摘要（英）：

The utility model relates to the technical field of graphite heat conductive film production devices, and particularly relates to a preheating system for graphite heat conductive film production. The preheating system is characterized in that a boiler is connected with a steam turbine; the steam turbine is connected with a condenser; the condenser is connected with a low-pressure heater by virtue of a condensate pump; the low-pressure heater is connected with a deaerator; the deaerator is connected with a high-pressure heater; the steam turbine is connected with an absorption type heat pump; and the absorption type heat pump is connected with a cooling tower. The preheating system is simple and convenient to run, operate and maintain, has a long service life of over 30 years, has high heating capability since the maximal heating of a two-stage heat pump can be 15MW, has a comprehensive energy-saving efficiency of 50 percent, enables the heat efficiency of the whole extraction condensing generator system to be improved, and has the advantages of low noise, no vibration and low mounting requirement.
