During the oil exploitation process, the dust composition is complex, which may contain rock particles, metal debris and sticky substances, etc. These dusts are easily deposited on the pipe wall during the dust collection process due to the change of airflow velocity in the pipe and the friction force of the pipe wall. Especially the sticky dusts, they will adhere to the inner wall of the pipe. With the passage of time, the dust layer thickens, resulting in a decrease in the effective cross-sectional area of the pipe and an increase in airflow resistance. In severe cases, the pipe may be completely blocked, making the dust collection device unable to work normally.
