Description

Technical Field

[0001] The invention relates to the technical field of residual chlorine detection, and in particular to a residual chlorine qualitative continuous detection device. Background Art

[0002] In the preparation process of desalted water in thermal power plants, sodium hypochlorite solution is needed for sterilization and disinfection to remove organic microorganisms in the water to prevent them from causing organic pollution to water-making equipment. However, since sodium hypochlorite has a strong oxidizing property, it will cause irreversible damage to the reverse osmosis membrane and cation and anion resins. A reducing agent needs to be added in front of these devices to react with excess residual chlorine to achieve the purpose of sterilizing the water without damaging subsequent equipment. Therefore, it is very important to detect the residual chlorine concentration in front of the reverse osmosis equipment.

[0003] At present, the detection of residual chlorine concentration requires the use of a portable residual chlorine detector, which produces a color reaction with residual chlorine in a test by dropping o-tolidine, and then performs visual colorimetry or microcomputer photoelectric colorimetry detection. When using a portable residual chlorine detector to detect residual chlorine in water samples, online real-time monitoring is not possible. Since it is a manual operation, increasing the detection frequency can greatly increase the workload of manual labor, but real-time monitoring is also impossible. Summary of the invention

[0031] Example 1

[0032] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a residual chlorine qualitative continuous detection device, the device comprising:

[0033] The detection mechanism 100 includes a dosing box 101 and a detection box 102. The dosing box 101 and the detection box 102 are connected via a connecting pipe 103. A liquid inlet pipe 104 is fixedly connected to the outer side of the dosing box 101. A liquid outlet pipe 105 is fixedly connected to the outer side of the detection box 102. A dosing pump 106 is provided at the top end of the dosing box 101. A mixing component 107 is provided at the bottom end of the dosing pump 106.

[0034] Specifically, a color sensor 102 a is adapted to be installed on the top of the detection box 102 , and the color sensor 102 a is located at the center of the detection box 102 .

[0035] Furthermore, one end of the liquid inlet pipe 104 is fixedly connected to a mounting ring 104a, and a liquid inlet hole 104b is formed on the inner side of the mounting ring 104a.

[0036] Furthermore, the input end of the dosing pump 106 is fixedly connected to an input pipe 106a, the output end of the dosing pump 106 is fixedly connected to an output pipe 106b, a medicine box is provided at one end of the input pipe 106a, and a convex ring is fixedly connected to the inner wall of the output pipe 106b.

[0037] Preferably, the mixing component 107 includes a rotating tube 107a rotatably connected to the inside of the output tube 106b, and a medicine storage chamber 107b and a liquid storage chamber 107c opened inside the rotating tube 107a;

[0038] The rotating tube 107a is located inside the mounting ring 104a.

[0039] It should be noted that a groove 107d is provided on the outer side of the rotating tube 107a, a stirring blade 107e is fixedly connected to the outer bottom end of the rotating tube 107a, and a liquid leakage groove 107f is provided on the outer side of the rotating tube 107a;

[0040] The groove 107d is arranged outside the convex ring of the inner wall of the output pipe 106b.

[0041] Preferably, a medicine spreading hole 107b-1 is provided at the bottom end of the side wall of the medicine storage chamber 107b, and an impeller 107b-2 is fixedly connected to the top end of the interior of the medicine storage chamber 107b.

[0042] When in use, the dosing pump 106 is started, and the medicine liquid in the medicine box can be output from the output pipe 106b through the dosing pump 106 and enter the inside of the rotating tube 107a. Under the impeller 107b-2 set inside the rotating tube 107a, the rotating tube 107a can be driven to rotate inside the output pipe 106b. The medicine liquid entering the rotating tube 107a will be located in the medicine storage cavity 107b, and will flow out through the medicine spreading hole 107b-1 under the continuous rotation of the rotating tube 107a and enter the inside of the dosing box 101. At this time, the sampled water will also flow into the dosing box 101 through the liquid inlet pipe 104, so that the sampled water and the medicine liquid are mixed in the dosing box 101. The spread medicine liquid can be more comprehensively contacted and mixed with the sampled water to ensure the accuracy of the subsequent detection by the color sensor 102a.

