Abstract

The invention discloses an efficient demister. The demister comprises a plurality of demisting assemblies, wherein each demisting assembly comprises a riser and an outer cylinder, the outer cylinder is arranged on the outer side of the riser and located in the same axis with the riser, the riser is axially divided into an upper part and a lower part, the upper part is a riser I, the lower part isa riser II, the riser I and the riser II are connected through a bearing, the riser II is fixed on a tray, and rectifying channels are arranged on the circumference of the riser I. The demister can realize separation of drops from gas through rectification, acceleration and scraping effects of a fluid during flowing. The demister is simple in structure, convenient to mount, not prone to scaling and capable of effectively realizing gas-liquid separation and reducing entrainment.

Description

technical field

[0001] The invention relates to a gas-liquid separation device, in particular to a high-efficiency demister. Background technique

[0002] A large amount of SO is produced in the production process of electric power, metallurgy, petrochemical and other industries 2 Harmful substances such as dust and dust have brought serious acid rain hazards and smog weather, and are currently the key air pollutants controlled in our country. At present, the wet desulfurization process is widely used in the field of environmental protection to remove sulfur dioxide and other harmful substances in the flue gas, that is, to spray lye on the flue gas to absorb or adsorb these harmful substances. However, in the wet desulfurization process, the flue gas after desulfurization in the absorption tower contains a large number of fine droplets with a particle size of about 10-60 microns, and sulfuric acid, sulfate, SO 2 etc., will not only pollute the atmospheric environment, but ...

Examples

Embodiment 1

[0053] A wet scrubber purifies flue gas 150000Nm 3 / h, wherein the apparent water concentration is 10-15g / Nm 3 , after demisting by the present invention, the apparent water concentration in the exhaust gas is less than 0.5g / Nm 3 , Demist efficiency ≥ 95%.

Embodiment 2

[0055] A wet scrubber purifies flue gas 100000Nm 3 / h, where the apparent water concentration is 12-16g / Nm 3 , after demisting by the present invention, the apparent water concentration in the exhaust gas is less than 0.6g / Nm 3 , Demist efficiency ≥ 95%.
