Industrial filter bag cage air dust collector

Types of Industrial Filter Bag Cages

An industrial filter bag cage is a framework designed to hold dust collector filter bags. It offers structure and support to the bag to enhance filtration performance and simplify maintenance. Choosing the right bag cage is just as important as selecting an appropriate filter. Bag cages come in various shapes, sizes, and types to meet diverse dust collection needs.

• Single Bag Cage

  A single bag filter cage is designed to hold only one filter bag. It is widely used in dust collectors and separators with compact systems or limited space. Single bag filter cages provide effective filtration for low to moderate dust loads. In addition, they simplify maintenance due to their smaller size. One potential drawback is that single bag cages may have a lower filtration capacity compared to models that hold multiple bags.

• Multi-Bag Cages

  Multi-bag cages can hold two or more filter bags, depending on the configuration. They are suitable for handling higher volumes of dust or larger particles. Additionally, multi-bag cages increase filtration efficiency by allowing the use of multiple filters simultaneously. This benefit can reduce downtime by extending the time between bag replacements.

  Multi-bag cages come in different variations. Inline bag cages are the most common. They typically feature a row of cylindrical cages positioned horizontally, holding multiple filter bags in a straight line. Inline bag cages work well for applications with higher dust volumes, maximizing filtration surface area.

  Another popular type is the staggered multi-bag cage. It has an alternating pattern of filter bags. This design reduces the width of the cage while increasing its length. The staggered arrangement boosts the filtration area, making it suitable for processing finer particulate matter. Additionally, staggered multi-bag cages improve dust collector airflows.

• Troughed Cages

  Troughed bag cages have a curved bottom section. This design helps to evenly distribute the dust collector's airflow across the filter bag. Troughed bag cages minimize the chances of excessive airflow penetration around a single bag, which can lead to bag blowouts. They also improve filtration efficiency by promoting consistent filtration throughout the entire filter.

• Extended Length

  These cages are longer than the typical cage designs. Depending on the configuration, they can have as much as 12 or more inches to an ordinary cage length. Extended-length bag cages are ideal for dust collectors with deeper hoppers or longer filter chambers. They can enhance filtration performance by increasing the filtration area. Extended-length bag cages also improve dust collection efficiency, reducing the amount of fine particles that escape into the environment.

• Custom Bag Cages

  Custom bag cages are designed to meet specific requirements. They can be made in various shapes. For instance, they can come in elliptical, round, and square shapes. Also, manufacturers can construct them using different materials and coatings to suit unique filtration needs.

Specification and Maintenance of Industrial Filter Bag Cages for Air Dust Collectors

• Material

  Industrial filter bag cages are made with different materials. Galvanized filter bag cages are coated with zinc on steel for more strength. Stainless steel filter bag cages use stainless steel pipes that don't rust. Painted mild steel filter bag cages have a layer of paint for protection and longer life.

• Diameter

  The diameter of industrial filter bag cages shows how big the bottom is. The diameter usually ranges from 3” to 10” (76 to 254mm). The base is wider to hold more bags. Industrial filter bag cages with bigger diameters can carry more filter bags.

• Length

  Industrial filter bag cage length refers to how tall the cage is. This also relates to the number of filter bags it can hold. Height can vary from 15” to 90” (381 to 2286mm) or more. Short filter bag cages work well in collectors with limited space. Taller ones are better for more extensive dust collection systems.

• Top/Framing

  The Framing/Top of an industrial filter bag cage is its top part. It can be round, conical, or with other shapes. The Framing/Top holds the filter bag firmly during operation. Round cages are more common. Some have a cone shape or other forms to meet specific machines.

Proper maintenance will help the industrial filter bag cage last a long time. Follow these tips to clean and care for it:

• Check the filter bag cage often and look for signs of damage like cracks or breaks. Fix or replace anything that is broken right away.
• Clean the filter bag cage regularly. Remove any dust or debris that collects over time. This will prevent blockages and keep airflow strong.
• Make sure the industrial filter bag cage is properly supported inside the dust collector. Use brackets or clamps as needed, so it does not move around while operating. This helps avoid damages. The industrial filter bag cage must be secure and stable.
• Keep the area around the dust collector free from materials and objects. Do not let anything come too close, so there is a good space around it. This helps air compactness and flow.

Scenarios of industrial filter bag cage air dust collectors

The usage scenarios for dust collector filter cages are widespread in the industrial field.

• Cement production plants:

  The production of cement will generate a lot of dust, which will affect the air quality and the health of workers. By using cage design filter bags, the plant can effectively reduce dust emissions, improve the working environment, and comply with environmental regulations.

• Chemical manufacturing:

  In the chemical industry, a wide variety of chemicals are handled, some of which may produce fine particulate chemicals or toxic substances that threaten employee safety and health. The filter bag can efficiently capture these harmful particles, protecting the health and safety of workers.

• Food processing:

  In food manufacturing, keeping the processing and facilities free from dust and contaminants is critical. The filter bags assist in removing airborne dust and impurities, ensuring product quality and adherence to stringent hygiene standards.

• Textile factories:

  Fiber and dust generated in the textile production process can pose fire hazards and affect product quality. The filter bags help control dust levels within the factory, improving air quality and reducing fire risks.

How to choose industrial filter bag cage air dust collectors

• Dust Characteristics Analysis:

  Understand the industrial users' specific dust nature, such as particle size distribution, bulk density, humidity, temperature, and chemical properties. The过滤袋笼设计适当的选择可帮助分析尘埃特征，以确保所选择的袋子能有效收集尘埃。

• Airflow and Filtration Area Calculation:

  Based on industrial users' equipment specifications and dust collection air volume, calculate the required filtration area. Ensure that the过滤袋笼选购has enough filtration area to meet处理能力的需求。

• Material Selection:

  Choose suitable过滤袋材料based on temperature, humidity, and chemical properties. For high温度环境用户可以考虑涤纶或玻璃纤维等耐高温材料。对于潮湿和潮湿的情况，用户可能需要使用抗真菌和抗霉菌的防潮袋。.'

• 用户设备兼容性：

  确保所选过滤袋笼与用户现有设备兼容，包括其尺寸、连接方式和其他技术要求。对下订单的用户进行全面的袋笼审核，以确保其功能。

• Quality and Service Provider Selection:

  选择高质量的过滤袋生产商，以确保其产品的质量和可靠性.明确规格和需求，与生产商或服务提供商进行沟通，选择适合的过滤袋和过滤框，确保设备的正常和有效运行.

Q & A

Q1 What is an air filter bag collector made of?

Industrial air filter bag collectors are made with different materials, depending on the type of air they will help filter. Polyester is the most common material because it is less expensive and offers good performance. However, other materials like polypropylene, nylon, fibreglass, P84, or aramid can be used for specific filtering needs.

Q2 How does a dust collector filter bag work?

The dust collector filter bag works by taking in and storing the powdery dust generated while carrying out industrial processes. However, once the bag is fully used, it can be filtered again with the help of a baghouse.

Q3 Are filter bags for dust collectors are expensive?

Filter bags for dust collectors aren't expensive. For small-scale dust collectors, filter bags will likely cost between $15 to $200. However, industrial-scale dust collectors will require more expensive filter bags. For industrial bags, it will likely cost $150 to $5000.

Q4 How can boost the dust collector's performance?

It is possible to improve the performance of a dust collector by selecting the right filters. Choosing the right sizing is also important. If possible, one should consider the elimination of static pressure losses to enhance the performance of the dust collector.
