The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments alone or selectively.

[0023] Embodiment 1

[0025] In this embodiment, the core structure of the device consists of a housing assembly 100, a power generation assembly 200, and a noise reduction assembly 300. The housing assembly 100 provides support and protection for the device, and houses the power generation and noise reduction components inside, enabling the device to work safely and stably in a high-pressure exhaust environment. The power generation assembly 200 captures the exhaust energy through the energy absorption member 201 and transfers it to the energy storage member 202 to achieve energy conversion and storage. The energy absorption member 201 is located on the front side of the energy storage member 202 to ensure that the exhaust energy can be directly transferred into the generator system. The noise reduction assembly 300 is arranged inside the housing assembly 100 to reduce the noise interference generated during the exhaust process, enabling the system to achieve the effects of energy conservation and noise reduction.

[0026] Embodiment 2

[0027] Refer to 1~ Figure 2 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0028] Specifically, the housing assembly 100 includes an intake pipe 101, an internal channel 103, a noise reduction chamber 102, and an exhaust pipe 104. The intake pipe 101 is arranged at the front end of the internal channel 103, the noise reduction chamber 102 is arranged at one end of the internal channel 103, and the exhaust pipe 104 is arranged at the tail of the noise reduction chamber 102;

[0029] The noise reduction chamber 102 adopts a strong metal structure, having good rigidity and seismic resistance. The intake pipe 101 accesses the high-pressure gas tank exhaust, is transmitted through the internal channel 103 to the noise reduction chamber 102, and is discharged from the exhaust pipe 104 after noise reduction treatment. This structure ensures the stability of the exhaust process and effective noise control;

[0030] It is worth noting that the intake pipe 101 is made of high-strength and high-pressure-resistant materials, such as stainless steel, to ensure safety and stability during high-pressure gas transmission. Its inner wall is smooth to reduce the resistance of gas flow and improve the energy transfer efficiency.

[0031] Specifically, a pressure regulating valve 101a is arranged inside the intake pipe 101;

[0032] By adjusting the gas pressure entering the system, the operation of the system under different working conditions is optimized to ensure the stability of the system.

[0033] Specifically, a placement layer 103a is provided on the outer side of the internal channel 103, and the placement layer 103a communicates with the internal channel 103 through a connection groove 103b.

[0034] Specifically, the energy-absorbing member 201 includes a turbine group 201a and a universal joint 201b. The turbine group 201a is rotatably arranged at one end of the internal channel 103 close to the intake pipe 101, and one end of the universal joint 201b is connected to the rotating shaft of the turbine group 201a;

[0035] When high-pressure gas enters the expander, it pushes the turbine group 201a to rotate and do work, gradually converting the pressure energy of the gas into mechanical energy, and transmitting power through the universal joint 201b.

[0036] Specifically, the turbine group 201a adopts a multi-stage turbine structure, and along the direction from one end of the intake pipe 101 to one end of the noise reduction chamber 102, the diameter of each stage of the turbine gradually increases; one end of the internal channel 103 close to the turbine group 201a is set as a conical surface 103c, and the shape of the conical surface matches that of the turbine group 201a;

[0037] It should be noted that stator blades (not shown in the figure) are also provided between adjacent turbines. The steam passing through the turbine blades is forced into the cavity of the stator blades, so that the speed of the fluid increases again, playing an accelerating role. As the steam gradually moves, its pressure rapidly decreases and its volume increases. Therefore, the blade diameter of the turbine group 201a gradually increases; the conical surface 103c is used to control the steam flow to the blades of the turbine group 201a; in addition, each stage of the turbine and the stator blades are made of high-strength and lightweight materials, such as titanium alloy reinforced composites, to withstand the impact of high-speed rotation and high-pressure gas, reduce the moment of inertia, and improve the energy conversion efficiency.

[0038] Specifically, the energy storage member 202 includes a generator 202a and a storage battery 202b. The generator 202a and the storage battery 202b are arranged in the placement layer 103a. One end of the universal joint 201b away from the turbine group 201a is connected to the rotor of the generator 202a, and the storage battery 202b is electrically connected to the generator 202a;

[0039] The generator 202a adopts an efficient permanent magnet synchronous generator or an excitation synchronous generator, which has high power density, high efficiency and good dynamic response characteristics. The electric energy output by it can be directly incorporated into the storage battery 202b after rectification, filtering and voltage stabilization processing for use by the control unit.

[0040] Specifically, the noise reduction component 300 includes a noise reduction layer 301, a noise acoustic wave sensor 302, a frequency converter 303, and a muffler 304. The noise reduction layer 301 is disposed on the outer side of the housing component 100. The noise acoustic wave sensor 302 is disposed on one side of the internal channel 103 close to the noise reduction chamber 102. The frequency converter 303 is disposed in the noise reduction chamber 102. The muffler 304 is disposed on the exhaust pipe 104.

[0041] By installing the noise acoustic wave sensor 302, the noise acoustic wave is monitored in real time, and the frequency converter 303 is used to generate a sound wave with the opposite phase to cancel it, so as to achieve a more accurate and efficient noise reduction effect. The muffler reduces noise by changing the propagation path and reflection characteristics of the sound wave.

[0042] Specifically, the noise reduction layer 301 includes a sound absorption layer 301a, a sound insulation layer 301b, and a damping layer 301c. The sound absorption layer 301a is composed of a material with good sound absorption effect, such as a polyester fiber sound absorption board, and is used to absorb the noise generated inside. The sound insulation layer 301b uses a heavy sound insulation material, such as a lead plate or concrete, to prevent the noise from spreading outwards. The damping layer 301c reduces the structural vibration and noise radiation by consuming the vibration energy. When in use.

[0044] Referring to Figure 3 , this is the third embodiment of the present invention. This embodiment provides an operating system for high-pressure gas tank exhaust energy recovery and noise reduction, which includes a high-pressure gas tank exhaust energy recovery and noise reduction device, and also includes a control unit 400, which includes a sensor module 401, a data processing module 402, and a control execution module 403. The sensor module 401 is used to collect the intake pressure, temperature, turbine group speed, output power of the generator 202a, and exhaust pressure. The data processing module 402 performs real-time analysis and processing on the collected data, and calculates a control instruction according to a preset control strategy. The control execution module 403 adjusts the working states of the pressure regulating valve 101a, the generator 202a, and the frequency converter 303 according to the control instruction to achieve the optimized operation and automatic protection of the device;

[0045] The control unit 400 is responsible for the overall monitoring and automatic control of the device. Through the sensor module 401, the system collects the operating parameters of the device, including information such as pressure and temperature. The data processing module 402 analyzes the real-time data and generates a control instruction. The control execution module 403 adjusts the state of the device components according to the instruction to realize the intelligentization of energy recovery and noise reduction control.
