A kind of pneumatic adjustment system of liquid phase deacidification equipment

Abstract

The invention discloses a pneumatic adjustment system of a liquid-phase deacidification equipment, comprising an air source device, a first air delivery pipe, a blowing device, a nozzle device, a nozzle atomization device, a nozzle opening and closing control device, a stirring tank device, and a stirring tank adding device. The air outlet of the air source device is connected to the air inlet end of the first air pipe, and the air outlet end of the first air pipe is respectively connected with the blowing device, the spray nozzle atomization device, the nozzle opening and closing control device, and the stirring device. The tank pressurizing device is connected, the nozzle device is respectively connected with the nozzle atomizing device, the nozzle opening and closing control device and the stirring tank device, and the stirring tank pressurizing device and the stirring tank pressure relief device are installed on the stirring tank device. The system of the invention can realize automatic liquid spraying and blowing, and in the whole processing process, real-time collection of various process parameters can be performed, so that it is convenient to adjust each process in real time, and the pH value of the paper after spraying can be controlled and easily controlled. At the same time, it can improve the deacidification efficiency and reduce the work intensity of operators.

Description

technical field [0001] The invention relates to the technical field of deacidification equipment, in particular to a pneumatic adjustment system of a liquid phase deacidification equipment. Background technique [0002] According to incomplete statistics: the pH value of paper documents in my country in the 1920s and 1930s was below 4.0, which was in a state of severe acidification. The pH value of paper documents in the 1950s was below 5.0, which was in a more serious acidification state. During the slow aging process of paper, the degree of acidification is directly related to the rate of deterioration. Acidification of paper will reduce the folding strength of paper and cause paper damage. Deacidification technology has become one of the most important measures for paper protection. [0003] The current small-scale liquid phase deacidification equipment is mainly sprayed with a hand-held spray gun. The gas pressure and spray flow rate of the entire deacidification proces...

AI Technical Summary

Problems solved by technology

[0003] The current small-scale liquid-phase deacidification equipment mainly uses hand-held spray guns for spraying. The gas pressure and spraying flow rate of the entire deacidification process are all manually adjusted without real-time monitoring functions. The acid quality is greatly affected by human factors, and the pH value of the paper after deacidification is not stable and consistent, and the quality of deacidification is difficult to guarantee
