In the development and utilization of geothermal energy, saturated drainage is usually regarded as wastewater, which is directly discarded and then recharged underground, and the energy of geothermal water cannot be utilized.

[0006] The recovery equipment includes: saturated water chamber, steam-water separator and large herringbone gear; A water turbine is arranged near the middle of the large herringbone gear; the large herringbone gear and the water turbine are arranged coaxially; The end of the large herringbone gear is meshed and connected with a small herringbone gear; a turbocharger fan is arranged on the small herringbone gear; The water input end of the steam-water separator is connected to the geothermal saturated water source; the water output end of the steam-water separator is connected to the saturated water chamber; the high-temperature air or medium gas output end of the turbo-heating and supercharging fan is connected to the steam output end surface heat exchanger of the steam-water separator; the water input end of the turbine is provided with an inlet regulating valve; The saturated water chamber is connected to the outlet of the water turbine. The geothermal saturated water in the saturated water chamber enters the water turbine, drives the water turbine to operate, drives the large herringbone gear to operate, and then drives the small herringbone gear to operate to achieve the gear speed increase to high speed conversion; The air or medium gas heated and compressed by the turbocharger fan is introduced into the steam-water separator to heat the saturated steam inside the steam-water separator. The air or medium gas is connected to the air or medium gas heater inlet of the saturated water chamber through a pipeline and returns to the inlet volute of the turbocharger fan. It should be further explained that the saturated water chambers are symmetrically arranged on both sides of the turbine of the water turbine, and a saturated water chamber heat exchanger is arranged inside the saturated water chamber to heat the air or medium gas at the inlet of the temperature-increasing supercharger; The two saturated water chambers are also connected to the outlet sides of the turbines of the water turbines respectively.

[0007] It should be further explained that an air or medium gas heating heater is provided inside the steam-water separator.

[0008] It should be further explained that the turbocharger fan is connected to the steam-water separator through an air or medium gas circulation pipeline; and an air or medium gas filter is connected to the air or medium gas circulation pipeline.

[0009] It should be further explained that the two ends of the large herringbone gear are symmetrically meshed to connect the two sets of small herringbone gears; The small herringbone gears are symmetrically arranged with two groups of turbo heating and supercharging fans, and the small herringbone gears are coaxially arranged with the two groups of turbo heating and supercharging fans.

[0010] The present application provides a method for improving the calorific value of geothermal saturated steam and recovering saturated hydrophobic energy, the method comprising: S101: injecting saturated drain water into the steam-water separator, and opening the turbine inlet valve to a first preset opening, the saturated drain water drives the turbine to rotate and then flows into the saturated water chamber, the saturated water pressure is reduced, and evaporates and absorbs heat, and at the same time preheats the air or medium gas in the saturated water chamber; S102: In the preheating stage, the turbine starts to rotate at a preset speed to drive the large herringbone gear, the small herringbone gear and four turbo-heating and boosting fans to operate, heating and compressing the air or medium gas flowing out of the saturated water chamber heat exchanger outlet; S103: Control the valve at the gas input end of the steam-water separator to open, so that the compressed high-temperature air or medium gas enters the heater in the steam-water separator to heat the saturated steam inside the steam-water separator, and the air or medium gas is connected to the air or medium gas heater inlet of the saturated water chamber through a pipeline and returns to the inlet volute of the warming booster fan.

Geothermal saturated water enters the steam-water separator for preliminary separation, and the drain enters the saturated water chamber heater for air or medium gas preheating and recycling. The preheated air or medium gas is heated and compressed by the turbo-heating and boosting fan and then returns to the steam-water separator to heat the steam, and the air or medium gas flows back to the inlet of the heating and boosting compressor through the pipeline.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 Shown is a schematic diagram of a saturated hydrophobic energy recovery device for increasing the calorific value and yield of geothermal saturated steam in a specific embodiment.

[0025] The recovery equipment includes: a saturated water chamber 9, a steam-water separator 6 and a large herringbone gear 2.

[0026] A water turbine 1 is arranged near the middle of the large herringbone gear 2; the large herringbone gear 2 and the water turbine 1 are arranged coaxially.

