Description
Technical field
The utility model is related to a kind of anti-blocking control systems of coal spout.
Background technology
An important factor for causing coal pipe coal blockage is coal attached collection on tube wall.And the position for easy ting produce attached collection is kept off in threeway
The junction of plate and oblique siphunculus, and the tiltedly dead angle of siphunculus both sides bottom surface.For by material coal.Be easy attached collection it is main because
Element is water and granularity.The small dry coal viscosity of aqueous component is small, it is not easy to attached collection.And aqueous component it is big conveying inertia it is big, stream
Dynamic property is strong, not easy to knot groups, and conglomeration is easy when the water content of coal is in 10%-15%.And the coal of this humidity is easy by rain
It is generated in the case of leaching.Therefore, for the southern power plant in rainy season for coal handling system, rainy season defeated coal chute blockage is just natural
And the right big factor for becoming influence production efficiency.
The particle of coal is also the reason of generating blocking.From empirically knowing that lumped coal is not easy to block, because when its conveying
Inertia is big, and momentum is big, and granularity has the coal of certain humidity to be easier, in the attached collection conglomeration of tube wall, to reduce coal and pass through in 5-50um
The section of pipeline generates blocking.
Chinese patent 201020206137.X discloses a kind of anti-blocking device of coal chute, including jet chimney, wherein steam
Pipe end is equipped with nozzle, and jet chimney is equipped with pressure reducing valve, pressure gauge and shut-off valve, and jet chimney is equipped with a branched pipe
Road, lateral are equipped with drain valve.By jet chimney be connected to filtering superheater hydrophobic valve on, end by nozzle with
Coal spout connects；Heating coil is carried out in use, first opening drain valve, is then shut off drain valve, shut-off valve progress steam is opened and blows
It sweeps, ensures the unimpeded of boiler coal feeding, prevent coal breakage blockage；Original state is then returned to after purging, waits for next round
Secondary purging.
Chinese patent 201220143896.5 discloses a kind of anti-blocking boiler coal chute, including upper side port connection feeder and
The coal spout of lower mouth connection boiler, device reciprocal catch bar in place's suitable for reading of coal spout, the driving pawl of reciprocal catch bar lower part stretch into
In coal spout, gives coal one power when coal spout blocks, coal is made to fall to burner hearth.
The existing scheme of coal breakage blockage is prevented to be primarily present following defect：
1, coal breakage blockage is often manually cleared up, time-consuming, labor intensity is big.
2, high molecular abrasion-proof or stainless steel plate lining are laid in the positions such as oblique siphunculus, three-way baffle plate inner wall, it is attached to reduce coal dust
Collection bonds.But expense is too high, replaces difficult, pipeline flow section reduction.
3, electric motor of shaker is filled near three-way baffle plate and inclined tube or straight tube outer wall, coal vibration is gone down by mechanical oscillation,
But since its several component is fixedly connected, electric motor of shaker can only rapping pipeline one side, the amplitude of rapping and involve
Depth is limited, the effect unobvious and long-term vibration of vibrating motor is easily damaged and increases maintenance capacity to maintenance personal.
Though 4, coal chute road makes the reduction of stainless steel viscosity into but improvement project amount is big, costly.
Therefore, how a kind of operation, easy to maintenance is provided, advantageously reduces and shuts down required number and time, to carry
The anti-blocking control system of coal spout of high efficiency, becomes problem to be solved in the industry.
