Problems solved by technology

[0002] With the development of industrialization, more and more organic waste gas is discharged into the environment. At the same time, the types and quantities are becoming more and more complex, causing environmental pollution and seriously threatening human health. The effective purification of organic waste gas treatment has attracted more and more attention. At present, there are many methods and techniques for treating and purifying organic waste gas. Adsorption technology is widely adopted and applied due to its advantages of low energy consumption, high purification efficiency and strong practicability; activated carbon has abundant sources, low price and good adsorption performance. It is widely used in industry. The existing activated carbon adsorption process is only suitable for the treatment of low-concentration organic waste gas. High-concentration organic waste gas is easy to block activated carbon, which greatly shortens the service life of activated carbon. However, the process suitable for high-concentration organic waste gas has no effect on waste gas treatment. Good, often can not meet the discharge standards, resulting in environmental pollution

Embodiment 1

[0021] 1) Exhaust gas removal treatment

[0022] The exhaust gas is introduced by the fan to the bottom of the impurity removal tower, and moves from bottom to top. The top of the impurity removal tower is sprayed, and the water contacts the exhaust gas countercurrently from top to bottom. The exhaust gas continues to be introduced into the pre-cooling room by the fan, and the spray water falls into the storage tank. pool;

[0023] 2) Exhaust gas precooling

[0024] Exhaust gas enters the pre-cooling chamber, the wall of the pre-cooling chamber is provided with a jacket, and the cooling water circulates in the jacket from bottom to top to reduce the temperature of the pre-cooling chamber;

[0025] 3) Exhaust gas condensation

[0026] After the exhaust gas comes out of the pre-cooling chamber described in step 2), it enters the condensation chamber, and the organic matter in the exhaust gas condenses into a liquid state and is separated from the gas. The liquid organic matter...

Abstract

The invention discloses an activated carbon adsorption process in the technical field of exhaust gas adsorption. The process comprises the following steps: 1) exhaust gas impurity removal treatment, 2) exhaust gas pre-cooling, 3) exhaust gas condensation, 4) exhaust gas drying and 5) exhaust gas deep adsorption. The exhaust gas is pre-cooled in a pre-cooling chamber, which is favorable for the next exhaust gas condensation treatment; after the exhaust gas is condensed, the internal temperature of a condensing chamber is reduced to being the dew point of organic matter or lower in the exhaust gas, so that the organic matter is condensed into a liquid state to separate out and separate from the gas; at the moment, a small amount of harmful substances still exists in the exhaust gas, the amount of harmful substances in the exhaust gas can be further reduced through the deep adsorption of an activated carbon adsorption box in the activated carbon adsorption chamber, and the activated carbon adsorption box in the adsorption chamber is stacked in a way shaped like a vertical Chinese character tian, so that the adsorption surface of the activated carbon adsorption chamber is perpendicularto the incoming exhaust gas, and the adsorption area in the activated carbon adsorption chamber is maximized, thereby improving the adsorbability of the activated carbon adsorption chamber.
