Air separator shell structure

Abstract

The invention discloses an air separator shell structure. The air separator shell structure comprises an axial flow machine shell, a centrifuge shell and a conical end plate; the centrifuge shell is provided with a centrifugal end upper shell and a centrifugal end lower shell; the axial flow machine shell is provided with an axial flow end upper shell and an axial flow end lower shell; a first connecting end is arranged on the axial flow machine shell at one end of the axial flow end upper shell, and is fixedly connected with the centrifuge shell at one end of the centrifugal end upper shell;and a second connecting end is arranged on the axial flow machine shell at one end of the axial flow end lower shell, and is fixedly connected with the centrifuge shell at one end of the centrifugal end lower shell. The air separator shell structure is provided with the axial flow machine shell, the centrifuge shell and the conical end plate; the centrifuge shell is provided with the centrifugal end upper shell and the centrifugal end lower shell; and the centrifugal end upper shell and the centrifugal end lower shell are fixedly connected through a split flange, so that the device is conveniently fixed and dismounted, the maximal weight of lifted parts in factories and user scenes is conveniently reduced, and the factory building construction cost is conveniently reduced.

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. When used in factories and user sites, the maximum lifting weight is re...

[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
