Description
Technical field
This utility model relates to a kind of air preheater High-Pressure Water injection apparatus, is specially a kind of Moveable high-pressure water flow jet
Device, belongs to high pressure water washing technical field.
Background technology
Air preheater is also called air preheater for short, is to improve boiler hot switching performance, reduces a kind of pre-of thermal losses
Hot equipment.It is the heat carried in the flue gas just discharged in boiler back end ductwork, by fin conductive to entrance boiler
In front air, by air preheat to certain temperature.From the point of view of Current Domestic each power plant present situation, empty pre-cooling end low temperature is rotten
Erosion, clogging phenomenon, be generally to have problems at present, and improvement is difficult to.Due to the stifled ash of air preheater corrosion, cause boiler exhaust gas
Temperature raises, and hot blast temperature declines, and air-supply positive pressure side and air draught suction side two press side pressure difference to increase, and increases air preheater leakage
Wind.Time serious, air-introduced machine is without pondage, causes combustion chamber draft to be difficult to maintain, and has influence on the input of burning automaton.Empty pre-
The differential pressure rising of device both sides can have a strong impact on the safe operation of large coal-fired boiler, and stifled ash is the main cause this problem occur, from
Operating experience is seen, depending merely on selective sootblowing is to be not enough to control the stifled ash of air preheater and the rising of pressure drop.Therefore, air preheater once arrives
Reaching the corresponding use cycle is accomplished by heat exchanging element and is rinsed.Backwashing manner mostly is blowing out, treats that air preheater is down to room temperature
After use artificial giant that air preheater is rinsed again.Owing to air preheater cold-end air black dirt layer may be very rigid, use
Ash cannot be washed out by normal developing method, it is necessary to uses the artificial high pressure water washing of specialty to be washed out by black dirt.But high pressure is artificial
Water flushing pressure easily causes heat exchanger fin edge-curl phenomenon, more easily causes stifled ash.And every air preheater high pressure water flushing every time
Wash expense all at about 150,000 yuan.
There is artificial flushing time-consumingly long, developing result instability, the shortcoming of poor stability in existing method, by artificial punching
Washing and use the mode of single single rifle to carry out in flushing, if the many people in same cross section, multiple gun are carried out, danger is relatively big, and walking rushes
Cleaning device successfully solves problems, and artificial flushing uses the mode of single single rifle to carry out, due to by people in rinsing work
The impact of the aspect factor such as physical ability, trail is difficult to keep certain, and this most greatly have impact on developing result, adds flushing
Time.Use flusher that class can be avoided to be that thing occurs, greatly improve developing result and working time.
For solving the problems referred to above, currently proposed a kind of Moveable high-pressure water flow spraying device.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of Moveable high-pressure current
Injection apparatus.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one Moveable high-pressure water flow spraying device, including water knockout drum, deceleration device, urgent blowdown and row
Walking apparatus, the side of described water knockout drum is provided with water inlet, discharge outlet and relief valve connection, described water knockout drum be arranged over n
Individual nozzle, and the position corresponding with nozzle be provided with n plug, described deceleration device includes decelerator and hand-operated wheel, described hand
Wheel be positioned on described decelerator, described running gear is positioned at the lower section of described water knockout drum, described running gear include road wheel and
Walking track, described walking track is positioned at inside described road wheel.
Further, the side of described running gear is provided with balancing weight.
Further, described walking track is dies.
The beneficial effects of the utility model are: this utility model patent occurs stifled ash to be arranged on when needing and rinse at air preheater
The cold end position of air preheater, uses high-pressure hydraulic pump to provide rinse water, and flusher arranges nozzle quantity according to high-pressure hydraulic pump flow, subtracts
Lack manual operation, it is achieved air preheater high-efficiency washing, replaced artificial flushing by a kind of flusher, reduce water under high pressure to behaviour
Making the infringement of personnel, saved human resources, nozzle is constant relative to air preheater heat exchange element position simultaneously, equal pressure rating bar
Rinse better under part.
