Description

Technical Field

[0001] The present invention relates to the field of geothermal energy technology, and in particular to a geothermal energy buffer storage device and method. Background Art

[0002] With the development of science and technology, people are becoming more and more aware of environmental protection, and are vigorously developing clean energy to meet the needs of daily life. Geothermal energy is achieved by collecting hot steam from the ground, driving the power generation machinery through the collected hot steam, thereby converting thermal energy into electrical energy to ensure people's daily needs.

[0003] For example, Chinese utility model patent CN217844337U discloses a geothermal energy collection, storage and conversion device, which is fixedly arranged at the lower end of a high-pressure absorption tube through an absorption port, and the high-pressure absorption tube is installed under the ground where geothermal energy is generated. The generated steam is absorbed into a low-pressure chamber through a connecting pipe connected to the high-pressure absorption tube, and then the steam is converted through a turbine inside a protective fixed tube.

[0004] However, it still has the following disadvantages. The underground hot steam and hot water usually carry a large amount of minerals and impurities. The long-term absorption of geothermal energy into the low-pressure chamber will cause a large amount of impurities to accumulate on the inner wall of the chamber, thereby corroding the chamber and reducing the service life of the device.

[0019] Step 1: The electric valve of the pipeline device of the cleaning component provides power to drive the valve ball 1 to rotate in the pipeline 1. The rotation of the valve ball 1 guides the water flow from the pipeline 2 to the water delivery pipe of the cleaning device. At this time, the water flows into the cleaning device through the movable water pipe and is sprayed out through the nozzle 1 and the nozzle 2 fixed on the fixed plate. The reaction force of the water spraying from the nozzle 2 drives the water storage bin to rotate on the support block. At the same time, the reaction force of the water spraying from the nozzle 1 drives the movable water pipe to rotate on the water delivery pipe. When water and hot steam begin to be stored in the device, the pipeline 1 is driven to rotate through the electric valve. At this time, the water flow and steam press the blocking block to move to the left. At the same time, the spring on the left end support plate is compressed by the blocking block to shrink. At the same time, the blocking block drives the slider to slide in the slide groove. When the device stops storing water and hot steam, the spring is no longer compressed and drives the blocking block to move right to cooperate with the support plate at the right end to seal. When the pressure in the device is too large, the pressure sensor is compressed and drives the electric valve to rotate to seal the pipeline 1.

[0020] Step 2: The steam flows into the exhaust pipe of the exhaust device to drive the fan blades to flow. When the gas flow rate is too fast, the fan blades are driven to rotate quickly to control the start of the electric valve 2. At this time, the electric valve 2 drives the support plate to rotate, and the rotation of the support plate drives the connecting rod 1 to rotate. The rotation of the connecting rod 1 drives the connecting rod 2 to move left. The left movement of the connecting rod 2 drives the sealing plug to move along the limiting sliding groove provided on the exhaust pipe, and the sealing plug that moves left cooperates with the sealing blocking block to reduce the amount of steam discharged;

[0021] Step 3: Unlock the funnel and the cover plate by turning the bolts of the quantitative feeding device. At this time, the cover plate is driven to rotate on the funnel through the hinge to open the dosing. When the dosing is completed, the cover plate is turned to cover the funnel and sealed and fixed by turning the bolts. When the device is ready to be cleaned, the storage tank is driven to rotate by starting the motor to add the powder into the storage barrel. The function of the baffle is to prevent the powder from leaking from the funnel;

[0022] Step 4: The thermistor of the drainage device detects a drop in water temperature. At this time, the circuit is turned on to start the timer, which in turn starts the electric valve three to open the drain pipe. After a period of time, the timer starts again to drive the electric valve three to close the drain pipe.

[0023] The present invention has the following technical effects:

