Description

Novel continuous melting material melting equipment
Technical Field
The invention relates to the technical field of chemical equipment, in particular to novel continuous melting and material melting equipment.
Background
Silicon exists in nature mainly in the state of silica and silicates, all plants contain a small amount of silica, and connective tissues in the animal body also contain silica. The silicon content in the crust is absolutely abundant, with a percentage by weight of 27.6% in the crust, second only to oxygen (47.2%). Inorganic silicon compounds have been a faster developing family of inorganic chemicals in the eighties, especially more rapidly in recent years. In the class of inorganic chemicals indexed by the Derwent center patent, the patent abstracts of silicon compounds dominate absolutely. It can be seen that the inorganic silicon compounds are clearly competitive among the numerous inorganic chemicals.
In recent years, the increase in new silicon compound varieties is small, and the development of the use of inorganic silicon compounds is important. For example, the oldest variety of sodium silicates among silicon compounds is also currently being developed toward high performance and high added value; mobil corporation, USA, has developed various specifications for ZSM zeolite, almost available for various catalytic processes in petrochemical industry; silicon nitride ceramic engines are advancing to practical use. Therefore, from the current development trend, inorganic silicon compounds will be widely used in many fields such as light industry, food, medicine, construction, electronics, metallurgy, and mechanical industry, and have a great development prospect.
White carbon black is an older variety of silicon compounds, is developed in middle leaves in the thirty years, and is industrially produced in countries of Germany, Su and America and the like until the end of the forty years. The method has the advantages of late start, less varieties, poor quality, high energy consumption and no serialization in China. Therefore, the task of developing new products and developing application fields is very arduous. The production method of white carbon black is mainly two types of precipitation method and gas phase method according to the data at home and abroad. The precipitation method has the advantages of cheap and easily obtained raw materials, simpler production process and equipment and low product price, so the precipitation method is dominant at present.
The precipitation method is also called wet method, and the main raw materials are quartz sand, calcined soda, industrial hydrochloric acid or sulfuric acid or nitric acid or carbon dioxide. The process route is mainly as follows: the industrial water glass is prepared by reacting quartz sand with soda ash at high temperature by adopting fuel oil or high-quality coal, the industrial water glass is prepared into a dilute solution with a certain concentration by using water, then certain acid is added under a certain condition to precipitate silicon dioxide, and then the product white carbon black is prepared by cleaning, filtering, drying (drying or spraying) and crushing. The precipitation method includes various specific methods such as an acid method, a sol method, and a carbonization method.
Quartz sand and soda ash are calcined at high temperature in a furnace to remove impurities and are cooled by water to form industrial water glass, and the water glass is one of the main raw materials for manufacturing the precipitated white carbon black. The blocky water glass produced by the water glass kiln is melted into liquid water glass by adding water and steam under the pressure maintaining of a static pressure kettle or a melting roller (a material melting kettle) and is used in a subsequent reaction section. The water glass melted by the static pressure kettle has the advantages of good transparency, low steam consumption, low power consumption and the like. However, during the actual use of the static pressure kettle, the massive sodium silicate contains a certain amount of insoluble substances or steam pressure.
The low-time static pressure kettle can generate molten mass with a certain thickness on the upper part of the grid plate in the using process, and the solid matters easily block the grid plate, so that molten liquid water glass after being melted can not enter the bottom through the grid plate and can be discharged from the discharge pipe, and the molten mass on the grid plate can be cleaned again only after being decompressed through the vent pipe, thereby not only causing steam waste, but also influencing the productivity of equipment. Although the roller has no grid plate design, the material turning plates are distributed in the roller, the material can be turned by the rotation of the roller, the material is fully and uniformly heated and melted, the defect of a static pressure kettle is overcome, but the phenomenon of steam waste can be caused by subsequent cleaning due to the fact that the electric energy consumption is too large and part of the material is deposited in the tank body after discharging, and the small part of the capacity of the equipment is also influenced.
Both devices have a common problem: before each charging, the pressure and the temperature in the equipment are reduced to an operable state for charging, and the charging is repeated again with the previous steps: steam is added and the temperature is raised, and the process is repeated, thereby wasting a large amount of steam. Meanwhile, as the cooling and discharging are not clean, partial bottom materials are deposited at the bottom of the equipment, and when the equipment is cooled to normal temperature, the accumulated liquid can become agglomerated due to temperature reduction and subsequent feeding and liquid adding temperature rise, which causes the capacity reduction of the monomer equipment over time. When scales are beaten by external force of an air hammer, the scales cannot be completely cleaned, so that the damage to the material of the equipment body is large, and the service life of the equipment is shortened.
