空气净化 技术实现 一般采取应用哪些 技术实现 ？
In a certain space, the purification project will remove the particles, harmful air, bacteria and other pollutants in the air, and control the indoor temperature, cleanliness, pressure, air velocity and air distribution, noise, vibration, lighting and static electricity within a certain demand range. No matter how the external air condition changes, the rooms specially designed for the purification project have the performance of maintaining the cleanliness, temperature, humidity and pressure as originally set.
According to the principle, the air purification project is divided into turbulent clean room and laminar clean room. According to the application, it can be divided into industrial purification engineering and biological purification engineering. The air purification process is a complete system, which is described in the design and acceptance specification of clean workshop. It mainly includes the decoration system of clean room, purification air conditioning system, water system, electricity system, gas system, etc. it controls the temperature, humidity, illumination, cleanliness and electrostatic phenomena of clean room, so as to meet the specific process requirements.

The working principle of air purifier is classified into active purification type without filter screen. According to the active sterilization principle of these products, it can be divided into silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group ion technology.
The working principle of the air purification project is: use the fan to pump the air into the machine and filter the air through the built-in filter screen, which can mainly filter the dust, peculiar smell, toxic gas and kill some bacteria. Filter screen is divided into: dust collection filter screen, formaldehyde removal filter screen, deodorization filter screen, HEPA filter screen, etc. One of the high cost is HEPA filter, which can decompose toxic gas and sterilize, especially inhibit secondary pollution. The features 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 whether the purification is complete, the indoor purification effect is not balanced, and it is difficult to complete, and the replacement cost of filter screen is high.
The first generation: silver ion purification technology
In short, it is to blow the silver block ionization into the air to have a bactericidal effect. However, the product cost is high, the bactericidal rate is low, and there is almost no killing characteristic for the virus.
Second generation: ion technology
The main principle is to use static electricity to release negative ions, absorb and concentrate the dust in the air and play a role in dust reduction. At the same time, negative ions can also ionize the oxygen in the air into ozone and kill bacteria to a certain extent. The advantage of such products is that the production cost is low.
The third generation: warm plasma technology
The main principle is that the gas is broken down by applying voltage to the discharge voltage of the gas, producing various kinds of low-temperature plasma with strong oxidation, and contacting in a very short time.
