Description
技术领域technical field
本实用新型涉及一种多级轴流压气机，具体涉及一种间冷式多级轴流压气机。The utility model relates to a multistage axial flow compressor, in particular to an intercooled multistage axial flow compressor.
背景技术Background technique
压气机在化学工业和能源行业中广泛使用，它是布雷顿循环系统、远程气体输送系统以及化工系统中为气态或超临界态流体增加压力的重要的旋转机械设备。在采用多级轴流压气机，对气态或超临界态流体增压的过程中，流体的温度会相应升高，而温度的升高导致流体进一步被压缩的功耗增大。在超临界二氧化碳临界点附近，压缩二氧化碳所需功耗随温度升高迅速增加，若能采用适合的方法降低流体的温度，可以大大降低压缩功耗，提升循环系统的效率。为了降低压缩功耗，研究人员提出了间冷技术，即为：将流体在大型压气机的低压压气机出口引出进行冷却，冷却后再将流体送至高压压气机的进口，由高压压气机对流体进行提升压力。现有压气机的间冷技术所需空间较大，结构复杂，所以仅能应用于电站燃气轮机或舰船燃气轮机的低压压气机和高压压气机之间。上述技术，虽能在一定程度上减少高压压气机的功耗，但不能用于降低低压压气机功耗，而且流体流经间冷通道时会还必然带来一定的压力损耗。Compressors are widely used in the chemical industry and energy industry. It is an important rotating mechanical device for increasing the pressure of gaseous or supercritical fluids in Brayton cycle systems, remote gas delivery systems, and chemical systems. In the process of pressurizing a gaseous or supercritical fluid with a multi-stage axial flow compressor, the temperature of the fluid will increase accordingly, and the increase in temperature will lead to an increase in power consumption for further compression of the fluid. Near the critical point of supercritical carbon dioxide, the power consumption required to compress carbon dioxide increases rapidly with the increase of temperature. If a suitable method can be used to reduce the temperature of the fluid, the compression power consumption can be greatly reduced and the efficiency of the circulation system can be improved. In order to reduce the compression power consumption, the researchers proposed the intercooling technology, that is, the fluid is drawn out from the outlet of the low-pressure compressor of the large compressor for cooling, and then the fluid is sent to the inlet of the high-pressure compressor after cooling, and the high-pressure compressor The fluid carries on lifting pressure. The existing intercooling technology for compressors requires a large space and has a complex structure, so it can only be applied between the low-pressure compressor and the high-pressure compressor of a gas turbine in a power station or a gas turbine in a ship. Although the above technology can reduce the power consumption of the high-pressure compressor to a certain extent, it cannot be used to reduce the power consumption of the low-pressure compressor, and the fluid flowing through the intercooling channel will inevitably bring a certain pressure loss.
