Drawings
Fig. 1 is a block diagram of a heat transfer working medium integrated supply system of a stirling engine in an embodiment of the invention.
Detailed Description
The present invention will be further described with reference to the following embodiments and drawings, and more details will be set forth in the following description in order to provide a thorough understanding of the present invention, but it is obvious that the present invention can be implemented in various other ways different from those described herein, and those skilled in the art can make similar generalizations and deductions according to the actual application without departing from the spirit of the present invention, and therefore, the scope of the present invention should not be limited by the contents of the embodiments.
As shown in fig. 1, the heat transfer working medium integrated supply system of the stirling engine comprises a hydrogen generator 1, a gas storage tank 2, a gas outlet main pipe 3 and a gas return main pipe 4.
The hydrogen generator 1 generally includes an electrolytic cell, a pure water tank, a hydrogen/water separator, a collector, a dryer, a sensor, a pressure regulating valve, a switching power supply, and the like. Which can produce hydrogen by electrolyzing pure water. After the power is switched on, the cathode of the electrolytic cell produces hydrogen, the anode produces oxygen, and the hydrogen enters the hydrogen/water separator. Oxygen is vented to the atmosphere. The hydrogen/water separator separates hydrogen and water. After the hydrogen enters the dryer for dehumidification, the hydrogen is regulated to rated pressure (adjustable at 0.02-0.45 Mpa) through a pressure stabilizing valve and a regulating valve and is output to the gas storage tank 2 through an outlet. The hydrogen production pressure of the electrolytic cell is controlled by a sensor, and when the pressure reaches a set value, the power supply of the electrolytic cell is cut off; and the pressure is reduced, and the power supply is restored to supply power when the pressure is lower than the set value.
