Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology and relates to a two-phase dynamic flash evaporation and concentration device. Background Technology

[0002] In wastewater treatment, wastewater is concentrated through evaporation. This concentrates harmful components such as heavy metals, high concentrations of salt, and organic pollutants, facilitating subsequent targeted treatment. Wastewater concentration is a necessary step in reducing, rendering harmless, and utilizing wastewater as a resource. Flash evaporation is a highly efficient physical process that utilizes the sensible heat of a liquid and causes it to partially vaporize instantaneously through a sudden pressure drop. It is a highly efficient technology for evaporating and concentrating wastewater.

[0003] Traditional wastewater evaporation treatment relies on a heat source to heat the wastewater within the equipment. The heated wastewater evaporates, resulting in concentrated wastewater, but this method has low evaporation efficiency. Patent document CN117326725A discloses a terminal wastewater evaporator and system for power plants. This system includes an evaporation chamber with a water pipe connected through its side. The water pipe outlet is fixedly connected to a water outlet pipe, which is connected to a nozzle. A heating pipe is fitted onto the water outlet pipe, and a feed inlet is fixedly connected to the heating pipe. By spraying wastewater onto the heating pipe, evaporation is facilitated, improving evaporation efficiency.

[0004] However, the evaporation system has the following shortcomings during use: when wastewater falls onto the heating tube, it easily forms a liquid film. When the spray falls onto the heating tube, the spray cannot directly contact the heating tube. Heat needs to pass through the liquid film before it can be transferred to the droplets. It cannot directly contact the heating tube and evaporate quickly as it would when there is no liquid film, which affects the evaporation efficiency.

[0005] To address the above problems, this invention proposes a two-phase dynamic flash evaporation and concentration device. Summary of the Invention

[0008] Furthermore, in the same heat exchange assembly, ropes are fixedly connected between two adjacent heat exchange plates.

[0009] Furthermore, the atomizing assembly includes an atomizing shell and a liquid storage shell; the liquid storage shell is fixedly installed at the upper end of the ring, and a rotating ring is rotatably fitted to the liquid storage shell, the rotating ring being fixedly connected to the inner wall of the tank; an inlet pipe is installed on the tank, one end of the inlet pipe passing through the rotating ring and communicating with the liquid storage shell; the atomizing shell is installed at the upper end of the ring and communicates with the liquid storage shell.

[0010] Furthermore, an exhaust pipe is installed on the upper part of the tank, and the exhaust pipe is connected to a first branch pipe. The lower end of the first branch pipe extends into the tank body, and the portion of the first branch pipe inside the tank body is connected to a jet pipe. A tray is provided inside the tank body, and a bubble head is installed on the tray. The tray is located above the jet pipe.

[0011] Furthermore, an installation ring is slidably installed inside the tank, and an air inlet chamber is provided on the installation ring. The air inlet chamber is connected to a flexible hose, and the flexible hose is connected to the first branch pipe through a second branch pipe. A through hole is provided on the bottom wall of the air inlet chamber. A second drive assembly is provided on the tank to drive the installation ring to move up and down.

[0012] Furthermore, filter screens are installed at both the upper and lower ends of the mounting ring, and multiple spheres are placed on the lower filter screen; The upper surface of the filter screen below is a cone shape with the tip pointing upwards.

[0013] Furthermore, the first drive assembly includes a first motor and a rotating shaft; the rotating shaft is rotatably mounted inside the tank, the first motor is mounted on the tank, and the output shaft of the first motor is fixedly connected to the rotating shaft; the rotating tube and the rotating shaft are connected by a transmission component.

Adjacent heat exchange plates collide with each other, which helps to shake off the residual wastewater on the heat exchange plates. At the same time, the contact between adjacent heat exchange plates squeezes out the residual wastewater, preventing the wastewater from forming a liquid film on the heat exchange plates and affecting the evaporation efficiency, thus ensuring the evaporation efficiency of the heat exchange plates. When the elastic plate moves to the third sliding groove, the heat exchange assembly unfolds again and moves below the atomizing shell. The wastewater sprayed from the atomizing shell falls onto the heat exchange plates, where it is heated and evaporates.

