Description

Technical Field

[0001] The present application relates to the technical field of water production, and in particular to a water production degassing device. Background Art

[0002] Industrial water comes from a variety of sources, including surface water, groundwater, recycled water, or specialized industrial water treatment systems. These water sources often contain various dissolved gases, such as oxygen, carbon dioxide, and nitrogen. The presence of these dissolved gases can adversely affect industrial production, necessitating degassing during use.

[0003] Thermal degassing is the most common degassing method currently used. This method utilizes the fact that the solubility of gases in water decreases with increasing temperature, and heats the raw water to release dissolved gases. However, thermal degassing consumes a lot of energy and can easily cause water evaporation and the formation of scale. Utility Model Content

[0004] The purpose of this application is to provide a water production and degassing device to improve the water production and degassing effect.

[0005] A water production degassing device provided in the present application adopts the following technical solution: it includes a box body, at least one degassing barrel fixedly installed in the box body, a movable barrel sleeved in the degassing barrel, a lifting mechanism installed in the box body, and several sealing platforms that can be set on the lifting mechanism. The two ends of the movable barrel are through-connected, and a first channel connected to the interior of the degassing passage is provided in the box body. The movable barrel is moved in the degassing barrel through the lifting mechanism. When the sealing platform blocks the degassing barrel, the degassing barrel, the movable barrel and the sealing platform enclose a degassing chamber, and a heating module is installed in the degassing barrel.

[0006] By adopting the above technical solution, the degassing chamber is at its smallest size when the device first starts operating. At this point, the sealing table blocks the degassing barrel, and the movable barrel is positioned lower, forming a relatively small degassing chamber together with the degassing barrel and the sealing table. The lifting mechanism causes the movable barrel to begin moving upward. During this process, the volume of the degassing chamber gradually increases. Because the volume of the degassing chamber is inversely proportional to the pressure, the pressure within the degassing chamber gradually decreases as the volume increases. The provision of the sealing table ensures the sealing of the degassing chamber, preventing gas leakage and ensuring the reliability of the degassing process. Furthermore, the presence of the heating module further improves degassing efficiency and enhances the degassing performance of the device.

[0007] Optionally, the lifting mechanism includes a plurality of polished rods fixedly connected to the box body, a driving platform slidably connected to the polished rods, a top cover fixedly connected to the ends of the polished rods, at least one screw rod, and a first motor connected to the input end of the screw rod. The screw rod is arranged between the top cover and the box body, and the output end of the screw rod is fixedly connected to the driving platform, so that the driving platform moves along the direction of the polished rod.

[0008] With this technical solution, when the first motor operates, its power is transmitted through the lead screw. The lead screw converts rotational motion into linear motion, propelling the drive platform along the direction of the polished rod. Thanks to the guiding action of the polished rod, the drive platform's movement direction is stable and precise. The lead screw's high precision enables precise control of the drive platform's position, meeting various lifting requirements.

[0009] Optionally, the sealing platform is fixedly connected to the driving platform, a sealing ring is fixedly connected to the surface of the sealing platform, the driving platform is fixedly connected to a water inlet pipe, the water inlet pipe passes through the sealing platform, and the sealing platform is provided with an exhaust pipe.

[0010] With the above technical solution, a sealing material is fixedly attached to the surface of the sealing table, primarily ensuring the tightness of the degassing chamber. When the sealing table blocks the degassing barrel, the sealing material fits tightly against the opening of the barrel, preventing gas leakage and ensuring that the degassing process occurs in a relatively closed environment. This improves degassing efficiency and ensures that gases in the produced water are fully released. The delivery pipeline transports the produced water to be degassed to the sealing table, where it then enters the degassing chamber through the water inlet channel. This design ensures smooth entry of the produced water into the degassing device for degassing, ensuring the continuity of the degassing process. The sealing table is equipped with an exhaust pipe, primarily responsible for discharging gases released from the produced water out of the degassing chamber during the degassing process. As the degassing process progresses, gases in the produced water continuously release and accumulate in the degassing chamber. The exhaust pipe allows these gases to be promptly discharged, preventing excessive pressure in the degassing chamber from compromising degassing efficiency. The exhaust pipe can also be connected to subsequent gas processing equipment for further treatment or recycling of the exhausted gases.

