Description

Technical Field

[0001] This invention relates to the field of resin scrubbing technology, specifically to an automatic detection device for resin scrubbing in high-speed mixed bed condensate polishing. Background Technology

[0002] High-speed mixed bed reactors are mainly used to remove trace amounts of dissolved salt ions from condensate. Two units share a single high-speed mixed bed resin in vitro separation and regeneration system. The resin in vitro separation process uses a high-tower method. Because the mixed resin in the high-speed mixed bed requires in vitro regeneration, the in vitro regeneration process includes many steps such as: output of cation and anion mixed resin from the high-speed mixed bed, separation of cation and anion resins, scrubbing, regeneration, rinsing, mixing, and finally, return of the resin to the high-speed mixed bed from the separation system. The separation tower, along with the cation regeneration tower and anion regeneration tower, forms a three-tower in vitro regeneration system for regenerating the resin in the high-speed mixed bed. The resin undergoes air scrubbing in the separation tower, cation regeneration tower, and anion regeneration tower. Resin air scrubbing refers to the process of using a Roots blower to force air into the equipment and violently agitate the resin. To ensure the effectiveness of resin scrubbing and prevent resin leakage during the scrubbing process, the water level needs to be precisely controlled during the resin scrubbing step. The scrubbing water level must be controlled to be neither lower than the resin surface nor too high.

[0003] However, in existing high-speed mixed bed resin scrubbing methods for condensate polishing, the internal condition can only be observed through a few transparent sight glasses. Even with manual on-site observation, it is difficult to control the liquid level within the container. If the water level is not properly controlled and falls below the resin surface, the resin will not mix sufficiently. Insufficiently mixed resin, when transported to the high-speed mixed bed, will affect both the water production and the quality of the effluent. If the water level is too high, the resin will not drain in time after mixing, and due to the difference in volume between the cation and anion resins, stratification of the cation and anion resins may occur. In addition, excessively high water levels can cause resin to leak through the top vent during the scrubbing process. Furthermore, it is inconvenient to test the scrubbing effect after the scrubbing is completed, which not only affects the effectiveness of the resin scrubbing but also wastes resources.

[0057] Compared with the prior art, the beneficial effects of the present invention are:

[0058] (1) This automatic detection device for resin scrubbing in high-speed mixed bed condensate polishing, through the setting of a liquid level adjustment mechanism, opens the air inlet valve during resin scrubbing and uses a Roots blower to blow air into the tower through the air inlet valve, violently agitating the resin. At the same time, the liquid inlet valve is opened, and demineralized water is supplied into the tower through the L-shaped pipe and the liquid inlet valve. Acid / alkali is introduced through the acid / alkali inlet valve, and the liquid outlet valve is opened for drainage. During scrubbing, the resin scrubbing water is discharged through the liquid outlet valve and the liquid outlet pipe. During discharge, the turbidity index of the resin scrubbing water can be detected online by a turbidity sensor, realizing the automatic evaluation of the resin scrubbing effect, improving the resin regeneration effect, and saving energy, water, acid and alkali consumption. In addition, the liquid level sensor can detect the liquid level in the tower. When the liquid level is low, the moving module is activated, causing the first L-shaped block to move upward. Simultaneously, the push pin moves upward along the inclined groove, pushing the sliding plate away from the fixed cover. The second elastic element is stretched, reducing the overlap area between the circular hole and the liquid outlet pipe, thus decreasing the water flow rate and raising the liquid level inside the tower. When the liquid level is high, the moving module is activated, causing the first L-shaped block to move downward. Simultaneously, the push pin moves downward along the inclined groove, pushing the sliding plate into the fixed cover. The second elastic element is compressed, increasing the overlap area between the circular hole and the liquid outlet pipe, thus increasing the water flow rate and lowering the liquid level inside the tower. This facilitates automatic detection and adjustment of the liquid level inside the tower, ensuring the effectiveness of resin scrubbing.

