The method of purifying an exhaust gas containing mercury amalgamation of many jobs, is currently the most commonly used chloride - activated carbon adsorption and absorption soft manganese ore and the like. Chlorination-activated carbon adsorption method is to make the mercury ions in the exhaust gas react with chlorine to form precipitated mercurous chloride. Hg+Cl 2 The remaining mercury is then recovered by adsorption of activated carbon. Mercury removal by chlorination-activated carbon adsorption method, the adsorption rate of mercury can reach 99.9%. The pyrolusite absorption method is to wash the mercury-containing waste gas with a dilute sulfuric acid solution containing pyrolusite to form a mercury sulfate recovery. 2Hg+MnO 2 Hg 2 MnO 2 +4H 2 SO 4 +MnO 2 The operation of the pyrolusite absorption method is to introduce mercury vapor or waste gas containing liquid fine mercury beads into a washing tower with bricks, and send a dilute sulfuric acid solution containing finely divided pyrolusite to the tower for scrubbing, mercury and The pyrolusite is absorbed after contact and produces mercuric sulfate. In the circulation the washing liquid column, when the sulfite concentration of mercury in the washing liquid enriched to about 200g / m 3, that is discharged from the tower, with iron chips or substitutions to precipitate copper scrap recovery of mercury. The mercury absorption efficiency of this method can reach 95% to 99%.
Rice Hulling Combination Rice Machine
The combined rice husker has the advantages of low power, low energy consumption, large output, easy operation and good maintenance. The machine consists of a single-link elevator, a multifunctional cleaning and stone removing machine, a new split rice huller ( the core part of the equipment ), a double-link elevator, a grain rough separating screen, a negative pressure rice refining machine, a broken rice separating screen, a multifunctional crusher and a central centralized controller. The fuselage is made of wear-resistant glass pipes, which are durable and beautiful.
