Description

Technical Field

[0001] This application relates to the field of reverse forced circulation evaporation production technology, and in particular to a reverse forced circulation evaporator device. Background Technology

[0002] Currently, with the continuous development of science and technology and the widespread application of hydrometallurgical technology, environmental protection requirements are becoming increasingly stringent. The application of evaporation and concentration technology is becoming more widespread, the composition of evaporation media is becoming more complex, and the scaling of evaporator heater bundles is becoming more complex, making scale prevention and inhibition increasingly challenging. Traditional forced circulation evaporators are no longer sufficient for the evaporation of high-concentration, polycrystalline materials. Crystallization in the evaporator heater bundles is severe, significantly shortening the cleaning cycle and resulting in unsatisfactory evaporator lifespan. Exploring new scale prevention and inhibition methods is imperative.

[0003] Existing technologies offer numerous measures for preventing and inhibiting scale buildup, such as electromagnetic scale inhibition, ultrasonic scale inhibition, and chemical scale inhibition. However, these present significant challenges for evaporator heater bundles. Because evaporators operate at high temperatures, electromagnetic scale inhibition coils struggle to withstand these temperatures. Furthermore, the tube-and-shell structure of the evaporator heater bundle makes installing ultrasonic devices difficult. Adding chemical scale inhibitors can lead to product contamination and other problems. This explains the lack of significant breakthroughs in forced circulation evaporation technology over the years.

[0004] Therefore, there is an urgent need for an evaporator device that improves the ease of scale inhibition in evaporators, in light of the aforementioned technologies. Summary of the Invention

[0005] To improve the continuity and efficiency of scale inhibition in evaporators, this application provides a reverse forced circulation evaporator device.

[0006] This application provides a reverse forced circulation evaporator device, which adopts the following technical solution: A reverse forced circulation evaporator device includes an evaporator device body, which includes a separation chamber, a heater, a reflux pipe, a forced circulation pump, and a separation component. The separation chamber and the heater are both vertically arranged, with the separation chamber located directly above the heater. The separation component is located between the separation chamber and the heater, with its upper end connected to the separation chamber and its lower end connected to the heater. An inlet pipe is connected to the outside of the heater, and an outlet pipe is connected to the upper end of the separation chamber. A balance pipe and a water outlet pipe are also connected to the outside of the heater. Both the balance pipe and the water outlet pipe are equipped with a first valve. The balance pipe is located between the inlet pipe and the water outlet pipe. The reflux pipe is located between the heater and the separation chamber, with one end connected to the lower end of the heater and the other end connected to the separation chamber. The forced circulation pump is located at the lower end of the heater and is connected to the reflux pipe.

[0007] By adopting the above technical solution, steam enters the heater through the steam inlet pipe, and condensate is formed through heat exchange, then discharged through the water outlet pipe. Due to the complex composition of the evaporation medium, scale easily forms on the inner wall of the heater during the heating process. The steam moves upward and is discharged through the steam outlet pipe. When descaling is required, the first valve of the balance pipe is opened, and the liquid enters the heater through the balance pipe and moves downward. Since the medium flow direction of this device is downward, the downward flow of the liquid creates a downward scouring force on the scale on the inner wall of the heater, thereby washing the scale off the inner wall of the heater. The liquid and scale enter the return pipe together, and the forced circulation pump transports the liquid and scale to the separation chamber. The separation component discharges the scale, and the liquid passes through the separation component and continues to scour the inner wall of the heater. When the treatment is completed, the first valve on the water outlet pipe is opened, and the liquid is discharged from the water outlet pipe, improving the continuity and efficiency of evaporator descaling.

[0008] Optionally, an expansion joint connecting pipe is provided between the separation chamber and the heater, with the upper end of the expansion joint connecting pipe connected to the separation chamber and the lower end of the expansion joint connecting pipe connected to the heater.

[0009] By adopting the above technical solution, the expansion joint connecting pipe helps reduce the probability of damage to the connection between the separation component and the heater caused by thermal expansion stress, and improves the stability of the evaporator descaling process.

