Description
Full-automatic computer soot blower described in the utility model, relate to coal and oil boiler and superheater, economizer, air preheater and various industrial equipment in each factory, the steam power plant, especially to the double-drum boiler convection bank in the boiler, has energy-efficient deashing effect.This device cleaning efficiency height, little power consumption can improve the combustion thermal efficiency of boiler, and energy savings belongs to desirable environmental protection blowing device.
Dust stratification is coal-fired and oil burning boiler heating surface and auxiliary equipment ubiquitous problem in service thereof.Boiler long-play such as untimely deashing, heating surface easily accumulates dust, increases thermal resistance, influences ventilation and air output in the burner hearth, causes fuel not burn rapidly, thereby has reduced the thermal efficiency of boiler.Dust stratification stops up flue easily when serious, makes that boiler can not normally move, fire door is burnt, and contaminated environment also causes energy waste (when dust thickness reaches 1mm according to surveying and determination, waste fuel about 10%).Dust stratification also makes the resistance of the deduster in the auxiliary equipment increase, and reduces efficiency of dust collection, and the power consumption of air-introduced machine is increased, and influences unit operation simultaneously.
The soot blower that uses mainly contains two kinds of air compressor soot blower, high steam soot blowers at present.The effective range of air compressor soot blower is less, and air quantity is little, and is especially little to viscoplasticity ash effect.The high steam soot blower, steam consumption is big, the dust in easy-clear local angle does not fall.Make when blowing ash in the boiler and produced malleation in the ventilation process, influence the normal operation of boiler, reach the efficiency of dust collection of deduster in the boiler auxiliaries, caused serious atmosphere pollution, also strengthened power consumption.More than two kinds of soot blowers all by manually-operated, labour intensity is big, and can not accomplish timely deashing every day.
The purpose of this utility model is that a kind of current collection brain switch of proposition, automatic switch valve, high pressure positive blower, high pressure soot-blowing nozzle and electric device soot blower are the new automatic computer soot blower of one.To overcome limitation and the shortcoming that existing boiler soot-blowing equipment exists, make that soot blower turns round automatically, timely deashing, guarantee the operate as normal of boiler and deduster.Can also reduce hand labor intensity.
Description of drawings: figure is the structural representation of utility model.
Best-of-breed technology scheme of the present utility model is described in further detail scheming. This structure is by blast pipe (1) high pressure positive blower (2) Automatic switch valve (3) airduct (4) computer switch (5) wind adjusting hole (6) electric device (7) bearing (8) air register (9) Retainer ring (10) the remittance heat insulation connector of air compartment (11) ajutage (12) (13) thrust ball bearing (14) fixed head (15) The compositions such as wearing bush (16) high speed soot-blowing nozzle (17) fresh air inlet (18).
Essence of the present utility model be adopt computer switch (5) automatic switch valve (3) electric device (7) air register (9) to converge the heat insulation connector of air compartment (11) ajutage (12) (13) thrust ball bearing (14) high speed soot-blowing nozzle (17) and formed self-timing running, high-pressure blowing-in, blowing ash is the full-automatic computer soot blower of one at a high speed, boiler can be run well, the efficient dust of removing in boiler and the various device, improve the ventilation in the boiler, add the heating surface in the cauldron, improve the thermal efficiency of boiler, and saved the energy.
The utility model utilizes blast pipe (1) to be connected with the blower export of boiler, makes the air quantity in the boiler constant, has improved the air output of high pressure positive blower (2).Increased automatic switch valve (3) between high pressure positive blower (2) and the airduct (4) and when blowing ash, opened automatically, closed automatically when blowing ash and finishing, made boiler blower recover the air output of bottom in stove.Having increased computer switch (5) control between automatic switch valve (3) and the wind adjusting hole (6) blows startup, the dwell time of ash and blows grey number of times (can determine according to the concrete ruuning situation of boiler and the ature of coal of coal).Ajutage (12) left end has increased electric device (7), has finished rotation and has stopped.There is bearing (8) to improve the rotation amount of ajutage (12) between electric device (7) and the air register (9).There is air register (9) to help the stability of wind speed in the remittance air compartment (11).There is remittance air compartment (11) to guarantee the storage of air quantity and the supply of blast between retainer ring (10) and the ajutage (12).Increase heat insulation connector (13) between ajutage (12) and the thrust ball bearing (14), increased thrust ball bearing (14) between heat insulation connector (13) and the fixed head (15).Thrust ball bearing (14) and wearing bush (16) link together, be fixed on this device on the boiler metope and the cylindrical shell of various device on, prevent the refractory material vibrations of boiler wall and the wearing and tearing of ajutage (12).Ajutage (12) left end remittance air compartment (11) is the air inlet of ajutage (12), and right-hand member is the air outlet of ajutage (12), and this end has 1 to a plurality of high speed soot-blowing nozzles (17), and the shape of high speed soot-blowing nozzle (17) on ajutage (12) is T shape.The shape of high speed soot-blowing nozzle is taper.A plurality of fresh air inlets (18) are arranged on the air register (9).
The utility model full-automatic computer soot blower structure is connected with the boiler blower air outlet by adopting blast pipe (1), has guaranteed the stability of the air output in the boiler.Utilized automatic switch valve (3) when not blowing ash, to control ventilation in high pressure positive blower (2) and the boiler.Computer switch (5) can be adjusted and blow ash start-up time, dwell time and blow grey number of times.Electric device (7) has reduced manually-operated.Bearing (8) has guaranteed the normal operation of ajutage (12), prevents wearing and tearing.Heat insulation connector (13) has prevented that the lubricating oil in remittance air compartment (11) inner bearing (8) is heated and has flowed out and the thermal deformation of rubber gasket.Thrust ball bearing (14) has formed the bracing frame of ajutage (12), has guaranteed the balance of ajutage (12), has reduced the power consumption of electric device (7), has prevented the vibrations of boiler wall.High speed soot-blowing nozzle (17) can be removed the dust stratification of all positions in boiler and the various device.More than finish full-automatic timing and blown ash, reduced manually-operated, the dust that accumulates in boiler and the various device is eliminated rapidly, reached best effect.
The utility model full-automatic computer soot blower, essence is that the high-pressure blast that has adopted high pressure positive blower (2) to produce is sent into remittance air compartment (11) by automatic switch valve (3) release, rotate by electric device (7), supply with high speed soot-blowing nozzle (17) through ajutage (12), the high-speed jet of keeping watch has been finished high efficiency energy-conservation deashing to the dust stratification place.Experimental results show that: blowing ash start-up time, dwell time and blow grey number of times can be definite voluntarily according to the ruuning situation of boiler.Blow grey efficient height, remove the dust stratification rate and reach more than 96%, can improve the thermal efficiency about 5% of boiler, save coal about 10%, and can also reduce the lingemann blackness of flue gas.This structure has novelty, creativeness, practicality, also has advantages such as little power consumption, energy savings, stable performance, long service life.
