The volume of filter cartridge is very much related to the volume of filter assembly. Using the mainframe of the filter assembly, the following requirements are often made to the filter: (1) the total height of the dust collector and the distance of the import and export (wide); (2) the total height and diameter of the lower body of the filter; (3) the total mass of the filter tube; (4) the connection mode and size of the outlet and the size of the outlet, and the performance requirements of the filtration characteristics. Filter cartridge design should pay attention to the following elements according to assembly requirements.
(1) the outer diameter of the cartridge is larger than 10mm of the inner diameter of the cartridge. This is due to the high and narrow space, which allows the settling of contaminating particles in the outer layer of the filter cartridge, so that the filter cartridge is evenly polluted from top to bottom.
(2) the determination of the diameter of the inner framework is mainly due to the size of the oil hole, which should not affect the filtration volume, while taking care of the influence of the size of the hole on the strength of the skeleton.
(3) the overall strength of the inner framework is very important. First of all, the pressure difference of the filter cartridge should be considered to be supported by the skeleton, so the smaller the diameter is, the higher the strength is.
(4) the height of the wrinkle teeth should be selected between l0~50mm.
(5) the limit of pressure difference should be kept sufficiently. When the required filter is accumulated, the area should be increased by 1 times. This is because the dust pollution is unpredictable in the actual work.
There are two kinds of filter media for filter cartridge: one is synthetic fiber filter material, the other is paper filter material.
Synthetic fiber nonwoven filter. According to the processing technology, it can be divided into two types: continuous fiber spunbond polyester hot pressing, short fiber spinning, sticky polyester hot pressing. When the surface of the filter material is waterproofing, the wetting angle of the filter material after waterproofing should be greater than 90 degrees, and the water level should be no less than grade IV. When the filter material is oil resistant, the filter material is protected from oil. Polyester nonwoven filter material can withstand working temperature of not less than 120 C. For other special working conditions such as high temperature and high humidity, the selection of material structure of filter cartridge should meet the application requirements.
Paper filter media can be divided into two categories: low permeability and high permeability.
In addition, there are synthetic fiber nonwoven PTFE coated filter material and paper PTFE membrane filter material.
