Abstract
The present invention discloses a straight cylinder-shaped flow baffling demister, which comprises a plurality of demisting assemblies, wherein each demisting assembly comprises a gas rising pipe and a straight cylinder, the straight cylinder is arranged on the outer side of the gas rising pipe and is at the same axis line as the gas rising pipe, the gas rising pipe is fixed on a tower disk, the top portion of the gas rising pipe is provided with a sealing cover plate, the circumference of the gas rising pipe is provided with a plurality of seams, and the gas rising pipe circumference close to each seam is provided with tangential diversion wings. According to the straight cylinder-shaped flow baffling demister, the separation of the liquid droplet and the gas is achieved through the multiple flow baffling during the fluid flowing process; and the straight cylinder-shaped flow baffling demister has characteristics of simple structure, easy installation and effective gas-liquid separation achieving, and is suitable for the gas-liquid separation process in the fields of chemical industry, environmental protection, and the like.
Description
Technical field [0001] The invention relates to a straight cylindrical baffled demister, which belongs to the field of gas-liquid separation in chemical engineering, and is suitable for gas-liquid separation processes in the fields of chemical engineering and environmental protection. Background technique [0002] SO 2 And dust is an important cause of air pollution in our country, and it is also an air pollutant that our country currently focuses on controlling. At present, the wet process is mostly used in the field of environmental protection. In the wet process flue gas desulfurization process, the absorption tower is prone to produce "mist" with a particle size of 10-60 microns during operation, which not only contains water, but also dissolves sulfuric acid , Sulfate, SO 2 And so on, causing pollution to the atmospheric environment, and at the same time causing serious corrosion to the exhaust tube and heat exchanger. Therefore, in the wet desulfurization process, the puri...
