Abstract

The utility model relates to a complex eddying wet-type high efficiency dust remover, which comprises an inlet smoke pipe, an eddy gas-liquid mixer, a water chamber and a smoke exhausting pipe. The complex eddying wet-type high efficiency dust remover has the dust removing effects of spraying dust removing and inertia dust removing, in particular to a various integral dust removing effect of the high three-sensor dust removing generated in a two-phase interface. The complex eddying wet-type high efficiency dust remover has the advantages of high dust removing efficiency, simple structure, compact structure, low cost and easy installation and maintenance. The utility model can be widely used for gas purifying in industrial furnaces of smelting, electric forces, chemical industries, building materials, ceramics, food, textiles, etc.

Description

Complex eddying wet-type high efficency dust remover

The utility model is a kind of smoke eliminator--the deduster that belongs in the Industrial Stoves.

Normally used deduster has electric cleaner, sack cleaner on the Industrial Stoves at present,

Though both efficiency of dust collections are up to more than 95%, but the former invests greatly, power consumption, and the latter, cloth bag is fragile, safeguard very trouble, even influence production, and cyclone dust collectors, though inertial dust separator is simple in structure, invest lessly, but its efficiency of dust collection is lower, is difficult to satisfy environmental requirement strictly speaking.As impingement dust collector.It is by smoke-intake pipe, pipe, and hydroecium constitutes, and structure is very simple, but its efficiency of dust collection can only reach about 60～80% generally speaking.

The purpose of this utility model is to provide a kind of simple in structure, and cost is low, and is easy to maintenance, the compound type dust remover that efficiency of dust collection is high.

The purpose of this utility model is achieved like this: on the basis of impact type deduster, set up one section spray, centrifugal dust-removing, make it to become a kind of deduster of combined type.

The utility model is made up of smoke-intake pipe, pipe, hydroecium, in hydroecium and with smoke-intake pipe, connect and load onto one by shell, spiral leaf, whirlpool core, spray thrower, the vortex gas-liquid blender that water inlet pipe constitutes, in the hydroecium hydrocone type drainpipe is housed simultaneously, so that the water surface in the hydroecium remains certain altitude, the operate as normal of simultaneously continuous venting buck maintenance deduster.

Spray thrower in the above-mentioned vortex air and liquid mixer is made by conical pipe, to reduce flue gas resistance, be densely covered with the water hole of the atomizing globule on the tube wall of conical pipe, make water smoke can sweep away the cross section of whole air-flow, the dust in the flue gas can be able to the most effective adhesion, capture by water smoke.

Spiral leaf in the above-mentioned vortex air and liquid mixer has two helical pitches at least, its not the limb of the spiral leaf of a helical pitch of tail and the inwall of shell have certain clearance, limb of the spiral leaf of helical pitch is that driving fit contacts with the inwall of shell on it.

Dust removal process of the present utility model and principle are summarized as follows:

Flue gas enters the vortex air and liquid mixer from smoke-intake pipe, at first pass through the water spray territory of spray thrower, make the dust in the flue gas be adhered to, capture by water smoke, enter the helical duct that the spiral leaf constitutes then, do the motion downwards of garden week, because action of centrifugal force, the water droplet of dust-laden is thrown to inner wall of tube shell, when arriving the spiral tail again because the acting in conjunction of gravity and the downward thrust of flue gas makes the dust-laden water droplet fall into the water of hydroecium along tube wall.

The flue gas that is cleaned twice continues to rotate rapidly the liquid level that flings in the hydroecium downwards, liquid level is subjected to intense impact, the friction of high speed swirling eddy, under air-flow, formed the concavo-convex liquid level of a rotation, thereby enlarged the contact-making surface of gas-liquid two-phase, strengthened the exchange of quality, heat, momentum between the gas-liquid.Between this, the part dust that is left in the flue gas, solable matter constantly move into liquid phase from gas phase, thereby flue gas is further purified, and tangentially are thrown into smoke exhaust pipe along space on the hydroecium through deflector at last through three degree flue gas after being purified and discharge.

Dust-laden sewage in the above-mentioned hydroecium most of is discharged by siphon drainage pipe, other then wash when cleaning hydroecium.

This shows, in the utility model, adopted spraying and dedusting, centrifugal dust-removing, inertial dust collection and two-phase interface three to pass the composite dedusting mode of purification process, dust removing effects is greatly improved, simultaneously of the present utility model simple in structure, easy to maintenance, its manufacturing cost also is lower.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model.

Embodiment: referring to Fig. 1, Fig. 2, fill the water 9 of 2/5 height in the hydroecium 7, corresponding therewith being equipped with keeps the constant hydrocone type drainpipe 10 of water surface elevation, and compression device 8 is housed in the porch of drainpipe 10, so that discharge buck, the last space of hydroecium 7 has tangential exhanst gas outlet 13, and deflector 14 is housed, with the tangential exhanst gas outlet 13 vertical smoke exhaust pipes 15 that are equipped with.

By shell 4, spiral leaf 5, whirlpool core 6, spray thrower 3, the eddy airstream blender that water inlet pipe 2 is formed is contained in the hydroecium 7, and the upper end is connected with  is smooth simultaneously, and the water surface 9 in lower end and the hydroecium 7 is at a distance of certain altitude.Spray thrower 3 wherein is that a conical pipe is made, have densely covered aperture on the tube wall, make water fogging, spiral leaf 5 wherein has two helical pitches around whirlpool core 6, and both are fixedly connected, the spiral leaf 5 of first helical pitch contacts with shell 4 driving fits, the spiral leaf 5 of following helical pitch and the gapped ε of inwall=10 of shell 4.

For the ease of cleaning, in hydroecium 7, divide lower device that clear water pipe 12 and blow-off pipe 11 are arranged.

The flue gas ash removal process is summarized as follows:

Flue gas enters the vortex air and liquid mixer from smoke-intake pipe 1, at first the water smoke through spray thrower 3 carries out spraying and dedusting, enter the helical duct that constitutes by spiral leaf 5 again and carry out centrifugal dedusting, carry out the inertial dust collection that two-phase three passes once again through flue gas after being purified twice and then with the water surface in the hydroecium 7 then, by the last space of hydroecium 7, throw to smoke exhaust pipe 15 from tangential exhanst gas outlet 13 and discharge at last.

Experiment shows, the utlity model has the efficiency of dust collection more than 96%.