[0010] Optionally, the separation assembly includes an isolation ring plate, a guide plate, a discharge pipe, and a second valve. The isolation ring plate is located inside the separation chamber, and its lower end is fixedly connected to the lower end of the separation chamber. The inner diameter of the isolation ring plate gradually decreases from top to bottom. The guide plate is fixedly connected inside the isolation ring plate and has several water inlets vertically. The discharge pipe is connected to the separation chamber and is directly opposite the lower end of the isolation ring plate. The second valve is connected to the end of the discharge pipe away from the isolation ring plate.

[0011] By adopting the above technical solution, the liquid and scale in the return pipe are centrifugally separated in the separation chamber. The scale is thrown to the edge of the separation chamber by centrifugal force. Separated by the isolation ring plate, the scale is located between the isolation ring plate and the separation chamber and stored inside the discharge pipe. The second valve blocks the discharge pipe, and the liquid will pass through the water inlet on the guide plate and return to the heater to continue to flush the inner wall of the heater, which improves the continuity and efficiency of evaporator descaling.

[0012] Optionally, the reflux pipe is tangentially connected to the separation chamber. When the mixture flows into the separation chamber from the reflux pipe, the liquid-solid (scale) separation is achieved by using centrifugal force, and the solid (scale) is discharged through the discharge pipe.

[0013] By adopting the above technical solution, when the liquid and scale separate from the return pipe, the liquid and scale move in an arc. Due to the tangential setting of the return pipe, under centrifugal force, the scale can just fall into the inside of the discharge pipe, which helps to reduce the probability of scale adhering to the guide plate and improves the convenience of scale cleaning.

[0014] Optionally, a conical block is fixed inside the heater, located at the upper end of the heater, with the largest cross-sectional area of ​​the conical block located at the bottom, and a gap is left between the lower end of the conical block and the inner wall of the heater.

[0015] By adopting the above technical solution, the heater supports the conical block, and the conical block guides the liquid falling from the expansion joint connecting pipe, allowing the liquid to fall along the inner wall of the heater, thus enabling the liquid to better descale the heater and improving the utilization rate of the liquid.

[0016] Optionally, a retaining ring plate is fixed inside the separation chamber. The retaining ring plate is located above the reflux pipe and is an inverted conical ring. The retaining ring plate has several through holes. A cleaning device for cleaning the retaining ring plate is provided inside the separation chamber. The cleaning device is located below the retaining ring plate. An observation eyepiece is provided outside the separation chamber.

[0017] By adopting the above technical solution, when liquid and scale drip onto the upper end of the guide plate, the fine scale will remain on the guide plate and inside the water inlet. The steam in the heater moves upward through the water inlet, thereby driving the fine scale upward. The intercepting ring plate intercepts the scale and the liquid rising along the wall. The steam continues to move upward through the through hole, and the liquid flows back into the separation chamber. The observation eyepiece is used to observe the internal situation during separation. The cleaning component cleans the scale on the intercepting ring plate, allowing the steam to smoothly move upward through the through hole, further improving the convenience of scale removal.

[0018] Optionally, the cleaning components include a sliding rod, a return spring, a vibrating plate, a moving plate, a motor, a rotating shaft, and a lever. The sliding rod is located above the intercepting ring plate, with its lower end passing through the intercepting ring plate and slidingly connected to it vertically. The return spring is located at the upper end of the intercepting ring plate and between the sliding rod and the intercepting ring plate. In its natural state, the return spring causes the sliding rod to move upward. The vibrating plate is fixedly connected to the outside of the sliding rod and abuts against the lower end of the intercepting ring plate. The moving plate is fixedly connected to the lower end of the sliding rod and is perpendicular to the sliding rod. The motor is fixedly connected to the outside of the separation chamber, with its output shaft passing through the separation chamber and coaxially fixedly connected to the rotating shaft. The rotating shaft is located below the intercepting ring plate. The lever is fixedly connected to the side of the rotating shaft away from the motor and is located on one side of the moving plate along its length.

