Description
Technical field
The utility model belongs to technical field of environment protection equipment, specifically, particularly relates to a kind of Venturi pipe water dust scrubber.
Background technology
Venturi water-curtain separate has been widely used on the smoke evacuation flue dust of boiler as a kind of high-efficiency dust remover equipment.The air-flow acceleration and pressure decrease when the ash-laden gas that boiler is discharged enters venturi collapsible tube, and impact the liquid of throat's water injector ejection, make it atomization.Small dust in flue gas is soaked by water smoke and mutually bonds, and is gathered into the bulky grain being easy to trap.Grit enters drop catcher, and produce by inlet volute and rotate, under the influence of centrifugal force, soot particle is separated with flue gas and is got rid of on cylinder inwall, is poured in pollution discharge pond by the top-down moisture film that overflow launder is formed, and clean flue gas rises and is discharged into boiler induced-draft fan place.
The water of overflow launder is from top to down without any impact mitigation measure, and its structure, as shown in Figure of description Fig. 1, is easy to make top-down moisture film in cylindrical shell, form the barrier of one water, accounts for the cambered surface width corresponding to cylindrical shell 110 ° of central angles.The moisture film fallen is entrainmented rising by the flue gas rotated.Take drop catcher out of, add flue gas water content.Slow down because flue gas is blocked by entrance moisture film, cause flue gas to decline at cylindrical shell rotational flow intensity inside, decrease centrifugal action, dust separation efficiency is declined, have impact on dust removing effects.
Summary of the invention
The utility model discloses a kind of Venturi pipe water dust scrubber, easily form water barrier for the overflow launder solving traditional venturi water-curtain separate, have a strong impact on the problem of dust separation efficiency.
The utility model is achieved through the following technical solutions:
A kind of Venturi pipe water dust scrubber, comprise Venturi tube and drop catcher, described Venturi tube comprises collapsible tube, trunnion and extension tube, described trunnion is provided with throat's water injector, described throat water injector is connected with the water pump in pond by water pipe first, and be connected with pollution discharge pond by blow-off pipe bottom described drop catcher, described drop catcher is provided with buffering overflow launder, described buffering overflow launder is provided with at least one buffering slope, and described buffering overflow launder is connected with water pump by water pipe second.
The size of the described inclined-plane on buffering slope and the included angle A of horizontal plane is 10 °-45 °.
The groove depth size H size of described overflow launder is 60-100cm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is skillfully constructed, simple for structure, realizes cost low, and solve the interior problem easily forming moisture film of drop catcher of traditional deduster, increased substantially dust separation efficiency, efficiency of dust collection is significantly improved.The utility model has very high practical value, can be widely used in technical field of environment protection equipment.
Accompanying drawing explanation
Fig. 1 is traditional deduster drop catcher longitudinal sectional drawing;
Fig. 2 is the utility model structural representation;
Fig. 3 is the longitudinal sectional drawing of the utility model drop catcher.
In figure: 1. Venturi tube; 2. drop catcher; 3. collapsible tube; 4. trunnion; 5. extension tube; 6. water pipe first; 7. pond; 8. water pump; 9. blow-off pipe; 10. pollution discharge pond; 11. buffering overflow launders; 12. buffering slopes; 13. water pipe second.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of Venturi pipe water dust scrubber, comprise Venturi tube 1 and drop catcher 2, described Venturi tube 1 comprises collapsible tube 3, trunnion 4 and extension tube 5, described trunnion 4 is provided with throat's water injector, described throat water injector is connected with the water pump 8 in pond 7 by water pipe first 6, be connected with pollution discharge pond 10 by blow-off pipe 9 bottom described drop catcher 2, described drop catcher 2 is provided with buffering overflow launder 11, described buffering overflow launder 11 is provided with at least one buffering slope 12, and described buffering overflow launder 11 is connected with water pump 8 by water pipe second 13.
The size of the described inclined-plane on buffering slope 12 and the included angle A of horizontal plane is 10 °-45 °.
The groove depth size H size of described overflow launder 11 is 60-100cm.
The utility model buffering overflow launder 11 is provided with two buffering slopes 12, and the size of the described inclined-plane on buffering slope 12 and the included angle A of horizontal plane is 25 °, and the groove depth size H size of overflow launder 11 is 75cm.
Buffering overflow launder 11 is connected with water pump 8 by water pipe second 13, by in water suction buffering overflow launder 11, two buffering slopes 12 through cushioning overflow launder 11 slowly flow in drop catcher 2, form top-down moisture film, water barrier can not be formed, guarantee that flue gas should have flow velocity, make to form good eddy flow field in drop catcher 2, ensure the efficiency of dust collection of equipment.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
