Treatment system for antimony oxide powder in pyrogenic process antimony smelting process

Abstract

The invention discloses a treatment system for antimony oxide powder in the pyrogenic process antimony smelting process. The treatment system comprises a blast furnace, a constant-temperature fire cabinet, an air cooling cylinder and an air cooling tower. The blast furnace is connected with the constant-temperature fire cabinet through a dry gooseneck. The constant-temperature fire cabinet is connected with the air cooling tower through the air cooling cylinder. Vertical partition plates are arranged in the constant-temperature fire cabinet. A through hole is formed in each vertical partition plate. The through holes in the adjacent vertical partition plates are formed in a staggered manner so that a rectangular wave type channel can be formed in the constant-temperature fire cabinet. The end, close to the air cooling tower, of the air cooling cylinder is provided with a sleeve, and the other end of the air cooling cylinder is directly connected with the fire cabinet. A wheel capable of moving is arranged below the air cooling cylinder. A small door is arranged on the side face of the air cooling tower, and the opening and closing degree of the small door is controlled through a controller. According to the treatment system for the antimony oxide powder in the pyrogenic process antimony smelting process, the quality of the antimony oxide powder can be improved, in addition, oxygen combination and generation of red water can be basically avoided as well, and it is ensured that production is conducted smoothly.

Description

technical field [0001] The invention relates to a treatment system for antimony oxide powder in the process of pyrochemical antimony smelting. Background technique [0002] There are currently two types of antimony smelting methods: fire method and wet method. The wet method generally adopts diaphragm electrodeposition, and the product obtained is cathode antimony, with an antimony content of only about 95%, which does not meet the national standard requirements. The fire method is the main method, and the blast furnace is used for more volatilization and smelting in the fire method. Antimony sulfide is volatilized and smelted in the blast furnace to become antimony oxygen powder, which is cooled by the gooseneck and fire cabinet and enters the dust collection system. One problem is that the quality of antimony oxide powder is not high. Because the antimony oxide powder is not fully oxidized, the mass antimony content of the general antimony oxide powder is preferably around...

Problems solved by technology

[0002] There are currently two types of antimony smelting methods: fire method and wet method. The wet method generally adopts diaphragm electrodeposition, and the product obtained is cathode antimony, with an antimony content of only about 95%, which does not meet the national standard requirements. The fire method is the main method, and the blast furnace is used for more volatilization and smelting in the fire method. Antimony sulfide is volatilized and smelted in the blast furnace to become antimony oxygen powder, which is cooled by the gooseneck and fire cabinet and enters the dust collection system. One problem is that the quality of antimony oxide powder is not high. Because the antimony oxide powder is not fully oxidized, the mass antimony content of the general antimony oxide powder is preferably around 75%, which is difficult to continue to increase. The second is that there is more oxygen. , especially in the gooseneck part, after being cooled by the water cooling jacket, it is easy to generate oxygen and red water, which needs to be cleaned frequently, affecting normal production