[0019] By adopting the above technical solution, the separation chamber supports the motor. The motor and the rotating shaft work together to drive the lever to rotate. During the rotation of the lever, it comes into contact with the moving plate, causing the moving plate to move downward. As the moving plate moves downward, it drives the vibrating plate and the sliding rod to move downward. As the sliding rod moves downward, it squeezes the return spring. When the lever separates from the moving plate, the return spring drives the sliding rod to move upward. The sliding rod drives the vibrating plate to move upward and knocks on the intercepting ring plate, thereby causing the scale attached to the intercepting ring plate to fall off, improving the convenience of cleaning the scale on the intercepting ring plate.

[0020] Optionally, a mist separator is provided in the separation chamber, and the mist separator is located above the sliding rod.

[0021] By adopting the above technical solution, the mist separator performs secondary purification of steam, realizes vapor-liquid separation, and improves the quality of the recovered products.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Steam enters the heater shell side through the steam inlet pipe, and condensation occurs through heat exchange, which is then discharged through the outlet pipe. Due to the complex composition of the evaporation medium, scale easily forms on the inner wall of the heater during the heat exchange and heating process. Because this device is designed with the medium flowing downwards, the downward movement of the liquid creates a downward scouring force on the scale on the heater's inner wall, thus washing the scale off. The liquid and scale then enter the return pipe together, where a forced circulation pump transports the liquid and scale to the separation chamber. The separation component discharges the scale, while the liquid passes through the separation component and continues to scour the inner wall of the heater, improving the ease of descaling the evaporator. 2. The liquid and scale in the return pipe enter the separation chamber and are separated under the action of centrifugal force. The liquid is located on the inner and outer sides of the isolation ring plate. The liquid is located in the middle of the separation chamber and inside the isolation ring plate. The scale is separated under the action of centrifugal force and is located on the inner wall of the separation chamber and the outer side of the isolation ring plate. The scale is discharged in time through the discharge pipe, while the liquid is continuously circulated in the system for heating and evaporation, which improves the evaporation efficiency of the steam generator. 3. The separation chamber supports the motor. The motor and the rotating shaft work together to drive the lever to rotate. During the rotation of the lever, it comes into contact with the moving plate, causing the moving plate to move downward. As the moving plate moves downward, it drives the vibrating plate and the sliding rod to move downward. As the sliding rod moves downward, it compresses the return spring. When the lever separates from the moving plate, the return spring drives the sliding rod to move upward. The sliding rod drives the vibrating plate to move upward and knocks on the trapping ring plate, thereby causing the scale attached to the trapping ring plate to fall off, improving the convenience of cleaning the scale on the trapping ring plate.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses a reverse forced circulation evaporator device.

[0029] Reference Figure 1 A reverse forced circulation evaporator device includes an evaporator device body 1. The evaporator device body 1 includes a separation chamber 11, a heater 12, a return pipe 13, a forced circulation pump 14, and a separation component 2. The heater 12 is connected to a steam inlet pipe 121 on the outside. Steam enters the shell side of the heater 12 through the steam inlet pipe 121 to carry out a heat exchange process. Due to the complex composition of the medium in contact with the inner wall of the heater 12, scale is easily formed on the inner wall of the heater 12 during the heating process.

