Description

Technical Field

[0001] This utility model relates to the field of geothermal water degassing technology, and in particular to a geothermal water degassing device for a geothermal heating system. Background Technology

[0002] Geothermal water is a thermal energy manifestation of energy stored inside the Earth that is carried to the surface through water; it is usually formed by the heating of molten lava or by natural heating with increasing depth.

[0003] In geothermal systems, gas may accumulate at high points in the pipes or at the vent valves, forming air locks. These air locks can hinder the normal circulation of hot water, causing poor water flow in the geothermal system. When the gas in the pipes is removed, the hot water can flow more smoothly, thereby improving the heat exchange efficiency of the geothermal system. Therefore, a geothermal degassing device is needed for geothermal heating systems.

[0004] Chinese Patent Publication No. CN203694676U discloses a geothermal degassing device for a geothermal heating system, including a shell, an exhaust port and a geothermal water inlet on the upper part of the shell, and a geothermal water outlet on the bottom of the shell. Several partitions are vertically fixed to the inner wall of the shell, the partitions are parallel to each other and spaced apart, and water flow channels are formed between the partitions.

[0005] The above-mentioned patents still have the following shortcomings in practice:

[0006] The aforementioned patent utilizes a deep geothermal well submersible pump to deliver geothermal water to a geothermal degassing device. The degassed geothermal water is then sent to a heat exchanger for heat exchange, and the heat-exchanged geothermal water is reinjected into the geothermal reinjection well. While this method can achieve the purpose of degassing geothermal water and then utilizing the removed gas, it cannot treat the gas generated by the geothermal water. The presence of impurities in the geothermal water can contaminate the heat exchanger and reduce the integrity of the device. Utility Model Content

[0007] The main purpose of this utility model is to provide a geothermal degassing device for a geothermal heating system, which can effectively solve the problem that the gas removed from the geothermal water cannot be filtered and reused when collecting geothermal water.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A geothermal degassing device for a geothermal heating system includes a degassing box, with support legs fixedly connected to the four corners of the lower end of the degassing box. A stirring and separating device is installed inside the degassing box, and an exhaust device is installed at the rear of the upper end of the degassing box. A water inlet is fixedly connected to the upper middle side of the right end of the degassing box, and a regulating valve is fixedly connected to the upper right side of the outer surface of the water inlet.

[0011] Preferably, the toothed ring and the toothed rack mesh with each other.

[0012] Preferably, the three elastic sheets are respectively engaged in the tooth groove of the toothed ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This device, through its designed regulating valve, can control the flow rate of geothermal water entering the degassing tank. By controlling the flow rate of geothermal water entering the degassing tank, it can ensure that the exhaust device has sufficient time to fully degas the hot water. This helps to improve degassing efficiency, ensures that the gas in the hot water is effectively removed, and thus improves the overall performance of the geothermal system.

[0018] 2. This device, through its designed exhaust system, can not only degas the geothermal water but also filter the gas.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 and Figure 2As shown, a geothermal degassing device for a geothermal heating system includes a degassing box 1. Support legs 4 are fixedly connected to the four corners of the lower end of the degassing box 1. A stirring and separating device 6 is installed inside the degassing box 1. An exhaust device 5 is installed at the rear of the upper end of the degassing box 1. A water inlet 2 is fixedly connected to the upper middle side of the right end of the degassing box 1. A regulating valve device 3 is fixedly connected to the upper right side of the outer surface of the water inlet 2. A water outlet 7 is fixedly connected to the lower left side of the degassing box 1.

[0030] Before implementation, the inlet 2 and outlet 7 of this device need to be connected to the geothermal water pipe so that the device and the geothermal water pipe are integrated.

[0031] In the above-mentioned process, activated carbon filter cotton must be placed in the exhaust device 5 before implementing the device.

[0032] In the above-mentioned process, after the device is connected to the geothermal water pipe, the geothermal water enters the inlet 2. The flow rate of the geothermal water into the degassing tank 1 is controlled by the rotary regulating valve device 3. Then, the exhaust device 5 and the stirring and separating device 6 are activated simultaneously. The stirring and separating device 6 can slow down the flow rate of the geothermal water and stir it, breaking the air bubbles in the geothermal water and causing the hot air to float upward. Then, the geothermal water flows out from the outlet 7. The exhaust device 5 will extract the hot air from the geothermal water in the degassing tank 1 and filter it, so that the geothermal hot air becomes a usable resource before being discharged. The utilization method is as follows: a heat exchanger is installed at the outlet of the exhaust device 5 to make full use of the geothermal hot air and reduce resource consumption.

