Title:
FORCED CIRCULATION EVAPORATOR FOR SEWAGE TREATMENT OF FOSSIL FUEL POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2022/142184
Kind Code:
A1
Abstract:
Disclosed in the present invention is a forced circulation evaporator for the sewage treatment of a fossil fuel power plant, comprising: a gas-liquid separator, a tubular heat exchanger, and a circulating pump. A steam inlet, a material feed port, a material discharge port, and a condensate water discharge port are respectively formed on the outer side of the tubular heat exchanger; a material pipe and a heating pipe are provided inside the tubular heat exchanger; the material pipe is communicated with the material feed port and the material discharge port, respectively; the heating pipe is communicated with the steam inlet and the condensed water discharge port, respectively; the material discharge port is communicated with the interior of the gas-liquid separator through a liquid feed pipe; a material downflow port is formed at the bottom of the gas-liquid separator; the material downflow port is communicated with a material discharge pipe; and a liquid feed end of the circulating pump is communicated with the material discharge pipe, and a liquid discharge end of the circulating pump is communicated with the material feed port through a circulating pipe. The present invention performs multiple heating and gas-liquid separation on a raw material solution, and is suitable for the evaporation and concentration in industries such as chemical engineering, food, pharmacy, environmental protection engineering, and waste liquid evaporation recovery concerning fouling, crystallinity, high concentration, high viscosity, and insoluble solids.
