Method for conveniently changing activated carbon grid of activated carbon adsorption tower

Abstract

The invention relates to a method for conveniently changing an activated carbon grid of an activated carbon adsorption tower. The activated carbon adsorption tower comprises a tower body (1), wherein an activated carbon adsorption layer (2) and a spraying device (3) are arranged in the tower body (1); the spraying device (3) is arranged at the upper part of the activated carbon adsorption layer (2); the activated carbon adsorption layer comprises the activated carbon grid (21) and activated carbon (22); one part of the activated carbon grid (21) is connected onto the inner wall of the tower body (1), and the other part of the activated carbon grid (21) is connected with an annular plate (23); the activated carbon grid (21) can be taken out of the tower body (1) based on the annular plate (23). Through the design of the annular plate, the activated carbon grid can be conveniently changed.

Description

technical field [0001] The invention relates to the field of exhaust gas purification devices, in particular to a method for easily replacing activated carbon grids of an activated carbon adsorption tower. Background technique [0002] The existing activated carbon adsorption tower is equipped with an activated carbon adsorption layer, through which the exhaust gas generated in industrial production is adsorbed and purified, so as to meet the increasingly stringent air emission standards. However, during the adsorption process, activated carbon will adsorb exhaust gas in a saturated state, resulting in a decrease in adsorption efficiency, a decrease in adsorption capacity or failure, which in turn reduces the purification efficiency of exhaust gas and affects the purification ability of exhaust gas. In view of the above defects, the staff need to replace the activated carbon material regularly during the purification process, so the utilization rate of activated carbon is lo...

AI Technical Summary

Problems solved by technology

However, during the adsorption process, the exhaust gas adsorbed by activated carbon will be in a saturated state, resulting in a decrease in adsorption efficiency, a decrease in adsorption capacity or failure, which in turn reduces the purification efficiency of exhaust gas and affects the purification ability of exhaust gas.

In view of the above defects, the staff need to replace the activated carbon material regularly during the purification process, so the utilization rate of activated carbon is low and the production cost is high

[0003] Chinese invention patent application (publication number CN103495327A) discloses a kind of activated carbon adsorption tower, comprises tower body, is provided with activated carbon adsorption layer in the tower body, is also provided with spraying device, and above-mentioned spraying device is located at the upper part of above-mentioned activated carbon adsorption, this application The regeneration of saturated activated carbon can be realized by installing a spray device in the tower, but it has the problem that the activated carbon grid is not easy to replace
