In the chemical industry, spray drying is a common process used to convert liquid raw materials into products in powder or granular form. However, traditional spray dryers produce a large amount of organic solvent emissions during operation, which not only wastes resources, but also pollutes the environment. In order to solve this problem, the nitrogen closed-circuit circulation spray dryer came into being, which can effectively ** organic solvents, reduce production costs, and protect the environment at the same time.
The working principle of the nitrogen closed-loop spray dryer is to mix organic solvents and raw materials together, atomize the mixed liquid into tiny droplets through an atomizer, and then dry them at high temperatures. The dried solid particles and nitrogen are fed into the cyclone separator, where the solid particles are separated and collected, while the nitrogen is recycled. In this process, the organic solvent is concentrated and collected and can be reused, resulting in the ** of the organic solvent.
Compared with traditional spray dryers, nitrogen closed-circuit circulation spray dryers have the following advantages:
1.High rate of organic solvents**: Thanks to the use of cyclones and high-efficiency filters and other equipment, the nitrogen closed-circuit circulation spray dryer can completely separate organic solvents and solid particles, so as to achieve high efficiency of organic solvents**. The rate can reach more than 99%, which greatly reduces the production cost and resource waste.
2.Good environmental performance: Because the organic solvent has been effectively reused, the emission of the nitrogen closed-loop spray dryer is greatly reduced, thereby reducing the pollution to the environment. In addition, the equipment is equipped with an exhaust gas treatment device, which further reduces the emission of exhaust gas.
3.High production efficiency: Due to the use of efficient drying technology and optimized process flow, the production efficiency of nitrogen closed-loop spray dryer is greatly improved. At the same time, the equipment also has the characteristics of high degree of automation and easy operation, which can significantly reduce labor costs and production cycles.
4.Wide range of applications: Nitrogen closed-loop circulation spray dryer is suitable for the ** and reuse of a variety of organic solvents, such as alcohols, ketones, esters, etc. In addition, the equipment can also be used in medicine, food, chemical industry and other fields, with a wide range of application prospects.
In short, nitrogen closed-loop spray dryer is an efficient, environmentally friendly and energy-saving spray drying equipment, which can achieve efficient ** and reuse of organic solvents. With the continuous improvement of environmental awareness and the construction of a resource-saving society, nitrogen closed-circuit circulation spray dryers will be more widely used and promoted.
