Air Separation Cabinet Structure

Abstract

The invention discloses an air separation casing structure, which comprises an axial flow casing, a centrifuge casing and a conical end plate. The centrifuge casing is provided with a centrifugal end upper casing and a centrifugal end lower casing. The axial flow The casing is provided with an upper casing at the axial flow end and a lower casing at the axial flow end. The axial flow casing at one end of the upper casing at the axial flow end is provided with a first connection end, and the first connection end is connected with the upper casing at the centrifugal end. The centrifuge casing is fixedly connected, and the axial flow casing at one end of the lower casing at the axial flow end is provided with a second connecting end, and the second connecting end is fixedly connected with the centrifuge casing at one end of the lower casing at the centrifugal end. The present invention is equipped with an axial flow casing, a centrifuge casing and a conical end plate. The centrifuge casing is provided with a centrifugal end upper casing and a centrifugal end lower casing. The fixed connection of the mid-section flange facilitates the fixed disassembly and assembly of the device, facilitates the reduction of the maximum lifting weight of the factory and the user's site, and facilitates the reduction of the construction cost of the plant.

Description

technical field [0001] The invention relates to the technical field of air separation equipment, in particular to an air separation casing structure. Background technique [0002] In recent years, with the rapid development of metallurgy, petrochemical, and coal chemical industry, the demand for air separation equipment is increasing, and there is a trend of large-scale development. With the development of air separation technology, it has better economies of scale. Large air separation There are more and more market applications, but the existing main fans of large air separation systems mostly use centrifugal compressors, which gradually show a certain gap in terms of operating efficiency compared with axial flow + centrifugal compressors. [0003] Most of the existing large air separation units are of integral casting structure, which is not convenient for fixed disassembly and assembly of the device.

[0002] In recent years, with the rapid development of metallurgy, petrochemical, and coal chemical industry, the demand for air separation equipment is increasing, and there is a trend of large-scale development. With the development of air separation technology, it has better economies of scale. Large air separation There are more and more market applications, but the existing main fans of large air separation mostly use centrifugal compressors, which gradually show a certain gap in terms of operating efficiency compared with axial flow + centrifugal compressors

[0003] Most of the existing large air separation units are of integral casting structure, which is not convenient for fixed disassembly and assembly of the device. When used in factories and user sites, the maximum lifting weight is relatively large, the construction cost of the plant is high, and the strength and rigidity of the casing are low. The position of the support is unreasonable, and the device is prone to deformation due to the excessive weight of the device itself, which affects the use of the device. At the same time, the existing large air separation body is not convenient for the guidance of the axial flow end, which makes it difficult for the stator to be positioned accurately during installation, thereby damaging the fit. surface, affecting the use of the device
