Description

Technical Field

[0001] The present invention belongs to the technical field of drinking water purification equipment, and in particular to an intelligent dosing system based on cloud computing. Background Art

[0002] In rural single-station water supply stations, chlorination treatment is mainly used to disinfect tap water. This is because chlorination treatment has low cost, simple operation, stable disinfection effect, and can effectively kill bacteria and viruses in the water.

[0003] Chlorination of tap water is to kill bacteria and viruses in the water by adding chlorine or chlorides, so as to achieve the purpose of disinfection. Sodium hypochlorite is widely used in the chlorination of tap water due to its advantages such as wide bactericidal spectrum, rapid action, reliable bactericidal effect and low toxicity. However, due to the unstable nature of sodium hypochlorite itself, it will decompose over time, under the influence of factors such as changes in ambient temperature and humidity, thereby reducing the concentration of stored sodium hypochlorite. This leads to a certain deviation between the amount of sodium hypochlorite added to tap water and the actual amount added, which makes the disinfection effect of tap water relatively unstable.

[0004] In order to enhance the stability of the sodium hypochlorite content in the related art, a sodium hypochlorite generator has been developed. By connecting the sodium hypochlorite with a water pump, the brine is electrolyzed during the process of the water pump pumping water, thereby producing sodium hypochlorite in real time and adding the sodium hypochlorite to the water flow, thereby ensuring that the actual amount of sodium hypochlorite added is consistent with the pre-set value.

[0005] For example, a sodium hypochlorite dosing device for industrial wastewater treatment is disclosed in a related patent, and the application number is CN2021207253618. In this scheme, the movement of the baffle and the protrusion is used to achieve the addition of the drug, and the distance between the baffle and the protrusion is relatively stable, so that the amount of single dosing can be constant, thereby achieving single quantitative dosing. However, due to the influence of environmental factors, the concentration of the stored sodium hypochlorite changes, resulting in a mismatch between the actual amount added and the actual effective amount.

[0006] The relevant patent also discloses a sodium hypochlorite dosing device for electrolysis of table salt, with application number CN2023209651290. In this scheme, the salt solution in the salt dissolving box is electrolyzed by the electrolysis host to generate sodium hypochlorite solution which enters the sodium hypochlorite storage tank, and the hyposulfuric acid storage tank is connected to the tap water pool through a pipeline equipped with a concentration analyzer, a flow meter and other equipment. During the flow of tap water, the sodium hypochlorite in the storage tank is passed into the tap water, thereby achieving the disinfection of the tap water. However, in actual application, During use, it was found that due to the irregularity of tap water consumption, the storage time of the generated sodium hypochlorite in the storage tank was inconsistent. When the storage tank volume was large, the stored sodium hypochlorite content was high and the generation time difference was large, which led to a large fluctuation in the concentration range of sodium hypochlorite in storage. When the storage volume was small, although it was convenient to detect the sodium hypochlorite concentration in the dosing pipe, when a large amount of water was used, the capacity of sodium hypochlorite stored in the storage was too small and the sodium hypochlorite generation rate could not meet the tap water disinfection needs.

[0007] In view of this, the present invention proposes an intelligent dosing system based on cloud computing to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] like Figures 1 to 10 As shown, the intelligent dosing system based on cloud computing described in the present invention includes a monitoring unit, a data control unit and a dosing unit;

[0049] The monitoring unit is used to monitor the residual chlorine and sodium hypochlorite concentration of tap water in real time;

[0050] The monitoring unit includes an online residual chlorine analyzer, a concentration analyzer and a data transmission component;

[0051] The residual chlorine online analyzer is installed in the clean water tank, and the residual chlorine online analyzer is used to monitor the residual chlorine in the clean water tank in real time. The concentration analyzer is used to monitor the concentration of sodium hypochlorite in the dosing pipe 21 in real time. The data transmission component is electrically connected to the residual chlorine online analyzer and the concentration analyzer, and the data transmission component transmits the measurement results of the residual chlorine online analyzer and the concentration analyzer to the data control unit;

[0052] The data control unit calculates the dosage through a preset algorithm program combined with the measurement result of the receiving monitoring unit, and controls the dosage unit in real time according to the calculation result;

[0053] The dosing unit is used to add sodium hypochlorite solution to tap water, and the dosing unit includes a sodium hypochlorite generator 1, a storage tank 2, a dosing pipe 21 and a reflux pipe 22;

[0054] The sodium hypochlorite generator 1 is used to electrolyze salt water into a sodium hypochlorite solution. The sodium hypochlorite generator 1 is connected to a storage tank 2 through a pipeline, and the storage tank 2 is used to store the sodium hypochlorite solution.

