Embodiment Construction

[0025] Such as figure 1 As shown, a new demisting device for a blast furnace gas desulfurization tower includes a gas outlet pipe 1 installed at the gas outlet on the upper part of the tower body, and also includes a defogging material 3, which is obliquely installed in the gas outlet pipe 1, and the upper end It is closer to the tower body than the lower end; the tower body and the air outlet pipe 1 are located at the upper end of the defogging material 3, and a maintenance manhole 6 is opened to facilitate inspection, cleaning and maintenance; all edges of the defogging material 3 are in contact with the inner wall of the air outlet pipe 1 , in order to facilitate installation and maintenance, a layer of steel wire mesh 2 is provided on both sides of the defogging material 3 for positioning and installation. The steel mesh 2 and the inner wall of the air outlet pipe 1 can be welded and fixed. It is more convenient to install the steel mesh 2 , just open the maintenance manho...

Abstract

The invention discloses a demisting device of a novel blast furnace gas desulfurization tower and the desulfurization tower, relates to the technical field of blast furnace gas desulfurization, and aims to solve the problem that the demisting device increases the resistance in the tower and affects the desulfurization effect of the blast furnace gas. The device comprises a gas outlet pipe mounted at a gas outlet in the upper part of a tower body and a demisting material which is obliquely mounted in the gas outlet pipe. The upper end of the demisting material is closer to the tower body than the lower end of the demisting material; each part of the edge of the demisting material is in contact with the inner wall of the gas outlet pipe, and the included angle between the demisting material and the vertical direction is 0-90 degrees; a liquid collecting funnel is arranged at the lower end of the gas outlet pipe and is positioned between the lower end of the demisting material and the tower body; and a liquid outlet for discharging liquid is formed in the lower end of the liquid collecting funnel; and the device is beneficial to reducing resistance and improving the blast furnace gas desulfurization efficiency.

Description

technical field [0001] The invention relates to the technical field of blast furnace gas desulfurization, in particular to a novel demisting device and desulfurization tower of a blast furnace gas desulfurization tower. 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 ...
