Experienced Manufacturers
Production plant area of more than 10,000 square feet, more than 100 people construction team.
Catalytic combustion machine is a dry filter + adsorption desorption + co catalytic combustion several processes encapsulated in one device, adsorption desorption generally use molecular sieve, also called molecular sieve adsorption desorption catalytic combustion machine. The main advantage of the equipment is simple installation and maintenance, covers an area of small, can be applied to the low concentration of waste gas treatment, strong adaptability, removal rate is relatively high, up to the national emission standards in various regions!

Process flow
①Pre-treatment:The organic waste gas with high air volume and low concentration (<800mg/m3) generated in the workshop is piped into the dry filtration and other supporting pre-treatment equipment.
②Adsorption and concentration: After pretreatment, VOCs gas is adsorbed on the surface of zeolite molecular sieve to provide high VOCs removal rate and meet the standards.
③ High temperature desorption + catalytic combustion (CO): VOCs in the exhaust gas is concentrated on the surface of the zeolite molecular sieve, the use of mixing heaters to provide about 150 ℃ small air volume of hot gas flow to carry out the reverse blowing desorption, desorption out of the high-concentration, small air volume concentration of the exhaust gas is sent to the catalytic combustion furnace (CO) within the catalytic combustion decomposition of CO2 and H2O, combustion of exothermic reuse, energy saving!
Working Principle
Organic waste gas into the dry filter pretreatment, through the molecular sieve adsorber, VOCs are porous zeolite molecular sieve adsorbent adsorption interception, discharge standards. After the adsorbent adsorption saturation, through the valve switch, the introduction of small air volume of hot air for high temperature blowing desorption, desorption out of the high concentration, small air volume concentration of waste gas, into the catalytic burner combustion treatment, the release of a large amount of heat and reuse system.
Process characteristics
1、Wide range of applications, advanced and mature process. It is at the international advanced technology level, and is one of the mainstream processes for the treatment of large-scale VOCs in the international industry. Applicable to most of the large air volume, low concentration of organic waste gas.
2, high processing efficiency, slow performance decay, can maintain high removal efficiency for a long time.
3、High safety coefficient, equipped with corresponding emergency measures. The adsorbent is non-flammable, using electric heater for temperature rise and desorption, no open flame.
4、Wide range of application, can deal with a variety of complex organic waste gas. A single set of integrated machine can be designed to deal with air volume of 10,000~40,000Nm3/h.
5、Low maintenance cost, high heat recovery efficiency, energy saving and environmental protection.
Scope of application
Automobile and parts manufacturing, hardware machinery manufacturing, furniture manufacturing, ink and paint manufacturing, printing, coating, pharmaceutical, chemical, PCB, semiconductor, electronics, toys, plastics, leather, shoes, rubber, textile printing and dyeing, and other industries, such as workshop generated by the large air volume of low concentration of VOC organic waste gas treatment.
It can treat the content of VCOs such as benzene, toluene, xylene, trisbenzene, styrene, via, alcohol, ether, phenol, ketone, ester, and so on.
