Embodiment Construction
[0012] The present invention will be further described below with reference to the drawings and embodiments.
[0013] Such as figure 1 Shown: a comprehensive recovery system for polyimide film production, including batching tank 1, casting furnace 2, imine furnace 3 and winding system 4 arranged in sequence, in which the high temperature flowing out of casting furnace 2 The gas is fed into the casting furnace heat exchanger 5, and the gas after heat exchange continues to flow into the casting furnace condenser 6. The casting furnace condenser 6 condenses the gas obtained after heat exchange through the casting furnace heat exchanger 5 to obtain The solvent is recovered to the solvent recovery tank 7 for secondary utilization, and the condensed gas is returned to the casting furnace heat exchanger 5, mixed with the heat obtained by the high-temperature gas heat exchange, and then flows to the imine furnace heat exchanger 8; The high-temperature gas flowing out of the amine furnac...

The invention discloses a comprehensive recycling system for production of polyimide films. The comprehensive recycling system comprises a casting furnace (2) and an imine furnace (3), high-temperature gas flowing out from the casting furnace (2) is inputted into a heat exchanger (5) of the casting furnace, the gas subjected to heat exchange flows into a condenser of the casting furnace, the condensed gas flows back to the heat exchanger (5) of the casting furnace to exchange heat with the high-temperature gas prior to flowing towards a heat exchanger (8) of the imine furnace; high-temperature gas flowing out from the imine furnace (3) is inputted into the heat exchanger (8) of the imine furnace for heat exchange, and heat acquired by heat exchange is mixed with heat inputted by the heat exchanger (5) of the casting furnace prior to being inputted into the casting furnace (2) for recycling. Since the heat acquired by heat exchange is mixed with inputted heat prior to being inputted into the casting furnace for recycling, and 90% of solvents can be recovered by a solvent recycling tank, the comprehensive recycling system has functions of efficiency improvement, consumption reduction and environment protection and is suitable for popularization and utilization.
Description
Technical field [0001] The invention relates to the field of polyimide film production, in particular to a comprehensive recovery system capable of recycling and secondary utilization of heat energy and solvent generated in the production of polyimide film. Background technique [0002] In the existing polyimide film production system, the high temperature gas and waste solvent generated by the casting furnace and the high temperature gas generated by the imine furnace are directly discharged, which pollutes the environment and increases energy consumption, which is not conducive to sustainable development. Summary of the invention [0003] The purpose of the present invention is to provide a comprehensive recovery system capable of recovering and reusing the heat energy and solvent generated in the production of polyimide film in view of the defects in the prior art. [0004] The purpose of the present invention is solved by the following technical solutions: [0005] A comprehensi...
