The invention relates to the technical field of flue gas waste heat recovery, in particular to a flue gas hydrothermal recovery device and method. The flue gas hydrothermal recovery device comprises avertically-through box body and a membrane assembly arranged in the box body; a flue gas inlet and a flue gas outlet are formed in the through upper and lower opposite surfaces of the box body; a cooling water inlet water chamber and a cooling water outlet water chamber which are communicated with the membrane component are arranged on two side walls adjacent to the two through opposite surfacesof the box body; and the cooling water inlet water chamber and the cooling water outlet water chamber are oppositely arranged in parallel. According to the device, flue gas hydrothermal recovery is conducted through the membrane assembly, latent heat and sensible heat in flue gas can be efficiently recovered at the same time, the waste heat recovery efficiency of a conventional device and method is improved, water vapor in the flue gas can be recycled in a high-cleanliness mode, the quality of recovered water is high, corrosion of acid and alkaline gases contained in the flue gas to the recovery device is effectively avoided, and the device and method are particularly suitable for hydrothermal recovery of the flue gas with the high heat and moisture content.
Description
technical field [0001] The invention relates to the technical field of flue gas waste heat recovery, in particular to a flue gas water heat recovery device and a method thereof. Background technique [0002] At present, with the improvement of the concept of energy saving and the improvement of environmental protection requirements, more and more enterprises have begun to recover the high-temperature flue gas discharged from the boiler through the flue gas waste heat recovery device to achieve the purpose of reducing the exhaust gas temperature and saving fuel at the same time. . In addition to a large amount of sensible heat, the flue gas also contains a large amount of moisture, which exists in the form of water vapor. The water vapor contains a large amount of latent heat of vaporization. Therefore, if the flue gas containing a large amount of moisture and waste heat is discharged directly, it will not only cause Waste of resources and energy, but also because the flue g...
