Abstract
The utility model discloses an anticlogging coal passing pipe and an anticolgging method thereof, which solve the problems that the current coal passing pipe is easy to cause the coal clogging phenomena to influence the normal running of a boiler, even result in accidents, and cause large working strength for manually clearing clog, and the like. The utility model has simple structure and convenient use, effectively solves the phenomena that coal is clogged in the coal passing pipe, ensures the normal running of the boiler, and the like. The anticlogging coal passing pipe structurally comprises a coal passing pipe connected with a hearth, and a coal falling point fluidizer is arranged at the coal falling zone of the coal passing pipe.
Description
Technical field:
The utility model discloses a kind of anti-blocking coal sliding tube.
Background technology:
Existing CFBB does not often make coal sliding tube generation chute blockage phenomenon boiler in process treatment process often need load shedding even blowing out because of ature of coal reaches designing requirement.If deal with improperly during this time also the coking accident may take place, its result will have a strong impact on stable operation and system's steam pipe system pressure of boiler.In addition, mediation chute blockage usual way is manually to use simple tool to throw to smash, labour intensity is bigger.So far do not find that the technology that can solve the coal sliding tube chute blockage occurs.
The utility model content:
The chute blockage phenomenon easily takes place in order to solve present coal sliding tube in the purpose of this utility model exactly, influencing boiler normally moves, even cause the accident, and problems such as artificial block clearing labour intensity is big, provide a kind of have simple in structure, easy to use, can effectively solve coal sliding tube chute blockage phenomenon, guarantee the anti-blocking coal sliding tube and the anti-blocking method thereof of advantages such as the normal operation of boiler.
For achieving the above object, the utility model adopts following technical scheme:
A kind of anti-blocking coal sliding tube, it comprises the coal sliding tube that is connected with burner hearth, is provided with coal breakage point fluidizer in the coal breakage location of coal sliding tube.
Described coal breakage point fluidizer comprises a fluidisation plate that is positioned at the coal breakage zone, and the fluidisation plate is communicated with air compartment, is provided with several fluidisation apertures on the fluidisation plate.
Described coal sliding tube top is provided with flame-observing hole.
In the utility model, the coal breakage point of coal sliding tube is to have certain speed and the point that at first contacts in dropping process with the coal of quality, and the wearing and tearing of this point are maximum, the more obvious attenuate of wall thickness at this place of operation by a period of time, roughness increases to maximum, forms local dip's nest shape; In addition, (nest place, hole) was difficult for flowing in this zone when the thinner coal of granularity fell, and just produced accumulation at this place like this, just caused the generation of chute blockage in the course of time.Hence one can see that, solve the chute blockage problem just changes the problem of removing coal breakage dot product coal into, by above pipeline convey materials flow behavior is studied, removed former coal breakage district and increased a porous flat plate (pipe is an arc) for eliminating coal breakage dot product coal at this place, at the air that its bottom is established an air compartment and fed certain temperature and pressure, the chute blockage problem that makes this district keep fluidized state always, avoid long-pending coal to cause.
The beneficial effects of the utility model are:
The application of this method can effectively prevent the stopping state that coal produces in coal sliding tube, the assurance coal supply apparatus for boiler is stablized coal supply, reduces or eliminates the blockage problem of pipeline under any operating mode, and then guarantees stable operation of the boiler.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of coal breakage point fluidizer;
Fig. 3 is a fluidisation plate structure schematic diagram.
Wherein, 1. burner hearth, 2. coal sliding tube, 3. fluidisation plate, 4. fluidisation aperture, 5. air compartment, 6. flame-observing hole, 7. coal breakage zone.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, Fig. 2, Fig. 3, the method for the employing of saying so " coal breakage point fluidisation " that anti-blocking method provided by the utility model is summarized.The approach of realization the method is at first set up fluidization regions in the coal breakage zone 7 and the zone, front and back thereof of coal sliding tube 2, the foundation of this fluidisation area then is to realize by the fluidisation plate 3 that increase has several fluidisation apertures 4, one fluidized wind chamber 5 is set in the outside of this fluidization regions, and to feed pressure to air compartment 5 be the fluidization air less than 300 degrees centigrade less than 0.5mPa, temperature, by the wind-force effect coal of piling up is blown afloat, prevented the generation of chute blockage.Coal sliding tube 2 one ends are communicated with burner hearth 1, and the other end is provided with flame-observing hole 6.
Therefore for amount of labour the utility model of realizing boiler stable high yield, minimizing workman discloses a kind of coal sliding tube anti-blocking method, the improvement of internal is arranged to handling chute blockage.
