Fiberglass bag filters and chemical fiber bag filters
In industrial production, gas filtration is a very important link, and the bag filter is one of the most commonly used equipment. According to the different filter media, the bag filter can be divided into two types: glass fiber bag filter and chemical fiber bag filter. These two filters are different in terms of filtration performance, scope of application, and use environment, etc., and the two filters will be compared in detail below.
1. Filtration performance.
The glass fiber bag filter uses glass fiber as the main filter material, which has high heat resistance and chemical stability, and is suitable for filtering liquids in harsh environments such as high temperature, acidity, and alkaline. Its filtration accuracy can reach the level, which can effectively remove impurities such as tiny particles, suspended solids, colloids and other impurities in the liquid. In addition, the pore size of the glass fiber filter cloth is evenly distributed, which enables efficient filtration, and is not easy to clog, easy to clean and replace.
The chemical fiber bag filter uses chemical fiber filter cloth as the main filter material, which has good temperature resistance and wear resistance, and is suitable for filtering liquids at general temperature. Its filtration accuracy can generally reach the mesh level, which can remove impurities such as larger particles and suspended solids in the liquid. The pore size of the chemical fiber filter cloth is relatively large, which is easy to cause turbidity and clogging of the filtrate, and needs to be cleaned and replaced frequently.
2. Scope of application.
The glass fiber bag filter is suitable for the filtration of corrosive liquids such as acids, alkalis, and salts, as well as the filtration of high-temperature, high-pressure, and high-viscosity liquids. It is widely used in electronics, chemical, pharmaceutical, food and other industries. In addition, due to the special properties of the glass fiber filter cloth, the glass fiber bag filter is also suitable for occasions with high requirements for filtration accuracy.
The chemical fiber bag filter is suitable for the filtration of general liquids, such as water, oil, alcohol, etc. It is widely used in machinery, construction, electric power, textile and other industries. Due to the relatively low ** of the chemical fiber filter cloth, the chemical fiber bag filter is also suitable for occasions with low filtration requirements.
3. Use environment.
Fiberglass bag filters are suitable for various harsh environments, such as high temperature, high pressure, corrosion, etc. In the process of use, it is necessary to select the appropriate model and filter media according to the specific environment to ensure its normal operation and prolong the service life. At the same time, because the fiberglass filter cloth is fragile, it needs to be handled carefully to avoid violent vibration and collision.
The chemical fiber bag filter is suitable for liquid filtration in general environments. During use, care needs to be taken to avoid exposing the filter cloth to the air for a long time to avoid moisture and pollution. At the same time, it is also necessary to avoid mixing impurities such as hard objects in the chemical fiber bag filter, so as not to damage the filter cloth and affect the filtration effect.
To sum up, glass fiber bag filter and chemical fiber bag filter have their own advantages and disadvantages and scope of use. When choosing, it is necessary to consider comprehensively according to the specific needs and use environment. If high-efficiency filtration is required and suitable for harsh environments such as high temperature and corrosion, glass fiber bag filter is a better choice; If you only need general filtration and have a limited budget, a synthetic bag filter is a more cost-effective option. When in use, it needs to be operated and maintained correctly according to the product instructions to ensure its normal operation and prolong its service life.
