Technical Field
The invention belongs to the field of water glass production equipment, and particularly relates to a device for recycling water for soaking and cleaning soybeans and a production process thereof.
Background
Sodium silicate, synonymous to sodium silicate, is an inorganic substance of the chemical formula Na2SiO3The aqueous solution is called water glass, colorless, greenish or brown solid or viscous liquid. The sodium silicate is prepared by co-melting silica (quartz sand) and soda ash (or soda-lime) in a melting furnace, cooling and pulverizing, and the fuel can be coal, natural gas or coal gas.
The raw materials for producing the sodium silicate are quartz sand and sodium carbonate, the quartz sand and the sodium carbonate are mixed according to a certain proportion and sent to a reflecting kiln, and the solid sodium silicate is obtained after water quenching in a high-temperature calcining and dissolving furnace. The solid sodium silicate is favorable for transportation and storage. The solid sodium silicate is dissolved into liquid at a certain temperature and pressure, and the liquid sodium silicate is obtained.
The preparation process comprises the following steps: quartz sand, soda → mixing → calcining → water quenching → solid sodium silicate → melting → liquid sodium silicate.
The production process of sodium silicate can be divided into a dry method and a wet method, wherein the dry method is generally used for producing solid sodium silicate, and the solid sodium silicate is dissolved and converted into liquid sodium silicate with the required specification, and the conversion rate is 1: 2.5.
The dry production is that quartz sand and sodium salt (mainly Na2CO3 and Na2SO4) are stirred uniformly and melted and reacted at the high temperature of about 1400 ℃. The method is divided into a soda process and a mirabilite process according to different raw materials. The production process comprises four procedures of material preparation, calcination, leaching, concentration and the like. The specific process is as follows:
firstly, the method comprises the following steps: material preparation and melting: the sodium carbonate or the mirabilite and the quartz sand are uniformly stirred by a stirrer and then added into a reverberatory furnace or a horseshoe flame furnace by a spiral conveyer through a storage tank and a charging hopper for carrying out melting reaction.
II, secondly: leaching: when raw materials are added into the melting furnace, molten water glass can flow into a cooling tank from a feed opening, the molten water glass is conveyed into a storage barrel through a small crawler-type conveyor, after weighing, glass blocks in the barrel are lifted by an electric travelling crane and poured into a roller, appropriate amount of water is added according to the weight of the blocks and different product specifications, steam is introduced for dissolution, the steam pressure is generally 0.4-0.5 MPa, the rotating speed of a liquid cylinder is 2-4 r/min, the glass blocks are dissolved to a certain concentration and then are placed into a settling tank, and impurities are removed through natural settling.
Thirdly, the method comprises the following steps: concentration: and (3) conveying the solution after the impurities are removed into a concentration tank for concentration, indirectly heating by adopting steam, heating the tank bottom by utilizing the residual heat of the flue gas of the melting furnace, and concentrating the solution to the required concentration to obtain a finished product.
The wet process for producing sodium silicate is divided into the traditional wet process and active SiO2Two normal pressure production processes. The production principle of the traditional wet method is that quartz sand is dissolved in high-temperature caustic soda to generate sodium silicate. Active SiO2Normal pressure production process active SiO2The normal pressure production of sodium silicate is a new process developed in the three-waste treatment process in recent years, and a few manufacturers adopt the method, and the method can produce any product with the modulus of 2.2-3.7. The mechanism is to utilize the active SiO in the by-product or leftover generated in industrial production2(or silica gel) is heated under normal pressure to react with caustic soda to generate sodium silicate. The reaction equation is the same as that of the conventional wet process.
At present, when the water glass is produced by a wet method, liquid sodium hydroxide and quartz sand are mixed according to a proper proportion and added into an autoclave, and the mixture is heated by steam and stirred to directly react to form liquid sodium silicate.
