Abstract

The invention discloses a two-stage cavitation bubble generator, comprising: a first cavitation section, which includes a first jet chamber, a compression channel, an air cavity, and a mixing channel; the first jet chamber, a compression channel, an air chamber, The mixing channel communicates in sequence along the fluid flow direction; the second cavitation section, which includes a second jet chamber with an open end, an outlet channel for outputting fluid, and a central body; the open end of the second jet chamber is connected to the fluid in the first cavitation section The output end is connected, and the other end of the second jet chamber communicates with the outlet channel; the wall of the second jet chamber is provided with a low-pressure fluid inlet communicating with it; the center body is arranged in the middle of the second jet chamber and is fixedly connected with it, and the center body The radial center is provided with a center body channel for mixing fluid and gas. The cavitation bubble generator has high cavitation efficiency, and a single generator has a wide range of cavitation effects, which can be effectively used in the dissociation process of high-sulfur slag, improve the separation effect of slag-sulfur, and provide a good solution for subsequent flotation sulfur extraction. Base.

Description

technical field [0001] The invention relates to the field of heavy metal metallurgy, in particular to a two-stage cavitation bubble generator. Background technique [0002] The direct leaching process realizes the full wet treatment of zinc sulfide concentrate. The zinc production capacity of the direct leaching process of zinc concentrate in my country is about 500,000 tons / year, and the total amount of high-sulfur slag produced along with it reaches 600,000 tons / year. In addition to elemental sulfur, high-sulfur slag also contains valuable components such as zinc, lead, silver, indium, and toxic elements such as arsenic, cadmium, and mercury. The efficient recovery of elemental sulfur from acid leaching slag embodies the advantages of direct leaching technology. It is also beneficial to the comprehensive recovery of valuable components in the subsequent acid leaching residue. At present, domestic zinc direct leaching enterprises generally adopt the "flotation-hot filtrati...
