Embodiment 1

[0029] from figure 1 It can be seen that a novel blast furnace gas dechlorination and hydrolysis conversion integrated tower in this embodiment includes a tower body shell 1, the bottom of the tower body shell 1 is provided with an inlet gas distribution pipe 2, and the bottom of the tower body shell 1 A lower bracket plate 4 is provided, and flow guide holes 41 are spaced apart on the surface of the lower bracket plate 4 .

[0030] The middle part of the tower body shell 1 is provided with a middle bracket plate 5, and the middle bracket plate 5 divides the inside of the tower body shell 1 into two parts, which are respectively a hydrolysis tower body 11 and a dechlorination tower body 12, and the tower body shell Body 1 is made of Q345B material. The diameter and wall thickness of the tower body are calculated according to the amount of gas to be processed. The upper tower is a hydrolysis tower, and the lower tower is a dechlorination tower. Both the hydrolysis tower body 11...

Abstract

The invention discloses a novel blast furnace gas dechlorination and hydrolysis conversion integrated tower, and belongs to the technical field of blast furnace gas towers. The tower comprises a tower body shell, an inlet gas distribution pipe is arranged at the bottom of the tower body shell, a lower bracket plate is arranged at the bottom of the tower body shell, flow guide holes are formed in the plate face of the lower bracket plate at intervals, a middle bracket plate is arranged in the middle of the tower body shell, the middle bracket plate divides the interior of the tower body shell into a hydrolysis tower body and a dechlorination tower body, and filler modules are arranged in the hydrolysis tower body and the dechlorination tower body. The dechlorination and hydrolysis catalyst filler is modularized and convenient to mount and replace, the coal gas flow is guided by adopting a specific internal structure design, so that the coal gas flow passes through the dechlorination and hydrolysis catalyst sequentially, uniformly and slowly, the contact area and the contact time of the coal gas and the dechlorination and hydrolysis catalyst are ensured, and the resistance pressure drop of the coal gas is reduced while the dechlorination and hydrolysis catalysis efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of blast furnace gas towers, and more specifically relates to a novel blast furnace gas dechlorination and hydrolysis conversion integrated 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 blast furnace gas source fine desulfurization device generally has a dechlorination tower and a hydrolysis tower installed at the front end of the desulfurization tower. The dechlor...
