Description

Technical Field

[0001] The utility model relates to the technical field of black powder tail gas treatment, and particularly relates to a black powder tail gas absorption and emission device. Background Technique

[0002] There are many varieties of black powder. Commonly used ones include butylamine black powder, sodium butyl black powder, and No. 25 black powder. Butylammonium black powder can be used as a collector for sulfide ores such as copper, lead, zinc, and nickel, and has certain foaming properties. It has a strong collecting ability for some refractory ores such as molybdenite. It is relatively stable in acidic media. When xanthate is not suitable for use in the medium, black powder can be used instead. During the production process of black powder, by-products such as H2S gas and volatile substances of raw materials such as NH3 and C7H8O are generated, seriously polluting the environment. Therefore, it is necessary to absorb the gas before discharging it.

[0003] The black powder tail gas is injected into the liquid medicine in the absorption tank through the inlet pipe. However, the tail gas discharged into the liquid medicine by the inlet pipe cannot fully contact the liquid medicine, and crystals are likely to form at the position of the air outlet holes of the inlet pipe. These crystals cannot be conveniently removed, which will affect the air outlet of the inlet pipe. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a black powder tail gas absorption and emission device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