[0018] Water vapor in the exhaust pipe flows into the jet pipe through the first branch pipe and is then sprayed onto the wastewater on the tray for further evaporation, which helps to improve evaporation efficiency.

[0019] Water vapor in the exhaust pipe flows into the mounting ring through the second branch pipe and is blown toward the sphere through the through hole, causing the sphere to roll on the filter screen, which helps to evaporate the wastewater adsorbed on the sphere and improves the evaporation efficiency.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-11 The diagram shows a two-phase dynamic flash evaporation and concentration device.

[0024] Example 1: As Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: A two-phase dynamic flash evaporation and concentration device includes a tank 1, a ring 23 and a heat exchange assembly.

[0025] The ring 23 is rotatably installed inside the tank body 1, and the ring 23 is coaxially arranged with the tank body 1. Specifically, a second sliding groove 30 is provided on the inner wall of the tank body 1, and a second slider 37 is fixedly connected to the ring 23. The second slider 37 is slidably arranged in the second sliding groove 30.

[0026] A rotating tube 27 is rotatably installed inside the tank body 1, and the rotating tube 27 is coaxially arranged with the tank body 1.

[0027] A first drive assembly is installed on the tank body 1 to drive the rotation of the ring 23 and the rotating tube 27. The first drive assembly includes a first motor 2 and a rotating shaft 22. The first motor 2 is fixedly mounted on the tank body 1, and the rotating shaft 22 is rotatably mounted inside the tank body 1, and the rotating shaft 22 is coaxial with the tank body 1. The output shaft of the first motor 2 is fixedly connected to the upper end of the rotating shaft 22. Fixing plates 35 are fixedly connected to both the upper and lower ends of the ring 23. The lower fixing plate 35 is fixedly connected to the lower end of the rotating shaft 22, and the upper fixing plate 35 is rotatably engaged with the rotating tube 27.

[0028] A transmission component is provided between the rotating tube 27 and the rotating shaft 22. The rotating shaft 22 drives the rotating tube 27 to rotate through the transmission component. A clearance groove 16 is provided on the top wall of the tank body 1, and the transmission component is disposed in the clearance groove 16.

[0029] The transmission components include a gear ring 32, a first gear 25, and a second gear 26. A rotating shaft 22 is fixedly connected to a rotating disk 24, and the gear ring 32 is fixedly connected to the rotating disk 24. The second gear 26 is fixedly sleeved on the rotating tube 27, and the first gear 25 is rotatably mounted in the relief groove 16 via a shaft. Both the gear ring 32 and the second gear 26 mesh with the first gear 25.

[0030] When the first motor 2 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the ring 23 to rotate through the fixed plate 35 at the lower end. At the same time, the rotating shaft 22 drives the rotating disk 24 to rotate, and the rotating disk 24 drives the rotating tube 27 to rotate through the gear ring 32, the first gear 25 and the second gear 26, and the rotating tube 27 and the ring 23 rotate in opposite directions.

[0031] Multiple heat exchange components are arranged within the annulus 23. These components are circumferentially distributed along the axis of the annulus 23. Each heat exchange component includes a fixing block 39 and heat exchange plates 28. One end of the fixing block 39 is fixedly connected to the rotating tube 27. The fixing block 39 is fixedly connected to an arc plate 34, which is coaxially arranged with the rotating shaft 22. The heat exchange plates 28 are slidably fitted onto the arc plate 34. Multiple heat exchange plates 28 are connected sequentially by elastic ropes 41. Adjacent heat exchange plates 28 are fixedly connected by ropes 40. A fourth groove 42 is formed on the arc plate 34, and the ropes 40 and elastic ropes 41 are disposed within this groove. Within the same heat exchange component, the fixing block 39 is fixedly connected to adjacent heat exchange plates 28, while heat exchange plates 28 away from the fixing block 39 are fixedly connected to elastic plates 43. A third groove 31 is formed on the inner wall of the ring 23. The elastic sheet 43 is slidably disposed in the third groove 31 and is in frictional contact with the inner wall of the third groove 31. A friction layer is provided on the inner wall of the third groove 31 to increase the frictional resistance to the elastic sheet 43.

