In chemical plants, sodium chloride evaporators are an important piece of equipment that is mainly used to process solutions containing sodium chloride. Its main function is to extract sodium chloride crystals by evaporating and concentrating the sodium chloride solution to meet the needs of industrial production.
1. The type and structure of sodium chloride evaporator.
Sodium chloride evaporators are mainly divided into two types: single-effect evaporators and multi-effect evaporators. The single-effect evaporator can only evaporate the water in the solution, while the multi-effect evaporator can evaporate the water and sodium chloride in the solution at the same time, thus improving the utilization rate of energy.
The structure of the sodium chloride evaporator is mainly composed of a heating chamber, a separation chamber, a circulating pump, a cooler, etc. The heating chamber is used to heat the solution so that the water in the solution can evaporate. The separation chamber is used to separate the evaporated water from the sodium chloride crystals. The circulating pump is used to circulate the solution between the heating chamber and the separation chamber. The cooler is used to cool the cooling water of the circulating pump.
Second, the working principle of sodium chloride evaporator.
The working principle of the sodium chloride evaporator is mainly to use the heating method to evaporate the water in the solution, leaving sodium chloride crystals. Specifically, the solution containing sodium chloride is heated through a heating chamber so that the water in the solution evaporates, leaving sodium chloride crystals. The sodium chloride crystals are then separated and dried to obtain the final product.
3. Advantages of sodium chloride evaporator.
The advantages of sodium chloride evaporator are mainly as follows:
1.The water and sodium chloride in the solution can be evaporated at the same time, which improves the utilization rate of energy
2.A high concentration of sodium chloride solution can be obtained to meet the needs of industrial production
3.It is easy to operate, easy to maintain, and has a long service life.
Fourth, the application range of sodium chloride evaporator.
Sodium chloride evaporators are widely used in chemical, pharmaceutical, food and other fields. For example, in the chemical field, sodium chloride evaporators can be used to produce chlor-alkali, fertilizers, pesticides and other chemical products;In the pharmaceutical field, sodium chloride evaporators can be used to produce drugs and reagentsIn the food field, sodium chloride evaporators can be used to produce food additives such as salt, soy sauce, and monosodium glutamate.
In short, the sodium chloride evaporator is one of the indispensable and important equipment in the chemical plant, which can extract sodium chloride crystals by evaporating and concentrating the sodium chloride solution to meet the needs of industrial production. At the same time, it also has the advantages of high energy utilization, simple operation and convenient maintenance, and is widely used in chemical, pharmaceutical, food and other fields.
