Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an activated carbon organic waste gas purification device with a high adsorption rate. Background Art

[0002] Activated carbon is a kind of microcrystalline carbon material mainly made of carbon-containing materials. It has a black appearance, a well-developed internal pore structure, a large specific surface area, and a strong adsorption capacity. There are a large number of micropores in activated carbon materials that are invisible to the naked eye. The surface area of ​​the micropores in 1 gram of activated carbon material can be as high as 800-1500 square meters after unfolding, and it is even higher for special purposes. That is to say, in an activated carbon particle the size of a rice grain, the internal surface area of ​​the micropores may be equivalent to the size of a living room. It is these highly developed pore structures that give activated carbon excellent adsorption properties. Activated carbon uses the force of mutual adsorption between molecules to effectively adsorb various substances, including organic matter, odors, pigments, heavy metal ions, etc. This makes it an important material for treating wastewater, purifying air, and improving water quality.

[0003] An existing activated carbon organic waste gas purification device, such as an activated carbon adsorption device with patent number CN201911164816.7, adopts a partition plus a first cavity structure to place an activated carbon adsorption layer.

[0004] The above-mentioned prior art solutions have the following defects: when the activated carbon adsorption layer reaches the end of its service life, it is necessary to dismantle the partition and remove the activated carbon adsorption layer and refill it, and finally reinstall the partition before it can continue to be used. The whole installation process is very cumbersome and the efficiency needs to be improved. Utility Model Content