[0011] Optionally, the movable barrel is fixedly connected to the bottom end of the driving platform.

[0012] By adopting this technical solution, the movable barrel is fixedly connected to the bottom end of the driving platform. This connection method allows the movable barrel to move synchronously with the movement of the driving platform. Because the driving platform can move up and down along the polished rod under the action of the lifting mechanism, the movable barrel can also be raised and lowered within the degassing barrel accordingly.

[0013] Optionally, the movable barrel is separated from the driving platform, and when the lifting mechanism drives the driving platform to move downward, the sealing platform blocks the end of the movable barrel.

[0014] The above-mentioned technical solution allows the degasser to be separated from the drive platform, providing greater operational flexibility. If the degasser needs to be operated or maintained separately, this separation allows the degasser to be easily removed from the drive platform for inspection, cleaning, or replacement.

[0015] Optionally, the inner wall of the end of the movable barrel is provided with a snap-fit ​​groove, which is arranged along the closed loop inside the movable barrel. The sealing platform is provided with a plurality of snap-fit ​​blocks, and the driving platform is provided with a locking mechanism for driving the snap-fit ​​blocks to move. When the sealing platform blocks the end of the movable barrel, the snap-fit ​​block is snapped with the snap-fit ​​groove under the action of the locking mechanism.

[0016] By adopting this technical solution, the locking mechanism can accurately push the engaging block into the engaging groove when sealing is required, achieving a tight connection between the sealing platform and the movable barrel. At the same time, when the sealing platform and the movable barrel need to be separated, the locking mechanism can also withdraw the engaging block from the engaging groove, allowing the sealing platform to be smoothly removed from the end of the movable barrel. When the engaging block is engaged with the engaging groove, the lifting of the driving platform can drive the movable barrel to move.

[0017] Optionally, the locking mechanism includes a locking plate rotatably connected to the sealing platform, the locking plate is provided with a plurality of movable grooves, the locking plate is fixedly connected to a worm gear, the driving platform is rotatably connected to a worm for driving the turbine to rotate, the driving platform is provided with a second motor for driving the worm to rotate, the sealing platform is provided with a plurality of slide grooves, and the clamping blocks are slidably connected to the slide grooves and the movable grooves respectively.

[0018] By adopting the above technical solution, when locking is required, the second motor starts, driving the worm to rotate. The worm drives the worm wheel to rotate, which in turn rotates the locking disk. As the locking disk rotates, the position of the movable groove changes. Since the engaging block is slidably connected to both the sliding groove and the movable groove, the engaging block moves along the sliding groove under the push of the movable groove, gradually extending and engaging with the engaging groove on the inner wall of the end of the movable barrel, achieving a tight connection between the sealing platform and the movable barrel. When unlocking is required, the second motor is reversed, the locking disk rotates in the opposite direction, and the movable groove pushes the engaging block in the opposite direction, causing it to withdraw from the engaging groove, thereby releasing the connection between the sealing platform and the movable barrel.

[0019] Optionally, the box body is respectively equipped with a cold water inlet and a cold water outlet.

[0020] With the above technical solution, cold water enters the tank through the cold water inlet. This cold water can come from an external cold water supply system, such as a cooling tower, cooling water tank, or chiller. The cold water inlet is typically located appropriately within the tank to evenly distribute the cold water to the areas requiring cooling. The cold water entering the tank exchanges heat with the degassed, high-temperature produced water. This water absorbs the heat from the produced water, gradually lowering its temperature.

[0021] Optionally, a movable seal is provided between the movable barrel and the degassing barrel.

