Adsorption purification principle and process flow:
Organic waste gas through the filter to remove solid particles, from the top down into the adsorption tank, organic carbon capture, adsorption and concentration, purification of air from the lower part of the tank through the main fan into the atmosphere.
When the adsorption of organic matter reached saturation state, activated carbon stopped breathing organic waste gas.Steam is sent up through the activated carbon bed for blowing off, and the organic matter is expelled from the activated carbon, that is, desorption.The activated carbon in the tank recovers its activity, namely regeneration.
3. Hot air drying and cooling:
After steam desorption of the activated carbon layer, about 80 ~ 90% of the vapor condensate, filled the inner pores of the activated carbon, so as to reduce the activity of the carbon layer.Therefore, hot air is introduced to dry the carbon layer.Then close the steam valve, re-enter the room temperature air, cooling to about 25℃, the activated carbon restored as before, ready for recycling.
4. Organic solvent recovery:
Using the characteristics of higher dew point temperature of organic solvent, the mixture of steam and organic solvent is introduced into the condenser to condense. The condensate enters the separator through the trap, and the solvent is lighter than water to separate and recycle.
5. Condensation water purification:
In order to ensure the purity of condensate water and avoid the condensate of organic solvent discharged into water body, the water after separation in the separator is fed into compressed air, so that the organic solution agent in water is fully released.The organic air expelled by the compressed air returns to the exhaust system and is re-adsorbed.The condensed water after purification is discharged into the sewer.
6. Continuous adsorption measures:
In the factory of continuous production, the adsorption system also needs to work continuously accordingly. In the design of the exhaust gas purification system, the two-tank series can be selected to use alternately for adsorption and regeneration.
7. Regeneration cycle:
The regeneration period should be determined according to the concentration of harmful gas in the exhaust after purification.When the concentration of harmful gas is close to the superstandard value, the adsorption should be stopped and the regeneration should be carried out.In the initial working phase of the system, the concentration of harmful gas at the outlet should be measured in time so as to grasp the reasonable adsorption regeneration cycle.
