空气净化器原理解析。

Analysis of the principle of air purifier.

空气净化器逐渐成为继电视、冰箱、洗衣机和空调后的又一主要家电设备，但很多消费者对于空气净化器仍处于一知半解的状态，所以今天不如花点时间了解一下空气净化器原理，这样不仅自己掌握了知识，对于什么样的空气净化器好也心知肚明。

Air purifier is gradually becoming another major appliance after TV, refrigerators, washing machines and air conditioners, but many consumers are still in a half - understanding state of air purifier. So it is better to spend some time today to understand the principle of air purifier. So not only do you know what kind of air you have, but also what kind of air you have. The purifier is well - aware.

目前市场上主流的空气净化器的工作原理主要以下几种：

At present, the mainstream air purifiers on the market mainly work on the following principles:

第一种是被动吸附过滤式的空气净化原理。

The first is the principle of passive adsorption and filtration of air purification.

被动式的空气净化，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、消毒等作用。这种滤网式空气净化器多采用HEPA滤网+活性炭滤网+光触媒(冷触媒、多远触媒)+紫外线杀菌消毒+静电吸附滤网等方法来处理空气。其中HEPA网HEPA(High efficiency particulate airFilter)，中文意思为高效空气过滤器，HEPA网的特点是空气可以通过但细小的微粒却无法通过。HEPA过滤网由连续前后折叠的亚玻璃纤维膜构成，形成波浪状垫片用来放置和支撑过滤界质。注意：HEPA的作用是在净化器中起到至关重要的作用，一块好的HEPA滤网决定了空气净化器的好坏，如Blueair的SmokeStop™除烟去味复合滤网，配备上Blueair特有的HEPASilent技术，使进入净化机的微粒带电、过滤网本身是高效低风阻材料，再加上先进的进出风口设计，这样过滤网就能以较低的空气阻力来过滤大量的空气污染物，包括甲醛、tVOC、苯等各种有害化学气体及异味，还确保了Blueair实现室内空气净化系统的“两低一高”：低风阻、低噪音，高效率。低速档运行时高效轻音，让用户在宁静中呼吸清新纯净的空气。

The passive air purification is to use the fan to pump the air into the machine and filter the air through the built-in filter. It can play the role of filtering dust, odor and disinfection. The filter type air purifier uses HEPA filter net + active carbon filter + Photocatalyst (cold catalyst, multi far catalyst) + ultraviolet sterilization and electrostatic adsorption filter net to treat air. The HEPA network HEPA (High efficiency particulate airFilter), the Chinese meaning of the efficient air filter, the HEPA network is characterized by the air can pass but fine particles can not be passed. HEPA filters consist of a continuous front-and-back folded submerged fiberglass membrane, forming a wavy gasket for placing and supporting the filtration boundary. Note: the role of HEPA plays a vital role in the purifier, and a good HEPA filter determines the quality of the air purifier, such as Blueair's SmokeStop de smoked compound filter, and Blueair specific HEPASilent technology to make the particles into the purifier with electricity, the filter network itself is a high efficiency and low resistance material. With the advanced inlet and outlet design, the filter can filter a large number of air pollutants with lower air resistance, including formaldehyde, tVOC, benzene and other harmful chemical gases and odor. It also ensures the "two low high" of the indoor air purification system by Blueair: low wind resistance, low noise and high efficiency. Low-speed running high-efficiency soft tone, let the user breathe fresh and pure air in the quiet.

第二种工作原理是主动式的空气净化原理。

The second principle is the active air purification principle.