[0024] 1. The present invention provides power through the electric valve of the pipeline device of the cleaning component to drive the valve ball 1 to rotate in the pipeline 1. The rotation of the valve ball 1 guides the water flow from the pipeline 2 to the water delivery pipe of the cleaning device. At this time, the water flows into the cleaning device through the movable water pipe and is sprayed through the nozzle 1 and the nozzle 2 fixed on the fixed plate. Due to the reaction force of the water spraying of the nozzle 2, the water storage bin is driven to rotate on the support block. At the same time, the reaction force of the water spraying of the nozzle 1 drives the movable water pipe to rotate on the water delivery pipe. When water and hot steam begin to be stored in the device, the pipeline 1 is driven to rotate through the electric valve. At this time, the water flow and steam press the blocking block to move to the left, and at the same time, the blocking block is pressed by the electric valve. The blocking block compresses the spring on the left end support plate to contract, and at the same time, the blocking block drives the slider to slide in the slide groove. When the device stops storing water and the hot steam ends, the spring is no longer compressed and drives the blocking block to move right to cooperate with the support plate on the right end to seal. When the pressure in the device is too high, the pressure sensor is compressed and drives the electric valve to rotate to seal the pipeline. By cleaning the inner wall of the device, the accumulation of minerals and impurities brought by underground hot water can prevent the inner wall of the device from corroding and affecting its life. When the water and steam injection is stopped, the device is sealed to avoid gas leakage and waste. At the same time, when the pressure in the device is too high, the electric valve sealing device is controlled to prevent it from rupturing due to excessive pressure.

[0025] 2. The present invention drives the fan blades to flow by flowing steam into the exhaust pipe of the exhaust device. When the gas flow rate is too fast, the fan blades are driven to rotate quickly to control the start-up of electric valve two. At this time, electric valve two drives the support plate to rotate, and the rotation of the support plate drives the connecting rod one to rotate, and the rotation of the connecting rod one drives the connecting rod two to move left, and the left movement of the connecting rod two drives the sealing plug to move along the limiting slide groove provided on the exhaust pipe, and the sealing plug that moves left cooperates with the sealing blocking block to reduce the amount of steam discharged, and the opening size of the control device is controlled to control the speed of steam outflow, so as to avoid excessive steam outflow due to excessive air pressure. Excessive steam outflow cannot improve the power generation efficiency, but will cause waste of steam.

[0026] 3. The present invention releases the lock of the funnel and the cover plate by rotating the bolts of the quantitative feeding device. At this time, the cover plate is driven by the hinge to rotate on the funnel to open the medicine adding. When the medicine adding is completed, the cover plate is covered on the funnel by rotating and sealed by rotating the bolts. When the device is ready to be cleaned, the storage tank is driven to rotate by starting the motor to add the powder into the storage barrel. The baffle plate prevents the powder from leaking from the funnel. Through the automatic quantitative medicine adding of the device, the powder can be added according to the demand to avoid the waste caused by excessive addition of powder, and at the same time improve the accuracy of medicine adding.

[0062] Please refer to the instruction manual Figure 1-9 The present invention provides a method for the geothermal energy buffer storage device, comprising the following steps:

[0063] Step 1: The electric valve 213 of the pipeline device 21 of the cleaning component 2 provides power to drive the valve ball 1 212 to rotate in the pipeline 1 211. The rotation of the valve ball 1 212 guides the water flow from the pipeline 214 to the water delivery pipe 221 of the cleaning device 22. At this time, the water flows into the cleaning device 22 through the movable water pipe 226 and is sprayed out through the nozzle 1 223 and the nozzle 224 fixed on the fixed plate 227. Due to the reaction force of the water spraying of the nozzle 224, the water storage tank 222 is driven to rotate on the support block 225. At the same time, the reaction force of the water spraying of the nozzle 1 223 drives the movable water pipe 226 to rotate on the water delivery pipe 221. When water and hot steam start to be stored in the device, the electric valve 213 drives the pipe 1 211 to rotate. At this time, the water flow and steam compress the blocking block 217 to move to the left. At the same time, the blocking block 217 compresses the spring 216 on the left end support plate 215 to contract. At the same time, the blocking block 217 drives the slider 219 to slide in the slide groove 218. When the device stops storing water and hot steam, the spring 216 is no longer compressed and drives the blocking block 217 to move right to cooperate with the support plate 215 at the right end to seal. When the pressure in the device is too high, the pressure sensor 210 is compressed and drives the electric valve 213 to rotate to seal the pipe 1 211.

[0064] Step 2: The steam flows into the exhaust pipe 51 of the exhaust device 5 to drive the fan blade 53 to flow. When the gas flow rate is too fast, the fan blade 53 is driven to rotate quickly to control the electric valve 2 52 to start. At this time, the electric valve 2 52 drives the support plate 57 to rotate, and the rotation of the support plate 57 drives the connecting rod 1 58 to rotate. The rotation of the connecting rod 1 58 drives the connecting rod 2 59 to move leftward. The leftward movement of the connecting rod 2 59 drives the sealing plug 55 to move along the limiting slide groove 56 provided on the exhaust pipe 51. The sealing plug 55 that moves leftward cooperates with the sealing blocking block 54 to reduce the amount of steam discharged.

