Treatment device suitable for sodium hydrosulfide

Abstract

The invention relates to the technical field of general chemical experiments, and discloses a treatment device suitable for sodium hydrosulfide, which comprises a reaction box, a rotary airflow mechanism detachably connected in the reaction box, a reactant titration box detachably connected with the reaction box, and a controllable hydrogen sulfide gas generator connected with the rotary airflow mechanism, the rotating airflow mechanism comprises a communicating pipe, a pressure pump connected with the communicating pipe and a rotating disc arranged at one end of the communicating pipe, a plurality of channels communicated with the communicating pipe are formed in the rotating disc, and the rotating disc extends into the bottom of the reaction box and is rotationally connected with the bottom of the reaction box; the reactant titration box comprises a cover plate clamped with the reaction box, a titration box body arranged on the cover plate, a plurality of burettes arranged between the cover plate and the titration box body and a feeding pipe mounted on the titration box body, and the free end of the communicating pipe penetrates through the cover plate and the titration box body to be communicated with the controllable hydrogen sulfide gas generator; the device solves the problems of insufficient reaction, too high residual hydrogen sulfide gas and threat to human health during preparation of sodium hydrosulfide.

Description

technical field [0001] The application relates to the technical field of general chemical experiments, and specifically discloses a processing device adapted to use sodium hydrosulfide. Background technique [0002] Sodium hydrosulfide is a white to colorless cubic crystal with hydrogen sulfide odor; the industrial product is generally a solution, which is orange or yellow. Easy to deliquescence. It decomposes at melting point to release hydrogen sulfide. Soluble in water and alcohol, suitable for various industries, such as: dye industry for the synthesis of organic intermediates and auxiliary agents for the preparation of sulfur dyes; leather industry for depilation and tanning of raw hides; chemical fertilizer industry for desulfurization of activated carbon It is widely used in copper ore beneficiation in mining industry; it is used in sulfurous acid dyeing in man-made fiber production, it is the raw material for the manufacture of ammonium sulfide and pesticide ethane...
