Description

technical field

[0001] The invention relates to the technical field of gas and liquid capture and separation, in particular to an aerosol capture and separation device and a method for gas and liquid capture and separation using the aerosol capture and separation device. Background technique

[0002] Gas-liquid separation technology is an important technology for separating and removing liquid droplets and mist droplets dispersed in air flow in industrial production. In unit operations such as absorption, rectification, desorption, etc., when the gas leaves the plate tower, packed tower or spray tower, it carries a certain number of liquid droplets or mist droplets of different sizes. For example, carbon capture and storage technology is a technology with large-scale carbon dioxide emission reduction potential. Among them, the chemical absorption method of post-combustion carbon capture is through the chemical reaction of flue gas and chemical solvent in the absorption tower...

Examples

Embodiment 1

[0055] Figure 14 Shown is a comparison chart of the acid mist treatment effect of the device of the present invention.

[0056] Taking acid mist treatment as an example, hydrochloric acid is commonly used as a pH adjuster in mineral processing plants. When in use, a large amount of acid mist will be generated in the mixing tank. The particle size of the acid mist is 0.1-10 μm. The acid mist discharge is harmful to the health of operators. Corrosion plant equipment.

[0057] The baffle type demister, the cylinder type cyclone demister and the aerosol collection and separation device of the present invention are respectively used for treatment. After treatment, the separation efficiency of the baffle plate type mist eliminator is 50%, the separation efficiency of the cylindrical cyclone type mist eliminator is 75%, and the separation efficiency of the spiral folded plate of the present invention reaches 99%.

[0058] The invention has the characteristics of fast separation sp...
