Technical Field

[0002] Various water sources in nature generally contain a certain concentration of silicon. Silicon generally exists in water in the form of soluble silicon and colloidal silicon. Colloidal silicon generally exists in the form of SiO2, and soluble silicon generally exists in the form of silicates. In industrial applications, many production waters have certain requirements on the silicon content in water to prevent silicon from entering the production system and affecting product quality or causing scaling, blockage and other adverse phenomena. Therefore, the removal process of silicon in water is widely used in all walks of life.
[0003] Existing silicon removal methods use both physical and chemical methods to remove silicon. Physical silicon removal uses nanofiltration membranes or RO to remove silicon from water through membrane interception and concentration, which can achieve deep silicon removal, but is only suitable for silicon removal from fresh water that does not contain salt. For the saturated brine system of the chlor-alkali industry brine system, since the chlor-alkali brine system is a saturated sodium chloride solution, it is difficult to use physical methods such as nanofiltration membranes or RO to remove silicon under high salt conditions. The commonly used chemical silicon removal will bring in a large amount of impurities such as aluminum, iron, calcium and magnesium, which will deteriorate the quality of the brine. Therefore, there is an urgent need for a brine silicon removal device to reasonably, efficiently and deeply remove silicon from the brine. Utility Model Content