[0055] The sodium hypochlorite generator 1 and the storage tank 2 are jointly provided with a dosing pipe 21, and the dosing pipe 21 extends into the water inlet pipe of the clean water tank;

[0056] The storage tank 2 is provided with a reflux pipe 22 , and the reflux pipe 22 is used to guide the spent sodium hypochlorite solution to flow into the sodium hypochlorite generator 1 .

[0057] In the tap water disinfection system, the clear water tank is used to store the disinfected tap water. After the tap water is treated by multiple water purification equipment, it is passed into the clear water tank. In this process, the sodium hypochlorite solution and the treated tap water flow into the clear water tank at the same time, so that the tap water can be disinfected. In order to maintain a stable value for the added concentration of the sodium hypochlorite solution in the tap water, the present invention provides a dosing system and dynamically adjusts the dosing amount, thereby stabilizing the residual chlorine value in the tap water.

[0058] Specifically, the dosing system is composed of a monitoring unit, a data control unit and a dosing unit, wherein the sampling end of the residual chlorine online analyzer in the monitoring unit is installed in the clean water tank, and the residual chlorine content of the tap water in the clean water tank is detected to obtain the concentration of the sodium hypochlorite solution in the tap water, and the concentration analyzer is installed in the dosing pipe 21, which is used to detect the concentration of the sodium hypochlorite solution flowing in the dosing pipe 21. The detection results are sent to the data control unit in real time by the data transmission component. The data control unit is used to actually calculate the addition amount of the sodium hypochlorite solution, and the detection results received by the monitoring unit are sent to the data control unit in real time. After the test results are obtained, the test results are compared with the preset standard concentration values, and the start and stop of the dosing unit is controlled in real time according to the comparison results, so as to replenish the sodium hypochlorite solution in the clean water tank until the residual chlorine concentration in the clean water tank reaches the standard value, and then the dosing is stopped. In this process, the dosing rate of the dosing unit is controlled in real time according to the test values. For example, according to the maximum dosing rate of the dosing unit, the dosing rate of the dosing unit is divided into multiple gradients, and the residual chlorine concentration of the clean water tank is divided into multiple gradients. When the dosing is actually performed, the test results are compared with the divided gradients, and then the dosing unit is controlled to The sodium hypochlorite solution is added at a corresponding dosing rate. In actual application, in order to maintain the effective concentration of the generated sodium hypochlorite and to meet the addition rate of the sodium hypochlorite, the dosing unit in the present invention at least includes a sodium hypochlorite generator 1, a storage tank 2, a dosing pipe 21 and a reflux pipe 22. Before and after the addition of the sodium hypochlorite solution, the sodium hypochlorite generator 1 maintains the maximum power to continuously electrolyze the brine to generate the sodium hypochlorite solution, and guides the generated sodium hypochlorite solution to the storage tank 2 for storage. Then, according to the instruction sent by the data control unit, the dosing pipe 21 adds the hypochlorite to the clean water tank. Sodium hypochlorite solution, and in the process of long-term use, the sodium hypochlorite generator 1 is synchronously linked with the dosing pipe 21 to maintain the sodium hypochlorite in the storage tank 2 in a full load state as much as possible, so that when the demand for sodium hypochlorite solution is greater than the maximum power of the sodium hypochlorite generator 1 in the later stage, the sodium hypochlorite solution pre-stored in the storage tank 2 can be used to meet the demand for the rate of sodium hypochlorite addition. At the same time, during long-term use, the sodium hypochlorite generator 1 is started regularly, and the sodium hypochlorite solution in the storage tank 2 is extracted through the reflux pipe 22, and re-electrolyzed, thereby maintaining the effective concentration of the sodium hypochlorite solution in the storage tank 2.

