Description

Technical Field

[0001] The invention relates to the technical field of underground thermal energy utilization, and in particular to a geothermal coupled heat pump unit heating system. Background Art

[0002] Biomass gasification refers to the process of converting biomass raw materials such as wood and crop straw into combustible gases under certain conditions. These combustible gases can be used to burn and generate heat energy. Medium-deep geothermal energy refers to geothermal resources located deep underground (usually more than one kilometer). Its temperature is relatively high and stable. After coupling the heat pump unit, the two different types of energy, biomass and medium-deep geothermal energy, can be comprehensively utilized, reducing dependence on a single energy source and improving the stability of energy supply. In other words, in periods of insufficient supply of biomass raw materials, medium-deep geothermal energy can be relied on to ensure heating, and vice versa.

[0003] In the prior art, such as the Chinese patent number: CN220287799U, a medium-deep geothermal energy and shallow geothermal energy coupling energy supply system is disclosed, including a medium-deep geothermal buried pipe, a shallow geothermal buried pipe and a heat pump unit. The input end of the medium-deep geothermal buried pipe and the input end of the shallow geothermal buried pipe are connected in parallel to form a geothermal input end, and the output end of the medium-deep geothermal buried pipe and the output end of the shallow geothermal buried pipe are connected in parallel to form a geothermal output end. The geothermal input end and the geothermal output end are respectively connected to the two ends of the heat pump unit to form a loop. This medium-deep geothermal energy and shallow geothermal energy coupling energy supply system effectively combines and connects the shallow geothermal buried pipe and the medium-deep geothermal buried pipe by setting, so that the geothermal water of the shallow geothermal buried pipe and the medium-deep geothermal buried pipe can be refluxed after passing through the heat pump unit, and the geothermal water of the two can be combined together to achieve coupling between the two.

[0004] However, in the existing technology, the coupling of biomass gasification and medium-deep geothermal heat requires the use of heat pump units to achieve heating. The combination of the two methods can not only improve the stability of energy supply, but also save the cost of heat generation. When the heat pump unit brings underground heat energy to the ground for use, it will quickly heat the water in the water tank to realize the utilization of heat. However, the capacity of the current water tank is very large. When the underground heat is not enough, the water inside the entire water tank cannot be heated, resulting in instability in the demand for heat energy, and the space inside the water tank cannot be adjusted, lacking flexibility in use.

An air pump 406 is arranged on the outer surface of the water tank 301 near the air cavity 401. The output port of the air pump 406 is fixedly connected to an air delivery pipe 405. An electromagnetic valve 404 is arranged on the outer surface of the air delivery pipe 405, and the electromagnetic valve 404 is used to control the direction of air intake. The top of the air cavity 401 is fixedly connected to two connecting ports, and a connecting pipe 403 is fixedly connected between the tops of the two connecting ports. The connecting pipe 403 is used to inject air into the space on both sides of the piston 407. One end of the air delivery pipe 405 is fixedly penetrated into the interior of the connecting pipe 403. The heat transfer component 6 includes two spiral conveying pipes 601, and one end of one of the spiral conveying pipes 601 is fixedly connected to one end of the heat transfer pipe 2.One of the spiral conveying pipes 601 is used to transfer the heat transported by the heat pump body 1 coupled to the geothermal to the inside of the water tank 301, and one end of the other spiral conveying pipe 601 is fixedly connected to one end of the second drain port 307. Limiting frames 602 are arranged outside the two spiral conveying pipes 601, and the two limiting frames 602 are used to stabilize the two spiral conveying pipes 601. One end of the two spiral conveying pipes 601 is fixedly connected to a connecting pipe 604, and the two connecting pipes 604 are made of hard waterproof stainless steel metal. A soft pipe 605 is fixedly connected between the opposite ends of the two connecting pipes 604. The soft pipe 605 is made of a soft waterproof and corrosion-resistant rubber material. The soft pipe 605 matches the position of the card slot 414. Multiple fixing rods 603 are fixedly connected to both sides of the two limit frames 602. The multiple fixing rods 603 are evenly symmetrically divided into two groups. Each group of fixing rods 603 is fixedly connected to the opposite inner wall of the water storage tank 301. The heat pump body 1 is used for coupling and transmitting underground heat. One end of the heat pump body 1 is fixedly connected to a heat transfer pipe 2, and the heat transfer pipe 2 is used to further transport the underground heat transported by the heat pump body 1. One end of the heat transfer pipe 2 passes through the water storage tank 301 to its interior.

