Abstract

The invention relates to the technical field of power generation equipment, in particular to a fire coal sludge coupling power generation system. The fire coal sludge coupling power generation systemcomprises a boiler, a sludge conveying pump and a slag fetching machine. A slag well is connected to the bottom of the boiler, a sludge discharging opening is formed in the slag well, the sludge conveying pump is communicated with the slag well through the sludge discharging opening, the slag fetching machine is used for conveying sludge and dry slag in the slag well into a feeding opening of a dry slag machine, a discharging opening of the dry slag machine is connected with a feeding opening of a coal bucket, the feeding opening of the coal bucket right faces the coal outlet end of a coal conveying belt, a discharging opening of the coal bucket is communicated with a feeding opening of a coal mill, a discharging opening of the coal mill is communicated with a feeding opening of the boiler, a smoke outlet of the boiler communicates with a smoke inlet of a dust remover, and an ash outlet of the dust remover is communicated with an inlet of an ash storage. The fire coal sludge coupling power generation system saves energy, reduces water consumption, is more environment-friendly, and can achieve energy reutilization.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a coal-fired sludge coupled power generation system. Background technique [0002] Sewage treatment plants will produce a large amount of surplus sludge in the process of purifying sewage. These sludges are chemically unstable, prone to corruption, and have stench, which greatly affects the living environment of people around them. [0003] At present, in the sludge treatment method, the coupling power generation of sludge and coal combustion has the following advantages: First, it has good economic benefits and can promote sludge reduction, harmlessness, resource utilization and scale Disposal; second, the sludge is combusted with coal after the water content is reduced to 30%-35% after drying, and the proportion of sludge is not large, so it has little impact on coal-fired units; third, combustion Dioxins produced are basically negligible, other dust, SO 2 ...
