Air distribution and deslagging device of fluidized bed boiler and fluidized bed boiler

Abstract

The invention relates to an air distribution and deslagging device of a fluidized bed boiler and the fluidized bed boiler. The air distribution and deslagging device comprises a plurality of horizontally arranged air pipes, wherein a plurality of open pores for exhausting air are formed in each air pipe along the length direction of the air pipe; each open pore is provided with an air cap; and at least one ash hopper is arranged below the plurality of air pipes. After the air distribution and deslagging device is improved, a large object can automatically fall from the ash hopper, accumulation is not caused, and poking slag by operating personnel is not needed, so that the labor intensity of the operating personnel is relieved, and the scald accident caused by poking the slag is avoided. No accumulation on the bed surface can be caused, the fluidization of the boiler is normal, and the added fuel coal is reduced, so that the consumption of coal is greatly reduced, and more than 5000 tons of coal can be saved by each boiler every year. No accumulation is generated by the boiler, and the operation period is prolonged, so that the starting / stopping frequency of the boiler is reduced, the starting / stopping expense of the boiler is reduced, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to an air distribution and slag discharge device for a fluidized bed boiler and a fluidized bed boiler. Background technique [0002] In the prior art, the bed surface of the fluidized bed boiler is composed of an air distribution plate and an air cap. The air distribution plate is equipped with multiple slag discharge pipes, usually three slag discharge pipes, and larger debris cannot be automatically discharged during operation. , It will accumulate for a long time, resulting in poor fluidization of the boiler and forced to shut down the boiler for treatment. The operating cycle of the boiler is greatly shortened. At present, technical defects have caused the boiler to run for a short period. Normally, the boiler should be shut down within 30 days to clean up the iron wire and other sundries on the bed surface. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the d...
