The invention relates to techniques for wet dust collection and can be applied in chemical, textile, food, textile and other industries for cleaning dust-Laden gases.

The closest technical solution to the declared object is gazopromyvateli, known from the book Sew. Handbook of dust and sololarini. M.: Energoatomizdat, - 1983, str, RES (prototype), comprising a housing with inlet and outlet nozzles, a tank of liquid and with a level regulator, the impeller consisting of inclined blades with partitions and concave plate, a device for removing sludge.

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

The technical result - improving the efficiency and reliability of process dust collection.

This is achieved by the fact that in hydrodynamic dust collector, comprising a housing with inlet and outlet nozzles, a tank of liquid and with a level regulator, vasomedical consisting of inclined blades with dividers and two layers of a pair of concave plates, symmetrical with respect to the axis of the apparatus, and one of the Central plate, and a device for removing sludge in the upper layers of the liquid placed a vibrator fixed to the housing via an elastic perforated membrane, p is item the ratio of the width "a" of inclined blades to the width "b" of the first pair of concave plates is in the optimal range of values: a/b=...4,5 4,0; and the ratio of the width "b" of the first pair of concave plates to the width "C" of the second pair of concave plates is in the optimal range of values: b/C=1,25...1,5, and the vibrator is made in the form of a cross-section inscribed in the dimensions of the tank with liquid.

The drawing shows a General view of hydrodynamic paleudults.

Hydrodynamic dust collector includes a housing 1 with an inlet 10 and 11 and outlet 12 in pipe, tank 2 with the fluid and with level control 8 liquids, vasomedical 4, consisting of inclined blades 3 with partitions and two layers of a pair of concave plates 7, symmetrical with respect to the axis of the apparatus, and one of the Central plate 6, and a drip pan 5 and the device for removing sludge 9. In the upper layers of the liquid placed the vibrator 13, fixed to the housing via an elastic perforated membrane 14, and the ratio of the width "a" of inclined blades 3 to the width "b" of the first pair of concave plates 7, is in the optimal range of values: a/b=...4,5 4,0; and the ratio of the width "b" of the first pair of concave plates 7 to the width "C" of the second pair of concave plates 7 is in the optimal range of values: b/C=...1,5 1,25. The vibrator 13 is in the form of a cross-section inscribed in the size of the tank 2 with the liquid.

Hydrodynamic dust collector works as follows.

Dust-Laden gas stream enters the housing 1 through Pat the skirts 10 and 11 and carries the fluid in the channel (impeller) between the inclined blades 3. Part drops from the resulting gas-liquid mixture is pressed air to the concave part of the plate 7 and then discarded on a partition, the rest is fond of air through the gaps between the plates in the upper part of the body where it is finally rejected by the plate 6. The cleaned gases passing through the eliminator 5, are released into the atmosphere, and the water together with the caught dust flows into sumopaint 9. The required level of liquid in the apparatus is supported by the controller 8. In the upper layers of the liquid placed the vibrator 13, fixed to the housing 1 by means of perforated elastic membrane 14, which increases the surface interaction of gas and liquid mist dust creation librarypage layer in the upper layers of the liquid, which leads to a more intensive mixing of the gas streams and liquid.

The proposed apparatus can be used for removal of fine dust and air humidification in air handling units and air conditioning installations, as well as capture fogs, soluble dust, and for co-processes in dust control, cooling gases and their absorption. The effectiveness of the proposed design of the apparatus increases due to the larger surface of the gas-liquid suspension, by applying vibropiling layer in the liquid and the status is made in the above processes and the capture of dust particles larger than 5 microns approximately 92%to 95%.
