VOC Exhaust Treatment Equipment

VOC (volatile organic compounds) recovery device, as the key equipment for environmental treatment, adopts multi-stage composite purification technology to achieve efficient treatment of organic waste gas. Its core technology system includes the synergistic treatment process of gradient condensation separation and deep adsorption: through the multi-stage refrigeration system, the exhaust gas is cooled down step by step to the ultra-low temperature range of -70℃ to -110℃, so that the organic components with different boiling points can be liquefied and precipitated out in phases; at the same time, the configured adsorption module can be molecularly trapped for the residual gaseous pollutants, and the synergistic double effect ensures that the exhaust gas emission meets the stringent environmental protection standards of GB31571 and so on. standard.

    Equipment advantages

    The device innovatively adopts the composite process of refrigeration separation and freezing dehydration, integrated with intelligent temperature control system and anti-freezing and plugging design, which can dynamically adjust the cooling gradient and adsorption parameters according to the characteristics of the components of different projects and environmental emission standards. 
    The core advantages are reflected in: three-stage condensation system to achieve organic components of the directional liquefaction recovery, low-temperature crystallisation and dehydration module to ensure continuous and stable operation of the system, the end of the adsorption unit can be customised activated carbon or zeolite molecular sieve media to form a triple protection system, the overall recycling efficiency of up to 98% or more, much better than the industry average.

    Industrial application

    The system has been successfully applied to more than 20 key industries, such as automotive coating, pharmaceutical synthesis, thermal power generation, waste incineration, etc. It is especially outstanding in the scenarios of iron and steel smelting exhaust gas treatment, chemical VOCs recovery, and electronic precision manufacturing. It is especially suitable for the treatment of industrial waste gas containing benzene, halogenated hydrocarbons, ketones and other complex components, simultaneously realising the resource recovery of organic solvents and ultra-clean emission of exhaust gases, and constructing a green production system for the enterprise that gives equal weight to both environmental and economic benefits. The modular design can be flexibly adapted to the treatment scale of 5000-200000m³/h, and it has become the preferred technical solution for centralised treatment in industrial parks and ultra-low emission renovation in key industries.
