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 and treatment system, which belongs to the field of industrial waste gas recovery. A fluorite powder recycling and processing system, including a central control system for flue gas emission of fluorite powder, the central control system for flue gas emission of fluorite powder includes a flue gas extraction module, a recovery processing module, and a flue gas discharge module; the flue gas extraction module, the recycling processing module and The flue gas emission module is connected in sequence; it can adjust the extraction rate of the flue gas in real time by monitoring the state of the flue gas when extracting the flue gas, avoiding excessive fluorite powder being extracted during the combustion process, and passing through the flue gas pretreatment device Pre-separate and stratify the fluorite powder particles in the exhausted state, so that when the fluorite powder particles in the smoke pass through the water spray module, the water mist can concentrate on the large particles Flush, to increase the likelihood of Glowstone Dust being left behind.
Description
technical field [0001] The invention relates to the field of industrial waste gas recovery, and more particularly, to a fluorite powder recovery and treatment system. Background technique [0002] Fluorite powder, also known as fluorite, fluorspar, fluorspar powder. It is a mineral, equiaxed crystal system, the main component of which is calcium fluoride. An important use of fluorite is in the production of hydrofluoric acid. Hydrofluoric acid is produced by the reaction of acid grade fluorite (fluorspar concentrate) with sulfuric acid in a heating furnace or tank. It is divided into anhydrous hydrofluoric acid and anhydrous hydrofluoric acid, both of which are colorless liquids. , volatile, has a strong irritating odor and strong corrosiveness. It is a key raw material for the production of various organic and inorganic fluorides and fluorine elements. [0003] In the production process, the "flue gas" (air flow) discharged from the burner still contains a large amount ...
