Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a leakage-proof alkylation reactor. Background Art

[0002] Alkylation reaction is a very important component of petrochemical industry. In the standard oil refining process, it can be used to combine low molecular weight olefins with isobutane to form alkylates for gasoline anti-knock; in the petroleum refining process, it can be used to convert gaseous small molecule hydrocarbons produced by cracking into hydrocarbons that can be used for gasoline. In common alkylation reactors, it is usually necessary to set up a circulating impeller to circulate materials, maintain the reaction temperature conditions with the cooperation of the tube heat dissipation device, promote material mixing and improve reaction efficiency. The drive of the circulating impeller requires the use of a transmission shaft from outside the reactor into the reactor, which involves dynamic sealing problems. Therefore, the corresponding equipment maintenance cost is high and it is easy to leak and pollute the environment.

[0004] However, the above technical solution and the prior art still have the following defects: the device uses a traditional single flange to connect and fix the reactor. However, during the operation of the alkylation reactor, the pressure changes inside the reactor will affect the stress of the bolt connection on the flange, causing the flange connection to loosen, thereby affecting the sealing performance and causing possible leakage.
