Organic waste gas
Zeolite fixed bed adsorption desorption regeneration unit
The organic waste gas to be treated is led out from the air duct and then enters the dry filter to remove the water and then enters the activated carbon adsorption bed. The organic substances in the gas are adsorbed on the surface of the activated carbon by the activated carbon, so that the gas can be purified and emptied. When the adsorption bed is saturated, the catalytic combustion furnace will work, and high temperature gas will be discharged into the adsorption bed, so that the organic matter will be separated from the adsorption bed, and the carbon dioxide and water will be discharged after catalytic combustion.
Activated carbon adsorption steam recovery unit
The activated carbon adsorption steam recovery device is mainly applicable to the purification of low concentration gaseous pollutants. For high concentration organic gases, it is usually necessary to reduce the concentration through condensation and other processes before adsorption purification. After the activated carbon has been adsorbed for a period of time, it is saturated and cannot normally adsorb the solvent. At this time, it is necessary to desorb the activated carbon. The desorbed medium steam and the organic waste gas desorbed from the steam are condensed and recycled by the condenser. This technology is a classic and commonly used gas purification technology.
RCO equipment can be directly applied to the purification of organic waste gas with medium and high concentrations (1000mg/m3 to 10000mg/m3). RCO equipment can also be applied to the activated carbon adsorption concentration catalytic combustion system to replace catalytic combustion and heater.
VOCs waste gas can be effectively adsorbed in the zeolite after passing through the hydrophobic zeolite concentration runner to achieve the purpose of removal. The clean gas of volatile organic compounds adsorbed by the zeolite is directly discharged into the atmosphere through the chimney. The runner rotates continuously at the speed of 1-6 revolutions per hour, while the adsorbed volatile organic compounds are transmitted to the desorption area. A small stream of heated gas is used in the desorption area to desorb volatile organic compounds, and the desorbed zeolite wheel rotates to the adsorption area to continuously adsorb volatile organic gases. The concentrated organic waste gas after desorption is sent to the incinerator for combustion and conversion into carbon dioxide and water vapor and discharged into the atmosphere.
Types of organic waste gas applicable to environmental protection equipment: alkanes, olefins, alcohols, ketones, ethers, esters, aromatics, benzene and other hydrocarbon organic waste gases; Low concentration of organics (lower than 25% LFL), large air volume;
Odor gas biological treatment device
The odor gas biological treatment device is a system that relies on microorganisms growing on the filler carrier to treat VOC. Microbes grow on the filter media in the form of biofilm, and the mass transfer and degradation of VOC substances are carried out in the same reactor. The spray circulation system above the bio bed filler circulates the liquid phase. The equipment is equipped with fillers attached with microorganisms. Due to the existence of carriers, the biomass of microorganisms increases, and the gas-liquid contact efficiency is high, which can achieve the goal of efficient removal. The microbial treatment method also has high treatment efficiency for hydrogen sulfide, chlorinated organics, toluene, etc. As long as the microorganisms are "inoculated" on the surface of the appropriate carrier filter material, the odor can be purified by controlling the conditions suitable for the growth of microorganisms and passing through.
