Description

TECHNICAL FIELD

[0002] The cement cyclone is an important equipment in the cement production line, which is mainly used for separating dust and particulate matter in the cement production process to ensure that the relatively clean gas is discharged into the atmosphere. The cement cyclone mainly consists of an air inlet, a cyclone body, a discharge pipe and an exhaust pipe. The cement cyclone is a device designed based on the mechanical principle of gas cyclone. After the gas enters the cyclone through the air inlet, it rotates in the cyclone body to form a high-speed rotating gas cyclone. Dust and particulate matter are separated to the inner wall of the cyclone under the action of cyclone force, and slide down to the discharge port to fall into the mill or other collection devices. The purified gas is discharged outside the system through the exhaust pipe. However, in the current production process, as the production increases, the wind speed also increases, which easily causes vortex due to the impact of the inlet air flow on the cyclone in the cyclone, seriously affecting the system operation stability, causing high energy consumption, and affecting the production.
