An evaporative concentrator of a reduced pressure heat pump system has been introduced in which the pressure is reduced by a pressure reducing means and the liquid is boiled below a normal boiling point to take out a concentrate. Further, this depressurization heat pump type evaporative concentration apparatus employs a method in which condensed water condensed and liquefied in the cooling vessel is recovered in a sump by depressurizing means using an ejector and a liquid feed pump.

In that case, however, the surface temperature is substantially higher in the portion in the air due to the difference in heat transfer effect. Become. Therefore, if the supplied waste liquid is directly sprinkled on this, an unpleasant gas may be generated due to rapid heating. As a countermeasure, it is necessary to adjust the supply amount or to keep the temperature of the heating means in the air below the gas generation temperature. Alternatively, the heating means may be divided into the inside of the liquid and the outside of the liquid to control the temperatures separately.
