The utility model relates to a double-effect evaporation and concentration system, in particular to an embedded auxiliary starting heat pump double-effect evaporation and concentration system. The utility model aims to solve the problems of energy waste, poor operation stability, lower efficiency and incapability of normally starting low-pressure live steam in the conventional multi-effect evaporation and concentration system. A heat pump working medium circulating pipeline is communicated with an embedded heat pump evaporator; the heat pump compressor is mounted on a gaseous working medium pipeline in which a working medium flows from the embedded heat pump evaporator to the heat pump condenser in the heat pump working medium circulating pipeline; the heat pump throttling expansion deviceis mounted on a liquid working medium pipeline in which the working medium flows from the heat pump condenser to the embedded heat pump evaporator in the heat pump working medium circulating pipeline; the live steam auxiliary system and the electric quantity auxiliary system are installed on the embedded heat pump evaporator or the embedded heat pump condenser. Auxiliary steam or an electric heater is embedded into the heat pump unit, and the heat pump double-effect evaporation and concentration system can be rapidly and stably started under the condition of low steam pressure or no steam.
