For the filter bag, as the name suggests, like the filter, it is also one of the components of the filter. The filter bag is undoubtedly a key part of the filtration process. The reason for this is that the filter bag largely determines the user’s filtration. effect. In general, the selection of filter bags is mostly the filter cloths produced by world-famous companies, and it is equipped with a filter bag with a patented structural ring mouth, and the filter bags can be manufactured using professional production equipment. Some friends may think that the filter bag material so much, and so complete specifications. Sometimes I don’t know how to make the choice. Next we will make a comprehensive understanding of the filter bag, in order to lay a good foundation for users to choose filter bags.
First of all, let’s look at the classification of filter bags:
Filter bag with liquid filter bag:
The filter bag ring mouth can be divided into stainless steel ring mouth, P ring mouth, PE plastic ring mouth, including a variety of different 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 bag mouth suture is improved, there is still no high protrusion, resulting in side leakage.
2. The filter bag is produced by high-speed industrial sewing machine without silicone oil cooling. This production mode will not cause the problem of silicone oil pollution.
3, filter bag filtration accuracy range from 0.5 to 300 microns. Its material is divided into polyester and polypropylene nylon.
4. The label of the product label of the filter bag on the filter bag is all easy to replace. The purpose is to prevent the contamination of the filter caused by the label and the ink in the use of the filter bag.
5, stainless steel welding technology. So that the filter bag diameter error is less than 0.5 mm, the horizontal error is less than 0.2 mm. Mounting it in the device can increase the degree of sealing while reducing the probability of occurrence of side leakage.
Liquid filter bag products can be used to filter general industrial liquids, such as electroplating paint, ink, food, chemical and other chemical liquids. Acid resistance and fiber mechanical strength can also be used repeatedly.
However, the air conditioning system filter bag is mainly used to filter the air dust particles in the air supply system to achieve dust-free production environment requirements.
There is also a filter bag called a dust filter bag, which refers to a cloth bag in a bag filter and is a filter bag made of a dust cloth. Such filter bags generate a large amount of dust during the production process of thermal power generation, steel, and cement industries, thereby causing serious pollution to the atmosphere.
At present, no matter what kind of filter bags are used, strict requirements are imposed on atmospheric emissions. In daily life, filter bags are one of the ideal dust removal methods widely used, except that dust bags are called the heart of bag filters. It plays a key role in dust removal. The quality of the filter bag also determines the quality of the bag. The production process and quality of the bag are also one of the factors that affect the filtration. It is not difficult to understand that poor filter bags do unions and lead to powder leakage. Therefore, when choosing a filter bag, it must be properly selected according to your needs.
