What is the difference between plate type and bag type in primary efficiency filter?
The primary air filter is the primary filter for the air conditioning system, mainly used for filtering μ Dust particles above m. There are four types of primary effect filters: plate type, folding type, bag type and box type. The outer frame materials include paper frame, aluminum profile frame and galvanized plate frame. The filter materials include non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, aluminum rolled mesh, etc.
The advantages of the primary efficiency filter are low price, light weight, good versatility, compact structure, etc.
It is a special filter equipment with non-woven fabric, glass fiber, etc. as the filter material, wedge-shaped folding shape to increase the filtering area, metal wire mesh clamping or built-in metal dragon skeleton support, and metal frame to make a plate structure. It is characterized by small resistance, long service life, washability, economy and durability.
The primary filter structure is generally divided into dragon skeleton and frame skeleton. The keel frame is characterized by solid structure and uniform distribution of filter materials, but its production takes time and labor. The frame frame is characterized by convenient filter material replacement, time-saving production and slightly inferior strength than the dragon frame.
Plate type primary efficiency filter is generally used for prefiltration of central air conditioning and central ventilation system, prefiltration of large air compressor, clean return air system, and prefiltration of local high-efficiency filtering device.
It is a multi-purpose filtering equipment with novel structure, small volume, simple and flexible operation, energy saving, high efficiency, closed work and strong applicability. Bag filter is a new type of filtration system. The filter bag is supported by a metal mesh basket inside the bag filter. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. The impurities are trapped in the filter bag and can be used again after the filter bag is replaced.
The primary effect bag filter is made of synthetic fiber with gradually increasing density and strong toughness, and adopts seamless fusion technology, which has good air tightness and bonding strength, so as to avoid air leakage or cracking when the wind pressure is high, and the unique support design in the bag ensures its stable and optimal filtering effect; The filter material itself does not contain organic silicon, which is particularly suitable for use in paint spraying workshops.
The bag type primary filter is applicable to the front filter of the automobile painting workshop in the coating industry and the air conditioning application field, such as the air conditioning system in commercial buildings, warehouses, schools, laboratories and other places.
The product with large effective filtering area shall be selected for the primary efficiency filter, and the structure of the filter screen and the site service conditions shall also be considered. For example, bag filter screen can increase the filtering area by increasing the number of filter bags and the length of filter bags; For plate filter screen, the filtering area can be increased by increasing the thickness of plate filter screen or the discount quantity of filter element. Of course, it is also necessary to consider whether the site conditions allow, for example, whether the original length of the filter section of the air conditioning unit allows to increase the length of the bag, whether the installation frame of the plate filter screen allows to increase the thickness of the plate filter screen, and so on! Of course, for users, we still need to find more professional people to customize the design.
