Technical Field

[0001] The utility model relates to the field of isobutylene production, in particular to a high-efficiency reaction device for producing isobutylene. Background Art

[0002] The main effects of isobutylene are asphyxiation, weak anesthesia and weak stimulation. When mixed with air, it can form an explosive mixture. It is dangerous to burn and explode when encountering heat sources and open flames. It may undergo violent polymerization reactions when heated. It reacts violently when in contact with oxidants. The gas is heavier than air and can diffuse to a considerable distance at a lower level. It will catch fire and burn back when encountering a fire source. At present, isobutylene can be produced by the thermal cracking reaction of methyl tert-butyl ether, and the temperature has a greater influence on the thermal cracking reaction of methyl tert-butyl ether. Generally, methyl tert-butyl ether enters the reactor. Due to the low temperature inside the reactor, it is mostly continuously heated from a low temperature state, which will take up more processing time and thus increase the production cycle of isobutylene. Therefore, it is necessary to provide a new high-efficiency reaction device for producing isobutylene to solve the above technical problems. Utility Model Content
