Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and specifically to a high flash stripping tower. Background Technology

[0002] The working principle of a high-pressure flash stripper is mainly based on the stripping process, which recovers the absorbed solute and separates the absorbent from the solute to achieve regeneration.

[0003] In the prior art, patent document CN110156103B discloses a novel stripping tower, which also discloses a vertical cylindrical tower body with a tower cover. The tower cover is equipped with a stripping steam pipe and a motor. The output shaft of the motor is connected to the tower plate shaft through a coupling. Multiple tower plates are installed on the tower plate shaft. The tower plate includes multiple blades evenly distributed along the circumference. The blades are provided with multiple through holes. The tower body is also equipped with a steam input pipe, a liquid inlet pipe, a liquid outlet located at the bottom of the tower body, and a sewage pipe equipped with a water pump. The tower plates of each adjacent two layers are staggered along the circumference.

[0004] In practical applications, after steam is fed into the stripping tower, it flows vertically upward along the holes on the tower plate. However, because the steam input pipe in the existing technology is located on one side of the tower body, the steam only flows upward on the side closest to the steam input pipe after being fed in. Therefore, when sewage drips from the side away from the steam input pipe, the probability of it exchanging heat with the steam is reduced, which in turn affects the sewage treatment effect. Summary of the Invention

[0005] The purpose of this invention is to provide a high flash stripping tower to solve the following technical problems:

[0006] After the steam is introduced, it only flows upward on the side closest to the steam inlet pipe. Therefore, when sewage drips from the side furthest from the steam inlet pipe, the probability of it exchanging heat with the steam is reduced.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A high flash stripping tower includes a tower body; several sets of steam output terminals are arranged in a circumferential array in the tower body, and each steam output terminal is connected to a steam input module for outputting steam into the tower body.

[0009] The top of the tower is equipped with a spray module for spraying the wastewater to be treated into the tower. A stripping steam pipe is also provided on one side of the top of the tower for discharging the stripped organic matter.

[0010] Each of the steam output terminals is rotatably arranged in the tower body, and in the initial state, the output port of the steam output terminal faces the direction of the steam input module;

[0011] Each of the steam output terminals is connected to a rotating module that drives its reciprocating rotation.

One side of the storage chamber is connected to a sewage input pipe for inputting sewage to be treated into the storage chamber. The spray module includes a spray plate arranged at the top of the tower body. Several sets of spray plates are arranged in a circumferential array on the outer edge of the spray plate. Both the spray plates and the spray plate have liquid delivery chambers. Several sets of nozzles communicating with the liquid delivery chambers are evenly arranged at the bottom of each spray plate. A liquid delivery pipe is rotatably arranged at the top of the tower body. One end of the liquid delivery pipe is connected to the spray plate, and the other end is connected to the storage chamber through a return pipe.

[0013] The return pipe is equipped with a pump body.

[0014] Preferably, the tower body is further provided with a conical guide plate, the outer edge of which is fixed to the inner wall of the tower body;

[0015] The bottom of the tower body is provided with a liquid storage tank, and the liquid storage tank has a liquid storage trough. The bottom of the conical guide plate is connected to the liquid storage trough through a conduit.

[0016] Preferably, one end of the infusion tube is rotatably connected to the return tube, and the other end is fixed to the spray plate;

[0017] The infusion tube has a first gear fixedly mounted on its top outer side, and a servo motor fixedly mounted on the top of the tower body. The output end of the servo motor is fixed to a second gear, and the second gear meshes with the first gear.

[0018] Preferably, each of the spray plates has a support rod fixedly installed at its bottom, and several sets of tower plates are fixedly installed at intervals along the vertical direction on each support rod, with several sets of through holes evenly opened on the tower plates.

[0019] Preferably, the steam input module includes an annular pipe arranged in the tower body, and each steam output end is connected to the annular pipe through a branch pipe. The steam input module also includes a rectangular pipe arranged on the outside of the tower body, and the outside of the rectangular pipe is connected to the main steam pipeline.

