Assembly method of internal part of large adsorber

Abstract

The invention discloses an assembly method of an internal part of a large adsorber. The assembly method comprises the following steps that a screen cylinder and a cylinder body are horizontally arranged and aligned correspondingly; an axial guide rail is arranged in the cylinder body; a left lifting beam and a right lifting beam are connected to the two ends of the screen cylinder correspondingly;the screen cylinder is lifted in place through a workshop crane, and a roller device is detachably connected to the bottom end of the right part of the screen cylinder; the screen cylinder is drivento move towards the interior of the cylinder body, and the roller device at the bottom end of the screen cylinder is enabled to roll along the axial guide rail; the screen cylinder is driven to move again until the right lifting beam extends out of a ring plate at the right end of the cylinder body; the extending end of the ring plate of the right lifting beam is hanged by utilizing the workshop crane, and then the roller device and the axial guide rail are disassembled and taken out; and the screen cylinder is driven to move, assembling and welding are carried out after the screen cylinder isin place, then the left lifting beam and the right lifting beam are disassembled, and the assembly of the screen cylinder and the cylinder body is completed. By adopting the assembly method of the internal part of the large adsorber, a long lifting beam does not required to be adopted, so that the span of the largest assembly length is reduced, and the site space requirement is lowered; and materials are saved, cost is reduced, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a method for assembling the inner part of a large adsorber. Background technique [0002] A large adsorber with an internal sieve cylinder. The height of the outer circle of the sieve cylinder is about 14 meters, the height of the head is also 1-2 meters, and the diameter of the sieve cylinder is 7-8 meters. The sieve cylinder needs to be installed in a suitable Inside the cylinder (height 14 meters). Due to the high vertical installation height of the equipment, the height of the workshop crane cannot be satisfied, so it is changed to a horizontal installation form. [0003] see Figure 1-4 , the existing horizontal installation method is: place the screen cylinder 1 and the cylinder body 2 horizontally respectively, and align the screen cylinder 1 with the cylinder body 2 to make tooling (left and right lifting beams), and the length of the left lifting beam 3 is relatively long. Small, detachable connection with the head e...
