Coke oven gas desulfurization tower

Abstract

The invention relates to the field of desulfurization towers, in particular to a coke oven gas desulfurization tower which comprises a furnace body, an exhaust port is formed in the center of the top of the furnace body and communicated with the interior of the furnace body, an impurity outlet is formed in one side of the bottom end of the furnace body, and a pipeline is arranged on the furnace body and located above the impurity outlet. The coke oven gas desulfurization tower is used for overcoming the defects existing when an existing coke oven gas desulfurization tower is used in a special environment in which coal gas with high sulfur content is inconvenient to desulfurize in other modes, and the existing coal gas desulfurization tower used in the environment often adopts multiple times of desulfurization or conveys the coal gas to other desulfurization points for desulfurization. In the prior art, due to the fact that desulfurization is not thorough, new sulfides can be generated in coal gas if the desulfurization tower is placed for a long time, desulfurization is equivalent to useless work, resources are consumed, and sediment cleaning of an existing desulfurization tower is often very tedious, on one hand, cost expenditure can be increased, and on the other hand, desulfurization is not thorough, and new sulfides can be generated in coal gas if the desulfurization tower is placed for a long time.

Description

Technical field [0001] The present invention relates to the field of desulfurization tower, which is specifically a coke oven gas desulfurization tower. Background technique [0002] The desulfurization tower is a tower apparatus for desulfurization treatment of industrial exhaust gas. In the production of gas, the gas is desulfurized, and the existing gas desulfurization is mainly desulfurized by wet desulfurization. [0003] However, existing conventional coal gas desulfurization towers still have certain defects, especially for coke oven gas desulfurization towers in some special environments, such as: the gas containing more sulfur is not used in other ways In the desulfurization environment, the existing gas desulfurization towers used in such environments tend to use multiple desulfurization or transport gas to other deanfulfur out to make desulfurization. On the other hand, it will increase cost spending, on the other hand, the desulfurization is not thorough. If the place...

Problems solved by technology

[0003] However, the existing coke oven gas desulfurization towers still have certain defects in use, especially the coke oven gas desulfurization towers used in some special environments, such as: it is inconvenient to use other methods to desulfurize the gas with high sulfur content. In the desulfurization environment, the existing gas desulfurization towers used in such environments often use multiple desulfurization or transport the gas to other desulfurization points for desulfurization, which will increase the cost on the one hand, and on the other hand, desulfurization is not complete, If it is placed for too long, new sulfides will be produced in the gas, so desulfurization is equivalent to useless work and consumes a lot of resources. Secondly, the existing desulfurization towers are often very cumbersome to clean up the sediment. Therefore, we propose a coke oven Gas desulfurization tower is used to solve the above problems
