Gas compressing device special for gas power generation

Abstract

The invention discloses a gas compressing device special for gas power generation. The gas compressing device comprises a protective shell, a pressurizing cavity is arranged in the protective shell, adriving impeller, a balance impeller and a conveying impeller are sequentially arranged in the pressurizing cavity, the driving impeller is connected with the balance impeller through a first guide rod, the balance impeller is connected with the conveying impeller through a second guide rod, air inlet pipelines are arranged at the upper end and the lower end of the front side of the pressurizingcavity, a driving motor is arranged on the outer wall of the center of the front side of the pressurizing cavity and connected with the driving impeller, and a diffuser is arranged on the rear side ofthe pressurizing cavity, corresponds to the conveying impeller and is connected with an air outlet pipe. The gas compressing device is simple in structure and novel in design, the driving impeller, the balance impeller and the conveying impeller are connected with one another to replace a traditional connecting structure of the impeller and a flow regulating device, so that mutual interference caused by unstable gas pressure between the blades and the flow regulating device is effectively eradicated, and the pressurizing efficiency of the whole air compressing device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a special compressor for gas-fired power generation. Background technique [0002] With the development and application of natural gas resources, the use of gas-fired generator sets will gradually increase in my country's power system, and the role of gas-fired power generation in my country's power industry will gradually increase; its working principle is to transport gas to thermal power generation devices for combustion In the cavity, the heat generated by the full combustion of gas is used to convert heat energy into mechanical energy to achieve the purpose of power generation; [0003] In order to improve the combustion efficiency of gas, it is necessary to pressurize the transported gas to increase the pressure of the whole gas, but the efficiency of the existing compressor is low, and the vibration of the whole compressor is relatively large during operati...

Problems solved by technology

[0003] In order to improve the combustion efficiency of gas, it is necessary to pressurize the transported gas to increase the pressure of the whole gas, but the efficiency of the existing compressor is low, and the vibration of the whole compressor is relatively large during operation, so it is easy to cause the blades to be affected by the vibration. produce cracks;

[0004] Existing air compressors usually connect the blades with the rectifier to maintain the balance of the air pressure inside the entire device. However, after a long working time, there will be some interference between the blades and the rectifier, which will affect the boosting effect of the entire compressor.
