1、 The working principle of the pulse filter cartridge dust collector is that the airflow containing wood chips is transported to the pulse filter cartridge dust collector through a fan; In the diversion chamber, the airflow velocity decreases under the action of the diversion plate, and heavier wood chips fall into the ash chamber under the action of gravity. Other lighter and finer dust particles are adsorbed on the outer surface of the filter bag along with the airflow. After being filtered by the bag, the clean gas enters the exhaust chamber and is discharged outside. As the filtration process continues, more and more dust will accumulate on the outer surface of the filter bag, which will correspondingly increase the operating resistance of the system and reduce the dust removal efficiency of the system. After setting the pulse amplitude and frequency, the system will automatically clean the filter bag during operation, thereby increasing the filtering efficiency and extending the service life of the pulse filter cartridge dust collector. 2、 Possible factors causing ignition of pulse filter cartridge dust collector: Rust dust in the pipeline of pulse filter cartridge dust collector will generate static electricity in high-speed airflow. Due to radiation, ion or electron adhesion, friction between dust particles or between dust and objects usually causes dust particles to carry charges. When rust dust flows in pipelines, it rubs against each other, and the friction between dust particles and the inner walls of pipelines and equipment can generate thousands of volts of electrostatic potential. At the same time, this type of dust has the characteristics of dispersion and suspension, with the dispersion increasing the friction area and the suspension causing the rust particles to come into contact but not continuously, resulting in an increasing electrostatic potential. When the accumulated potential increases to the breakdown field strength between dust particles, static sparks will be generated. When the discharge energy reaches or exceeds the small ignition energy of rust dust, a fire accident will occur. Experiments have shown that chemical fiber filter materials are usually places where static electricity is concentrated. The dust accumulated on the filter cartridge increases the strength of the spatial electric field. When the breakdown field strength between the dust accumulates, electrostatic spark discharge occurs, and its discharge energy is sufficient to ignite rust dust. The ignition of a pulse filter cartridge dust collector is a very serious problem with unimaginable consequences. In the early stage of designing a pulse filter cartridge dust collector, the flammable and explosive characteristics of dust should be considered and a feasible solution should be selected. 3、 The understanding of the filter cartridge of the pulse filter cartridge dust collector is related to the working efficiency of the pulse filter cartridge dust collector itself, which can be unanimously recognized and trusted by everyone. So, is the filter cartridge replaced by the pulse filter cartridge dust collector ordinary waste or dangerous goods? The answer is that it cannot be considered a dangerous item because there are various reasons for replacing the filter cartridge. It may be due to factors such as loose filter cartridge or broken filter screen that the pulse filter cartridge dust collector cannot work properly. However, this does not mean that the filter cartridge will be dangerous. We can treat the replaced filter cartridge as general solid waste. How often does the filter cartridge in the pulse filter cartridge dust collector need to be replaced? The specific situation depends on the user's working conditions. The filter cartridge should be replaced every 6-8 months, and the replacement time should be recorded when replacing the filter cartridge, so as to control the maintenance of the next filter cartridge replacement. If your welding smoke concentration is high and the continuous use period is long, the use time will naturally be shorter than the predetermined service life; In addition, if sparks still enter the filter cartridge from the welding smoke, the frequency of replacement will increase. So it is important to pay more attention to maintenance in daily life, as proper maintenance can extend the service life. 4、 What are the items that need to be checked for a pulse filter cartridge dust collector? The pulse filter cartridge dust collector is a very good dust collector equipment to use. If we want a good purification effect during use, we need to check the dust collector when using it in daily life. In fact, the inspection of the pulse filter cartridge dust collector is equivalent to the maintenance of the dust collector. Take cars as an example, the frequency of problems that may occur if we do regular maintenance and if we don't do regular maintenance is also different. Similarly, for pulse filter cartridge dust collectors, it is definitely not wrong to pay attention to maintenance during operation. Below are some routine inspections for pulse filter cartridge dust collectors. 1. Check the pressure reducing valve of the pulse filter cartridge dust collector: check if the pressure reducing valve leaks and if there are any debris inside the valve. 2. Check the pulse filter cartridge dust collector fan: The fan should be installed firmly and horizontally, and regularly lubricated with oil. 3. View/Guide Plate: Check for excessive wear or corrosion on the pulse filter cartridge dust collector or guide plate. 4. Inspect the air duct of the pulse filter cartridge dust collector: check for corrosion, leaks, or any external damage, loose bolts, welding cracks, and significant dust accumulation. 5. Check the compressed air system of the pulse filter cartridge dust collector: check whether the compressor is correctly filled with lubricating oil, whether there are cracks on the air bag and pipeline, and whether the air compressor and air bag are drained. 6. Check the maintenance doors of the pulse filter cartridge dust collector: All maintenance doors of the dust collector should be tightly sealed. Check if the sealing strip is loose, broken, or worn, and replace it as needed. 5、 Maintenance of Pulse Filter Cartridge Dust Collector Cartridge In recent years, various industrial developments have been carried out to prevent damage to the environment that people rely on for survival. Each factory needs to strictly comply with the call for environmental protection, jointly respond to environmental policies, and lay a foundation for the environment we rely on for survival. China is a heavy industrial country with countless factories such as cement plants and chemical plants. However, the pulse filter cartridge dust collector can precisely handle the dust generated by these factories. But there is one issue that needs our attention, which is that if the pulse filter cartridge dust collector is used for a long time, the filter cartridge is easily worn and damaged. Now let's take a look at the maintenance of the filter cartridge. 1. The filter cartridge should be cleaned regularly, requiring oil-water separation, and the air bag should be drained in a timely manner. Regularly check the opening and closing of the air ducts inside the dust collector, and control the air used for cleaning. Check the degree of blockage in the accessories. If mild blockage is found, it should be promptly removed, dried, and cleaned by tapping. Maintain normal ventilation capacity to avoid blockage and continue to operate in a vicious cycle. 2. Regularly check for air leaks in the exhaust gas treatment system, implement leak prevention measures, and provide external insulation for the exhaust gas system after grinding. 3. To maintain the ventilation capacity inside the mill at a stable and good level, once there is a change, the ventilation volume inside the mill can still be adjusted and maintained by the suction force of the exhaust fan.
