The invention discloses a wet desulfurization tower internal heat pipe heat-exchanging, water-saving, demisting and gypsum rain preventing device. The device is respectively provided with a desulfurization slurry pool, a flue gas inlet, a tray, slurry spraying layers, heat pipe heat exchange layers, a rectifier, demisters and a purified flue gas outlet from bottom to top, wherein the quantity of the slurry spraying layer is 3; the quantity of the heat pipe heat exchange layers is 6, and the heat pipe heat exchange layers are arranged in a certain angle staggered manner; and the coarse demister is positioned between the upstream and the downstream of a flusher, and the fine demister is positioned at the downstream of the flusher. The device has heat exchanging, condensing, water saving and demisting functions, can condense the flue gas without introducing a cooler or a cooling medium, and has the advantages of low cost, less energy consumption, high efficiency and easiness in replacement, so the device can effectively eliminate the gypsum rain.
Description
technical field [0001] The invention relates to the technical field of wet flue gas desulfurization, in particular to a device for heat exchange, water saving, fog removal and gypsum rain prevention in a heat pipe in a wet desulfurization tower. Background technique [0002] 90% of power plants in my country use limestone-gypsum wet desulfurization technology for desulfurization. Early wet desulfurization systems were equipped with gas-gas heat exchangers (GGH for short). A series of problems such as corrosion and blockage have emerged, and most power plants have canceled GGH at present. [0003] The cancellation of GGH will lead to lower exhaust gas temperature, lower flue gas lift height, and "gypsum rain" problem, which will have a great impact on the lives of nearby people. GGH cannot substantially eliminate "gypsum rain", so solving the problem of "gypsum rain" from the source is an urgent task to adopt limestone-gypsum wet desulfurization technology.
