Pulse Bag Dust Collector Mobile Single Filter Cartridge Reverse Blow Dust Collector Industrial Grinding and Polishing Dust Removal Equipment

Baghouse dust collectors are essential air purification equipment, primarily used to remove dust and particulate matter generated during industrial production processes. The following is a detailed introduction to baghouse dust collectors:

I. Working Principle

A baghouse dust collector is a dry dust removal device suitable for capturing fine, dry, non-fibrous dust. Its working principle is as follows: when dust-laden gas enters the baghouse dust collector, larger and heavier dust particles settle due to gravity and fall into the ash hopper. The gas containing finer dust passes through the filter material, where the dust is trapped, purifying the gas. The dust removal efficiency of new filter media is typically not high initially. However, after a period of use, a layer of dust accumulates on the surface of the filter bag due to sieving, collision, retention, diffusion, electrostatic effects, and other mechanisms. This layer of dust is called the primary dust layer. Relying on the function of this primary layer, even filter media with larger pores can achieve high filtration efficiency.

II. Main Features

1. High-Efficiency Dust Removal: Baghouse dust collectors utilize advanced filtration technology to efficiently capture fine particulate matter in the air, with dust removal efficiency generally exceeding 99%.
2. Large Air Handling Capacity: Baghouse dust collectors have a high gas processing capacity, making them suitable for production enterprises and industrial facilities of various scales, with a wide range of air volume handling capabilities.
3. Stable and Reliable: Baghouse dust collectors are designed and manufactured with stable and reliable processes, enabling long-term stable operation and extended equipment lifespan. Additionally, they exhibit excellent high-temperature resistance and corrosion resistance, allowing them to adapt to various harsh working environments.
4. Easy Maintenance: Maintenance and cleaning of baghouse dust collectors are relatively straightforward, requiring only periodic cleaning and replacement of filter bags. Moreover, their compact structure and small size result in a smaller footprint, facilitating easy installation and maintenance.

III. Selection Principles

The selection of a baghouse dust collector is primarily based on technical parameters, including air volume, gas temperature, dust concentration, and humidity. According to the maximum values of air volume, gas temperature, and dust concentration specified in the process design, the corresponding dust collector model is selected based on the principle of being slightly lower than the values in the technical performance table. Additionally, factors such as air consumption and compressed air usage must be considered.

IV. Application Areas

Baghouse dust collectors are widely used across various industries and fields, including manufacturing, coal industry, cement and building materials industry, chemical and pharmaceutical industry, food processing industry, and flue gas treatment. In the manufacturing industry, baghouse dust collectors are commonly used for dust treatment in processes such as metal processing, mechanical processing, automotive manufacturing, and electronics manufacturing. In the coal industry, they are employed for the removal of coal dust and smoke dust in coal mines and thermal power plants. In the cement and building materials industry, they are used for dust treatment in processes such as cement production, limestone crushing, and concrete mixing.

V. Technical Parameters

The technical parameters of baghouse dust collectors include model, processing air volume (m³/h), total filtration area (m²), filtration velocity (m/min), number of filter bags (units), equipment resistance (Pa), inlet dust concentration (g/m³), and outlet emission concentration (mg/m³). These parameters are crucial for selecting the appropriate baghouse dust collector.

In summary, baghouse dust collectors have become important equipment in the field of industrial environmental protection due to their high-efficiency dust removal, large air handling capacity, stability, reliability, and ease of maintenance. They play a vital role in industrial settings where dust and particulate matter need to be handled.