[0059] The present invention detects the residual chlorine content in the clear water tank and the sodium hypochlorite concentration in the dosing pipe 21, and then controls the dosing rate and the start and stop time of the dosing unit according to the detection results, thereby realizing dynamic control of the sodium hypochlorite concentration in the tap water. At the same time, by providing a storage tank 2 and a reflux pipe 22, the burden of the sodium hypochlorite generator 1 is reduced by pre-storing the sodium hypochlorite solution, and the adjustable range of the dosing rate of the dosing unit is expanded, so that the adjustment rate of the residual chlorine content in the tap water is more flexible, making the tap water chlorine disinfection operation more convenient.

[0060] As a preferred embodiment of the present invention, a conducting pipe 23 is fixedly installed between the sodium hypochlorite generator 1 and the storage tank 2, a dosing pump is installed at one end of the conducting pipe 23 facing the sodium hypochlorite generator 1, the dosing pipe 21 is installed on the conducting pipe 23, and a solenoid valve is installed at the end of the dosing pipe 21, and the solenoid valve is used to control the flow rate of the sodium hypochlorite solution in the dosing pipe 21.

[0061] By providing the conducting pipe 23 and installing the dosing pipe 21 on the conducting pipe 23, in actual application, after the dosing unit is started, the sodium hypochlorite generator 1 electrolyzes the brine to generate a sodium hypochlorite solution. Under the extraction action of the dosing pump in the conducting pipe 23, the sodium hypochlorite solution is pumped into the conducting pipe 23 and flows into the dosing pipe 21 under the action of pressure. The solenoid valve in the dosing pipe 21 is directly electrically connected to the data control unit. Under the instruction of the data control unit, the opening degree of the solenoid valve changes in real time, thereby controlling the flow rate of the sodium hypochlorite solution flowing out of the dosing pipe 21. Since the sodium hypochlorite generator 1 maintains rated power and continues to operate after being started, when the generated sodium hypochlorite solution is greater than the dosing flow rate of the solenoid valve, the excess sodium hypochlorite solution is collected in the conducting pipe 23. The sodium hypochlorite solution in the storage tank 2 is gathered and gradually flows into the storage tank 2, so that the liquid level of the sodium hypochlorite solution in the storage tank 2 is increased, and then it flows back to the sodium hypochlorite generator 1 through the reflux pipe 22 for re-electrolysis. When the dosing flow rate of the solenoid valve is greater than the generation amount of the sodium hypochlorite generator 1, the sodium hypochlorite solution in the storage tank 2 flows back under the action of gravity, thereby maintaining a large flow rate of sodium hypochlorite addition. The setting of the conducting pipe 23 and the dosing pipe 21 not only updates the sodium hypochlorite solution in the storage tank 2 in real time when the addition rate of the sodium hypochlorite solution is slow, and maintains the effective concentration of sodium hypochlorite, but also gives priority to the sodium hypochlorite solution just generated by electrolysis when the sodium hypochlorite solution is added, so that the concentration of the sodium hypochlorite solution added to the clean water tank is relatively constant, thereby making the dynamic regulation effect of the residual chlorine in the clean water better.

[0062] As a preferred embodiment of the present invention, the dosing unit further includes a partition circulation component, which is installed inside the storage tank 2 and is used to perform partition circulation treatment on the sodium hypochlorite solution in the storage tank 2;

[0063] The partition circulation assembly includes a support frame 24, a rotating shaft 25 and a sealing ring 26;

[0064] The storage tank 2 is a cylindrical structure, and a rotating shaft 25 is fixedly mounted on the storage tank 2. The rotating shaft 25 is coaxially designed with the storage tank 2.