[0027] The end of the large herringbone gear 2 is meshedly connected with a small herringbone gear 3; a turbocharger fan 4 is provided on the small herringbone gear 3. The turbocharger fan 4 is connected to the steam-water separator 6 through an air or medium gas circulation pipeline 10; an air or medium gas filter 8 is connected to the air or medium gas circulation pipeline 10.

[0028] In this embodiment, two ends of the large herringbone gear 2 are symmetrically meshed to connect two groups of small herringbone gears 3; the small herringbone gears 3 are symmetrically arranged with two groups of turbo heating and supercharging fans 4, and the small herringbone gears 3 are coaxially arranged with the two groups of turbo heating and supercharging fans 4.

[0029] The water input end of the steam-water separator 6 is connected to the geothermal saturated water source; the water output end of the steam-water separator 6 is connected to the saturated water chamber 9 through the inlet pipe of the turbine 1. An air or medium gas heating heater 5 is arranged inside the steam-water separator 6.

[0030] In some embodiments, the water input end of the steam-water separator 6 is directly connected to a geothermal saturated water source, and can receive high-temperature and high-pressure geothermal saturated water. Inside the steam-water separator, the saturated water is separated into steam and drainage. The steam is retained in the steam-water separator, while the drainage is discharged through the water output end and communicated with the saturated water chamber 9 through the outlet of the turbine 1.

[0031] The saturated water chamber 9 of this embodiment is symmetrically arranged on both sides of the water turbine 1, and a saturated water chamber heat exchanger 7 is installed inside. It can receive the drain water from the steam-water separator and transmit it to the water turbine 1 through the inlet pipe of the water turbine 1. The saturated water chamber heat exchanger 7 is installed inside the saturated water chamber 9 to preheat the air or medium gas, and the preheated air or medium gas (original text: air) is connected to the inlet of the temperature increasing and supercharging machine 4 for heating and compression.

[0032] The high-temperature air or medium gas output end of the turbo-heating and supercharging fan 4 is connected to the steam output end interface of the steam-water separator 6; the water input end of the turbine 1 is provided with an inlet regulating valve.

[0033] In some embodiments, the outlet of the water turbine turbine 1 is connected to the saturated water chamber 9. Optionally, the saturated water chambers 9 are symmetrically arranged on both sides of the water turbine turbine 1, and a saturated water chamber air or medium gas heat exchanger 7 is arranged inside the saturated water chamber 9; the two saturated water chambers 9 are also respectively connected to the outlet side of the water turbine turbine 1.

[0034] In this embodiment, the water turbine turbine is linked to the gear system. When the local hot saturated water enters the water turbine turbine 1 and flows out to the saturated water chamber 9, it will drive the turbine to rotate, thereby driving the large herringbone gear 2 to operate. The two ends of the large herringbone gear are symmetrically meshed to connect two sets of small herringbone gears. As the large herringbone gear rotates, the small herringbone gear will rotate at a high speed of 6-10 times the gear speed ratio. The high speed of the small herringbone gear can further increase the preset speed to meet the working requirements of the turbo-heating and boosting fan 4.

[0035] The turbocharger fan 4 of this embodiment is arranged on the small herringbone gear 3 and is coaxially arranged with the small herringbone gear. As the small herringbone gear rotates, the turbocharger fan starts to work, heating and compressing the air or medium gas entering through the air or medium gas circulation pipeline 10. An air or medium gas filter 8 is installed on the air or medium gas circulation pipeline to purify the air or medium gas entering the fan to prevent impurities from damaging the equipment.

[0036] like Figure 2 As shown, the air or medium gas closed cycle in this embodiment is that the air or medium gas circulation pipeline heated and compressed by the turbo heating and boosting fan 4 enters the heating heater 5 in the steam-water separator 6 to heat the saturated steam and saturated hydrophobicity inside. The heated steam increases the calorific value, increases the evaporation of the saturated hydrophobic steam and increases the output. The air or medium gas is connected back to the heating heater 7 in the saturated water chamber 9 through a pipeline, and flows into the inlet pipeline of the heating and boosting machine 4, forming a closed cycle.