[0065] Step 3: The lock between the funnel 32 and the cover plate 35 is released by rotating the bolt 37 of the quantitative feeding device 3. At this time, the cover plate 35 is driven to rotate on the funnel 32 through the hinge 36 to open the medicine addition. When the medicine addition is completed, the cover plate 35 is covered on the funnel 32 by rotating it and sealed and fixed by rotating the bolt 37. When the device is ready to be cleaned, the storage tank 33 is driven to rotate by starting the motor 1 31 to add the powder into the storage barrel 1. The baffle 34 is used to prevent the powder from leaking from the funnel 32.

[0066] Step 4: The thermistor 42 of the drainage device 4 detects a drop in water temperature. At this time, the circuit is turned on to start the timer 43, and the electric valve three 44 is started by the timer 43 to open the drain pipe 41. After a period of time, the timer 43 is started again to drive the electric valve three 44 to close the drain pipe 41.

4. A method of geothermal energy buffer storage device as claimed in claim 3, comprising the following steps: Step 1: The electric valve (213) of the pipeline device (21) of the cleaning component (2) provides power to drive the valve ball 1 (212) to rotate in the pipeline 1 (211). The rotation of the valve ball 1 (212) guides the water flow from the pipeline 2 (214) into the water delivery pipe (221) of the cleaning device (22). At this time, the water flows into the cleaning device (22) through the movable water pipe (226) and is sprayed out through the spray head 1 (223) and the spray head 2 (224) fixed on the fixing plate (227). Due to the reaction force of the spraying of the spray head 2 (224), the water storage tank (222) is driven to rotate on the support block (225). At the same time, the reaction force of the spraying of the spray head 1 (223) drives the movable water pipe (226) in the water delivery pipe (2 21) rotates, and when water and hot steam begin to be stored in the device, the electric valve (213) drives the pipeline 1 (211) to rotate. At this time, the water flow and steam compress the blocking block (217) to move to the left, and at the same time, the blocking block (217) compresses the spring (216) on the left end support plate (215) to shrink. At the same time, the blocking block (217) drives the slider (219) to slide in the slide groove (218). When the device stops storing water and hot steam, the spring (216) is no longer compressed and drives the blocking block (217) to move right to cooperate with the support plate (215) at the right end to seal. When the pressure in the device is too high, the pressure sensor (210) is compressed and drives the electric valve (213) to rotate to seal the pipeline 1 (211); Step 2: Steam flows into the exhaust pipe (51) of the exhaust device (5) to drive the fan blade (53) to flow. When the gas flow rate is too fast, the fan blade (53) is driven to rotate quickly, thereby controlling the start of the electric valve 2 (52). At this time, the electric valve 2 (52) drives the support plate (57) to rotate, and the rotation of the support plate (57) drives the connecting rod 1 (58) to rotate. The rotation of the connecting rod 1 (58) drives the connecting rod 2 (59) to move leftward. The leftward movement of the connecting rod 2 (59) drives the sealing plug (55) to move along the limiting sliding groove (56) provided on the exhaust pipe (51). The sealing plug (55) that moves leftward cooperates with the sealing blocking block (54) to reduce the amount of steam discharged; Step 3: The locking between the funnel (32) and the cover plate (35) is released by rotating the bolt (37) of the quantitative feeding device (3). At this time, the cover plate (35) is driven by the hinge (36) to rotate on the funnel (32) to open and add medicine. When the addition of medicine is completed, the cover plate (35) is covered on the funnel (32) by rotating and sealed by rotating the bolt (37). When the device is ready to be cleaned, the storage tank (33) is driven to rotate by starting the motor 1 (31) to add the medicine powder into the storage barrel (1). The baffle (34) is used to prevent the medicine powder from leaking from the funnel (32); Step 4: The thermistor (42) of the drainage device (4) detects a drop in water temperature. At this time, the circuit is turned on to drive the timer (43) to start, and the timer (43) drives the electric valve three (44) to start, opening the drainage pipe (41). After a period of time, the timer (43) is started again to drive the electric valve three (44) to close the drainage pipe (41).
