Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desulfurization demisters, in particular to a flue gas desulfurization demister for an aluminum electrolysis workshop. Background Art
[0002] The demister is mainly composed of corrugated blades, plates, strips and other fixing devices. When the gas carrying mist rises through the wire mesh at a certain speed, the mist collides with the wire mesh filaments and is attached to the surface of the filaments due to the inertia of the rising mist. When the gathered droplets are large enough that the gravity generated by themselves exceeds the combined force of the rising force of the gas and the surface tension of the liquid, the droplets separate from the filaments and fall.
[0003] Since the emitted "fog" contains not only water, but also sulfuric acid, sulfates and sulfur dioxide, it will cause serious corrosion to the flue when it comes into contact with the inside of the demister. In addition, during the desulfurization process, some incompletely reacted absorbent will remain inside the absorption tower and adhere to the surface of the demister blades, causing the demister to become clogged. In order to alleviate the blockage, the corrugated blades generally have only one bend, but mist is prone to missing mist foam when passing through the corrugated blades with one bend. Utility Model Content
[0004] The utility model aims to provide a flue gas desulfurization demister for an aluminum electrolysis workshop to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flue gas desulfurization demister for an aluminum electrolysis workshop, comprising a protective shell, a plurality of corrugated blades are installed in an internal array of the protective shell, a mounting shell is installed at an opening at one end of the protective shell, a plurality of vertical plates are installed in an internal array of the mounting shell, the plurality of vertical plates and the plurality of corrugated blades are in the same position, two arc-shaped protrusions are staggeredly installed at both left and right ends of the vertical plates, and a multi-section curved air duct is formed between two adjacent vertical plates.

A mounting shell is arranged in the front part of the protective shell. A plurality of vertical plates and arc-shaped protrusions are arranged inside the mounting shell.
