Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a novel cyclone plate purification tower. Background Art

[0002] The main working mechanism of the cyclone plate tower is the inertial collision of dust particles and droplets, centrifugal separation and liquid film adhesion. The cyclone plates in the cyclone tower have a large opening rate and allow high-speed airflow to pass through, so they have a high load, a large processing capacity, and a large operating flexibility. The gas-liquid contact time is short, which is suitable for the process of gas phase diffusion control, such as the cyclone plate demisting system for printing waste gas treatment disclosed in a Chinese patent (publication number: CN210964278U). The patented technology includes a fixed ring and a plurality of blades, and the plurality of blades are radially arranged in the fixed ring, and the outer end is fixedly connected to the fixed ring, and the inner end extends to the center of the fixed ring; the side edges of the plurality of blades are overlapped in sequence to form a fish scale structure, and a gap is set between any two adjacent blades. This technical solution can effectively reduce harmful mist contained in the exhaust gas by adsorbing the water mist through the contact of the blades with the water mist in the exhaust gas. However, the fixed blade arrangement cannot meet the needs of various working scenarios well. When the intake pressure is low, the relative pressure drop is large due to the obstruction of the blades, which can easily cause poor exhaust or smoke backflow. Or when the intake pressure is high, the excessive intake pressure causes the gas flow rate to be too fast, resulting in insufficient gas purification, which will increase the purification pressure of the back-end purification equipment.
