Problems solved by technology

At present, except for a small number of industrial application industries that use waste heat for heating, drying gas usually needs to be heated by a stove or an electric furnace, and the blower maintains the flow. The investment in equipment and energy costs is relatively high, and the dry gas after absorbing moisture still has a relatively high temperature. This part of energy It is discharged into the atmosphere without full utilization, resulting in waste of energy. The dried gas also contains a large amount of water, which will produce obvious white smoke when discharged, and at the same time form aerosol with the entrained product particles, which is an important source of smog formation.

Abstract

The invention discloses a coaxial integrated radial-axial mixed-flow wet air turbine compressor rotor structure, which comprises a rotating shaft, and a first journal integrally formed with the rotating shaft, a second-stage gas compressor impeller, a first-stage gas compressor impeller, a turbine rotor wheel disc, a second journal, a thrust disc and a coupler wheel disc sequentially arranged fromleft to right, wherein turbine moving blades are arranged on the turbine rotor wheel disc, and the second-stage gas compressor impeller and the first-stage gas compressor impeller are arranged in a back-to-back mode. The coaxial integrated radial-axial mixed-flow wet air turbine compressor rotor structure has the beneficial effects that according to the scheme, the second-stage gas compressor impeller and the first-stage gas compressor impeller are arranged back to back; meanwhile, a balance hole is formed in the turbine rotor wheel disc, so that the thrust of the whole rotor in the axial direction can be balanced, the situation that the rotor bears large thrust and collides with a bearing is avoided, the shape precision of the rotor is protected against damage, and therefore the effectsof prolonging the service life of the rotor and avoiding vibration noise are achieved.

Description

technical field [0001] The invention relates to the technical field of turbine compressors, in particular to a rotor structure of a coaxial integrated radial shaft mixed flow wet air turbine compressor. Background technique [0002] In order to obtain powdered products in industrial drying process, it is necessary to spray dry the product solution, and use hot air or other gases at a suitable temperature to pass through the liquid droplets and take away moisture. At present, except for a small number of industrial application industries that use waste heat for heating, drying gas usually needs to be heated by a stove or an electric furnace, and the blower maintains the flow. The investment in equipment and energy costs is relatively high, and the dry gas after absorbing moisture still has a relatively high temperature. This part of energy It is discharged into the atmosphere without being fully utilized, resulting in energy waste. The dried gas also contains a large amount o...
