Description

Support ring calibration auxiliary tool and support ring installation method

technical field

Tower equipment usually refers to a container with a certain shape (mostly circular in cross section), a certain volume, and certain accessories for internal and external devices. It is one of the important equipment in the production of petroleum, chemical, pharmaceutical, light industry, etc. Full contact between gas-liquid or liquid-liquid two phases is carried out, and mass transfer between phases is carried out. Therefore, in the production process, tower equipment is commonly used to carry out unit operations such as rectification, absorption, desorption, gas humidification and cooling. During the assembly process of the tower equipment, for the placement of its internal tower parts, it is usually necessary to set a support ring inside the tower equipment in advance to provide a focus point for each tower part. Therefore, the levelness of the support ring is related to the overall assembly accuracy, and also Determines the effect of later use.

In the prior art, the support ring is usually installed by welding, that is, the outer diameter edge of the support ring is welded to the inner wall of the tower equipment, and the inner diameter edge extends horizontally to the inside of the tower equipment.
