Description

Technical Field

[0001] The utility model relates to the technical field of coke oven gas desulfurization devices, in particular to a hydrogenation pre-converter which is convenient for controlling the bed temperature. Background Art

[0002] Hydrogenation pre-converter is generally used in the production of coke oven gas desulfurization. A catalyst is installed inside for desulfurization. The active state of the catalyst is generally a reduced state. The existing hydrogenation reactor is large in size and requires manual tightening of several bolts when connecting the pipeline, which is very troublesome and the workload is quite large, making it difficult to improve work efficiency.

[0003] For example, the publication number CN202022266772.3 discloses a "combined pre-hydrogenation reactor", in which the first handle is pushed to make the circular ring composed of the first semicircular ring frame and the second semicircular ring drive each adjacent transmission gear to start rotating, and then each transmission gear also drives the corresponding positioning nut to rotate in each limit cover, so that the positioning nut is gradually screwed with the fixing bolt, and the fixing bolt is also gradually screwed with the threaded groove on the transmission gear, so as to quickly complete the connection and fixation between the pipeline and the material port of the reactor body, thereby improving the installation efficiency of the connecting pipeline.

[0004] The above device is still fixed with nuts, and the positioning of the pipes at both ends is still relatively troublesome, resulting in a certain amount of time required for pipe alignment. Although the number of nuts is reduced, the assembly and disassembly of the nuts is still relatively cumbersome, and then they cannot be disassembled without a corresponding screwdriver, so it will still affect the efficiency of the pipe connection.
