The filter bag of the dust collector in the asphalt mixing plant is a very important equipment, which can effectively purify the exhaust gas generated by the asphalt mixing plant, protect the environment and the health of workers. This article will provide a detailed introduction to the functions of filter bags, types and selection of filter bags, maintenance and replacement of filter bags, and other aspects.
1、 The function of filter bags
The exhaust gas generated by the asphalt mixing plant contains a large amount of dust and particulate matter. If not effectively treated, it will cause serious pollution to the environment. As the core component of the dust collector, the filter bag can filter out dust and particulate matter in the exhaust gas, making the exhaust gas emissions meet national standards, protecting the environment and the health of workers.
2、 Types and selection of filter bags
According to different working environments and processing requirements, filter bags can be divided into various materials and types. Common filter bag materials include polyester fiber, glass fiber, polypropylene fiber, etc., while the types of filter bags include bag filter bags, cylindrical filter bags, etc. When selecting a filter bag, it is necessary to consider factors such as temperature, humidity, and dust concentration in the working environment, as well as indicators such as wear resistance, high temperature resistance, and filtration efficiency of the filter bag.
3、 Maintenance and replacement of filter bags
In order to ensure the normal operation and service life of the filter bag, regular maintenance and replacement are required. Maintenance work includes regularly cleaning the dust accumulation on the surface of the filter bag, checking the damage of the filter bag, adjusting the tension of the filter bag, etc. Replacing the filter bag requires judgment based on its service life and filtration effect. Generally, the service life of the filter bag is 1-2 years, but adjustments need to be made according to specific circumstances.
