The invention discloses an absorption high-temperature heat pump system, belonging to the technical field of advanced energy source. The system is characterized in that a high-temperature absorption heat pump system capable of raising temperature by using residual-heat in a higher temperature position through a working medium circulation is designed on the basis of experimental study, and the high-temperature absorption heat pump system can effectively prevent the system from the corrosion of the working medium in action; an experimental sample is composed of five units, namely an evaporator, a regenerator, an absorber, a condenser and a heat exchanger which are compactly connected with each other through a pipeline rationally designed. When the system is in action, the SiO2 is added to combine with a LiBr solution to prepare an anti-corrosive organic composite silicon film online to reduce the corrosion of the solution to the system. The absorption high-temperature heat pump system has the advantages that the residual-heat at the higher temperature position is used for raising the temperature through the working medium circulation, so that the heat energy is effectively used, the energy is saved, and the nervous energy consumption problem in our country can be relieved; and the corrosion condition to the whole system is reduced by using an online film-forming process, the operation cost is reduced, and the productivity effect is high.
