Abstract

The invention discloses a secondary flue gas purification system for an electrolytic aluminum workshop. The invention particularly relates to the field of secondary flue gas purification of electrolytic aluminum workshops. The flue gas purification system comprises a gas collection mechanism and a purification mechanism, wherein the gas collecting mechanism is arranged outside the purifying mechanism; the gas collection mechanism comprises a mounting frame, a connecting plate and a gas collection box, the connecting plate is movably arranged at the bottom of the mounting frame, the gas collection box is detachably arranged at the bottom of the connecting plate, the purification mechanism comprises a purification box, an adsorption chamber, a dust removal chamber and a flushing chamber arearranged in the purification box, and the dust removal chamber is located between the adsorption chamber and the flushing chamber in the vertical direction. According to the invention, secondary fluegas in the electrolysis plant is collected through the gas collecting mechanism, and then is transferred to the purification mechanism for purification treatment; therefore, the secondary flue gas canbe sequentially subjected to adsorption, dust removal and water washing treatment; the treatment effect is better, the treatment efficiency is higher, harmful impurities in the secondary flue gas areeffectively reduced, and discharged gas is more environmentally friendly.

Description

technical field [0001] The invention relates to the field of secondary flue gas purification in an electrolytic aluminum workshop, and more specifically, the invention relates to a secondary flue gas purification system in an electrolytic aluminum workshop. Background technique [0002] The flue gas emitted by the aluminum electrolytic cell is called the primary flue gas collected by the gas collecting hood on the tank, and the flue gas that directly enters the air of the electrolysis plant without being collected by the gas collecting hood is called the secondary flue gas. The volume of the primary flue gas is small, and the fluoride concentration is relatively large, and the volume of the secondary flue gas is relatively large, and the fluoride concentration is relatively small. [0003] The existing secondary flue gas purification system cannot sequentially perform adsorption, dust removal and water washing treatment on the secondary flue gas. Contents of the invention ...
