Description

Technical Field

[0001] This utility model belongs to the field of high-purity water production, specifically a high-purity water production and purification device. Background Technology

[0002] High-purity water refers to water with most impurities removed, such as metal ions, organic matter, and chlorine. Current high-purity water production processes require multiple treatments to obtain the final product. High-purity water has applications in various fields; the water produced by automated water purification systems in communities can be considered high-purity water for drinking. It is also widely used in the chemical industry, where many chemical reagents use it as a solvent, such as antifreeze and electronic-grade etching solutions. However, current high-purity water production processes typically involve first filtering solid impurities, then using activated carbon to adsorb organic matter and chlorine, followed by ion exchange resin to remove metal ions, and finally reverse osmosis membrane filtration to obtain the final high-purity water. However, the current step-by-step processing of activated carbon and ion exchange resin is inefficient, and the subsequent solid-liquid separation further reduces efficiency. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] A high-purity water production and purification device includes a purifier 1. An activated carbon mesh cage 2 is installed at the top of the purifier 1, and an ion exchange resin mesh cage 3 is installed at the bottom. The top of the purifier 1 is connected to an inlet pipe 4, and the bottom of the purifier 1 is connected to one end of a circulation pipe 5. A circulation pump 6 is installed on the circulation pipe 5, and the other end of the circulation pipe 5 is connected to the top of the purifier 1. The bottom of the purifier 1 is connected to an outlet pipe 7, and an outlet valve 8 and an outlet pump 9 are installed on the outlet pipe 7. In operation, a specified amount of water is added to the purifier 1 through the inlet pipe 4. Then, the circulation pump 6 is turned on, causing the water in the purifier 1 to flow upwards along the circulation pipe 5. This upward flow of water passes sequentially through the activated carbon mesh cage 2 and the ion exchange resin mesh cage 3, making contact with the activated carbon and ion exchange resin to further improve their adsorption efficiency of impurities in the water. After treatment, the circulation pump 6 is turned off, and then the outlet valve 8 and the outlet pump 9 are turned on to send the water along the outlet pipe 7 into a reverse osmosis system for further treatment.

[0016] Specifically, in this embodiment, an ultrasonic oscillator 10 is installed inside the side wall connecting the activated carbon mesh cage 2 and the ion exchange resin mesh cage 3 to the purifier 1. In this invention, the ultrasonic oscillator 10 can drive the activated carbon and ion exchange resin to vibrate, thereby improving their adsorption efficiency for impurities in water.

[0017] Specifically, since the activated carbon and ion exchange resin in the activated carbon mesh cage 2 and ion exchange resin mesh cage 3 need to be periodically recycled when they adsorb to a certain extent to ensure the removal efficiency of impurities in the water, the top of the activated carbon mesh cage 2 and ion exchange resin mesh cage 3 in this embodiment is connected to the inclined feed pipe 11. The feed pipe 11 is equipped with a feed valve 12 and a feed screw conveyor 13. The bottom of the activated carbon mesh cage 2 and ion exchange resin mesh cage 3 is connected to the inclined discharge pipe 14. The discharge pipe 14 is equipped with a discharge valve 15 and a discharge screw conveyor 16. In this invention, activated carbon and ion exchange resin are fed into the activated carbon mesh cage 2 and ion exchange resin mesh cage 3 through the feed pipe 11. Simultaneously, the feed screw conveyor 13 prevents blockage of the feed pipe 11 during feeding, and the feed valve 12 prevents water from flowing out through the feed pipe 11. When the activated carbon and ion exchange resin need to be recycled and replaced after a period of use, the discharge valve 15 and the discharge screw conveyor 16 are opened to discharge the activated carbon and ion exchange resin. At the same time, the ultrasonic vibrator 10 can be activated during the discharge process to prevent the activated carbon and ion exchange resin adhering to the activated carbon mesh cage 2 and ion exchange resin mesh cage 3 from being difficult to discharge. Furthermore, water can be added through the water inlet pipe 4 during the discharge process; under the action of the ultrasonic vibrator 10, the activated carbon and ion exchange resin will be quickly discharged with the water, improving operational efficiency and ease of use.

[0018] Furthermore, in this embodiment, a filter screen 17 is provided at the connection between the water outlet pipe 7 and the purifier 1. In this invention, the filter screen 17 can prevent broken activated carbon or ion exchange resin powder from being discharged with the water, ensuring the purity of the discharged water.

[0019] Furthermore, in this embodiment, the bottom of the purifier 1 is connected to a cleaning drain pipe 18, and a cleaning drain valve 19 and a cleaning drain pump 20 are installed on the cleaning drain pipe 18. In this invention, after the activated carbon and ion exchange resin are discharged and before replacing them with new activated carbon and ion exchange resin, water is added through the water inlet pipe 4 and the purifier 1 is cleaned under the action of the ultrasonic vibrator 10. After cleaning, the cleaning drain valve 19 and the cleaning drain pump 20 are opened to discharge the cleaning water, which can also carry away the broken activated carbon or ion exchange resin powder. After cleaning, new activated carbon and ion exchange resin can be replaced to ensure the cleanliness of the purifier 1 and the purity of the treated water.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
