Composition of activated carbon waste gas treatment equipment:
The equipment is mainly composed of: air inlet section, tower body, filter element, differential pressure gauge, air outlet section, etc.
Activated carbon waste gas treatment equipment is a kind of dry waste gas treatment equipment. The utility model is composed of a box body and an adsorption unit filled in the box body. According to the number of adsorption units and air volume, it can be divided into various specifications. Different fillers can be selected for the activated carbon waste gas treatment equipment to deal with different waste gas.
Waste gas introduction:
Only the real understanding of the need to deal with the waste gas can be better treated. The use of activated carbon waste gas treatment equipment can help us to better deal with the waste gas produced in industrial production to a certain extent.
One: colorless clear liquid. It smells like benzene. It has strong refraction. It can be mixed with ethanol, carbon disulfide and glacial acetic acid, very slightly soluble in water. The relative density is 0.866. Freezing point - 95 ℃. Boiling point 110.6 ℃. The refractive index is 1.4967. Flash point (closed cup) 4.4 ℃. Flammable. Vapor can form explosive mixture with air, the explosion limit is 1.2% - 7.0% (volume). Low toxicity, LD50 (rat, oral) 5000mg / kg. High concentration gas is anesthetic. It's irritating.
Two: colorless and transparent liquid; it is the product of two hydrogen substituted by methyl in benzene ring, and there are three kinds of isomers, i.e. o, m and P. in industry, two refers to the mixture of the above isomers. Two have pungent smell, inflammable, with ethanol, or can mix at will, insoluble in water. The boiling point is 137-140 ℃. Second, it belongs to low toxic chemicals
Technical introduction:
Activated carbon is often used for gas adsorption, separation and purification, solvent recovery, sugar solution, grease, glycerin, decolorizer. When the organic waste gas is powered by a fan, positive or negative pressure enters the tower body. Because there is unbalanced and unsaturated molecular gravity or chemical strength on the surface of activated carbon solid, when the solid surface contacts with the gas, it can attract gas The molecules make it concentrate and keep on the solid surface, and the pollutants and odors will be adsorbed. After the waste gas passes through the activated carbon adsorption tower, it will enter the dust discharge system of the equipment, and the purified gas will be discharged at a high altitude up to the standard.
After using the activated carbon for a period of time, a large amount of adsorbate has been adsorbed, which gradually tends to be saturated and loses its working ability. In serious cases, it will penetrate the filter layer, so the regeneration or replacement of the activated carbon should be carried out.
Application of activated carbon adsorption box in waste gas treatment of painting and painting:
Due to the low VOCs concentration and low emission temperature, the waste gas from automobile painting is generally treated by activated carbon adsorption, which is a mature, effective and low equipment cost process. Our company has used a kind of activated carbon adsorption catalytic integrated equipment, its principle is to use the combination process of adsorption concentration and catalytic combustion. The activated carbon adsorbs and concentrates VOCs, which can be reused after desorption. The desorbed concentrated VOCs can realize low-temperature combustion through the electric heating of catalyst, so as to achieve the purpose of pollutant treatment. The combustion hot air is recycled in the desorption of activated carbon, so as to achieve the purpose of energy saving.
Concept:
Activated carbon adsorption tower can also be called activated carbon adsorber, activated carbon adsorption filter and activated carbon adsorption tank. Syd-hxt series | activated carbon adsorption filter (tower) is an environmental protection equipment product developed and produced by our company for waste gas filtration and odor absorption. The tower body of activated carbon adsorption tower can be made of stainless steel, carbon steel, PP plate and other materials. The activated carbon adsorption tower has the advantages of high adsorption efficiency, wide application, convenient maintenance and simultaneous treatment of various mixed waste gas. The activated carbon has the functions of removing formaldehyde, benzene, TVOC and other harmful gases and eliminating Du and deodorization. The activated carbon adsorption tower is widely used in the production of electronic components, the production of electric pools (batteries), acid pickling, laboratory ventilation, metallurgy, chemical industry, medical Yao, coating In the treatment of organic waste gas, such as food and brewing, the purification of waste gas from paint spraying is widely used.
Advantages of activated carbon adsorption tower:
High adsorption efficiency and wide application;
Convenient maintenance, no technical requirements;
It can process many kinds of mixed waste gas at the same time
