Abstract
A soot blower using steel beads for boiler is composed of bead accepter and its handle, locking part and fixed supporter. Said head accepter plays the role of temporarily storing the steel beads dropped irregularly when boiler tail is heated and soot is not blowed to prevent the steel beads from being directly dropped to bottom of collector, where they are rusted together into conglomeration to block the sprayer. During soot blowing, the conglomeration of steel beads are poured to grate or sieve plate with higher hardness and rigidity to break it under the action of impact energy, so not blocking the sprayer.
Description
The present invention is used for the steel ball soot blower of boiler steel balls ash blowing device especially for oil burning boiler.
At present widely used steel ball blows gray technology and sees U.S. Pat-2665118 and US-3291197 the earliest in the oil burning boiler.At the viscous ash deposit that oil burning boiler tail flue gas passage exists, use steel ball to blow ash and can obtain better effect." oil burning boiler combustion apparatus and operation " book of hydraulic and electric engineering publishing house publication in 1976 has been done detailed description to the design and the maintenance of steel ball soot blower, the steel ball soot blower of describing in the book is that Chu Zhudou is arranged on outside the boiler smoke passage, utilizes compressed air or steam to carry steel ball by injector.Mostly existing steel ball soot blower is described in " oil burning boiler combustion apparatus and operation ", this existing boiler steel balls ash blowing device is difficult to realize automated job, steel ball blows ash and is difficult to realize that the reason of automation is that the easy rust joint of steel ball in the Chu Zhudou becomes piece, stop up the injector of carrying steel ball, cause and blow the ash interruption.The steel ball caked reason of becoming rusty is to meet water attached to the acid ash on steel ball surface to generate dilute sulfuric acid corrosion steel ball.Its base reason is: be inclusive with SO in the flue gas attached to steel ball surface cigarette ash
3Gas combines the sulfuric acid vapor of generation with the water vapour in the flue gas, sulfuric acid vapor dewfall in being lower than the Chu Zhudou of flue gas acid dew point generates H
2SO
4(cigarette ash of this moment claims the acid ash), H
2SO
4Absorb the moisture in the atmosphere again, form dilute sulfuric acid, under the corrosiveness of dilute sulfuric acid, the steel ball rust joint becomes agglomerate, and it is to cause the steel ball caked main cause of becoming rusty that the acid ash absorbs dilute sulfuric acid corrosion that the moisture in the atmosphere forms.In addition, a spot of economizer leakage water, operation mistiming entry such as sanitization for outdoor boiler, also have the sleet water of going into of pouring, can both generate dilute sulfuric acid corrosion steel ball with the reaction of acid ash.In Japan Patent JP-58-217112 (A), a kind of cement plant waste heat boiler slag-blowing equipmemt and method are disclosed, this method is to replace steel ball that the heating surface of heat exchanger is blown ash with granular material, these granular materials are made the raw material of cement in company with the black dirt of removing conduct together, obviously, in this soot blower, if adopt steel ball to replace granular material, steel ball still can become piece by rust joint under the effect of acid ash, stop up the injector of carrying steel ball.Chinese patent (application number) 88102800.2 discloses a kind of steel ball caked method of becoming rusty that prevents in Chu Zhudou, its method is that Chu Zhudou is arranged at temperature in the space more than the flue gas acid dew point, and the easiest method is the porch that storage pearl bucket is arranged on boiler back end ductwork.This design has solved the steel ball caked problem of becoming rusty in Chu Zhudou, but blow between the grey operation at twice, still have a spot of steel ball can fall into gatherer aperiodically, these steel balls that irregularly fall are attached with the acid ash equally, they become piece at the injector place rust joint that is lower than the gatherer bottom below the flue gas acid dew point, stop up to carry the injector of steel ball again, cause and blow grey operation next time and can not start.The reason that a small amount of steel ball irregularly falls is: when blowing grey operation last time, some steel ball is trapped on the back-end surfaces.The position that can be detained steel ball on the heating surface has: the upper surface that supports the girder steel (frame) of boiler tail heated element (economizer, air preheater); The upper surface of back-end surfaces furnace wall (skin) high spot; Stretch into the upper surface of the rectangle manhole of furnace wall (skin); Economizer two horizontal tube outer walls distance is less than the diameter of the steel ball place.Wherein more less than the steel ball that the diameter of the steel ball place is detained with economizer two horizontal tube outer walls distance, its base reason is: the thermal deformation of boiler economizer in service has changed the distance (and the change of these distances is to destroy the boiler smoke dynamic equilibrium of boiler) between the outer wall of economizer tube, make distance between some economizer tube outer wall less than the diameter of steel ball, cause steel ball to be detained.The steel ball that above-mentioned position is detained can't fall when blowing the grey end of job simultaneously, but along with the vibrations not timing of boiler unit in service is fallen.The steel ball that not timing is fallen also has: in the pearl ash separator because the retardance of dust stratification and blew the steel ball that grey end of job fashion does not fall in last time; In the ash bucket because the retardance of dust stratification and blew the steel ball that grey end of job fashion does not fall in last time.
Task of the present invention is: propose a kind of design, to blow the steel ball and the gatherer that irregularly fall after the grey end of job isolates, stop the steel ball that irregularly falls directly to fall into the injector place of gatherer bottom, thereby prevented the obstruction of injector, and then realized that boiler steel balls blows the automated job of ash.
