Solvent purifier for pretreatment of gelling

Abstract

A solvent purifying apparatus capable of preprocessing cement comprises an incinerator, a gas introducing pipe connecting the incinerator with a dryer for immersing and drying, and a filtering device arranged at the gas introducing pipe and inside provided with a filtering material and an emulsion sprinkler. According to the solvent purifying apparatus, a shape-fixing agent contained in a to-be processed volatile organic solvent exhaust gas is cemented to the filtering material, and the emulsion sprinkler sprays the emulsion to the filtering material for emulsifying and dispersing the curing agent cement. The solvent purifying apparatus is used to solve the problem that an incinerator must be frequently subjected to heat baking in the prior art, and has the efficacy of substantially reducing incinerator heat baking and substantially reducing scraping frequency on cements on pipes and valves.

Description

technical field [0001] The invention relates to a purification device, in particular to a solvent purification device capable of pre-treating gelling. Background technique [0002] Electronic devices are developing in the direction of thinner and smaller, and printed circuit boards are an indispensable component of electronic devices. Of course, they must also develop in the direction of miniaturization and high density; moreover, the copper foil substrate of flexible circuit boards It is divided into single-sided copper foil substrate and double-sided copper foil substrate. Compared with single-sided copper foil substrate, double-sided copper foil substrate can form more lines in the same space, so double-sided copper foil substrate is the main inner base material. [0003] Second, such as " figure 1 "As shown, the preparation of the copper foil substrate basically provides a non-woven fabric impregnated with resin through the impregnation tank 10, and dries the impregnat...

AI Technical Summary

Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, and provide a solvent purification device that can pre-treat the gel, so as to solve the problems of the prior art that the entire line must be kept warm and the incinerator must be heated frequently. It has the effect of greatly reducing the heating frequency and time of the incinerator, and reducing the generation of a large amount of black smoke and odor; it has the effect of greatly reducing the frequency of pipe valve glue scraping; it has the effect of avoiding smoldering and tempering to the impregnated drying machine
