We offer filter bags for coking plants in a variety of sizes to meet the specific requirements of industrial production. Whether you require a standard size or a custom solution, our team of experts can work with you to design and manufacture the perfect filter bag for your application.
Description
Filter bags are used to treat smoke and harmful gases generated during the coking process, protect the environment and ensure the air quality of the factory. The coking process involves high temperatures and corrosive gases, which poses challenges to the material and performance of the filter bags.
Needle Felt Filter Bags
Needle felt filter bags have the advantages of high porosity, good air permeability, high filtration accuracy, and large dust holding capacity. They can effectively capture dust particles of various particle sizes and are high-quality materials for coking filtration treatment. By covering the surface of ordinary needle-punched felt filter material with a layer of polytetrafluoroethylene (PTFE) film, the film has the characteristics of smoothness, small and uniform pore size, which can significantly improve the filtration efficiency and achieve high-precision filtration.
Materials and Performance
| Filter Media | Temperature Range | Chemical Resistance | Filtration Precision | Durability | Application |
|---|---|---|---|---|---|
| PTFE needle felt | Up to 260°C (short-term), 230°C (long-term) | Excellent (Resistant to acids, alkalis, and solvents) | High (fine filtration for fine dust and fine particles) | Extremely durable, resistant to chemical corrosion | Gas Purification (Desulfurization, Deammoniation) |
| P84 needle felt | 260°C (short-term), 240°C (long-term) | Very good (resistant to acids and alkalis) | Medium (effective for high-temperature, high-dust applications) | Excellent resistance to high temperatures and abrasions | Gas Purification (Desulfurization, Deammoniation) |
| PPS needle felt | Up to 190°C (short-term), 180°C (long-term) | Good (resistant to acids and alkalis) | Medium to High (efficient in dust control in industrial processes) | Good durability, suitable for high-dust conditions | Coking Process (Coal Charging, Coke Pushing) |
| PTFE membrane needle felt series | 230°C (long-term) | Excellent (strong resistance to most chemicals) | Very high (provides enhanced filtration efficiency and dust release) | Long-lasting with excellent cake release and cleaning ability | Coking Process (Coal Charging, Coke Pushing) |
Performance Advantages
- High-efficiency dust removal
It can effectively remove dust from the exhaust gas of the coking plant, so that the exhaust gas meets environmental protection standards. The general filtration efficiency can reach more than 99%.
- High temperature resistance
Filter bags that can withstand different temperatures can be selected according to the production environment of the coking plant, such as the common filter bags that can withstand high temperatures of 200℃ – 260℃, which can meet the dust removal needs of high-temperature equipment such as coke ovens.
- Corrosion resistance
The exhaust gas of the coking plant contains acidic gases such as sulfur dioxide and nitrogen oxides. These filter bags can operate stably for a long time in harsh chemical environments.
- Long service life
The filter bags are reasonably designed and manufactured. Under normal conditions of use, they can be used for 1-3 years, reducing the workload and cost of frequent replacement of filter bags.
Structural Design
- Bag mouth
Usually adopts a metal reinforcement ring (such as stainless steel, galvanized steel) to facilitate the installation and fixation of the filter bag, and prevent the bag mouth from deformation during long-term use.
- Bag body
It is cylindrical, which is conducive to uniform gas distribution, reduces the scouring of airflow on the filter bag, and prolongs the service life of the filter bag. The length and diameter of the bag body are designed according to the specific dust removal equipment and working conditions.
- Bag bottom
Designed to be round or conical, so that dust can slide smoothly and avoid dust accumulation at the bottom of the bag causing blockage.
