Air purification system for printing workshop

Abstract

The invention discloses an air purification system for a printing workshop, belonging to the technical field of air purification equipment. The air purification system comprises an air inlet device and an air exhaust device, wherein the air inlet device is provided with a dust removal device, an air compressor is arranged at an outlet of the air inlet device, and the air compressor is used for compressing air exhausted by the air inlet device. The air purification system further comprises a control table and an air internal circulation device, wherein the air internal circulation device is used for removing dust in air in the printing workshop, and the control table is used for controlling operation of the air inlet device, the exhaust device, the air compressor and the air internal circulation device. The air purification system of the invention is used for air purification and dust prevention in the printing workshop, has the advantages of being good in dust removal effect, capable of preventing external dust from entering, convenient to maintain and the like, and can comprehensively reduce dust particle concentration of the printing workshop.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to an air purification system in a printing workshop. Background technique [0002] In the production process of packaging bags, the printing process is the most basic and the first process. Among the printing equipment currently used, whether it is flexographic printing or gravure printing, rotary printing is the main method, but rotary printing uses High-quality roll printing materials are prone to printing difficulties due to the adsorption of dust and other impurities, which will lead to a decrease in the quality of printed products and increase the reject rate. [0003] The measures taken for dust removal in the printing workshop are mainly air filtration and dust removal. In order to further improve the printing quality, some enterprises have built a dust-free workshop for packaging bag printing, and set up an air shower room at the entrance of the workshop....

AI Technical Summary

Problems solved by technology

[0004] Patent CN103574807A proposes an automatic ventilation and temperature control system for printing workshops, which uses cloth bags to remove dust from the air entering the workshop, but the bag dust collectors are often huge in size, and the dust removal efficiency varies with the quality of the filter material of the dust removal filter bag and the air-to-cloth ratio. The selection fluctuates greatly, and it is difficult to meet the requirements of a thousand-level dust-free workshop
