Abstract

The invention provides an improved method and device for high-modulus water glass solid static pressure dissolution. The method is dissolved by adopting one feeding and three times of adding steam to dissolve; There are strict requirements on process parameters such as pressure holding time and pressure holding time. These parameters effectively solve the problems of silting at the bottom of the autoclave, sticking and blocking of sieve plates, incomplete dissolution, and low dissolution yield during the production process of the static autoclave; Through the external balance valve, the internal balance pipe, and the double balance device group, the pressure on the sieve plate in the kettle can be effectively consistent, and the pressure of the pipeline inside and outside the kettle is consistent, so as to avoid deformation of the sieve plate caused by blockage during the production process. Problems such as equipment failure caused by the collapse of the sieve plate.

Description

technical field [0001] The invention relates to the technical field of water glass preparation, in particular to an improved method and device for hydrostatic dissolution of high modulus water glass solids. Background technique [0002] Water glass, commonly known as sodium silicate, is a water-soluble silicate, and its aqueous solution is commonly known as water glass. Sodium silicate (Na 2 O nSiO 2 ) aqueous solution is used in the chemical system to manufacture various silicate products, and is the basic raw material of silicon compounds. There are many varieties of deep-processing products based on sodium silicate, some of which have been used in high-tech, fine-tech fields; they can also be used as detergent raw materials, water softeners, sedimentation aids, dyeing aids, bleaching, sizing, Foundry, soil stabilizer, manufacture of silicon fertilizer, etc. [0003] The chemical formula of water glass is R 2 O nSiO 2 , where R 2 O is an alkali metal oxide, and n is...
