[0002] At present, organic solvents are used as raw materials for printing patterns or characters on packaging bags. During the drying process of packaging bags by printing machines, organic solvents evaporate and enter the atmosphere with the exhaust air. At present, heat pumps are used for drying of printing machines. method, but there is a disadvantage that the heat pump must be supplemented by fresh air, and the printing machine always has exhaust gas emissions, which is not environmentally friendly

The invention relates to a printing heat pump condensation closed no-emission drying system for drying printed matters by using a heat pump. The system comprises a printer main body and a heat pump main body; the printer main body comprises a hot wind inlet and a waste gas outlet; and the heat pump main body comprises a compressor, an evaporator, a throttling valve, a condenser, a compressor, a condenser, a throttling valve and an evaporator to form a refrigerant loop. The system is characterized in that the heat pump main body further comprises an intake port and an exhaust port; the intake port is conducted with an intake port of the evaporator; an exhaust port of the evaporator is conducted with an intake port of the condenser; an exhaust port of the condenser is conducted with the exhaust port; a closed wind channel is formed among the intake port, the evaporator, the condenser and the exhaust port; the exhaust port communicates with the hot wind inlet; the waste gas outlet communicates with the intake port; and an organic solvent recoverer is arranged below the evaporator. The system is reasonable in structural design; waste gas containing organic matters is not exhausted outside, and is totally recovered; as the solubility of the organic matters is reduced, fresh air has no need to feed; and the air is only circulated between the printer and the heat pump, so that the energy is saved, and the air volume is higher.
Description
technical field [0001] The invention relates to a printing heat pump condensation closed type non-emission drying system which uses a heat pump to dry printed matter. Background technique [0002] At present, organic solvents are used as raw materials for printing patterns or characters on packaging bags. During the drying process of packaging bags by printing machines, organic solvents evaporate and enter the atmosphere with exhaust air. At present, heat pumps are used for drying of printing machines. method, but there is a disadvantage that the heat pump must be supplemented by fresh air, and the printing press always emits exhaust gas, which is not environmentally friendly. Contents of the invention [0003] Therefore, the object of the present invention is to provide a printing heat pump condensing closed type non-emission drying system that can recycle organic matter and does not discharge waste gas to the outside. [0004] The purpose of the present invention is ach...
