Description

Technical Field

[0001] The invention belongs to the field of graphite reactors, and in particular relates to a graphite reactor for producing hydrogen chloride. Background Art

[0002] In chemical production, some materials need to be reacted in a graphite reactor by introducing hydrogen chloride into the reactor to participate in the synthesis.

[0003] The principle of a graphite reactor for hydrogen chloride production in the prior art is that the existing hydrogen chloride gas is introduced into the reactor through a pipeline, and the mixing uniformity with the materials inside is poor, and the materials at the bottom cannot be mixed with the hydrogen chloride gas. At the same time, the introduced hydrogen chloride gas is mostly at low temperature or room temperature, which will cause the temperature of the materials in the reactor to be lower than before, resulting in energy waste. Summary of the invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present invention aims to provide a graphite reactor for producing hydrogen chloride.

[0005] In order to solve the above technical problems, the present invention provides a graphite reactor for hydrogen chloride production, which is characterized by comprising a basic component, a mixing component and an air intake component; the basic component comprises a heat transfer graphite reaction cylinder, the left and right sides of the heat transfer graphite reaction cylinder are both provided with exhaust ports, and the top of the heat transfer graphite reaction cylinder is provided with a cover plate; the mixing component comprises a support seat fixedly embedded in the top of the cover plate, a hollow shaft is movably penetrated in the middle of the support seat, and the bottom of the hollow shaft movably penetrates the cover plate and extends to the heat transfer The bottom of the inner cavity of the graphite reaction cylinder is provided with partitions on the left and right sides of the bottom of the cover plate, which are located on the left and right sides of the hollow shaft, a pad is provided on the top between the two groups of partitions, and the pad is movably sleeved on the outer wall of the hollow shaft, and a spiral blade is provided on the outer wall of the hollow shaft below the pad, and a plurality of groups of seepage holes are equidistantly provided on the circumferential outer wall of the hollow shaft below the pad from top to bottom, and a reflux port is provided on the position of the partition at the bottom of the pad, and a driving device is provided on the top of the support seat, and the driving device and the hollow shaft are connected through a gear set.

[0006] The air intake assembly is arranged on the top of the support seat, the top of the hollow shaft is communicated with the bottom of the air intake assembly, and a bearing is arranged at the connection between the hollow shaft and the air intake assembly.

[0007] Beneficial effects:

[0008] 1) The present invention is provided with a mixing component. The driving device and the gear set cause the hollow shaft to rotate, and then the spiral blade causes the material to circulate from bottom to top, and the hydrogen chloride gas seeps out from the seepage holes, so that the material and the hydrogen chloride gas are uniformly mixed, improving the reaction quality. At the same time, the rotation of the hollow shaft causes the two stirring rods to rotate through the sprocket drive set. When the stirring rods rotate, the movable disk drives the U-shaped mixing rod to rotate. At the same time, the contact rod, the arc-shaped convex part and the spring cooperate to make the U-shaped mixing rod move up and down reciprocally during rotation, further improving the mixing quality of the material and the hydrogen chloride gas.

[0009] 2) The present invention is also provided with an air inlet component. The hot air and flue gas discharged when the heat transfer type graphite reaction cylinder is heated enter the air inlet shell, and are discharged after absorbing heat through the honeycomb heat storage block, so that the hydrogen chloride gas is preheated by passing through the honeycomb heat storage block before entering the hollow shaft, playing a preheating role, reducing the heat loss in the reaction kettle, thus saving energy and ensuring that the material reaction is not affected by temperature changes.
