    1442417 Gas filter GEORG FISCHER AG 7 Dec 1973 [7 Dec 1972] 56965/73 Heading BIT A gas filter comprises at least one inwardflow filter tube or pooket 2 attached to a filter gas outlet 6 above which is arranged a reverse flow gas delivery nozzle (5) Fig. I, (not shown), outlet 6 comprising concentric tubes 7, 8, the inner tube being non-uniform in axial section and having one or more holes or slots 14 in its wall between its open ends 12, 13. Tube 7 is removably supported in tube 8 by radial straps 15, which may be twisted to impart rotation to gas flowing along space 10. Tubes 7, 8 correspond in transverse sectional shape to the filter tube/pocket 2 (Figs. 3 to 6, not shown). Tube 7 shown has a double frustoconical form, but could be double frustopyramidal or have other axial sections (Figs. 7, 8, not shown). Outlets 6 are fixedly or removably mounted to extend through a wall 18 separating filtered and dirty gas chambers, and a filtered gas outlet fan (23) and reverse flow valves (4) are included. Filter tubes/pockets 2 are demountably clamped round tubes 8. The outlet construction is stated to improve reverse flow cleaning efficiency without being of excessive height.

    (5 i) GAS CLEANER
    one
    The invention relates to the purification of gases from dust and can be applied in the chemical industry.
    A gas scrubber is known, including a j-cadium casing with inlet and discharge ducts, inside of which are bag filters with inlet nozzles, which are fitted coaxially with nozzles and pas: washing gas fl.
    However, this gas scrubber has significant dimensions and low cleaning efficiency.
    The purpose of the invention is to increase the cleaning efficiency and reduce the size of the device.
    The goal is achieved by the fact that the flushing gas nozzles are located from the outlet nozzle of the sleeve 20 and the smallest effective cross section of the nozzle of the upper part is larger (or equal) to the nozzle section in the lower part and the upper section of the nozzle facing the flushing gas nozzle a is narrowed, and the lower part is made with holes.
    In addition, the length of the nozzle should be equal to the length of the nozzle sleeve.
    It is preferable to form the nozzle and the outlet nozzle of a circular elliptical section.
    It is also preferable to form the nozzle and outlet nozzles of square or rectangular cross section.
    In addition, it is necessary to perform the shape of a sopra-shaped, drop-shaped, in the form of truncated cones or in the form of two truncated pyramids.
    It is preferable to provide the nozzle and the outlet nozzle ribs located on the gas flow.
    Figure 1 shows the scrubber, vertical section; in fig. 2, node 1 in FIG. one; figure 3-6 - section aa in figure 2, - options.

    Claims (5)
    [1]
    The gas cleaner includes a housing 1, a separation wall 2, which separates it into the chamber 3 of a clean chamber 4 of dusty gas, a pipe 5 for supplying dusty gas and a pipe 6 for supplying dusty gas, a dust bin 7 for dust and a pipe for dust removal pure gas suction Yaatrubok 10 for removal of pure gas, purge nozzles 11, devices for supplying purge gas 12, with control of the device 13, filter elements 14, with outlet nozzles 15, output nozzle includes a nozzle housing 16, coaxially installed the nozzle 17, on the ribs 18, in the lower part of the nozzle 17 are the holes 19. The scrubber works as follows. The dust-laden gas through the pipe 5 enters the housing 1 and is filtered through the filter elements 14 and is discharged through the pipe of a pure gas 10. The regeneration of the filter element takes place by supplying compressed gas to the purge nozzles 11, then it enters the husk 17 and the nozzle 15 into the internal cavity, by creating a shock wave in the nozzle 17 and twisting the gas flow between the ribs 1, the filter element is cleaned. Claims 1. Gas scrubber, including a tank with inlet and exhaust ducts, inside of which are bag filters with outlet nozzles, which are coaxially fitted with gas nozzles and nozzles npONttJB04Horo, which
    one}
