Description of the Invention: [Technical Field of the Invention] The present invention relates to a "closed loop solvent recovery system" which is designed to form a closed loop by printing or painting a device and a recycling system. Or the gas volatilized by the coating device can be completely recovered in the device. After three times of heating and three cooling steps, the liquid-gas conversion is not only environmentally friendly but also energy-saving, and the volatile solvent is recycled, thereby reducing the solvent. Consumption, the best use status. [Prior Art] According to the conventional printing device (10, as shown in the first figure), the blower (11), the heating body (12) and the exhaust fan (13) are activated before the operation to make the oven ( 14) internally forming a hot air circulation space and maintaining a working temperature, so that the product is conveyed to the printing body (17) through the winding body (15) and the unwinding body (16). In (14), the product is indirectly contacted with the hot air sent from the introduction hole (142) of the air conductor (141) after being printed by the printing body (17), and the hot air is drawn out by using the lead-out hole (143). One in one out of the state to achieve the purpose of drying. The conventional structure described above has the following drawbacks: in particular, the solvent used for printing is generally a volatile harmful gas, and the residual gas after printing will be directly discharged by the exhaust fan (13) through the lead-out hole (143). In the air, the emitted gas is completely untreated. Except for the inability to recover the solvent effectively, it will cause serious pollution to the surrounding residents and the air, so that the ozone layer that harms the atmosphere will increase the environmental burden. As shown in the second figure, it is a schematic diagram of the plane action of another conventional method. The printing device (10) is connected to the discharge end of the exhaust fan (13) and is connected to a recovery system of activated carbon tank (181). 18), the residual gas after printing can be recovered by the exhaust fan (13) of the oven (14) and adsorbed in the activated carbon tank (181), and then desorbed by heating. Procedure and cooling to collect the activated carbon tank (181) The solvent inside and the water is discharged. Another conventional structure as described above has the following defects: (1) especially in the process of heating and desorption and cooling of the activated carbon tank (181), although part of the solvent can be made from water. Separation for recovery, however, some of the solvent will still remain in the discharged water, resulting in water pollution; (2) Because its activated carbon is a consumable, φ has a certain period of use, so it is not only inconvenient to replace it regularly. It also makes it necessary for users to waste the burden of replacing consumables and handling the cost of consumables. The present inventors have continually tested the process methods and products in the spirit of creation, in the spirit of creation, and in the creation of methods and installation methods. Through numerous experiments and years of experience, the present invention has been improved. The present invention has been further proposed. SUMMARY OF THE INVENTION B. The main object of the present invention is to provide a closed loop solvent recovery system that is designed to form a closed loop by a recycling system and a printing or painting device. The gas can be completely converted into three parts of the recovery system through three steps of heating and three times of cooling, and there is no leakage, so as to avoid the situation of water pollution and air pollution caused by the conventional printing device, thereby effectively improving the environmental benefits. A secondary object of the present invention is to provide a closed loop solvent recovery system in which a gas discharged from a printing or coating device is formed by a heat exchanger, a radiator, a condenser, and an evaporator of a recovery system to form a cooling liquid. The effect of gas 1273040 separation, so that the volatile cutting tank allows the solvent to be completely recovered = then condensed, solidified and condensed back to the best use state. Use, to reduce the consumption of solvent, for another purpose, the system, its printing or coating equipment for a closed loop solvent recovery