[0032] A heating device is installed inside the heat exchange plate 28 to heat the heat exchange plate 28 and cause the wastewater falling on the heat exchange plate 28 to evaporate.

[0033] The ring 23 has a liquid outlet 36, which is located at a position corresponding to the fixed plate 35, that is, between the two fixed plates 35. The third chute 31 is disconnected at the liquid outlet 36.

[0034] When the rotating tube 27 rotates, it drives the fixed block 39 to rotate. Within a heat exchange assembly, the fixed block 39 drives the heat exchange plates 28 fixed to it to rotate. Due to the friction between the elastic plate 43 and the inner wall of the third sliding groove 31, the heat exchange plate 28 at the end furthest from the fixed block 39 remains stationary, causing multiple heat exchange plates 28 to unfold sequentially. When the multiple heat exchange plates 28 are fully unfolded, the fixed block 39 drives them to rotate simultaneously, causing the elastic plate 43 to slide within the third sliding groove 31 against friction. When the fixed block 39 moves to the liquid outlet 36, the elastic plate 43 disengages from the third sliding groove 31 as the fixed block 39 continues to move. Under the action of the elastic rope 41, the multiple heat exchange plates 28 move closer to each other, the heat exchange assembly closes, and adjacent heat exchange plates 28 collide, thus shaking off any residual wastewater on the heat exchange plates 28. When two adjacent heat exchange plates 28 come into contact, the wastewater remaining on the heat exchange plates 28 is squeezed out and sprayed onto the inner wall of the tank 1 through the liquid outlet 36.

[0035] An atomizing assembly is provided at the upper end of the circular ring 23. The atomizing assembly includes an atomizing shell 33 and a liquid storage shell 29. The liquid storage shell 29 is fixedly installed at the upper end of the circular ring 23, and a rotating ring 38 is rotatably fitted to the liquid storage shell 29. The rotating ring 38 is fixedly connected to the inner wall of the tank body 1. A liquid inlet pipe 3 is installed on the tank body 1, and one end of the liquid inlet pipe 3 passes through the rotating ring 38 and communicates with the liquid storage shell 29. The atomizing shell 33 is fixedly installed at the upper end of the circular ring 23, and the atomizing shell 33 communicates with the liquid storage shell 29.

[0036] Wastewater is transported to the storage tank 29 through the inlet pipe 3, and the wastewater in the storage tank 29 is atomized and sprayed out through the atomizing shell 33. The atomized wastewater is sprayed onto the heat exchange plate 28, and the wastewater on the heat exchange plate 28 is heated and evaporated.

[0037] An exhaust pipe 4 is installed at the upper end of the tank 1. The evaporated water vapor rises and is discharged through the exhaust pipe 4. The exhaust pipe 4 is connected to a suction mechanism that creates negative pressure inside the tank 1.

[0038] A tray 18 is fixedly installed inside the tank 1. Multiple bubbling heads 19 are installed on the tray 18. The wastewater that has undergone evaporation treatment falls onto the tray 18.

[0039] The exhaust pipe 4 is connected to a first branch pipe 5, the lower end of which extends into the tank body 1. Multiple jet pipes 17 are fixedly installed on the first branch pipe 5 inside the tank body 1. The jet pipes 17 are located below the tray 18. Water vapor entering the exhaust pipe 4 flows into the jet pipes 17 through the first branch pipe 5. The water vapor ejected from the jet pipes 17 flows through the bubble head 19 into the wastewater on the tray 18, where it is reheated and evaporated.

[0040] A heating layer 20 is embedded in the side wall of the tank 1. The heating layer 20 heats the inner wall of the tank 1, thereby causing the wastewater on the inner wall of the tank 1 to evaporate.

[0041] A drain pipe 44 is installed at the bottom of tank 1. Wastewater that has undergone evaporation and concentration treatment can be discharged through the drain pipe 44.

[0042] Working principle: Wastewater is transported to the storage tank 29 through the inlet pipe 3. The wastewater in the storage tank 29 enters the atomizing shell 33. The wastewater in the atomizing shell 33 is atomized and sprayed onto the heat exchange plate 28 below. The wastewater on the heat exchange plate 28 is heated and evaporated. The water vapor rises and flows into the exhaust pipe 4.

