The invention relates to a single shaft work element organic Rankine cycle low quality energy utilization device. The single shaft work element organic Rankine cycle low quality energy utilization device is mainly composed of a low quality energy source, a working medium storage tank, a heat exchanger, a working medium nozzle, a condenser, an overflowing balance tank, a pressure tank, a filter cleaner, a piston, a crank connecting rod, an air cylinder, a control unit and various valves and sensor components, wherein the control unit controls spraying of overheating working mediums so as to constantly achieve different expansion ratios, a vacuum is generated through overexpansion of the overheating working mediums which are high in temperature and high in pressure in a starting stage, a whole pipeline is filled with the working mediums in the starting stage, the overheating working mediums which are high in temperature and high in pressure are fully expanded by controlling flow rate of the overheating working mediums which are sprayed into the air cylinder in a working stage, the piston compresses the liquid working mediums so as to generate high pressure, and a part of the high pressure liquid working mediums compensates the pressure tank for loss. Accordingly, the single shaft work element organic Rankine cycle low quality energy utilization device improves heat efficiency of an organic Rankine cycle, and achieves the purposes of using the low quality energy source and saving energy.
Description
technical field [0001] The invention belongs to the technical field of organic Rankine cycle heat energy utilization, and specifically relates to the development of an organic Rankine cycle heat energy utilization device-a single-axis work element organic Rankine cycle low-quality energy utilization device. Background technique [0002] With the rapid development of the economy, the energy consumption has also increased sharply. Due to the aggravation of energy consumption, the issue of energy saving has attracted people's attention. Relevant research data show that only about one-third of the energy emitted by fuel combustion is effectively used, and the rest of the energy is discharged into the atmosphere, which not only causes waste of energy, but also brings adverse environmental impacts. Therefore, more and more countries pay attention to energy-saving technology. [0003] Since the latent heat of vaporization of the working fluid in the traditional organic Rankine cyc...
