Description

Technical Field

[0001] The utility model belongs to the technical field of post-treatment of geothermal deep well water extraction, and in particular relates to a geothermal deep well water extraction purification device. Background Art

[0002] Geothermal resources are clean, environmentally friendly, and renewable energy sources stored deep underground. Due to the diverse distribution of underground mineral deposits, groundwater contains various substances such as combustible gases and sand. At the same time, under mechanical action, hot water easily forms steam. The separation, discharge or application of combustible gases is related to the safe utilization of geothermal resources, and water vapor mixing also causes low heat exchange effects.

[0003] During the operation of geothermal well water extraction systems, sand and associated gas (natural gas) are often present. During system operation, natural gas must be removed before entering the machine room, otherwise there is a risk of explosion. Existing geothermal well water extraction systems use activated carbon adsorption boxes to adsorb natural gas in groundwater, which has the following defects: the activated carbon in the existing activated carbon adsorption boxes is inconvenient to replace and often needs to be disassembled after shutdown, which is cumbersome to operate and affects the continuous purification of groundwater. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a geothermal deep well water purification device, and the technical solution adopted is as follows:

[0005] A geothermal deep well water purification device comprises a box body, both ends of the box body are provided with water inlet and outlet connection ports for connecting other pipes, a partition is provided in the box body for dividing the inner cavity of the box body into two parts, two openings for connecting the inner cavities of the two parts of the box body are provided in the middle position of the partition, and a connecting pipe is installed at the opening position of the partition respectively, a mounting frame is placed inside the connecting pipe, a blocking plate is provided at the bottom of the mounting frame, a top plate is provided at the bottom of the mounting frame, a plurality of mounting frames are arranged in sequence up and down in the middle of the mounting frame, and an adsorption plate is mounted inside the mounting frame;

[0006] A base frame is arranged below the box body, and two pairs of mounting seats for mounting hydraulic cylinders are oppositely mounted above the base frame and on both sides of the box body, and the upper ends of the hydraulic cylinders are respectively connected to the lower surface of the top plate.

[0007] Furthermore, side flow holes are provided on both sides of the mounting frame and below the top plate. When the mounting frame is placed in the connecting pipe, the side flow holes are located above the connecting pipe, so that groundwater can pass through the flow measuring holes, enter the connecting pipe from different directions, pass through the multi-layer adsorption plates, and the groundwater purified by adsorption by the adsorption plates flows out from a connecting port at one end of the box.

[0008] Furthermore, two through holes are opened in the middle of the box body, a gas collecting pipe is installed above the through holes, and a nanomembrane for separating gas is arranged at the connection between the through holes and the gas collecting pipe, which can allow gas to pass through while blocking liquid, thereby separating and collecting natural gas in groundwater.

[0009] Furthermore, the partition adopts an inclined "Z"-shaped structure, with a horizontal plate in the middle that is parallel to the upper and lower surfaces of the box body.

[0010] Furthermore, the installation frame is composed of two adjacent "mouth"-shaped frames, the spacing between the upper and lower frames is equal to the thickness of the adsorption plate, and the adsorption plate is an activated carbon plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The natural gas in the groundwater can be collected and discharged through the gas collecting pipe. A nano-membrane is set at the connection between the gas collecting pipe and the box, which can separate the natural gas while blocking the groundwater from entering the gas collecting pipe, reduce the working pressure of the adsorption plate, and combine with the adsorption plate to improve the separation efficiency of the natural gas.

[0013] The mounting frame in the utility model can be lifted by a hydraulic cylinder. After being lifted, the blocking plate below the mounting frame will block the connecting pipe at the corresponding position, and the adsorption plate located at the bottom of the mounting frame will also be exposed from the box body, so that the adsorption plate in the mounting frame can be replaced and repaired, and the corresponding connecting pipe is blocked in the process. Since two connecting pipes are used, when the adsorption plate in a certain mounting frame is replaced and repaired, the continuous operation of the purification device is not affected.

[0022] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0023] As attached Figure 1-6 shown.

[0024] A geothermal deep well water purification device comprises a box body 1. Both ends of the box body 1 are provided with water inlet and outlet connection ports for connecting other pipelines. A partition plate 3 is provided inside the box body 1 for dividing the inner cavity of the box body into two parts. The partition plate 3 adopts a "Z"-shaped structure inclined at 90 degrees, and a horizontal plate parallel to the upper and lower surfaces of the box body 1 is in the middle.

[0025] Two openings for communicating the inner cavities of the two parts of the box are provided in the horizontal plate in the middle position of the partition 3, and a connecting pipe 4 is respectively installed at the position of the opening in the partition 3, and a mounting frame 5 is placed inside the connecting pipe 4, and a blocking plate 51 is provided at the bottom of the mounting frame 5, and a top plate 6 is provided at the bottom of the mounting frame 5, and a plurality of mounting frames 52 are arranged in sequence in the upper and lower parts of the middle part of the mounting frame 5, and the mounting frame 52 is composed of two layers of adjacent "mouth"-shaped frames, and an adsorption plate 53 is clamped between the upper and lower frames, and the adsorption plate 53 can be disassembled and assembled by pushing and pulling.

[0026] A base frame 2 is provided below the box body 1 , and two pairs of mounting seats 8 for mounting hydraulic cylinders 7 are installed above the base frame 2 and on opposite sides of the box body 1 , and the upper ends of the hydraulic cylinders 7 are connected to the lower surfaces of the top plates 6 , respectively.

[0027] Two through holes are provided in the middle of the box body 1 , a gas collecting pipe 9 is installed above the through holes, and a nano-membrane 91 for separating gas is provided at the connection between the through holes and the gas collecting pipe 9 .

[0028] When in use, the device is installed in the geothermal deep well water pipeline. After the groundwater enters the box body 1, it needs to flow through the connecting pipe 4. When the groundwater flows through the connecting pipe 4, the adsorption plate 53 located inside the mounting frame 5 in the connecting pipe 4 can adsorb the natural gas in the groundwater. The purified groundwater enters the next operation through another connecting port in the box body 1.

[0029] While groundwater flows through the inside of the box 1, the natural gas in the groundwater can also be collected and discharged through the gas collecting pipe 9. A nanomembrane 91 is set at the connection between the gas collecting pipe 9 and the box 1, which can separate the natural gas while blocking the groundwater from entering the gas collecting pipe 9, thereby reducing the working pressure of the adsorption plate 53.

[0030] After being used for a period of time, the mounting frame 5 at the corresponding position can be lifted by the hydraulic cylinder 7. After being lifted, the blocking plate 51 below the mounting frame 5 will block the connecting pipe 4 at the corresponding position, and the adsorption plate 53 located at the bottom of the mounting frame 5 will also be exposed from the box body 1, so that the adsorption plate 53 in the mounting frame 5 can be replaced and repaired, and the corresponding connecting pipe 4 can be blocked in the process. Since two connecting pipes 4 are used, when the adsorption plate 53 in a certain mounting frame 5 is replaced and repaired, the continuous operation of the purification device is not affected.

[0031] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
