Abstract
The utility model belongs to devices for removing accumulated dust inside boilers and particularly relates to a single-tank single-jet boiler steam pulse ash removing device. A t-branch pipe is connected on a steam inlet pipe, a first branch steam pipe is connected on a connector on one side of the t-branch pipe, a first branch steam pipe outlet provided with a first steam control valve is connected with an inlet of a first steam tank, and a first nozzle is installed on an outlet pipe connected with an outlet of the first steam tank through a first steam control quick exhaust valve for controlling compressed air. A second branch steam pipe is connected on a connector on the other side of the t-branch pipe, a second branch steam pipe outlet provided with a second steam control valve is connected with an inlet of a second steam tank, and a second nozzle is installed on an outlet pipe connected with an outlet of the second steam tank through a second steam control quick exhaust valve for controlling compressed air. The single-tank single-jet boiler steam pulse ash removing device is capable of effectively removing accumulated dust in all parts of the boiler, high in dust removing capacity, free of obvious continuous noises and combustible gas, safe and reliable to use, and low in operation cost.
Description
Technical field
The utility model belongs to the device, particularly a kind of single tank single jet Boiler Steam pulse dust cleaning device of removing the boiler internal dust stratification.
Background technology
Burning in boiler coal or oil firing, can deposit a large amount of black dirts at tube surface, and after the boiler tubes superficial dust, boiler efficiency can sharply descend.Ash removal method commonly used is that hand sweeping is carried out in blowing out later, or water is rushed Xian; Use steam soot blowing when boiler operatiopn, use steam soot blowing to cause the tube surface erosive wear, reduce the service life of boiler tubes, and the maintenance load of steam sootblower is larger.The sixties in last century, Sweden starts to adopt sound wave to carry out deashing, and many boilers adopt multiple sound wave ash cleaner so far the nineties in China, this mode, have the deashing scope wide, and result of use is good, do not damage the advantages such as boiler tube, but the noise that sound wave ashing causes leaks, placed restrictions on its scope of application.The seventies former Soviet Union adopts acetylene and oxygen mix, is fired deashing, reaches northeastward the ground such as Shandong, Beijing and is promoting, the title such as be called gas impulse, shock wave, fire.Gas impulse is used the acetylene fuel gas, fires rear part residual air still in the stove internal combustion, brings hidden danger to safety in Boiler Furnace, and general recommendations is used under the flue-gas temperature condition lower than 700 ℃.
Summary of the invention
The purpose of this utility model is to provide a kind of single tank single jet Boiler Steam pulse dust cleaning device, can effectively remove the dust stratification of each several part in boiler, and deashing ability is strong, and without obvious roughness, without fuel gas, safe and reliable, operating cost is low.
The purpose of this utility model is achieved in that a kind of single tank single jet Boiler Steam pulse dust cleaning device, connecting three-way pipe on the steam steam inlet pipe, connecting the first branch trachea on the interface of three-way pipe one side, the first branch trachea outlet that the first steam control valve is installed is connecting the import of the first vapour tank, on the outlet that the first gas control rapid escape valve that the outlet of the first vapour tank is controlled by compressed air connects, the first spout is installed; Connecting the second branch trachea on the interface of three-way pipe opposite side, the second branch trachea outlet that the second steam control valve is installed is connecting the import of the second vapour tank, on the outlet that the second gas control rapid escape valve that the outlet of the second vapour tank is controlled by compressed air connects, the second spout is installed.
The utility model steam pulse soot blower technology, can produce fully and the basis of impulse wave, acoustic energy grade and the high velocity air of gas impulse shock-wave ash blowing technology same effect on effectively overcome its major defect, owing to not adopting fuel gas, it is the unconfined any position that is installed on boiler in the least, the potential safety hazard because using combustion gas to bring, do not control and simply need not change source of the gas.Simultaneously because this system architecture and control principle that blows gray technology is very similar with former common steam soot blower and acoustic wave ash ejector, therefore will be very convenient for the transformation of old boiler soot blower system, investment cost and operating cost expense all are significantly less than the gas impulse shock-wave ash blowing.The steam pulse soot blower has very strong impulsive force, and there is no the limitation of combustion gas, can also be applied to the block clearing of Slag Cooler for Circulation Fluidized Bed Boiler.Experiment shows, for the slag of caking state, can under the impact of this system, pulverize, and has solved the blockage problem of Slag Cooler for Circulation Fluidized Bed Boiler.
The utility model major parameter
Operating distance: 7--9M interpulse period: 1S transient peak sound pressure level L: >=160dB steam pressure: 1.6-2.5Mpa
Single steam consumption quantity :≤0.5 M3/ time
To removing ash of boiler, according to dust stratification order of severity difference, usually deashing can improve 0.5-1.5% boiler efficiency, so the ash removing equipment of the station boiler very important equipment that is power plant, its operation conditions and result of use are directly connected to the economic benefit in power plant.
The utility model has following effect:
1。Can effectively remove boiler each several part dust stratification, deashing ability increases 2--3 doubly than the air pulse deashing device.The basic acoustic wave soot blower ash-removal effect that substitutes.Change jet expansion shape and direction, can remove boiler different parts dust stratification.
2。Can be because of using deashing device, the damage boiler tubes.Substituted the original steam soot blower.
3。Adopt the steam pulse ash remover, without obvious continuing noise, overcome the excessive shortcoming of acoustic wave soot blower noise.
4. adopt the steam pulse ash remover, without fuel gas, can not bring implosion to threaten to safe operation of the boiler.
The utility model has been realized the dust stratification of each several part in effect ground removing boiler, and deashing ability is strong, and nothing is roughness obviously, and without fuel gas, safe and reliable, operating cost is low.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
