Intelligent circulation combustion system for large hearth coal

Abstract

The invention relates to an intelligent circulation combustion system for large hearth coal. The intelligent circulation combustion system comprises a gas-solid separator. The gas-solid separator comprises a gas inlet pipe, an exhaust pipe, a body and a return pipe. The system further comprises an anti-blocking mechanism and a grinding mechanism. The anti-blocking mechanism comprises a drive shaft, a supporting rod, a fan blade, two mounting bearings and two knocking assemblies. The grinding mechanism comprises a grinding block, a columnar concave opening, a locating assembly, a spring, two supporting wheels and at least two convex strips. Each knocking assembly comprises a rotating plate, a rubber column, a knocking block and two connecting rods. The locating assembly comprises a limitinggroove and a limiting block. In the intelligent circulation combustion system for large hearth coal, the body can be knocked by the anti-blocking mechanism, coal particles in the body are loosened, the probability that the coal particles are blocked in the body is reduced, and practicality of the gas-solid separator is improved; and the coal particles of the grinding mechanism can be ground, thesizes of the coal particles are reduced, and combustion efficiency of the coal particles is improved.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to an intelligent circulation combustion system for burning coal in a large furnace. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. When the boiler burns coal, the solid particles insid...

AI Technical Summary

Problems solved by technology

When the boiler burns coal, the solid particles inside the furnace will be discharged together with the flue gas, which will cause the loss of coal materials and reduce the combustion efficiency of the boiler. Therefore, it is necessary to realize the recovery and reuse of coal materials through a gas-solid separator

[0003] When the gas-solid separator in the prior art is in use, a large amount of coal particles accumulate at the bottom of the gas-solid separator, which will cause the blockage of the gas-solid separator and reduce the efficiency of coal recycling. Not only that, but if the coal particles are large, it will It will lead to insufficient combustion of coal and reduce the combustion efficiency of the boiler
