Monitoring of water pollution, which is closely related to human health, is a top priority. Water is the source of life, and water pollution will directly affect the safety of people's drinking water and health. Therefore, it is important to strengthen the monitoring and control of water pollution. Through automatic monitoring technology, the water quality of the water source can be monitored in real time, and the pollution problem can be detected in time and corresponding measures can be taken to deal with it, so as to ensure the safety of people's drinking water.
The chemical oxygen demand digestion device is an important equipment used to determine the chemical oxygen demand in water samples. In the process of COD determination, it is necessary to react the water sample with the oxidant under specific conditions, and the digestion device is the equipment that provides this reaction environment. Traditional digestion units usually use spherical reflux tubes for cooling, but now some new digestion units use glass burr reflux tubes instead of spherical reflux tubes, and use air-cooled plus water-cooled technology to replace the traditional tap water cooling methods.
The design of the glass burr return tube can effectively increase the contact area between the water sample and the cooling water, thereby improving the cooling efficiency. At the same time, the burr structure also prevents the formation of limescale in the return pipe, ensuring the durability of the cooling effect. This design not only improves the cooling efficiency of the digestion unit, but also extends the service life of the unit.
In addition, the use of air-cooled and water-cooled technology can reduce the temperature of the digestion unit more quickly, thereby shortening the digestion time and improving the measurement efficiency. At the same time, this technology can also avoid the water quality problems and environmental risks associated with the use of tap water.
In the cooling part, the combination of burr condenser tube and dual fan can form a powerful cooling effect. The burr condenser tube improves cooling efficiency by increasing the contact area and burr structure, while the dual fans can provide more air volume and speed up the cooling rate. In addition, the dual effect of the cooling water in the upper spherical return tube and the fan in the machine can further ensure the reflux cooling effect of the sample.
Chemical oxygen demand digestion devices with glass burr reflux tubes and air-cooled plus water-cooled technology have higher cooling efficiency and measurement efficiency, while avoiding some of the shortcomings of traditional methods. The application of this new digestion device will help to improve the accuracy and reliability of COD determination, and provide better technical support for environmental protection and water quality monitoring.