[0043] The first motor 2 is started, and the rotating shaft 22 rotates. The rotating shaft 22 drives the rotating disk 24 to rotate, and the rotating disk 24 drives the rotating tube 27 to rotate via the gear ring 32, the first gear 25, and the second gear 26. The rotating tube 27 drives the fixed block 39 to rotate relative to the ring 23, and the fixed block 39 drives the corresponding heat exchange components to move. Figure 9 As shown, the fixed block 39 rotates clockwise relative to the ring 23.

[0044] In the same heat exchange assembly, the fixed block 39 drives the heat exchange plates 28 fixed to it to move. Due to the friction between the elastic plate 43 and the inner wall of the third sliding groove 31, the heat exchange plates 28 away from the fixed block 39 are resisted. As a result, under the pull of the fixed block 39, multiple heat exchange plates 28 overcome the elastic force of the corresponding elastic ropes 41 and gradually unfold. The opening angle between adjacent heat exchange plates 28 is limited by the ropes 40. This facilitates the smooth unfolding of multiple heat exchange plates 28 and helps to avoid excessive tension on the elastic ropes 41.

[0045] Once the heat exchange assembly is fully deployed, meaning that the adjacent heat exchange plates 28 are at their maximum angle, the heat exchange plates 28 cannot be deployed further. The fixing block 39 pulls multiple heat exchange plates 28 simultaneously via the heat exchange plates 28 and the rope 40. The elastic plate 43 overcomes the friction of the third sliding groove 31 and slides along it. The deployed heat exchange assembly moves towards the atomizing shell 33. When the heat exchange assembly moves below the atomizing shell 33, the atomizing shell 33 sprays atomized wastewater onto the heat exchange plates 28. The wastewater falling onto the heat exchange plates 28 evaporates upon heating.

[0046] When the wastewater remaining after evaporation on the heat exchange plate 28 flows downward along the heat exchange plate 28, it easily forms a liquid film on the heat exchange plate 28. When the wastewater is sprayed onto the heat exchange plate 28 again, it will come into contact with the liquid film instead of directly contacting the heat exchange plate 28, which affects the evaporation efficiency.

[0047] As the rotating tube 27 rotates, the heat exchange assembly continues to move, gradually reaching the liquid outlet 36. When the elastic plate 43 disengages from the third sliding groove 31, under the action of the elastic rope 41, the heat exchange plates 28 move towards the fixed block 39, causing the heat exchange assembly to quickly close. Adjacent heat exchange plates 28 collide, shaking off any residual wastewater. Simultaneously, the contact between adjacent heat exchange plates 28 helps to squeeze out any remaining wastewater, preventing the formation of a liquid film on the heat exchange plates 28. Some of the detached wastewater is sprayed onto the inner wall of the tank 1. The wastewater on the inner wall of the tank 1 evaporates upon heating, further improving the evaporation efficiency.

[0048] As the heat exchange assembly continues to move, the elastic plate 43 moves back into the third slide groove 31. Due to the large frictional force exerted on the elastic plate 43 by the third slide groove 31, the heat exchange plates 28 away from the fixed block 39 remain stationary. As the fixed block 39 moves, the heat exchange assembly gradually unfolds. When the heat exchange assembly is fully unfolded, the fixed block 39 pulls multiple heat exchange plates 28 simultaneously via the heat exchange plates 28 and the rope 40, while the elastic plate 43 slides along the third slide groove 31.

[0049] Therefore, as the heat exchange assembly moves, the atomizing shell 33 sprays wastewater sequentially onto multiple heat exchange plates 28, which helps improve the evaporation effect. When the elastic plate 43 disengages from the third sliding groove 31, the heat exchange assembly closes together, causing the residual wastewater on the heat exchange plates 28 to fall off, preventing the formation of a liquid film on the heat exchange plates 28. Thus, when the heat exchange assembly moves back below the atomizing shell 33, the wastewater sprayed from the atomizing shell 33 falls directly onto the heat exchange plates 28, which helps improve the evaporation efficiency. When the elastic plate 43 contacts the third sliding groove 31, the heat exchange assembly unfolds.

