Description

Technical Field

[0001] The invention belongs to the field of intelligent control of sodium hypochlorite addition, and in particular relates to an intelligent sodium hypochlorite addition system based on Internet of Things control. Background Art

[0002] As people's living standards continue to improve, people are more and more concerned about the cleanliness of water, because only clean water can be drunk healthily. Drinking water safety and health has always been a major pain point in people's lives. With the development of technology, the Internet of Things technology has gradually been introduced into the chlorination and disinfection system of water plants, so that the Internet of Things technology can be integrated and applied with the existing water plant chlorination system to achieve fully automatic control of the water plant's dosing process.

[0003] Among them, sodium hypochlorite is widely used for the disinfection of drinking water and wastewater. Adding sodium hypochlorite to water not only has many advantages of traditional chlorine disinfection, but also has many advantages that cannot be replaced by other disinfectants. In addition to its strong bactericidal ability, it also has excellent oxidizing properties, which can not only inactivate bacteria and viruses in water, but also oxidize organic matter in water. In addition, the aromatic hypochlorite ions produced by hypochlorous acid during sterilization can change the bad odor formed by the presence of organic matter, and have good water regulation function.

[0004] For example, the prior art proposes a smart water management system based on the Internet of Things with publication number CN206172908U. The present invention proposes a smart water management system based on the Internet of Things, which installs a smart water system on the top surface of a production box, controls the stirring motor, pH meter, flow meter and sodium hypochlorite dispenser in the production box through the smart water system, and can conveniently control the disinfection system through the smart water system to achieve full automation control of the disinfection system, realize smart water management, and solve the problem of inconvenient water disinfection management in the prior art.

[0005] However, the above-mentioned smart water management system based on the Internet of Things still has the following problems: in actual use, during the disinfection and addition process of sodium hypochlorite, due to its excellent bactericidal ability, it is often difficult to ensure that its concentration meets the standard during the addition process, and multiple measurements are required. The addition time of sodium hypochlorite will be delayed during the measurement process, affecting the normal disinfection effect; and during the addition process, the current equipment operation status data is not monitored, resulting in the equipment being unable to continue the addition work when the sodium hypochlorite concentration reaches the set value, thereby affecting the effluent water quality and ultimately affecting the normal progress of its overall work.

[0034] The control terminal includes an intelligent device interface and a sodium hypochlorite generating device interface which are interconnected.

[0035] The intelligent device interface is connected to the data analysis module via a network cable and is used to interact with the data analysis module and execute instructions issued by the data analysis module; the sodium hypochlorite generating device interface is connected to the sodium hypochlorite generator and is used to control the sodium hypochlorite generator.

[0038] The intelligent sodium hypochlorite dosing system is used in the water treatment process. The treatment method of the intelligent sodium hypochlorite dosing system is:

[0039] Step 1: Analysis conditions: Determine the setting standard value and analysis mode, where the setting standard value includes the dosage concentration, dosage and analysis mode: only dosage concentration, only dosage and both dosage and concentration; real-time water quality data includes real-time turbidity value, real-time chlorine content and salt content; standard values ​​include: base content, chlorine content, turbidity value and current value; at the same time, determine the turbidity value setting interval t of the turbidity sensor (this solution takes t as 60s), the difference K between the standard value and the current value and the maximum value m. The standard value and the current value are the comparison results of the real-time data and the setting data. The current value includes the dosage concentration value and the dosage.

[0040] Step 2: Obtain water quality information;

[0041] Step 2 is specifically as follows: turn on the sodium hypochlorite generator and the turbidity sensor connected to the sodium hypochlorite generator, and the turbidity sensor measures the water outlet; and transmits the measured real-time data from the data transmission module to the data receiving storage unit. At the same time, the control terminal transmits the dosage concentration, dosage coefficient, current value and equipment operation status to the data receiving storage unit. The data analysis unit analyzes the signal received by the data receiving storage unit to obtain real-time water quality data. The data analysis unit analyzes the acquired real-time data according to the analysis mode.

[0042] Step 3: Analyze water quality data to obtain dosage and concentration;

[0043] The data analysis module first compares the real-time data received by the data receiving and storage unit with the historical data to obtain the real-time water quality data, and obtains the salt base amount through the dosing formula, and determines whether the salt base amount exceeds the maximum amount. If it does not exceed, the dosage is executed according to the standard value. If it exceeds the maximum amount, the dosage coefficient in the current value is reduced to 0, that is, no dosage is executed;

[0044] Step 4: Analyze the current value:

[0045] Obtain the current water sample turbidity value of the current value and compare it with the standard turbidity value. If the current water sample turbidity value in the current value is less than the standard turbidity value, no instruction is executed. If the current water sample turbidity value in the current value is greater than the standard turbidity value, proceed to step five.

[0046] Step 5: Control the device and the current value, specifically: connect the sodium hypochlorite generator connection unit to the sodium hypochlorite generator to start the sodium hypochlorite generator, and send an execution instruction of the addition concentration through the intelligent device control unit, then obtain the real-time turbidity value through the intelligent device control unit and generate the current value.

[0047] The dosage coefficient is obtained by obtaining the turbidity value measured by the turbidity sensor, and obtaining the dosage coefficient a through the dosage coefficient formula: a / (100-a), where a is the turbidity value, the dosage coefficient is a, and the dosage concentration is obtained through the formula: b*c / a, where b is the dosage concentration, a is the turbidity value, and c is the base amount.

[0048] In actual work, the difference K between the standard value and the current value is used to determine whether to send the corresponding instruction. If K is greater than the preset value, the current value cannot meet the standard value, and the sodium hypochlorite dosage coefficient needs to be adjusted and the dosage concentration needs to be executed. If K is less than the preset value, the current value can meet the standard value, and no instruction is executed; the maximum amount m is used to control the maximum dosage of the sodium hypochlorite generator. The maximum amount m is the maximum value when the dosage coefficient is 100. The maximum amount needs to be observed in real time to avoid exceeding the maximum amount m and affecting the water quality.
