Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen sulfide gas generation, in particular to a hydrogen sulfide gas generation device. Background Art

[0002] The principle of hydrogen sulfide preparation commonly used in laboratories in the chemical industry is to generate hydrogen sulfide gas by reacting ferrous sulfide with hydrochloric acid at room temperature. However, this preparation method generally requires a Kipp generator made of glass, and the Kipp generator has many connection points and is difficult to be completely sealed. Therefore, a certain amount of hydrogen sulfide often leaks out during the generation of hydrogen sulfide. Since hydrogen sulfide is a highly toxic gas, the leaked hydrogen sulfide will not only have a huge impact on the surrounding environment, but also greatly damage the health of the experimental operators. At the same time, since hydrochloric acid is a volatile acid, a certain amount of hydrogen chloride gas is inevitably mixed into the hydrogen sulfide gas prepared by the method of reacting ferrous sulfide with hydrochloric acid, resulting in insufficient purity of the prepared hydrogen sulfide and a large impurity content. In summary, the disadvantages of the existing method for preparing hydrogen sulfide gas are: ① The experimental device is difficult to be completely sealed, resulting in hydrogen sulfide leakage, which affects the surrounding environment and the personal health of the experimenter; ② The prepared hydrogen sulfide gas often contains hydrogen chloride gas, which is not pure enough.