[0022] By adopting the above technical solution, the seal between the mobile and degassing barrels in the water degassing device is crucial. A good seal prevents gas from leaking through the gap between the mobile and degassing barrels during the degassing process, thereby ensuring the tightness of the degassing chamber and improving the degassing effect. If the seal is not tight, external air may enter the degassing chamber, affecting degassing efficiency and even causing degassing failure.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The degassing chamber volume is increased through the lifting mechanism, reducing the pressure inside the chamber. Under low-pressure conditions, the solubility of gas in the produced water is significantly reduced, making it easier for gas to precipitate from the produced water. The heating module in the degassing barrel performs thermal degassing, raising the produced water temperature and further reducing the solubility of gas in the produced water. The combination of reducing pressure and increasing temperature creates a dual effect that promotes faster gas escape, greatly enhancing the degassing effect.

[0025] 2. Good sealing performance: The movable seal between the mobile barrel and the degassing barrel, as well as the sealing material of the sealing table, prevent gas leakage and ensure that the degassing process is carried out in a relatively closed environment. This not only improves the degassing efficiency, but also ensures the reliability and stability of the degassing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0033] The embodiment of the present application discloses a water production and degassing device.

[0034] Example 1, with reference to Figure 1 and Figure 2A water production degassing device includes a box body 1, a degassing barrel 2 fixedly installed in the box body 1, a movable barrel 3 sleeved in the degassing barrel 2, a lifting mechanism 4 installed in the box body 1, and a sealing platform 8 that can be set on the lifting mechanism 4. The degassing barrel 2 of Example 1 is a cylindrical barrel with an open end, and can also be a hollow square barrel. The movable barrel 3 of Example 1 is a hollow cylindrical barrel for example, and can also be a hollow square barrel. The movable barrel 3 can be moved in the degassing barrel 2; the sealing platform 8 can seal the end of the movable barrel 3 under the drive of the lifting mechanism, and can drive the movable barrel 3 to move. The movable barrel 3 and the degassing barrel 2 are movably sealed, and the sealing platform 8 is also provided with an exhaust pipe 46. A heating module 6 is installed in the movable barrel 3. The heating module 6 adopts the most commonly used resistance wire heating, and can also be electromagnetic heating. The inner wall of the movable barrel 3, the inner wall of the degassing barrel 2, and the sealing platform 8 can enclose a sealed degassing chamber 7. In the degassing chamber 7, the heating module 6 heats the produced water, so that the gas dissolved in the water is precipitated. While heating, the lifting mechanism 4 drives the movable barrel 3 to move, increasing the volume of the degassing chamber 7, so that the air pressure in the degassing chamber 7 drops, and the effect of gas precipitation is enhanced. When the movable barrel 3 moves to one end of the degassing barrel 2, the movable barrel 3 stays for a period of time, waiting for the gas to precipitate. The precipitation of gas from the produced water will increase the air pressure in the degassing chamber 7. When the air pressure in the degassing chamber 7 exceeds the atmospheric pressure, the lifting mechanism 4 drives the movable barrel 3 to move downward and opens the exhaust pipe 46, and the precipitated gas is discharged. When the movable barrel 3 moves to the lowest end, the exhaust pipe 46 is closed. The above-mentioned moving process of the movable barrel 3 is repeated, so that the gas can be better precipitated. A first pipe 11 connected to the degassing barrel 2 is provided in the box 1. The box 1 is respectively equipped with a cold water inlet 12 and a cold water outlet 13 of an external chiller. When the degassing of the produced water is completed, the chiller injects cold water into the box 1 for cooling. The first pipe 11 is opened so that the produced water after degassing is transported away.

[0035] refer to Figure 2 The lifting mechanism 4 includes four polished rods 41 fixedly connected to the box body 1, and a driving platform 43 slidably connected to the polished rods 41. The sealing platform 8 is fixedly connected to the bottom end of the driving platform 43. The driving platform 43 is equipped with a water inlet pipe 47. The water inlet pipe 47 passes through the sealing platform 8 and extends into the degassing chamber 7. When the water inlet pipe 47 is opened, the produced water is transported to the degassing chamber 7 through the water inlet pipe 47. The end of the polished rod 41 is fixedly connected to the top cover 45. Two screw rods 42 are provided between the top cover 45 and the box body 1. The output end of the screw rod 42 is fixedly connected to the driving platform 43. The top cover 45 is provided with a first motor 44 connected to the input end of the screw rod 42.