[0024] In this embodiment, when in use, by starting the heat pump body 1, it is coupled with the geothermal energy, and the geothermal energy provides a relatively low-temperature but stable source of heat energy, and the heat pump body 1 can raise this part of the low-temperature heat energy to a higher temperature, thereby meeting the heating demand. The heat transfer pipe 2 plays the role of transporting heat energy, and the heat energy is transferred back to the spiral conveying pipe 601. Under the connection between the connecting pipe 604 and the soft pipe 605, each spiral conveying pipe 601 is connected, so that heat can be transported inside it. The spiral conveying pipe 601 is inside the water storage tank 301, so the heat is dissipated inside the water storage tank 301 to heat the water inside the water storage tank 301. At this time, the partition plate 409 is in a contracted state. When the heat is not enough to heat all the water inside the water storage tank 301, the air pump 406 is started. After the air is taken in, the gas is pressurized and output from the air delivery pipe 405. By electrically connecting the solenoid valve 404 with the controller 309, when the solenoid valve 404 is closed, the airflow enters the piston When the electromagnetic valve 404 is opened, the air flow direction in the connecting pipe 403 changes, and the piston 407 moves in the opposite direction, thereby driving the sliding rod 408 to move the partition plate 409 in the opposite direction until the three sides of the partition plate 409 are in close contact with the inner wall of the water storage tank 301. The sealing ring 415 plays a role in preventing water leakage at this time, and can completely separate the water storage tank 301 into two areas, and only heat the water in one area, thereby speeding up the heating speed by reducing the amount of heated water. At this time, the card slot 414 clamps the soft pipe 605. After the soft pipe 605 is clamped, the heat is concentrated in the spiral conveying pipe 601 in one area, and the remaining heat is slowly discharged from the other spiral conveying pipe 601, which solves the problem that the internal space of the existing hot water storage tank cannot be adjusted and changed, and can ensure stable heating.

Two reinforcing sleeves 304 are sleeved near the top of the water tank 301, and both ends of the two reinforcing sleeves 304 are fixedly connected to mounting blocks 305. The four mounting blocks 305 are respectively fixedly connected to the two ends of the two mounting frames 302 by bolts. The front surface of the water tank 301 is fixedly connected to a first drain port 306, and the first drain port 306 is used to drain the water inside the water tank 301. A space is used for drainage, one side of the water tank 301 is fixedly connected with a second drain port 307, and the second drain port 307 is used to drain the entire water tank 301, a temperature sensor 308 is arranged on the top of the water tank 301, the temperature sensor 308 is used to timely monitor the water temperature inside the water tank 301, a controller 309 is arranged on the top of the water tank 301 near the temperature sensor 308, the output end of the temperature sensor 308 is electrically connected to the input end of the controller 309, and a closed window 310 is opened on the front surface of the water tank 301.

[0026] In this embodiment, when in use, the principle of combining biomass gasification and medium-deep geothermal heat to produce heat is as follows: biomass raw materials enter the biomass gasification furnace for gasification reaction to produce combustible gas, which enters the boiler for combustion to produce steam 160-180°C, and an absorption heat pump is used to couple the biomass gasification steam and geothermal comprehensive utilization to produce a heat source, which is driven by steam at 160-180°C and enters the absorption heat pump unit. Circulating water is used to extract heat through multiple stages. The high-temperature circulating water first passes through a primary plate exchanger, and the heat source measured exchange temperature is 68°C / 48°C. The exchanged hot water at 45-55°C enters the heat pump. The tail water after the primary heat exchange continues to exchange heat through the plate heat exchanger as the heat source of the heat pump unit. The inlet and outlet water temperatures on the heat source side of the plate heat exchanger are 48°C / 25°C, and the exchanged hot water at 45-22°C enters the absorption heat pump unit as waste hot water. The pump unit integrates the heat of biomass steam and medium-deep geothermal hot water to supply 90℃ high-temperature water for heating, with a return water temperature of 45-50℃. The entire process reduces the cost of biomass heating. This combination of technologies can reduce the heating cost by 50% on the basis of high-temperature heating. By putting the reinforcement sleeve 304 on the upper part of the water tank 301, putting the mounting frame 302 on the lower part of the water tank 301, and installing the mounting block 305 together with the mounting frame 302 through bolts, the water tank 301 can be supported by the support frame 303. In addition, when the water inside the water tank 301 is heated, the heated water temperature can be monitored in real time through the temperature sensor 308. When the water temperature can rise rapidly, the water tank 301 can be unobstructed as a whole. The function of the controller 309 is to control all electrical equipment.

[0027] Embodiment three: Figure 1-9As shown, the inner wall of the closed window 310 is snap-connected with a closed component 5, and the closed component 5 includes a closed plate 501, which is installed on the front surface of the water tank 301 by screws. The rear surface of the closed plate 501 is fixedly connected with a sealed inner plate 502, which is snap-connected between the inner walls of the closed window 310, and the sealed inner plate 502 is used to prevent water inside the water tank 301 from leaking out. Two sliding door handles 503 are fixedly installed on the front surface of the closed plate 501, and the sliding door handles 503 are used to facilitate the disassembly of the closed plate 501.

