RU2286832C1 - Centrifugal gas washer - Google Patents

Abstract

FIELD: separation.

SUBSTANCE: centrifugal gas washer comprises housing, branch pipe for supplying dusted gas, branch pipe for discharging cleaned gas, spraying device, swirler, device for smoothing the flow, and slime collector. The spraying device is made of a hollow cylindrical chamber closed from one of the sides and having tangential longitudinal groove for discharging of fluid. The spray trap is mounted downstream of the means for smoothing the flow. The direction of swirling of the gas outflowing from the swirler is counter to that of the sprayed fluid outflowing from the spraying device.

EFFECT: enhanced efficiency and reliability.

Description

The invention relates to techniques for wet dust collection and can be used in chemical, textile, food, light and other industries for the purification of dusty gases.

The closest technical solution to the claimed object is a gas scrubber, known from the book of A. A. Rusanov. A guide to dust and ash collection. M., - Energoatomizdat, - 1983, p. 112, Fig. 4.35 (prototype), comprising a housing, a pipe for introducing dusty gas, a pipe for exiting purified gas, an irrigation device, a swirler, a straightener for straightening the flow and a sludge collector.

The disadvantage of the prototype is the relatively low efficiency of the dust collection process.

The technical result is an increase in the efficiency and reliability of the dust collection process.

This is achieved by the fact that in a centrifugal gas scrubber containing a housing, a pipe for introducing dusty gas, a pipe for exiting purified gas, an irrigation device, a swirler, a straightener for equalizing the flow and a sludge collector, the irrigation device is made in the form of a cylindrical, cylindrical, closed on one side, cylindrical a chamber having a tangential longitudinal groove for fluid exit, and a drop eliminator is installed after the spinner, and the direction of twist of the gas flow from the swirl is opposite to the direction iju twist spray liquid from the spray device.

The drawing shows a General view of a centrifugal gas scrubber.

A centrifugal gas scrubber comprises a housing 1, a nozzle 3 for introducing dusty gas, a nozzle 2 for exiting the purified gas, an irrigation device 8, a swirler 4, a straightener 5 for equalizing the flow, and a sludge collector 10 with a settling tank 11. The irrigation device 8 is made in the form of a hollow closed with on the one hand, a cylindrical chamber 8 having a tangential longitudinal groove 9 for exiting the irrigation fluid, and after the spinning device 5, a drop eliminator 6 is installed, and the direction of twisting of the gas flow from the swirl 4 is opposite twist direction of liquid spray from the spray device 8.

Gas centrifugal action is as follows.

The dusty gas stream enters the housing 1 through the inlet 3 of the dusty gas stream and encounters a swirl 4 in its path, where the gas stream swirls. When leaving the swirl 4, the gas stream meets a swirling atomized liquid stream having a twist direction opposite to that of the gas stream. As a result of this interaction, a gas-liquid suspension is formed, which enters through the spinning device 5 into the separator-droplet separator 6 of the liquid phase, and then through the pipe 2 is released into the atmosphere. Sludge is discharged through a sludge collector 10 into a sump 11.

The proposed apparatus can be used to clean fine dust and humidify air in ventilation units and air conditioning units, as well as in trapping mists, readily soluble dust, as well as in joint processes of dust collection, gas cooling and absorption. The effectiveness of the proposed design of the apparatus increases due to the larger surface of gas-liquid suspension by using counter-swirling flows of liquid and gas and in the above processes and when collecting dust particles larger than 5 microns in size is about 95 ... 97%.
