Description

Technical Field

[0001] The invention relates to the technical field of resin scrubbing, in particular to an automatic detection device for scrubbing resin for a high-speed mixed bed for condensate polishing. Background Art

[0002] The high-speed mixed bed is mainly used to remove trace soluble salt ions in condensate water. The two units share a high-speed mixed bed resin in vitro separation and regeneration system. The resin in vitro separation process adopts the high tower method. The high-speed mixed bed needs in vitro regeneration due to its mixed resin. The in vitro regeneration process includes: the cation and anion mixed resins are output from the high-speed mixed bed, the cation and anion resins are separated, scrubbed, regenerated, rinsed, mixed, and finally transported back to the high-speed mixed bed by the separation system. The separation tower, the cation regeneration tower, the anion regeneration tower, etc. together form a three-tower in vitro regeneration system for regenerating the resin in the high-speed mixed bed. The resin must be air scrubbed in the separation tower, the cation regeneration tower, and the anion regeneration tower. The so-called resin air scrubbing refers to the process of using a Roots blower to blow air into the equipment and violently stir the resin. In order to ensure the resin scrubbing effect and prevent the resin from leaking during the scrubbing process, the water level needs to be accurately controlled in the resin scrubbing step. The scrubbing water level needs to be controlled neither lower than the resin surface nor too high.

[0003] However, when the existing condensate polishing high-speed mixed bed is scrubbed with resin, the internal situation can only be observed through several transparent sight glasses. Even if it is observed manually on site, it is difficult to grasp the liquid level situation in the above-mentioned container equipment. If the water level is not properly controlled and the water level is lower than the resin surface, the resin cannot be fully mixed. After the insufficiently mixed resin is transported to the high-speed mixed bed, its water production and effluent water quality will be affected. If the water level is too high, the drainage is not timely after the resin is mixed. Due to the different volumes of the cation and anion resins, stratification of the cation and anion resins may occur. In addition, the water level is too high and the resin will leak through the top exhaust valve during the resin scrubbing process. Moreover, after the scrubbing is completed, it is not convenient to detect the scrubbing effect, which not only affects the resin scrubbing effect, but also causes a waste of resources.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] (1) This condensate polishing high-speed mixed bed resin scrubbing automatic detection device is provided with a liquid level regulating mechanism, etc., when performing resin scrubbing, the air inlet valve is opened, and a Roots blower is used to blow air into the tower body through the air inlet valve to violently stir the resin. At the same time, the liquid inlet valve is opened, and desalted water is supplied into the tower body through the L-shaped tube and the liquid inlet valve, and acid / alkali is introduced through the acid and alkali inlet valves. In addition, the liquid outlet valve is opened for drainage. When scrubbing, the resin scrubbing water is discharged through the liquid outlet valve and the liquid outlet pipe. When being discharged, the turbidity index of the resin scrubbing water can be detected online by a turbidity sensor, so as to realize the automatic evaluation of the resin scrubbing effect, improve the resin regeneration effect, and save energy, water, acid and alkali consumption, etc. In addition, the liquid level in the tower body can be detected by the liquid level sensor. When the liquid level is low, the moving module is started to move the first L-shaped block upward, and at the same time, the pushing pin is driven to move upward along the inclined groove, so that the sliding plate can be pushed to slide in the direction away from the fixed cover, and the second elastic member is stretched. At this time, the overlapping area between the circular hole and the liquid outlet pipe becomes smaller, so that the water outlet speed becomes smaller, and the liquid level in the tower body can be increased. When the liquid level is high, the moving module is started to move the first L-shaped block downward, and at the same time, the pushing pin is driven to move downward along the inclined groove, so that the sliding plate can be pushed to slide into the fixed cover, and the second elastic member is compressed. At this time, the overlapping area between the circular hole and the liquid outlet pipe becomes larger, so that the water outlet speed becomes larger, and the liquid level in the tower body can be lowered, thereby facilitating automatic detection and automatic adjustment of the liquid level in the tower body to ensure the effect of resin scrubbing.

