Embodiment 1

[0024] A kind of production method of liquid sodium silicate, described method comprises the following steps:

[0025] A. Raw material preparation: mix quartz sand and sodium carbonate in a ratio of 3:1 by weight;

[0026] B. Melting: Add the quartz sand and sodium carbonate mixed in step A into a kiln with a temperature of 1300° C. for melting, and the melting time is 3 minutes to obtain the reaction material;

[0027] C, cooling: the reaction material obtained in step B is cooled on a chain plate machine with a cooling water device, and the reaction material is cooled to 300 ° C;

[0028] D. Dissolving: Put the reaction material cooled to 300°C in step C into the dissolution furnace, then add water according to the ratio of reaction material to water weight ratio of 2:1, and then increase the steam pressure of the dissolution furnace to 0.6MPa, Dissolved into a liquid reaction material;

[0029] E. Filtration: Put the liquid reaction material obtained in step D into the pr...

Embodiment 2

[0032] The difference from Example 1 is the raw material preparation of step A: mixing quartz sand and sodium carbonate at a weight ratio of 3.5:1. The calcination temperature in step B is 1350°C.

Embodiment 3

[0034] The difference from Example 1 is the raw material preparation of step A: mixing quartz sand and sodium carbonate at a weight ratio of 4:1. The calcination temperature in step B is 1400°C.

[0035] The liquid sodium silicate prepared by the method of the present invention and the liquid sodium silicate prepared by the prior art are detected and analyzed, and the comparison of the detection and analysis is shown in the following table:

[0036] group

[0037]According to the above table, the detection of chroma, water-insoluble content and suspended solids of the liquid sodium silicate produced by the inventive method is obviously better than the prior art, which fully shows that the inventive method is better than the liquid sodium silicate prepared by the prior art Good clarity, good transparency, more thorough filtration and better purity.

Abstract

A production method of liquid sodium silicate comprises steps as follows: A, raw material preparation; B, melting; C, cooling; D, dissolution; E, filtration; F, collection. Quartz sand used in production of sodium silicate is used as a filter aid for a blade filter, and quartz sand carrying impurities after cleaning returns to the production of solid sodium silicate again to be used as a raw material. With the adoption of the method, other filter aids are not required to be purchased specifically, and the raw material for production of the sodium silicate is used as the filter aid and returns to the production of the solid sodium silicate after being used, so that the purchasing cost of the filter aid cannot be increased, waste cannot be produced, and the environmental pollution is avoided. The liquid sodium silicate prepared with the method is high in transparency, good in stability, low in impurity content and good in clarity.

Description

technical field [0001] The invention belongs to a production method of sodium silicate, in particular to a production method of liquid sodium silicate. Background technique [0002] At present, the filtration methods in the production process of liquid sodium silicate can be roughly divided into centrifugal separation, plate and frame filter press filtration, closed blade filter filtration and other methods. The amount of centrifugal separation is too small, so the current large-scale production filtration methods generally adopt two methods: plate-and-frame filter press filtration and closed leaf filter filtration. [0003] The closed leaf filter currently uses diatomaceous earth as a filter aid, and a layer of filter aid is coated on the blade of the leaf filter as a filter coating, and liquid sodium silicate is made of filter aid. When coating, the suspended solids and particulate impurities in the liquid sodium silicate are isolated on the coating made of filter aid. Wh...
