HYDRAULIC SEAL OF WET GAS CLEANING SYSTEM

摘要

FIELD: technological processes. ^ SUBSTANCE: invention is intended to prevent air suction in the system of wet gas cleaning in process of slurry liquid drain from it and may be used in metallurgy and other industries. Hydraulic seal comprises cylindrical vessel 1 with conical bottom 2, nozzle for supply of slurry liquid 3, nozzle to drain slurry liquid arranged over nozzle for slurry liquid supply, scraper device 5 and pipeline for drain of slurry pulp 9. Bottom is equipped with hydraulic nozzle 7 for drain of slurry pulp installed coaxially to axis of vessel. Nozzle with formation of inner circular channel is enclosed into external jacket 8 arranged coaxially to it, upper part of which is coupled with conical bottom, and lower one is connected to pipeline of slurry pulp drain. Nozzle jacket is provided with air duct 10, lower part of which is coupled with upper part of external jacket of nozzle, and upper one is arranged higher than nozzle for drain of slurry liquid. ^ EFFECT: increased efficiency of slurry pulp drain, prevention of air suction into system of wet gas cleaning, increased reliability and durability of hydraulic seal operation, simplified maintenance of hydraulic seal elements. ^ 3 cl, 1 dwg
