Filter bag use:
As the filter bag is the same as the filter network, it is also one of the components of the filter. The high temperature needling felt filter bag is undoubtedly the key part of the filter process. The reason is that the filter bag determines the filter effect of the user to a large extent. In general, the selection of filter bag is mostly the filter cloth produced by world famous enterprises, and the filter bag with patent structure ring mouth, it is better to use the filter bag made by professional production equipment. Some friends may think that there are so many materials and specifications in the bag. Sometimes you don't know how to make the choice. Next, we will have a comprehensive understanding of filter bags, and lay a good foundation for users to choose filter bags.
How much is the high temperature needled felt
First, let's look at the classification of filter bags:
The filter bag has a liquid filter bag:
The ring of filter bag can be divided into stainless steel ring, P ring and PE plastic ring, including a variety of bag bottom and bag top design.
There is also a liquid filter bag. The liquid filter bag has the following advantages:
1, even after the improvement of the bag mouth suture, there is still no high protrusion, resulting in the phenomenon of side leakage.
2, filter bag is produced by high-speed industrial sewing machine without silicone oil cooling. This production mode will not produce silicone oil pollution.
3, the filtration accuracy of filter bags ranges from 0.5 to 300 microns. The materials are divided into polyester and polypropylene nylon.
4. The labels of the product specifications and models on the filter bag are all selected to be easily replaced, in order to prevent the pollution caused by the filter bag in the use of the label and the ink on the filtrate.
5. Welding technology of stainless steel. The diameter of the filter bag is less than 0.5 mm, and the horizontal error is less than 0.2 mm. Installing it in the device can improve the sealing degree and reduce the probability of the occurrence of side leakage.
Liquid filter bags can be used to filter common industrial liquids, such as electroplating paint, ink, food, chemical and other chemicals. Acid resistance and high mechanical strength of fiber can also be used repeatedly.
However, the filter bag of air conditioning system is mainly used for filtration of air and dust particles in air supply system, so as to achieve the requirement of dust-free production environment.
Another kind of filter bag is called dusting filter bag, and the dusting bag refers to the matching bag in bag filter, which is made of filter cloth. This filter bag will produce a lot of dust in the process of thermal power generation, steel and cement industry, which will cause serious pollution to the atmosphere.
At present, no matter what type of filter bag, the air emission is strictly required. Filter bag is one of the ideal dedusting methods widely used in life. Besides the dust bag is called the heart of bag type dust collector, it plays a key role in the effect of dust removal. The quality of the filter bag also determines the quality of the dust bag. And the manufacturing technology and quality of bags is also one of the important factors that affect the filtration. It is not difficult to understand that poor filter bags cause trade leakage. So when choosing filter bags, we must choose according to our needs.
