Description
Technical field
The present invention relates to a kind of positive pressure steel ball gray-blowing system, specifically be used to remove the dust stratification on the boiler tail vertical well gas flue internal heating surface.
Background technology
In prior art, at present, steel ball gray-blowing system is contained in the steel ball in the Chu Zhudou, by the suction of steam air ejector, collects in the gatherer through supplying the pearl device and rising the pearl pipe.Be furnished with the blind window grid in the gatherer, gas enters atmosphere by exhaust tube; Steel ball enters little bucket through the top flapper, enters buffer again, drops at last on the semi-round ball of diffuser, sows on heating surface.Steel ball that deashing is later and ash enter ash bucket together, and most of thin ash is taken away by flue gas, and cinder and steel ball fall into separator; The formed air-flow of gas in the separator of bleeding is drawn cinder and is entered exhanst gas outlet by the flying dust fairlead, the steel ball of cleaning falls into Chu Zhudou through the bottom flapper, through for the pearl device with rises pearl and manage, so recycles again.
Original product adopts negative pressure system, adopts steam-sprayed air ejector, utilizes pressure to be generally 1.3MPa, temperature is that 260～320 ℃ of steam are the vapour source; Its parameter is than low many of the steam parameter of electricity generation boiler, so Boiler Steam could be used after need reducing pressure; Therefore can cause the waste energy.Adopt the negative pressure transportation steel ball, rely on steel ball deadweight ash disposal, effect is not so good.
Original product vapour injection formula air ejector is arranged on the furnace roof, link to each other with gatherer through exhaust tube, so the gatherer domestic demand is furnished with the blind window grid, to prevent that steel ball from entering air ejector and discharging; Flying dust fairlead on top flapper and little bucket, the separator also need be set in addition and have the twice gate for the pearl device.This kind system architecture complexity, easily worn part is more, in servicely breaks down easily, and maintenance capacity is big.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of positive pressure steel ball gray-blowing system is provided, the energy energy savings, easy to operate; Easily worn part is less, and in service being difficult for breaks down, and the operating maintenance amount is little.
Main solution of the present invention is achieved in that
The present invention mainly adopts collector arrangements above furnace roof, and tube connector one end connects gatherer, and the other end is connected with buffer, and diffuser is installed in the buffer lower end; Ash bucket is arranged on the below of body of heater, and the ash bucket below connects separator; The adjustment doors upper end connects separator, and the lower end connects Chu Zhudou; The Zhu Men that falls is connected Chu Zhu bucket lower end; Feature is in the pearl student side that falls the steel ball injector to be set, and rises pearl Guan Yiduan and connects the steel ball injector, and the other end is connected with gatherer.
Described steel ball injector is provided with the injector compressed air inlet.Described separator is provided with the separator compressed air inlet.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable; The energy energy savings, easy to operate; Easily worn part is less, and in service being difficult for breaks down, and the operating maintenance amount is little.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing of the present invention its enforcement is further described:
The present invention is mainly by gatherer 1, furnace roof 2, tube connector 3, buffer 4, diffuser 5, heating surface 6, ash bucket 7, separator 8, separator compressed air inlet 9, adjustment doors 10, Chu Zhu bucket 11, the pearl door 12 that falls, steel ball injector 13, injector compressed air inlet 14, exhanst gas outlet 15 and rises pearl and manage 16 etc. and form.
As shown in Figure 1, the present invention adopts gatherer 1 to be arranged in furnace roof 2 tops, and tube connector 3 one ends connect gatherer 1, and the other end is connected with buffer 4, and diffuser 5 is installed in buffer 4 lower ends; Ash bucket 7 is arranged on the below of body of heater, and ash bucket 7 lower ends connect separator 8, and separator 8 is provided with separator compressed air inlet 9; Adjustment doors 10 upper ends connect separator 8, and the lower end connects storage pearl bucket 11; The pearl door 12 that falls is connected Chu Zhu 11 lower ends of struggling against; In Luo Zhumen 12 lower ends steel ball injector 13 is set; On steel ball injector 13, be provided with injector compressed air inlet 14; Rise pearl and manage 16 1 ends connection steel ball injector 13, the other end is connected with gatherer 1; On body of heater, be provided with exhanst gas outlet 15.
Operation principle of the present invention:
The present invention is by the steel ball that is contained in the Chu Zhu bucket 11, pearl door 12 enters steel ball injector 13 through falling, under the compressed-air actuated effect of injector compressed air inlet 14, enter and rise pearl pipe 16 and enter in the gatherer 1, enter buffer 4 through tube connector 3 then, under compressed-air actuated conveying, steel ball quickens to drop on the semi-round ball of diffuser 5 down, sows on heating surface 6 at last.Steel ball that deashing is later and ash enter ash bucket 7 together, and most of thin ash is taken away by flue gas, and cinder and steel ball fall into separator 8; Under the compressed-air actuated effect of separator compressed air inlet 9 cinder is separated with steel ball, cinder enters exhanst gas outlet 15, and the steel ball of cleaning falls into Chu Zhu bucket 11 through adjustment doors 10, enters steel ball injector 13 through the pearl door 12 that falls again, so recycles.
The present invention adopts the compressed air positive pressure system, adopts the venturi formula steel ball injector 13 that is arranged in pearl door 12 following aditus laryngis adjustable size, utilizes pressure to be about 0.5MPa compressed air delivery steel ball.And under compressed-air actuated conveying, steel ball quickens to drop on the semi-round ball of diffuser 5 down, sows on heating surface 6, reaches the purpose of removing dust stratification.
The present invention adopts positive pressure system, and the separator 8 of ash bucket 7 bottoms utilizes the compressed air of separator compressed air inlet 9 that cinder is separated with steel ball; Adjustment doors 10 below the separator 8 can allow steel ball fall, and prevents that simultaneously the compressed air of injector compressed air inlet 14 from bleeding.