[0065] The support frame 24 is a frame-type structure, and the rotating shaft 25 is rotatably mounted on the support frame 24;

[0066] A sealing ring 26 is fixedly mounted on the support frame 24. The storage tank 2 is divided into a plurality of storage cavities 27 along the circumferential direction. The storage cavities 27 are open. The sealing ring 26 is rotatably sealed and connected to the storage tank 2. The sealing ring 26 is used to block the storage cavity opening.

[0067] The conducting pipe 23 and the reflux pipe 22 are both installed through the sealing ring 26 . The conducting pipe 23 is located at the lowest end of the sealing ring 26 , and the highest end of the reflux pipe 22 is located above the sodium hypochlorite generator 1 .

[0068] In order to enhance the updating and maintenance effect of the sodium hypochlorite solution in the storage tank 2, a partition circulation component is provided in the present invention. In actual application, the sodium hypochlorite generated in the sodium hypochlorite generator 1 is pumped into the conducting pipe 23 by the dosing pump. After the outflow in the dosing pipe 21 is removed, the remaining sodium hypochlorite solution flows along the conducting pipe 23 to the storage chamber 27 in the storage tank 2, and the liquid level of the sodium hypochlorite solution in the storage chamber is simultaneously raised. Since a plurality of storage chambers 27 are provided in the storage tank 2, when one of the storage chambers 27 is full, the staff manually pushes the storage tank 2 to rotate, thereby causing relative rotation between the storage chamber 27 and the sealing ring 26, so that the conducting pipe 23 is connected to another storage chamber 27, and the storage tank 2 is connected to the other storage chamber 27. The directional rotation makes the excess sodium hypochlorite fill the multiple storage chambers 27 in chronological order. Since the storage tank 2 is a cylindrical structure, as the storage tank 2 rotates, the storage chambers 27 are connected to the reflux pipe 22 one by one, so that the sodium hypochlorite solution in the storage tank 2 refluxes one by one in chronological order. By dividing the inner cavity of the storage tank 2, the sodium hypochlorite is re-electrolyzed in chronological order. As time goes by, the effective concentration of sodium hypochlorite gradually decreases. Therefore, the generated sodium hypochlorite solution is divided, refluxed, and re-electrolyzed in chronological order. Compared with mixing them together for reflux and re-electrolysis, the updating efficiency of the total concentration of the sodium hypochlorite solution in the storage tank 2 can be effectively accelerated.

[0069] As a preferred embodiment of the present invention, a sealing liner 28 is fixedly installed in the storage cavity 27, and the sealing liner 28 divides the storage cavity 27 into a liquid cavity and an air cavity. A vent hole 29 is opened in the storage cavity 27, and the vent hole 29 is conductively connected to the air cavity.

[0070] By installing a sealing liner 28 in the storage chamber 27 and separating the storage chamber 27 using the sealing liner 28, when sodium hypochlorite is filled and refluxed, the deformation effect of the sealing liner 28 can be used to separate the sodium hypochlorite solution from the air, thereby ensuring that the pressure in the storage chamber 27 is always balanced.

[0071] As a preferred embodiment of the present invention, a liquid level tube 3 is installed on the conducting tube 23 , a gravity piston 31 is installed in a sliding seal inside the liquid level tube 3 , and a water level rod 32 is fixedly installed on the gravity piston 31 .

[0072] When the generated sodium hypochlorite solution flows into the storage chamber 27, after the storage chamber 27 is filled, under the continuous pumping of the dosing pump, the hydraulic pressure in the conducting pipe 23 gradually increases. Since the liquid level pipe 3 is connected to the conducting pipe 23, the gravity piston 31 and the water level rod 32 are gradually lifted up under the push of the hydraulic pressure, which makes it easier to judge the rotation time of the storage tank 2.

[0073] As a preferred embodiment of the present invention, a toggle wheel 4 is fixedly mounted on the rotating shaft 25, and the toggle wheel 4 is located on the rising path of the water level rod 32. A ratchet mechanism 41 is jointly mounted on the support frame 24 and the rotating shaft 25, and the ratchet mechanism 41 is used to limit the rotation direction of the rotating shaft 25.

