The invention provides a double-effect evaporator system, which includes a waste water tank, a condensed water tank, a first steam delivery pipeline, a first evaporation heat exchange component, a second evaporation heat exchange component, and a second steam delivery pipeline. The heat exchange assembly includes a first evaporator and a first circulation pipeline, the drain of the first evaporator communicates with the second water inlet of the second evaporator through the first circulation pipeline, and the second evaporative heat exchange assembly includes a second evaporator And the evaporation separator, and the outlet of the first evaporator is connected to the second evaporator through the concentration pipeline, the water outlet of the evaporation separator is connected to the water inlet of the second evaporator through the second circulation pipeline, and the bottom of the evaporation separator A first drain pipe is also provided. In the present invention, both the first evaporative heat exchange component and the second evaporative heat exchange component adopt the method of cyclic evaporation, which can ensure that both the first evaporator and the second evaporator are difficult to foul, and can maximize the utilization of steam heat energy ,Energy saving.
Description
Technical field [0001] The invention relates to an evaporator, in particular to a double-effect evaporator system. Background technique [0002] In order to meet the national environmental protection requirements, SO 2 , SO 3 As the main cause of "colored plume" and acid rain in flue gas emissions from domestic power plants or other coal-burning equipment, flue gas desulfurization treatment has become the main treatment method. At present, coal-fired power plants mainly adopt limestone-gypsum wet flue gas desulfurization process. In this process, the desulfurization circulating slurry continuously absorbs chlorides from flue gas and limestone, resulting in an increase in the concentration of chloride ions. The increase in its concentration will bring many adverse effects, such as: inhibiting the dissolution of limestone; reducing the pH value of the slurry ; Affect the absorption effect of sulfur dioxide; make calcium sulfate (CaSO 4 ) Easy to scale; also easy to cause corrosion...
