(2) furnace hopper → → Wet-type spiral dragveyer → → wet type slag crusher → → punching ash slag runner → → ash pump system → → storage ash field precipitation stores lime-ash; (ash clarification of water Hou Fan factory reuse);
(3) drainage bin system → → dress slag car outward transport in furnace hopper → → Wet-type spiral dragveyer → → wet type slag crusher → grey slag runner → → ash pump system → → factory of → punching; (buck sluiceway after drainage bin precipitates uses);
2, dry slag disposal mode:
(4) furnace hopper → → slag-draining device (slag inclusion pressurizing unit) → → air-cooled slag drying machine → → slag storehouse → → dress slag car outward transport;
(5) sell outside furnace hopper → → slag-draining device (slag inclusion pressurizing unit) → → air-cooled slag drying machine → → slag storehouse → → → → disintegrating machine → → fine slag storehouse → → groove tank car entrucking;
The collection of furnace bottom lime-ash is processed in process by above-mentioned 2 big class 5 kinds at present, equal Shortcomings part. By comparison, technique core technology of the present utility model is more simple and direct efficiently:
Sell outside furnace hopper → → high-temperature ash fine crusher → → fine slag storehouse → storehouse pumping system → groove tank car entrucking.
For this, this utility model have studied a kind of boiler high temperature lime-ash device in small, broken bits, can the more particularity in high-temperature ash process in small, broken bits at the bottom of good utilisation coal boiler, under the premise of, long-term operation safe and reliable in safeguards system, optimize collection processing method and the device of coal-burning boiler furnace bottom ash slag.
