1. Safety and quality requirements must be considered when designing circular or square cross-sectional area airbags.
2, air bag must have enough capacity to meet the amount of blowing gas. It is recommended that the pressure drop in the air bag after the pulse injection is not more than 30% of the original storage pressure.
3, air intake manifold diameter selection, meet the replenishment speed. Multiple intake air intake lines can be designed for large air bags.
4. For atmospheric airbags, 76mm diameter pipes can be used to connect multiple airbags into one air circuit.
5, the valve should be installed in the upper part of the air bag or side, to avoid the air bag of oil, water through the pulse valve into the filter bag. Submerged pulse valve should not be installed in the lower part of the air bag.
6. The bottom of each air bag must be equipped with an automatic (ie two-position two-way solenoid valve) or manual oil-water drain valve to periodically discharge the impurities in the container.
7, if the air bag is designed according to the pressure window standard, and there is enough large cellar basic body is a compressed gas regulator gas tank. When there is a stable tank before the air bag, it is necessary to install the tank close to the air bag to prevent the compressed air from losing pressure during the transfer process through the elongated pipe.
8. After the air bag is processed and produced, it must be continuously blown with compressed air to clean the ear and listen to the internal welding slag before installing the valve. When testing the pulse valve in the workshop, especially the 76mm diameter submerged valve, the pressure of the compressed gas and the flow of the supplement gas must be ensured, otherwise the pulse valve will not open or leak.
9. If the valve is installed on site, it is found that the upper outlet of the valve is leaking. That is because the air bag contains impurities that cause the rust on the small diaphragm to fail to close the valve. It is necessary to disassemble the small diaphragm to clean it.

Cement plant dust treatment or boiler flue gas purification according to the current environmental requirements are using pulse jet bag dust removal equipment, dust gas bag is a pulse dust collector gas storage device, the injected gas source is stored in the air bag. For the installation precautions for the dust-collecting air bag, Botou Chunhui Environmental Protection Equipment Co., Ltd. made the following explanation:
