The purification project has been very hot in recent years, and has played an important role in various industries, escorting the environment of production sites in all walks of life. So it is necessary for us to know what the purification principle of purification engineering is and what purification technologies are commonly used in purification engineering.
Purification Project
Purification engineering includes clean room building decoration system, purification air conditioning system, water system, electrical system, gas system, etc. It can effectively control the temperature, humidity, illumination, cleanliness and static electricity in the purification workshop, so as to meet the requirements of the purification process. The working principle of air purifier in purification engineering is classified into active purification type and filter-free type. According to the active sterilization principle of these products, they can be divided into silver ion technology, negative ion technology, low temperature plasma technology and photocatalyst technology.
The working principle of the purification project is that the air is pumped into the machine by a fan and filtered through the built-in filter. It can mainly filter dust, odor, toxic gas and kill some bacteria. The filters can be divided into dust collecting filters, formaldehyde removing filters, deodorizing filters, HEPA filters, etc. Among them, HEPA filter is the most expensive one. It can decompose toxic gases and kill bacteria, especially restrain secondary pollution. The characteristics of this kind of products are that the function of fan and the quality of filter screen determine the purification effect, the placement of machine and indoor layout affect the purification, the indoor purification effect is not balanced, and it is difficult to complete, and the replacement cost of filter screen is high.
First Generation: Silver Ion Purification Technology for Purification Engineering
Simply put, the silver block is ionized into the air to play a bactericidal effect. The disadvantage of the product is high cost, low bactericidal rate and almost no viral killing characteristics.
Second Generation: Purification Engineering Ion Technology
The main principle is to use static electricity to release negative ions, absorb dust in concentrated air, and at the same time, negative ions can ionize oxygen into ozone in the air, which has a certain killing effect on bacteria. The advantages of this kind of products are lower production cost.
Third Generation: Thermal Plasma Technology for Purification Engineering
The main principle is that the gas is broken down by applying an applied voltage to the discharge voltage of the gas, producing various low-temperature plasma with strong oxidation, and contacting it in a very short time. Purification engineering has obvious and most effective effect in improving product quality. According to the reports of foreign literatures, the products manufactured in grade 1000 and l00 clean rooms are tested by withstanding voltage, and the transistor coating diffusion is carried out in grade l00 clean rooms and outdoor atmospheric environment. The performance distribution of products in Grade 100 clean rooms is concentrated. Peaks occur at higher performance locations. In the atmospheric environment, the performance of products is very dispersive and unstable.