[0020] The inner side of the rectangular tube is connected to the annular tube through several sets of steam input pipes.

[0021] Preferably, both ends of each steam output end are fixed to baffles, the two side baffles are rotatably connected to supports fixedly arranged on the annular pipe via support shafts, and a third gear is fixedly arranged between the two side baffles, the third gear being coaxial with the two side support shafts;

[0022] Among them, a rack that meshes with the third gear is slidably arranged between the supports on both sides, and the rack is connected to the push part that drives it to slide back and forth on the annular tube.

[0023] Preferably, the pushing part includes an annular frame arranged on the outside of the annular tube. The annular frame is coaxially arranged with the annular tube and fixed to the support rod. Several sets of arc-shaped protrusions are fixedly arranged in a circumferential array on the side of the annular frame facing the axis. Two sets of adjacent arc-shaped protrusions are supported by an arc-shaped groove. A positioning frame is fixedly arranged at one end of the rack facing the annular frame. A guide wheel is rotatably arranged at the end of the positioning frame away from the rack. The guide wheel is used to roll and abut against the arc-shaped protrusions and the arc-shaped groove. The other end of the rack is connected to an elastic mechanism arranged on the annular tube.

[0024] Preferably, the elastic mechanism includes a guide rod fixedly arranged on the inner surface of the annular tube, an L-shaped bracket fixed to the rack slidably arranged on the guide rod, and a telescopic spring provided on the guide rod.

[0025] The beneficial effects of this invention are:

[0026] (1) When treating sewage, the present invention sprays the sewage to be treated into the tower body through the spray module. At the same time, the steam input module synchronously inputs steam into the tower body through the steam output end. The steam can flow upward from the output port of the steam output end. At this time, the sewage exchanges heat with the steam during the dripping process, vaporizing the organic matter in the sewage. Finally, the organic matter in the sewage is discharged through the stripping steam pipe. The present invention sets up a rotating module to synchronously drive each steam output end to reciprocate in the tower body to adjust the output angle of the steam from the steam output end, thereby expanding the output range of the steam in the tower body. This ensures that there is rising steam at each position in the tower body, effectively avoiding the phenomenon that heat exchange cannot be generated when the sewage drips in a direction away from the steam output end. In addition, each steam output end is arranged circumferentially, so that setting a small number of steam output ends can meet the heat exchange requirements and save costs.

[0027] (2) The present invention can drive the second gear to rotate by a servo motor. The second gear drives the infusion pipe to rotate by meshing with the first gear. The infusion pipe drives each spray plate to rotate in the tower body synchronously through the spray plate, thereby improving the spray range of each nozzle. At the same time, the sewage can be dispersed into fine particles under the action of centrifugal force, thereby improving the subsequent heat exchange efficiency.

[0028] (3) The present invention does not require the use of other servo drive devices to drive the steam output end to rotate. It can drive the steam output end to rotate back and forth at the same time as driving the spray plate to rotate, which can save costs, improve the stability of its rotation, and achieve the effect of synchronous operation.

Detailed Implementation

[0036] 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.

[0037] Example 1

[0038] Please see Figure 1 As shown, the present invention is a high flash stripping tower, including a tower body 1; specifically, in this embodiment, the tower body 1 is a cylindrical vertical structure. The specific model and size of the tower body 1 are not limited, as long as they meet the actual sewage treatment effect.

[0039] Please see Figures 2-4Several sets of steam output terminals 501 are arranged in a circumferential array in the tower body 1. Each steam output terminal 501 is connected to a steam input module to output steam into the tower body 1. Specifically, this embodiment does not limit the specific number of steam output terminals 501. For example, eight sets of steam output terminals 501 are arranged in this embodiment.

[0040] The top of the tower body 1 is equipped with a spray module for spraying the wastewater to be treated into the tower body 1. The top side of the tower body 1 is also equipped with a stripping steam pipe 102 for discharging the stripped organic matter.