[0059] (2) This automatic detection device for resin scrubbing in high-speed mixed bed condensate polishing utilizes a bubble-breaking mechanism, allowing the buoyancy shield and buoyancy plate to float on the liquid surface under buoyancy, reducing surface fluctuations and improving the accuracy of the liquid level sensor. Simultaneously, during resin scrubbing, demineralized water enters the buoyancy shield through an L-shaped pipe and inlet valve, then through a flexible hose, and finally into the tower body through the outlet, further reducing surface fluctuations and improving the accuracy of the liquid level sensor. Furthermore, when demineralized water enters through the L-shaped pipe, it enters the fixed chamber and impacts the surface of the blades, thereby reducing surface fluctuations and improving the accuracy of the liquid level sensor. The drive shaft rotates, which in turn drives the rotating shaft and the first scraper to rotate via the insert plate. When the first scraper rotates, it drives the stirring rod to rotate via the L-shaped frame, thereby stirring the resin particles and improving the efficiency and effect of scrubbing. Furthermore, the moving disc can move synchronously with the buoyancy cover and buoyancy plate, keeping the conical rod above the liquid surface. At the same time, when the L-shaped frame rotates, it drives the moving disc and the conical rod to rotate via the second connecting plate and the stirring rod. The conical rod can break up air bubbles on the liquid surface, making the liquid level sensor detect the liquid level more accurately, thus ensuring the effect of resin scrubbing.

[0060] (3) This automatic detection device for resin scrubbing in high-speed mixed bed condensate polishing, through the installation of protective mechanisms, can block resin particles and prevent overflow when the liquid level in the tower is high during resin scrubbing, under the action of the filter plate. At the same time, when the first L-shaped block is moved downward by the moving module, the second L-shaped block can pull the pull rope, thereby pulling the filter plate upward. The third elastic element is compressed and drives the first scraper upward through the rotating shaft. When the rotating shaft rotates, it can drive the first scraper to rotate, thereby scraping and cleaning the resin particles adhering to the surface of the filter plate. At the same time, under the centrifugal force... The material is thrown against the inner wall of the annular cover. When the rotating shaft moves upward, it can drive the second scraper upward through the L-shaped frame and the first telescopic component. When the inclined surface abuts against the bottom of the annular cover, it can push the second scraper to move closer to the L-shaped frame. At the same time, the first elastic element is compressed. When the second scraper moves into the annular cover, under the action of the first elastic element, the second scraper abuts against the inner wall of the annular cover. It can also rotate with the rotation of the rotating shaft, thereby scraping and cleaning the resin particles adhering to the inner wall of the annular cover and letting them fall back into the tower body. This ensures the gas outlet valve's gas outlet effect while avoiding the waste of resin particles and ensuring the cleaning effect. Attached Figure Description

The third elastic elements 1003 are located between the filter disc 202 and the annular cover 201, and play a guiding and resetting role for the movement of the filter disc 202.

[0124] Working Principle: During resin scrubbing, the air inlet valve 105 is opened, and a Roots blower is used to blow air into the tower body 1 through the air inlet valve 105, violently agitating the resin. Simultaneously, the liquid inlet valve 103 is opened, and demineralized water is supplied into the tower body 1 through the L-shaped pipe 601 and the liquid inlet valve 103. Acid / alkali is introduced through the acid / alkali inlet valve 104, and the liquid outlet valve 101 is opened for drainage. During scrubbing, the resin scrubbing water is discharged through the liquid outlet valve 101 and the liquid outlet pipe 11. During discharge, the turbidity index of the resin scrubbing water can be detected online by the turbidity sensor 12, realizing the resin scrubbing effect. The automated evaluation of the results improves the resin regeneration effect while saving energy, water, acid and alkali consumption. Furthermore, the liquid level sensor 13 can detect the liquid level in the tower body 1. When the liquid level is low, the moving module 801 is activated, causing the first L-shaped block 802 to move upward. At the same time, it drives the push pin 803 to move upward along the inclined groove 804, thereby pushing the sliding plate 1402 to slide away from the fixed cover 1401. The second elastic element 2003 is stretched. At this time, the overlapping area of ​​the round hole 1403 and the liquid outlet pipe 11 becomes smaller, the water outlet speed decreases, and the liquid level in the tower body 1 increases.

