Description
The utility model relates to a kind of unidirectional air inlet, one-stage centrifugal formula blower, especially a kind of washing, purifying blower.
Centrifugal blower is to adopt the blade impeller rotation to produce centrifugal force, makes the gas medium of conveying obtain the common equipment of outwards carrying behind the booster and speed-increasing, can be divided into air-blaster, flue gas blower, gas-blowing engine etc. according to the medium difference of being carried; Because flue-gas temperature is high and contain a large amount of dusts, so require to set up dusting apparatus before blower, makes dust removal efficiency more than 85%, and requires bearing housing is adopted water-cooled.In addition, blower can not be run well because the tar and the dust that contain in the coal gas easily adhere to impeller and casing, thus require before blower, to set up tar-removing device, require the regular dismounting blower fan to carry out decoking or with steam except that tar.The D110-12 type blower made from Shanghai Blast Fan Factory is an example, this blower fan is the coal gas pressurized delivered that is specifically designed to the factories and miness gas station, this blower is directly to borrow coupling to drive by asynchronous motor, its rotor is cantilever shape, gyratory directions is clockwise, the active wheel of riveted construction is housed above, have the blade that the high-quality carbon steel strikes out flute profile on the wheel, blade is the back musical form, and the blower casing is the plain cast iron volute body, and both sides are fixed by the casing cover plate, the intake grill direction is a side direction, the exhaust outlet direction is the 0 ° of direction in left side, between main shaft and the casing seal arrangement is housed, and whole casing spare and pipeline are tightly air tight.The technological requirement of this blower is as follows: 1. the applying unit coal gas that should manage will feed in the blower purifies in advance, influence runs well on impeller and the casing otherwise the tar in the coal gas can stick to, other one-tenth branch chemically reacts and produces corrosion in the coal gas, thereby the reduction fan performance, even damage accident.To guarantee blower abnormal heating phenomenon that do not have when 2. normally using, not allow coal gas in blower fan, to reflux, should guarantee that tar and impurity are strict to purify; Require regular check record working order.To feed steam flush tar when 3. stopping, cleaning machine intimate tar and impurity.4. General provisions every light maintenance half a year once, annual overhaul is once.
The Y-6-73-11 type boiler smoke induced draught fan of making for another the air-blower plant, Jilin, this blower fan is the induced draught system that is applicable to steam boiler in industrial and mining enterprise, the firepower electrical plant, can be divided into two kinds of blower fan patterns of anticlockwise and right rotation, there are seven angles the exit position of blower fan.Motor is connected with blower fan and all adopts the transmission of elastic coupling flexible coupling direct connection, the blade that the impeller of induced draught fan is cut sth. askew by 12 hypsokinesis wings is welded in the middle of the shroud and plate shaped hub disk of arc taper, casing is the volute body that is welded with general steel plate, volute body has been done suitable thickening with abrasionproof, intake grill adopts reducing-pitch thread streamline overall structure, is fixed by bolts to the fans entrance side.Regulate the adjustment doors of compressor flow, axially be installed in the intake grill front, induced draught fan has water-cooling apparatus in order to cooling bearing seat.
The medium that boiler induced-draft fan is carried is a flue gas, technological requirement: 1. before induced draught fan, must install dust removal apparatus additional, and few as far as possible with dust loading in the flue gas that guarantees to enter blower fan.According to one power plant's use condition, dust removal efficiency must not be lower than 85%; 2. the maximum temperature of flue gas must not surpass 250 ℃, and higher because of gas temperature, bearing support must adopt water-cooling apparatus; 3. to regularly remove the inner dust stratification of blower fan, impurity such as dirt and water; 4. the pollutant that drains in the atmosphere of environmental protection requirement is as far as possible few, require to set up purification plant behind the induced draught fan, and most of steam boiler flue gas all adopts because the purification plant expense is high.
In sum, deficiency on the existing blower performance mainly shows what fan design person only manufactured and designed blower fan as single pressurized delivered gas apparatus, can only be no more than 80 ℃ by delivery temperature on its performance, comparatively clean, not can with the gas medium of body material generation chemical reaction, therefore the mixed gas that contains many kinds of compositions in conveying, and when it contains impurity such as viscous drop and dust, can only be by other device before blower, the impurity that is unfavorable for fan performance in the gas is removed, made the cleaning gas, the normal temperature that enter blower fan.
The purpose of this utility model is for but a kind of both washing, purifyings conveying gas medium is provided, but again washing, purifying blower body and can prevent that gas medium from leaking, safety, simple washing, purifying blower.
The purpose of this utility model can realize by following measure:
A kind of washing, purifying blower comprises intake grill, liquid film casing, impeller, main shaft, bearing support, air outlet tube; Spindle nose at the impeller bonnet place of intake grill end is equipped with separatory and is equipped with cap; Separatory is equipped with cap and is with shower nozzle outward, and shower nozzle links to each other with liquid inlet pipe; Described impeller is the liquid film impeller, and the blade of liquid film impeller extends to the center and is reducing-pitch thread and links to each other with liquid film impeller bonnet.
The utility model has following advantage compared to existing technology:
1, the utility model is on existing blower foundation; add a cover hydrojet washing purifying device; promptly adopt shower nozzle and separatory to be equipped with cap at draught fan impeller bonnet place; the blade surface at impeller forms liquid film layer on the impeller bonnet thereby the liquid that liquid inlet pipe is carried is ejected to; can protect blade, and isolated impurity from gas is taken away in absorption.
2, the blade of impeller of the present utility model is reducing-pitch thread from original basis and extends to the axle center; the blast flow that provides gas medium enough can be provided; and can make feed liquor be evenly distributed on each surface of running blade, and on each surface, all form liquid film layer, thus protection blade Purge gas medium.
3, behind the liquid film impeller operation of the present utility model, the liquid film that the current that spill from impeller outlet form can protect the casing surface not adhere to impurity the gas phase, and can take away isolated impurity from gas phase.
4, blower fan of the present utility model not only can be carried the equipment of superheated steam medium, also can be used as the equipment that reclaims the valuable medium in the gas phase and uses.
5, the utlity model has the self-cleaning function, so casing inside remains cleaning, it operates steadily, and prolong working life, and need not the special messenger and guard operation.
