The weight of the dust filter bag is ≥550g/m2 during the production process, and the thickness of the product is approximately 1.8~2mm. The fiber layer and the base cloth of the entire product are filtered in an external filter type, and the normal use temperature of the filter bag is in use. : ≤175°C; maximum instantaneous temperature: 200°C.
The basic requirements of dust filter bag
1. The material of the main body of the dust filter bag is PPS+PTFE. The weight of the ultrafine fiber is about 550g/m2.
2. The service life of the dust filter bag must be not less than 30,000 hours from the date of installation from the bag in accordance with its normal environmental conditions. If the filter bag is damaged at the specified time, the manufacturer shall be responsible for free replacement and shall not affect production or excessive emission of smoke. The
3. After the dust filter bag is used, it needs to effectively ensure that the smoke emission concentration is ≤25mg/m3.
Technical details of dust filter bag
1. Flue gas temperature: normal temperature of exhaust gas 120-160°C, filter life or differential pressure is not affected; exhaust temperature 190°C continuous operation does not exceed 5 minutes or cumulative operation does not exceed 30 minutes, filter life or differential pressure Not affected. The
2. Oxygen content of flue gas: The oxygen content of flue gas is less than 10%, and the filter life or differential pressure is not affected.
3. Flue gas flow rate: The filter bag flow rate during operation is 0.8-1.0m/min and the maximum is 1.1 m/min. The filter life or differential pressure is not affected. The
4. Flue gas humidity: The humidity of the flue gas does not exceed 8%. If the humidity of the flue gas exceeds 8%, the filter bag of the bag filter is prone to puckering, increasing the system resistance and affecting the service life of the filter bag.