[0030] Reference Figure 1Both the separation chamber 11 and the heater 12 are vertically arranged, with the separation chamber 11 located directly above the heater 12. The separation assembly 2 is located between the separation chamber 11 and the heater 12, with its upper end connected to the separation chamber 11 and its lower end connected to the heater 12. The upper end of the separation chamber 11 is connected to a steam outlet pipe 111. The heater 12 is also connected to a balance pipe 122 and a water outlet pipe 123. Both the balance pipe 122 and the water outlet pipe 123 are equipped with a first valve 124. The balance pipe 122 is located between the steam inlet pipe 121 and the water outlet pipe 123. The return pipe 13 is located between the heater 12 and the separation chamber 11, with one end connected to the lower end of the heater 12 and the other end connected to the separation chamber 11. The forced circulation pump 14 is located at the lower end of the heater 12 and is connected to the return pipe 13. Steam moves upward and is discharged through steam outlet pipe 111. When descaling is required, the first valve 124 of balance pipe 122 is opened, and liquid enters the heater 12 through balance pipe 122 and moves downward. When the liquid moves downward, it creates a scouring force on the scale on the inner wall of heater 12, thereby flushing the scale off the inner wall of heater 12. The liquid and scale enter the return pipe 13 together, and the forced circulation pump 14 transports the liquid and scale to the separation chamber 11. Through the action of centrifugal force, the scale is thrown to the edge of separation chamber 11, and separation component 2 discharges the scale. The liquid passes through separation component 2 and returns to heater 12 to continue to flush the inner wall of heater 12. When the treatment is completed, the first valve 124 on water outlet pipe 123 is opened, and the liquid is discharged from water outlet pipe 123, which improves the continuity and efficiency of evaporator descaling.

[0031] Reference Figure 1 An expansion joint connecting pipe 15 is provided between the separation chamber 11 and the heater 12. The upper end of the expansion joint connecting pipe 15 is connected to the separation chamber 11, and the lower end of the expansion joint connecting pipe 15 is connected to the heater 12. The expansion joint connecting pipe 15 helps to reduce the probability of thermal expansion stress causing damage to the connection between the separation component 2 and the heater 12.

[0032] Reference Figure 1 and Figure 2 The separation assembly 2 includes an isolation ring plate 21, a guide plate 22, a discharge pipe 23, and a second valve 24. The isolation ring plate 21 is located inside the separation chamber 11, and the lower end of the isolation ring plate 21 is fixedly connected to the lower end of the separation chamber 11. The inner diameter of the isolation ring plate 21 gradually decreases from top to bottom. The liquid and scale in the return pipe 13 undergo centrifugal separation through the separation chamber 11, throwing the scale towards the edge of the separation chamber 11. Under the separation of the isolation ring plate 21, the scale falls between the isolation ring plate 21 and the separation chamber 11, while the liquid is located inside the isolation ring plate 21. The liquid flows back to the heater 12 through the water inlet 25 on the guide plate 22.

[0033] Reference Figure 2The discharge pipe 23 is connected to the separation chamber 11 and is directly opposite the lower end of the isolation ring plate 21. The second valve 24 is connected to the end of the discharge pipe 23 away from the isolation ring plate 21. The scale is stored in the discharge pipe 23. The second valve 24 blocks the discharge pipe 23, so that the scale is stored inside the discharge pipe 23.

[0034] Reference Figure 1 and Figure 2 The return pipe 13 is tangentially set to the separation chamber 11. When the liquid and scale separate from the return pipe 13, the liquid and scale separate under the action of centrifugal force. Since the return pipe 13 is tangentially set, the scale falls between the isolation ring plate 21 and the separation chamber 11, which helps to reduce the probability of scale adhering to the guide plate 22 and improves the convenience of scale cleaning.

[0035] Reference Figure 2 A conical block 16 is fixed inside the heater 12. The conical block 16 is located at the upper end of the heater 12, with the largest cross-sectional area of ​​the conical block 16 located at the bottom. A gap is left between the lower end of the conical block 16 and the inner wall of the heater 12. The heater 12 supports the conical block 16, and the conical block 16 guides the liquid falling from the expansion joint connecting pipe 15, allowing the liquid to fall along the inner wall of the heater 12, so that the liquid can better perform descaling operation on the heater 12 and improve the utilization rate of the liquid.

