The device has the characteristics that the flow velocity and temperature of waste gas can be controlled, the moisture of the waste gas cannot be increased, particles can be filtered out, and activated carbon can be regenerated and recycled.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, in particular to a waste gas collection and purification device used in an activated carbon adsorption tower. Background technique [0002] Activated carbon adsorption tower is the best purification equipment for organic waste gas and odor treatment. Activated carbon adsorption is an effective measure to remove water odor, natural and synthetic dissolved organic matter, micro-pollutants, etc. Most of the relatively large organic molecules, aromatic compounds, halogenated alkynes, etc. can be firmly adsorbed on the surface or in the void of activated carbon, and have obvious removal effects on humus, synthetic organic matter and low molecular weight organic matter. Activated carbon adsorption is used as a deep purification process , often used in the final treatment of wastewater, and can also be used in the purification of long-term production water and domestic water.

Problems solved by technology

[0003] However, the adsorption efficiency of the activated carbon adsorption tower will be affected by the flow rate and temperature of the exhaust gas. If the temperature is too high, the activated carbon will be damaged. If the flow rate is too fast, the activated carbon will not have enough time to absorb harmful gases. The particles in the exhaust gas will block the pores of the activated carbon. Weaken the adsorption effect of activated carbon. The existing exhaust gas cooling equipment often uses water mist to cool down, but the water will be transferred to the activated carbon adsorption tower and absorbed by the activated carbon, which will weaken the adsorption effect of activated carbon. At the same time, activated carbon has adsorption saturation. After a period of time, the internal activated carbon needs to be replaced, which is time-consuming and labor-intensive, and the continuous replacement of activated carbon requires a lot of cost. However, the existing activated carbon regeneration often uses a regeneration method that damages the activated carbon in a hurry, which is not conducive to the recycling of activated carbon.
