Abstract

The invention discloses a sludge and coal-fired integrated treatment system based on steam-water coupling, including a sludge incinerator, a coal-fired unit and a control device, which are configured to obtain the operating parameters of the sludge incinerator and the design of the coal-fired unit parameters; according to the operating parameters of the sludge incinerator, the main steam side of the sludge incinerator is coupled to the subsystem of the corresponding coal-fired unit; according to the design parameters of the coal-fired unit, the water supply system of the sludge incinerator is passed through the corresponding The water supply component is coupled to the water supply system of the coal-fired unit; the subsystems of the coal-fired unit at least include the main steam system, the hot section reheat system, the cold section reheat system and the auxiliary steam system; the water supply component is the first feed water pump, the first condensation One or more combinations of water pumps, first deaerators, valves and supporting pipeline accessories. The sludge and coal-fired integrated treatment system based on the steam-water coupling provided by the embodiment of the present invention improves the efficiency of sludge treatment by designing the steam-water coupling system between the sludge incinerator and the coal-fired unit.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an integrated treatment system for sludge and coal combustion based on steam-water coupling. Background technique [0002] In the sewage purification process, some solids or added chemicals cannot be removed, and these solids are collectively called sludge. Sludge is composed of organic matter and inorganic matter. It is a complex substance with a high water content. At present, the sludge incineration process is mainly used to heat and dry the dewatered sludge by using an incinerator, and then oxidize the organic matter in the sludge with high temperature. The sludge becomes a small amount of ash. [0003] Coal-fired power generation is a large-scale, large-scale, and efficient power generation method. Coal-fired power plants have the advantages of large unit capacity and high unit efficiency. Due to the new sludge incinerator supporting steam turbine generator set and...
