Connecting structural component for air-separation cold box and method for integrally assembling cold box

Abstract

The invention discloses a connecting structural component of an air-separation cold box, which comprises a conjunct connector capable of being arranged on a joint of an frame steel tube or fractionating tower body consisting of involutory upper and lower parts in the cold box, and is characterized in that: the guide connector consists of at least one section of inner cylinder fixed on the inner wall of the joint end of a steel tube and used for docking guidance, and a cone connected on the inner cylinder. Compared with the prior art, the connecting structural component has the characteristics of having simple structure and convenient use and installation, meeting the quality requirement on integrally assembled cold box on site, preventing the malposition of the fractionating tower body which cannot be corrected artificially, guaranteeing the alignment of the fractionating tower and the proper position of a welding plate, and the like.

Description

technical field [0001] The invention relates to a connection structure specially used for large and medium-sized air separation packaged cold boxes, which is used for accurate alignment of the packaged cold box and the equipment in the cold box when installed on site by users. Background technique [0002] In the prior art, the equipment in the large and medium-sized air separation cold box is generally installed on site. Due to limited site conditions, the installation quality cannot be effectively guaranteed, and the construction period is relatively long. Although the fully assembled air separation plant can solve this contradiction, the fractionation tower of the large and medium-sized air separation plant is tall, and the length of the cold box after assembly is 50-60 meters, which needs to be cut into two or more sections before transportation; however How to ensure the installation quality of the cut-off cold box to the site has become a technical problem that needs t...
