Description

Technical Field

[0001] The utility model relates to the field of sulfuric acid production equipment, in particular to a demisting device for sulfuric acid production. Background Art

[0002] The working principle of the demister for electronic grade sulfuric acid is: the SO3 at the bottom is converted into gas by heating. When the gas rises and passes through the wire mesh in the demister, the droplets (containing impurities) entrained in the gaseous SO3 will be blocked by the wire mesh and fall back into the evaporator at the bottom of the demister, preventing the droplets from being entrained into the rear-end product.

[0003] At present, the existing defogger has two sections, upper and lower. During the process of SO3 evaporating upward, the gas SO3 tends to concentrate in the middle of the wire mesh, making the utilization efficiency of the surroundings of the wire mesh very low, resulting in great waste.
