Embodiment Construction

[0018] As shown in the figure, the specific implementation method is as follows:

[0019] A solvent recovery system for a printing machine, comprising a sealed factory building and a printing machine arranged in the sealed factory building, the sealed factory building 4 is provided with an inlet 2 and an outlet 1, and the inlet 2 and the outlet 1 of the sealed factory building 4 are respectively arranged There is a dust removal device 9, and a plurality of vents 3 and lighting holes are provided on the surrounding walls of the sealed factory building 4 to ensure the air flow and lighting effects in the sealed factory building 4. The sealed factory building is also equipped with a dust collector for collecting the dust around the printing machine. The solvent collecting device 8 that has volatilized the solvent air and the solvent processing device 7 that is arranged outside the factory building for processing the air collected by the solvent collecting device 8 and purifying th...

Abstract

A solvent recovering system for a printing machine comprises a sealed workshop and the printing machine arranged in the sealed workshop, wherein an inlet and an outlet are arranged on the sealed workshop, and dust removal devices are arranged in the inlet and the outlet of the sealed workshop respectively; multiple ventilation openings and multiple daylighting holes are formed in surrounding walls of the sealed workshop, so that air flowing and daylighting effects in the sealed workshop are guaranteed. The system is characterized in that a solvent collecting device for collecting volatile-solvent-containing air around the printing machine is also arranged in the sealed workshop, and a solvent treating device for treating the air collected by the solvent collecting device and purifying the air to separate out a solvent is arranged outside the workshop. The volatile-solvent-containing air is collected by the designed integrated system and then enters a solvent separation system, so that the solvent can be separated from the air and is prevented from polluting the air, meanwhile, the solvent is recovered for reuse, and a large amount of cost is saved.

Description

technical field [0001] The invention relates to a recovery and reuse device for an easily volatile solvent, in particular to a solvent recovery system for a printing machine. Background technique [0002] With the improvement of the quality of life, more and more attention is paid to the beauty of the packaging box when giving gifts, so special printing factories for printing packaging boxes have also emerged. In the process of printing packaging boxes in printing factories, ink is required to facilitate Printing machines and other inks need to be diluted with diluents. During the dilution process, since the diluents are easy to volatilize in the atmosphere, and the amount of solvent used is relatively large, if the solvent is volatilized into the air, it will cause air pollution, and the solvent is used every day. The use amount is larger, and the cost is higher, which will cause a huge cost input shortage and cause serious air pollution. Contents of the invention [000...
