Brine refining device conducting filtering step by step

Abstract

The invention relates to an ionic membrane caustic soda brine device, in particular to a brine refining device conducting filtering in four steps. The brine refining device comprises a brine barrel, a brine baffling groove, a first-stage brine filter, a rough brine groove and brine filters. The brine barrel is connected with the first-stage brine filter through the brine baffling groove, the first-stage brine filter is connected with the rough brine groove which is connected with the second-stage brine filter, the second-stage brine filter is connected with a brine reaction barrel which is connected with the third-stage brine filter, the third-stage brine filter is connected with the fourth-stage brine filter, and the fourth-stage brine filter is connected with a fine brine groove. Compared with the prior art, the brine refining device has the advantages that the multiple stages of step-by-step filtering devices are adopted, the refining degree is high, the refining cost is reduced, the arrangement of baffle plates is improved, the baffling effect is greatly improved, and the application effect is good.

Description

technical field [0001] The invention relates to an ion membrane caustic soda brine refining device, in particular to a step-filtering brine refining device. Background technique [0002] At present, the market of chlor-alkali industry is sluggish. In order to cope with the current environment, chlor-alkali enterprises can only start from the inside, improve product quality, reduce production costs, and improve the market competitiveness of enterprise products. When the ion-exchange membrane electrolyzer adopts new technology to reduce power consumption, the cost of raw materials can be reduced, and raw salt with slightly lower quality can be used for production, which increases the difficulty of refining brine. In the process of preparing refined brine, there are various impurities, such as the inconsistency of filtration accuracy, which directly leads to unqualified brine quality, and further filtration is required, which increases production and operation costs.
