Abstract
The utility model discloses an online compressed air pulse ash remover and is applicable to the online ash removal for rotary-type air preheater of boiler in power plant, which is composed of a compressed air accumulator, a plunger valve or an electromagnetic valve, an air ejection pipe and a sequence controller. Besides, compressed air is adopted as impact energy medium to remove ash in the form of air explosion. Impact pressure and frequency are under control of programming controller and can be adjusted at random. Furthermore, the ash remover can efficiently remove new and previous ash on rotary-type air preheater and avoid soot burning in the preheater, saves energy flammable gas and oxygen, reduces cost on ash removal, simplifies structure, improves safety of large-sized boiler system and shows extensive practicality.
Description
One, technical field
The utility model relates to on-line explosive-proof type air pulse ash handling equipment, is particularly useful for the online ash disposal of boiler of power plant rotary regenerative air preheater.
Two, background technology
The boiler of power plant revolution air preheater pulse ash handling equipment that uses is at present mixed by natural gas bottle, oxygen cylinder, pressure-reducing valve, magnetic valve, gas and fires chamber, igniter, jet pipe, nozzle and form.Imflammable gas and oxygen by magnetic valve and pressure-reducing valve control during device work mix in proportion, ignition device, and the mist combustion explosion produces the high speed impact ripple, and the dust stratification in the rotary regenerative air preheater is hit fragmentation and is blown air preheater.Though this ash disposal mode effect is pretty good, because the shock wave that the combustion explosion type ash handling equipment produces is a kind of high-temperature gas of flame, therefore the coal dust in the air preheater is lighted through regular meeting, cause the burning of air preheater, cause a serious accident.
Three, summary of the invention
In view of the problem that prior art exists, the purpose of this utility model provides a kind of simple in structure, discharged at lower temperature, on-line explosive-proof type air pulse ash handling equipment that dedusting effect is good.
The utility model on-line explosive-proof type air pulse ash handling equipment, it is made of Compressed Air Energy Storage, the high-pressure pipe that links to each other with Compressed Air Energy Storage, control valve, gas spray booster and time schedule controller, the air inlet pipeline of Compressed Air Energy Storage is provided with air intake control valve, outlet is by ring flange control valve and the gas spray booster that is linked in sequence, gas spray booster top is connected with rectangular horizontal gas spray booster with it, and horizontal gas spray booster is provided with a plurality of nozzles; Time schedule controller is connected on the control valve.
The utility model on-line explosive-proof type air pulse ash handling equipment, described Compressed Air Energy Storage is provided with pressure gauge sensor; Compressed Air Energy Storage is provided with temperature sensor; Control valve can be a plunger valve, also can be magnetic valve; The both sides of horizontal gas spray booster are provided with holder.
The utility model on-line explosive-proof type air pulse ash handling equipment is best suited for the online ash disposal of boiler of power plant rotary regenerative air preheater.Adopt Compressed Air Energy Storage, plunger valve or magnetic valve, gas spray booster, with compressed air is the explosion type ash disposal of impact kinetic energy medium, can be in new, the old black dirt of removing efficiently on the rotary regenerative air preheater, avoid turning round the combustion of coal ash in the air preheater, saved imflammable gas and oxygen simultaneously, reduced the ash disposal cost, simplified the structure, promote the security of large-sized boiler system, had practicality widely.
Four, description of drawings
Accompanying drawing is the utility model on-line explosive-proof type air pulse ash handling equipment topology view.
Among the figure: the 1-air inlet pipe, the 2-air intake control valve, the 3-temperature sensor, the 4-pressure gauge sensor, the 5-Compressed Air Energy Storage, 6-plunger valve or magnetic valve, 7-sprays booster, 8-spray booster holder, 9-nozzle, 10-level spray booster, 11-time schedule controller
Five, the specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The utility model on-line explosive-proof type air pulse ash handling equipment, it mainly is made of Compressed Air Energy Storage 5, control valve 6, time schedule controller 11 and gas spray booster 7, Compressed Air Energy Storage 5 is provided with pressure gauge sensor 4, and being provided with temperature sensor 3, pressure gauge sensor 4, temperature sensor 3 screw threads are fixed on the Compressed Air Energy Storage 5.The bottom of Compressed Air Energy Storage 5 is connected with high-pressure pipe 1, high-pressure pipe 1 is equipped with the control valve 2 of controlling charge flow rate with the air inlet place of Compressed Air Energy Storage 5, Compressed Air Energy Storage 5 air inlets are connected with air delivery valve 2 one ends, and air delivery valve 2 other ends are connected with compressed air snorkel 1.Be located at Compressed Air Energy Storage 5 top exit pipes be linked in sequence plunger valve or magnetic valve 6 and gas spray booster 7, gas spray booster 7 lower ends are connected with plunger valve or magnetic valve 6 threaded one ends, the plunger valve or magnetic valve 6 other ends connect Compressed Air Energy Storage 5 outlet(discharge) flange dishes with ring flange, and time schedule controller 11 is connected on plunger valve or the magnetic valve 6.The 7 upper ends connection of gas spray booster meets at right angles with it and the horizontal gas of symmetry sprays booster 10, on the horizontal gas spray booster 10 four nozzles 9 are housed, the left and right sides of horizontal gas spray booster 10 is provided with holder 8, left and right sides holder 8 with welding manner and level spray booster 10 in proportion the size level that is weldingly fixed on spray on the booster.The high-voltage tube interface all is equipped with sealing ring.
Operation principle: utilize public source of the gas in the power plant as the power source of pressing the ash disposal of quick-fried formula air pulse, its operating pressure is 0.4 to 1.0Mpa.Be connected to steel cylinder Compressed Air Energy Storage 5 with pipeline, in accumulator 5 outlets the magnetic valve or the plunger valve 6 of opening and closing fast be housed, valve port is connecting explosion gas spray booster, and the spray booster is along radially on average having arranged 4 nozzles on the journey.When the air pressure in the accumulator 5 reaches design pressure, pressure gauge sensor 4 actions, accumulator 5 export department's magnetic valves 6 can move, gases at high pressure moments discharges in the blast mode, explosion wave rushes at dedusting object-rotary regenerative air preheater and hits broken deposition property black dirt, and black dirt is taken away.Because explosion wave is to be discharged by the pressure of air to form no thermal-flame.Therefore can not cause the combustion of coal ash in the rotary regenerative air preheater.
