We all know that the chemical industry is the general term for enterprises and units engaged in the production and development of the chemical industry. The chemical industry penetrates into all aspects. Purification processes, dyeing and finishing processes, reactor heating, etc. all require steam generators. Steam generators are mainly used for supporting chemical production. The following is an introduction to why steam generators are used in several chemical processes.
Purification process
The purification process is a very common technology in the chemical industry, so why does it need to use a steam generator? It turns out that purification is to separate the impurities in the mixture to improve its purity. The purification process is divided into filtration, crystallization, distillation, extraction, chromatography, etc. Large chemical companies generally use distillation and other methods for purification. In the process of distillation and purification, the different boiling points of the components in the miscible liquid mixture are used to heat the liquid mixture so that a certain component turns into steam and then condenses into liquid, thereby achieving the purpose of separation and purification. Therefore, the purification process cannot be separated from the steam generator.
Dyeing and finishing process
The chemical industry also has dyeing and finishing processes. Dyeing and finishing is the chemical treatment of textile materials such as fibers and yarns. The heat sources required for pretreatment, dyeing, printing and finishing processes are basically supplied by steam. In order to reduce the waste of steam heat source, the steam generated by the steam generator can be used for heating during fabric dyeing and finishing.
Steam generator for dyeing and finishing is also a chemical processing process. Fiber materials need to be washed and dried repeatedly after chemical treatment, which consumes a large amount of steam heat energy and produces harmful substances that pollute the air and water. If you want to improve steam utilization and reduce pollution during the dyeing and finishing process, you need to buy heat sources in the form of steam. However, a problem arises. These equipments can hardly directly use the high-pressure steam that has just entered the factory. The steam bought at a high price needs to be cooled down for use, which leads to insufficient steam in the machine. This has resulted in a conflicting situation where high-temperature and high-pressure steam cannot be used directly and the steam input into the equipment is insufficient, resulting in a waste of steam. However, if a steam generator is used to generate steam, the pressure controller can adjust the steam pressure according to actual production conditions. At the same time, the steam generator operates fully automatically with one click, reducing labor costs.
Supporting reactor
As a common equipment in current industrial production, reactors are widely used in food processing, pharmaceutical production, dye processing, petrochemical industry, rubber manufacturing, pesticide manufacturing and other industries. Reactors are often used in specific production processes to complete processes such as vulcanization, hydrogenation, verticalization, polymerization, and condensation of raw materials. The reactor requires a stirring device for physical change processes such as heating, cooling, liquid extraction, and gas absorption to achieve good results.
In addition, whether the reactor is heated or cooled during use, it should be carried out within a reasonable temperature difference range. Generally, the steam use temperature should be less than 180°C, the temperature difference thermal shock should be less than 120°C, and the cooling shock should be less than 90°C. This requires us to use a stable hot star source during the heating process of the reactor. In the past, coal-fired, gas-fired, and oil-fired hot water boilers were commonly used as the heat source for reactors. However, with the gradual improvement of our country's environmental protection requirements to prevent production accidents, it is best to use a steam generator to heat the reactor. Electric heating steam generator is recommended for reactor heating. Compared with oil and gas steam generators, it is environmentally friendly, energy-saving, economical, affordable, and stable.
The chemical industry is the general term for enterprises and units engaged in the production and development of the chemical industry. The chemical industry penetrates into all aspects and is an indispensable and important part of the national economy. Its development is to follow the path of sustainable development, which has important practical significance for human economic and social development.
