Description

Sh. I. GAZOOCHI February 1W8 at K Charged 27 at the Council of Ministries Published 3 Gas cleaners are known, based on the use of sharp turns of individual jets of a gas stream during its passage through the gaps of gas cleaning elements. Gas scrubbers, combining, and the principles of inertia and cyclone gas cleaning are also known. The gas scrubber according to the invention is characterized by a special arrangement of slots in the gas scrubber elements; in the presence of several concentrically arranged elements and with a relatively small expenditure of energy, it is able to give a high degree of gas purification. FIG. 1 and 2 show the proposed gas scrubber in section and in plan; in fig. 3 and 4 schematically show the location and operation of the slots. The gas cleaner (FIGS. 1 and 2) consists of gas cleaning elements L 2 and 5, smooth hollow cylinders 4, 5 and 6, bottoms 7 and (§, mesh 9, inlet 10, outlet 11, casing 12, inside the cylinder 13, roof 14 and the filtering layer 15. The gas cleaning elements (Fig. 3) consist of strips 16, 17 and / S, fastened together among the tenants, so that along their entire length there are insker TITLE m and tr-f "pbt" Mi3MA5 | USSR number 37484) | Pltp / 11; o .. ,, Nvar 1950 TEKHA; 1; EG / D5; PK i; fOTvr, slots 19, 20 and 21 are formed. In this way, the width of the slit 19 along the entire length of the gas cleaning element is about 1.5. / MyVj, the width of the slits 20 and 21 is about 0.5 mm, and the total area of the slit section of each of the elements are larger than the cross-sectional area of the outlet pipe. The gas cleaning element is made of a single sheet, in which the cuts are preliminarily made and the sheet bends at the cuts, so that cracks of the specified width are formed. These slots are located in the apparatus along the forming cylindrical surface of the gas cleaning elements. The operation of the scrubber proceeds as follows. The gas to be purified (Fig. 1) is introduced into the cylinder 13 through the nozzle 10 tangentially to the cylinder forming. The matter of inertia is a few turns, it is subjected under the action of centrifugal force to the initial rough cleaning. Then, changing direction, the gas enters the gap 19 (Fig. 3). Due to the sudden rotation of the gas jet and the pressure drop over the blade forming the slit (Fig. 4), some of the microscopic dust particles are pulled out of the thickness of K by the inertia of the gas jet going into slit 19, and, whirling, come into contact with other dust particles. Dropped by centrifugal force to the generator of the mote cylinder, compacted, fall into the bunker.

Passing in the same way through the slots of the following gas cleaning elements, the gas is cleared more.

The grid 9 and the filter layer 15 serve to clean the gas pro-layer between the elements 2 - 3.

In order to compact the dust between elements 1 and 2, an injection-type device can be applied, by means of which a part of the gas to be purified passes through the slots of the element again.

The thickness of the middle layer of the gas flow in the apparatus is approximately equal to the width of the slit. The distance between the slits is determined experimentally, and the number of gas-cleaning elements is determined by the specified gas cleaning rate.
