Abstract

The utility model provides a tubular shape blade wheel wet dust remover, which comprises an outer cylinder, an inner cylinder, an impeller cylinder, a smoke inlet cylinder and a water spraying pipe. The utility model is characterized in that all the cylinder (pipe) form concentric circles and are sheathed with each other from the external to the internal; the outer cylinder is provided with a smoke outlet; the lower part of the inner cylinder is provided with a water outlet; the lower part of the inner cylinder is communicated with the lower part of the outer cylinder through a branch leg of the inner cylinder; blade is arranged on the impeller cylinder, and a closure end-face at the upper part of the impeller cylinder is fixed with an impeller shaft; a belt pulley is arranged on the impeller shaft; the lower end of the impeller shaft corresponding to the place of the water spraying pipe mouth is provided with a water spraying cone.

Description

Tubular impeller wet scrubber

The utility model belongs to a kind of fume dust remover.

Flue gas ash removal is the main research topic of environmental protection.At present dust suppression one is to improve the stove and accessory combustion position, make fuel in the stove and accessory internal combustion fully reducing solia particle and harmful gas emission, the 2nd, deduster is set on discharge-channel.Deduster generally divides dry type and wet type two classes, typical wet scrubber such as venturi water film formula deduster are to form water membrane in flue, simultaneously with the flue diameter by dwindling the raising smoke density greatly, flue gas sprays into moisture film formation rotational flow at a high speed makes moisture film be stained with flue dust, good dedusting effect.But because flue gas and moisture film short collision opportunity time of contact are few, improve dust removing effects, must increase the deduster volume, so venturi water film deduster be up to tens meters.

The purpose of this utility model provides that a kind of volume is little, and water consumption is few, and good dedusting effect is applied widely, the novel fume dust remover that cost is low.

The technical solution of the utility model is: dust arrester is made up of urceolus, inner core, impeller tube, smoke-input tube and sparge pipe.Each (pipe) is concentric circles ecto-entad suit.Urceolus sets out mouth, and the inner core bottom sets out the mouth of a river, and blade is established in impeller tube inboard, and impeller shaft and belt pulley are housed on the upper closed end face, by its rotation of Motor Drive.A water spray cone is established over against water spray mouth of pipe place in impeller shaft the inner, makes water spray form lotus leaf shape moisture film in the impeller tube; Auxiliary water inlet pipe is established in inner/outer tube upper surface, impeller tube top.The inner/outer tube bottom communicates by the inner core supporting leg.Flue gas fully mixes inside and outside the impeller tube of rotation at a high speed with water, and the solid micronic dust is caught by water smoke and thrown away, and is discharged by discharge outlet, and clean gas is discharged from the urceolus exhaust opening.

Smoke abatement and dust control for the equipment of big exhaust smoke level can add fogger and Chu Yanqi before tubular impeller wet scrubber.Fogger is single-stage or the wet cigarette device of multistage tubular water spray, and flue gas is moistening in advance by moisture film, regulates evenly through storage cigarette device, can improve the deduster dust removing effects.

The utility model has the advantages that: the impeller of rotation makes flue gas fully mix with water smoke at a high speed, has improved the capturing ability of water smoke to smokeshade, the efficiency of dust collection height, and the deduster volume dwindles greatly; The scope of application is wide, and the deduster by design different volumes and different wheel speeds all can use to family's household stove kitchen range from Industrial Stoves; Save water and energy, this device is littler than venturi scrubber water consumption, but dust waste water repetitive cycling use after filtration.

Accompanying drawing 2 is secondary tubular water spray fogger orthogonal view.

Accompanying drawing 3 is storage cigarette device schematic diagram.

Embodiment is described in detail as follows in conjunction with the accompanying drawings:

Tubular impeller wet scrubber is made up of urceolus 1, inner core 2, impeller tube 3, smoke evacuation tube 4, sparge pipe 5, and each (pipe) becomes concentric circles ecto-entad suit.Set out mouth 6 on the urceolus 1, inner core 2 bottoms set out the mouth of a river 7, blade 8 is arranged on the impeller tube 3, its upper closed end face and impeller shaft 9 are fixing, belt pulley 10 is arranged on the impeller shaft 9, impeller tube 3 is driven by belt pulley 10 by motor, and water spray cone 11 is established in impeller shaft 9 lower ends over against the water jet place, make water spray form lotus leaf shape moisture film in impeller tube 3.Auxiliary water inlet pipe 12 is established in inner/outer tube upper surface, impeller tube 3 top, can reduce main jet water pipe injection flow rate and then alleviate impeller tube rotational resistance.The inner/outer tube bottom communicates by inner core 2 supporting legs 13.By the water smokes of discharging fume 4 flue gas of discharging and sparge pipe 5, assisting water inlet pipe 12 inside and outside impeller tube 3, to form, impeller tube 3 inside and outside fully mixing in rotation at a high speed, solia particle is caught by water smoke and is thrown away by impeller tube 3, is discharged by delivery port 7, and clean gas is discharged from the outlet flue 6 of urceolus 1.

Fogger can be used as the auxiliary equipment of deduster, can be used by single-stage or plural serial stage.At different levels by urceolus 21, inner core 22, smoke-input tube 23, sparge pipe 24 and moisture film sheet 25 are formed.Each (pipe) is the concentric circles suit from outside to inside.Outlet flue 26 is positioned at urceolus 21 tops, and delivery port 27 is positioned at urceolus 21 bottoms, and inner/outer tube communicates by inner core 22 lower leg 28, and moisture film sheet 25 is over against sparge pipe 24 spouts, and the two acting in conjunction forms moisture film.

Storage cigarette device advances mouth 32 by storage smoke-box 31, and outlet flue 33 constitutes, and its effect is to regulate the moving flue gas of equal constant current, improves the deduster dust removing effects.
