Description

Technical Field

[0001] The present invention relates to the technical field of geothermal resource development, and more particularly to a geothermal water impurity removal device based on geothermal water exploration and collection. Background Art

[0002] Geothermal energy is an ideal clean energy source with rich energy reserves and no greenhouse gas emissions during use, causing no harm to the earth's environment. Currently, the utilization of geothermal energy mainly lies in fields such as geothermal power generation and geothermal heating using geothermal water. Since there are many impurities in geothermal water, if it is directly collected and utilized without impurity removal, it is likely to cause blockage of the heat exchanger, resulting in a decrease in the heat exchange efficiency of the heat exchanger and even affecting the service life of the heat exchanger. Therefore, during the process of collecting geothermal water, it is necessary to use an impurity removal device to perform impurity removal treatment before the geothermal water enters the heat exchanger.

[0003] After the impurity removal device intercepts a large amount of impurities, it is necessary to discharge the impurities. Currently, when discharging the impurities, the valve of the water inlet pipe needs to be closed, and the impurity removal operation of the geothermal water needs to be aborted during the process of discharging the impurities, resulting in a decrease in the overall collection efficiency of the geothermal water.

DETAILED DESCRIPTION OF THE INVENTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Components of the embodiments of the present invention usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0020] Embodiment The following is a further description with reference to Figures 1 - 5 As shown, in combination with specific embodiments, this embodiment provides a geothermal water impurity removal device for geothermal water exploration and collection, including a housing 1. A water inlet pipe 11 is arranged at the top of the housing 1, and a water outlet pipe 12 is arranged at the bottom of the housing. Geothermal water enters the housing 1 from the water inlet pipe 11, and after impurity removal treatment, it is discharged from the water outlet pipe 12. A partition plate 2 is arranged vertically in the middle of the housing 1. The partition plate 2 divides the interior of the housing 1 into two chambers. A plurality of overflow plates 3 are distributed along the height direction of the housing 1 on both sides of the partition plate 2. Flow guiding plates 21 are arranged between the overflow plates 3 on the upper and lower sides of the partition plate 2. An inverted V-shaped intercepting plate 4 is arranged above the partition plate 2. The intercepting plate 4 includes a central part 41 and turning parts 42 rotatably arranged on both sides of the central part 41. A distribution mechanism 5 is arranged above the intercepting plate 4.

[0021] In the initial state, the distribution mechanism 5 centrally distributes the geothermal water entering from the water inlet pipe 11 to one of the turning parts 42. The turning part 42 can intercept impurities with larger particle sizes in the geothermal water. Then, the geothermal water continues to flow into the uppermost overflow plate 3. The overflow plate 3 can make the impurities in the geothermal water precipitate at the bottom. The geothermal water reaching the top of the overflow plate 3 flows out onto the flow guiding plate 21 and is guided by the flow guiding plate 21 to the next overflow plate 3. After multiple overflow effects, the geothermal water flows out from the lowermost overflow plate 3. When it is necessary to discharge the impurities intercepted on the turning part 42 and the impurities precipitated on the overflow plate 3, by making the distribution mechanism 5 distribute the geothermal water into the turning part 42 on the other side, the turning part 42 and the overflow plate 3 can be prevented from continuing to receive water. At this time, the geothermal water can continue to be purified in the turning part 42 and the overflow plate 3 on the other side. Therefore, the collection process of the geothermal water will not be interrupted.

[0022] With reference to Figure 1 、 Figure 2As shown in the figure, a fine filter element 7 is further arranged inside the housing 1. The fine filter element 7 includes a frame body 71 and a filter membrane 72 embedded in the frame body 71. Installation grooves 14 are formed on both sides of the housing 1, and the installation grooves 14 are located below the lowest overflow plate 3. The two side edges of the frame body 71 are respectively inserted into the installation grooves 14, and the water outlet pipe 12 is located below the center position of the filter membrane 72. When the geothermal water passes through multiple overflow plates 3 in sequence, the filter membrane 72 can further intercept the particulate impurities remaining in the geothermal water, so that the impurities in the geothermal water are removed more thoroughly before being discharged from the water outlet pipe 12, and the geothermal water is not likely to cause blockage to the heat exchange equipment.

[0023] Refer to Figure 2 As shown in the figure, slag discharge cavities 6 are arranged on both sides of the bottom of the housing 1. Through openings 13 communicating with the slag discharge cavities 6 are formed on one side of each overflow plate 3 on the housing 1. A closing plate 61 for simultaneously closing the multiple through openings 13 is arranged in the slag discharge cavities 6. The closing plate 61 is slidably arranged in the slag discharge cavities 6 along the height direction of the slag discharge cavities 6 and is fixedly connected to the top of the slag discharge cavities 6 through bolts 62. Inserting the closing plate 61 into the slag discharge cavities 6 to close the through openings 13 can prevent the geothermal water from flowing into the slag discharge cavities 6 during the impurity removal process; when it is necessary to discharge the impurities after the impurity removal process on one side is completed, pulling the closing plate 61 upward to make the through openings 13 communicate with the slag discharge cavities 6 can discharge the impurities deposited on the multiple overflow plates 3 and the remaining geothermal water from the housing 1 into the slag discharge cavities 6 together.

[0024] Refer to Figure 3 As shown in the figure, the distribution mechanism 5 includes a distribution groove 51 and a rotating member 52 for driving the distribution groove 51 to rotate. Traction members 53 for driving the flipping portions 42 to flip are arranged on both sides of the bottom of the distribution groove 51. When the distribution groove 51 rotates to one side, the lowest end of the distribution groove 51 drives the flipping portion 42 to rotate upward to fit against the side wall of the housing 1 through the traction member 53. After the distribution groove 51 discharges the geothermal water from the lowest end, the flipping portion 42 located below the lowest end of the distribution groove 51 can intercept the large particle impurities in the geothermal water; at the same time, the highest end of the distribution groove 51 leaves the traction member 53 on the other side, and the flipping portion 42 on the other side will no longer be under traction and will flip downward to separate from the side wall of the housing 1, and then the flipping portion 42 collides with the uppermost overflow plate 3 to facilitate pouring the intercepted impurities into the overflow plate 3.

