What is the pulse injection time for the pulse bag filter with an air box type

Pulse injection time refers to the time interval between the opening and closing of each pulse valve, and is an important parameter in the pulse injection cleaning process. The duration of pulse injection directly affects the dust removal effect and equipment energy consumption. If the pulse blowing time is too short, it will lead to incomplete dust removal and the dust on the surface of the cloth bag cannot be completely removed; If the pulse blowing time is too long, it will increase energy consumption and equipment wear. Therefore, selecting the appropriate pulse injection time is crucial for the normal operation of the gas box pulse bag filter.
Factors affecting pulse injection time
Dust properties: Different types of dust require different pulse injection times. For example, dust with larger particles and higher density requires a longer pulse blowing time to be removed. Therefore, selecting the appropriate pulse injection time based on the properties of dust is the key to improving dust removal efficiency.
Material and structure of cloth bags: Different materials and structures of cloth bags have different sensitivities to pulse blowing time. Generally speaking, high-density and fine aperture cloth bags require a shorter pulse blowing time, while low-density and coarse aperture cloth bags require a longer pulse blowing time.
Air source pressure and air volume: The air source pressure and air volume of the pulse valve can also affect the pulse injection time. When the gas source pressure is high and the gas volume is large, the pulse injection time can be shortened; When the gas source pressure is low and the gas volume is small, it is necessary to extend the pulse injection time.
Equipment model and specifications: Different models and specifications of air box pulse bag dust collectors have different structural characteristics and performance parameters. Therefore, it is necessary to choose the appropriate pulse blowing time based on the equipment model and specifications.
Operating conditions: The operating conditions of the equipment also affect the selection of pulse injection time. For example, when dealing with dusty gases with high temperature and humidity, it is necessary to extend the pulse blowing time appropriately to ensure the dust removal effect.
To choose the appropriate pulse injection time, it is recommended to consider the following aspects:
Referring to the recommended values provided by equipment manufacturers: Generally speaking, equipment manufacturers will provide recommended pulse injection time ranges based on the performance characteristics and actual application situations of the equipment. You can refer to these recommended values when making a selection.
Experiments and adjustments: For specific application scenarios and dust properties, experiments can be used to find the optimal pulse blowing time. Dust removal experiments can be conducted at different pulse injection times to observe the dust removal effect and energy consumption indicators, and adjust accordingly.
Consider the needs of equipment maintenance and repair: When selecting the pulse blowing time, it is also necessary to consider the needs of equipment maintenance and repair. If frequent replacement of filter bags or other maintenance operations are required, a shorter pulse blowing time can be selected for easy operation.
Maintaining stability and flexibility: To ensure the stability and adaptability of the equipment, an adjustable pulse injection time control system can be selected. This can be adjusted in real-time according to actual needs to meet different working conditions.
