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.

Can you provide more details about the Venturi tube in the filter bag cage?
Here are the detailed descriptions about the Venturi tube in the filter bag cage:
Structure
- The Venturi tube consists of a convergent section, a throat section, and a divergent section. The convergent section gradually narrows the flow channel of the gas, causing the gas velocity to increase and the pressure to decrease. The throat section is the narrowest part of the Venturi tube, where the gas reaches the maximum velocity and the minimum pressure. The divergent section then gradually expands the flow channel, allowing the gas velocity to decrease and the pressure to recover. In the filter bag cage, the Venturi tube is usually made of stainless steel or other corrosion – resistant materials to ensure its durability and reliability in harsh industrial environments.
Working Principle
- When the pulse – jet cleaning system is activated, high – pressure air is injected into the filter bag through the blowpipe. As the air passes through the Venturi tube, the constricted throat section causes the air to accelerate. According to the principle of conservation of energy, the increase in air velocity leads to a decrease in static pressure, creating a negative pressure zone. This negative pressure zone induces a large amount of surrounding air to be sucked into the filter bag. The combined effect of the high – pressure air from the blowpipe and the induced air causes a rapid expansion and contraction of the filter bag, generating a strong vibration that effectively detaches the dust adhered to the filter bag surface.
Functions
- Enhanced Dust Removal Efficiency: By inducing a large volume of additional air, the Venturi tube significantly increases the air volume and momentum entering the filter bag during the cleaning process. This powerful air flow can more effectively dislodge the dust particles, especially those that are firmly attached to the filter bag, thereby improving the dust removal efficiency and ensuring the cleanliness of the filter bag.
- Reduced Energy Consumption: The Venturi tube enables the use of a relatively small amount of high – pressure air to achieve a large – scale cleaning effect. It utilizes the energy – saving principle of inducing surrounding air, reducing the need for a large amount of high – pressure air supply. This helps to lower the energy consumption of the dust removal system, resulting in significant energy savings and reduced operating costs.
- Uniform Cleaning: The design of the Venturi tube ensures a relatively uniform distribution of the air flow entering the filter bag. This uniformity helps to avoid local over – cleaning or under – cleaning, ensuring that the entire filter bag is cleaned evenly. As a result, the service life of the filter bag is prolonged, and the filtration performance of the dust collector is maintained at a stable level.

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

What is a water filter bag?
A water filter bag is a filtration device mainly used to remove impurities, suspended solids and other substances in water to purify water quality. The following is a detailed introduction:
Structure and Material
- Structure: Generally, a water filter bag is a bag-shaped structure with an opening at one end. The opening is usually designed with a ring or other fixing device for easy installation and connection to the water filtration system.
- Materials: It is often made of various filter materials such as polyester, polypropylene and nylon. These materials have different filtration precisions and chemical resistances to meet different filtration requirements. For example, polyester filter bags have good strength and chemical stability, while polypropylene filter bags are known for their excellent acid and alkali resistance.
Working Principle
- The water to be filtered enters the filter bag through the inlet. As the water passes through the filter material of the bag, impurities, suspended solids, and particulate matter in the water are trapped by the filter material due to the sieving and adsorption effects. The filtered water then passes through the filter bag and flows out through the outlet, thus achieving the purpose of water purification. The filtration precision of the filter bag can range from a few microns to hundreds of microns, depending on the specific application and the fineness of the filter material.
Applications
- Industrial Fields: In industrial water treatment, such as in the chemical, electroplating, and pharmaceutical industries, water filter bags are used to remove impurities in process water to ensure the quality of products and the normal operation of production equipment. They can also be used in industrial wastewater treatment to reduce the content of pollutants in the wastewater before it is discharged.
- Domestic Use: In household water purification systems, water filter bags are often used as the first stage of filtration to remove large particles of impurities, rust, and sediment in tap water, prolonging the service life of subsequent water purification equipment such as water purifiers and improving the quality of domestic water.
- Aquaculture: In aquaculture, water filter bags are used to filter pond water or circulating water in aquaculture systems to remove uneaten feed, fish feces and other impurities, maintaining good water quality and a suitable living environment for aquatic organisms.
- Swimming Pools: In swimming pool water treatment systems, water filter bags play a role in filtering out suspended matter, leaves and other impurities in the water to keep the pool water clean and clear and reduce the burden of disinfection and purification equipment.
