Abstract
The utility model discloses a wet process dedusting spraying pipe which belongs to the facilities of wet process dedusting equipment for coal gas. The wet process dedusting spraying pipe comprises a pipeline and is characterized in that a protective plate is arranged at the top part of the pipeline, the protective plate is an angle steel with an included angle no larger than 90 DEG and is welded by two steel plates, and the protective plate is welded with the pipeline into a whole. In the wet process dedusting spraying pipe, the tip end of the top angle of the protective plate faces the flowing direction of the coal gas flow, the tip end part plays a role of shunting when the coal gas passes through the part so as to reduce the washing force of the coal gas flow to the pipeline, reduce the abrasion of the spraying pipe and prolong the service life of the spraying pipe. The wet process dedusting spraying pipe has simple structure, low manufacture cost and good effect and is economical and applicable.
Description
Technical field
The utility model belongs to the facility of wet gas cleaning equipment, is specifically related to a kind of wet dedusting shower.
Background technology
Sprinkling system need be installed at the wet dedusting device interior by wet gas cleaning system of iron and steel enterprise, through sprinkling system a large amount of water of coal gas spray is lowered the temperature and dedusting, and finally obtaining dustiness is 10mg/m
3Following purified gas.This process is claimed wet dedusting.
The raw gas temperature of coming out from steelmaking furnace is high, dustiness is big, speed is fast, washes away shower incessantly, very easily wearing and tearing is caused on shower top; Behind the certain hour; The shower conduit upper is washed away worn out by coal gas stream, water is from the impaired site of perforation ejection of pipeline, the reduction of sprinkling system sprinkler pressure; Influence the dust collection capacity of wet dedusting equipment, caused gas purification defective and influence coal gas user's production.In addition, water can make the device interior air turbulence from the impaired site of perforation ejection of spray piping, causes device interior tube wall dust incrustation, reduction gas flue size.
In order to guarantee gas quality, rear portion coal gas consumer products quality is not caused detrimentally affect, dust-removal system must withdraw from maintenance within 3 months, change the shower that damages.
Summary of the invention
In order to solve the flimsy problem of wet gas cleaning device interior shower; Prolong the shower life cycle; Solve wet dedusting device interior tube wall dust scale problems; Reduce the dust removal installation internal passages and stop up the various losses that cause, the utility model provides a kind of work-ing life long a kind of wet dedusting shower.
The utility model comprises pipeline, it is characterized in that the top of pipeline is provided with protective shield, and it is the angle steel that is not more than 90 degree that protective shield is welded into angle by two block plates, and protective shield and pipeline welding are one.
The drift angle tip of the utility model protective shield is towards the flow direction of coal gas air-flow; Most advanced and sophisticated position is played shunting action during through this place at coal gas; Reduced the wash away dynamics of coal gas stream, thereby reduced the wearing and tearing of shower, the life cycle that has prolonged shower pipeline.
The utility model is simple in structure, and low cost of manufacture is effective, and is economic and practical.
