The post-treatment facility of the bag dust collector refers to the facility for treating the waste gas and waste residue generated in the working process of the bag dust collector, with the purpose of reducing the pollution to the environment and protecting the environment and human health. It mainly includes several treatment methods.

1, activated carbon adsorption method: activated carbon adsorption method is the use of activated carbon to absorb organic matter in the exhaust gas, so that it can achieve the effect of purification, and the gas emissions after purification are extremely clean. In particular, the effect of organic waste gas treatment is very obvious, but the operating cost is high.

2, ozone oxidation method: ozone oxidation method is to inject ozone gas into the exhaust gas, ozone is absorbed, will react with organic matter and oxide in the exhaust gas, degrade the diffusible oxygen, to achieve the purpose of purifying the exhaust gas. When using, it is necessary to master the concentration of ozone and treatment time.

3, condensation method: condensation method is to cool the exhaust gas below the dew point, so that the water vapor in the exhaust gas is converted from gas to liquid, so that some harmful substances in the exhaust gas are separated and purified. However, replace and clean the device frequently. Otherwise, the condensation effect will be reduced.

4, catalytic oxidation method: catalytic oxidation method is a way to convert organic matter and oxygen into water and carbon dioxide through the catalyst, which is an efficient waste gas purification method. The selection of the catalyst needs to be selected according to different exhaust gas components, and attention needs to be paid to the management and maintenance of the catalyst.

5. biological filter bed method: biological filter bed method is the use of biological bacteria to degrade pollutants in the waste gas into harmless substances, is an environmentally friendly waste gas purification method. However, it is necessary to pay attention to the control of the humidity, temperature, PH value and oxygen content of the biofilter, as well as the regular replacement of bacteria and cleaning equipment.

6. Wet electric dust removal method: wet electric dust removal method is a method to remove charged particles from the exhaust gas by spraying water, which has the characteristics of good dust removal effect, low energy consumption and remarkable purification effect. However, the waste residue and water in the effluent have a high demand for treatment.

To sum up, there are a variety of methods for the post-treatment facility of the bag dust collector to choose from, and the specific method selection needs to be considered according to the actual situation, cost, purification effect and convenience of operation and maintenance. At the same time, the post-processing facilities should be scientifically managed and maintained to ensure that the facilities are in good working condition to achieve the purpose of purifying waste gas and protecting the environment.
