Problems solved by technology
However, in the multi-tube spiral demist and dust removal system provided in the prior art, the dust in the slurry that is continuously hit by the water film formed on the inner wall can easily cause the outer cylinder 5 and the spiral blade 7 of the demist and dust removal system to stick together. As a result, it will cause blockage and cannot meet the long-term stable operation requirements

The utility model relates to a pneumatic cyclone combined defogging device, which belongs to the technical field of desulfurization. The pneumatic cyclone combined demisting device includes N pneumatic cyclone demisting units installed in parallel, the upper sealing plate and the lower sealing plate. The plates are sealed and connected together, N is an integer greater than or equal to 1, and each pneumatic cyclone demister unit includes a filter cartridge. The invention provides a pneumatic swirling combined defogging device, which increases the degree of gas-liquid separation; reduces the concentration of mist droplets at the outlet of the mist eliminator; reduces the loss of water; avoids the secondary pollution of the air caused by harmful substances in the droplets; The secondary carrying of droplets is greatly reduced; the removal efficiency is high.
Description
technical field [0001] The invention relates to a pneumatic cyclone combined defogging device, which belongs to the technical field of desulfurization. Background technique [0002] Among flue gas desulfurization technologies, wet desulfurization technology is the most widely used. Its core equipment is the absorption tower, and the flue gas washed by the absorption tower will contain a large number of liquid droplets, which will be discharged with the flue gas. At the same time, the dissolved and suspended particles in the droplets will also be discharged into the atmosphere together, causing secondary pollution of the air. [0003] In order to reduce the discharge of liquid droplets in the flue gas, the existing technical method is to install a mist eliminator on the top of the absorption tower. Most of the existing demisters are in the form of folded plates, and their demisting effect is better. However, at medium and low operating loads, due to the slow flow of flue ga...
