The invention discloses a novel dry-method horizontal desulfurization tower for blast furnace gas, relates to the technical field of desulfurization of blast furnace gas, and aims to solve the problems of high desulfurization resistance and complex equipment caused by adopting a multi-layer packed tower for blast furnace gas. The tower comprises a tower body, a blast furnace gas inlet pipe, a blast furnace gas outlet pipe, a desorbed gas inlet pipe and a desorbed gas outlet pipe, a plurality of adsorption chambers are sequentially arranged in the tower body from one side to the other side, a partition plate is vertically arranged between every two adjacent adsorption chambers, an adsorption layer is vertically and fixedly arranged in each adsorption chamber, an adsorbent is contained in each adsorption layer, a first gas port and a second gas port are formed in the two sides, located on the adsorption layer, of each adsorption chamber respectively, the first gas ports are located at the upper end of the tower body, the second gas ports are located at the lower end of the tower body, the first gas ports communicate with a blast furnace gas inlet pipe and a desorbed gas outlet pipe, and the second gas ports communicate with a blast furnace gas outlet pipe and a desorbed gas inlet pipe; and the tower is simple, low in resistance and good in desulfurization effect.
Description
technical field [0001] The invention relates to the technical field of blast furnace gas desulfurization, in particular to a novel dry-process horizontal desulfurization tower for blast furnace gas. Background technique [0002] Most of the sulfur in blast furnace gas is H 2 The form of S exists, while the H 2 S is converted to SO after combustion of gas 2 , endangering people's living environment, aiming at SO 2 For the problem of exceeding the standard, in the past, the method of terminal treatment was adopted, that is, the flue gas after blast furnace gas combustion was desulfurized. With the adjustment of the national industrial policy, the SO 2 The emission requirements of the blast furnace gas have been greatly increased, and the terminal treatment can no longer meet the emission requirements. This requires iron and steel enterprises to realize the fine desulfurization of the blast furnace gas from the source, and the H in the generator gas 2 The degree of S remov...
