Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, specifically to an electrolytic chlorination supplementation system and equipment. Background Technology
[0002] Secondary water supply in residential communities mainly relies on sodium chlorate disinfection added to tap water before it leaves the treatment plant. However, residual chlorine levels are low in communities at the end of the pipe network or in areas with older water ages, increasing the risk of microbial growth and secondary contamination. Electrolytic chlorination equipment is a water treatment device used for secondary water supply disinfection, widely applied in water tanks in residential communities, schools, large shopping malls, hospitals, office buildings, hotels, and other places.
[0003] The main problems with existing electrolytic chlorine supplementation equipment, which uses sodium hypochlorite solution of a certain concentration for disinfection, are that the amount of chlorine added is difficult to control, the effective chlorine decreases significantly with long-term storage, and a large amount of chlorate is produced. Long-term use may lead to excessive chlorate levels. Commercial sodium hypochlorite solution has a high concentration, so the dosage is low, which can easily cause uneven mixing and result in insufficient or excessive residual chlorine.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0031] This utility model provides an electrolytic chlorine supplementation system, such as... Figures 1 to 3 As shown, it includes: a salt dissolving tank 100 for dissolving table salt into brine; the salt dissolving tank 100 is connected to a dilute salt tank 200 via a first pipe 01; the brine in the salt dissolving tank 100, after dilution, is transported to the dilute salt tank 200 via the first pipe 01; the dilute salt tank 200 is connected to an electrolyzer 300 via a second pipe 02; a brine pump 400 is installed on the second pipe 02; the electrolyzer 300 is connected to a sodium hypochlorite tank 500 via a third pipe 03; the brine pump 400 transports the brine in the dilute salt tank 200 to the electrolyzer 300 via the second pipe 02 for electrolysis; the sodium hypochlorite solution produced by the electrolyzer 300 is transported to the sodium hypochlorite tank 500 via the third pipe 03; the sodium hypochlorite tank 500 is connected to a fourth pipe 04. The system includes an ejector 600, a chlorination pump 700 mounted on the fourth pipe 04, a fifth pipe 05 connected to one end of the ejector 600, and a sixth pipe 06 connected to the other end of both the fifth and sixth pipes 05 and 06. A dosing pump 900 is mounted on the fifth pipe 05, and a pipe mixer 1000 is mounted on the sixth pipe 06. The sodium hypochlorite solution in the sodium hypochlorite tank 500 is diluted by the ejector 600 and then transported to the pipe mixer 1000. The dosing pump 900 pumps the liquid in the water tank 800 through the fifth pipe 05 to the pipe mixer 1000, where it is mixed and diluted with the sodium hypochlorite solution. The diluted sodium hypochlorite solution is then transported to the water tank 800 through the sixth pipe 06.
[0032] This application uses solid salt to prepare sodium hypochlorite solution by electrolyzing the brine. The solid salt is dissolved and diluted to a 2%-3% dilute brine solution, which is then electrolyzed in an electrolyzer 300 to produce a low-concentration sodium hypochlorite solution of 4000-6000 ppm. The produced disinfectant is stored in a temporary sodium hypochlorite tank 500, which has a volume sufficient for 12 hours of use. The storage time from production to use of the disinfectant does not exceed 24 hours, completely avoiding the problems of effective chlorine decomposition and high chlorate content that occur when the disinfectant is left to stand.
[0033] The produced disinfectant solution is diluted by a 600 jet injector to a sodium hypochlorite concentration below 2 ppm. It is then further mixed by a 1000-liter pipeline mixer, resulting in a uniform sodium hypochlorite disinfectant solution with a concentration below 2 ppm (2 ppm is the maximum residual chlorine value stipulated by the drinking water hygiene standards). This solution then enters the water tank or pressurized pipeline. Due to the large volume of the diluted disinfectant, it mixes quickly and evenly with the water, ensuring comprehensive, long-lasting, safe, and stable disinfection and chlorination of the water, tank, and pipelines. This guarantees that the water supplied to users meets the "Drinking Water Hygiene Standards." The system has an absolute installation guarantee, ensuring that there will be no residual chlorine exceeding the standard or other chlorine disinfection risks at any time.
[0034] This application offers multiple dispensing modes:
[0035] 1. Chlorine can be precisely replenished based on the water tank's volume and residual chlorine monitoring to ensure that the residual chlorine in the water tank is maintained at a reasonable level and to prevent the growth of microorganisms in the water tank.
[0036] 2. Residual chlorine and flow rate mixed control: By detecting the residual chlorine in the water tank and the residual chlorine and flow rate of the tap water delivered to the water tank, the dosage is calculated based on the flow rate and residual chlorine, and the chlorine dosage is automatically controlled to ensure that the residual chlorine meets the standard.
[0037] 3. Chlorine supplementation in pressurized pipelines: When the water in the pipes stays for too long, the residual chlorine does not meet the requirements. At this time, the secondary water supply system needs to deliver tap water to the user's home. Chlorine supplementation is carried out at the front end of the pressurized pump. By monitoring the residual chlorine and the flow rate of the water supply pump in real time, the amount of chlorine added is calculated and adjusted in real time to ensure that the residual chlorine meets the standard and is maintained at a reasonable level.
[0038] In specific implementation, a flow meter 1001 is installed on the fifth pipe 05, and the flow meter 1001 is located between the dosing pump 900 and the ejector 600.
[0039] This application also includes an alarm device. When the dilution water flow rate measured by the flow meter 1001 is insufficient to dilute the disinfectant to below 2 ppm, the system will automatically alarm and will not add chlorine.
[0040] In a specific implementation, a first dilution valve 1002 for controlling the flow rate of liquid in the pipeline is provided on the fifth pipeline 05. The first dilution valve 1002 is located between the dosing pump 900 and the flow meter 1001.
[0041] In specific implementation, a hydrogen discharge port 1003 is provided on the third pipe 03, and the hydrogen discharge port 1003 is located at the top of the third pipe 03.
[0042] In a specific implementation, a first back pressure valve 1004 for controlling the liquid pressure inside the second pipeline 02 is provided on the second pipeline 02, and the first back pressure valve 1004 is located between the brine pump 400 and the electrolyzer 300; a second back pressure valve 1005 for controlling the liquid pressure inside the fourth pipeline 04 is provided on the fourth pipeline 04, and the second back pressure valve 1005 is located between the chlorination pump 700 and the ejector 600.
[0043] In specific implementation, the top of the salt dissolving tank 100 is provided with an overflow pipe 1006, and the outlet of the overflow pipe 1006 is located directly above the dilute salt tank 200.

Figure 5 As shown, it includes the aforementioned electrolytic chlorine replenishment system, which is installed inside a housing 1010. A touchscreen 1011 is installed on the housing 1010. The device size has been significantly reduced, with the compressed device dimensions being only 900*500*950mm, equivalent to the size of a small washing machine. Therefore, it is more suitable for use in secondary disinfection systems that are numerous, have small equipment rooms, and require unattended operation.
[0048] This equipment is small in size, highly integrated, and provides precise dosing concentration. It is safe and efficient in its dosing method. Through automatic residual chlorine monitoring and intelligent dosing, it can effectively solve the problem of low residual chlorine in secondary water supply tanks and water supply networks. At the same time, it can also be used for disinfection in various places such as hospitals, schools, swimming pools, and hotels.
