How De-Sander Cyclone Works

Author:


De-Sander Cyclone is a dry-type gas-solid separation equipment that uses the centrifugal force generated by the gas-solid mixture when it rotates at high speed to separate the dust from the airflow.

De-Sander Cyclone is a dry-type gas-solid separation equipment that uses the centrifugal force generated by the gas-solid mixture when it rotates at high speed to separate the dust from the airflow. Since the centrifugal force suffered by the particles is much greater than the gravity and inertial force, the separation efficiency is high.

The main structure of the commonly used (tangential flow) tangential introduction De-Sander Cyclone separation is a conical cylinder, a gas inlet pipe is installed in the tangential direction of the upper part of the cylinder, and an exhaust pipe inserted into the cylinder to a certain depth is installed on the top of the cylinder. There is a powder outlet for receiving fine powder at the bottom of the cone. When the dust-laden airflow enters the cyclone separator from the intake pipe at a speed of 12-30m/s, the airflow will change from linear motion to circular motion. Most of the swirling air flows along the wall from the cylinder in a spiral downward direction toward the cone. In addition, the particles are thrown towards the wall under the action of centrifugal force. Once the dust particles contact the wall, they lose the inertial force, and rely on the momentum of the downward axial velocity near the wall to fall along the wall and enter the ash discharge pipe. Fall into the collection bag from the powder outlet. The rotating and descending external swirling air flow continuously flows into the center of the separator during the descending process, forming a centripetal radial air flow, and this part of the air flow constitutes an upward rotating internal swirling flow. The direction of rotation of the inner and outer swirls is the same. The manufacturer of De-Sander Cyclone tells you that the final purified gas passes through the exhaust pipe, and a part of the finer dust particles that have not been separated also escape. Another small part of gas flowing in from the intake pipe passes through the top cover of the cyclone separator and flows downward along the outside of the exhaust pipe. When it reaches the lower end of the exhaust pipe, it merges with the rising internal swirling airflow and enters the exhaust pipe. The fine particles dispersed in this part of the upcycled air flow are also carried away and subsequently collected by bag filters or wet dust collectors.
The purified natural gas enters the cyclone separation area of the equipment through the equipment inlet. When the impurity gas enters the cyclone separation tube along the axial direction, the airflow is strongly rotated by the guide vane, and the airflow spirals downward along the cylinder and enters the cyclone. Liquid droplets and dust particles with high density are thrown towards the wall of the device under the action of centrifugal force, and under the action of gravity, they fall along the wall of the cylinder and flow out of the dust outlet of the cyclone tube to the liquid storage area at the bottom of the equipment. flow out. The manufacturer of De-Sander Cyclone tells you that the rotating air flow shrinks in the cylinder and flows towards the center, forming a secondary vortex upward, flowing through the air guide tube to the purified natural gas chamber, and then flowing out through the top outlet of the equipment.
