Embodiment Construction

[0077] As shown in Figure 1: through the flue 55, the flue gas is introduced into the flue gas heat exchanger 60, the heat pipe evaporator 62, the expander 67, and the thermosiphon smoke gas heating evaporator 70 to exchange heat and cool down the flue gas, so that the flue gas The water vapor exothermicly condenses, dew condensation atomizes, the acid gas in the flue gas forms an acid solution, and the acid solution reacts with the alkaline dust in the flue gas to form a salt mixture, which expands the flue gas and reduces the flue gas Flow rate, so that the dust in the flue gas settles, the flue gas is introduced into the spray washing dust collector 77, the flue gas is washed and dedusted, the flue gas is introduced into the water-cooled flue gas device 15, the flue gas is further cooled, and the flue gas is introduced into cold water for dissolution The flue gas desulfurizer 23 uses the cold water sprayed by the cold water sprayer 25 to dissolve the sulfur dioxide gas in th...

Abstract

A fume desulfurizer based on dissolving in cold water, elecrolyzing and adding alkali for dissolving and absorbing SO2 gas and then releasing it is composed of flue, fume heat exchanger, heat-tube evaporator, flash tank, distiller, showering duster, water cooler, desulfurizing unit by dissolving SO2 in cold water, cold water shower, water collector, draught fan, gas compressing condenser, anode electrolyzer, cathode electrolyzer, deposition unit, DC power supply, etc.

Description

Technical field [0001] The invention relates to the separation and extraction of sulfur dioxide (SO 2 ) and other gases, the method and device for producing distilled water by using the heat of flue gas to heat water. It belongs to the field of environmental protection. Background technique [0002] Currently, the power industry is responsible for SO 2 Major Sectors of Pollution and Acid Rain, SO 2 A large amount of emissions have caused serious air pollution in Chinese cities. SO 2 The discharge has caused serious acid rain pollution and ecological damage, so its environmental impact has received great attention. A report by the World Bank, "Clear Water and Blue Sky——Prospecting China's Environment in the 21st Century" estimated the impact of China's air pollution and water pollution on the environment. According to the value of willingness to pay method, China's current (1995) loss of air and water pollution accounts for about 8% of GDP; if the human capital valuatio...
