Problems solved by technology
However, when spraying with water, due to the different sizes of fluorite powder particles and the rate of smoke emission, and the fact that the water mist cannot fully contact the fluorite powder during water spraying, it cannot be guaranteed that most of the fluorite powder particles will be left by the water. There will still be a lot of fluorite powder that will be discharged with the smoke directly without contact with the water mist, and when the smoke is drawn out, the smoke will leave some fluorite powder particles on the wall of the smoke pipe under the impact of the air flow , resulting in too much fluorite powder attached to the pipe wall, affecting the recovery of fluorite powder

The invention discloses a fluorite powder recovery treatment system, and belongs to the field of industrial waste gas recovery. The fluorite powder recovery treatment system comprises a fluorite powder flue gas emission central control system, and the fluorite powder flue gas emission central control system comprises a flue gas extraction module, a recovery treatment module and a flue gas emission module; the flue gas extraction module, the recovery treatment module and the flue gas emission module are connected in sequence; the flue gas extraction rate can be adjusted in real time by monitoring the flue gas state when flue gas is extracted, excessive fluorite powder is prevented from being extracted in the combustion process, and the flue gas in the extracted state is subjected to pre-separation and layering of fluorite powder particles with different sizes through the flue gas pretreatment device; therefore, when fluorite powder particles in the flue gas pass through the water spraying module, water mist can intensively scour large particle parts in a concentrated manner, so that the possibility that the fluorite powder is left is increased.
Description
Technical field [0001] The present invention relates to the field of industrial waste gas recovery, and more particularly to a fluorite powder recovery processing system. Background technique [0002] Fluorite powder, also known as fluorite, fluorine, fluorine powder. It is a mineral, an equipotential crystal system, and its main component is calcium fluoride. An important use of fluorite is to produce hydrofluoric acid. Hyflic acid is produced by reacting with sulfuric acid in a heating furnace or a tank with sulfuric acid, with hydrofluoric acid and hydrofluoric acid, which is a colorless liquid. , Volatile, strong stimulating scent and strong corrosion. It is a key raw material that produces various organic and inorganic fluorides and fluorine elements. [0003] In the production process, in the "smoke" (airflow) of the burner, there will still contain a large amount of fluorite powder, the flue gas needs to be treated, and the fluorite powder is recovered, and the fluorite po...
