The present invention discloses a sodium silicate energy-saving preparing process, the sodium silicate energy-saving preparing process is simple, solid sodium silicate and liquid sodium silicate can be produced, during the production energy can be effectively saved, resource investment of heating of the solid sodium silicate is reduced, resource utilization rate is improved, sodium silicate production quality is improved, and the produced solid sodium silicate has consistent quality.
Description
Technical field
The invention belongs to technical field of inorganic chemical industry, be specifically related to the energy-conservation preparation technology of a kind of sodium silicate.
Background technology
Water glass (Na
2si0
2), have another name called sodium silicate, water glass (XNa
20.YSi0
2), colourless, dark green or brown solid or thick liquid, sodium silicate purposes widely, almost throughout each department of national economy, be used for manufacturing silica gel, white charcoal ?, zeolite molecular sieve, Starso silicon sol, layer silicon and instant powdery sodium silicate at chemical system, the various silicates product such as sodium-potassium silicate is the basic raw material of silicon compound, being indispensable raw material in the lotion such as washing powder, soap in light industry, is also the light agent of water quality, washing assistant, for helping dye, bleaching and sizing in textile industry, casting, emery wheel manufacture and anticolodal etc. are widely used in machinery industry, for the manufacture of rapid hardening cement, acid-proof cement dubbin, soil-solidified-agent, refractory materials etc. in building trade, in addition, as tackiness agent, Si0 is used in medical
2refine, non-phosphorus builder best at present, in prior art, the production method of sodium silicate mainly contains two kinds, dry method and wet method respectively, in dry production, soda ash and quartz sand raw material are at high temperature carried out igneous fusion, solid sodium silicate is after shaping, water-soluble after water extraction, i.e. obtained product, in wet production, normally heat in the stove of cellar for storing things, raw material is melted in the stove of cellar for storing things, and heated by coal, then cool, the solid sodium silicate obtained is through certain temperature, Pressure Melting becomes liquid to be liquid sodium silicate, manufacture craft traditional like this, production efficiency is not high, and when the melting of solid sodium silicate is liquid sodium silicate, need to carry out high-temperature steam heating before melting to it, such manufacture craft energy consumption is higher, waste water resource and a large amount of energy consumption, and the quality of producing the solid sodium silicate obtained can not as one owing to mixing reason.
Summary of the invention
The object of this invention is to provide the energy-conservation preparation technology of a kind of sodium silicate, present method technique is simple, effectively can save energy consumption, improves resource utilization, promotes sodium silicate production quality.
In order to solve the problem existing for background technology, the present invention by the following technical solutions:
The energy-conservation preparation technology of a kind of sodium silicate, includes following steps:
1. filtration chosen by material: raw material quartz sand, soda ash are filtered through sodium silicate screen apparatus respectively, and deposited respectively by the material after filtering;
2. material melts: quartz sand conveying the first reactor be placed in heating chamber after filtering is melted, and the quartz sand after fusing is imported in the second reactor in heating chamber, the soda ash after filtration is added to its inside by the top of the second reactor, adding quartz sand weight ratio in soda ash and the second reactor is 1:2, the stirring mechanism of the second reactor inside stirs mixing raw material, the indoor pressure of heating chamber remains on 400-800Pa, and to water filling in heating chamber, makes steam water voltage rise high;
3. discharging: blowing is carried out to the liquid sodium silicate that the second reaction kettle for reaction obtains completely, export the feeding-distribution device in discharge port lower end, the mould being transported to rotation by feeding-distribution device is shaped, water cycle crushed aggregates device is provided with above mould, cooling shrend can be carried out to the sodium silicate in mould, solid sodium silicate after shrend carries out intensification heating via heating steam in heating chamber, then the solid sodium silicate heated through high-temperature steam is carried out melting, obtains liquid sodium silicate.
Beneficial effect of the present invention: present invention process is simple, solid sodium silicate, liquid sodium silicate can be produced, effectively energy consumption can be saved during production, decrease the resource input to the heating of solid sodium silicate, improve resource utilization, promote sodium silicate production quality, produce the quality of the solid sodium silicate obtained as one.
