Embodiment 1

[0028] Example 1 Centrifugal compressor for gasoline hydrogenation upgrading device

[0029] This embodiment 1 is a six-stage centrifugal compressor with six impellers arranged in line. The impeller adopts a binary closed impeller with a diameter of 400 mm. Its blades adopt a backward curved structure; the diffuser adopts a vaneless diffuser. Steam conditions are available according to user site conditions, so this embodiment adopts steam turbine drive.

Embodiment 2

[0030] Example 2 Centrifugal compressor for gasoline hydrogenation upgrading device

[0031] This embodiment 2 is an eight-stage centrifugal compressor with eight impellers in line. The impeller adopts a binary closed impeller with a diameter of 400 mm. Its blades adopt a backward curved structure. The blades of the front and rear impellers deflect 15 degrees; adopt no blades Diffuser. In this embodiment, the user site does not have steam conditions, so the reforming device adopts the form of a motor, a gear box, and a compressor.

Embodiment 3

[0032] Example 3 Centrifugal compressor for diesel hydro-upgrading device

[0033] This embodiment 3 is a seven-stage centrifugal compressor with seven impellers arranged in line. The impeller adopts a binary closed impeller with a diameter of 400 mm. Its blades adopt a backward curved structure; the diffuser adopts a vaneless diffuser. Steam conditions are available according to user site conditions, so this embodiment adopts steam turbine drive.

Abstract

The invention relates to a centrifugal compressor for a gasoline and diesel oil hydrogenating and upgrading device. The centrifugal compressor for the gasoline and diesel oil hydrogenating and upgrading device comprises four parts of a stator group part, a rotor group part, a bearing group part and dry gas seals. The centrifugal compressor for the gasoline and diesel oil hydrogenating and upgrading device is characterized in that (1) a vertical partition structure is adopted in the compressor; (2) partition plates are assembled together to form a partition bundle, and vaneless diffusers are adopted in diffusers between the partition plates and the partition plates; (3) the arrangement form of impellers on a main shaft is in a straight row, the number of the impellers is six to eight, and the diameter is 400mm; (4) between the two adjacent impellers, blades of the latter impeller are arranged to deflect at a certain angle relative to the blades of the previous impeller; (5) a tilting pad bearing is adopted in a supporting bearing adopts; (6) a kingsbury type structure is adopted by a thrust bearing, and a same structure is adopted by the two sides of the thrust bearing; and (7) thedry gas seals are installed at both ends of the compressor, and independent control systems are arranged on the dry gas seals. The centrifugal compressor is particularly suitable for the application of a gasoline and diesel oil hydrogenating and upgrading process.

Description

Technical field [0001] The invention belongs to the technical field of petrochemical industry, and specifically relates to a centrifugal compressor used in a matching device for gasoline and diesel hydrogenation upgrading. Background technique [0002] The construction of hydrogenation equipment and the development of hydrogenation technology in various countries in the world have been significantly accelerated. Hydrogenation technology has become an important development direction of the oil refining industry to meet the requirements of clean fuel production and environmental protection. With the general trend of world crude oil becoming heavier, inferior and clean fuel production requirements, countries around the world generally use hydrogenation technology to upgrade oil products. [0003] The medium-pressure hydro-upgrading process is a new process developed in the mid to late 1980s in response to the needs of catalytic cracking, especially heavy oil catalytic cracking diesel...
