摘要
A multistage evaporator plant having combined vapor compressor and heat pump for recovery of the heat contained in the vapors. The evaporator section comprises several stages and a heat input, a condensate output and a vapor output. The vapor compressor can comprise a steam jet injector connected to a source of booster steam for providing steam power and connected to the heat input of the evaporator section, a distributor valve connected to an input of the steam jet injector. The heat pump can comprise an absorber connected to the condensate output of the evaporator and to the heat input of the evaporator on its output side, and to a port of the distributor valve, a heat exchanger connected via feed and return line to the absorber, a pressure reducing valve connected via the heat exchanger to the feed line, a boiler connected to the pressure reducing valve to receive feed and having an output for a return depleted mixture, a pump connected to the output for the depleted mixture of the boiler and to the return line via the heat exchanger, a condenser connected to the boiler and a control valve connected to the distributor valve and to the boiler heating provision for controlling the amounts of vapors required in the absorber and the boiler heating supply. The apparatus results in considerable decreases of energy expenditures compared to conventional apparatus.
