Common Abnormalities and Solutions for Cartridge Dust Collectors
Issue: Cutting The Surface
Impact:
Dust can directly enter the exhaust system through the damaged areas, leading to a significant increase in emission concentration, making it impossible to meet environmental discharge standards. This negatively affects the entire dust collection system and production.
Cause Analysis:
1. Improper Operation:
a. Incorrect Installation: If the filter element is installed in the wrong direction, inaccurate position, or not securely fixed, it can result in uneven stress on the filter element, causing it to rub against other components and become damaged.
b. Excessive Cleaning: Using tools to clean the filter element can damage its fibers, leading to breakage.
c.Improper Handling: During unpacking or transportation, the filter element may come into contact with sharp objects, causing cuts or tears.
2. Impact of Dust Particles:
a. Hard Dust: Hard and coarse dust particles cause significant wear on the filter element, making it prone to tearing.
b. Moist or Sharp Dust: These types of dust can directly damage the filter structure of the filter element.
3. Equipment Manufacturing Issues:
a. Installation Problems: Issues such as misaligned pulse jet pipes, excessive pulse pressure, or overly frequent pulse cleaning can lead to filter element damage.
b. Filter Element Material Issues: If the material of the filter element is not suitable for the application, such as being prone to wear or chemical corrosion, it can tear more easily during use.
c. Structural Issues: Problems with the equipment structure, such as poorly sealed joints, welds, or airflow design, can cause turbulence, leading to erosion and damage to the filter media.
Measures to Take:
1. Proper Installation:
Install the filter element strictly according to the operating procedures, ensuring the correct direction, position, and fixation method of the filter element.
2. Filter Element Material:
Select filter element materials that are wear-resistant and chemically resistant based on the characteristics of the dust and operating conditions.
3. Inspection and Replacement:
If filter element damage is found, immediately assess the extent of the damage. If the damage is severe, replace the filter element with a new one in a timely manner.
4. Adjust Operations:
Optimize the operational procedures to avoid excessive cleaning, and ensure correct installation and use of the filter element.
5. Improve Equipment:
Check the pulse jet system and the installation of the filter element. Adjust the direction and pressure of the pulse air to ensure even stress distribution on the filter element.