市场上的主动类空气净化器和双重净化类空气净化器一般只选择一种主动式的净化技术。目前市场上主要有银离子净化技术、负离子技术、低温等离子技术、光触媒技术和净离子群技术。主动式的空气净化原理与被动式空气净化原理的根本区别就在于，主动式的空气净化器摆脱了风机与滤网的限制，不是被动地等待室内空气被抽入净化器内进行过滤净化，之后再通过风机排出，而是有效、主动地向空气中释放净化灭菌因子，通过空气弥漫性的特点，到达室内的各个角落对空气进行无死角净化。

The active air purifier and double purification air purifier in the market usually only choose one kind of active purification technology. At present, there are mainly silver ion purification technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group technology in the market. The fundamental difference between the active air purification principle and the passive air purification principle is that the active air purifier is free from the limitation of the fan and filter, and is not passively waiting for the indoor air to be filtered and purified in the purifier, and then discharged through the fan, but effectively and actively releasing the air into the air. Purifying and sterilizing factors, through air diffuse characteristics, arrive at every corner of the room to purify the air without dead ends.

还有一种是厨房油烟专用净化机。

There is also a special purifier for kitchen fumes.

市面上的油烟净化器都是采用高压静电吸附原理来处理净化油烟。所以油烟净化器的内部都装有独特的油类碰吸单元。经过油烟净化器，在高压等离子电场的作用下，将微小的油颗粒与气体进行电离荷电，带电的微小粒子被吸附单元收集，比你更流入和沉积到油烟净化器的储油箱内，烟尘内的有害气体，被电场内所产生的臭氧所杀菌，并去除了异味，有害气体被除掉，油烟去除率经国家环保总局认定的监测部门检测，洁净的空气经出风口排出，达标排放。

The oil fume purifier on the market adopts the principle of high voltage electrostatic adsorption to treat the lampblack. Therefore, the inside of the lampblack purifier is equipped with a unique oil suction unit. After the oil smoke purifier, under the action of the high pressure plasma electric field, the tiny oil particles and the gas are charged and charged. The tiny charged particles are collected by the adsorption unit, which are more inflow and deposited into the tank of the oil fume purifier. The harmful gases in the smoke and dust are germicidal and removed by the ozone produced in the electric field. The odor, harmful gas is removed, the removal rate of oil smoke by the State Environmental Protection Administration of the monitoring department detected, clean air out of the tuyere, discharge standard.

油烟净化器的电场采用双区式电场结构，使静电场能均匀达到较大的平均电场强度，极大的增加了电场的净化面积，使电场与油烟粒子结合作用的时间更长，从而决定了雪聚油烟净化器具有极高的除油烟效率。

The electric field of the oil fume purifier uses the double area electric field structure, so that the electrostatic field can reach the larger average electric field strength, greatly increasing the area of the electric field and the time of combining the electric field with the oil smoke particles longer, thus determining the high efficiency of the removal of the fume in the snow fume purifier.

油烟净化器电场模块化设计，可按风量大小拼装成型，双区式的电场钢性好、便于拆装、不会变形，清洗、维护方便等特点。油烟净化器运行时噪音小，阻力小，运行成本很低。油烟净化器安全系数高，更好地高压连接设计，开门时电场会自动断电；另外，油烟净化器的电源是采用较新技术的直流迭加脉冲电源，双电流形式使油烟更容易被电离、吸附。电源在保证净化器好净化效果的同时，还具有自动的过载、过压、断路、开路保护，使用更安全、更放心。进出风口可随意互换，方便现场安装需要。油烟净化器净化效率高，经检测，能去除大部分气味。

The modular design of the electric field of the oil fume purifier can be assembled according to the size of the air. The electric field of the double zone type electric field is good, easy to be disassembled, not deformed, and convenient for cleaning and maintaining. Lampblack purifier operates with low noise, low resistance and low running cost. The safety factor of the fume purifier is high, the high voltage connection design is better, the electric field will be automatically cut off when the door opens; in addition, the power of the oil fume purifier is a DC superposition pulse power supply with the new technology, and the double current form makes the fume more easily ionized and adsorbed. The power supply ensures that the purifier has good purifying effect, but also has automatic overload, overvoltage, open circuit and open circuit protection. It is safer and more safe to use. The inlet and outlet can be exchanged at will, so as to facilitate on-site installation. The oil fume purifier has high purification efficiency and can remove most of the odors after testing.
