What are the precautions for the installation of PPS filter bag?
PPS filter bag is a kind of high temperature flue gas filter material, which is commonly used in the field of flue gas purification. When installing PPS filter bag, the following matters shall be noted:
1. size of filter bag: when installing PPS filter bag, first confirm whether the size of filter bag matches the filtering equipment. The length, diameter and diameter of the filter bag shall correspond to the filter notch of the equipment.
2. number of filter bags: determine the number of filter bags to be installed according to the flue gas flow and purification requirements. Too few filter bags may not meet the purification requirements, and too many will increase the pressure loss.
3. filter bag material: PPS filter bag is a kind of polyamide fiber material with good high temperature resistance, but it cannot contact with strong acid, alkali and other substances, otherwise it may cause damage to the filter bag, so it is necessary to check whether the filter bag is intact before installation.
4. sealing of filter bag interface: when installing the filter bag, ensure the sealing of the interface between the filter bag and the equipment. If it is not tight, air leakage may occur, affecting the purification effect.
5. filter bag connection mode: select the appropriate filter bag connection mode according to the actual situation. Common connection methods include steel ring connection, galvanized steel sheet connection, etc. During installation, pay attention to the fixation of the connection to avoid loosening or slipping of the filter bag.

6. installation sequence of filter bags: determine the installation sequence of filter bags according to the equipment structure and filter bag layout. Generally, filter bags are installed layer by layer from top to bottom to ensure continuity and uniformity of flue gas filtration.
7. filter bag adjustment and alignment: after installing the filter bag, it is necessary to adjust and align the filter bag to ensure that the filter bag is flat and uniform. When adjusting the filter bag, avoid using excessive force to avoid damaging the filter bag.
8. filter bag cleaning: before installing the filter bag, clean the filter bag to remove dust and debris. During cleaning, avoid using hard or sharp tools to avoid scratching the surface of the filter bag.
9. filter bag replacement cycle: determine the replacement cycle of the filter bag according to the service life and purification effect of the filter bag. During use, the condition of the filter bag shall be checked regularly. If the filter bag is found to be seriously worn or damaged, it shall be replaced in time.
10. safe operation: when installing the filter bag, pay attention to safe operation and wear protective equipment to prevent accidental injury. At the same time, relevant operating procedures and safety standards shall be followed.
In short, the installation of PPS filter bags needs to consider the size, quantity, material and other factors of the filter bags to ensure the reliability of the interface seal and connection mode between the filter bags and the equipment. The filter bag shall be cleaned and adjusted before installation. After installation, the filter bag shall be regularly inspected and replaced, and attention shall be paid to safe operation. These precautions can ensure the effective operation and long-term use of PPS filter bag.
