Dust collector

one

The invention relates to the field of filtration, namely, devices for cleaning gas from dust and can be used in various sectors of the national economy, mainly for trapping non-wetted dust.

A ventilating air cleaning apparatus is known, consisting of a lower chamber, with a tangential nozzle for introducing the gas to be cleaned, for the gas and for the upper chamber in which the box is installed.

A disadvantage of the known apparatus is the low efficiency of the cleaning process, aaaa, the absence of a tank-settler connected by a nozzle to the upper chamber, hence the water contaminated with dust particles from the upper chamber is discharged to the lower one, which contributes to the accumulation of sludge on the water surface in the lower chamber in case of non-wettable trapping dust. A dust collector is also known, comprising a housing divided into two chambers, a lower and an upper one, a tangential nozzle for introducing the gas to be purified into the lower chamber, equipped with with capacity

for fatness, the axial tube of the liquid flows into the upper chamber, in which a filter was installed, a branch pipe for discharging polluted fluid with u / l) dust, and a branch pipe for inlet of the cleaned gas 2 JDust collector is closest to the invention by its technical essence and the achieved result.

In this apparatus for trapping non-wettable dust, it is necessary to add wetting agents in that it does not contain a settling tank with an upper branch pipe for sludge discharge and does not have a spun vortex installed against the axial tube in the lower chamber. This leads to the accumulation of dust on the surface of the water in the tank. Non-wettable dust, clogging of the internal elements in the dust collector and

the deterioration of air purification efficiency, and the use of wetting agents that contribute to the settling of sludge in water, is associated with additional economic costs.

The aim of the invention is to increase

Efficiency of operation in trapping non-wetted dust without the use of a wetting agent.

This is achieved by the fact that, in a known dust collector having a body divided by a partition into two chambers, the bottom: and the top, tangential pipe of the altitude of the gas being cleaned into the bottom chamber, equipped with a liquid container, is the axial tube of the liquid-gas flow duct into the upper chamber, in which a drop catcher, a pipe for discharging the separated liquid with trapped dust and a pipe for discharging the cleaned gas are installed, a tank-sump with an upper pipe and a slurry discharge is installed, connected to the pipe of the oTBOiia tank; caught dust from the upper chamber.

It is advisable for the chamber against the axial tube to stabilize the blade swirl.

FIG. 1 depicts a pre-dust collector obtsitsy vits; in fig. 2 is a section along A-A in FIG. 1; on 4 mg. 3 ... a section along BB in FIG. one.

The dust collector consists of a qi / schnaric case 1 with a tangschy nozzle 2 for introducing the gas to be purified into the lower chamber 3, a tank 4 connected to the 1st chamber, a swirler 5 installed by a tank 4, a tube 6 attached to the tank 4, valves 7 and 8, the upper nozzle 9, the bump stop 10, the nozzle 9 is attached to the tank-sump 11, the outlet nozzle 12 attached to the lower part of the upper chamber 13, the axial tube 14, the drip catcher 15, the size of the one in the upper chamber and the tangential nozzle 16 for i. biBOtui purified gas.

Kopiivc 1 can spike from any cross-section of any profile, mainly cyl) P1ap1; The swirler 5 consists of the blade elements of the trapeenoidal profile and is attached directly to the upper edge of exhgosti 4 around its perimeter with: oche1 and against the axial tube 14, and the capacity of the container is mainly conical. Won ill 7 serves to clean the apparatus and hold a certain level, and vent 8 just to periodically rinse the existential sump. For the purpose of gaieni of speed- and changing the direction of movement of the water flowing through the nozzle 12 with catching dust, a 1O chipper, installed in a vice plate attached to a CTeHKG clarifier tank, is installed.

The sump is made with a cylindrical and rectangular section, and an additional float valve can be placed in it.

The purpose of the drop catcher 15, consisting of individual plates, is to catch water droplets and dust particles and divert the formed slime into the lower part of the upper chamber 13 by sweeping over the plates.

Dust collector works as follows.

The dusty air that enters through the nozzle 2 twists on the national surface of the air in the tank 4 in such a way that the water itself and the tank itself are twisted, which the Swirl 5 contributes to, resulting in a water-air mixture in the central tube 14, where OC proceeds: -: C- LJ. To flush the air, 1-1a exit from the pipe 14, the sub-air mixture goes through the chimney 15, where under the action of centrifugal forces e4x takes place)) efficient separation of droplets with dust particles from the air stream, and vented air is removed

from the apparatus along the tangtschialny pipe 16. The otaelekna water with trapped dust is poured over the plates of the droplet separator 15 into the lower part of the upper chamber 13 and the stalk over the

patrzyuku 12 - into the tank-sludge tank1k 11. In the tank-sump part. non-wet dust in the vice foam rises to noBtjpxHo water, which is facilitated by the breaking off 10, changing the direction of the stack speed of the contaminated warmer through the nozzle 12, and then merging along the upper nozzle 9 into the fuel; - blunt into the tank 4, which ensures the internal circulation of water in the apparatus.

Mode of operation P1) Gleulovitel depends on

the amount of treated air, em-o) hachalnogo dust, shziko-chemical properties of dust and water level. The concentration of a certain level of water (x; l

Despite the fact that the circulation of water is stopped in the apparatus, the control} {and the dust does not fall into the tank 4, due to the presence of -) the tank-sump and the llama apparatus is excluded, and when the blade is swirling installed in

The inner chamber is opposed to the axial shaft, intensive twisting, mixing of the gas with the liquid, and ee} x | s (fiction dust removal;

The apparatus may be in% gene to trap any wettable ibum. In this case, the slots from the tank-settler otsal sot through the valve 8.

Laboratory and production tests have shown the reliability of the work and the possibility of catching nonwettable dust.
