Description

The invention relates to techniques for wet dust collection and can be used in chemical, textile, food, light and other industries for the purification of dusty gases.

The closest technical solution to the claimed facility is gas scrubbing, known from the book by A. A. Rusanov. A guide to dust and ash collection. M .: Energoatomizdat, - 1983, p. 103, Fig. 4.21 (prototype), comprising a housing consisting of upper and lower sections, a pipe for introducing dusty gas, a pipe for exiting purified gas, a spray catcher with a centrifugal swirler and a pipe for liquid drainage from the spray trap, irrigation device, plates with a stabilizer, nozzle for periodic irrigation of the swirler and sludge collector.

The disadvantage of the prototype is the relatively low efficiency of the dust collection process.

The technical result is an increase in the efficiency and reliability of the dust collection process.

This is achieved by the fact that in a gas scrubber containing a housing consisting of upper and lower sections, a nozzle for introducing dusty gas, a nozzle for escaping purified gas, a spray catcher with a centrifugal swirler and a nozzle for draining liquid from the spray catcher, an irrigation device, plates with a stabilizer, a nozzle for periodic irrigation of the swirler and sludge collector, at least on one plate, an additional vibrator is installed, and the vibrator is made in the form of the peripheral part of the plates and is fixed directly It is only on the plates or the vibrator is made in the form of the central part of the plates and mounted directly on the plates, and the vibrator is mounted directly on the body in the place where the plates are located and made in the shape of a toroid. The stabilizer cells are made square, and the ratio of the stabilizer height h c to the cell width b c is in the optimal range of values: h c / b c = 1.5 ... 1.8, and the plates are made hole-shaped with the ratio of the plate thickness h t to the diameter holes d o in the optimal range of values: h t / d 0 = 0.5 ... 1.5 or plates are made with holes with the ratio of the plate thickness h t to the width of the slots b o in the optimal range of values: b t / b o =, 08 ... 1.5, and the ratio of the height of the housing H to the diameter D is in the optimal range of values: N / D = 4.0 ... 6.5, moreover, the ratio of the housing diameter D to the diameter of the splash trap D 1 is in the optimal range of values: D / D 1 = 1.2 ... 1.25, and the ratio of the diameter of the housing D to the diameters of the inlet and outlet nozzles D 2 is in the optimal range of values : D / D 2 = 2.0 ... 2.5,

The drawing shows a General view of the gas scrubber.

The gas scrubber contains a housing consisting of upper 4, middle 5 and lower 7 sections, a nozzle 12 for introducing dusty gas, a nozzle 13 for exiting the purified gas, a spray catcher 1 with a centrifugal swirler 2 and a pipe 3 for draining liquid from the spray catcher, an irrigation device 9, plates 8 with a stabilizer 6, a nozzle 10 for periodic irrigation of the swirler and a sludge collector 14, moreover, at least on one of the plates 8, an additional vibrator 11 is installed. The vibrator 11 can be made in the form of the peripheral part of the plates (to hell hedgehog is not shown) and mounted directly on the plates or in the form of the central part of the plates 8 (not shown in the drawing) and mounted directly on the plates. In addition, the vibrator 11 can be mounted directly on the housing in the place where the plates 8 are located and made in the form of a toroidal. The cells of the stabilizer 6 can be made square, and the ratio of the height of the stabilizer hc to the width of the cell bc is in the optimal range of values: h c / b c = 1.5 ... 1.8. Plates 8 can be perforated with a ratio of the plate thickness h t to the diameter of the holes d o , which is in the optimal range of values: h t / d o = 0.5 ... 1.5. Plates 8 can be made slotted with the ratio of the plate thickness h t to the width of the slots b o , which is in the optimal range of values: h t / b o = 0.8 ... 1.5. The ratio of the housing height H to the diameter D is in the optimal range of values: N / D = 4.0 ... 6.5. The ratio of the diameter of the housing D to the diameter of the splash trap D 1 is in the optimal range of values: D / D 1 = 1.2 ... 1.25. The ratio of the diameter of the housing D to the diameters of the inlet and outlet nozzles D 2 is in the optimal range of values: D / D 2 = 2.0 ... 2.5.

The gas washer works as follows.

The dusty gas stream enters the housing through the inlet of the dusty gas stream 12 and meets plate 8 on its way, then the gases pass through the liquid layer in the form of bubbles (foam), on the surface of which dust particles are deposited. The device operates in the mode of a wet dust collector with a failure plate, which reduces the likelihood of clogging of the openings of the plate 8 with dust, since the supply of gases to and from the zone of contact with the liquid is carried out through the same hole or slotted openings of the plates 8. The formation of gas-liquid suspension (foam ) is further enhanced by the creation of a vibro-boiling layer in the upper layers of the liquid located on the plates 8, due to the use of a vibrator 11, which leads to a more intense interaction of gas and liquid flows. Then the exit of gas-liquid suspension through the liquid phase separator, made in the form of a spray catcher 1 with a centrifugal swirler 2 and a pipe 3 for draining the liquid from the spray catcher. Sludge is discharged through sludge collector 14.

The proposed apparatus can be used to clean fine dust and humidify air in ventilation units and air conditioning units, as well as in trapping mists, readily soluble dust, as well as in joint processes of dust collection, gas cooling and absorption. The effectiveness of the proposed design of the apparatus increases due to the larger surface of the gas-liquid suspension, by using a vibro-fluidized bed in a liquid and in the above processes and when collecting dust particles larger than 5 microns in size is about 92 ... 95%.