[0028] In this embodiment, when in use, by inserting the sealing inner plate 502 into the closed window 310, water can be prevented from leaking out of the closed window 310, and the installation between the closing plate 501 and the water tank 301 is achieved by screws, which are firm and prevent the water pressure inside the water tank 301 from rushing the sealing inner plate 502 out of the closed window 310. When disassembling, the closing plate 501 can be pulled out easily by using the door handle 503, wherein the function of the closed window 310 is to facilitate the inspection and maintenance of the internal structure of the water tank 301.

[0029] The method of use and working principle of this device: When in use, by starting the heat pump body 1 and coupling it with the geothermal energy, the geothermal energy provides a relatively low-temperature but stable source of heat energy, and the heat pump body 1 can increase this part of low-temperature heat energy to a higher temperature, thereby meeting the heating demand. The heat transfer pipe 2 plays the role of transporting heat energy, and the heat energy is transferred back to the spiral conveying pipe 601. When the connecting pipe 604 and the soft pipe 605 are connected, each spiral conveying pipe 601 is interconnected, so that heat can be transported inside it. The spiral conveying pipe 601 is inside the water tank 301, so the heat is dissipated inside the water tank 301 to heat the water inside the water tank 301. At this time, the partition plate 409 is in a contracted state. When the heat is not enough to heat When all the water in the hot water tank 301 is filled, the air pump 406 is started. After the air is taken in, the air pump 406 pressurizes the gas and outputs it from the air pipe 405. By electrically connecting the solenoid valve 404 to the controller 309, when the solenoid valve 404 is closed, the air flow enters the inner side of the piston 407, pushing the piston 407 outward, so that the piston 407 drives the sliding rod 408 to pull the partition plate 409 toward the fixed plate 410. When the solenoid valve 404 is opened, the air flow direction inside the connecting pipe 403 changes, and the piston 407 moves in the opposite direction, thereby driving the sliding rod 408 to move the partition plate 409 in the opposite direction until the three sides of the partition plate 409 are in close contact with the inner wall of the water tank 301, and the sealing ring 415 can completely separate the water tank 301 from the outside. There are two areas, and only the water in one area is heated. The heating speed is accelerated by reducing the amount of heated water. At this time, the slot 414 clamps the soft pipe 605. After the soft pipe 605 is clamped, the heat is concentrated in the spiral conveying pipe 601 in one area, and the remaining heat is slowly discharged from the other spiral conveying pipe 601. When in use, the principle of combining biomass gasification and medium-deep geothermal heat to produce heat is as follows: biomass raw materials enter the biomass gasification furnace for gasification reaction to produce combustible gas, which enters the boiler for combustion to produce steam 160-180℃, and uses an absorption heat pump to couple the biomass gasification steam and geothermal comprehensive utilization to generate a heat source, which is driven by steam at 160-180℃ and enters the absorption heat pump unit, and uses circulating water to heat the heat After multi-stage extraction, the high-temperature circulating water first passes through the first-stage plate exchanger, and the heat source measured exchange temperature is 68℃ / 48℃. The exchanged hot water at 45-55℃ enters the heat pump. The tail water after the first-stage heat exchange continues to exchange heat through the plate heat exchanger as the heat source of the heat pump unit. The inlet and outlet water temperatures on the heat source side of the plate heat exchanger are 48℃ / 25℃, and the exchanged hot water at 45-22℃ enters the absorption heat pump unit as waste hot water. The heat pump unit integrates biomass steam and medium-deep geothermal hot water heat to supply 90℃ high-temperature water for heating, and the return water temperature is 45-50℃. The entire process reduces the biomass heating cost. The combination of this technology can achieve a 50% reduction in heating costs on the basis of high-temperature heating. By putting the reinforcing sleeve 304 on the upper part of the water storage tank 301,The mounting frame 302 is placed on the lower part of the water tank 301, and the mounting block 305 is installed with the mounting frame 302 by bolts. The water tank 301 can be supported by the support frame 303. In addition, when the water inside the water tank 301 is heated, the temperature of the heated water can be monitored in real time by the temperature sensor 308. When the water temperature can be quickly increased, the water tank 301 can be kept unobstructed as a whole. The controller 309 controls all electrical equipment. When in use, the sealing inner plate 502 is inserted into the closed window 310 to prevent water from leaking out of the closed window 310. The installation between the closed plate 501 and the water tank 301 is achieved by screws, which is firm and prevents the water pressure inside the water tank 301 from flushing the sealed inner plate 502 out of the closed window 310.
