In addition to the design and improvement of the system, the auxiliary equipment is complete, the purification efficiency is high, and the automation degree is high. Industrial dust remover can be widely used in petroleum, chemical, rubber, coating, printing and other industries, such as benzene and other organic waste gas can be purified.
Two, structure and working principle:
1, structure:
Mainly by the activated carbon adsorption purification device, desorption purification device, adsorption fan, desorption fan and other components.
2, working principle:
The adsorption process on the solid surface: because there is not balance and unsaturated molecular attraction or chemical bonding force, so when the solid surface in contact with the gas, can attract the gas molecules, the concentration and remained in the solid surface, this phenomenon is known as adsorption. Adsorption capacity of solid surface, so that the exhaust gas and the large surface of the porous solid material contact, waste gas in the adsorption on the solid surface, so that it is separated from the gas mixture, to achieve the purpose of purification. The essence is a process of adsorption and concentration. It is a physical process, which is a physical process, which is a physical process, and the subsequent selective catalytic combustion desorption or steam desorption regeneration device is based on the different exhaust components.
Catalytic combustion: desorption by organic solvent adsorbed by activated carbon catalytic combustion in hot air, so as to reach the boiling point of the solvent, the organic solvent out of activated carbon, and the high concentration of exhaust gas into catalytic combustion reactor. In the catalytic combustion temperature, the oxidation reaction is converted into harmless water and two carbon carbon into the atmosphere by the catalyst. Is a chemical reaction process. Is not an open flame combustion, and can completely solve the two pollution when desorption.
Desorption process: the steam from the tower bottom spray, the adsorption of activated carbon in the solvent evaporated, and then condensed by the condenser into liquid into the separation tube, the separation and recovery of organic solvent, the residual liquid discharged by the pump into the aeration, aeration. Is a physical process, can be recycled solvent, cost savings.
Activated carbon adsorption catalytic combustion desorption is a combination of the advantages of adsorption and catalytic combustion. The first use of activated carbon adsorption concentration, when activated carbon adsorption reached saturation, the use of electric heating starting catalytic combustion equipment, and the use of hot air heating activated carbon adsorption, catalytic combustion reaction bed when heated to 250 DEG C, activated carbon adsorption bed local reach 60 ~ 110 DEG C, from high concentration gas adsorption the bed can be desorbed in the catalytic oxidation reaction in the reaction bed. After the reaction, the high temperature gas passes through the heat exchanger, and a part of the heat exchange gas is sent back to the activated carbon adsorption bed to take off, and the other part is discharged into the atmosphere. The exhaust gas from the exhaust gas is heated by the heat exchanger and the temperature is increased. In this way, the catalytic combustion device and the desorption can reach the small power or no power operation.
Three, performance characteristics:
Running process does not produce two pollution;
Equipment investment is low, operation cost is low;
Stable performance, can also handle a variety of mixed gas, the purification efficiency is more than 95%;
With the advantages of low resistance, long service life and high purification efficiency, a new type of activated carbon adsorption material is used as adsorbent;
Product service: according to the characteristics of waste gas treatment and customer demand, the case design customization.
Four, the scope of application:
Activated carbon deodorizing filter used in large flow and low concentration organic waste gas treatment, treatment of benzene, ketones, alcohols, ethers and alkanes and mixed organic waste gas, mainly used for purifying harmful gas in chemical industry, machinery, electronics, electrical appliances, footwear, rubber, coating, plastics, printing and industrial production workshop all the
