What gases are treated in Industrial Waste Gas Treatment Equipment?

Industrial waste gas treatment equipment is activated carbon adsorption tower, is mainly activated carbon. It is black powdery or blocky, granular, honeycomb amorphous carbon, and there is also a regular arrangement of crystalline carbon. Activated carbon can effectively remove odors in wastewater treatment. Strange smell. Improve color, and all kinds of impurities in the water, such as chlorine, phenol, mercury, lead, arsenic, ammonia and nitride. Detergents, pesticides and other harmful substances have a high removal rate. For example, it has a good adsorption effect on benzene, alcohol, ketone, ester and gasoline organic solvent exhaust gas in exhaust gas treatment equipment.

The purification principle of the industrial waste gas treatment equipment is that the organic exhaust gas enters the activated carbon adsorber tower under positive or negative pressure. Due to the unbalanced and unsaturated molecular gravity on the solid surface of activated carbon, when the solid surface comes into contact with the gas, it can attract gas molecules, condensate and maintain the solid surface, and pollutants After being adsorbed, the exhaust gas enters the dust discharge system of the equipment after the filter, and the purification gas is discharged at high altitude.Using the characteristics of activated carbon such as pores and huge surface tension, the organic solvent in the exhaust gas is adsorbed to purify the exhaust gas.After the adsorption saturation of activated carbon, activated carbon needs to be regenerated, that is, under the premise of using physical or chemical methods without destroying its original structure, the adsorbent adsorbed on the micropores of activated carbon is removed, and its adsorption performance is restored, which is convenient for reuse. In the waste gas treatment equipment of activated carbon adsorption tower, it is important to master the regeneration method of activated carbon. The regeneration performance of activated carbon has been improved, and the service life and treatment effect of exhaust gas treatment equipment will be more durable.

Thermal regeneration is a commonly used method to treat the regeneration of activated carbon. At present, the thermal regeneration method is the most mature technology, with high treatment effect, regeneration time and a wide range of applications. However, it should be noted that the high-temperature heating regeneration device should solve the mutual bonding of carbon particles, and the sintering should pay attention to the blockage of the channel. Activated carbon regeneration methods also include catalytic wet oxidation, solvent regeneration, wet air oxidation regeneration, etc.

What is the process of industrial exhaust gas treatment facilities?

Volatile organic gas first undergoes a certain pretreatment device, and then further removes the impurities in the exhaust gas through the filter to ensure that these impurities do not occupy the pores of the activated carbon fiber, affecting the adsorption efficiency and service life of the activated carbon fiber; the filtered exhaust gas is introduced into the adsorption equipment through the fan.

The activated carbon fiber that adsorbs a certain amount of organic solvent is desorbed with saturated water vapor. After the desorption is completed, the filtered external air is sent into the adsorber for drying by the fan, so that the activated carbon fiber bed layer cools and removes residual steam, so that the activated carbon fiber maintains a high adsorption efficiency. The dried adsorber enters the next working procedure cycle for adsorption.

The desucted mixed steam containing organic matter enters the condenser for primary condensation. The condensate is then cooled by the plate condenser. The condensed organic matter and condensate enter the layered tank. After gravity stratification, the organic matter in the upper layer automatically overflows to the storage tank, and then sent to the adsorption recovery equipment by conveying pump; the condensate of the lower layer is discharged into Wastewater treatment system.
