Low-temperature evaporation and concentration equipment has been more and more widely studied and applied because of its special performance and wide application, especially in chemical, food, pharmaceutical and other industries. The principle is mainly to achieve high-efficiency separation and concentration of substances by reducing the temperature and reducing the loss of thermal volatilization. This article will introduce in detail the principle, characteristics, and application of Yujia environmental protection low-temperature evaporation and concentration equipment.
1. The working principle of low-temperature evaporation and concentration equipment
The low-temperature evaporation and concentration equipment mainly uses the characteristics that the saturated vapor pressure of water is much lower than that of other components under low temperature conditions, so as to realize the separation of water and other components in the material. Its working principle mainly includes the following steps:
Evaporation:By reducing the operating pressure, the moisture in the material boils at low temperatures and is converted into water vapor.
Condensation:Water vapor is condensed through a condenser to convert it into liquid water.
Separation:Due to the different physical properties of water and other components in the material, they are effectively separated during evaporation and condensation.
Concentrate:The separated water and other components are further processed to obtain a concentrate of the desired concentration.
2. Characteristics of low-temperature evaporation and concentration equipment
Low-temperature evaporation and concentration equipment has the following characteristics:
Low temperature operation:Due to the low-temperature operation, the energy consumption of the equipment is low, while the corrosion and fouling problems on the equipment are reduced.
High heat transfer efficiency:The heat transfer coefficient of the low-temperature evaporation concentration equipment is high, which is conducive to increasing the production capacity of the equipment.
Good separation:Due to the low temperature operation, the boiling point difference between the different components is expanded, resulting in better separation of the substances.
Wide adaptability:It is suitable for a variety of materials with different properties, and its application field is very wide.
Environmental protection and energy saving:It does not generate a large amount of waste heat in the production process, so it has a good environmental protection and energy saving effect.
3. Application of low-temperature evaporation and concentration equipment
Low-temperature evaporation and concentration equipment is widely used in many fields, and here are a few examples:
Chemical industry:In the chemical industry, it is mainly used to produce high-purity, high-value-added chemical products. For example, aromatic hydrocarbon compounds can be concentrated by low-temperature evaporation and concentration equipment to produce high-purity paraxylene. In addition, low-temperature evaporation and concentration equipment can also be used to prepare chemical products such as high-purity inorganic salts.
Food Industry:In the food industry, it is mainly used for the concentration of liquid foods such as fruit juices, syrups, sauces, etc. Because low-temperature operation can retain nutrients and flavor substances in food, low-temperature evaporation and concentration equipment is widely used in the food industry. In addition, the low-temperature evaporation and concentration equipment can also be used to prepare food products such as low-confectionery jams and jellies.
Pharmaceutical industry:In the pharmaceutical industry, it is mainly used for the preparation of high-concentration pharmaceutical solutions and pharmaceutical intermediates. Due to the good separation effect of low-temperature evaporation and concentration equipment, the resulting product has high purity, so it is widely used in the pharmaceutical industry. In addition, the low-temperature evaporation and concentration equipment can also be used for waste liquid treatment and **.
Other areas:Low-temperature evaporation and concentration equipment is also widely used in other fields, such as in the field of environmental protection for the treatment of waste liquid containing heavy metal ions, in the field of energy for the use of fresh water in geothermal power plants**, etc.
Low-temperature evaporation and concentration equipment is a kind of high-efficiency, energy-saving and environmentally friendly separation and concentration equipment, which has been widely used in chemical, food, pharmaceutical and other industries. Its working principle is mainly to achieve high-efficiency separation and concentration of substances while reducing thermal volatilization losses by reducing the temperature. Its advantages include low temperature operation, high heat transfer efficiency, good separation effect, strong adaptability, environmental protection and energy saving, etc. In practical application, the low-temperature evaporation and concentration equipment has high production efficiency and product quality stability, and the quality and purity of the obtained products are high, and it has good market prospects and development potential. With the continuous development of science and technology and the continuous upgrading of industrial production, the technical level of low-temperature evaporation and concentration equipment will continue to improve, and its application field will continue to expand.
