Description

Technical Field

[0001] The utility model relates to the technical field of dust cleaning equipment for multi-tube cyclone dust collectors, in particular to dust cleaning equipment for multi-tube cyclone dust collectors. Background Art

[0002] The multi-tube dust collector is composed of multiple cyclone sub-mechanisms. The hot air furnace high-temperature and dust-laden airflow enters the cyclone dust collector cylinder from the air inlet pipe at a speed of 12-25m / s along the tangential direction, and spirals downward between the outer cylinder and the middle exhaust pipe. Inertial centrifugal force is generated during the rotation process; the dust particles are affected by the air flow on one side, rotating and falling in it; on the other side, they are affected by the centrifugal force and gradually spread outward and approach the cyclone dust collector cylinder wall; then they collide with the inner wall of the outer cylinder of the ceramic multi-tube dust collector, rotate and slide down along the inner wall, and are collected at the dust discharge port of the multi-tube cyclone dust collector at the middle bottom. The dust removal gas enters the upper part of the cyclone dust collector from the V body of the cyclone dust collector through the ceramic center tube and is discharged into the bag dust collector. The high-temperature dust-containing flue gas cools down rapidly when entering the cyclone, causing the moisture content of the dust to increase and block the cyclone sub-mouth. After the dust is collected in the V body of the cyclone dust collector, it is not easy to remove due to its fineness and moisture content, resulting in a decrease in the working efficiency of the cyclone dust collector. Therefore, a dust cleaning device for a multi-tube cyclone dust collector is provided. Utility Model Content
