Bag filter is a device used to effectively clean the emissions generated during the production process of asphalt mixture. It is usually in bulk and consists of a base, shell, inlet and outlet chambers, bag, and pulse combination.

 

1. Characteristics of bag filter. The domestic transportation production industry often uses dust collectors, not only because of their independent production and extended service life, but also because of their other advantages. Specific advantages include high dust removal efficiency, especially for the treatment of submicron dust, which is very good. As its processing object requirements are not very high, the smoke content and dust content have little impact on the dust collector, so bag filters can be widely used. In addition, the maintenance and repair of bag filters are simple and easy to operate.

 

2. The working principle of bag filter. The working principle of a bag filter is simple. It usually uses its own bag to effectively treat the dust in the flue gas. This treatment method has mechanical controllability, so while intercepting the dust, clean air will be discharged. The intercepted dust will be collected in a funnel and then discharged through the system's pipeline. The operation of bag filter is simple and easy to disassemble and maintain, so it is widely used in the treatment of emissions.

 

 

3. The influencing factors of bag filter. The service life of bag filter is limited, and in order to extend the service life of the dust collector, it is necessary to promptly troubleshoot. There are two factors that often affect the normal use of bag filters, namely the frequency of dust cleaning and bag management. The frequency of dust removal can affect the service life of the bag filter. If the frequency is too high, it can cause damage to the bag of the dust collector. Usually, a layer of filter bed is applied to the filter bag of the dust collector to extend its service life.

 

Insufficient daily care of cloth bags can also affect the service life of cloth bag dust collectors. Therefore, certain preventive measures should be taken, such as preventing the cloth bags from getting damp, from being exposed to direct sunlight, and from deteriorating. In addition, during the operation of the bag, the temperature of the exhaust should reach the normal standard.