[0036] Reference Figure 2 Inside the separation chamber 11, there is a retaining ring plate 17. The retaining ring plate 17 is located above the return pipe 13 and is an inverted conical ring. The retaining ring plate 17 has several through holes 171. An observation eyepiece 18 is provided on the outside of the separation chamber 11. When liquid and scale drip onto the upper end of the guide plate 22, the fine scale will stay on the guide plate 22 and inside the water inlet 25. The steam in the heater 12 moves upward through the water inlet 25, thereby driving the fine scale upward. The retaining ring plate 17 intercepts the scale and returns the liquid to the inside of the separation chamber 11. The steam continues to move upward through the through holes 171. The observation eyepiece 18 is used to observe the internal situation during separation.

[0037] Reference Figure 2 and Figure 3The separation chamber 11 is equipped with a cleaning component 3 for cleaning the intercepting ring plate 17. The cleaning component 3 is located below the intercepting ring plate 17 and cleans the scale on the intercepting ring plate 17, allowing steam to pass smoothly through the through hole 171 and move upward. The cleaning component 3 includes a sliding rod 31, a return spring 32, a vibrating plate 33, a moving plate 34, a motor 35, a rotating shaft 36, and a lever 37. The sliding rod 31 is located above the intercepting ring plate 17, and its lower end passes through the intercepting ring plate 17 and is slidably connected to the intercepting ring plate 17 vertically. The return spring 32 is located at the upper end of the intercepting ring plate 17 and is located between the sliding rod 31 and the intercepting ring plate 17. The intercepting ring plate 17 and the return spring 32 cooperate to support the sliding rod 31. In its natural state, the return spring 32 causes the sliding rod 31 to move upward.

[0038] Reference Figure 3 The vibrating plate 33 is fixedly connected to the outside of the sliding rod 31 and abuts against the lower end of the intercepting ring plate 17. The moving plate 34 is fixedly connected to the lower end of the sliding rod 31 and is set perpendicular to the sliding rod 31. The motor 35 is fixedly connected to the outside of the separation chamber 11. The output shaft of the motor 35 passes through the separation chamber 11 and is coaxially fixedly connected to the rotating shaft 36. The rotating shaft 36 is located below the intercepting ring plate 17. The lever 37 is fixedly connected to the side of the rotating shaft 36 away from the motor 35. The lever 37 is located on the side of the moving plate 34 along its length. The separation chamber 11 supports the motor 35. 5 and the rotating shaft 36 work together to drive the lever 37 to rotate. During the rotation of the lever 37, it comes into contact with the moving plate 34. The lever 37 causes the moving plate 34 to move downward. During the downward movement of the moving plate 34, it drives the vibrating plate 33 and the sliding rod 31 to move downward. During the downward movement of the sliding rod 31, it squeezes the return spring 32. When the lever 37 separates from the moving plate 34, the return spring 32 drives the sliding rod 31 to move upward. The sliding rod 31 drives the vibrating plate 33 to move upward and knocks on the intercepting ring plate 17, thereby causing the scale attached to the intercepting ring plate 17 to fall off.

[0039] Reference Figure 2 The separation chamber 11 is equipped with a mist separator 19, which is located above the sliding rod 31. The mist separator 19 performs secondary purification of the steam, realizes gas-liquid separation, and improves the quality of the recovered product.

[0040] The implementation principle of the reverse forced circulation evaporator device in this application embodiment is as follows: Steam enters the heater 12 through the steam inlet pipe 121 and undergoes a heat exchange process. Due to the complex composition of the evaporation medium, scale is formed on the inner wall of the heater 12 during contact with it. The steam in the separation chamber 11 moves upward and is discharged through the steam outlet pipe 111. Since the medium flow direction of this device is downward, the downward flow of the liquid creates a scouring force on the scale on the inner wall of the heater 12, thereby flushing the scale off the inner wall of the heater 12. The liquid and scale enter the return pipe 13 together. The forced circulation pump 14 transports the liquid and scale to the separation chamber 11. The scale is located between the isolation ring plate 21 and the separation chamber 11. The liquid re-enters the circulation through the water inlet 25, and the scale is discharged in time through the discharge pipe 23, thereby improving the descaling efficiency of the evaporator.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
