I. Introduction
The dust bag is the core component in the dust collector and is used to capture and filter dust particles in the air. Laminated dust bags and ordinary dust bags are two common types of dust bags, and there are certain differences in their materials, properties and use environment. This article will introduce in detail the difference between film-coated dust bags and ordinary dust bags, to help customers better understand and choose suitable dust bags.
Second, the characteristics of the film dust removal bag
Material: Laminated dust bags are generally made of high-performance materials such as polytetrafluoroethylene (PTFE), while ordinary dust bags are usually made of polyester felt, polypropylene felt and other materials.
Filtration performance: The coated dust bag has extremely high filtration accuracy and efficiency, which can effectively capture and filter fine dust particles, such as PM25 etc. The filtration accuracy and efficiency of ordinary dust removal bags are relatively low, and they are suitable for filtering larger dust particles.
Temperature resistance: The laminated dust removal bag has good temperature resistance, can operate at a higher temperature, and is suitable for the treatment of high-temperature flue gas. The temperature resistance of ordinary dust removal cloth bags is relatively poor, and it is suitable for normal temperature or low temperature environment.
Resistance: Because the film dust removal bag is made of high-performance materials, its resistance is large and the energy consumption is relatively high. The resistance of ordinary dust removal bags is less and the energy consumption is lower.
Service life: The service life of the laminated dust bag is long, generally up to several years or even longer. Ordinary dust bags have a relatively short service life and need to be replaced regularly according to the usage.
3. The characteristics of ordinary dust removal bags
Material: Ordinary dust bags are usually made of polyester felt, polypropylene felt and other materials.
Filtration performance: The filtration accuracy and efficiency of ordinary dust bags are relatively low, and they are suitable for filtering larger dust particles, such as PM10, etc. The filtration effect of fine dust particles is not as good as that of the coated dust bag.
Temperature resistance: The temperature resistance of ordinary dust removal bags is relatively poor, and it is suitable for normal temperature or lower temperature environment. Operating in a high-temperature environment may affect its performance and service life.
Resistance: The resistance of ordinary dust removal bags is small, and the energy consumption is low. Compared with the laminated dust bag, it has superior economy.
Service life: The service life of ordinary dust bags is relatively short, and they need to be replaced regularly according to the use case. This increases operating costs and maintenance effort.
Fourth, the selection of application scenarios
High-performance dust handling: For scenarios that need to deal with high-performance dust, such as semiconductor, electronics and other industries, coated dust bags have better filtration performance and temperature resistance, which is an ideal choice.
Normal or lower temperature environment: For dust treatment in normal or low temperature environment, such as steel, coal and other industries, ordinary dust removal bags have superior economy and can meet basic filtration needs.
Special environment: For some special environments, such as flammable and explosive, chemical corrosion, etc., the laminated dust bag has good flame retardancy and chemical stability, which is a safer choice.
V. Conclusions
To sum up, there are certain differences between the coated dust bag and the ordinary dust bag in terms of material, performance and use environment. When customers choose dust bags, they need to consider comprehensively according to the actual needs and working conditions. For high-performance dust handling, high-temperature environments or special occasions, laminated dust bags are a more suitable choice;In the case of normal temperature or lower temperature environment and high economic requirements, ordinary dust removal bags can meet the basic needs. Choosing the right bag can improve air quality, employee health, and environmental safety, while reducing operating costs and maintenance effort.
