Description

Technical Field

[0001] The utility model belongs to the technical field of tower internals, and particularly relates to a tower internals supporting grid fastening device. Background Art

[0002] The support grid is one of the many tower internals. The support grid is an important industrial equipment component, mainly used to support the packing inside the tower to ensure the stability and uniformity of the packing, thereby increasing the contact area of ​​the packing and improving the reaction efficiency. The support grid is widely used in petrochemical, environmental protection and other fields. The diameter of the tower is large. For easy installation, the support grid needs to be designed in blocks. And considering that some tower equipment has backflush conditions during operation, not only do the block grids need to be connected to each other as a whole component, but the grid as a whole also needs to be connected and fastened to the tower equipment. However, it still has the following disadvantages in actual use:

[0003] The installation and fastening of the tower internal support grid usually adopts the method of spot welding bolts on the support ring in advance to fix the grid on the support ring. Due to the heavy weight of a single grid and the small opening of the bolt hole, the operator needs to align it manually. During the alignment process, the manual operation is relatively complicated, so it is very difficult to install on site. The grid often knocks down the bolts and deforms due to collision.

[0004] When disassembling the tower internal support grid, simply unscrew the installation bolts. After unscrewing the bolts, you need to put away the installed bolts to prevent the bolts from falling to the bottom of the tower, causing the bolts to damage the bottom of the tower and affect the integrity of the inner wall of the tower. Utility Model Content
