The invention discloses an ORC power generation system utilizing multiple heat-source plate heat exchangers, and belongs to the technical field of power generation. With the ORC power generation system utilizing the multiple heat-source plate heat exchangers, the problem that an existing ORC power generation system cannot meet the requirement of being applicable to different heat sources is solved. The system comprises a plate-type evaporator, a plate-type preheater, an expansion machine, an electric generator, a condenser, a working medium storage tank and a working medium pump. The plate-type evaporator comprises an upper partition board, a lower partition board and multiple heat transmission sheets. A heat source flow channel A, a heat source flow channel B, an organic working medium outlet C and an organic working medium flow channel C are formed by the upper partition board, the lower partition board and the multiple heat transmission sheets. The plate-type preheater is the same as the plate-type evaporator in structure. Two different waste heat sources pass through the plate-type evaporator and the plate-type preheater in sequence to carry out heat exchange with organic working media, are heated to become overheated organic working media, enter the expansion machine to do work to drive the electric generator to generate electricity, and then enter the condenser to exchange heat with cooling water, and the cooled working media enter the working medium storage tank and then are boosted and pumped into the plate-type preheater for circulation by the working medium pump.
Description
technical field [0001] The invention relates to an ORC power generation system using multiple heat source plate heat exchangers, belonging to the technical field of power generation. Background technique [0002] At present, ORC (Organic Rankine Cycle, Organic Rankine Cycle) power generation system is used in waste heat recovery in various industries, such as: industry, metallurgical industry, chemical industry, etc. For different industries, the conditions of waste heat sources are also different. Usually, an ORC power generation system can only be used for waste heat utilization of a single heat source, and often cannot meet the multiple waste heat sources generated in industrial production. When there are multiple waste heat sources, they can only be utilized by adding equipment, which has poor applicability and high cost. Contents of the invention [0003] Aiming at the problem that the applicability of the existing ORC power generation system cannot meet the conditio...
