SU453194A1 - MULTICYCLONE FOR CLEANING GAS FROM DUST - Google Patents

Description

I

The invention relates to devices for the purification of gases from dust and can be used in the chemical, ore-dressing, construction, and other industries.

A multicyclone for cleaning gases from dust is known, comprising a housing with nozzles for inlet and outlet gases, divided by upper and lower tube sheets into chambers of dusty and cleaned gas, cyclone elements fixed between tube plates and a hopper partially filled with water. However, such a multicyclone does not provide high gas purification efficiency, since due to gas flows from one cyclone element to another, their normal operation is disturbed.

The proposed multi-cyclone is characterized in that in order to increase the cleaning efficiency by preventing gas from flowing over from one cyclone element to another, the bunker is provided with a cellular grid with a number of cells equal to the number of cyclone elements installed under the bottom tube plate and partially immersed in water.

FIG. 1 shows a part of the described multicyclone; in fig. 2 is the same; section A-A in FIG. one.

The multicyclone includes a housing 1 with inlet and outlet nozzles, divided

the upper tube plate and the lower tube plate 2 on the camera dusty and purified gas. Cyclone elements 4, exhaust pipes 5 passing through the upper floor plate into the clean gas chamber and discharge pipes 6 passed through the bottom pipe plate 2 to the hopper 7 partially filled with water are fixed between the tube plates in the chamber 3 of the dusty gas.

The space of the bunker directly below the bottom tube plate is divided by a cellular grid 8 into isolated cells 9, the number of which is equal to the number of cyclone elements 4, and the lower edge is cellular

lattice lowered into the water. The height I of the cellular lattice is related to the nominal diameter d of the cyclone element by

Multicyclone works as follows.

The dusty gas is introduced through the inlet to the chamber 3 of the dusty gas and is distributed to the cyclone elements 4, where it is cleaned from dust. The purified gas is led through the exhaust pipes 5 to the clean gas chamber and through the exhaust pipe to the atmosphere or to the consumer. The separated dust through the discharge pipes b gets into the bunker 7 and is captured by water. Due to the presence of the cellular grid 8, the discharge ports 6 of the cyclone elements 4 are isolated from one another, and their normal operation is not disturbed by the flow of gas from one cyclonic element to another. Subject of the Invention A multicyclone for cleaning gases from dust, comprising a housing with nozzles for inlet and outlet of gases, divided by upper and lower tube plates into chambers of dusty and purified gas, cyclone elements fixed between tube plates and a hopper partially filled with water, about ton l and because, in order to improve cleaning efficiency by preventing gas from flowing from one cyclone element to another, the bunker is equipped with a cellular grid with a number of cells equal to the number of cyclone elements under the lower tube plate and partially immersed in water.
