Description

Module-connected rotary suction tower with activated carbon

The present invention relates to a module-connected rotary adsorption tower using activated carbon, and more particularly, a space for supplying activated carbon is divided into several compartments with a separation mesh and rotated while exhaust gas flows in and is adsorbed evenly over the entire surface, thereby discharging volatile organic compounds It relates to a module-connected rotary adsorption tower using activated carbon that can be used by determining the number of modules connected while connecting modules according to the amount of exhaust gas processed.

Modern society has been striving to improve national welfare and increase income due to the rapid industrial development since 1980.

In particular, volatile organic compounds called VOCs cause photochemical oxidation with nitrogen oxides (NOx) in the atmosphere by sunlight to increase ozone concentration on the ground and cause smog. It is highly harmful to the environment and indirectly contributes to global warming, so it is desirable to treat it before it is released into the atmosphere. Therefore, in various facilities that generate polluting gases such as VOCs, an adsorption tower that removes polluting gases by using a phenomenon in which fluid molecules come into contact with and adhere to a solid surface is used.

Such an adsorption tower is a facility that installs an adsorption layer filled with activated carbon particles inside the housing to adsorb and remove pollutants by passing the polluted gas through it. A horizontal planar adsorption tower used when the adsorption process is carried out by passing it from the bottom or from the bottom to the top and is used when the throughput is relatively small, and several adsorption layers are formed vertically so that the treatment capacity can be variably adjusted according to the height of the adsorption bed regardless of the floor area. It can be expanded and is classified as a vertical flat adsorption tower suitable for large-capacity treatment.

In the adsorption tower as described above, the life of the activated carbon filled in the adsorption layer has expired and the activated carbon is exchanged for use, but there are the following problems.

First, when exchanging such activated carbon, the expired activated carbon filled in the adsorption tower must first be discharged and collected through the side outlet. There was a problem that the health could be adversely affected by the dust.

Second, in large-scale facilities such as steel mills, since the size of the adsorption tower is very large, the operation must be stopped when exchanging the activated carbon, so it should be used for as long as possible.

Third, the activated carbon is supplied to the adsorption space in which the adsorption tower is installed, the gas generated during operation is supplied, and then the activated carbon and the adsorption space are adsorbed, and the purified gas is discharged through the exhaust port as it is, so the supplied gas is not uniformly in contact with the activated carbon in the adsorption space, so the purification function through the activated carbon cannot be uniformly performed, and this has a drawback in that the lifespan is shortened.

Fourth, the activated carbon for storing activated carbon is mainly formed in a cylindrical shape and supplies the activated carbon to the inside space separated from the outside, so it is not possible to supply the photocatalyst required for the activated carbon, so there is a limit to improving the gas decomposition ability of activated carbon There is a drawback that it cannot be used for a long time.

Fifth, since the power using electricity cannot be used in the adsorption tower, various functions using it are lost, so the application of various functions was a limitation.