[0059] (2) This type of condensate polishing high-speed mixed bed resin scrubbing automatic detection device, by setting a bubble bursting mechanism, etc., the buoyancy cover and the buoyancy plate can float on the liquid surface under the action of buoyancy, which can reduce the fluctuation of the liquid surface, making the liquid level sensor detect the liquid level more accurately. At the same time, when the resin scrubbing is performed, the desalted water passes through the L-shaped tube and the liquid inlet valve and then enters the buoyancy cover through the hose, and enters the tower body through the liquid outlet hole, which can also reduce the fluctuation of the liquid surface, making the liquid level sensor detect the liquid level more accurately. At the same time, when the desalted water enters through the L-shaped tube, it will enter the fixed box and impact the surface of the blade, thereby making the blade and the driving shaft rotates, and then the rotating shaft and the first scraper are driven to rotate through the plug plate. When the first scraper rotates, the stirring rod can be driven to rotate through the L-shaped frame, so that the resin particles can be stirred, which can improve the efficiency and effect of scrubbing, and the movable plate can move synchronously with the buoyancy cover and the buoyancy plate, so that the conical rod is above the liquid surface. At the same time, when the L-shaped frame rotates, the movable plate and the conical rod can be driven to rotate through the second connecting plate and the stirring rod, and the bubbles on the liquid surface can be burst by the conical rod, so that the liquid level sensor can detect the liquid level more accurately, thereby ensuring the effect of resin scrubbing.

[0060] (3) This type of automatic detection device for resin scrubbing of a high-speed mixed bed for condensate polishing treatment is provided with a protective mechanism, etc., so that when the liquid level in the tower body is high during resin scrubbing, the resin particles can be blocked by the filter disc to prevent overflow. At the same time, when the first L-shaped block is driven downward by the moving module, the pull rope can be pulled by the second L-shaped block, thereby pulling the filter disc upward. The third elastic member is compressed and drives the first scraper to move 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 adhered to the surface of the filter disc. At the same time, under the centrifugal force, The scraper is thrown on the inner wall of the annular cover under the action of the first elastic member, and when the rotating shaft moves upward, the second scraper can be driven to move upward through the L-shaped frame and the first telescopic assembly. When the inclined surface abuts against the bottom of the annular cover, the second scraper can be pushed to move in the direction close to the L-shaped frame. At the same time, the first elastic member is compressed. When the second scraper moves into the annular cover, under the action of the first elastic member, the second scraper abuts against the inner wall of the annular cover, and can rotate with the rotation of the rotating shaft, so that the resin particles adhered to the inner wall of the annular cover can be scraped and cleaned and fall back into the tower body, thereby ensuring the exhaust effect of the exhaust valve and avoiding the waste of resin particles, thereby ensuring the scrubbing effect.

At the same time, when the first L-shaped block 802 is driven to move downward by the moving module 801, the pull rope 904 can be pulled by the second L-shaped block 905, thereby pulling the filter disc 202 upward.

[0120] See also Figure 8 , the second telescopic mechanism comprises:

[0121] Two second sets of rods 1001 are fixed on the top of the filter plate 202 .

[0122] The two second sleeves 1002 are sleeved on the side walls of the second sleeve rod 1001 and fixed to the bottom of the annular cover 201 .

[0123] Two third elastic members 1003, the third elastic member 1003 can be a spring, and the two ends of the third elastic member 1003 are respectively fixed to the filter plate 202 and the annular cover 201, and are sleeved on the side wall of the second sleeve 1002. The third elastic member 1003 is located between the filter plate 202 and the annular cover 201, and plays a guiding and resetting role in the movement of the filter plate 202.

[0124] Working principle: When in use, when scrubbing the resin, open the air inlet valve 105, and use the Roots blower to blow air into the tower body 1 through the air inlet valve 105 to vigorously stir the resin. At the same time, open the liquid inlet valve 103, supply deionized water into the tower body 1 through the L-shaped tube 601 and the liquid inlet valve 103, and add acid / alkali through the acid and alkali inlet valve 104. In addition, open the liquid outlet valve 101 to drain water. When scrubbing, the resin scrubbing water is discharged through the liquid outlet valve 101 and the liquid outlet pipe 11. When discharged, the turbidity index of the resin scrubbing water can be detected online through the turbidity sensor 12 to achieve the resin scrubbing effect. The automatic evaluation of the results can improve the resin regeneration effect while saving energy, water, acid and alkali consumption. In addition, the liquid level in the tower body 1 can be detected by the liquid level sensor 13. When the liquid level is low, the moving module 801 is started to move the first L-shaped block 802 upward. At the same time, the pushing pin 803 is driven to move upward along the inclined groove 804, so that the sliding plate 1402 can be pushed to slide away from the fixed cover 1401, and the second elastic member 2003 is stretched. At this time, the overlapping area of ​​the circular hole 1403 and the liquid outlet pipe 11 becomes smaller, so that the water outlet speed becomes smaller, and the liquid level in the tower body 1 can be increased.