[0041] Each steam output terminal 501 is rotatably arranged in the tower body 1, and in the initial state, the output port of the steam output terminal 501 faces the direction of the steam input module;

[0042] Each steam output terminal 501 is connected to a rotating module that drives its reciprocating rotation.

[0043] It can be explained that during wastewater treatment, the wastewater to be treated is sprayed into the tower body 1 through the spray module. At the same time, the steam input module synchronously inputs steam into the tower body 1 through the steam output terminal 501, and the steam can flow upward from the output port of the steam output terminal 501 (see [link]). Figure 3 At this point, the wastewater exchanges heat with the steam during the dripping process, vaporizing the organic matter in the wastewater. Finally, the organic matter in the wastewater is discharged through the stripping steam pipe 102. In this embodiment, a rotating module is set to synchronously drive each steam output end 501 to reciprocate within the tower body 1, thereby adjusting the output angle of the steam from the steam output end 501 and expanding the output range of the steam within the tower body 1. This ensures that there is rising steam at all positions within the tower body 1, effectively preventing the phenomenon of no heat exchange when wastewater drips in a direction away from the steam output end 501. Furthermore, each steam output end 501 is arranged circumferentially, so that a small number of steam output ends 501 can meet the heat exchange requirements, saving costs.

[0044] Example 2

[0045] Based on Example 1, please refer to Figures 2-3The bottom of the tower body 1 is provided with a storage chamber 109 for storing sewage. One side of the storage chamber 109 is connected to a sewage input pipe 103 for inputting sewage to be treated into the storage chamber 109. The spray module includes a spray plate 304 arranged at the top of the tower body 1. Several sets of spray plates 305 are arranged in a circumferential array on the outer edge of the spray plate 304. Liquid delivery chambers 306 are opened in both the spray plates 305 and the spray plate 304. Several sets of nozzles 307 communicating with the liquid delivery chambers 306 are evenly arranged at the bottom of each spray plate 305. The top of the tower body 1 rotates the spray plate 305. A delivery pipe 3 is provided, one end of which is connected to the spray plate 304, and the other end is connected to the storage chamber 109 through the return pipe 105. The return pipe 105 is equipped with a pump body 104. It can be explained that in this embodiment, the sewage to be treated is first input into the storage chamber 109 through the delivery pipe 3, and then the sewage in the storage chamber 109 is transported to the delivery chamber 306 of the spray plate 304 and the spray plate 305 through the return pipe 105 and the delivery pipe 3 by the pump body 104, and finally sprayed into the tower body 1 through the nozzle 307.

[0046] It should also be noted that in this embodiment, the sewage to be treated is pre-input into the storage chamber 109 through the sewage input pipe 103. The sewage can be pressurized to a saturated water state based on the pressure in the tower body 1, so as to improve the subsequent heat exchange efficiency and enable the organic matter in the sewage to be rapidly vaporized.

[0047] In this embodiment, please refer to Figures 2-3 The tower body 1 is also provided with a conical guide plate 107. The outer edge of the conical guide plate 107 is attached and fixed to the inner wall of the tower body 1. The bottom of the tower body 1 is provided with a liquid storage tank 101. The liquid storage tank 101 has a liquid storage trough 106. The bottom of the conical guide plate 107 is connected to the liquid storage trough 106 through a conduit 108. It can be explained that in this embodiment, after the wastewater dripping from the spray exchanges heat with the steam, it continues to drip down onto the conical guide plate 107, slides down along the conical guide plate 107, and is finally discharged into the liquid storage trough 106 through the conduit 108 for temporary storage.

