SU571287A1 - Hydrodynamic dust-gas trap - Google Patents

Description

one

The invention relates to devices for the purification of gases from dust and chemically harmful components and can be used in the chemical, rare-metal, metallurgical and other industries.

A hydrodynamic dust collector is known, consisting of a housing with nozzles for entering the dusty and clean gas outlet, a nozzle for removing sludge from the dust collector, a drip tray, a fluid level regulator in the apparatus, and a barbing unit made in the form of an annular nozzle formed by a shaped ring reinforced at the end of the nozzle for the entry of dusty gas, and with a bowl with a nozzle in the bottom, which is installed under the ring coaxially with it fl}.

A hydrodynamic dust and gas trap is known, which includes a housing with a bottom and a patent for thinning the fluid inlet and outlet, which is installed in the sprinkler and the inlet pipe equipped with a diffuser with a bubble-shaped partition 2 in the lower part.

A disadvantage of the known dust catchers is that the resulting dirt in the gaps accumulates on their lower part and clogs the lower nipple, to stop the dirt, it is necessary to stop the device.

In order to increase the degree of gas purification and eliminate sedimentation of solid precipitates in the proposed gas and gas trap, the distance from the bubble partition to the housing wall is 2-4 times the gap between the bottom and the troughs of the bubble partition wall equal to b, 05-О, 2 of the entrance diameter.

Moreover, the inlet pipe is installed with the ability to move vertically.

The drawing shows the proposed dust trap, longitudinal section.

Claims (2)

Dust collector includes a housing 1, made in the form of a cylindrical container having a bottom concave inside the bottom 2. The bottom 2 can be made flat. In the case 1 there are nozzles 3.4 for supplying and overflowing a liquid, in the bottom 2 of the apparatus there is a nozzle 5 for draining the liquid. In the housing 1 on the side of the riser viewing windows 6, in the upper part of the housing there is an inclined splash guard 7. The housing is closed by a cover 8 into which the branch pipe 9 is embedded, to which; attach the drip catcher 10. On top of the cover 8 there is. flange 11, and at the inlet pipe 12 in the upper part - flange 13. Flange 13 of the inlet pipe 12 through the gasket 14 is attached with a C-10 coupling compensator flange 15, and with its other flange through the gasket 14 to the flange 11 of the cover 8. The input pipe 12 is suspended by a flange 13 to the flaush 11 of the cover 8 on the bolts 16 and the nuts 17 is moved vertically. The entrance to the pipe 12 can be made a circle. The left, elliptic, quadrilateral and terminated at the bottom of the diffuser 18 with a bubbling partition 19 more gap formed between the bottom: 2 and the depressions of the teeth of the bubbling septum. When installing the inlet pipe iobho (A1M, it should be provided that the gap between the depths of the teeth of the bubbling partition and the depth of the apparatus is equal to 30-30 mm, which corresponds to O, 05-0.2 of the diameter or average cross-section of the entry pipe. The gap between the tooth cavities and the bottom of the apparatus is mm, as with an increase in this size, gases will not pass through the bottom of the apparatus, but higher, and thus solid particles will not settle down. The gap between the bubbling bulkhead and the body of the apparatus is 60–150 mm. increasing this size gas the solid particles will not fall against the wall and again, the dust catcher works as follows: After being assembled into the case, water or absorbing liquid is supplied through the pipe 3, which is poured to the level of the pipe 4. The liquid level in the device is installed in each individual case in different ways, therefore, there may be several nozzles 4. During operation, the gas is fed into the housing through the inlet pipe 12, then the gas through the diffuser 18 and the gaps between the teeth barbotage. The bulkhead 19 flows at high speed into the gas-liquid emulsion formed between the bubbling partition 19 and the wall of the housing. The purified gas rises upward through the emulsion, taking the drops of the liquid with it. The gas is then hit, on the sprinkler 7 where. the droplets are partially captured and flow down, and the gas further passes through the pipe 9 and the droplet separator 1O, where all the droplets are removed and flow as a liquid into the body, and the purified gas leaves the dust and gas trap. The absorption liquid, as it is saturated, together with the captured drink, is periodically or continuously drained through the overflow pipe 4, and the freshness through the pipe 3 is fresh. When leaving the dust collector through the drain pipe 5, all the water is drained off. The proposed sports center gives you the opportunity to increase the power of & gas cleaning due to better shotgun gas by the primary partition and $ 1 passer-by through emu. The elimination of settling of solid sediment is achieved by the fact that at the bottom of the gas the gas moves with great speed and thereby lifts all the solid particles that continuously move along with the absorbing liquid. Claim 1. Hydrodynamic dust trap, comprising a housing with a bottom and nozzles for inlet and outlet of a liquid, inside which is installed a drip tray and an inlet pipe, provided in the lower part with diffuse bubbling toothed partition, in order to increase the degree of gas cleaning and elimination sedimentation of solid precipitation, the distance from the bubbling partition to the hull wall 2-4 times disturbs the gap between the bottom and the trenches of the teeth of the bubbling partition, equal to 0.05-0.2 of the diameter of the inlet pipe. 2. The dust and gas catcher according to claim 1, wherein the input pipe is installed with the possibility of moving vertically. Sources of information taken into account in the examination: 1.
