Abstract

The invention provides a double-self-suction type device for preparing purified water of hydrogen-rich water. The double-self-suction type device comprises a raw water tank, and further comprises a double-self-suction type stirrer, a U-shaped degassing mold and a purified water tank, wherein the raw water tank, a gas dissolved water tank, the U-shaped degassing mold and the purified water tank arecommunicated through a pipeline in sequence; a water pressure gauge and a water valve are arranged on a pipeline for communicating the raw water tank and the gas dissolved water tank; the gas dissolved water tank is internally provided with the double-self-suction type stirrer; a gas storage tank is further connected between the double-self-suction type stirrer and the U-shaped degassing mold inparallel. A degassing part of the double-self-suction type device for preparing the purified water of the hydrogen-rich water adopts a U-shaped degassing pipe; the U-shaped degassing pipe is connectedwith two hollow fiber membranes in series, and gas-liquid separation is carried by adopting a pumping and degassing manner; a degassing membrane with a hydrophobic property does not generate any impurity in a degassing process and a chemical reaction process does not exist; the safety and reliability of a product are ensured. Secondary degassing is formed in the U-shaped degassing pipe in a serial connection manner; meanwhile, an annular part of the U-shaped pipe reduces linear head loss of fluid energy very well and fluid can flow in the pipe at a relatively high flow speed. The flow speed of a water body can be increased and good degassing quality also can be ensued; the water treatment time is extremely shortened.

Description

technical field [0001] The invention belongs to the high-tech field of hydrogen-rich drinking water. More specifically, it relates to a device for degassing pure water to prepare pure water. Background technique [0002] Hydrogen-rich water requires two core treatments to increase the hydrogen content. One is to use a special process to increase the solubility of hydrogen in water. In addition, a pure water degassing process is required before processing and preparing hydrogen-rich water. Oxygen, nitrogen, and carbon dioxide in the water are removed to obtain pure water for the preparation of hydrogen-rich water. In this way, the oxidation of oxygen will cause the dissolved hydrogen to react with oxygen when the hydrogen molecules are dissolved in water, which will lead to a decrease in the hydrogen content of the product and affect the efficacy of the product. The quality of pure water is related to the quality of hydrogen-rich water products. As one of the core technolog...
