Description

Technical Field

[0001] This utility model relates to the field of water dechlorination technology, and in particular to a dechlorination device for drinking water. Background Technology

[0002] Drinking water refers to water used in daily human life, including urban and rural drinking water. Urban drinking water consists of residential water and public water (including water used by the service industry, catering industry, freight and postal services, and construction industry). Rural drinking water includes water used by livestock in addition to residential drinking water. Chlorine is added to drinking water mainly for disinfection and sterilization to ensure drinking water safety. Chlorine is a strong oxidizing agent that can effectively kill pathogens such as bacteria, viruses, fungi, and parasites in water. Chlorine in water forms hypochlorous acid and hypochlorite ions, which have strong oxidizing power and can destroy the cell walls and cell membranes of microorganisms, thereby killing them.

[0003] While chlorine is added to drinking water for disinfection and to ensure its safety, chlorine and its byproducts can have adverse effects on health and daily life under certain circumstances. Disinfection byproducts are secondary pollutants generated during the disinfection process due to the reaction of organic or inorganic substances with disinfectants. These mainly include trihalomethanes, haloacetic acids, and bromates, which are carcinogenic and reproductively toxic. Chlorine is irritating, and long-term exposure to chlorinated water may cause dry skin, itching, and allergies. For hair, chlorine can damage hair quality, and residual chlorine volatilizing into the air may irritate the respiratory tract, causing discomfort such as coughing and wheezing, especially for people with asthma or other respiratory diseases. Therefore, a chlorine removal device for drinking water is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4 A dechlorination device for drinking water includes a dechlorination tank 1, an inlet pipe 2 on one side of the dechlorination tank 1, an outlet pipe 3 on one side of the dechlorination tank 1, an adsorption component on the outlet pipe 3, a stirring component installed on the dechlorination tank 1, an irradiation component installed on the inner wall of the dechlorination tank 1, and an aeration component at the bottom of the dechlorination tank 1 to promote the volatilization of residual chlorine. The aeration component includes a blower 12 located outside the dechlorination tank 1, a filter box 13 connected to one side of the blower 12, an activated carbon filter plate installed inside the filter box 13, an air inlet pipe 14 connected to one side of the filter box 13, one end of the air inlet pipe 14 extending into the interior of the dechlorination tank 1, an outer ring pipe 15 and an inner ring pipe 16 connected to the air inlet pipe 14, and multiple aeration nozzles 17 installed at the top of both the outer ring pipe 15 and the inner ring pipe 16. Drinking water is then placed in the air inlet pipe. Place the air in the dechlorination tank 1, then start the blower 12 on the aeration assembly to generate airflow into the filter box 13. The filter box 13 is equipped with an activated carbon filter plate, which can effectively filter the incoming air. After filtration, the filter can be removed from the side outlet for replacement. The filtered air will enter through the air inlet pipe 14 and be transported to the outer ring pipe 15 and the inner ring pipe 16, and finally exit from multiple aeration nozzles 17. By setting two ring pipes of different sizes, an effective and uniform aeration effect can be achieved. Aeration can increase the oxygen content in the water and promote the volatilization of residual chlorine. A check valve can be installed on the air inlet pipe 14 to prevent the water inside the dechlorination tank 1 from flowing back. Alternatively, the blower 12 and the filter box 13 can be placed at a high position so that backflow water will not enter the filter box 13.

[0022] Furthermore, the irradiation assembly includes multiple mounting slots 5 formed on the inner wall of the dechlorination tank 1, with ultraviolet (UV) lamps 6 installed in the mounting slots 5. A wiring conduit 7 is provided on the outside of the dechlorination tank 1, connecting to the multiple UV lamps 6. A support column 18 is fixedly installed on the top of the mounting frame 8, and a top protective canopy 19 is fixedly installed on the support column 18. When the UV lamps 6 on the irradiation assembly are activated, a transparent lampshade with good waterproof effect is provided on the outside of the UV lamps 6. The transparent lampshade is made of quartz glass, which has a high UV transmittance. The main component of quartz glass is high-purity silicon dioxide, whose molecular structure absorbs less UV light, thus facilitating the irradiation of the water by the UV light. Ultraviolet light can accelerate the volatilization of residual chlorine. Its high energy can break the chemical bonds in residual chlorine molecules, causing them to decompose into simpler substances. Specifically, residual chlorine in water mainly exists in the form of hypochlorous acid (HClO) and hypochlorite ions (ClO-). When ultraviolet light irradiates these substances, a photochemical reaction occurs, causing hypochlorous acid and hypochlorite ions to decompose into chloride ions (Cl-) and oxygen (O). Through this reaction, residual chlorine is decomposed into chloride ions and oxygen, thereby reducing the concentration of residual chlorine in the water and accelerating its volatilization. Through this dual acceleration of volatilization, residual chlorine in drinking water can be effectively removed. The residual chlorine will volatilize from above, and the top protective canopy 19 provides effective protection from above.

[0023] Furthermore, the stirring assembly includes a mounting bracket 8 fixedly installed on the top of the dechlorination tank 1. A stirring motor 9 is fixedly installed on the mounting bracket 8. The output end of the stirring motor 9 is connected to a stirring shaft 10. Multiple stirring blades 11 are fixedly installed on the stirring shaft 10. When the stirring motor 9 on the stirring assembly is running, it drives the stirring blades 11 to rotate, slowly stirring the drinking water inside. The stirring allows the water inside to circulate, and in conjunction with aeration dechlorination and ultraviolet irradiation dechlorination, the residual chlorine in the water is removed more thoroughly and effectively.

[0024] Furthermore, the adsorption component includes an activated carbon water filter 4 installed at the end of the outlet pipe 3. When using the water in the dechlorination tank 1, the valve on the outlet pipe 3 is opened, and drinking water will flow out. The outlet pipe 3 is equipped with an activated carbon water filter 4. Activated carbon has a good adsorption capacity and can effectively adsorb residual chlorine, odors, impurities, etc. in the water, and can effectively remove residual chlorine and impurities from the water. The activated carbon water filter 4 can be any commercially available water filter. When installing, the activated carbon water filter 4 can be snapped onto the outlet pipe 3 or fixed with a pin, depending on the installation and usage.

[0025] In use: When using drinking water, place it in the dechlorination tank 1, turn on the blower 12 to generate airflow. The filtered air enters the outer ring pipe 15 and the inner ring pipe 16, and finally exits from multiple aeration nozzles 17. Aeration increases the oxygen content in the water and promotes the volatilization of residual chlorine. At the same time, turn on the ultraviolet irradiation lamp 6. The ultraviolet light accelerates the volatilization of residual chlorine. Through dual acceleration of volatilization, residual chlorine in drinking water can be effectively removed. The residual chlorine will evaporate from the top. When using the water in the dechlorination tank 1, it will flow out from the outlet pipe 3. The outlet pipe 3 is equipped with an activated carbon filter 4, which can effectively adsorb residual chlorine in the water. It is convenient to use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
