Description
Technical field
The present invention relates to a kind of coal dust feeding system with swinging conveying pipe, be particularly well-suited to high-efficiency pulverized coal industry pot
Stove.
Background technology
German Industrial pulverized-coal fired boiler, with its safety, the feature of environmental protection (exhaust emissions and generating plant pulverized coal boiler, gas fired-boiler phase
When), advanced (automatic measuring and controlling, teletransmission manipulation, unmanned), economy (efficiency of combustion more than 98%, boiler thermal output up to
More than 92%) can be, the succedaneum of oil and gas as clean energy resource.The small and medium-sized industrial coal powder boilers of China uses for reference Germany
The technology of industrial coal powder boiler and theory, last 10 years, has in the technology such as coal dust tower of key core, feed, combustion system
Broken through.
Chinese patent literature CN201458346U discloses a kind of pulse-free coal powder supply device, can effectively solve coal dust and exist
The phenomenon of compensation is piled up, blocks and carried to coal chute in road.But also bring another one problem, due to helical blade
And cannot avoid between duff pipe there is gap, owing to spiral transferring tube cell bottom is provided with coal dust mixing injector, at pulverized coal flow
Threading a pipe interior formation negative pressure, it is difficult to control charging rate, excess coal dust is poured into burner hearth and is formed detonation.
Summary of the invention
The technical problem to be solved provides a kind of for above-mentioned prior art and carries pipe with swinging
Feeding system, it may ensure that the stable material-supplying of coal dust.
The present invention solves the technical scheme that the problems referred to above are used: a kind of feeding system with swinging conveying pipe,
It includes that feed bin, the first horizontal tube and the second horizontal tube being sequentially arranged from top to bottom, described first horizontal tube left end are provided with
Roots blower, is connected by bridge piece between described first horizontal tube right-hand member and the second horizontal tube right-hand member, described first water
It is provided with Venturi in flat pipe, is connected by material blanking tube between described bin bottom and Venturi.
Described feeding system also includes that spiral conveying pipeline, described spiral conveying pipeline are provided with charging near the upside of one end
Mouthful, the downside of the other end is provided with discharging opening, described bin bottom is connected with charging aperture, described discharging opening and material blanking tube
It is connected.
Described material blanking tube top half is vertical section, and the latter half is tilting section, the tilting section of described material blanking tube and level
The angle of line is 40 ° ~ 80 °.
Being provided with blowing pipe on the downside of described spiral conveying pipeline, the position of described blowing pipe is corresponding with the position of charging aperture.
Being provided with respiratory organ on the upside of described spiral conveying pipeline, the position of described respiratory organ is corresponding with the position of discharging opening.
Compared with prior art, it is an advantage of the current invention that:
1, coal dust blanking is smooth and easy, stable, without blocking, without piling up；
2, coal dust feed is stable, controlled, will not cause detonation because pouring into burner for a large amount of coal dust of local decompression in powder pipeline.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As it is shown in figure 1, a kind of feeding system with swinging conveying pipe in the present embodiment, it includes depending on from top to bottom
Feed bin 6, first horizontal tube 2 of secondary layout and the second horizontal tube 3, described first horizontal tube 2 left end is provided with roots blower 1, institute
State and be connected by bridge piece 5 between the first horizontal tube 2 right-hand member and the second horizontal tube 3 right-hand member, described second horizontal tube 3 left end
Connect pipeline and access boiler-burner, in described first horizontal tube 2, be provided with Venturi 4, with literary composition mound bottom described feed bin 6
In be connected by material blanking tube 9 between device 4, roots blower wind out forms high-speed jet through Venturi, carries
Form wind powder mixture after the coal dust that material pipe falls, enter bridge piece, wind powder gas after reduction of speed, current-sharing after 180 ° turn to
Stream, enters boiler-burner through conveyance conduit.
Described material blanking tube 9 top half is vertical section, and the latter half is tilting section, the tilting section of described material blanking tube 9 and water
The angle of horizontal line is 40 ° ~ 80 °, and this angle is more than the angle of repose of coal dust；
The coal dust of material blanking tube 9 lower port falls due to deadweight, and the Venturi 4 of its underpart produces ejector action simultaneously, and fall ash
Producing negative pressure acceleration coal dust in bucket to flow downward, the wind that coal dust carries with roots blower forms wind powder mixture through literary composition after mixing
Current-sharing through bridge piece 5 after device 4 in mound, slow down after enter boiler；Bridge piece 5 is 180 ° of bend pipes, and it can buffer
Wind powder mixture after Venturi 4, prevents wind powder mixture from entering boiler with too high speed；
Described feeding system also includes that spiral conveying pipeline 7, described spiral conveying pipeline 7 are provided with charging aperture near the upside of one end,
The downside of the other end is provided with discharging opening, is connected with charging aperture bottom described feed bin 6, described discharging opening and material blanking tube 9
It is connected；
Being provided with blowing pipe 10 on the downside of described spiral conveying pipeline 7, the position of described blowing pipe 10 is corresponding with the position of charging aperture,
Ensure that discharging is not lumpd, do not block；
Being provided with respiratory organ 8 on the upside of described spiral conveying pipeline 7, the position of described respiratory organ 8 is corresponding with the position of discharging opening, can
Make the pressure in spiral conveying pipeline keep basically identical with external atmosphere pressure, thus realize stable material-supplying.
In addition to the implementation, present invention additionally comprises other embodiments, all employing equivalents or equivalence to replace
The technical scheme that mode is formed, all should fall within the scope of the hereto appended claims.
