Embodiment Construction

[0029] according to figure 1 and figure 2 As shown, the driving motor 1 installed on the base 0 is connected to the main compressor 3 through the speed increaser 2. The main compressor is provided with an exhaust chamber 4 and an air intake chamber 5. The exhaust chamber is divided into a section of exhaust chamber 4.1 and the second-stage exhaust chamber 4.2, the air intake chamber is divided into a first-stage air intake chamber 5.1 and a second-stage air intake chamber 5.2;

[0030] according to image 3 As shown, the compressor main shaft 14 is installed between two radial bearings 25, a thrust bearing 27 is installed on the outer side of one radial bearing, and the compressor main shaft in the cylinder body 26 is installed in sequence from right to left There are dry gas seals 15, shaft end seals 16, four-stage impellers 17 and five-stage impellers 18, which constitute the second stage, and an outlet volute 19 is provided on one side of the fifth-stage impeller, and th...

Abstract

The invention provides a centrifugal hydrogen sulfide compressor which is formed by a first section and a second section in a compressed mode. The first section is composed of a first-level vane wheel, a second-level wheel and a third-level vane wheel, the second section is composed of a fourth-level vane wheel and a fifth-level vane wheel. A between-section seal is arranged between the first section and the second section. An air inlet chamber and an air exhaust chamber are respectively arranged on the first section and the second section. Due to the fact that the centrifugal hydrogen sulfide compressor continuously adds pressure through two sections of fifth-level vane wheels, and therefore compression ratio is high. Through the selection and arrangement of a sealing part, gas leakage is avoided, efficiency is improved, and the centrifugal hydrogen sulfide compressor is suitable for being used as a compressor in hydrogen sulfide compression pressure addition.

Description

technical field [0001] The invention proposes a core chemical mechanical equipment on a methionine production line, specifically a centrifugal hydrogen sulfide compressor. Background technique [0002] Methionine, also known as methionine, is an important amino acid species. In recent years, the demand for methionine in domestic and foreign markets has increased year by year. Especially in the domestic market, for many years domestic feed methionine is far from meeting the market demand, and it has to be imported in large quantities from abroad every year. Now it has become a major product of chemical raw materials imported in my country. The annual import volume is as high as 200,000 tons, and the import value exceeds 1 billion. Dollar. It is expected that the demand for methionine in the domestic market will increase at a relatively large rate in the future, and the contradiction between supply and demand in the domestic market will not be resolved in the short term, and ...
