The invention relates to a heat accumulating type transcritical flue gas waste heat recovery apparatus for the utilization of transcritical low-temperature heat of exhaust gases from a heating furnace or a reactor in petroleum refining and chemical industry. The apparatus includes a tank boy (16) in which a plurality of sets of heat accumulating type coolers (6) is provided with each being provided with a flue gas inlet branch conduit (10), a flue gas outlet branch conduit (15), an air inlet branch conduit (18) and an air outlet branch conduit (13) as well as being provided with a flue gas inlet valve (9), a flue gas outlet valve (7), an air inlet valve (5) and an air outlet valve (8); the flue gas inlet / outlet branch conduits and the air inlet / outlet branch conduits of each set of heat accumulating type coolers (6) are communicated with flue gas inlet / outlet concentration conduits (11), (16) and air inlet / outlet concentration conduits (17), (14), respectively; the bottom of each ser of heat accumulating type coolers (6) is provided with a drainage liquid encapsulation conduit (20) and a check valve (4), the drainage liquid encapsulation conduit (20) is coupled into a liquid collection awl or a concentration conduit (3), the bottom of the liquid collection awl or the concentration conduit (3) is connected with a drainage conduit (2). The inventive apparatus can recover the waste heat of the flue gas below the temperature of a dew point.
Description
(1) Technical field [0001] The invention relates to equipment for recovering industrial flue gas waste heat. It is mainly used for the utilization of transcritical low-temperature heat of waste heat from tail gas of heating furnaces or reactors in petroleum refining and chemical and coal chemical processes. It can also be used for the recovery of flue gas transcritical waste heat in metallurgy, ceramics, building materials and other fields. It belongs to the technical field of petroleum refining, chemical industry, and coal chemical process energy saving. (2) Background technology [0002] In the fields of petroleum refining, chemical industry, and coal chemical industry, when the flue gas is lower than the dew point, it will cause serious dew point corrosion of equipment such as FCC regenerator, convection section of heating furnace, furnace wall, boiler air preheater, pipeline cecum, etc. Since the nitrogen and sulfur elements in the fuel generate NOx, SO2, and SO3 durin...
