Description
Technical field
The utility model belongs to field of dust, particularly relates to a kind of boiler online ash removal device.
Background technology
Convection section finned tube dust stratification can directly cause exhaust gas temperature to raise in the boiler, 10～15 ℃ of the warm every risings of discharging fume, boiler thermal output descends 1%, behind the each thoroughly deashing of boiler, general exhaust gas temperature can drop to below 200 ℃, in boiler operatiopn as fuel, atomizing, the air distribution imbalance can cause boiler " over-emitting black exhaust " to aggravate the boiler cigarette temperature rate of climb, boiler convection section deashing generally manually carries out under blowing out cold conditions state, after opening stove, the cigarette temperature rises day by day and can't the on-line implement deashing, can cause waste of fuel, oily vapour unit consumption rises, so need a kind of device that can online ash removal.
Present online ash removal device is divided into three kinds, steam dust remover, acoustic wave soot blower and gas shock-wave dust remover.
Steam dust remover operation principle is to utilize steam, superheated steam with certain pressure to be blowing medium, the tubulose of the long number rice of, rotation scalable by purges rifle and puts in the middle of the convection section finned tube, directly purges dust stratification on the heating surface with steam or superheated steam.The major defect of this kind pattern dust remover is that Mechanical Reliability is poor, deashing just has a large amount of mechanical parts wearing and tearing after often experiencing a period of time operation, damages, failure mode is generally stuck, bite, the result is not that dust remover can not cause boiler thermal output to descend by bringing normally into operation, be exactly because purge with the high steam long-time continuous, high steam carries dust erosive wear heating surface tube wall, cause the boiler pipe explosion accident, and because this type dust remover is to utilize high steam to purge working method continuously, the energy consumption of equipment itself is very big.
Acoustic wave soot blower refers to utilize the effect of sound field energy, removes the method for boiler heat-exchanger superficial dust and coking, and this kind dust remover acoustic energy of maximum at present only can reach 150 decibels, and the energy intensity deficiency is very limited to the scavenging action of dust stratification.
The gas shock-wave dust remover mainly be with fuel gas (acetylene, natural gas, oil gas is useful fuel-oil atmozation also) with air with certain proportion in the gaseous mixture in-tank mixing, after lighting a fire, produce detonation, impact the mouth of pipe at front end and produce shock wave, utilize shock wave that heating surface is purged.This dust remover because of working media be fuel gas, and the interior cigarette Wen Wendu of each section flue is very high in the boiler, fuel gas enters burner hearth without igniting or flue can cause tempering detonation or cause the bursting of boilers, so can only be used for low-temperature zone, range of application has significant limitation.
Usually the spout part in above-mentioned these deashing devices all is to be fixedly mounted on the furnace wall, and each shock wave ejection all can produce certain concussion to the furnace wall, and can cause the loosening of coupling part, has influenced the reliability of equipment.
Summary of the invention
Technical problem to be solved in the utility model provides the routed online impact deashing device of formula boiler of a kind of contracting; the routed mechanism of contracting is housed on the spout of this device; each shock wave ejection rear jet can contract backward and move back, and then by the back-moving spring return, has improved reliability greatly.
A kind of contracting online impact deashing device of formula boiler of bursting, comprise compressed air reservoir, shock wave generator, control valve and shock wave injection apparatus, the air inlet pipe of described shock wave generator is communicated with compressed air reservoir, the shock wave spout of shock wave generator is by shock wave pipeline connection shock wave injection apparatus, control valve is housed on the shock wave generator, the control end of control valve is connected with cyclelog, described shock wave injection apparatus is fixedly mounted on the furnace wall, the spout of shock wave injection apparatus passes the furnace wall, the shock wave injection apparatus is provided with the routed fairlead of the contracting that matches with spout, is provided with the back-moving spring that links to each other with spout in the routed fairlead of described contracting.
Described control valve is single control magnetic valve.
Described shock wave injection apparatus is pneumatic stepping rotary nozzle, and the control mouth of described pneumatic stepping rotary nozzle is communicated with shock wave generator by wireway.
Be provided with bearing between described spout and the furnace wall.
Described pneumatic stepping rotary nozzle single step stepping angle is 45 °.
The axis of the spout of described shock wave generator and horizontal angle are 15 °～30 °.
The routed mechanism of contracting is housed on the spout of the routed online impact deashing device of formula boiler of the utility model contracting; each shock wave ejection rear jet can contract backward and move back; and then by the back-moving spring return; greatly reduce impact and concussion to the furnace wall; can not influence being connected between shock wave injection apparatus and the furnace wall yet, improve reliability greatly.