[0050] At the same time, the first motor 2 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the ring 23 to rotate, thereby causing the ring 23 to face different parts inside the tank 1, which is beneficial for the wastewater coming out of the outlet 36 to fall onto different parts of the inner wall of the tank 1, thus improving the evaporation efficiency.

[0051] The evaporated wastewater eventually falls onto tray 18. Part of the water vapor in exhaust pipe 4 flows into jet pipe 17 through the first branch pipe 5, and jet pipe 17 sprays the water vapor upwards. The water vapor sprayed from jet pipe 17 enters the wastewater on tray 18 through bubble head 19, heating the wastewater on tray 18 and further evaporating it, thus improving evaporation efficiency and consequently increasing wastewater concentration efficiency.

[0052] Example 2: This example is an improvement based on Example 1.

[0053] An installation ring 7 is slidably installed inside the tank body 1. A second drive assembly is installed on the tank body 1 to drive the installation ring 7 to slide up and down.

[0054] The second drive assembly includes a second motor 11, a lead screw 10, and a guide rod. Two first sliding grooves 9 are symmetrically formed on the inner wall of the tank 1. A first slider 8 is slidably positioned within each first sliding groove 9, and a mounting ring 7 is fixedly connected between the two first sliders 8. The lead screw 10 is rotatably mounted in one of the first sliding grooves 9 and is threadedly connected to the corresponding first slider 8. The guide rod is fixedly mounted in the other first sliding groove 9 and slides with the corresponding first slider 8. The second motor 11 is mounted on the tank 1, and its output shaft is fixedly connected to one end of the lead screw 10. When the second motor 11 rotates, the lead screw 10 rotates, causing the corresponding first slider 8 to slide along a third sliding groove 31, thereby moving the mounting ring 7 up and down.

[0055] An air inlet chamber 12 is provided at the upper end of the mounting ring 7, and a flexible hose 21 is connected to the upper end of the air inlet chamber 12. A first branch pipe 5 is connected to a second branch pipe 6, which extends into the tank body 1 and is connected to the flexible hose 21. A control valve is installed on the second branch pipe 6. When the control valve is opened, some of the water vapor in the first branch pipe 5 flows through the second branch pipe 6 to the flexible hose 21, and then flows into the air inlet chamber 12. A through hole 13 is provided on the bottom wall of the air inlet chamber 12.

[0056] The mounting ring 7 is lowered into the wastewater on the tray 18, and the water vapor in the air inlet chamber 12 flows into the wastewater through the through hole 13, which helps to accelerate the evaporation of the wastewater on the tray 18.

[0057] The upper and lower ends of the mounting ring 7 are equipped with filter screens 14. The upper end of the lower filter screen 14 is a cone with the tip pointing upwards, and multiple spheres 15 are placed on the lower filter screen 14.

[0058] The second motor 11 is started, causing the mounting ring 7 to move downwards, allowing the mounting ring 7, filter screen 14, and ball 15 to enter the wastewater on the tray 18. The control valve is opened, and some of the water vapor in the first branch pipe 5 flows through the second branch pipe 6 to the hose 21, and then into the air inlet chamber 12. The water vapor in the air inlet chamber 12 flows into the wastewater through the through hole 13, which helps to accelerate the evaporation of the wastewater on the tray 18.

[0059] Next, the mounting ring 7 is moved upwards, causing the mounting ring 7, filter screen 14, and ball 15 to move upwards and be removed from the wastewater. Then, the control valve is opened intermittently. When the control valve is open, water vapor sprayed from the through-hole 13 is directed towards the ball 15, causing the ball 15 to roll upwards along the lower filter screen 14. Simultaneously, water vapor is sprayed onto the ball 15, causing the wastewater adsorbed on the ball 15 to evaporate. When the control valve is closed, the ball 15 rolls downwards along the lower filter screen 14. By intermittently spraying water vapor onto the ball 15, causing the ball 15 to roll on the lower filter screen 14, the evaporation effect of the waste liquid on the ball 15 is improved.

[0060] After the control valve is intermittently opened for a certain period of time, the control valve is closed, causing the mounting ring 7 to move downwards again, so that the mounting ring 7, filter screen 14 and ball 15 fall downwards into the wastewater on the tray 18.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
