Cartridge filters are advanced dust collection systems that use filter cartridges as the primary filtration element. They are an innovative solution for air and industrial powder (smoke) dust removal, built upon the principles of pulse bag filters. These systems offer high air volume (over 99.5% efficiency), low operating pressure (0.2–0.6 MPa), and low resistance loss (800–1000 Pa), making them highly efficient and user-friendly. With their advanced technology, compact design, and low investment and operating costs, cartridge filters are ideal for a wide range of industrial applications.
A typical cartridge filter consists of a cabinet, filter cartridges, and an injection system. When dusty gas enters the dust collector, it passes through an air distribution plate, allowing larger particles to settle in the ash hopper due to gravity and inertia. The finer particles then enter the dust filtering chamber, where they are captured by the filter material through mechanisms like Brownian diffusion and sieve filtration. As dust accumulates on the surface of the filter, the resistance increases. Once a certain threshold is reached, the system interrupts the airflow, opens the electromagnetic pulse valve, and uses compressed air to clean the filter cartridges. This causes the cartridges to expand and vibrate, dislodging the dust, which falls into the ash hopper and is discharged through the discharge valve.
Cartridge filters are widely used in various industries such as steel, power generation, food processing, and chemical manufacturing. They are particularly suitable for dust removal at the inlet of blast furnace blowers, oxygen generators, air compressors, control rooms, clean workshops, and public building HVAC systems. Their ability to handle low concentration flue gases makes them a versatile and efficient alternative to traditional bag filters and electrostatic precipitators. As materials and dust removal technologies continue to evolve, the application of cartridge filters is expanding further.
The main components of a cartridge filter include the filter cartridges, the housing, and the ash removal mechanism. The filter cartridges are made of multiple layers: an outer layer, inner layer, and a folded middle layer. The outer and inner layers are typically covered with metal mesh or hard plastic nets, while the middle layer is made of foldable filter material. A sub-micron ultra-thin fiber layer is attached to the general filter material, enhancing filtration efficiency with very tight fiber spacing (0.12–0.6 μm). This design significantly increases the effective filtration area.
The housing serves as the outer shell of the dust collector, containing the gas tank and ash hopper. The gas tank provides space for cleaning and ensures even airflow distribution, while the ash hopper collects the filtered dust.
The ash removal mechanism includes components such as the blowpipe, pulse valve, and air bags. When dust builds up on the filter cartridges, the system initiates a cleaning cycle. Compressed air is directed through the pulse valve, causing the filter cartridges to expand and vibrate, removing the accumulated dust. The dust then falls into the ash hopper and is discharged through the discharge valve.

Mobile asphalt mixing plant is mainly composed of mixing host, dosing system, fuel system, support device and dust removal system. Among them, the mixing machine is the core part, which is responsible for mixing various raw materials evenly to produce high-quality asphalt mixture. The dosing system is responsible for adding various raw materials to the mixing machine in a certain proportion. The fuel system powers the entire device, usually using diesel or gasoline. The support unit includes four wheels and a suspension system that allows the device to travel and operate in a variety of terrain conditions. The dust removal system is responsible for collecting dust and exhaust gas generated during the production process to ensure a clean working environment and air quality.
The working process of the mobile asphalt mixing station mainly includes the following steps: First, the various raw materials are prepared and added to the mixing machine through the dosing system. Next, the mixer machine starts to work, mixing the raw materials evenly to produce the asphalt mixture. The asphalt mixture is then transported to the construction site for road paving or maintenance. In the whole process, the operation of the mobile asphalt mixing plant is simple and convenient, and it can be quickly deployed and moved, which greatly improves the construction efficiency.
Compared with the traditional fixed asphalt mixing plant, the mobile asphalt mixing plant has the following advantages: First, it has the characteristics of strong mobility and rapid deployment, and can adapt to a variety of complex terrain and construction environment. Secondly, the installation and disassembly of the mobile asphalt mixing plant is very convenient, and the transfer and installation of the equipment can be quickly completed, reducing the construction time. In addition, the operation of the mobile asphalt mixing plant is simple and easy to maintain, reducing the skill requirements of the operator and maintenance costs.
In short, the mobile asphalt mixing plant is an efficient, convenient and mobile asphalt mixture production equipment, which is suitable for all kinds of road construction and maintenance projects.
