Description

Technical Field

[0001] The invention belongs to the technical field of absorption towers, and in particular relates to a tower plate support of a methanol water-washing absorption tower and an assembly method thereof. Background Art

[0002] There are a large number of staggered arrays of trays in the absorption tower, which are responsible for storing liquid at a certain height and are used for the exchange of steam and liquid. There is a certain gap between the trays and the tower body, and a downcomer is set in the gap for the liquid to flow down.

[0003] Since there are a large number of tower plates in the absorption tower, even if the tower body is divided into several sub-tower bodies, there are still a large number of tower plates in each sub-tower body, and the tower plate body needs to be fixed to the tower wall, leaving only space for the liquid to flow down. However, since the deviation between the inner diameter specification of the tower plate bracket and the tower body is small (welding connection is required), during the tower manufacturing process, the tower plate bracket will interfere with the tower wall when moved into the tower body, moved within the tower body, and adjusted its position angle within the tower body, which is not conducive to the operation of the staff, thereby affecting work efficiency and may affect the accuracy of the installation position.

[0004] Therefore, designing a tower tray support that is convenient for assembly is a problem that needs to be solved by those skilled in the art. Summary of the invention
