Description

Technical Field

[0001] The present invention relates to the technical field of cyclone dust removal equipment, and more specifically to a Venturi cyclone multi-stage demisting wet dust removal unit. Background Art

[0002] The Venturi dust collector is a wet dust collector that achieves the purpose of dust removal by bringing the dust-laden gas into close contact with a liquid (usually water) and utilizing the inertial collision of water droplets and particles and other effects to capture particles or enlarge them. This process involves spraying water in the Venturi flow channel. When the dust-laden gas passes through the Venturi throat, the dust particles collide and agglomerate with the water droplets due to the water absorption effect to form larger particles, which then enter the cyclone dust collector with the air flow. The cyclone dust collector is mainly composed of a cylinder, a cone, an inner cylinder, an air inlet pipe, an exhaust pipe, etc. The dust-laden gas is introduced from the inlet into the space between the outer shell and the exhaust pipe of the dust collector to form a rotating downward external vortex. The dust suspended in the external vortex moves toward the wall of the device under the action of centrifugal force, and moves to the lower part of the dust collector with the external vortex and is discharged from the dust discharge hole. The purified gas An ascending internal vortex is formed and discharged through the exhaust pipe. In the Venturi cyclone dust removal combined device, the dust-laden gas first passes through the Venturi dust collector. The dust-laden airflow passing through the throat at high speed interacts with the injected water to form mist droplets. These droplets form larger water-carrying particles with the dust particles in the gas through collision and condensation. These particles then enter the cyclone dust collector with the airflow. In the cyclone separator, the dust-laden water droplets and airflow entering tangentially rotate at a certain flow speed on the inner wall of the cyclone dust collector. The particles gain centrifugal force in the rotation with the airflow and are thrown to the inner barrel wall of the cyclone dust collector, thereby being separated from the airflow. The separated particles and liquid flow to the storage tank below due to gravity. After the solid-liquid separation is achieved, the clear liquid returns to the throat where the Venturi is injected, and the mud slurry is discharged regularly.

[0003] However, the Venturi cyclone dust removal equipment under the existing technology still has the following shortcomings in actual use;

[0004] First, when the Venturi cyclone dust removal device under the prior art is in use, the separated particulate impurities and water in the storage tank at the bottom will be separated into solid and liquid by gravity sedimentation, and the upper clear liquid will be re-injected into the throat of the Venturi through the return pipe for reuse. However, when the storage tank is shaken by external force, the particulate impurities will surge upward and will be re-absorbed into the throat of the Venturi by the return pipe, thereby affecting its dust removal function. That is, the solid-liquid separation effect of the Venturi cyclone dust removal device under the prior art is not ideal;

[0005] Secondly, the existing Venturi cyclone dust removal equipment does not have the function of filtering, compressing and collecting the particulate impurities deposited at the bottom when in use, that is, the existing Venturi cyclone dust removal equipment does not fully process the collected mud impurities;
