Abstract
The utility model belongs to devices used for cleaning dust inside a boiler, and particularly relates to a one-pot-multi-jet-spray type boiler steam pulsating dust-cleaning device. According to the one-pot-multi-jet-spray type boiler steam pulsating dust-cleaning device, a steam inlet pipe provided with a steam control valve is connected with an inlet of a sealed steam pot, a three-way pipe is connected with an outlet of the steam pot, a first air control fast air exhausting valve which is controlled through compressed air and arranged on a connection opening in one side of the three-way pipe is connected with an outlet pipe, a first spraying opening is formed in the outlet pipe, a second air control fast air exhausting valve which is controlled by compressed air and arranged on a connection opening in the other side of the three-way pipe is connected with another outlet pipe and a second spraying opening is formed on the outlet pipe. The-one-pot-multi-jet-spray type boiler steam pulsating dust-cleaning device is capable of effectively cleaning dust on each part in the boiler, high in dust-cleaning capacity, free of obvious continuous noise, safe and reliable in usage due to the fact that no flammable gas is used, and low in running cost.
Description
Technical field
The utility model belongs to the device, particularly an a kind of tank multi-port Boiler Steam pulse dust cleaning device of removing the inner dust stratification of pot.
Background technology
Burning in boiler coal or oil firing can at tube surface, deposit a large amount of black dirts, the thermal conductivity factor of these black dirts is extremely low, and its thermal conductivity factor is lower 400-1000 times than the thermal conductivity factor of steel pipe, therefore, after the boiler tubes superficial dust, boiler efficiency sharply descends, and can make burning coal or oil firing amount sharply increase; When dust stratification thickness was 0.8mm, the heat transfer loss can increase by 9.5%, and when dust stratification thickness was 3.2mm, the heat transfer loss can increase by 45.3%.So since using boiler, just sought the method for removing surperficial black dirt always.
In decades, ash removal method commonly used is that hand sweeping is carried out later in blowing out, or water rushes Xian or 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 begins to adopt sound wave to carry out deashing.China nineties, many boilers adopted multiple sound wave ash cleaner so far, and this mode has the deashing scope wide, and result of use is good, does not damage the advantages such as boiler tube, but the noise that sound wave ashing causes leaks, and had placed restrictions on its scope of application.The seventies former Soviet Union adopts acetylene and oxygen mix, fires 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 uses the acetylene fuel gas, fires rear part residual air still in the stove internal combustion, gives in Boiler Furnace and brings hidden danger safely, and general recommendations is used under lower than the flue-gas temperature condition of 700 ℃.
Summary of the invention
The purpose of this utility model is to provide an a kind of tank multi-port 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, safe and reliable without fuel gas, operating cost is low.
The purpose of this utility model is achieved in that an a kind of tank multi-port Boiler Steam pulse dust cleaning device, connecting the steam inlet pipe that steam control valve is installed in its import of vapor can of sealing, connecting three-way pipe in the vapor can outlet, the first gas control rapid escape valve of controlling by compressed air on the interface of three-way pipe one side is connecting outlet, the first spout is installed on outlet, the second gas control rapid escape valve of controlling by compressed air on the interface of three-way pipe opposite side is connecting another outlet, and the second spout is installed on another outlet.
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 of not bringing because of the use combustion gas, controlling simply need not exchange gas source.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, can pulverize under the impact of this system for the slag of caking state, 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, different according to the dust stratification order of severity, deashing can improve 0.5-1.5% boiler efficiency usually, so the ash removing equipment of the station boiler very important equipment that is the 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 realized effectively removing the dust stratification of each several part in boiler, and deashing ability is strong, and without obvious roughness, safe and reliable without fuel gas, operating cost is low.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing, and Fig. 1 is the utility model structural representation.
