The invention relates to composite equipment for flue gas waste heat recovery and dust cleaning, belonging to the technical field of flue gas waste heat recovery and dust cleaning. The equipment comprises a heat exchange and absorption compound device, a recuperative heat exchanger, a precipitate collection and pollutant discharge device, a solution pool and a liquid pump, wherein a liquid distributor is arranged at the top of the heat exchange and absorption compound device, the recuperative heat exchanger is located at the lower part of the heat exchange and absorption compound device, and the precipitate collection and pollutant discharge device is arranged at the lower part of the heat exchange and absorption compound device; the heat exchange and absorption compound device comprises a flue gas inlet section, a flue gas inlet diversion section, a heat exchange and absorption section, a flue gas outlet liquid baffle diversion section and a flue gas inlet section, and a liquid mesh type liquid membrane distribution net is arranged inside the heat exchange and absorption section. Waste heat recovery and purification treatment are integrated, sensible heat and latent heat of exhausted flue can be recovered, the composite equipment also have the actions of corrosion prevention, dust removal, scale prevention, purification treatment and the like, flow resistance and energy consumption of fans and water pumps are also reduced, the cost of products is lowered, and the deep recovery of flue gas waste heat is achieved.
Description
technical field [0001] The invention relates to a composite equipment for recovery and utilization of waste heat of flue gas and dust removal and purification, in particular to a low-resistance type heat exchange and flue gas purification and dust removal integrated composite device utilizing the heat energy of condensation of flue gas, which belongs to the recovery and utilization of waste heat of flue gas and dust removal In the field of purification technology, it can be used for flue gas preheating, recycling and dust removal and purification of thermal power equipment such as ordinary coal-fired boilers, direct-fired engines, and cogeneration. Background technique [0002] Common boilers, direct-fired turbines, cogeneration and other thermal power equipment have high exhaust gas temperatures, most of which are above 120-200°C, resulting in energy waste and environmental pollution. The thermal efficiency is generally lower than 90%. Coal-fired boilers Generally less than...