[0125] When the liquid level is high, the moving module 801 is activated, causing the first L-shaped block 802 to move downward. At the same time, the pushing pin 803 moves downward along the inclined groove 804, thereby pushing the sliding plate 1402 to slide into the fixed cover 1401. The second elastic element 2003 is compressed. At this time, the overlapping area of ​​the round hole 1403 and the liquid outlet pipe 11 increases, the water outlet speed increases, and the liquid level in the tower body 1 decreases. This facilitates automatic detection and adjustment of the liquid level in the tower body 1, ensuring the effect of resin scrubbing.

[0126] Under the action of buoyancy, the buoyancy shield 15 and the buoyancy plate 18 can float on the liquid surface, which can reduce the fluctuation of the liquid surface and make the liquid level sensor 13 detect the liquid level more accurately. At the same time, during resin scrubbing, the demineralized water enters the buoyancy shield 15 through the L-shaped pipe 601 and the liquid inlet valve 103, and then enters the tower body 1 through the liquid outlet 16, which can also reduce the fluctuation of the liquid surface and make the liquid level sensor 13 detect the liquid level more accurately.

[0127] Meanwhile, when the demineralized water enters through the L-shaped pipe 601, it enters the fixed box 602 and impacts the surface of the blade 604, causing the blade 604 and drive shaft 603 to rotate. This, in turn, drives the rotating shaft 203 and the first scraper 204 to rotate via the insert plate 605. When the first scraper 204 rotates, it drives the stirring rod 403 to rotate via the L-shaped frame 401, thereby stirring the resin particles and improving the efficiency and effect of scrubbing. Furthermore, the moving disk 501 can move synchronously with the buoyancy cover 15 and the buoyancy plate 18, keeping the conical rod 503 above the liquid surface. At the same time, when the L-shaped frame 401 rotates, it drives the moving disk 501 and the conical rod 503 to rotate via the second connecting plate 402 and the stirring rod 403. The conical rod 503 can break the air bubbles on the liquid surface, making the liquid level sensor 13 more accurate in detecting the liquid level, thus ensuring the effect of resin scrubbing.

[0128] During resin scrubbing, when the liquid level in the tower body 1 is high, the filter disc 202 can block the resin particles and prevent overflow. At the same time, when the first L-shaped block 802 is moved downward by the moving module 801, the second L-shaped block 905 can pull the pull rope 904, thereby pulling the filter disc 202 upward. The third elastic element 1003 is compressed and drives the first scraper 204 upward through the rotating shaft 203. When the rotating shaft 203 rotates, it can drive the first scraper 204 to rotate, thereby scraping and cleaning the resin particles adhering to the surface of the filter disc 202. At the same time, under the action of centrifugal force, they are thrown onto the inner wall of the annular cover 201.

[0129] Furthermore, when the rotating shaft 203 moves upward, it can drive the second scraper 301 to move upward through the L-shaped frame 401 and the first telescopic component. When the inclined surface 302 abuts against the bottom of the annular cover 201, it can push the second scraper 301 to move closer to the L-shaped frame 401. At the same time, the first elastic element 703 is compressed. When the second scraper 301 moves into the annular cover 201, under the action of the first elastic element 703, the second scraper 301 abuts against the inner wall of the annular cover 201. It can also rotate with the rotation of the rotating shaft 203, thereby scraping and cleaning the resin particles adhering to the inner wall of the annular cover 201 and letting them fall back into the tower body 1. This ensures the air outlet effect of the air outlet valve 102 while avoiding the waste of resin particles and ensuring the cleaning effect.
