Process for synthesizing high-quality sodium silicate with low energy consumption

Abstract

The invention discloses a process for synthesizing high-quality sodium silicate with low energy consumption, aims to solve the problems of high energy consumption and poor product quality of an existing process for producing sodium silicate, and relates to the technical field of processes for producing sodium silicate. The process for synthesizing high-quality sodium silicate with low energy consumption comprises the following steps of: connecting a soft water necessary device of a gas producer with a blast blower, wherein water gas produced by the gas producer sequentially passes through a cyclone dust collector, an exchanger and a heat storage chamber, and the heat storage chamber is provided with an interlayer which is connected with a waste heat pipe of the gas producer; performing heat preservation on the heat storage chamber by using the waste heat of the gas producer; directly introducing the water gas in the heat storage chamber into a smelting kiln for burning; introducing molten sodium silicate produced by the smelting kiln into a clarifying and precipitating tank for purification and precipitation; and then putting the molten sodium silicate into a discharging machine through a chute so as to be in contact with circulating water, and packaging after cooling. According to the process, the gas supply is more stable, the water gas is preheated before entering the smelting kiln for burning, the coal consumption can be saved, and the sodium silicate is purified and precipitated, so that the product quality is improved.

Description

Technical field: [0001] The invention relates to the technical field of sodium silicate production technology, in particular to a process for synthesizing high-quality sodium silicate with low energy consumption. Background technique: [0002] Sodium silicate is commonly known as water glass, and its main component is silicon. [0003] Sodium silicate has a wide range of uses, covering almost all sectors of the national economy. In the chemical system, it is used to manufacture various silicate products such as silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, layer silicon and instant powdered sodium silicate, potassium sodium silicate, etc. Basic raw material for silicon compounds. In economically developed countries, more than 50 kinds of deep-processing products using sodium silicate as raw materials have been developed, some of which have been used in high-tech, fine-tech fields; in light industry, it is an indispen...
