Two aspects of the problem for everyone to introduce, one is the air purifier; the second air purifier principle.
What is an air purifier?
Air purifiers, also known as "air cleaners", air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, activated carbon, Synthetic fiber, HEAP high efficiency material, negative ion generator, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used.
Two air purifier principle
The air purifier is mainly composed of a motor, a fan, an air filter and the like. The working principle is as follows: the motor and the fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, some models of air purifiers will also be equipped with a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage when working), the air is continuously ionized, a large amount of negative ions are generated, and is sent by the micro fan. Form a negative ion airflow to achieve the purpose of cleaning and purifying the air.
Passive adsorption filter purification principle (filter purification)
The main principle of the passive air purifier is to use a fan to pump air into the machine and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gas and kill some bacteria. The filter screen is mainly divided into: a particulate filter and an organic filter. Particulate filter
Also divided into coarse filter, and fine particle filter
The quality of the fan and filter of this type of product determines the effect of air purification. The location of the machine and the layout of the room also affect the purification effect.
Active purification principle (no filter type)
The fundamental difference between the principle of active air purifier and the principle of passive air purging is that the active air purifier is free from the limitations of the fan and the filter screen, and is not passively waiting for the indoor air to be pumped into the purifier for filtration and purification. It is an effective and active release of the purification and sterilization factor into the air. Through the characteristics that the air will diffuse, it will reach the corners of the room and clean the air without dead angle.
The technologies for purifying sterilization factors in the market mainly include silver ion technology, negative ion technology, low temperature plasma technology, photocatalytic technology and plasma ion group ion technology. The biggest drawback of this type of product is the problem of excessive ozone emission.
Double purification class (active purification + passive purification)
This purifier is actually a combination of passive purification technology and active purification technology.
Plastic Frame Shaker Screen
Plastic Frame Shaker Screen is made by polyurethane material frame with two or three layers 304 or 316 Stainless steel wire cloth, Main feature as follows.
1.High strength plastic frame and moderate tension screen cloth that from a reliable whole, greatly enhance the tolerable.
2.The screen is divided into several independent small cloths to pervent excessive expansion of local damage.At the same time, With a special rubber plug to repair damage, it can save time and reduce use-cost.
3.Rapid wedge tensioning devices make screen installation more convenient, and save the time of machine half for changing.
4.Excellent polyurethane material frame enhance corrosion resistance, have a good stock absorption and ectend working life of screen.
MI-Swaco Shaker Screen
MI-Swaco is a world leading Oil and Gas service company. The shale shakers provided are widely used in oil gas drilling applications. H Screening studied MI Swaco shakers and manufactures high quality screen replacement for the following shaker Series:
Mongoose Shale Shaker Screen comes with either steel frame or composite material frame screen. H Screening produces both type of screens. We highly recommend the composite material frame screen which enjoys a longer service and reduces the downtime during operation.
