Abstract

The invention discloses a novel blast furnace gas hydrolysis conversion tower, and belongs to the technical field of blast furnace gas hydrolysis towers. The tower comprises a hydrolysis tower shell, the bottom of the hydrolysis tower shell is connected with a coal gas inlet pipe, a filler module is arranged in the hydrolysis tower shell, a lower bracket plate is arranged at the bottom of the filler module, and a middle bracket plate is arranged on the outer ring of the middle of the filler module; an upper flow guide device is arranged at the upper part of the filler module; and an upper pipe orifice device is arranged at the top of the hydrolysis tower shell. The hydrolysis catalyst filler is modularized, the coal gas flow is guided by adopting newly developed tower internals so that the coal gas flow uniformly and slowly passes through the hydrolysis catalyst, the contact area and the contact time of the coal gas and the hydrolysis catalyst are ensured, the hydrolysis catalysis efficiency is greatly improved, and meanwhile, the coal gas resistance pressure drop is reduced, and the requirements of blast furnace gas hydrolysis conversion are met.

Description

technical field [0001] The invention relates to the technical field of a blast furnace gas hydrolysis tower, and more specifically relates to a novel blast furnace gas hydrolysis conversion tower. Background technique [0002] Aiming at the problem of excessive SO2 after the combustion of blast furnace gas by-product in iron and steel enterprises, in the past, the method of end treatment was adopted, that is, the flue gas after blast furnace gas combustion was desulfurized. With the adjustment of the national industrial policy, the requirements for SO2 emissions have been greatly increased, and the terminal treatment can no longer meet the emission requirements. This requires iron and steel enterprises to realize desulfurization of blast furnace gas from the source. [0003] The fine desulfurization device at the source of blast furnace gas is generally equipped with a hydrolysis tower at the front end of the desulfurization tower. The hydrolysis tower is filled with a hydro...