[0125] When the liquid level is high, the moving module 801 is started to move the first L-shaped block 802 downward, and at the same time, the pushing pin 803 is driven to move downward along the inclined groove 804, thereby pushing the sliding plate 1402 to slide into the fixed cover 1401, and the second elastic member 2003 is compressed. At this time, the overlapping area between the circular hole 1403 and the liquid outlet pipe 11 becomes larger, so that the water outlet speed becomes faster, and the liquid level in the tower body 1 can be lowered, thereby facilitating automatic detection and automatic adjustment of the liquid level in the tower body 1 to ensure the effect of resin scrubbing.

[0126] Under the action of buoyancy, the buoyancy cover 15 and the buoyancy plate 18 can float on the liquid surface, which can reduce the fluctuation of the liquid surface, making the liquid level detection of the liquid level by the liquid level sensor 13 more accurate. At the same time, when the resin is scrubbed, the desalted water passes through the L-shaped tube 601 and the liquid inlet valve 103 and then enters the buoyancy cover 15 through the hose 17, and enters the tower body 1 through the liquid outlet 16, which can also reduce the fluctuation of the liquid surface, making the liquid level detection of the liquid level by the liquid level sensor 13 more accurate.

[0127] At the same time, when the desalted water enters through the L-shaped tube 601, it will enter the fixed box 602 and impact the surface of the blade 604, so that the blade 604 and the drive shaft 603 rotate, and then the rotating shaft 203 and the first scraper 204 are driven to rotate through the plug plate 605. When the first scraper 204 rotates, the stirring rod 403 can be driven to rotate through the L-shaped frame 401, so that the resin particles can be stirred, which can improve the efficiency and effect of scrubbing. In addition, the movable plate 501 can move synchronously with the buoyancy cover 15 and the buoyancy plate 18, so that the conical rod 503 is above the liquid surface. At the same time, when the L-shaped frame 401 rotates, the movable plate 501 and the conical rod 503 can be driven to rotate through the second connecting plate 402 and the stirring rod 403, and the bubbles on the liquid surface can be broken by the conical rod 503, so that the liquid level sensor 13 can detect the liquid level more accurately, thereby ensuring the effect of resin scrubbing.

[0128] When scrubbing the resin, when the liquid level in the tower body 1 is high, the resin particles can be blocked by the filter disc 202 to prevent overflow. At the same time, when the first L-shaped block 802 is driven to move downward by the moving module 801, the pull rope 904 can be pulled by the second L-shaped block 905, thereby pulling the filter disc 202 upward. The third elastic member 1003 is compressed and drives the first scraper 204 to move 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 adhered to the surface of the filter disc 202, and at the same time, they are thrown onto the inner wall of the annular cover 201 under the action of centrifugal force.

[0129] Furthermore, when the rotating shaft 203 moves upward, the second scraper 301 can be driven to move upward through the L-shaped frame 401 and the first telescopic assembly. When the inclined surface 302 abuts against the bottom of the annular cover 201, the second scraper 301 can be pushed to move toward the L-shaped frame 401. At the same time, the first elastic member 703 is compressed. When the second scraper 301 moves into the annular cover 201, under the action of the first elastic member 703, the second scraper 301 abuts against the inner wall of the annular cover 201, and can rotate with the rotation of the rotating shaft 203, so that the resin particles adhered to the inner wall of the annular cover 201 can be scraped and cleaned and fall back into the tower body 1, thereby ensuring the exhaust effect of the exhaust valve 102 while avoiding the waste of resin particles and ensuring the scrubbing effect.