[0074] In order to further enhance the ease of use of the dosing unit, when the gravity piston 31 and the water level rod 32 rise under the hydraulic pressure, the water level rod 32 pushes the toggle wheel 4 during the rising process. When the storage chamber 27 is switched, the sodium hypochlorite solution in the liquid level tube 3 and the conducting tube 23 is filled into the new storage chamber 27, so that the hydraulic strength in the liquid level tube 3 decreases. Under the gravity of the gravity piston 31, the gravity piston 31 and the water level rod 32 drop again until the storage chamber 27 is full again. At this time, the toggle wheel 4 is pushed to rotate again, thereby causing the storage tank 2 to rotate automatically. At the same time, the ratchet mechanism 41 installed on the support frame 24 and the rotating shaft 25 allows the storage tank 2 to rotate only in one direction, thereby facilitating the filling of the storage chambers 27 one by one.

[0075] As a preferred embodiment of the present invention, a conductive drainage groove 42 and a connecting hole 43 are opened inside the sealing ring 26, and the connecting hole 43 corresponds to the opening of the storage chamber 27. The sealing ring 26 extends into the liquid level tube 3, and the sealing ring 26 has a liquid outlet 44 inside the liquid level tube 3. The liquid outlet 44 is conductively connected to the drainage groove 42, and a closing plate 45 is hingedly installed in the liquid outlet 44 through a torsion spring. In the initial state, the closing plate 45 blocks the liquid outlet 44, and the closing plate 45 is located on the descending path of the gravity piston 31.

[0076] During the unidirectional rotation of the storage tank 2, when the amount of sodium hypochlorite generated by the sodium hypochlorite generator 1 cannot meet the dosing rate, when the sodium hypochlorite solution in the storage chamber 27 corresponding to the conducting pipe 23 gradually flows back and the liquid level drops to the minimum, the liquid level in the conducting pipe 23 then drops. At this time, the gravity piston 31 presses down on the closing plate 45, thereby opening the liquid outlet 44. Since the drainage groove 42 is connected to multiple storage chambers 27 through the connecting hole 43, when the closing plate 45 is pressed down, the sodium hypochlorite solutions in multiple storage chambers 27 flow into the connecting hole 43, the drainage groove 42, and the conducting pipe 23 under the action of gravity, and then merge with the sodium hypochlorite solution generated by the sodium hypochlorite generator 1 to meet the dosing demand. It should be noted that as the difference between the dosing rate and the generation rate of the sodium hypochlorite generator 1 increases, the amount of sodium hypochlorite solution refluxed in the multiple storage chambers 27 increases, so that the proportion of pre-stored sodium hypochlorite solution in the added sodium hypochlorite solution gradually increases.

[0077] As a preferred embodiment of the present invention, a rubber plug 5 is fixedly installed in each of the connecting holes 43 , and each of the rubber plugs 5 is provided with a tapered hole, which is closed in an initial state.

[0078] The rubber plug 5 is arranged so that when the liquid outlet 44 is open, the rubber plug 5 is used to block the connecting hole 43, resulting in a small exchange amount of the sodium hypochlorite solution in the drainage groove 42 and the storage chamber 27. When the sodium hypochlorite solution in the drainage groove 42 is lost, the tapered hole of the rubber plug 5 is gradually deformed under the action of pressure, so that the sodium hypochlorite solution in the storage chamber 27 flows into the drainage groove 42, and flows into the conducting pipe 23 along the drainage groove 42 and the liquid outlet 44.

[0079] As a preferred embodiment of the present invention, the number of the drainage grooves 42 is at least two, and they correspond to the two ends of the storage cavity 27 respectively. The plurality of drainage grooves 42 are coaxially arranged, and the bottom ends of the drainage grooves 42 are conductively connected.

[0080] Since the storage chambers 27 are all fan-shaped structures and are arranged along the circumferential direction of the storage tank 2, at least two drainage grooves 42 are provided, which correspond to the two ends of the storage chamber 27 respectively. Therefore, when the storage chamber 27 rotates with the storage tank 2, the sodium hypochlorite solution in the storage chamber 27 flows into the drainage groove 42 and the conducting pipe 23 more conveniently.

[0081] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
