Combined type demisting device

Abstract

The invention relates to a combined demisting device, which includes fog trapping fillers and filler support beams arranged on the inner top of the desulfurization tower, and multiple parallel filler support beams are located at the bottom of the fog trap fillers to support the fog trap fillers; it also includes A plurality of drawer structures arranged between the filler support beams, the main body of the drawer structure is a thin-walled plate with trapezoidal waves, and the hypotenuses of the trapezoidal waves are evenly distributed with a plurality of through holes opened from the inside to the outside and obliquely downward; the drawers The structure can slide along the track structure on the packing support beam and be withdrawn from the desulfurization tower wall. The drawer structure in the present invention can remove the suspended sulfur carried in the gas phase at the top of the desulfurization tower, and can be conveniently taken out from the tower for cleaning, effectively preventing the plugging of the fog-catching filler at the top of the desulfurization tower, ensuring the normal operation of the system, and improving the efficiency of the desulfurization tower. Desulfurization efficiency, reduce labor costs.

Description

technical field [0001] The invention relates to a desulfurization tower in coking production, in particular to a combined demisting device suitable for the desulfurization tower in the HPF gas desulfurization process. Background technique [0002] HPF desulfurization is an oxidation desulfurization and decyanation technology with ammonia as the alkali source and HPF as the catalyst. This method has the characteristics of simple equipment, convenient and stable operation and high desulfurization efficiency, and has been popularized and applied in many coking enterprises. [0003] When the HPF method is used for desulfurization, the gas after desulfurization in the desulfurization tower contains mist droplets, and the mist droplets in the gas are usually removed by setting a mist-catching packing layer on the top of the desulfurization tower. However, because the suspended sulfur entrained in the gas will adhere to the surface of the mist trapping filler, after long-term accu...

AI Technical Summary

Problems solved by technology

However, because the suspended sulfur entrained in the gas will adhere to the surface of the mist trapping packing, after long-term accumulation to a certain thickness, the tower resistance will increase, the demisting efficiency and desulfurization efficiency will drop sharply, and even the tower will be blocked.

In actual production, it is necessary to stop production frequently, manually enter the tower to clean the mist trap packing, or even replace the mist trap packing, resulting in huge waste of manpower and material resources, seriously affecting the normal operation of the desulfurization process
