Technical Field
[0001] The utility model relates to the technical field of disproportionation reactors, in particular to a disproportionation reactor. Background Art
[0002] Disproportionation reactor is a device for disproportionation reaction. The pressurized hydrogen gas phase disproportionation method uses an adiabatic fixed bed reactor, which is a radial flow reactor. It has the following advantages: (1) small bed pressure drop; (2) can reduce secondary reactions and improve reaction selectivity. The atmospheric pressure gas phase disproportionation method uses a mobile reactor. The advantages are mild operating conditions, can be carried out at atmospheric pressure, and no hydrogen is used, which can save the hydrogen compressor. However, the catalyst is frequently regenerated due to burning, and the operation is more complicated than the fixed bed. The low temperature liquid phase disproportionation method uses a fixed bed reactor.
[0003] At present, when preparing sodium sulfide and sodium sulfite in the kettle of the disproportionation reactor, sulfur and alkaline raw materials are placed in a reactor for disproportionation reaction, and then the compound raw materials in the kettle are heated to reach the temperature of the disproportionation reaction for disproportionation reaction. When the disproportionation reaction is heated in the disproportionation reactor, the stirring rod of the reactor is usually used with a stirring structure to assist the stirring of the sulfur and alkaline raw materials during the disproportionation reaction. The common stirring rod bodies of the disproportionation reactor are mostly straight-plate stirring structures. This simple stirring structure has low stirring assistance efficiency for the disproportionation reactants, thereby affecting the contact and heating reaction efficiency of the disproportionation reactants. For this reason, we propose a disproportionation reactor. Utility Model Content
