Abstract
The invention relates to a method for removing ash from a boiler, particularly method for removing ash from a cement kiln exhaust-heat boiler, and specifically a method for removing ash through shooting steel balls by a steel ball shooting gun to vibrate and hit a target on the heating surface of the boiler to vibrate the heating surface of the boiler. The method comprises the following steps: fixing the target on a tube wall of the heating surface adhered with ash of the boiler; and shooting the steel balls to the target by the steel ball shooting gun to vibrate the target, enabling the ash on the heating surface of the boiler to fall off by the vibration generated from the vibration and hit of the steel balls to the target through the heating surface of the boiler. According to the method, the heating surface of the boiler vibrates omnidirectionally, and the aim of removing ash from all regions of the heating surface of the boiler is achieved.
Description
Technical field
The present invention relates to a kind of particularly a kind of ash removal method of kiln heat recovery boiler of boiler that is used for, specifically be meant a kind of steel ball ejecting gun emission steel ball that passes through, the target on the rapping boiler heating surface makes the vibrative ash removal method of boiler heating surface.
Background technology
The dust of boiler heating surface has reduced the heat transfer coefficient of boiler heating surface, influences the heat transfer property of boiler.The dust of serious boiler heating surface can cause burning or heat transfer deterioration, even boiler tube booster and boiler explosion accident occur.
Utilize the ash removal method of common mechanical vibrator, the direction and the zone of rapping are restricted, and occur the phenomenon at deashing dead angle easily.
The ash removal method of steel ball is sowed at the boiler top, utilizes the gravity rapping boiler heat-transfer face of steel ball itself, and the dynamics of rapping is unique, and the direction of rapping is the direction of gravity basically, is unfavorable for the comprehensive deashing of boiler heating surface.
Summary of the invention
The technical problem that the present invention will solve is; Deficiency to the prior art existence; Design a kind of method,, select steel ball launch point and target according to the deployment scenarios of boiler heating surface through the comprehensive vibration boiler heating surface of steel ball ejecting gun emission steel ball; Make boiler heating surface produce vibration, reach the purpose of deashing.
Technical scheme of the present invention is, a kind of ash removal method through the comprehensive vibration boiler heating surface of emission steel ball is characterized in that this method is: adhere on the tube wall of heating surface of dust fixedly target at boiler; To target emission steel ball rapping target, by the vibration that said steel ball rapping target produces the dust on the boiler heating surface is come off with the steel ball ejecting gun through boiler heating surface.
Below the present invention is further described.
Fixing target respectively on the different azimuth of a heating surface of boiler.
At fixing jointly at least one target of a plurality of heating surfaces of boiler, a plurality of heating surfaces are vibrated simultaneously.
The steel ball ejecting gun can angle changing and position, can be to the target emission steel ball of different azimuth.
Steel ball is reusable.
Steel ball according to the invention does not directly contact with boiler heating surface, on the tube wall of heating surface, is welded with target, is steel ball rapping position, avoids occurring the direct rapping tube wall of steel ball and causes the distortion of boiler heating surface and the situation that the boiler heating surface tube wall breaks; Through multi-faceted steel ball target is set, realize comprehensive vibration to boiler heating surface, reach the purpose of comprehensive boiler heating surface deashing; The layout that adapts to boiler heating surface needs two steel ball ejecting guns even racemosus steel ball ejecting gun at least, satisfies the function of multi-faceted vibration dust-cleaning.
The steel ball that is used for vibration dust-cleaning after the action of completion rapping target, falls into the ashcan of boiler or the steel ball gathering-device of boiler, is filled into the steel ball ejecting gun through artificial filling or machinery, realizes the recycle of steel ball.
Know that by above the present invention has comprehensive vibration boiler heating surface for the ash removal method through emission steel ball vibration boiler heating surface, reaches the purpose of the region-wide deashing of boiler heating surface.
Description of drawings
Fig. 1 is the system schematic of an embodiment of the present invention;
In the drawings:
1-steel ball ejecting gun, 2-steel ball, 3-target, 4-boiler heating surface.
The specific embodiment
As shown in Figure 1, the ash removal method of emission steel ball according to the invention vibration boiler tube, this method is: adhere on the tube wall of heating surface 4 of dust fixedly target 3 at boiler; To target 3 emission steel balls 2 rapping targets 3, by the vibration that said steel ball 2 rapping targets 3 produce the dust on the boiler heating surface 4 is come off with steel ball ejecting gun 1 through boiler heating surface 4.
Steel ball in the steel ball rifle 1 places the funneling magazine of body of a gun top, with CO
2Or other Compressed Gas is power, utilizes the power that hitting hangs down produces steel ball under impacting with high pressure to produce fire effect.Adopt spring piston formula, air pressing type or air bottle type radiation pattern, all can launch steel ball.The effect of target 3 is protection boiler heating surfaces 4, and the momentum of conversion steel ball 2 is the vibration force of boiler heating surface 4.
On place's boiler heating surface 4, can arrange a plurality of targets 3, satisfy the rapping requirement of the different parts of boiler heating surface 4; Many places boiler heating surface 4 also can be arranged at least one target 3 jointly, and the many places heating surface is vibrated simultaneously.