[0037] For the heating and hydrophobic separation inside the steam-water separator, it is an open cycle.

[0038] In some specific embodiments, Figure 3As shown, the pressurized water enters the steam-water separator 6, and the saturated drain separated enters the turbine 1, driving the turbine 1 to operate, driving the large herringbone gear 2 to operate, and then driving the small herringbone gear 3 to operate, and increasing the speed of the small herringbone gear 3 to a preset speed. The air or medium gas heated and compressed by the turbocharger fan 4 is introduced into the steam-water separator 6, heating the saturated steam and saturated drain inside the steam-water separator 6. The heated saturated steam increases the calorific value, increases the evaporation of the saturated drain steam to increase the output. After the drain is depressurized after the work of the turbine 1, it enters the saturated drain chamber 9 for further separation, and then drains to the plant area's pressureless drain system.

[0039] It can be seen that the entire equipment realizes the efficient recovery of geothermal saturated steam calorific value and saturated hydrophobic energy of output through the combination of two cycles, a closed cycle of air or medium gas medium and an open cycle of saturated hydrophobic medium.

[0040] The geothermal saturated water in the open circulation medium first enters the steam-water separator for preliminary separation, and then drains into the turbine to work. After working, the saturated water with reduced pressure enters the saturated water chamber to preheat the air or medium gas, and the lower drain port of the pressure-free saturated water chamber is discharged to the plant area.

[0041] The closed-loop medium, air or medium gas, is heated and compressed by the turbocharger fan and then returned to the steam-water separator surface to heat the steam and saturated water. The air or medium gas is returned to the saturated water chamber through the pipeline for preheating and then connected to the turbocharger inlet, where it is reheated and pressurized by the turbocharger to form a closed loop.

[0042] The combined cycle produces steam medium, and the outlet of the steam-water separator is a medium product with increased steam calorific value and output, providing high-quality steam that can be used for subsequent process needs.

[0043] The following is an embodiment of a method for recovering saturated hydrophobic energy for improving the calorific value and output of geothermal saturated steam provided in an embodiment of the present disclosure. This method and the equipment for recovering saturated hydrophobic energy for improving the calorific value and output of geothermal saturated steam in the above-mentioned embodiments belong to the same inventive concept. For details not fully described in the embodiment of the method for recovering saturated hydrophobic energy for improving the calorific value and output of geothermal saturated steam, reference can be made to the embodiment of the equipment for recovering saturated hydrophobic energy for improving the calorific value and output of geothermal saturated steam.

[0044] S101: Inject saturated drain and steam from the pressurized steam source into the steam-water separator 6, and open the inlet valve of the turbine 1 to the first preset opening. The saturated drain drives the turbine 1 to rotate and then flows into the saturated water chamber 9. The saturated water pressure is reduced, and at the same time, the air or medium gas in the saturated water chamber 9 is surface preheated.

[0045] In some embodiments, saturated drain and steam from the pressurized steam source are injected into the steam-water separator 6. Subsequently, the inlet valve of the water turbine 1 is opened to a first preset opening, allowing the saturated drain to enter the water turbine 1. The saturated drain drives the water turbine 1 to rotate during the flow process, thereby converting mechanical energy into kinetic energy. The saturated drain after the work is completed and rotated then flows into the saturated water chamber 9.

[0046] It can be seen that after the saturated water in this embodiment enters the saturated water chamber 9, the surface of the air or medium gas in the saturated water chamber 9 is preheated to prepare for the subsequent heating and pressurizing process of the temperature increasing and compressor.

[0047] S102: During the air or medium gas preheating stage, the turbine 1 starts to rotate at a preset speed to drive the large herringbone gear 2, the small herringbone gear 3 and four turbo-heating and boosting fans 4 to operate, thereby increasing the temperature and pressure of the air or medium gas preheated by the saturated water chamber heat exchanger 7, and recirculating it back to the turbo-charger fan inlet through the outlet, forming a closed-loop preheating and heating process.

