Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.

Separation technology is an extremely widely used technology, applicable to pharmaceutical, chemical, metallurgy, textile, environmental protection, food, military and other industries, it is to promote liquid-solid, liquid-liquid or liquid-solid suspension by centrifugal force Liquid or emulsion according to the characteristics of physical properties, different separation requirements to achieve a different separation of a device, due to its simple structure, high efficiency, pure physical separation process, can fully guarantee the characteristics of the separation of materials. Therefore, the market for centrifuges is extremely broad.
As we all know, the harm of corrosion is extremely large. There are many examples in the world to illustrate that the centrifuge is a high-speed rotating device. Its safety requirements are as important as the pressure vessels. Most of the centrifuge manufacturers are designing, selecting and In the application, more consideration was given to the effect of uniform corrosion on the strength parts, and the structural design, processing technology, and other adaptations to the corrosive environment were neglected, resulting in some serious consequences. Not only does the part have a tendency to corrode, it pollutes the material being separated, and even more serious causes the machine to die.
First, the centrifuge environment
Centrifuges are divided into different types of equipment by function and structure, but they all have common features:
1, drum for high-speed rotating parts;
2, the main body of the drum constitutes a separate space;
3, drum was shaped structure;
4. There are some other connectors or accessories in the drum.
These characteristics of the drum indicate that the core part of the centrifuge is a stress piece. Its irregular geometry leads to the distribution of stress distribution of parts and the cooperation of multiple parts, which in turn makes it possible to form a pair of electric couples. This is something worth noting.
Second, the possible corrosion phenomenon
Corrosion morphology is mainly divided into two categories: uniform corrosion and local corrosion. The former is easy to find because of apparent phenomena, and it is clearly stated in most manual data. It will not be elaborated here. Only the latter is discussed.
Corrosion occurs only partially, is a very serious and harmful damage, such as pitting, crevice corrosion, intergranular corrosion, stress corrosion, wear and corrosion, etc. In the centrifuge, local corrosion is widespread, Emphasis is placed on analyzing the mechanism of its formation, taking measures and overcoming them.
Analysis of Using Environment and Instrument Protection Method of Centrifuge
In recent years, China’s national economy has continued to develop, new technologies and new technologies have emerged endlessly, and the application of centrifuges has become more widespread. However, in this process, most manufacturers are more concerned with the separation performance and strength of centrifuges. Requirements, the impact of corrosion factors are often not enough, resulting in some negative effects, this article on this issue for some analysis and explanation for everyone to discuss.
