What conditions will cause the dust filter bag to burn

The reason for the burning of the filter bag of the boiler bag filter is mainly caused by the high temperature of the exhaust gas. If the temperature of the exhaust gas treated by the dust collector exceeds the working conditions of the filter bag for a long time, it is easy to cause the filter bag to shrink hard, or melt to produce holes, and the sparks in the exhaust gas to flow in, or the dust to generate heat, may also cause the filter bag to burn into holes.

In addition to the high temperature burning of the bag, the sparks in the flue gas also seriously damage the bag of the dust collector. Such as coke ovens, drying kilns, chain furnaces, cupolas, electric furnaces, blast furnaces, mixed iron furnaces, etc., will have a lot of sparks entering the flue gas during the production process. When it is thin, it will cause sparks to burn through the filter bag and form irregular round holes. When the dust layer on the surface of the filter bag is thick, sparks will not directly burn through the filter bag, but form dark baking marks on the surface of the filter bag.

According to a comprehensive analysis, the reasons for the burning of the dust filter bag may be as follows:

1. High temperature: The high temperature generated by the dust collector will cause certain damage to the bag. If the temperature is too high, the bag may be burned.

2. Improper maintenance: For long-term use of cloth bags, if the regular cleaning and replacement are not properly maintained, it will lead to increased wear and tear and become easy to burn.

3. Excessive humidity: In a high-humidity environment, the cloth bag will absorb moisture and become soft, prone to building blocks or adhesions, resulting in different degrees of burning of different parts of the heat energy.

4. Static electricity: During the dust removal process, the bag may be charged with static electricity. After accumulating a certain amount of charge, encountering static sparks or arcs may cause the bag to burn.

Therefore, when using the dust collector, it is necessary to pay attention to regular maintenance to prevent damage to the bag from harsh environments such as high temperature and humidity, and to avoid the influence of adverse factors such as static electricity on the bag to prolong its service life.

The solution to the burning of the dust filter bag is also slightly different.

1. Static electricity problem:

Static electricity is one of the main reasons for the burning of dust bag. In order to solve the problem of static electricity, the following measures can be taken:

- Carry out grounding treatment of dust bag to reduce static electricity generation

- Install a static eliminator to eliminate static electricity in the air

- Choose a dust bag that meets the electrostatic protection standard

2. High temperature problem:

Another reason for the burning of the dust bag is high temperature. In a high temperature environment, the temperature resistance of the dust bag may be damaged, resulting in burning. In order to solve the high temperature problem, the following measures can be taken:

- Choose dust bag material suitable for high temperature environment

- Strengthen the cooling and heat dissipation capacity of the dust collector

- Regularly check the temperature of the dust collector to avoid excessive conditions

3. Humidity problem:

In a high-humidity environment, the dust bag is prone to mold, corrosion and other problems, which will also cause the dust bag to burn. To address humidity issues, the following measures can be taken:

- Regularly clean the inside of the dust collector and the dust bag

- Use moisture-proof, mildew-proof dust bag

- Reduce the time the dust collector is exposed to high humidity

The above are some measures to prevent the dust bag from burning. If the dust bag has burned, it needs to be replaced in time to solve the problem as soon as possible.
