Abstract

The invention relates to an environmental dust remover of a boiler. The top of an outer housing of a dust removing chamber is provided with a fume inlet pipeline which is communicated with an inner housing, and the lateral part of the outer housing is provided with a fume outlet pipeline which is communicated with the inner of the outer housing; the bottom of the outer housing is provided with a dust discharging opening provided with a valve; a dusting cleaning pool corresponding to the dust discharging opening is arranged below the outer housing, the outer lateral wall of the outer housing is welded with a water tank, and the water tank is communicated with the inner part of the outer housing by a water inlet with a valve. The inner part of the inner housing is provided with a whirlwind dust remover close to the middle part, a whirlwind dewaterer is arranged between the inner part of the inner housing and the outer housing, close to the bottom, and the inner wall of the outer housing is welded with a cambered water guide board, which is arranged above the whirlwind dust remover. Compared with the prior art, the dust remover has the advantages of dust removing, high desulphurization efficiency, little water content of flue gas, no influence on the operating effect of the boiler, and the like.

Description

A kind of environment-protection boiler deduster

Technical field

The present invention relates to a kind of cleaner, relate in particular to a kind of boiler dust remover.

Background technology

Boiler dust remover is the necessary component of coal-burning boiler system, has the effects such as dedusting, desulfurization because of it, is an indispensable part in boiler operatiopn system always.Existing boiler dust remover mainly divides ceramic multi-tube cyclone dust collectors, wet type desulfurizing dust collector, sack cleaner and electrostatic precipitator, and being mainly large-sized station boiler, latter two uses, the current Industrial Boiler of China is to take first two as main, and ceramic multicyclone dust collector is two because can only reach dust removing effects, cannot get rid of the sulphur in flue gas, substantially also in eliminating state, therefore, the existing Industrial Boiler of China mainly be take wet type desulfurizing dust collector as main, existing wet type desulfurizing dust collector its by air inlet, dedusting guide plate, dewatering plate, air outlet four parts form, and can install spray equipment additional between air inlet and dedusting guide plate, to improve efficiency of dust collection, in the process of using, if do not installed spray equipment additional, efficiency of dust collection is low, and easily stop up dedusting guide plate after installing spray equipment additional, in use procedure, fault rate is high, affect boiler operatiopn effect and efficiency, existing wet boiler desulfurizing dust-collector can not meet user's user demand.

Summary of the invention

The object of the present invention is to provide a kind of efficient, environmental protection, stable environment-protection boiler deduster, its not only dedusting, desulfuration efficiency are high, flue gas water content is little, do not affect boiler operatiopn effect, and structure, technique are simple, flexible arrangement, floor space is little, be convenient to maintenance, meet the environment-protection boiler deduster of user's user demand.

The present invention mainly includes underframe, dirt pocket, smoke-intake pipe road, smoke pipeline, valve, ash removal pool, water tank, water inlet pipe, cyclone dust collectors, whirlwind devulcanizer and weather board, wherein the bottom of dirt pocket is by supporting with the underframe of its welding, described dirt pocket is that shell and inner casing form by two hollow housings, wherein the enclosure of sealing is established up and down all inner casings of opening, the upper end end wall of inner casing and the inner roof wall of shell weld together, described cover top portion is provided with the smoke-intake pipe road being communicated with inner casing, the sidepiece of shell is established the smoke pipeline communicating with its inside, ash discharging hole is established in the bottom of above-mentioned shell, and ash discharging hole place establishes valve, the ash removal pool corresponding with ash discharging hole established in the below of described shell, the grooved housing that ash removal pool is upper shed, the lateral wall welding water tank of above-mentioned shell, water tank is with valvular water inlet pipe to be communicated with enclosure by one, and best, water tank is provided with water level balance device, the inside of above-mentioned inner casing is provided with cyclone dust collectors near medium position, and these cyclone dust collectors are bolted on the inwall of inner casing, best, on the lower end end wall of described inner casing, weld the metallic plate of arc, i.e. dust-leading board, the recess of this dust-leading board arranges downwards, between above-mentioned inside and shell, near lower position, be provided with tornado evaporator, this tornado evaporator is bolted on the inwall of shell, the metallic plate of some arcs is welded on the inwall of above-mentioned shell and the top that is positioned at tornado evaporator, be weather board, the equal recess of these weather boards arranges downwards.

Best, the inwall of the inwall of above-mentioned inner casing and outer wall, shell and the outer wall of the dust-leading board rotten dope layer of all setting up defences.

The present invention adopts the form of inner casing and shell combination, and inner casing is set up cyclone dust collectors, flue gas is entered after inner casing by smoke-intake pipe road, flue gas curl paving is to the water surface of outer casing bottom, make velocity of flue gas faster, flue gas and the water surface clash, mix, strengthened dust removing effects, install dust-leading board simultaneously additional and can more improve mixed effect, between inner casing and shell, set up tornado evaporator, humid flue gas is discharged in the shape of a spiral, because water is heavier than air, water is because inertia is close to outer casing inner wall, by weather board, flow back to outer casing bottom again, the ash removal pool of outer casing bottom is convenient to clear up dust and the waste water of enclosure, the present invention has not only significantly improved dedusting, the desulfuration efficiency of deduster, and has reduced the water content of flue gas, greatly extends the service life of coupled equipment.
