High-Quality Steel Filter Bag Cage with Venturi for Industrial Dust Pump Systems

Structure and Principle

• Structural Composition: It is mainly made of high-quality steel, including longitudinal ribs and support rings. The longitudinal ribs are evenly distributed to provide strength and stiffness, and the support rings maintain the shape of the filter bag. It is also equipped with a Venturi tube, generally installed at the top of the filter bag, and cooperates with the blowpipe.

• Working Principle: The dusty gas enters the bag filter. The dust is intercepted on the outer surface of the filter bag, and the clean gas is discharged through the inside of the filter bag. During dust cleaning, the pulse valve opens, and compressed air is ejected from the blowpipe. Through the Venturi tube, the surrounding air is induced to enter the filter bag, making the filter bag expand sharply in an instant and shake off the dust.

Performance Advantages

• High Strength and Stability: High-quality steel ensures that the filter bag cage can withstand the gas pressure of the filter bag during the filtration and dust cleaning processes, preventing damage and deformation during transportation and installation, and ensuring long-term stable operation.
• Good Corrosion Resistance: Through treatments such as galvanizing, powder coating, and surface silicone spraying, it can resist the corrosion of dust in different industrial environments and extend its service life.
• Efficient Dust Cleaning: The Venturi tube can induce a large amount of surrounding air to enter the filter bag, enhancing the dust cleaning effect, reducing the frequency of dust cleaning, improving the efficiency of the dust collector, and reducing energy consumption.

Application Fields

• Metallurgical Industry: Such as steel plants and non-ferrous metal smelters. A large amount of dust is generated during the processes of ore crushing and smelting, and this equipment can be used for treatment.
• Chemical Industry: In chemical plants, various dusts and harmful particles are generated during the production process. This filter bag cage can effectively filter them to protect the environment and the health of workers.
• Building Materials Industry: In cement plants, stone material plants, etc., during the links of raw material grinding, cement production, and building material processing, this equipment can be used to control dust emissions
