Large circulating fluidized bed boiler combined deslagging device

Abstract

The invention relates to the technical field of fluidized bed boiler deslagging, and discloses a large circulating fluidized bed boiler combined deslagging device. The large circulating fluidized bedboiler combined deslagging device comprises a first slag pot and a second slag pot, the first slag pot is of a hollow cuboid structure with an opening in the bottom, the second slag pot is of a hollowcuboid structure with openings in the top and the bottom, the top of the second slag pot is located in the first slag pot, a pot brim is fixed to the top of the second slag pot, and the pot brim is of a rectangular structure with a hole formed in the middle. Slag discharge pipelines of a plurality of boilers can be connected to the device through a plurality of connectors, so that slag of the plurality of boilers can enter the device, the slag generated by the plurality of boilers is temporarily stored, and then the slag in the device can be discharged and transported away by starting an electric valve. According to the device, slag generated by multiple boilers can be contained, the combined slag discharging function is achieved, the slag discharging cost is greatly reduced, and a largeamount of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of slag discharge for fluidized bed boilers, in particular to a combined slag discharge device for large circulating fluidized bed boilers. Background technique [0002] Fluidized bed, referred to as fluidized bed, is a kind of reactor that uses gas or liquid to pass through the granular solid layer to make solid particles in a suspended state, and to carry out gas-solid phase reaction process or liquid-solid phase reaction process. After the reaction, it is necessary to discharge the dross of the waste gas. In the factory, in order to increase the production efficiency, multiple fluidized bed boilers are often installed in the factory area, and during the use of multiple fluidized bed boilers, generally Separate slagging, which leads to the need to install slag storage and slag handling devices at each fluidized bed boiler, which greatly increases the slagging cost of the fluidized bed boiler, thereby indir...