[0043] The mixing effect of the medicine solution and the sampling water in the medicine adding box 101 can be further improved by rotating the stirring piece 107e outside the rotating tube 107a.

[0044] The mixed sampled water will flow into the detection box 102 through the connecting pipe 103, and the sampled water can be detected through the color sensor 102a. If there is no residual chlorine in the sampled water, the sampled water will not change color. If there is residual chlorine in the sampled water, the sampled water will turn yellow. The darker the yellow, the higher the residual chlorine concentration. The mixed liquid that has completed the detection will be discharged through the sampled water outlet pipeline.

[0045] In summary, through the above process, real-time monitoring can be achieved without the need for human operation, which not only ensures the accuracy and real-time nature of data detection, but also reduces the workload of personnel.

[0046] Example 2

[0047] Reference Figure 1 to Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a through hole 107c-1 is provided on the inner wall of the liquid storage chamber 107c, and a liquid dispensing hole 107c-2 is provided on the bottom end of the inner wall of the liquid storage chamber 107c.

[0048] When the sampling water flows into the medicine dosing box 101 through the liquid inlet pipe 104, it first enters the interior of the mounting ring 104a, and flows into the interior of the liquid storage chamber 107c through the liquid inlet hole 104b on the inner side of the mounting ring 104a and the design of the through hole 107c-1. When the rotating tube 107a rotates, the sampling water located in the liquid storage chamber 107c can be dispersed through the liquid spreading hole 107c-2, ensuring that the sampling water can be fully and evenly fallen into the interior of the medicine dosing box 101 and mixed with the medicine liquid, thereby ensuring the final mixing effect.

[0049] Since the rotation of the rotating tube 107a causes the through hole 107c-1 and the liquid inlet hole 104b to be continuously connected in a staggered manner, the amount of water entering the liquid storage chamber 107c can be controlled, and part of the sampled water can be caused to flow down through the leakage groove 107f. Not only can the flow rate of the sampled water be controlled, but the sampled water can be added to different positions of the drug adding box 101 in two ways, thereby achieving effective mixing of the drug solution and the sampled water.

[0050] At the same time, since the amount of sampled water entering the liquid storage chamber 107c is controlled, the weight of the sampled water inside the rotating tube 107a can be reduced, thereby ensuring the overall power of the rotating tube 107a during rotation and the overall mixing effect of the mixing component 107 on the liquid medicine and the sampled water.

[0051] In summary, the equipment can not only realize real-time detection and monitoring of sampled water, but also does not require human operation, thereby reducing the number of personnel while ensuring the detection effect of sampled water. At the same time, through the design of the mixing component 107, the mixing effect of the liquid medicine and the sampled water can be effectively improved, thereby realizing accurate detection of the color sensor 102a.

[0052] Example 3

[0053] Reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the main body 200 includes a box body 201, a mounting plate 202 fixedly connected to the inner wall of the box body 201, and a PLC controller 203 adapted to be installed inside the box body 201, and an alarm light 204 is adapted to be installed on the outer side of the box body 201;

[0054] The dosing pump 106 is adapted to be installed at the top of the mounting plate 202 , and the output pipe 106 b penetrates through the mounting plate 202 and extends to the bottom of the mounting plate 202 .

[0055] Furthermore, the PLC controller 203 is connected to the color sensor 102 a , the dosing pump 106 , and the alarm light 204 by wires.

[0056] In summary, the PLC controller 203 can effectively receive the data detected by the color sensor 102a. If the value detected by the color sensor 102a exceeds the set threshold, the alarm light 204 will be activated to prompt the alarm light 204 to work, thereby reminding personnel to pay attention and enable personnel to discover in time.