[0025] Refer to Figure 4As shown, the rotating member 52 includes a rotating motor 521, a worm gear 522, and a worm 523. Two support blocks 524 are provided on the outer wall of the housing 1. The worm 523 is rotatably connected between the two support blocks 524. The distribution groove 51 is rotatably connected in the housing 1 through a rotating shaft 511. The worm gear 522 is connected to one end of the rotating shaft 511 extending outside the housing 1 and meshes with the worm 523. The rotating motor 521 is fixedly arranged on one of the support blocks 524 and can drive the worm 523 to rotate. Starting the rotating motor 521 drives the worm 523 to rotate. The worm gear 522 rotates synchronously under the meshing action of the worm 523 and drives the distribution groove 51 to rotate to a specified state through the rotating shaft 511, so as to guide the geothermal water entering from the water inlet pipe 11 to any side inside the box body, while the other side inside the box body can facilitate the impurity discharge operation.

[0026] Referring to Figure 3 , Figure 4 As shown, the traction member 53 includes a traction rope 531, a support shaft 532, and a rotating frame 533. The rotating frame 533 is rotatably connected to the side wall of the housing 1. The support shaft 532 is fixedly installed in the housing 1 and is located above the rotating frame 533. The traction rope 531 is slung on the support shaft 532. One end of the traction rope 531 is fixedly connected to one end of the rotating frame 533 away from the side wall of the housing 1, and the other end of the traction rope 531 is fixedly connected to one end of the flipping part 42 away from the central part 41. A spring piece 534 is connected between the rotating frame 533 and the side wall of the housing 1. When the rotating frame 533 rotates downward to an inclined state, the spring piece 534 can deform and has a tendency to drive the rotating frame 533 to rotate upward. When the distribution groove 51 rotates to one side, the lowest end of the distribution groove 51 applies a pressing force to the rotating frame 533 below and causes the rotating frame 533 to flip downward. The traction rope 531 applies a pulling force to the flipping part 42 under the traction of the rotating frame 533 and makes the end of the flipping part 42 abut against the side wall of the housing 1. At the same time, the highest end of the distribution groove 51 is separated from the rotating frame 533 on the other side. The rotating frame 533 on the other side returns to the horizontal state under the elastic force of the spring piece 534, and the traction rope 531 no longer applies a pulling force to the flipping part 42 on the other side. Therefore, the flipping part 42 on the other side rotates downward under its own gravity and collides with the overflow plate 3 at the top, and the intercepted impurities enter the lowest end of the overflow plate 3 under the action of their own weight and the residual accumulated water in the overflow plate 3.

[0027] It should be noted that the towing rope 531 is an elastic rope that can undergo elastic deformation and change its own length. When the rotating frame 533 is in an inclined state, the towing rope 531 is in a taut state to ensure that a pulling force can be applied to the flipping part 42 and the end of the flipping part 42 is pressed against the side wall of the housing 1. When the rotating frame 533 rotates to the horizontal state, due to the elasticity of the towing rope 531 and the ability of its length to change, the flipping part 42 can collide with the overflow plate 3 multiple times to ensure that all the intercepted impurities flow onto the uppermost overflow plate 3.

[0028] Referring Figure 3 As shown, the central part 41 includes a central column 411 which is welded to the top end of the partition plate 2. Flexible connecting strips 412 are provided on both sides of the central column 411. The flipping part 42 includes a flat section 421 and a mesh plate section 422. The flat section 421 is fixedly connected to the flexible connecting strip 412, and the mesh plate section 422 is provided at the end of the flat section 421 away from the flexible connecting strip 412. After the geothermal water enters the flat section 421, it will flow towards the mesh plate section 422. The mesh plate section 422 can intercept impurities and allow the geothermal water to enter the overflow plate 3. Through the flexible connecting strip 412, the flipping part 42 can rotate, and at the same time, there will be no gap at the connecting part to affect the interception effect of impurities.

[0029] Referring Figure 2 、 Figure 5 As shown, the overflow plate 3 includes an L-shaped plate 31 and an inclined plate 32. The L-shaped plate 31 includes a horizontal part 311 and a vertical part 312. The horizontal part 311 is fixedly connected to the side wall of the housing 1, and the vertical part 312 is provided at the end of the horizontal part 311 away from the side wall of the housing 1. The inclined plate 32 is provided at the top of the vertical part 312 and extends obliquely upward towards the center of the housing 1. When the geothermal water flows to the overflow plate 3, it will flow into the space formed between the L-shaped plate 31 and the side wall of the housing 1 along the inclined plate 32. As the water level continuously rises, the geothermal water exceeding the highest end of the inclined plate 32 will flow out first, and during this process, the precipitating impurities in the geothermal water will sink onto the horizontal part 311 of the L-shaped plate 31. An activated carbon adsorption block 22 is provided on the guide plate 21. One side of the activated carbon adsorption block 22 is in contact with the partition plate 2, and the other side is in contact with the end face of the inclined plate 32 away from the vertical part 312. The geothermal water overflowing from the inclined plate 32 will enter the activated carbon adsorption block 22, and the activated carbon adsorption block can adsorb impurities such as particulate matter, ionic substances, and dissolved gases in the geothermal water, thereby further improving the impurity removal effect of the geothermal water.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