[0048] In some embodiments, the preheating stage is based on the water turbine turbine 1 rotating at a preset speed, thereby driving the large herringbone gear 2 and the small herringbone gear 3 and four turbo-heating and boosting fans 4. These fans heat and compress the air or medium gas flowing out of the outlet of the saturated water chamber heat exchanger 7, thereby increasing the temperature and pressure of the air or medium gas (original text: air).

[0049] S103: Control the valve at the air or medium gas input end of the steam-water separator 6 to open, so that the compressed high-temperature air or medium gas (original text: air) enters the surface heat exchanger 5 of the steam-water separator 6, and heats the saturated steam and saturated hydrophobicity inside the steam-water separator 6, so as to increase the calorific value and output of steam at the top of the steam-water separator 6 after the hydrophobicity evaporates.

[0050] In this embodiment, the valve at the air or medium gas input end of the steam-water separator 6 is controlled to be opened and the valve bypass at the air or medium gas atmospheric side is controlled to be closed, so that the high-temperature air or medium gas after heating and compression is introduced into the steam-water separator 6. The high-temperature air or medium gas heats the saturated steam and saturated water in the steam-water separator 6, thereby improving the calorific value and yield of the saturated steam at the top outlet of the steam-water separator 6. The air or medium gas closed cycle obtains the available energy from the saturated water-draining open cycle energy, so as to begin to improve the calorific value and yield of the saturated steam of the steam quality at the outlet of the entire device.

[0051] In some specific embodiments, after the preheating stage is over, the water pipe valve at the turbine inlet is opened at the same time, and the large herringbone gear 2 and the small herringbone gear 3 and the four turbo warming and boosting fans 4 are driven to operate at a preset speed. The air or medium gas at a certain temperature at the outlet of the saturated water chamber heat exchanger 7 can be heated and pressurized, and the temperature gradually exceeds the saturation temperature under a certain pressure, such as saturated water at 0.5Mpa and 150°C, and the compressed air or medium gas needs to be increased to 200-250°C or above.

[0052] Further open the valve at the air or medium gas input end of the steam-water separator 6 to allow high-temperature air or medium gas to enter the steam-water separator, and continuously increase the circulation load as the saturated drain volume increases, continue to open the saturated drain to push the turbine turbine 1 inlet valve to increase the speed by 800 to 1500 rpm, and the speed of the four turbine heating and boosting fans reaches 8000-15000 rpm. The whole system enters a normal circulation operation state, and adjusts the temperature of the air or medium gas entering the steam-water separator by the external air intake volume to achieve safe and economical operation.

[0053] For the control of the temperature, pressure and recycling process in the above steps, this embodiment can be implemented by using a PID control module.

[0054] The temperature in the steam-water separator 6 and the saturated water chamber 9 can be monitored in real time by a temperature sensor, and the temperature signal can be input into the PID controller. The PID controller adjusts the output power of the heating device according to the deviation between the set temperature and the actual temperature to maintain the temperature stability.

[0055] The pressure sensor is used to monitor the pressure changes at the inlet and outlet of the turbine 1 and the steam-water separator 6, and the pressure signal is input into the PID controller. The PID controller adjusts the valve opening or the output flow of the pump according to the deviation between the set pressure and the actual pressure to keep the pressure within the set range.

[0056] The air or medium gas flow rate between the steam-water separator 6 and the turbo-heating and supercharging fan 4 is monitored by a flow sensor to ensure smooth circulation of the high-temperature air or medium gas. The PID controller can adjust the fan speed or valve opening according to the flow change to optimize the circulation efficiency.

[0057] In the method for recovering the saturated drain energy for increasing the calorific value and yield of geothermal saturated steam, the calorific value and thermal energy utilization efficiency of saturated drain for geothermal saturated steam are improved through an energy recovery mechanism that combines a closed loop and an open loop. The application of the PID control module enables precise control of the temperature, pressure and recycling process, enhancing the stability and reliability of the system. The high-temperature air or medium gas after heating and compression increases the calorific value of the steam, which is conducive to meeting the basic and higher requirements for the use of steam in subsequent processes.
