Abstract

The invention provides a treatment device and method for fluorine-containing waste gas and relates to the technical field of waste gas treatment. The treatment device comprises a main trough body and an air inlet pipe mounted at the top of the main trough body, wherein a through hole used for connecting a liquid storage tank is formed in the external side wall of the main trough body, the main trough body comprises a plurality of partition grooves formed through isolation by at least two partition boards, a filler layer is arranged in each partition groove and divides each partition groove into an upper spraying and purifying layer and a lower solution adsorbing layer, and an air vent for introducing the waste gas into another partition groove is formed in each partition board. With the use of the device, the fluorine-containing waste gas is subjected to adsorption and purification treatment through multiple procedures, the purification efficiency of the fluorine-containing waste gas is high, and the treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a treatment device and method for waste gas containing fluorine. Background technique [0002] At present, phosphoric acid and phosphate fertilizer plants, glass production, aluminum alloy production, lithium hexafluorophosphate production, waste lithium-ion battery electrolyte recycling, waste lithium-ion battery recycling and cracking, and lithium-ion battery production all produce a large amount of fluorine-containing waste gas, and the concentration of waste gas high. Fluorine-containing waste gas is extremely harmful to humans, animals and plants, and must be purified to meet the emission standards stipulated by the national environmental protection department before being discharged at high altitudes. [0003] In the prior art, fluorine-containing waste gas generally adopts two-stage absorption, which is divided into one chamber and one device, one chamber and ...