[0048] Correspondingly, a detector is installed in the storage tank 106. When the sewage in the storage tank 106 reaches a preset amount, the pump body 104 is turned off. At this time, the sewage is tested to see if it is qualified. If it is qualified, it is discharged through the drain outlet on one side of the storage tank 106. If it is unqualified, the sewage is fed back into the storage chamber 109 for treatment by the circulation pump on one side of the storage tank 106. Compared with the prior art, this embodiment can separate the qualified water from the untreated sewage, preventing the qualified water from falling back into the storage chamber 109 for treatment, thus improving the treatment efficiency. On the other hand, the treated water can be detected in real time. Even if there is an unqualified phenomenon, it can be circulated back into the storage chamber 109 for treatment again, ensuring the stability of the treatment.

[0049] In addition, in this embodiment, a liquid level sensor can be installed in the liquid storage tank 106 to monitor its liquid level in real time.

[0050] As a further embodiment, one end of the infusion pipe 3 is rotatably connected to the return pipe 105, and the other end is fixed to the spray plate 304. A first gear 301 is fixedly arranged on the outer side of the top of the infusion pipe 3, and a servo motor 303 is fixedly arranged on the top of the tower body 1. The output end of the servo motor 303 is fixed to a second gear 302, and the second gear 302 meshes with the first gear 301. It can be explained that in order to improve the uniformity of the sewage spraying in the tower body 1, this embodiment can drive the second gear 302 to rotate through the servo motor 303. The second gear 302 drives the infusion pipe 3 to rotate through the meshing with the first gear 301. The infusion pipe 3 synchronously drives each spray plate 305 to rotate in the tower body 1 through the spray plate 304, thereby increasing the spray range of each nozzle 307. At the same time, under the action of centrifugal force, the sewage can be dispersed into fine particles, improving the subsequent heat exchange efficiency.

[0051] Please see Figures 2-3 Each spray plate 305 has a fixed support rod 402 at its bottom. Several sets of tower plates 4 are fixedly arranged at intervals along the vertical direction on each support rod 402. Several sets of through holes 401 are evenly opened on the tower plates 4. It can be explained that when the spray plate 305 rotates, the spray plate 305 can drive each tower plate 4 to rotate synchronously through the support rod 402. After the sewage is sprayed out by each nozzle 307, it first falls onto the spray plate 305, which can further refine the dripping sewage particles. In addition, the tower plate 4 in this embodiment is provided with multiple layers. While refining the sewage particles, it can prolong the time of sewage dripping, so that the steam can fully contact the sewage when it flows upward, and further improve the heat exchange effect.

[0052] In this embodiment, please refer to Figures 3-5 The steam input module includes an annular pipe 5 installed in the tower body 1. Each steam output end 501 is connected to the annular pipe 5 via a branch pipe 502. The steam input module also includes a rectangular pipe 2 installed on the outside of the tower body 1. The outside of the rectangular pipe 2 is connected to the main steam pipe 202. The inside of the rectangular pipe 2 is connected to the annular pipe 5 via several sets of steam input pipes 201. It can be noted that in this embodiment, steam is first input into the rectangular pipe 2 through the main steam pipe 202, then steam is transported to the annular pipe 5 through the steam input pipes 201, and finally transported to the steam output end 501 and output to the tower body 1 via each branch pipe 502.

[0053] Each steam output end 501 has its two ends fixed to a baffle 601. The two side baffles 601 are rotatably connected to the supports 507 fixed on the annular pipe 5 via support shafts 508. A third gear 602 is fixedly arranged between the two side baffles 601. The third gear 602 is coaxially arranged with the two side support shafts 508. A rack 603 that meshes with the third gear 602 is slidably arranged between the two side supports 507. The rack 603 is connected to a pushing part that drives it to slide back and forth on the annular pipe 5. It can be explained that in this embodiment, the rack 603 is driven to slide back and forth on the annular pipe 5 by the pushing part. During the movement, the rack 603 drives the baffles 601 and the support shafts 508 to rotate by meshing with the third gear 602. The baffles 601 can then synchronously drive the steam output end 501 to rotate for angle adjustment.

