Abstract

A dust-moisture separator for removal of dust and moisture from output gases from isolated from environment apparatuses contains a housing, a hollow cylinder with window openings, screens, a swirl vane, a separator, a drop deflector, scrapers, a flue, sealing elements. The use of this dust-moisture separator allows to return the collected waste products back to the technological apparatus, and not into the additional tank.

Description

Description of the invention

The invention relates to devices for cleaning exhaust gases from dust and moisture from devices isolated from the environment and allows returning captured products to the technological device and can be used in the chemical and food industries.

A known wet dust collector (1), which contains a body with gas inlet and outlet nozzles, gas ducts with guiding vanes and deflectors, sprinklers, drip deflectors, each of which is made in the form of paired corners, a device for unloading sludge, made in the form of a conical valve and a hydraulic valve, 70 which is made in the form of a siphon.

The disadvantage of the known invention is the low efficiency of gas purification, because when water flows down the surface of the drip deflector to the walls of the case, part of the water is carried away by the gas into the atmosphere, contaminating it. When unloading sludge through the unloader, which is made in the form of a conical valve, continuous discharge of sludge is not ensured, because it is carried out periodically, which leads to the accumulation of 12 sludge deposits that clog the outlet pipe, and this reduces the efficiency of the dust collector, as well as the design of the hydraulic valve, made in the form of a siphon; which does not ensure uninterrupted flow of the treated liquid if there is a large amount of solid particles in it.

The closest in terms of technical essence is the wet dust and gas trap (2) chosen as a prototype, which contains a body, a gas supply nozzle, a gas outlet nozzle, drip deflectors made in the form of paired corners with longitudinal holes. Drip deflectors are located above gutters with nozzles.

In the lower part of the case, drain pockets and a scraper unloader are installed, which are connected by a pipeline to a hydraulic valve, which contains an external cylindrical-conical chamber, the unloading part of which has a cut.

The disadvantage of the known invention is that the design of the dust-water separator requires auxiliary equipment (a container for collecting captured products). in

The task is solved by the fact that in the dust separator, which contains a hollow cylinder, in which a second hollow cylinder of a smaller diameter is mounted, the swirler is a separator, which divides the body into two expansion chambers, as well as windows for the removal of captured products back to the technological apparatus, from where the gas is released. what

The new set of essential features is sufficient to achieve the task. Cha

Dust and moisture separator, which contains: - body 1, which is a hollow cylinder with a conical part at the bottom; o - a hollow cylinder 10 of a smaller diameter, which is mounted in the lower part of the housing 1; Ge) - window openings 11, which are made in the walls of the body 10 above the line when the conical part is connected to 325 of the cylinder 10; - - screens 6, which partially cover the window openings; - screen 5 with windows for draining condensate into the lower part of the housing 1 to prevent the gas being cleaned from directly entering the gas duct 9; « - swirler 2, which is made in the form of a cone with inclined blades and a spherical upper part for the drainage of trapped moisture and dust, the support of which is the cylinder 10; c - separator C is made in the form of a double cone, which expands downwards and narrows upward,

Iz" mounted on swirler 2, divides the housing of the dust and moisture separator into two expansion chambers, dust collection chamber A and moisture collection chamber B; - drop deflector 4, which is a system of conical umbrellas that form a labyrinth on the path of the outgoing gas, mounted inside the separator 3; - - gas duct 9, which is a continuation of the droplet deflector housing for discharging purified gas into the atmosphere or onto

Gee! further processing; - scrapers 7 for cleaning from dust; o - sealing unit 8 to prevent the release of gas being cleaned into the environment; -And 20 The dust and moisture separator works as follows:

The dust and moisture separator is installed on the device from which moist, dusty gases are removed. To ensure the working functions of the dust and water separator, it is necessary that the speed of gas entering the swirler is 15-20m/s, and the speed at the end of the expansion chamber is no more than 0.5-0.8m/s.

The gas enters the dust separator through the nozzle 10 and flows around the screens b, thus creating a vacuum 29 in the area of the windows 11. Next, the gas through the swirler 2 enters the expansion chamber A. After passing through the swirler 2, the gas acquires a rotational movement relative to the longitudinal axis, and thanks to this dust under the influence of inertial forces is thrown to the walls, where it settles. The gas that passes through the expansion chambers A and B expands and cools, thanks to which the moisture in the gas condenses and settles on the walls. Drops of moisture that have not settled on the walls are retained by the drip catcher. Captured dust and moisture flow under their own weight into chamber 60 for collecting dust and moisture B. The dust that has settled on the walls is removed with scrapers and also enters chamber B.

From chamber B through windows 11, moisture and dust flows back into the technological apparatus.

The proposed design of the dust and water separator allows you to return the collected waste products back to the technological apparatus, and not to an additional container.
