

Molecular sieve runner + thermal oxidation • Regenerative thermal oxidation RTO • Adsorption recovery
