Introduction Working Principle of Cartridge Filter Through a combination of Brownian diffusion and sieve filtration, dust accumulates on the surface of the filter material. After being purified, the clean air exits through the exhaust pipe into the atmosphere. As the dust layer thickens, the resistance of the filter increases. Once a set threshold is reached, the system interrupts the airflow, opens the electromagnetic pulse valve, and uses compressed air to expand and vibrate the filter cartridges, dislodging the dust. The collected dust then falls into the ash hopper and is discharged via the discharge valve. Applications Structure and Components (1) The filter cartridges are composed of an outer layer, inner layer, and middle layer. The inner and outer layers are covered with metal mesh or hard plastic net, while the middle layer is folded filter material. A sub-micron ultra-thin fiber layer is attached to the filter material, with fiber gaps ranging from 0.12 to 0.6 micrometers. This design significantly increases the effective filtration area, making the cartridge highly efficient. (2) The cabinet serves as the housing of the dust collector, including the gas tank and ash hopper. The gas tank provides the necessary space for cleaning, ensuring even airflow distribution. The ash hopper collects the filtered dust. (3) The ash removal mechanism includes the blowpipe, pulse valve, and air bags. When dust accumulates on the filter cartridges, the system initiates a cleaning cycle. Compressed air is blown through the pulse valve, causing the cartridges to expand and vibrate, dislodging the dust. The collected dust is then discharged through the ash hopper.

A cartridge filter is a type of dust collection system that uses filter cartridges as the primary filtering element. Based on the principles of pulse bag filters, it represents an advanced solution for air purification and industrial powder (smoke) dust removal. With high air volume (over 99.5%), low pressure requirements (0.2–0.6 MPa), and low resistance loss (800–1000 Pa), this system is highly favored by users. The cartridge filter is known for its advanced technology, compact design, compliance with emission standards, small footprint, low investment, and minimal operating costs.
The cartridge filter consists of several key components: the cabinet, filter cartridges, and the cleaning system. When dusty gas enters the dust collector, the sudden expansion and air distribution plate cause coarse particles to settle in the ash hopper due to gravity and inertia. Fine particles are then captured in the filtration chamber.
This type of cartridge filter is suitable for various applications, including dust removal at the inlet of blast furnace blowers, oxygen generators, air compressors, control rooms, clean workshops, public building HVAC systems, and low-concentration flue gas treatment. As materials and dust removal technologies continue to evolve, the application scope of cartridge filters is expanding. Today, they are widely used in industries such as construction materials, metallurgy, power generation, food processing, and chemicals. They are gradually replacing traditional bag filters and electrostatic precipitators.
The system mainly consists of three parts: the filter cartridges, the cabinet, and the ash removal mechanism.

Asphalt heating storage equipment is mainly composed of heating device, storage tank and control system. The heating unit uses oil or gas burners to transfer heat to the asphalt to heat it to the proper temperature. Storage tanks are large containers used to store heated asphalt, generally made of high-temperature resistant materials. The control system is responsible for monitoring the operating status of the equipment and the temperature of the asphalt to ensure the safe and stable operation of the equipment.
The heating principle of asphalt heating storage equipment is to transfer heat to asphalt through thermal conduction, so that it is heated. Heating devices are generally divided into direct heating and indirect heating in two ways. Direct heating is the use of the burner directly into the storage tank, hot air through the contact of hot air with the asphalt to heat it. Indirect heating is the use of heat exchangers to heat the asphalt in the storage tank without direct contact with the air. The two heating methods have advantages and disadvantages, and need to be selected according to the actual situation.
Asphalt heating storage equipment heating speed, can quickly heat asphalt to the use of temperature, improve production efficiency. At the same time, the equipment also has environmental protection characteristics, reducing exhaust gas and smoke emissions, reducing the impact on the environment. In addition, the operation of asphalt heating storage equipment is simple and easy to maintain, which can meet the needs of various road construction and maintenance projects.
In short, asphalt heating storage equipment is an important road construction equipment, with high efficiency, safety, environmental protection and other characteristics. It can provide a stable supply of asphalt for road construction, improve construction efficiency, reduce the impact on the environment and waste of resources. The equipment has a wide application prospect in the field of road construction.
