Double-stage steam compressor device

Abstract

The invention relates to a double-stage steam compressor device which comprises a base, a motor and a first-stage compressor head. The motor and the first-stage compressor head are installed on the base. The first-stage compressor head is provided with a first-stage diffusion runner and a first-stage impeller located in the runner. The first-stage diffusion runner is provided with a first-stage inlet and a first-stage outlet. The double-stage steam compressor device further comprises a second-stage compressor head of the base and a connecting channel. The second-stage compressor head is provided with a second-stage diffusion runner and a second-stage impeller located in the runner. The second-stage diffusion runner is provided with a second-stage inlet and a second-stage outlet. The motoris provided with a first output end for driving the first-stage impeller to rotate, and a second output end for driving the second-stage impeller to rotate. According to the double-stage steam compressor device, by means of a mechanical structure, the problems of high energy consumption and high maintenance cost are solved, and the fundamental purposes of effectively reducing the energy consumption and maintaining cost are achieved.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a two-stage steam compressor device. Background technique [0002] In recent years, due to the increasing demand of human beings for energy, energy supply has become a bottleneck problem. Faced with such a situation, energy saving has become one of the effective ways to get rid of the shackles of energy shortage. Among them, vapor compression technology is an efficient and environmentally friendly energy-saving technology, which is currently being widely used in the MVR process of traditional Chinese medicine concentration. [0003] The vapor compression technology currently used in the traditional Chinese medicine concentration MVR process usually uses a conventional motor with a speed-increasing gearbox to drive a single impeller shaft, so that the impeller passing through the volute diffuser rotates in the compressor head, and at the same time in the thin oil station ...

AI Technical Summary

Problems solved by technology

[0004] The overall pressurization process is completed by a single impeller in one compressor head, so in order to ensure the effect of pressurization, the impeller needs a large output power of the motor, which requires a lot of energy consumption

And because the output shaft of the motor and the impeller shaft are speeded up through the speed-increasing gearbox, not only is there a waste of energy in the transmission process, but also the many internal parts of the gearbox will inevitably lead to failures, making the failure rate of the compressor High maintenance, coupled with the wear and tear of various components during the pressurization process, resulting in high maintenance costs and hindering economic benefits
