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:
The present invention relates to the water glass technical field of producing, relate in particular to the technology of the synthetic high-quality water glass of a kind of less energy-consumption.
Background technology:
Water glass is commonly called as water glass, and main component is silicon.
The purposes of water glass is very extensive, almost spreads all over each department of national economy.Being used to make various silicates products such as silica gel, white carbon black, zeolite molecular sieve, metasilicate pentahydrate sodium, silicon sol, layer silicon and instant powdery sodium silicate, sodium-potassium silicate at chemical system, is the basic raw material of silicon compound.In developed country, be kind surplus the deep processing series product of raw material have developed into 50 with the water glass, some has been applied to the high, precision and frontier sciemtifec and technical sphere; Being indispensable raw material in the washing composition such as washing powder, soap in light industry, also is water softener, settling agent; In textile industry, be used for helping dye, bleaching and sizing; In mechanical industry, be widely used in casting, emery wheel manufacturing and anticolodal etc.; In building trade for the manufacture of rapid hardening cement, acid-proof cement dubbin, soil-solidified-agent, refractory materials etc.; Agriculturally can make the silicon element fertilizer material; Floating, dying and slurry, mine ore dressing, waterproof, leak stopping, fire retarding wood protection, food antiseptic and preparing adhesive etc. as tackiness agent, anticolodal, water-softening agent, detergent builder, refractory materials and the ceramic raw material of the filler of the silica-alumina catalyst of petroleum catalytic cracking, soap, fluting board, textiles in addition.
In the industrial production, be that quartz sand and soda ash are mixed back being heated to about 1400 ℃ by a certain percentage in Reaktionsofen, generate the molten water glass.There is the defective of energy consumption height, product quality difference in the production technique of existing water glass.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art, and the technology of the synthetic high-quality water glass of a kind of reinforced less energy-consumption easily is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
