Description

Technical Field

[0001] The utility model relates to the technical field of water disinfection equipment, in particular to a water body chlorination disinfection device. Background Art

[0002] Water disinfection is a necessary treatment operation for water plants when producing tap water. It is usually done by adding disinfectants to natural water bodies to sterilize and disinfect the water bodies to improve the quality and safety of the water bodies. Chlorination disinfection is the main method currently used in tap water disinfection technology. Its function is to kill pathogenic microorganisms in the water and ensure drinking water safety. The existing method of adding tap water disinfectants is to directly mix the disinfectant into the water and mix it by the water flow, or to transport liquid disinfectants such as liquid chlorine to the pool to disinfect the water. The disinfectant diffuses with the outflow as the center of the circle, and it takes a certain amount of time to disinfect the water in the pool.

[0003] However, the traditional disinfectant addition process does not involve stirring, which results in the disinfectant being unable to quickly mix with water, resulting in a slow disinfection speed and low disinfection efficiency, which cannot meet water supply needs. At the same time, it causes uneven disinfection of water in the pool, resulting in substandard tap water quality and affecting residents' health. In addition, although adding disinfectants to flowing water can improve the mixing rate and disinfection efficiency to a certain extent, the conventional intermittent multi-point / batch addition method is affected by the concentration of the disinfectant, and the mixing concentration of the disinfectant in a large volume of water is inconsistent, which easily leads to the defect that excessive or insufficient disinfectant is added to water in different areas, affecting the water quality. Finally, the existing water disinfection process usually disinfects the water in a specific cavity by adding disinfectants in a quantitative manner. Only after the water in this part is disinfected and discharged from the specific cavity, the undisinfected water is continued to be poured in, and then the disinfectant is added for disinfection and the operation of discharge after disinfection is repeated. This batch-by-batch disinfection treatment method cannot achieve continuous operation and has low production efficiency. Utility Model Content

[0027] Example 1

[0028] The present application provides a water body chlorination disinfection device, which includes an inflatable shell 1, a water inlet pipe 2, a stepped diversion chlorination component 3, a drain pipe 4 and a premix component 5.

[0029] according to Figure 1-3In a specific embodiment shown, a water inlet pipe 2 is provided at the top of one side of the inflatable shell 1. A stepped diversion chlorination assembly 3 is provided in the shell cavity of the inflatable shell 1. The output end of the water inlet pipe 2 is inserted into the inflatable shell 1 and placed on the top of the stepped diversion chlorination assembly 3. A drain pipe 4 is also inserted on the side of the inflatable shell 1 away from the water inlet pipe 2. A premix assembly 5 capable of pre-feeding treatment in a manner of annular multi-point input of disinfectant is provided on the branch pipe body 22 of the water inlet pipe 2. The stepped diversion chlorination assembly 3 provided in the present application continuously and in a trace amount and at a high frequency inputs chlorine to the water body flowing along the step surface by outputting chlorine through a multi-stage array of micropores, thereby improving the mixing efficiency, uniformity and continuity of chlorine and avoiding the defect of uneven dispersion of intermittent dosing. The microporous chlorine discharge of the step-guiding chlorination component 3 enables the chlorine to continuously pass through the water flow layer in small quantities, so as to effectively and fully dissolve in the water flow layer, and quickly disperse in the process of the water flow being disturbed and the flow state changing, thereby improving the uniformity of mixing. The rising chlorine can produce an impact on the water flow layer to accelerate its integration rate and dispersion rate. The premix component 5 provided in the present application can be mixed with a low concentration of chlorine-containing disinfectant into the water body before chlorine disinfection to achieve preliminary disinfection treatment in advance. It can make the chlorine-containing disinfectant quickly and effectively mix into the water body by radially inputting the low concentration of chlorine-containing disinfectant at multiple points in the circumferential direction to the water body flowing in the lumen, and simultaneously carry out high-speed relative motion with the water molecules to accelerate the miscible dispersion of the disinfectant. Both the step-guiding chlorination component 3 and the premix component 5 can realize continuous and uninterrupted water body disinfection treatment by continuously supplying disinfectant to the continuously flowing water, thereby realizing the continuous operation of water body disinfection, thereby improving the production efficiency of tap water used by residents. Compared with the defects of unevenness and difficulty in mixing and dispersing the traditional batch-by-batch interval addition of disinfectant to a certain amount of water for separated disinfection, this application ensures that the entire water environment can be effectively mixed with a standard amount of disinfectant through a double continuous and uninterrupted addition of low-concentration agents, while avoiding the excessive concentration of agents in some areas and excessively high agent content, as well as the defects of low agent concentration and poor water quality in the diffusion edge area of ​​traditional diffusion disinfection, improving the rate and uniformity of agent dispersion and miscibility, improving the overall effect of sterilization and disinfection, and accelerating secondary miscibility with the water body through prefabricated low-concentration aqueous disinfectant. The dual disinfection structure of the stepped diversion chlorination component 3 and the premix component 5 improves the mixing uniformity and the accuracy of the addition amount between the disinfectant and the continuously flowing water body, realizes the continuous disinfection treatment of the water body under the continuous transportation state, and improves the disinfection efficiency and disinfection quality.
