The invention provides an efficient collection device for secondary zinc oxide, and relates to the technical field of secondary zinc oxide collection. The efficient collection device for secondary zinc oxide comprises a smoke inlet pipe and a filter box, one end of the smoke inlet pipe fixedly communicates with the upper portion of the filter box, a sealing cover is connected to the upper portionof the filter box in a sealed mode, a filter connecting plate is fixedly connected to the upper portion of the interior of the filter box, and three filter screens are fixedly connected to the bottomof the filter connecting plate at equal intervals; three ash falling hoppers are arranged at the bottom of the filter box, the ends, away from the filter box, of the three ash falling hoppers fixedlycommunicate with a first collecting box, the end, away from the smoke inlet pipe, of the filter box fixedly communicates with a communicating pipe, and the end, away from the filter box, of the communicating pipe is fixedly connected with an electrostatic ash collecting box. According to the electrostatic dust collection box, ultrafine smoke dust which cannot be filtered by the filter screen can be collected through the electrostatic effect, an ultra-dense filter screen does not need to be arranged, the gas flow speed can be increased, and the collection efficiency of the device is greatly improved.
Description
technical field [0001] The invention relates to the technical field of secondary zinc oxide collection, in particular to a high-efficiency collection device for secondary zinc oxide. Background technique [0002] Most of the lead-zinc mineral raw materials are symbiotic lead-zinc ores, and it is difficult to achieve complete separation of lead and zinc through preferential flotation. Lead-zinc ore smelting is to enrich zinc in slag, and then process the slag with a fuming furnace to produce zinc oxide or sub-zinc oxide. In addition, the leaching slag and lean zinc oxide ore produced by the wet zinc smelting plant are fumed in a rotary kiln to obtain zinc oxide or sub-zinc oxide. The main component of secondary zinc oxide is ZnO, but the grade is generally 45% to 65%. The so-called "secondary" refers to the grade. In my country's Guangxi, Guizhou, Yunnan, Hunan and other places, the output is relatively large, and its main use is to further process electrolytic zinc or zinc...
