1、 Analysis of the causes of dust blockage in high-pressure pulse bag filter
Dust properties: The properties of dust have a significant impact on the operation of high-pressure pulse bag filters. If the dust contains high levels of moisture or sticky substances, it is easy to adhere to the surface of the filter bag, leading to clogging of the filter bag.
Improper operation: Improper operation by operators may also lead to dust blockage. For example, during the operation of the equipment, if the cleaning time interval is set too long or the cleaning pressure is set too low, it can cause excessive accumulation of dust on the surface of the filter bag, ultimately leading to dust blockage.
Equipment malfunction: Some malfunctions of the high-voltage pulse bag filter itself may also cause dust blockage. For example, if components such as pulse valves and fans malfunction, it can affect the normal operation of the equipment and may also cause clogging of the filter bags.
2、 A method for dealing with dust blockage in high-pressure pulse bag filter
Adjusting operating parameters: Depending on the nature of dust and equipment operation, the cleaning time interval, cleaning pressure, and other operating parameters can be adjusted. For example, if the moisture content of dust is high, the cleaning time interval can be appropriately shortened and the cleaning pressure can be increased; If the dust has a high viscosity, the cleaning time interval can be increased and the cleaning pressure can be appropriately reduced.
Replacing the filter bag: If the problem of clogging is severe, it can be considered to replace the filter bag. When replacing filter bags, filter bag materials with anti adhesive and easy to clean properties should be selected, such as polyester fiber, acrylic, etc. At the same time, the replacement process recommended by the manual or manufacturer should be followed to ensure the quality of the replacement.
Check for equipment malfunctions: In response to the problem of clogging caused by equipment malfunctions, troubleshooting and maintenance should be carried out. For example, checking whether components such as pulse valves and fans are working properly; Check for leaks in the air duct; Check if there are any other abnormal situations inside the device. Once a malfunction is found, it should be repaired or replaced in a timely manner.
Strengthen equipment maintenance: In order to prevent the occurrence of dust blockage problems, daily maintenance and upkeep of equipment should be strengthened. For example, regularly check the wear and tear of filter bags, and promptly repair or replace damaged filter bags; Regularly clean the accumulated dust inside the equipment to maintain its cleanliness and hygiene; Regularly inspect the air supply system of the equipment to ensure its stability and adequacy.
Training operators: Improper operation by operators is one of the causes of ash blockage problems. Therefore, professional training should be provided to operators to enhance their operational skills and sense of responsibility. The training content includes the basic principles of equipment, operating procedures, safety precautions, etc. Through training, operators can use and maintain high-pressure pulse bag filters correctly, reducing the occurrence of clogging problems.
