    • 产品信息
    • 名称： AOBO-无隔板高效空气过滤器 
    • 品牌： AOBO 
    • 货号： AOBO-16 
    • 产品特点
    • 当减少过滤器的尺寸和重量时还可以提升它的风量。 对于很小的空间对风速的需求可以生产更大风量的产品。 为了便于搬运、安装，可以提供较小，较轻的外框以降低重量。 很好的产品设计可以灵活地对产品进行安装、更换及升级。 产品性能好于 2 倍外框高度的有隔板过滤器。 55mm , 70mm 及 75mm 褶高的产品可以降低产品阻力，提高过滤效率，性能好于市场上其它的无隔板产品。 当使用 55mm 70mm , 75mm 褶高的产品是可以减低产品阻力为系统带来节能效益。

 When reducing the size and weight of the filter can also improve its volume. Demand for small space for wind speed can produce greater air volume of the product. For ease of handling, installation, can provide smaller, lighter frame in order to reduce weight. Good products can be designed flexibly for installation, replacement and upgrading products. Product performance is better than 2 times the casing outside the height of the baffle plate filter. 55 mm, 70 mm and 75 mm high fold product can reduce resistance, improve the efficiency of filtering, the performance is better than other tinder barrier-free products on the market. Fold when using 55 mm to 70 mm, 70 mm high product resistance can be reduced for the system energy saving benefit.

拦截
空气中的尘埃粒子，随气流作惯性运动或无规则布朗运动或受某种场力的作用而移动，当微粒运动撞到其它物体，物体间存在的范德华力（是分子与分子、分子团与分子团之间的力）使微粒粘到纤维表面。进入过滤介质的尘埃有较多撞击介质的机会，撞上介质就会被粘住。较小的粉尘相互碰撞会相互粘结形成较大颗粒而沉降，空气中粉尘的颗粒浓度相对稳定。室内及墙壁的退色就因为这原因。
把纤维过滤器像筛子一样看待是错误的。
 
惯性和扩散
颗粒粉尘在气流中作惯性运动，当遇到排列杂乱的纤维时，气流改变方向，粒因惯性偏离方向，撞到纤维上而被粘结。粒子越大越容易撞击，效果越好。
小颗粒粉尘作无规则的布朗运动。颗粒越小，无规则运动越剧烈，撞击障碍物的机会越多，过滤效果也会越好。空气中小于0.1微米的颗粒主要作布朗运动，粒子小，过滤效果好。大于0.3微米的粒子主要作惯性运动,粒子越大效率越高。扩散和惯性都不明显得粒子最难过滤掉。测量高效过滤器性能时，人们经常规定测量最难测量的粉尘效率值。
 
静电作用
由于某种原因，纤维和微粒可能带上电荷，产生静电效应。带静电的过滤材料过滤效果可以明显改善。原因：静电使粉尘改变运动轨迹并撞上障碍物，静电使粉尘在介质上粘的更牢。
能长期带静电的材料也称作"驻极体"材料。材料带静电后阻力不变，过滤效果会明显改善。静电在过滤效果中不起决定作用，只起辅助作用。
 
化学过滤
化学过滤器主要有选择性的吸附有害气体分子。
活性碳材料中有大量看不见的微孔，有较大的吸附面积。米粒大小的活性碳中，微孔内面积有十几平方米大。
游离分子接触活性碳后，在微孔中凝聚成液体因毛细管原理呆在微孔中，有的与材料和而为一体。没有明显化学反应的吸附称为物理吸附。
有的对活性碳进行处理，被吸附的颗粒与材料进行反应，生成固体物质或无害气体，称为化学吸附。
活性碳在使用过程中材料的吸附能力不断减弱，当减弱到某一程度，过滤器将报废。如果仅为物理吸附，用加热或水蒸汽熏可使有害气体脱离活性碳，使活性碳再生。
 
重力效应
微粒通过纤维层时，在重力作用下，发生脱离气流流线的位移而沉降在纤维表面上，这种作用只有在微粒较大（>0.5um)时存在，这是微粒重力作用太小，当它还没有沉降到纤维上时已随气流通过纤维层。因而，对粒径小于0.5um的微粒的过滤，重力沉降完全可以忽略。

 

intercept

Dust particles in the air, with the air flow for inertial motion or random Brownian motion or movement by the role of a certain field force, when particles hit other objects, the object of van der Waals force between (is molecules and molecular, molecular mass and the force between the molecular mass) make particles adhering to the fiber surface. Enter the filter medium of dust have more chance to hit medium, hit medium will be stuck. Smaller dust will collide with each other mutual bond formation of larger particles and subsidence, concentration of dust particles in the air is relatively stable. Interior walls and the fading of for this reason.

The fiber filter like a sieve view is wrong.

Inertia and diffusion

Particles of dust in the air for inertial movement, when encounter arranged disorderly and fibre, air change direction, because of inertia swerve, and bumped on fibre by adhesive. The particle is larger, the easier the impact, the better the results.

Small particles of dust for random Brownian motion. The more severe the smaller particles, has no regulation motion, chance to hit an obstacle, the more the better filtering effect will be. In the air is less than 0.1 microns particles mainly for Brownian motion, small particles, filtering effect is good. Greater than 0.3 micron particles mainly inertia motion, the bigger the particle efficiency is higher. Diffusion and inertia are unknown is one of the most difficult to filter out particles. When measuring high efficiency filter performance, people often prescribed most difficult measurement of dust efficiency value.

Electrostatic interaction

For some reason, fiber and particle could take charge, produce electrostatic effect. With electrostatic filter material filtering effect can be improved significantly. Reason: electrostatic dust changing trajectory and hitting obstacles, electrostatic dust sticky stronger on the medium.

Long-term with electrostatic material is also called "electret materials. Materials with electrostatic resistance is changeless, after filtering effect will be improved significantly. Electrostatic not decisive role in the filtering effect, only a supplementary role.

Chemical filter

Chemical filter main selective adsorption harmful gas molecules.

Abound in invisible microporous activated carbon materials, have larger adsorption area. The size of a grain of activated carbon, the micro hole area of about a dozen square meters big.

After free molecules, activated carbon, condensed into a liquid by capillary principle in microporous stay in micro hole, some with material and as a whole. There is no obvious chemical reaction is called physical adsorption.

Some process, activated carbon adsorption of particles and the material for reaction, generate solid matter or harmless gas, known as chemical adsorption.

Activated carbon materials in the process of using the adsorption ability of weakening, when reduced to a certain extent, the filter will be scrapped. If only for physical adsorption, heat or steam smoked can make the harmful gas from activated carbon, activated carbon regeneration.

Gravity effect

Particles through fiber layer, under the action of gravity, from the displacement of air flow and sedimentation on the fiber surface, the effect only when large particles (> 0.5 um) exist, this is too small particles gravity, when it hasn't settlement on the fiber has been with the air flow through the fiber layer. Therefore, the grain size is less than 0.5 um particle filtering, gravity sedimentation can be ignored completely.
