Description

Technical Field

[0001] The utility model relates to the technical field of methanation reactor equipment, in particular to a plugging device for a methanation reactor. Background Art

[0002] Methanation reactor is an important chemical equipment, mainly used to synthesize methane from carbon monoxide and hydrogen under the action of catalyst. This reactor has a wide range of applications in the fields of chemical industry and energy, and is a key link in realizing coal gasification and conversion of synthesis gas into clean fuel. Methanation reactor usually consists of reaction chamber, catalyst bed, feeding and discharging system, temperature and pressure control system, etc.

[0003] In order to ensure that debris does not enter the tank during transportation and storage, effective sealing measures must be implemented for the air inlet and outlet. The traditional sealing method is to use plastic film to tightly wrap the opening in multiple layers. However, this method is not only cumbersome to operate, resulting in low work efficiency, but also the plastic film itself is easily damaged and cannot guarantee a long-term sealing effect. Therefore, we urgently need to seek a more efficient and reliable sealing solution, such as the Chinese utility model patent disclosed by publication number CN213117457U, a sealing device for a methanation reactor. This application can form a reliable sealing effect on the air inlet and outlet of the methane reactor to prevent dust, rainwater and other impurities from entering. First, in this application, although a part of the weight can be reduced by opening a weight-reducing groove in the blocking column, it is impossible to ensure that the end plate has a good explosion-proof ability. Secondly, in this application, two threaded columns are used to connect with the outlet pipe or the inlet pipe. The two-point fixing method cannot ensure the close connection between the end plate and the end face of the outlet pipe or the inlet pipe. At the same time, if a threaded column is added, the disassembly and assembly of the end plate will become cumbersome. Utility Model Content
