FW Series cyclone water separator

The cyclone water separator is a device used for the separation of gas-solid systems or liquid-solid systems.

It is widely used in the pharmaceutical industry to collect dust with a diameter of 5-10μm and above.

Due to the high dust concentration, it is under high temperature and high pressure conditions. It is also often used as an internal separation device or pre-separator in a fluidized bed reactor.

It has the advantages of simple structure, flexible operation,  high efficiency, convenient management and maintenance, and low price.

3, Service life: The design service life of the cyclone separator is not less than 20 years.

working principle

The cyclone separator uses the centrifugal force generated by the gas-solid mixture in the high-speed rotation process to separate dust from the airflow.

Because the centrifugal force of the particles is much greater than the gravity and inertial force, the separation efficiency is high. Its main structure is a cone-shaped cylinder and a cylinder. The upper part is equipped with an intake pipe in the tangential direction.

The top of the cylinder is equipped with a certain depth of cylinder. The exhaust pipe has a powder outlet at the bottom of the cone for receiving fine powder.

When the airflow is filled with dust, the airflow is 12-30m When the speed of /s enters the cyclone separator from the intake pipe, the airflow will change from linear motion to circular motion.

Most of the swirling air flows down the wall from the cylinder to the cone.

In addition, the particles are thrown to the wall under the action of centrifugal force. Once the dust particles contact the wall, they will lose their inertial force.

The momentum of the downward axial velocity near the wall will drop along the wall and enter the ash discharge pipe, from the powder outlet. Drop into the collection bag.

The downwardly rotating downwardly rotating external swirling air flow continuously flows into the central part of the separator during the descending process to form a centripetal radial airflow, and this part of the airflow constitutes an upwardly rotating upward internal swirling flow.

The direction of rotation of the inner swirling flow and the outer swirling flow are the same. Finally, the purified gas is discharged out of the exhaust pipe, and some fine dust particles that have not been separated will also escape.

Another small part of the gas flowing in from the intake pipe passes through the top cover of the cyclone separator and flows down to 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 scattered in this part of the upper cyclone are also taken away, and then collected by a bag filter or a wet dust collector.

The purified natural gas enters the cyclone separation zone in the equipment through the equipment inlet.

When the impurity gas enters the cyclone separation tube in the axial direction, the airflow is guided by the guide blade to generate a strong rotation, and the airflow spirally enters the cyclone water separator barrel downward.

Under the action of centrifugal force, dense liquid droplets and dust particles are thrown on the wall, and fall along the cylinder wall under the action of gravity and flow from the dust outlet of the cyclone tube to the bottom of the liquid storage area.

The liquid from the bottom of the equipment The outlet at the bottom of the device flows out. The rotating airflow shrinks and flows to the center of the cylinder, forming a secondary vortex upward, which flows through the air pipe to the purified natural gas chamber, and then flows out through the outlet on the top of the equipment.
