Description

A kind of electricity generation boiler soot blower system

Technical field

The utility model relates to boiler soot-blowing technical field, specifically a kind of electricity generation boiler soot blower system.

Background technique

Electricity generation boiler passes through burning combustible gas or energization at work, heats to the object that need to be heated, any combustion Coal or oil burning boiler in the process of running, can all generate dust stratification, knot on the equipment inner surface such as burner hearth, high temperature superheater, flue The problems such as slag even blocks, the serious thermal efficiency and utilization rate for reducing furnace body, or even the safe operation of boiler can be jeopardized, at present Deashing, scale removal and decoking generally are carried out to boiler using boiler sootblower, the prior art is the impact force by working media Dust stratification is washed away, working media will lead to boiler tube and different degrees of abrasion and corrosion occurs during ash disposal, shorten boiler tube Service life.

Utility model content

To solve the above problems, the purpose of the utility model is to provide a kind of electricity generation boiler soot blower systems.

The utility model to achieve the above object, a kind of electricity generation boiler soot blower system, soot blowing circuit shell including U-shaped and Built-in sonic generator, the upper and lower ends of soot blowing circuit shell are horizontal simultaneously be connected to furnace body, and soot blowing end positioned at into The lower section at gas end is open for loudspeaker, and inside is fixed with a plurality of symmetrical above and below and inclined demarcation plate, and sonic generator is mounted on Close to the position of loudspeaker opening, shaft is installed in the seal closure of the other side support of sonic generator and stretches out the electronic of seal closure Machine fixes the flabellum of oriented sonic generator blowing in the shaft of motor, and position connects among the inlet end of soot blowing circuit shell Be connected with oil storage box, be separated by partition among oil storage box, partition lower end and oil storage box there are gap, filled in oil storage box it is enough can The oil plant for absorbing cigarette ash can also use other such as 320 DEG C of conduction oils that Jiangsu force English hot oil pump conduction oil Co., Ltd produces Grease resistant to high temperature, main purpose are to carry out dust suction to the gas of process by the oil of liquid, and the bottom of oil storage box is additionally provided with The connection oil valve being in communication with the outside.

Traditional soot blower system often takes out air from the external world and utilizes ultrasonic impact boiler inner sidewall, can drop in this way The temperature of low boiler, in order to guarantee that temperature some also needs to heat, the energy can be greatly increased again by heating the air that this part is blown into Consumption, also have and soot blowing directly carried out to boiler internal using itself air in boiler, but structure design it is not reasonable, not enough tightly Gather, cause pilot process thermal losses serious, and do not have flue dust absorb and filter capacity, Boiler Ash be intended to inner accumulation, It being difficult to effectively be discharged, the utility model can not only efficiently use the hot gas in boiler and carry out soot blowing to boiler inner sidewall, And the gas of entrance effectively can be filtered and be adsorbed by the inlet end of device, effectively remove the cigarette ash in gas, really The gas for protecting blowout is cleaner, substantially increases whole soot blowing effect.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, a kind of electricity generation boiler soot blower system, soot blowing circuit shell 1 and built-in sound including U-shaped Wave producer 2, sonic generator 2 be acoustic wave ash ejector resistant to high temperature, as patent of invention CN200410060522.7 announce it is whole Body formula high temperature high efficiency acoustic wave ash ejector, can meet use, naturally it is also possible to using other high temperature resistant acoustic wave ash ejectors, blow The upper and lower ends of grey circuit shell 1 are horizontal and are connected to furnace body 3, and soot blowing end is located at the lower section of inlet end, are open for loudspeaker, and Inside is fixed with a plurality of symmetrical above and below and inclined demarcation plate 4, and sonic generator 2 is arranged close to the position of loudspeaker opening, sound The motor 6 that shaft stretches out seal closure 5, the shaft of motor 6 are installed in the seal closure 5 of the other side support of wave producer 2 The inlet end centre position of the flabellum 7 that the upper oriented sonic generator 2 of fixation is dried, soot blowing circuit shell 1 is communicated with oil storage box 8, Separated among oil storage box 8 by partition 9,9 lower end of partition and oil storage box 8 there are gap 10, the bottom of oil storage box 8 be additionally provided with The connection oil valve 11 of external world's connection.

In order to improve the efficiency of circulation, 7 air inlet one end of flabellum in soot blowing circuit shell 1 is provided with water conservancy diversion inclined-plane 12, leads The reflecting surface on stream inclined-plane 12 will go into wind herein and be reflected at flabellum 7.

One layer of heat preservation material 13 is enclosed with outside soot blowing circuit shell 1, this layer of thermal insulation material 13 can all cover all Component, better heat insulation and preservation effect can be played in this way, so that the loss of boiler heat be effectively reduced.

The inlet end and exhaust end of oil storage box 8 are respectively fixedly connected with the inclined baffle 14 of oriented partition 9, wherein oil storage box 8 It is further fixed on filtering backstop 15 between 1 side wall of baffle 14 and soot blowing circuit shell of exhaust end, passes through baffle 14 and filtering backstop 15 force air-flow herein retarded, and play good filtration, clean the wind of blowout more, improve whole Soot blowing effect.

Work makes to enter high-temperature gas by 1 upper end of soot blowing circuit shell, and 15 mistake of backstop is filtered and filtered by oil storage box 8 Filter, removes a large amount of cigarette ash in high-temperature gas, clean high-temperature gas pass through again sonic generator 2 and flabellum 7 blow into Enter in boiler 3, achieve the purpose that soot blowing and inhale ash, is more advantageous to boiler side walls and keeps clean.

The standardized element that the utility model uses can commercially, shaped piece according to specification and attached drawing Record can carry out customized, the specific connection type of each part is all made of in the prior art mature bolt, rivet, weldering Equal conventional means are connect, this will not be detailed here.

Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, this The those of ordinary skill of technical field, in the essential scope of the utility model, variation, change, addition or the replacement made, all It should belong to the protection scope of the utility model.
