[0002] During the normal production of the coke oven, the coke oven gas needs to pass through the deoiling and denaphthalene tower. The deoiling denaphthalene tower is filled with coke to absorb impurities such as naphthalene, tar and dust in the coke oven gas. The coke in the deoiling denaphthalene tower is used for a period of time After a period of time, the adsorption capacity will fail due to saturation. At this time, the coke in the deoiler and naphthalene removal device needs to be replaced, but frequent replacement of coke will take up a lot of manpower, and will affect the production progress to varying degrees. The adsorption capacity of coke has not reached the level of scrapping, and it is directly replaced for scrapping treatment, which leads to low utilization rate of coke and waste

technical field [0001] The invention relates to the field of cleaning devices for deoiling and denaphthalene towers, in particular to a reverse gas cleaning device for deoiling and denaphthalene towers. Background technique [0002] During the normal production of the coke oven, the coke oven gas needs to pass through the deoiling and denaphthalene tower. The deoiling denaphthalene tower is filled with coke to absorb impurities such as naphthalene, tar and dust in the coke oven gas. The coke in the deoiling denaphthalene tower is used for a period of time After a period of time, the adsorption capacity will fail due to saturation. At this time, the coke in the deoiler and naphthalene removal device needs to be replaced, but frequent replacement of coke will take up a lot of manpower, and will affect the production progress to varying degrees. The adsorption capacity of coke has not reached the level of scrapping, and direct replacement for scrapping will result in a low util...
