Abstract

The utility model discloses a vortex type boiler dust catcher, which is composed of a casing, a smoke vent, a wind collection chamber, a smoke inlet, a filtration bed, an S type vortex chamber, a wash reaction groove, a cone bucket, a spray head, a make-up tank, an overflow pipe and a blow down valve, wherein, the cone bucket is arranged at the bottom of the inner cavity of the casing; the wash reaction groove is positioned above the cone bucket. The spray head is arranged in the S type vortex chamber which is composed of partition plates above the reaction groove; the filtration bed is arranged above the vortex chamber; expanded shale is laid on the filtration bed. Spray is stirred up by that smoke passes through a reaction zone of the S type vortex chamber, and a water curtain is formed; the smoke and dust are separated by the shock at the first time, and a second level clarification is formed by that a reflection-shaped water curtain is formed by spraying through a water fender; then, the third level clarification is made when the smoke and the dust pass through the filtration bed and the expanded shale; the expanded shale has strong adsorption properties, so sulfides and coal-tar oil in the smoke and the dust can be absorbed, and the sulfides and the coal-tar oil can be repeatedly washed away at definite time.

Description

The spiral vortex type boiler dust remover

Technical field

The utility model relates to the equipment of gas cleanings such as a kind of Industrial Boiler smoke dispersal, dust removal and desulphurization.

Background technology

According to statistics, about 2,000 ten thousand tons of the annual flue dust total amount of discharging from Industrial Boiler in the whole nation simultaneously also with pernicious gases such as SO2, has seriously been polluted environment, and production, people's lives and health of human body have all been caused great harm.The Industrial Boiler smoke dust-removing equipment has multiple pattern, generally can not thoroughly solve anti-pollution problem.

The utility model content

The purpose of this utility model is to provide a kind of spiral vortex type boiler dust remover, has smoke dispersal, dust removal and desulphurization effect efficiently.

The utility model technical solution: the spiral vortex type boiler dust remover by housing, exhaust opening, remittance air compartment, advance mouth, filter bed, S type minor air cell, washing reaction groove, awl bucket, shower nozzle, extra feed tank, overflow pipe and blowoff valve and form, the housing intracavity bottom is provided with the awl bucket, awl bucket top is the washing reaction groove, the reactive tank top constitutes S type minor air cell by dividing plate, dividing plate and water fender constitute air water and divide the fog chamber, the indoor shower nozzle that is provided with, air water divides the top, fog chamber to be secondary smoke elimination chamber, top, smoke elimination chamber is provided with filter bed, and haydites of book structure is assisted and is being provided with on the filter bed of screen cloth.

The utility model boiler dust remover, flue gas is through the S type eddy current reaction zone formation water curtain that swashes the foam of breaking waves, for the first time flue dust is separated through bump, promptly the one-level clarifying smoke produces the reflection water curtain through water fender and spray, be secondary purification this moment, when the haydites of book structure filter bed, play third level catharsis then, haydites of book structure filter bed adsorptivity is strong, sulfide in the adsorbable flue dust, but haydites of book structure periodic flushing.

Fig. 2 is the utility model spiral vortex type boiler dust remover left view.

The specific embodiment

As shown in the figure, deduster top is made up of exhanst gas outlet 1, remittance air compartment 2, haydites of book structure filter bed 4 and manhole 3, the middle part is a gas approach 5, inner chamber constitutes secondary smoke elimination chamber by division board 15 and shell body, division board 6 constitutes carbonated drink with water fender 7 and divides the fog chamber, division board 8 and 9 constitutes S type minor air cell, division board 15 constitutes the flue gas diffuser casing with division board 6, two division boards 9 constitute the washing reaction groove, shower nozzle 14 divides fog chamber's spray to carbonated drink, hull outside is provided with extra feed tank 10 and overflow pipe 16, and being supplied water by immersible pump sprays.Lower housing portion is made up of cone 11 and butterfly type blowoff valve 12, and entire equipment is supported by support 13.

The utility model operation principle is: the flue gas of boiler enters the flue gas diffuser casing by gas approach 5, in the flue gas diffuser casing because the malleation of boiler and the effect of exhanst gas outlet negative pressure, the flue gas diffusion also enters the washing reaction groove, dust that it is heavier and particle fall into awl bucket 11, all the other flue gases enter S type minor air cell and form S type eddy current jointly with water outside liquid levels, the flue gas of deviating from the water surface rises to carbonated drink branch fog chamber, behind shower nozzle 14 sprays, continue to rise to secondary smoke elimination chamber, after filtering, the haydites of book structure filter bed enters the remittance air compartment again, flue gas this moment purifying and dedusting fully is by exhaust opening 1 discharge.

The utility model deduster characteristics are: flue gas is through the washing reaction groove time, and it is heavier Particle directly sinks in the cone bucket; Under the effect of S type eddy current, make sulphur and water in the flue gas fully anti-Should, and water-soluble, carbonated drink is divided under the effect that sprays the fog chamber in, and carbonated drink is fully separated; Flue gas After separating, still there are the unburnt charcoal of part and coal tar to enter the auxiliary filter bed that haydites of book structure arranged again Filter, wherein unburnt charcoal and coal tar are adsorbed by the shale particle, through the cigarette behind the depth filtration, deep bed filtration The dustiness of gas generally about 3-4%, is significantly less than the discharge standard of national regulation.
