With global warming becoming more and more serious, the ecological environment suffers great damage, exhaust gas treatment has been more and more national attention. At this stage, there are many exhaust gas treatment methods, in the choice of treatment methods, need to be based on many factors to decide, such as exhaust gas conditions, air volume, concentration, etc.. The following Everest blue editor for you to introduce several commonly used exhaust gas treatment methods, I hope it can help you.
Activated carbon adsorption method
Due to the unsaturated molecular bonds on the surface of activated carbon, activated carbon has a strong adsorption capacity, when the exhaust gas molecules come into contact with the activated carbon, organic waste gas will be adsorbed by the activated carbon, the filtered exhaust gas can achieve the emission standards, through the activated carbon concentration of highly concentrated exhaust gas, can be purified by combustion of exhaust gas treatment equipment combustion, such as catalytic combustion, RCO, RTO.
Regenerative catalytic combustion
Thermal regenerative catalytic combustion equipment and thermal regenerative incinerator are a kind of thermal regenerative combustion equipment, according to the number of different rooms of the thermal regenerative body and two-chamber, three-chamber, five-chamber, seven-chamber thermal regenerative combustion equipment. Regenerative waste gas treatment method does not require additional fuel combustion, so it is a very energy-saving waste gas treatment equipment.
Liquid washing to purify exhaust gas
Corresponding equipment is the waste gas purification tower, the import of waste gas in the bottom of the waste gas purification tower, from the bottom up through the tower, through a single layer or multi-layer packing, the waste gas absorption purification treatment, clean waste gas will be discharged through the top of the tower above the discharge system, the waste gas purification tower to deal with the waste gas mainly through the absorption of the liquid and the waste gas neutralisation reaction, to achieve the purpose of purification.
Chemical reaction method
The use of certain substances in the waste gas and the liquid produces a neutralisation reaction characteristics, to remove the polluting components of the gas. The common ones are acid and alkali washing method, chlorination washing method, hydrogen peroxide washing method. Advantages: can widely go out a variety of malodour gas, and achieve high removal efficiency; has strong manipulation.
Soil deodorisation method
Soil deodorisation mechanism can be mainly divided into physical adsorption and biological decomposition of two categories, water-soluble malodorous gases (such as amines, hydrogen sulphide, primary fatty acids, etc.) are absorbed by the water in the soil to remove the non-soluble odorous gases are physically adsorbed on the surface of the soil followed by microbial decomposition in the soil. Advantages: low maintenance costs, deodorant effect is commensurate with activated carbon.
UV ultraviolet method
The use of special high-energy, high-ozone UV ultraviolet beam irradiation of malodorous gases, change the molecular structure of malodorous gases, so that organic or inorganic polymer malodorous compounds molecular chain in the high-energy ultraviolet beam irradiation, degradation into low molecular compounds. Advantages: small footprint, lower operating costs, lower investment in equipment.
Low temperature plasma method
Under the action of the applied electric field, the electrons in the electrode space get energy to accelerate the movement, which triggers a series of complex physical and chemical reactions such as excitation, dissociation or ionisation, which makes the chemical bond of the odour-producing groups broken, and then through multi-stage purification to achieve the purpose of deodorisation. Advantages: simple process, simple operation, adapt to the gas temperature wide (-50 ~ 50 ℃).
Above is the introduction of several commonly used waste gas treatment methods, now more commonly used adsorption desorption + catalytic combustion and zeolite rotor concentration + rto incinerator combination of processes, if you do not know what kind of treatment can be used through the bottom of the contact information to consult with us Oh ~!