[0036] refer to Figure 3 and Figure 4The sealing platform 8 is fixedly connected to a sealing ring 81, which is made of rubber material, and can also be made of other elastic materials such as silicone, latex, etc. The movable barrel 3 is provided with a snap-in groove 31, which is arranged in a closed loop along the inner wall of the movable barrel 3. The sealing platform 8 is provided with a plurality of slide grooves 53, and the slide grooves 53 are slidably connected to the snap-in blocks 52. The sealing platform 8 is rotatably connected to a lock disk 51, and the end surface of the lock disk 51 is provided with a plurality of movable grooves 54. One end of the snap-in block 52 extends into the movable groove 54, and the movable groove 54 is not parallel to the slide groove 53; a worm gear 55 is fixedly connected to one side of the lock disk 51, and a worm gear meshing with the worm gear 55 is provided in the driving platform 43. Rod 56, the driving platform 43 is provided with a second motor 57 for driving the worm 56 to rotate. As the locking disk 51 rotates, the position of the movable groove 54 changes. Since the clamping block 52 is slidingly connected with the slide groove 53 and the movable groove 54 at the same time, under the push of the movable groove 54, the clamping block 52 moves along the slide groove 53, gradually extends out and clamps with the clamping groove 31 on the inner wall of the end of the movable barrel 3, realizing a tight connection between the sealing platform 8 and the movable barrel 3, so that the lifting mechanism 4 drives the movable barrel 3 to move.

[0037] The operating principle of the water degassing device in this embodiment is as follows: First, during the degassing preparation phase, the device primarily comprises a housing 1, a degassing barrel 2, a movable barrel 3, a lifting mechanism 4, and a sealing platform 8. During initial startup, the movable barrel 3 is positioned lower within the degassing barrel 2. The sealing platform 8 blocks the end of the movable barrel 3, forming a relatively small degassing chamber 7. A movable seal is provided between the movable barrel 3 and the degassing barrel 2 to prevent gas leakage.

[0038] Next, the heating and pressure regulation phase begins. The heating module 6 within the movable barrel 3 begins operating, heating the produced water using methods such as resistance wire heating or electromagnetic heating. This heating reduces the solubility of gases in the produced water, promoting gas evolution. Simultaneously, the lifting mechanism 4 moves the movable barrel 3 upward, increasing the volume of the degassing chamber 7. According to the ideal gas state equation, this increased volume causes the pressure within the degassing chamber 7 to decrease, further enhancing the gas evolution effect.

[0039] Next, the gas release and waiting phase begins. When the mobile barrel 3 reaches one end of the degassing barrel 2, it remains stationary for a period of time. During this period, gas from the produced water continues to release, gradually increasing the pressure within the degassing chamber 7. When the pressure exceeds atmospheric pressure, this indicates that gas release has reached a certain level.

[0040] Next, the exhaust phase begins. The lifting mechanism 4 drives the movable barrel 3 downward, simultaneously opening the exhaust pipe 46 on the sealing table 8. At this point, the released gas is forced out of the degassing chamber 7 under pressure. As the movable barrel 3 moves downward, the pressure within the degassing chamber 7 gradually decreases, and the gas continues to be exhausted until the movable barrel 3 reaches its lowest point. The reciprocating movement of the movable barrel 3 and the opening and closing of the exhaust pipe 46 allow the gas in the produced water to be released more effectively, improving the degassing effect.

[0041] Finally, during the cooling and water discharge phase, after the degassing of the produced water is complete, an external chiller injects cold water into the housing 1. The cold water enters through the cold water inlet 12 on the housing 1, exchanging heat with the high-temperature, degassed produced water, lowering its temperature. The cooled produced water is then transported through a first pipe 11 connected to the degassing drum 2.

[0042] Example 2, reference Figure 5 The difference between this embodiment and embodiment 1 is that the clamping block 52 and the sealing platform 8 are discarded, the movable barrel 3 is welded to the bottom end of the driving platform 43, and the water inlet channel and the exhaust pipe 46 are respectively connected to the movable barrel 3. Compared with embodiment 1, the structure is simpler.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
