Control system for printing books and periodicals environmentally friendlily and green production method

Abstract

The invention discloses a control system for printing books and periodicals environmentally friendlily and a green production method. The control system for printing the books and the periodicals environmentally friendlily comprises a printing ink recycling system, a cleaning cloth recycling system and a cleaning agent recycling system. The printing ink recycling system form a recycling closed loop by a printer, a small automatic ink supplying device, an ink fountain isolating device and a waste printing ink recycling device. The cleaning cloth recycling system forms a recycling closed loop bya printer, cleaning cloth and a cleaning cloth recycling cleaning device. The cleaning agent recycling system forms a recycling closed loop by a cleaning cloth recycling cleaning device and a cleaning agent recovering and filtering device. A reasonable and low-cost book and periodical green printing and production method can be provided by means of the control system. Emission of wastes is reduced and the printing auxiliary materials are recycled effectively to the maximum extent while low VOCs emission of a book and periodical printing production line is ensured. Therefore, functions of energy conversation and emission reduction and efficient recycling are achieved.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and emission-reduction control for book production lines, and in particular relates to a control system and a green production method for realizing green and environment-friendly printing of books and periodicals. Background technique [0002] Printing originated in China and originated from the unique seal culture of the Chinese. It is a long-inherited cultural transmission method and an important traditional industry in China. my country is already a printing power in the world. In the printing process, ink and solvent The amount of discarded rags is quite large, which has become a large amount of solid pollutants in the printing industry. If it cannot be effectively treated, it will bring serious pollution to the surrounding environment and become one of the daily huge consumption of printing companies. [0003] At present, VOCs emissions in the book printing industry mainly come from the ...

AI Technical Summary

Problems solved by technology

[0005] Due to the current printing enterprises of books, labels, cartons, packaging, etc., in terms of controlling VOCs emissions, reducing production losses, and saving resources, etc., they mainly use new environmentally friendly raw and auxiliary materials (such as low-alcohol fountain solution, water-based varnish, white latex, etc.), Improved process measures (installation of central ink supply system, fountain solution filtration and recovery system, automatic blanket cleaning device, etc.), production plant closure, VOCs centralized treatment and other methods to achieve green environmental protection printing, although these measures can better control the production line VOCs emissions, but the investment in fixed assets is large, the maintenance cost is high, and the burden on the enterprise is increased; at the same time, there is no good way to control and reuse the waste ink and waste rags generated in the printing process, and too much is discarded. Enterprises bring a lot of waste, but also bring great challenges to environmental protection, which brings great troubles to enterprise managers

In short, at present, the investment in fixed assets in the green printing control process of books and periodicals is large, which can only control VOCs emissions, but cannot effectively control the generation of waste, and it is difficult to achieve the goals of energy saving, emission reduction, and effective recycling. Therefore, it is necessary to develop more Appropriate green printing control system and production method, so as to achieve low cost investment, good VOCs control, less waste discharge, to meet the current green printing needs of manufacturers and society
