| titleOfInvention | Method of cleaning gases from dust |
| abstract | The invention relates to a technology for the purification of gases from dust used in the production of mineral fertilizers and allowing a reduction in the residual concentration of dust. Dusty gas is treated in the Venturi tube with irrigation with circulating water with the addition of pulverized CAF 2 and water-soluble polyelectrolyte of the cationic type VPK-402 based on polydimethyldiallylammonium chloride to concentrations (0.5-1) . 10 -3 and (1-2) . 10 -4 wt.%. The particle size of CAF 2 is 0.2-0.3 microns. In the best option, CAF 2 is introduced in the form of a cake for filtering wastewater from the production of semiconductors, rare metals and mineral fertilizers after purification of fluoride ions with lime. The method allows to reduce the residual concentration of dust in the gas to 0.05-0.12 g / cm 3 . 1 tab. |
