空气净化技术一般采用哪些技术？-凯发k8手机客户端

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.

空气净化工程按原理分为乱流洁净室和层流洁净室。按应用分为工业净化工程，生物净化工程。空气净化程是一整套系统，洁净厂房设计和验收规范里就有说明。大致包括洁净室建筑装饰系统，净化空调系统，水系统、电系统、气系统等，对洁净室内的温度、湿度、照度、洁净度、静电现象进行管控，从而达到特定的工艺要求。

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.

空气净化器工作原理分类主动净化类无滤网型根据这些产品的主动杀菌原理可分为银离子技术、负离子技术、低温等离子技术、光触媒技术和净离子群离子技术。

空气净化工程的工作原理是：用风机将空气抽入机器，通过内置的滤网过滤空气，主要能够起到过滤粉尘、异味、有毒气体和杀灭部分细菌的作用。滤网又分：集尘滤网、去甲醛滤网、除臭滤网、hepa滤网等。其中成本比较高的就是hepa滤网，它能起到分解有毒气体和杀菌作用，特别是抑制二次污染。这类产品的特点是风机功能以及滤网的质量决定净化效果，机器的放置以及室内布局影响净化是否完全，室内净化效果不均衡，也难以完全，滤网更换费用较高。

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.

代：银离子净化技术

the first generation: silver ion purification technology

简单地说就是把银块离子化吹到空气中以起到杀菌的效果缺点产品成本高，细菌杀灭率低，对病毒几乎没有杀灭特性。

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.

第二代：离子技术

second generation: ion technology

主要原理是运用静电释放负离子，吸附集中空气中的粉尘起到降尘作用，同时负离子对空气中的氧气也有电离成臭氧的作用，对细菌有一定的杀灭作用，这类产品优点是产品生产成本较低。

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.

第三代：温等离子技术

the third generation: warm plasma technology

主要原理是，通过给气体外加电压至气体的放电电压，使气体被击穿，产生各种强氧化性的低温等离子，并在极短时间内把接触。

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.
