Liquid evaporation, concentration and drying integrated treatment method

The invention relates to the technical field of liquid treatment, in particular to a liquid evaporation, concentration and drying integrated treatment method. The treatment method comprises the following steps: pumping a stock solution into an evaporator, heating the stock solution by feeding high-temperature steam into a heat exchanger in the evaporator, evaporating, concentrating; evaporating and concentrating the stock solution in the evaporator tank to form a concentrated solution, which flows into a hot well at the bottom of the evaporator; mixing the concentrated solution in the hot welland an incoming solution, pumping the mixed solution back to the evaporator, evaporating, concentrating, circulating and evaporating continuously; pumping the concentrated solution into a dryer whenthe concentrated solution reaches a certain concentration, evaporating and drying the concentrated solution by the dryer until the concentrated solution is completely dehydrated to form a cured product, and discharging the cured product out of the equipment. According to the treatment method, the drier is adopted to replace equipment such as a centrifugal machine, so that the problems of high equipment failure rate, frequent cleaning and equipment abnormality caused by high boiling point after the mother liquor of the concentrated liquor flows back to the evaporator are solved, and the treatment method is suitable for full-scale treatment of high-salinity high-organic-matter liquid and has the characteristic of being suitable for large-scale application.
