Special forced turbulence double-acting reactor for molybdenum disulfide production

Abstract

The invention relates to a special forced turbulence double-acting reactor for molybdenum disulfide production. The special forced turbulence double-acting reactor is characterized by comprising a reactor barrel, a reactor jacket sleeving outside the reactor barrel, a motor mounted at the top of the reactor barrel, and an emulsifying unit hoisted in the reactor barrel and driven by the motor, theemulsifying unit is composed of two one-way emulsifying machines which are arranged in a multi-hole box body in a symmetrical combination mode and are of the same structure. Solid-liquid reaction materials are sucked into the inner cavity from the upper direction and the lower direction of the emulsifying unit; the slurry is dispersed in the super gravity field formed by the high-speed rotation ofthe emulsifying machines, collides, rubs and shears between a stator and a rotor, and is ejected from the circumferential direction of the emulsifying unit. The flow direction is changed by the liquid resistance and the collision of the reactor wall to form turbulence, the solid-liquid mixing reaction process is strengthened, the solid particle size distribution is refined, the double effects ofstrengthening solid-liquid reaction and particle crushing are realized, the reaction time is shortened, and the product quality is improved.

Description

technical field [0001] The invention relates to a special forced turbulent double-action reactor for the production of molybdenum disulfide, which belongs to the field of chemical engineering. Background technique [0002] Molybdenum disulfide is a black powder with metallic luster, which belongs to the hexagonal crystal system. It has the properties of diamagnetism and semiconductor. Among them, Mo-S has many facets, large specific surface area, covalent bonds in the layer, and layer to layer. Between the van der Waals force, the layers are easily separated, showing a very low coefficient of friction. And because sulfur has a strong adhesion ability to metal, it can make molybdenum disulfide adhere to the metal surface well, and always play a lubricating function, especially under the conditions of high temperature and high vacuum, it still has a low friction coefficient. Due to its special properties, it can be widely used as a good solid lubricant in the solid lubricant ...

AI Technical Summary

Problems solved by technology

But the current process has the following problems: 1. The enamel reactor is a frame-type agitator, and the materials are mixed in a laminar flow along the circumferential rotation, which is easy to cause the molybdenum concentrate to agglomerate and sink (large particles) and float (fine particles), and the dispersion is uneven. , the reaction time is long and the reaction is not complete; 2. The core impurities of the large particles of molybdenum concentrate cannot be effectively removed, which seriously affects the product quality
