Venturi

The venturi made by die-casting aluminum alloy, used for point-jet pulse jet bag filters to guide jetting of the blown gas source to improve the dust. A Venturi in the context of filter bag cages (commonly used in dust collection systems) refers to a specially designed nozzle that enhances the cleaning efficiency of pulse-jet bag house filters. It works by accelerating compressed air through a constricted throat, creating a low-pressure zone that induces secondary airflow, thereby improving dust dislodgement from filter bags.

1. Enhanced Pulse-Jet Cleaning

2. Structural integration with filter cages

3. Material & durability considerations

Leveraging its core advantage of utilizing fluid kinetic energy to achieve negative-pressure suction, mixing, or metering, Venturi tubes are primarily applied in five major industries: petrochemicals (oil-gas transportation and mixing), water treatment (sewage aeration and chemical dosing), energy and power (boiler flue gas desulfurization and denitrification), metallurgical industry (dust collection in metal smelting), and aerospace (fluid control in propulsion systems). They are suitable for meeting the needs of fluid transportation, gas-liquid mixing, and precision metering in various scenarios.

• Focused on core filter material R&D, it relies on high-precision forming processes and selection of temperature-resistant & corrosion-resistant base materials. Through refined control, it ensures uniform filter pore size and stable filtration efficiency, laying a high-performance foundation for the entire series of filter bag products.

• Supported by automated modular assembly, combined with vision-guided precision assembly and full-process sealing & pressure resistance testing, it ensures finished filter bags are leak-proof and breakage-resistant, adapting to harsh dust removal conditions across multiple industries.
• Specializing in multi-material precision manufacturing, covering galvanized steel, spring steel, stainless steel and other materials, it strictly controls dimensional accuracy through CNC machining, ensuring stable cage structure and uniform supporting force, providing reliable guarantee for high-frequency pulse cleaning.
