Wet desulfurization pulping system

Abstract

The invention discloses a wet desulfurization pulping system, which comprises a limestone powder bin and a pulping tank, the limestone powder bin is fixed on the ground through steel structure legs, the pulping tank is arranged vertically below the limestone powder bin, and the limestone There is a weighing feeder between the powder silo and the pulping tank, the lower part of the limestone powder silo is connected with the blanking hopper, the lower part of the blanking hopper is provided with a discharge valve, and the lower part of the slide valve or gate valve is provided with a lower flange. The upper part of the weighing feeder is provided with an upper flange, and the feeding valve is connected with the weighing feeder through the lower flange and the upper flange. The lower part of the weighing feeder is provided with a feeding pipe. The pipe is connected to the weighing feeder through the flange, and the feeding pipe extends downwards to the pulping tank. There is an agitator in the middle of the upper part of the pulping tank, and the pulping tank is located below the ground. The powder material of the present invention directly falls into the pulp supply tank located below, which can reduce the occupied area, shorten the conveying path, reduce investment and energy consumption, reduce the phenomenon of "secondary dust raising", and improve the on-site environment.

Description

technical field [0001] The invention relates to the technical field of wet desulfurization equipment, in particular to a wet desulfurization pulping system. Background technique [0002] Limestone (powder) gypsum wet desulfurization slurry supply system is composed of silo and its auxiliary equipment, feeding equipment, stirring slurry tank, slurry supply pump and other equipment. The material is fed by a valve or gate valve to a weighing screw feeder or a weighing belt feeder, and then transported to the pulping tank by a weighing screw feeder or a weighing belt feeder. The problems of this kind of pulping system are: first, it occupies a large area, and the investment and energy consumption are high; second, due to the long feeding path, the powder absorbs moisture and is easy to block, and secondary dust is caused by powder leakage. and higher investment in energy consumption. Contents of the invention [0003] The purpose of the present invention is to provide a wet ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a wet desulfurization pulping system to solve the above problems existing in the prior art; the present invention improves and simplifies the feeding process, the powder is fed by a rotary feeder, and concrete is set at the lower part of the silo In the mixing tank, the powder is directly dropped into the slurry supply tank below by the rotary feeder, which reduces the occupied area, shortens the conveying path, simplifies the feeding process, reduces investment, reduces energy consumption, and reduces " "Secondary dust" phenomenon and reduce equipment investment and energy consumption, improve the site environment, and avoid new pollution problems