[0033] Furthermore, in order to achieve the purpose of controlling the flow rate of geothermal water entering the degassing tank 1 by the torsion regulating valve device 3, refer to... Figure 3 and Figure 4 The regulating valve device 3 includes a fixed housing 31 and a sealing valve 34. The fixed housing 31 is fixedly connected to the upper right side of the outer surface of the water inlet 2. The front end and the middle of the rear end of the fixed housing 31 are rotatably connected to a torsion valve 36. A spur gear 35 is fixedly connected to the front of the outer surface of the torsion valve 36. Three elastic plates 37 are fixedly connected in an annular array at the front edge of the outer surface of the torsion valve 36. A toothed ring 32 is fixedly connected to the left side of the front wall of the fixed housing 31. The sealing valve 34 is slidably connected to the right side of the inner cavity of the water inlet 2. A rack 33 is fixedly connected to the upper part of the outer surface of the sealing valve 34.

[0034] The toothed ring 32 and the toothed rack 33 mesh with each other;

[0035] The three elastic plates 37 are respectively engaged in the tooth grooves of the toothed ring 32.

[0036] In the above scenario, if the regulating valve device 3 is opened, the sealing valve 34 will block the geothermal water, causing the geothermal water to remain inside the sealing valve 34. At this time, the torsion valve 36 needs to be twisted vigorously, causing the torsion valve 36 to drive the spur gear 35 to rotate clockwise. The spur gear 35, through its meshing relationship with the sealing valve 34, drives the rack 33 to move forward. When the rack 33 moves forward, it will drive the sealing valve 34 to continue moving forward together. Then, the geothermal water will flow out from several rectangular holes at the front of the sealing valve 34 and flow into the left side of the inlet 2, and then flow into the degassing box 1 from the inlet 2 in sequence.

[0037] As described above, when the torsion valve 36 rotates, it will drive the elastic plate 37 to rotate as well. Under the action of the toothed ring 32 and the elastic plate 37, the torsion valve 36 will have resistance when it rotates, thereby ensuring that the geothermal water will not push the sealing valve 34 forward.

[0038] Furthermore, in order to achieve the purpose of the stirring and separating device 6 in continuing to slow down the flow of geothermal water and breaking up the air bubbles inside the geothermal water, refer to... Figure 5 and Figure 6 The stirring and separating device 6 includes a stepper motor 64 and two partitions 61. The stepper motor 64 is fixedly connected to the middle of the upper end of the degassing box 1. A drive rod 63 is fixedly connected to the output end of the stepper motor 64. Stirring rods 62 are fixedly connected to the upper, middle and lower left and right sides of the outer surface of the drive rod 63, respectively. The two partitions 61 are fixedly connected to the middle and lower sides of the four walls of the degassing box 1, respectively. The drive rod 63 is rotatably connected to the two partitions 61, respectively.

[0039] In the above process, the stepper motor 64 is started to rotate. When the stepper motor 64 rotates, it drives the drive rod 63 to continue rotating through the coupling. The drive rod 63 then transmits power to the stirring rod 62, causing the stirring rod 62 to rotate as well. The outer surface of the stirring rod 62 has several protrusions, which cause the stirring rod 62 to break up the air bubbles inside the geothermal water, allowing the hot air to quickly leave the geothermal water.

[0040] In the above, the partition 61 has several circular holes, so that when the geothermal water enters the partition 61 from the inlet 2, the geothermal water continues to be slowed down by the partition 61, increasing the time the geothermal water stays in the degassing box 1, so that the hot air inside the geothermal water can be better sucked out of the degassing box 1 by the exhaust device 5.

[0041] Furthermore, in order to achieve the purpose of the exhaust device 5 drawing geothermal hot air from the degassing box 1 and then filtering it, so that the geothermal water can be turned into a usable resource, refer to... Figure 7 and Figure 8The exhaust device 5 includes a placement chamber 52 and an air pump 51. The placement chamber 52 is fixedly connected to the middle of the upper rear part of the degassing box 1. The middle of the left and right ends of the placement chamber 52 are both fixedly connected to the suction pipes 53. The placement chamber 52 is slidably connected to the filter chamber 54 inside. The air pump 51 is fixedly connected to the middle of the upper rear part of the degassing box 1.

[0042] The input end of the air pump 51 is connected to the air outlet of the placement chamber 52, and the air inlets of the two suction pipes 53 are fixedly connected to the upper left and right sides of the degassing box 1, respectively.

[0043] In the above, activated carbon filter cotton is placed inside filter chamber 54.

[0044] In the above process, the air pump 51 is turned on to operate, so that the air pump 51 draws the hot water and hot air from the degassing box 1 into the placement chamber 52 through the air suction pipe 53. Then, the hot air is filtered through the activated carbon filter cotton placed in the filter chamber 54. After filtration, the hot air enters the air pump 51 and then exits from the air outlet of the air pump 51.

[0045] As described above, the filter chamber 54 can be removed from the placement chamber 52, making it convenient to replace the activated carbon filter cotton placed inside.

[0046] In the above, the heat exchanger needs to be installed at the air outlet of the air pump 51 so that the geothermal hot air can be turned into a usable resource.

[0047] It should be noted that the specific installation method, circuit connection method, and control method of the air pump 51 and stepper motor 64 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
