Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explanation.
Referring to Fig. 1, the multistage delivery system of a kind of furnace gas ash strength, it comprises cone pump 8; Cone pump has vent valve 6 and intake valve 10, and the cone pump top connects fly-ash separator awl section 18, and the cone pump bottom connects ash handing pipeline 13 through bleeder valve 12; Ash handing pipeline one end is provided with air compressor machine or gas-holder 14; The ash handing pipeline the other end is received 16 connections of powder device through Cang Ding and is received grey storehouse 15, is provided with successively between described cone pump and the fly-ash separator awl section and unloads grey gas check valve 3 and feed valve 5, and described cone pump upper end is provided with cone pump high charge level meter 7; The lower end of cone pump is provided with the low level gage 9 of cone pump, and said fly-ash separator lower end is provided with the low level gage 1 of fly-ash separator.Also be provided with equalizing line 19 between described cone pump and the ash handing pipeline through equilibrium valve 11 controls.Described cone pump can be provided with two or more, is connected with ash handing pipeline through bleeder valve side by side.Describedly receive also to be provided with on the grey storehouse pulse backblowing sack cleaner 17.Between described storehouse material pump and fly-ash separator awl section, also be provided with manual ball valve 2.Between described storehouse material pump and fly-ash separator awl section, also be provided with ripple compensation pipe 4.
This technology is provided with two covers or overlaps ash-transmission system more, and two covers or many cover systems can move by monophyly, but also dual system or multisystem operation both can be interrupted defeated ash, also can fail ash continuously.System control mode is divided into automatically, the other control of remote manipulation, machine and hold function.
The charging process: when the low level gage 9 of cone pump send ask the material signal after, the air valve 6 that begins to rehearse earlier, start discharging again grey gas check valve 3 and feed valve 5, after the high charge level meter 7 of treating cone pump sends the full signal of material, whole charging end of processing.Close feed valve 5 earlier and unload grey gas check valve 3, close vent valve 6 again.
Defeated grey process: drive equilibrium valve 11 earlier, drive air valve 10 again into, drive bleeder valve 12 at last, after the low level gage 9 of treating cone pump sends the material spacing wave, whole defeated grey end of processing.Close bleeder valve 12 earlier, close intake valve 10 and equilibrium valve 11 again.This process moves in circles.
When the low level gage of fly-ash separator bottom is reported to the police, do not allow in cone pump, to feed, in order to avoid the poisonous coal gas in the fly-ash separator leaks in the cone pump with the coal gas ash.
