DETAILED DESCRIPTION

[0014] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0015] Combined with attachment Figure 1 To the attached Figure 3 As shown, a thermal cycle device for supercritical water pulse detonation includes a first heat transfer pipe 41 connected to a heating chamber 10 and a second heat transfer pipe 42 connected to a combustion chamber 30. The heating chamber 10 is used to heat water to produce supercritical water, and the combustion chamber 30 is used to burn combustible gases generated by decomposing organic pollutants.

[0016] A heat pump 43 is provided between the first heat transfer pipe 41 and the second heat transfer pipe 42 . The heat pump 43 has an input port 431 and an output port 432 . The input port 431 of the heat pump 43 is connected to the second heat transfer pipe 42 , and the output port 432 of the heat pump 43 is connected to the first heat transfer pipe 41 .

[0017] A pulse detonation chamber 20 is located between the heating chamber 10 and the combustion chamber 30. The heating chamber 10 converts water into supercritical water at a temperature of 374.3°C and a pressure of 22.05 MPa. A vigorous oxidation reaction occurs within the pulse detonation chamber 20. Supercritical water oxidation technology can transform toxic and hazardous organic matter in wastewater into easily degradable small molecules through ring opening, bond scission, substitution, and electron transfer. The reaction can even be directly converted into water and carbon dioxide, achieving the desired treatment effect. The converted water can then be discharged directly from the front end of the combustion chamber 30.

[0018] Since wastewater may contain nitro compounds (such as TNT) or nitrogen-rich organic matter, some N₂H₄ or NH₃ will be released during the initial oxidation reaction, requiring further treatment. The combustion chamber 30 uses an igniter to ignite the N₂H₄ or NH₃ within the chamber. The heat energy from the ignition is transferred via the second heat transfer pipe 42 to the heat pump 43, which then pumps the heat energy to the first heat transfer pipe 41. This heat energy is then transferred to the heating chamber 10, where it is used to heat the water in the heating chamber 10 to supercritical water, achieving energy recycling.

[0019] Combined with attachment Figure 2 and attached Figure 3 As shown, the heat pump 43 is equipped with a blower box 44 for pumping heat energy. A heat pump motor 45 is connected to the blower box 44. The heat pump motor 45 is located at one end of the blower box 44, and the first heat transfer pipe 41 is located at the other end of the blower box 44. A gear mechanism is housed within the blower box 44. A lubrication hole for adding grease to the gear mechanism is provided in the blower box 44, and a cover 441 is provided over the lubrication hole. A connecting bracket 46 is provided between the heat pump motor 45 and the blower box 44.

[0021] It should be understood that, while the present invention uses terms such as "first" and "second" to describe various types of information, such information should not be limited to these terms; these terms are merely used to distinguish information of the same type from one another. For example, "first" information could also be referred to as "second" information, and similarly, "second" information could also be referred to as "first" information without departing from the scope of the present invention.
