Graphite reaction kettle for hydrogen chloride production

Abstract

The present invention provides a graphite reaction kettle for hydrogen chloride production, which comprises: a base assembly, which comprises a heat transfer type graphite reaction cylinder and an exhaust port; the mixing assembly comprises a supporting seat fixedly embedded in the top of the cover plate, a hollow shaft movably penetrates through the middle of the supporting seat up and down, a spiral blade is arranged at the position, below the base plate, of the outer wall of the hollow shaft, and a plurality of sets of seepage holes are formed in the position, below the base plate, of the circumferential outer wall of the hollow shaft at equal intervals from top to bottom; and the air inlet assembly comprises an air inlet assembly which is arranged at the top of the supporting seat through a bracket. The mixing assembly is arranged, the hollow shaft rotates through the driving device and the gear set, then materials circularly flow from bottom to top through the spiral blades, hydrogen chloride gas seeps out of the seepage holes, the materials and the hydrogen chloride gas are evenly mixed, and the reaction quality is improved.

Description

technical field [0001] The invention belongs to the field of graphite reactors, in particular to a graphite reactor for hydrogen chloride production. Background technique [0002] In chemical production, some materials need to pass hydrogen chloride into the reaction kettle to participate in the synthesis when reacting in the graphite reactor. [0003] The principle of an existing graphite reactor for hydrogen chloride production in the prior art is: the existing hydrogen chloride gas is passed into the reactor through a pipeline and has poor mixing uniformity with the internal material, and the material at the bottom cannot be mixed with the hydrogen chloride gas. Most of the hydrogen chloride gas introduced is at low temperature or normal temperature, which will cause the material temperature in the reactor to decrease compared with before, resulting in energy waste. Contents of the invention [0004] In view of the above-mentioned defects or deficiencies in the prior a...