[0054] Specifically, the driving part includes an annular frame 504 arranged on the outside of the annular tube 5. The annular frame 504 is coaxially arranged with the annular tube 5 and fixed to the support rod 402. Several sets of arc-shaped protrusions 505 are fixedly arranged in a circumferential array on the side of the annular frame 504 near the axis. Two sets of adjacent arc-shaped protrusions 505 are supported by arc-shaped grooves 506. A positioning frame 607 is fixedly arranged at one end of the rack 603 near the annular frame 504. A guide wheel 6 is rotatably arranged at the end of the positioning frame 607 away from the rack 603. The guide wheel 6 is used to roll and abut against the arc-shaped protrusions 505 and the arc-shaped grooves 506. The other end of the rack 603 is connected to an elastic mechanism arranged on the annular tube 5. It can be explained that when When the guide wheel 6 abuts against the middle position of the arc-shaped groove 506, the elastic mechanism is in its natural state, and each steam output end 501 is tilted towards the axis of the annular pipe 5. As the spray plate 305 rotates, the annular frame 504 can be driven to rotate synchronously through the support rod 402. Based on the setting of the arc-shaped protrusion 505, the guide wheel 6 can be limited. The guide wheel 6 drives the rack 603 to move towards the axis through the positioning frame 607, and then drives the steam output end 501 to tilt away from the axis through the third gear 602. At this time, the elastic mechanism is in a contracted state. As the annular frame 504 continues to rotate, the elastic mechanism can drive the guide wheel 6 to reset and abut against the arc-shaped groove 506, and so on.

[0055] It should also be noted that in this embodiment, there is no need to use other servo drive devices to drive the steam output end 501 to rotate. The steam output end 501 can be driven to reciprocate at the same time as the spray plate 305 rotates. This can save costs, improve the stability of its rotation, and achieve the effect of synchronous operation.

[0056] In addition, in order to ensure that the steam output end 501 can rotate stably, a telescopic pipe 503 is installed in the branch pipe 502.

[0057] In this embodiment, the elastic mechanism includes a guide rod 605 fixedly arranged on the inner edge of the annular tube 5, an L-shaped bracket 604 fixed to the rack 603 slidably arranged on the guide rod 605, and a telescopic spring 606 provided on the guide rod 605; specifically, one end of the telescopic spring 606 is fixed to the L-shaped bracket 604, and the other end is fixed to the end of the guide rod 605; it can be explained that when the rack 603 moves, the rack 603 synchronously drives the L-shaped bracket 604 to slide on the guide rod 605, so as to stretch or contract the telescopic spring 606, thereby realizing the conversion of elastic force.

[0058] A method for operating a high flash stripping tower includes the following steps:

[0059] Please see Figures 1-3 The infusion tube 3 inputs the wastewater to be treated into the storage chamber 109;

[0060] Please see Figures 4-5 The pump body 104 transports the sewage in the storage chamber 109 to the delivery chamber 306 of the spray plate 304 and the spray plate 305 via the return pipe 105 and the delivery pipe 3, and sprays it into the tower body 1 via the nozzle 307.

[0061] Steam is fed into rectangular pipe 2 through main steam pipe 202, and then transported to ring pipe 5 through steam input pipe 201. The steam is then transported to steam output end 501 through each branch pipe 502 and output to tower body 1.

[0062] The servo motor 303 drives the second gear 302 to rotate. The second gear 302 drives the infusion pipe 3 to rotate by meshing with the first gear 301. The infusion pipe 3 drives each spray plate 305 to rotate in the tower body 1 synchronously through the spray plate 304.

[0063] As the spray plate 305 rotates, the ring frame 504 is driven to rotate synchronously through the support rod 402. Based on the setting of the arc-shaped protrusion 505 and the arc-shaped groove 506, the guide wheel 6 is limited. The guide wheel 6 drives the rack 603 to reciprocate synchronously through the positioning frame 607. During the movement, the rack 603 drives the baffle 601 and the support shaft 508 to rotate by meshing with the third gear 602. The baffle 601 synchronously drives the steam output end 501 to rotate for angle adjustment.
