As shown in Figure 1, a kind of pneumatic ash removal system, comprise at least one group of storehouse pump, for storehouse pump provides compressed-air actuated compressed air source unit 6, the control setup that is electrically connected with source of the gas and collect grey storehouse, described every group of storehouse pump comprises the pump housing 1, is located at vaporizing chamber and fluidising chamber, the flue-dust retainer 2 being connected with pump housing opening, the ash pipeline 3 being connected with vaporizing chamber in the pump housing and is located at pump housing pressure sensor 4, and the other end of ash pipeline 3 is communicated with the grey storehouse of collection; Pump housing opening part is provided with metering unit for controlling material content and for opening and closing the inlet valve 12 of the pump housing; Compressed air source unit is communicated with the pump housing by gas piping 60, on gas piping with in the pump housing, is provided with pressurizing valve 62 with junction, is connected with air inlet valve 66 on gas piping; Ash pipeline and the pump housing 1 junction are provided with bleeder valve 33, described pressure sensor, metering unit, inlet valve, bleeder valve and pressurizing valve are all electrically connected with control setup, described metering unit is level-sensing device 7, also can be time meter, described compressed air source unit is provided with pressure transformer 61, and described gas piping 60 is provided with the flow regulating valve 63 and the reducing valve 64 that are electrically connected with control setup respectively.
Native system each to carry a storehouse pump flying dust be a working cycle, each working cycle is made up of four-stage, its principle is as follows:
Charging stage
Pump housing inlet valve, blow off valve are opening, air inlet valve, bottom inflow valve on gas piping, blow stifled valve and bleeder valve is closed condition, and dry ash enters the pump housing by flue-dust retainer.When stock position, arbitrary storehouse arrives preset value, system is closed inlet valve and the blow off valve of this group storehouse pump automatically, and the charging stage finishes.If the charging timing that program is set is in advance arrived, and stock full signal in storehouse still shows while providing, and inlet valve also can cut out automatically, and the charging stage also will finish, and storehouse pump enters the fluidisation pressure period of next working cycle.
The fluidisation pressure period
Inlet valve, blow off valve, unimpeded valve and bleeder valve on the pump housing are closed condition, air inlet valve, the bottom inflow valve of pump housing gas piping are opened, and pressurized air enters from the vaporizing chamber of storehouse pump bottom, pass fluidising chamber after diffusion, when material is by abundant fluidisation, the air pressure in pump also rises gradually.
Delivery phase
If carry bleed pressure to satisfy condition (being greater than 0.45Mpa), other one group of storehouse pump is not carried with plugging and is reported to the police, and first storehouse pump opens bleeder valve in 3 seconds by time delay after dropping into automatically, after bleeder valve is opened, storehouse pump carries timing to start, now closed condition of inlet valve, blow off valve; After bleeder valve is opened, bottom inflow valve is opened in time delay for 2 seconds, then the air inlet valve of gas piping is opened in time delay for 2 seconds, unimpeded valve is opened in time delay for 5 seconds again, pressurized air enters ash pipeline, and meanwhile, ash pipeline internal pressure increases, flying dust evenly enters ash pipeline, realizes the object of the remote smooth delivery of power of dry ash.
When fly ash carry in the pump of storehouse complete, pipe resistance declines, and storehouse pump internal pressure reduces gradually, when pressure sensor senses after the threshold pression (can adjust 0.06Mpa according to actual conditions) arranging in pressure is lower than program, show that delivery phase finishes, and enters purge stages.If when the storehouse pump that program is set in advance carry timing (5Min) to after manifold pressure be still greater than the threshold pression (0.06Mpa) designing in program, show that storehouse pump conveying is not smooth, now, bottom inflow, pipeline air-inlet, unimpeded valve, bleeder valve are closed simultaneously, and this storehouse pump stops carrying and plugging alerting signal occurs; If when line pressure is higher than 0.28Mpa, close pipeline air-inlet, equipressure is during lower than 0.18Mpa, then opening conduits air inlet; If storehouse pump pressure reaches 0.33Mpa, close bottom inflow, during by the time lower than 0.18Mpa, then opening conduits air inlet and bottom inflow; If when storehouse pump pressure reaches 0.38Mpa, close unimpeded valve, while waiting lower than 0.18Mpa, then opening conduits air inlet, bottom inflow and unimpeded valve.
Purge stages
Now inlet valve, blow off valve are still closed condition, bottom inflow valve unimpeded valve and bleeder valve are opening, purging timing (directly setting 15 paper money clocks in system) starts, after purging timing is arrived, storehouse pump cuts out unimpeded valve, air inlet valve by corresponding delay, and time-delay closing bleeder valve, and this one-phase Main Function is, by pure compression air, residual flying dust is sent into the grey storehouse of collection, finally be pure air flow condition, systemic resistance drops to stationary value; This stage is quantitatively to carry, and purge time one arrives, and air inlet valve, unimpeded valve are closed automatically, then time-delay closing bleeder valve, proceed to the charging stage.
