Description
Technical field
The present invention relates to the anti-block apparatus of boiler ash handing pipeline.
Background technique
General fluidized-bed combustion boiler is all pressurized seal pneumatic conveying, and ash enters storehouse pump and passes through the mixed pusher of compressed air
It send to grey library, just ash and compressed air mixture homogeneity are poor when discharging, and the density of front end ash is very high, so strong in storehouse pressure
Pressure material will form high speed rotation, at this point, high-speed rotating ash and the small density of tube wall frictional force are also small, but pipeline is too long or curved
Can be offset in the case that head is more can rotation to increase density and frictional force again, become ash directly to push so ash pipe when defeated ash
It can beat.It will affect ash particle gaseous volatilization there are also grey temperature is too low, air moisture condensation etc. can all reduce the activity of ash, easily
Plugging occurs.
Coal-burning boiler at runtime, can generate a large amount of fine ash, in order to guarantee that boiler operates normally, need fine ash is continuous
Discharge boiler, existing ash pipeline is since distance is too long, and elbow is relatively more, when opening furnace ash temperature is too low and storehouse pump into
It will appear plugging when discharge valve failure, plugging finishing time is long, and the installation of former pipeline is blown stifled and jarring machine along journey and do not had
Effect well, needs manually to beat along pipeline or could dredge pipeline to idle discharge ash, take time and effort, and can also seriously affect
Surrounding enviroment.

By using above-mentioned technical proposal, the control solenoid valve of whirlwind valve is opened before when storehouse, pump outlet valve is opened, whirlwind valve
Entire pipeline forms negative pressure after opening, and compressed air enters valve body, and enters valve pipe from the inclined hole on valve pipe, will lack along journey power
The ash of mistake rotates again, increases the mobility of ash after wind and ash contact and reduces the frictional force and density of ash and tube wall, thus not
It is easy blocking.
Preferably, the inclined hole is obliquely installed towards the direction Hui Ku, and the inclined hole set along valve pipe axial rings it is multiple.
By using above-mentioned technical proposal, inclined hole has guiding role, air is made to enter valve pipe along the unwrapping wire of inclined hole,
Vortex is formed in valve pipe, and ash is rotated again and continues to push.
Preferably, the valve pipe is equipped with eight inclined holes.
By using above-mentioned technical proposal, the number of inclined hole can be arranged according to demand, meet the needs of different application.
Preferably, impact tube is connected on the punching press mouth, the impact tube is equipped with solenoid valve.
By using above-mentioned technical proposal, stamping equipment can be connected to by impact tube, meet the punching press of different pressures
Demand, and solenoid valve is provided on impact tube, flexible adjustment is easy to control, and use is safe.
Preferably, the ash handing pipeline is equipped with jarring machine.
By using above-mentioned technical proposal, when starting shock machine, jarring machine vibration will drive ash handing pipeline bounce, keep ash outstanding
Sky reduces defeated grey resistance in ash handing pipeline, reduces ash deposition when defeated grey on ash handing pipeline.
Preferably, the ash handing pipeline is equipped with air blower.
By using above-mentioned technical proposal, the setting of air blower then can further improve the gambling plug phenomenon of ash handing pipeline,
Starting air blower supports ash along claiming to blow, and defeated ash is more efficient.
In conclusion advantages of the present invention:
1. whirlwind valve is arranged on ash handing pipeline, the control solenoid valve of whirlwind valve is opened before when storehouse, pump outlet valve is opened, rotation
Air-valve entire pipeline formation negative pressure after opening, compressed air enters valve body, and enters valve pipe from the inclined hole on valve pipe, will move along journey
The ash of power missing rotates again, increases the mobility of ash after wind and ash contact and reduces the frictional force and density of ash and tube wall, from
And it is not easy to block；
2. connecting impact tube on punching press mouth, stamping equipment can be connected to by impact tube, meet the punching press of different pressures
Demand, and solenoid valve is provided on impact tube, flexible adjustment is easy to control, and use is safe；
3. ash handing pipeline is equipped with jarring machine, jarring machine vibration will drive ash handing pipeline bounce, make ash vacantly in ash pipeline
Lu Zhong reduces defeated grey resistance, reduces ash deposition when defeated grey on ash handing pipeline；
4. ash handing pipeline is equipped with air blower, it can further improve the gambling plug phenomenon of ash handing pipeline, starting air blower supports
For ash along claiming to blow, defeated ash is more efficient.
