Abstract

The utility model belongs to a dust remover for boilers, particularly an energy-saving efficient desulfurizing dust remover which is characterized in that a core pipe which is extended upwards and an annular water tank are arranged on a shaft on the upper part of a dust remover, the lower end opening of the core pipe is fixedly connected to a flow guide blade, and a conic ash bucket which is provided with an ash discharging opening is arranged on the lower part of the inner cavity body of a casing, and extended into a bracket. The utility model has the advantages of many functions, light weight, small land occupation area, convenient operation, etc. The utility model has the same cost with the dust removers which only have the dust removing function, and has the competitive edge in market. Meanwhile, the utility model opens up a broad prospect for the desulfurizing type dust removers used in the cold areas or the northeast of China.

Description

The desulphurization energy-saving high-efficiency dust remover

The utility model belongs to dust-removing device for boiler.

Remove atmosphere pollution, the control boiler soot emission is that relevant department very pays close attention to always.What be usually used in boiler dusting is cyclone dust collector, and it can only be used for dedusting, does not have the sulfur functional of removing.The ash mouthful dust of discharging makes kettleman's work situation become bad, has influenced the healthy of kettleman.

The purpose of this utility model provides a kind of dedusting that has, sulphur removal, and power saving function, and can improve the dust arrester of kettleman's work situation.

The purpose of this utility model is achieved in that

It has upper lateral part and is provided with housing with boiler dust-exhausting port adpting flange, and lower housing portion is ash bucket and dust-exhausting port, is provided with core pipe and annular water tank in the housing.It is characterized in that deduster housing (8) upper axial is provided with stretches and the core pipe (5) and the perisporium annular water tank (9) of the affixed guide vane of lower port (10), and the taper ash bucket (13) of housing (8) inner chamber body bottom band ash discharging hole (16) extends in the support (14).

Advantages such as it is many to the utlity model has function, in light weight, and floor space is little, and is easy to operate, dust removal efficiency is 93～97%, desulphurizing ratio is 70～75%, absorbs cigarette heat obviously, economizes on coal more than 30%.Its cost with only have the deduster of dedusting function suitable, very competitive on market.Simultaneously, use the desulfurization type deduster for China's cold district or northeast and opened up bright prospects.

Accompanying drawing is a structural representation of the present utility model

The set guide vane of housing inner core tube of the present utility model (5) lower port is 2～4; The top and bottom of annular water tank (9) are respectively equipped with delivery port (6), spilling water valve (7) and water inlet (12), blowoff valve (11).Housing (8) upper lateral part is connected to the adpting flange (3) of boiler dust-exhausting port.The built-in fog-spray nozzle (4) of putting is equipped with clean trap valve (2) and milk of lime jar (1) on the pipeline that joins with fog-spray nozzle (4).Core pipe (5) lower port guide vane (10) group that this example provides constitutes by three, is shaped as swallow-tail form.Its Main Feature: (1) owing to increased atomising device, the flue dust that enters deduster forms particle through atomizing, and not only dust removal efficiency is very high, and fabulous sulfur limitation effect is arranged.(2) enter water that the cigarette heat of deduster makes peripheral water tank after uniform temperature, with its be discharged to cistern again pump advance boiler, thereby played province's coal effect, and can replace old-fashioned boiler economizer fully.(3) the deduster body is being wrapped by water and can prolong its service life.(4) water of water tank can not only alleviate the vibration and the noise of air-introduced machine, can absorb a large amount of cigarette heat simultaneously, makes not running at high temperature of air-introduced machine, thereby strengthens service life.(5) dust forms wet type or half dry type graininess through atomizing, can alleviate the harm of dust to kettleman's health during ash discharge.What the deduster inwall adopted (6) is refractory masses, owing to be easy to come off, so service life is shorter.And the inwall of this deduster adopts is the BJ fiberglass paint, not only wear-resisting and antisepsis arranged, naturally prolongation service life.

When boiler smoke passes through the import of deduster ring flange, the lime whey is through behind the clean filter, sprayer begins to spray in import department, water smoke becomes particle A with the flue dust condensation by mixing, A has neutralized after sulfur dioxide enters deduster, because at a high speed rotation has produced centrifugal force, at this moment a part of white gas B advances chimney, particle by will stream page or leaf sheet through the core pipe row suitable for reading of deduster and reduces in the ash bucket that ring flange connects and be C, heaps after ash discharging hole is got rid of.The water of water tank is owing to absorbed a large amount of cigarette heat, the very fast rising of water temperature.Different or according to purposes for bathing pool, or through the cistern pump to boiler, reach the purpose of economizing on coal.After the long-term use of deduster water tank, sediment is discharged by sewage draining exit in the water.

Among the figure 15 is the ring flange mouth, and 16 is ash discharging hole.

Claims
