Industry summary

Industrial coating workshop is a major energy consumption and pollution source of industrial product manufacturing industry. Taking the automobile manufacturing industry as an example, the energy consumption in the coating production process accounts for about 70% of the total energy consumption of automobile production, and the three wastes produced in the coating workshop also account for more than 85% of the total energy consumption in the automobile production process, including VOC (volatile organic compounds), production wastewater, solid waste, etc. If these substances are discharged wantonly without necessary harmless treatment, it will inevitably bring serious pollution to the environment. Among the three kinds of coating wastes, VOC is the most difficult to treat and the most serious pollution to the environment.

Industry solutions

Source of VOCs：Automobile / machinery / ship / rail transit / motorcycle / container / furniture coating

Common components：benzene, toluene, xylene, ethylbenzene, cumene, ethyl acetate, butyl acetate, propyl acetate, ethylene glycol, butanol, butanone

Characteristics of exhaust gas：large air volume, low concentration, concentration fluctuation, and large dust volume

Solution：dust removal and filtration + zeolite concentration rotor + thermal oxidation (RTO/CO/RCO) + (extra heat utilization)

*Master the core materials, select the rotor accurately, purify 90% ~ 99% efficiently and reach the standard continuously

*Long service life, less replacement and maintenance, non-burning substrate, safer than activated carbon

*Modular non-standard equipment, faster supply, meet the requirements of environmental protection deadline

*More than 1000 cases, rich engineering experience, safe and reliable

*Perfect after-sales service system, advanced rotor testing equipment

Case 1：the largest order in domestic automobile spraying industry

Case 2：Huashijie helps a German automobile brand to successfully complete the replacement of the original imported rotor to Napotec rotor within a specified time limit, and our rotor can fully meet the requirements after the replacement

Case 3：Huashijie molecular sieve rotor +RTO equipment is adopted by a famous household overall kitchen brand
