Abstract

The utility model relates to a horizontal-type spiral washing and purifying dust cleaner, and the horizontal-type spiral washing and purifying dust cleaner belongs to environmental protection equipment. In order to solve the problems that the energy consumption is high and the efficiency is low in the prior dust cleaner, the utility model adopts a horizontal-type sprinkling, the water sprayed from each water spraying tube nozzle forms a water curtain in a spiral shaped fume channel, when the dust containing fume flows along the channel, the dust particles and SO <2> are captured by the water curtains of layer upon layer and the water film, and fall into a water tank, the excess water overflows to enter a water reservoir, and the water recycle is realized. Because the resistance force of the water curtain is small, under the synthetic action of a plurality of dust removal mechanism, the dust removal efficiency is high, and the energy consumption is low. The utility model is in particular suitable for the washing and purifying desulphurization and dust removal device used for the coal-burning boiler and the kiln stove. Compared with the similar equipment, the electricity can be saved by seventy percent by adopting the equipment.

Description

Horizontal spiral washing, purifying deduster

The utility model relates to a kind of environmental protection equipment, is particularly suitable for washing, purifying desulfation dust-extraction device---the horizontal spiral washing, purifying deduster that the smoke abatement and dust control of the kiln of township enterprise's refractory factory and coal-burning boiler is used.

The reason that vertical spray tower efficiency of dust collection is low, how close the ozzle that is no matter to spray water have, how many hole for water spraying is, in the same cross section of spray column, the gross area of hole for water spraying is compared always very little with the cross section of tower, that is to say that the water droplet under the spray is very little with the probability that almost is full of the whole cross section of tower, descend upstream ash-laden gas to collide certainly, so the grit of catching is few, and tower can not be done very highly, and the number of plies of nozzle is limited, so the efficiency of dust collection of vertical spray tower is lower.

Vertical filler spray column, upright, horizontal water-film syclonet, efficient such as impulse type water bath desulfurization dust removing increase, but because of reasons such as resistance are bigger, energy consumption is all higher, their application or product cost is improved, or bring no small financial burden to the user.

The purpose of this utility model is to provide a kind of energy consumption lower, the horizontal spiral washing, purifying deduster that efficiency of dust collection is high.

The purpose of this utility model is achieved in that vertical spray is changed into Horizental showering, allows the water of each water spray ozzle ejection form one cascade in exhaust gases passes; Become adverse current into crossing current, allow the subvertical direction of ash-laden gas and cascade wear curtain and mistake, captive grit quantity will be multiplied when ash-laden gas is by cascade like this.Effectively utilize the space for reducing floor space, exhaust gases passes is done spirality, this just need set up inner core and spiral guiding plate in the cylindrical channel of garden.The quantity of the quantity decision passage of deflector.Fig. 1 is the horizontal single-screw type washing, purifying desulfation dust-extraction device that weldering a slice spiral guiding plate (3) forms between shell (1) and inner core (2), is called for short horizontal spiral washing, purifying deduster.Fig. 2 is the horizontal double helical form washing, purifying desulfation dust-extraction device that two deflectors of weldering (3) form between urceolus (1) and inner core (2), promptly horizontal double helix washing, purifying deduster.For allowing mortar sink the what bottom, connect a large water tank (5) that connects together and form by several mortar buckets in horizontal cylindrical outer casing bottom, garden with flange, for allowing unnecessary water flow away, the overflow pipe (6) of band water seal is housed above water tank, its cross section of enclosure interior is shank folder weldering one sparge pipe (4) of obpyriform core body (2), and the water of its ejection forms cascade above water tank.A plurality of water spray ozzles (4) parallel with the deduster axis are housed on the shell (1) of spirality channel, the water of each sparge pipe ejection all forms one cascade on the ash-laden gas passage, the water of its upper end hole and the ejection of assorted hole splashes deflector and inner surface of outer cover and forms moisture film thereon, and the water of the sparge pipe ejection of shell upper is fallen on the inner core and formed moisture film in its surface.

After an end entered deduster, when the effect lower edge of thermal pressure spirality channel flowed, the grit that collides with cascade and moisture film was promptly caught by water and is fallen into water tank from the ash-laden gas of kiln or boiler; When the part grit flow to water tank top near the water surface, fall in the water tank in the synergy of flow rotating inertia force and gravity; Contain SO ₂Etc. gas poisonous, evil, and during fully contacting, the water that is added with desulfurizing agent also dissolves in the water.Gas through purifying like this, by the other end through air-introduced machine or directly enter smoke stack emission in atmosphere.

The deduster water is supplied with by IS80-65-125 type centrifugal water pump.Water unnecessary in the water tank enters cistern after overflow pipe flows out.Water recycles, regularly neutralisation treatment.

Advantage of the present utility model is: exhaust gases passes is roomy, and the cascade resistance is little, and when chimney foot energy was high, reliable atural beat pressure overcame resistance, and purified gas is directly sent into smoke stack emission in atmosphere; When needs add air-introduced machine,, do not need big air-introduced machine, so energy consumption is little just for overcoming the resistance of deduster itself yet.

Because Horizental showering and ash-laden gas are horizontally through the design of cascade and multi-functional dedusting, purifying and dedusting efficient is improved, can reach first discharge standard as roughly estimated.

The utility model compact conformation, floor space and space are little, and stable performance is easy and simple to handle, and water such as recycles at reason, and investment is low with operational and administrative expenses.

When this horizontal spiral washing, purifying deduster was used on five tons of coal-burning boilers or the 160 tons of flame-proof kilns, the installed capacity of a complete set of equipment electricity consumption was 10～15kw.This and the five tons of boilers in middle school, Taiyuan City adopt impulse type water bath desulfurization dust removing, and a complete set of equipment installed capacity is 54kw; It is that 47.5kw compares that 160 tons of kilns of certain refractory factory adopt the installed capacity of vertical filler spray column a complete set of equipment, and the utility model can economize on electricity about 70%.

Claims

1, the present invention is a horizontal spiral washing, purifying deduster, it is characterized in that on the shell (1) of spirality channel a plurality of water spray ozzles (4) parallel with the deduster axis being housed, and the water of its ejection forms the multiple tracks cascade on spirality ash-laden gas passage; The overflow pipe (6) of being with water seal is equipped with in the top of the large water tank of being made up of several mortar buckets (5) that connects with flange in cylindrical outer casing bottom, garden; The shank that in its cross section of enclosure interior is obpyriform core body (2) is welded with sparge pipe (4), and the water of its ejection forms cascade above water tank.
