Down flow type cartridge dust collector with high temperature, strong hydrophobic foldaway filter cylinder as the filter medium, it can filter dust containing gas in the wet state, the filter not only has the characteristics of small size, large filter area, and can be used for a long time at a certain temperature and temperature under the.
The filter cartridge is used for pulse cleaning of the filter cartridge in the form of constant resistance or timing, which ensures the surface cleaning and effective normal operation of the filter cartridge.
The filter is also equipped with a temperature display and alarm system, when the temperature exceeds the rated value, the automatic alarm, so that the corresponding measures to be taken in time.
Settling filter dust collector is a new generation product which can solve the high temperature, high humidity and coalescence dust. It is widely used in metallurgy, smelting and other industries and the treatment of high temperature dust containing gas.
Performance characteristics:
(1) the advanced settlement structure and the filter tube inclined loading structure are adopted, so that the dust collector has a good effect in the process of synchronization;
(2) the purification efficiency is high, for more than of the sub micron dust has more than 99.9% purification efficiency, equipment running resistance is low, effectively save the energy consumption of the dust removal system;
(3) the dust air inlet is provided with a dust retaining plate, which is provided with a buffer and a wear resistant function, so that the dust can not be directly impact on the filter cartridge, thereby prolonging the service life of the filter cartridge;
(4) the filter cylinder 15 is inclined to the drawer type installation, the filter cartridge can be removed for more convenient, and the dust collector does not set the transmission parts in the body, so that the maintenance work is reduced to a minimum. The general dust filter can be used for a long time without the need to replace the tedious work, eliminating the common bag type dust collector bag to wash frequently, and save a lot of maintenance costs;
(5) modular combination, the size can be arbitrarily selected, you can expand the original combination, increase the dust removal unit, and do not need to make too many changes to the original equipment.
Filter cartridge and filter material:
1 filter cartridge:
The filter element of the filter cartridge filter is a filter cartridge. The filter cartridge is divided into four parts, such as the top cover, the metal frame, the filter material and the base, and so on. The four part canister round, flat and tapered etc..
The cartridge is used to filter the length design of folded pleats are bonded into a tube, tube inside and outside the metal frame, and fixed with the top cover and the base. Top cover with fixed bolt and washer. The circular filter cartridge, the cartridge is flat.
The cartridge on the lower end cover, mesh adhesive should be reliable, should not degumming, adhesive leakage and sagging defect; metal cartridge should meet the requirements of anti rust; filtering cylinder should be no scars, bump, burr and burr; the cartridge blowing ash according to the need equipped with induction nozzle or venturi tube etc. The blowing device, the cartridge should be added inside the fence, when the D is larger than 320mm, H or 1200mm cartridge, should be equipped with induction nozzle.
Commonly used filter tube is divided into three categories. Table for different air filter to protect the object and the installation of parts.
The relationship between the volume of the filter tube and the volume of the filter is very large. Use the filter assembly machine, often to filter the following requirements: the dust collector and the import and export of high total distance (W); the total height and diameter of the filter cylinder body; the filter cylinder total quality; the outlet connection type and size; the performance requirements of filtration and the filtration performance of a series of related.
Filter design according to the requirements of the assembly should pay attention to the following elements:
(L) the outer diameter of the filter cartridge is larger than that of the inner diameter of the filter cartridge 10mm. This is because of the high and narrow space, can let pollution particles settling slowly in the cartridge so that the outer filter cylinder from top to bottom even accept the clogging.
(2) the determination of the diameter of the inner skeleton mainly considers the size of the oil through holes should not affect the filtration volume, and the effect of the small hole size on the strength of the frame.
(3) the total strength of the inner skeleton is very important. Firstly, the pressure difference should be taken into consideration to support the filter cylinder, so the smaller the diameter is, the higher the strength is.
(4) fold lines should be the best tooth height between l0~50mm.
(5) to fully leave the room for the calculation of the pressure difference of the filter and the product, the area should be increased by 1 times. This is because of the full consideration of the actual work, dust pollutants are unpredictable.
2 filter material:
Filter cartridge filter material has two kinds: one kind is the synthetic fiber filter material, one kind is the paper filter material.
Synthetic fiber nonwoven filter material. According to the machining process can be divided into continuous fiber spunbonded polyester staple fiber spinning polyester hot and sticky hot two. Waterproof material surface condition, filter water repellent treated the invasion angle should be greater than 90 degrees, water level is no less than grade. Filter oil treatment conditions, the filter material to do anti oil treatment. Polyester non-woven filter material can withstand the working temperature of not less than 120. For other special working conditions such as high temperature and high humidity, the material structure of the filter can be used to meet the requirements of application.
The filter paper can be divided into low permeability and high porosity of two.
In addition, synthetic fiber non-woven Teflon coated filter media and paper PTFE coated filter media
