sodium silicate plant

Sodium silicate and sodium silicate, (NaSiO3). Production method has two kinds of dry method and wet method, dry method with soda ash and quartz sand is calcined into solid sodium silicate, the film in 3.3-3.3 (SiO2 / NaO), especially suitable for production of silica (SiO2), the high energy consumption, simple device, small investment, solid transportation, solid content, low alkali consumption same dominant in the market. Also useful glauber's salt instead of soda ash, but environmental problems.

Wet method is to use quartz sand and liquid caustic soda heating pressure, filtering. Modulus is less than 2.8, suitable for use in production of silicon layer, partial silicon, etc. The low energy consumption, product is liquid, need to form a complete set of boiler, manufacturers are rare.

佰富彩Face of liquid with solid liquid production is very simple, small user has regional advantages, material modulus is lower, the better, heating alkaline water transferred film.

佰富彩1. Water glass reaction kettle:

佰富彩This equipment is the main equipment for the production of sodium silicate, the use of a certain temperature (160-170 ℃) and pressure (6-10 kg/cm2) of material (usually in the form of quartz sand and aqueous solution of caustic soda or soda ash) react to generate sodium silicate products. Equipment is divided into fixed vertical and rotary reactor horizontal reaction kettle. Products are 6 kinds of specifications, volume is:

佰富彩3 M3, 5 M3, 6 M3, 8 M3, 10 M3, 12 M3, 14 M3, 15 M3, 16 M3, 18 M3, 20 M3

2. The drum of sodium silicate solution:

The device is to use a certain temperature and pressure to make the material (usually in the form of solid sodium silicate and water) to produce dissolving reaction to generate sodium silicate solution. Equipment is divided into steam heating and heat conduction oil heating type two kinds, steam heating type temperature 150 ℃ to 160 ℃, use 0.5 0.6 MPa pressure steam, thermal oil temperature 180 ℃ to 200 ℃. Products are 6 kinds of specifications, the volume is: 3 M3, 5 M3, 6 M3, 8 M3, 10 M3, 12 M3, 14 M3, 15 M3, 16 M3 18 M3, 20 M3,

Heat conduction oil type because of its low efficiency, high energy consumption, has been gradually withdraw from the market. The most used at present, the most energy-efficient is on both sides with shaft structure, heat source, using the new type of steam drum.
