Description

A cyclone dust collector device

technical field

The utility model belongs to the technical field of separation operations, and relates to a cyclone dust collector device for gas-solid separation of dust-containing gas produced in metallurgy, chemical industry, environmental protection and other fields, especially blast furnace gas.

Background technique

Today, environmental protection has become a worldwide problem. The Air Pollution Index is also increasingly becoming an important information to guide people's daily life. The concentration of total suspended particulate matter in the air has also become an important index to measure the air pollution index. We have done a lot of work on how to reduce the suspended particulate matter in the air, especially the control of dust emission in metallurgy, chemical industry and other fields. The investment of dust accumulators, cleaners and other devices has effectively purified the dusty gas before it is discharged into the atmosphere, making outstanding contributions to the cause of environmental protection. At present, the dust collectors used for gas-solid separation mainly include gravity dust collectors, cyclone dust collectors, washing towers, bag dust collectors, etc., and the efficiency of the dust collectors is also different. Cyclone dust collector has been widely researched and applied due to its excellent dust removal efficiency, small footprint and low investment. At present, cyclone dust collectors are mainly divided into two types: axial cyclone dust collectors and tangential cyclone dust collectors. Although the cyclone dust collector has many advantages, there are also several common problems. The deflector and the casing at the deflector are severely worn, or the swirl arm, the swirl arm and the connection between the swirl arm and the cylinder are severely worn. The resulting equipment operation and maintenance costs will also increase.

Utility model content

The purpose of this utility model is exactly to overcome the deficiency of prior art, proposes a kind of cyclone dust collector device. The utility model has small resistance loss and impact when the airflow flows through the deflector, and the efficiency of the equipment dust collector is high, which can effectively reduce the dust content in the outflow gas, reduce environmental pollution, reduce the load of subsequent dust removal facilities, and reduce investment and operation costs . It is used for gas-solid separation of dust-containing gas produced in metallurgy, chemical industry, environmental protection and other fields, especially blast furnace gas.

The technical scheme adopted by the utility model is as follows: the cyclone dust collector device includes an intake pipe, a cyclone dust removal chamber, a reflection cone and an exhaust pipe, and is characterized in that: a deflector and a flow guide cone are arranged in the cyclone chamber of the dust collector; The deflector is arc-shaped; the angle between the deflector and the horizontal plane is 20°-75°; the angle between the deflector cone and the horizontal plane is 20°-75°; the deflector is evenly arranged on the circumference of the swirl chamber ; The number of deflectors is 4-30; a reflective cone is set in the storage room, and the included angle between the reflective cone and the horizontal plane is 45°-75°.

The dust-laden gas enters the swirl chamber through the intake pipe, and through the combined action of the diversion cone and the deflector, the airflow generates tangential and axial velocities and enters the swirl dust removal chamber. The dust particles in the airflow are affected by centrifugal force It moves toward the wall of the dust collector, and slides down along the wall under the action of its own weight and airflow. The accumulated dust will eventually fall into the storage room at the bottom, and the dust will be discharged by setting the ash discharge chamber. The air flow is redirected under the action of the reflective cone, forming an upper swirling air flow (inner swirling flow) to be discharged through the middle exhaust pipe.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in the figure: the utility model is composed of an intake pipe 2, a swirl dust removal chamber 5, a swirl chamber 7, a storage chamber 6, etc., and a deflector 4 and a deflector cone 3 are arranged in the swirl chamber 7. The deflector 4 is arc-shaped and forms an angle of 45° with the horizontal plane, and the deflector 4 is evenly arranged on the circumference of the swirl chamber 7, and the number of the deflector is 24; the arc design of the deflector 4 reduces the airflow The resistance loss and frontal impact after contact with the deflector 4; on the one hand, the deflector 4 makes the airflow have a tangential velocity, which makes the dust generate centrifugal force; on the other hand, it makes the airflow generate an axial velocity, so that the airflow and dust move downward . The angle between the diversion cone 3 and the horizontal plane is 30°, which guides the airflow to move downward. A reflective cone 11 is arranged in the storage chamber 6, and the included angle between the reflective cone 11 and the horizontal plane is 60°, which guides the air flow to move upward; the upper swirling air flow 10 is discharged from the exhaust pipe 9.

The dust-laden gas 1 enters the swirl chamber 7 through the intake pipe 2, and through the joint action of the diversion cone 3 and the deflector 4, the airflow generates tangential and axial velocities, and enters the swirl dust removal chamber 5. Due to centrifugal force, the dust particles move towards the wall of the dust collector, and slide down along the wall under the action of its own weight and air flow. The accumulated dust 8 finally falls into the storage room 6 at the bottom, and the ash is discharged by setting the ash discharge chamber; the air flow is Redirected under the action of the reflecting cone 11, the upper swirl air flow 10 (inner swirl flow) is formed and discharged through the middle exhaust pipe 9.

The utility model has the advantages of cleanliness, environmental protection and high efficiency. It is an effective dust removal device for dusty gas, especially blast furnace gas.
