Waste gas treatment equipment refers to the use of different treatment processes: by recycling or removing, reducing the harmful components of exhaust gas emissions, to protect the environment, clean the air of a kind of environmental protection equipment, waste gas treatment equipment? Below with Xiaobian to understand the next in detail

Activated carbon adsorption device is a kind of dry waste gas treatment equipment, composed of box and adsorption unit, pipe installation, mainly through activated carbon to absorb organic waste gas molecules, so that it and gas mixture separation, to achieve the purpose of waste gas treatment.

Zeolite runner mainly uses the adsorption of zeolite to achieve the purpose of purification. The clean gas of volatile organic compounds adsorbed by zeolite is directly discharged into the atmosphere through the chimney. The wheel continues to rotate at the speed of 1-6 revolution per hour, and at the same time, the adsorbed volatile organic compounds are transferred to the desorption zone. A small stream of heated gas is used to desorbed volatile organic compounds in the desorbed zone. After desorbed, the zeolite runner rotates to the adsorption zone to continuously adsorb volatile organic gases. The deattached concentrated organic waste gas is sent to an incinerator where it is burned and converted into carbon dioxide and water vapor and released into the atmosphere.

Catalytic combustion equipment is a kind of purifying air equipment for treating industrial waste gas. It can be used for solvent purification of waste gas, characterized by flameless combustion, combustion control temperature is relatively low, plus less heat energy consumption.

rto regenerative incinerators oxidize the organic matter (VOCs) in the waste gas into the corresponding carbon dioxide and water at high temperatures, thus purifying the waste gas and recovering the heat released when the waste gas decomposes. The main structure of RTO is composed of combustion chamber, regenerator chamber and switching valve. It is a kind of treatment equipment with relatively high purification efficiency at present.

Spray scrubber, also known as wash tower, is a gas-liquid generating device. The exhaust gas is fully in contact with the liquid, and the solubility of the exhaust gas in the water or the chemical reaction is used to add drugs to reduce the concentration of the exhaust gas.

Cyclone scrubber is a filtration device designed with two layers of spray, one layer of spray two layers of cyclone sheet purification device three layers of cyclone sheet purification device, mainly used in the treatment of dust waste gas.

Pneumatic swirl tower, is based on the principle of technology and power technology, on the basis of the ordinary spray paint curtain cabinet embedded in the "pneumatic mixed flow exhaust gas purification" a for the viscous dust, oily dust industry waste gas treatment, fiber dust and other dry dust removal equipment can not deal with the conditions and development of a warm environmental protection waste gas purification equipment.

The filter cylinder dust collector is composed of the filter cylinder as the filter element or the pulse jet dust collector. It has the advantages of high dust removal efficiency and easy maintenance, so it is widely used, especially for the treatment of welding smoke, and a special welding smoke dust removal purifier has been formed.

Bag dust collector is composed of dust bag as filter element or pulse jet dust collector, the biggest difference with the filter cartridge dust collector is the difference of filter element.

The core function of plasma purifier is natural plasma, which uses the characteristics of dust removal, sterilization and detoxification of plasma itself to deal with waste gas.

Photocatalytic purifier can not only destroy pathogen highly, but also degrade volatile organic compounds rapidly and deeply. The dust removal rate is more than 95%, and the purification efficiency is much higher than the national standard.

Wet high voltage electrostatic dust removal equipment, is a kind of environmental protection equipment for waste gas and dust. It is the use of electricity to separate the dust ions in the gas dust removal equipment. Organic energy is not disorderly, dust removal effect is good.

Lampblack purifier is a lampblack exhaust gas treatment device. It is mainly used for the purification management of kitchen low-altitude emission lampblack.

Of course, there are other combined devices, such as activated carbon adsorption and catalytic combustion combination, zeolite runner and rto combination and so on.
