How does the Venturi tube in the filter bag cage affect the performance of the dust pump system?

The Venturi tube in the filter bag cage affects the performance of the dust pump system in the following ways:

Improving Dust Removal Efficiency

  • Enhanced Dust Detachment: During the pulse – jet cleaning process, the Venturi tube causes the high – pressure air from the blowpipe to accelerate as it passes through the narrow throat section. This acceleration creates a negative pressure zone, which induces a large amount of surrounding air to be sucked into the filter bag. The combined effect of the high – pressure air and the induced air causes the filter bag to expand and contract rapidly, generating strong vibrations. These vibrations are highly effective in dislodging dust particles adhered to the filter bag surface, even those that are difficult to remove, thereby improving the overall dust removal efficiency of the system.

  • Thorough Cleaning of Filter Bags: The Venturi – induced air flow helps to ensure a more uniform cleaning of the filter bags. The air is distributed evenly throughout the filter bag, preventing uneven cleaning and reducing the likelihood of dust build – up in certain areas. This thorough cleaning helps to maintain the filtration performance of the filter bags over time, allowing them to continue to effectively capture dust particles and prevent dust from escaping into the atmosphere.

Reducing Energy Consumption

  • Efficient Use of Compressed Air: The Venturi tube enables the dust pump system to achieve a significant cleaning effect with a relatively small amount of high – pressure compressed air. By inducing a large volume of surrounding air, it supplements the cleaning air volume, reducing the reliance on a large – volume supply of high – pressure air. This efficient use of compressed air helps to lower the energy consumption of the air compressor that supplies the compressed air, resulting in energy savings for the entire dust pump system.
  • Optimized Cleaning Cycles: Due to the enhanced dust removal efficiency provided by the Venturi tube, the frequency of cleaning cycles can be reduced. The filter bags remain clean for longer periods, requiring less frequent activation of the pulse – jet cleaning system. This reduction in the number of cleaning cycles further contributes to energy savings, as each activation of the cleaning system consumes a certain amount of energy.

Protecting the Filter Bags and System Components

  • Reduced Mechanical Stress on Filter Bags: The gentle yet effective cleaning action of the Venturi – enhanced air flow helps to reduce the mechanical stress on the filter bags. The even distribution of air and the controlled expansion and contraction of the filter bags during cleaning minimize the occurrence of local stress concentrations, which can lead to premature wear and tear of the filter bags. By prolonging the service life of the filter bags, the Venturi tube helps to reduce the frequency of filter bag replacements, thereby reducing maintenance costs and downtime of the dust pump system.
  • Prevention of System Clogging: The efficient dust removal achieved by the Venturi tube helps to prevent dust from accumulating and clogging the filter bags, as well as other components of the dust pump system such as the ducts and the dust – collecting hopper. Clogging can lead to increased resistance to air flow, reduced system efficiency, and potential damage to the system. By maintaining a clean and unobstructed flow path, the Venturi tube helps to ensure the smooth operation of the dust pump system and protects its various components from damage caused by dust build – up.
