Description

Technical Field

[0001] The utility model relates to the technical field of coke oven gas treatment, in particular to a coke oven gas deoxidation and fine desulfurization device. Background Art

[0002] The discharge of coke oven gas into the atmosphere without treatment and utilization not only causes waste of resources but also causes huge pollution to the environment. Coke oven gas is a good raw material for synthesizing methanol, synthesizing ammonia and producing hydrogen.

[0003] For example, the "A Coke Oven Gas Deoxidation and Fine Desulfurization Device" with publication number CN215209278U includes a primary treatment mechanism and a secondary treatment mechanism. The primary treatment mechanism includes a primary desulfurization box and an air inlet arranged on the primary desulfurization box. A first catalyst layer and a cooling pipe are arranged inside the primary desulfurization box. Under the action of the first catalyst layer, the sulfide in the mixed gas reacts with hydrogen, and heat is released during the reaction to promote the reaction of hydrogen and oxygen. The initial reaction releases a lot of heat, and cooling water is introduced into the cooling pipe to cool the first catalyst layer to prevent the first catalyst layer from overheating and deteriorating and failing. When the gas catalyzed by the first catalyst layer continues to flow to the right, it catalyzes the reaction again through the second catalyst layer in the secondary treatment mechanism to further finely remove the sulfide and oxygen in the coke oven gas.

[0004] Although the above-mentioned desulfurization device has certain advantages in the desulfurization efficiency of coke oven gas, it still has certain disadvantages:

[0005] When the above-mentioned desulfurization device is used for desulfurization, the effect of the desulfurizer decreases after a period of use. In order not to affect the desulfurization efficiency, it needs to be replaced. However, the installation and replacement of the above-mentioned device is relatively troublesome and inconvenient to replace. At the same time, the desulfurizer is easy to accumulate in one piece during use, and the coke oven gas cannot be fully purified, which easily reduces the purification quality and is inconvenient to use.
