Description

Technical Field

[0001] The utility model belongs to the technical field of alkaline sewage storage, and in particular relates to an alkaline sewage storage device for producing hydrogen by alkaline water electrolysis. Background Art

[0002] Acid-base wastewater is the most common type of wastewater treatment. Acidic wastewater mainly comes from steel mills, chemical plants, dye plants, electroplating plants and mines. Wastewater treatment should focus on the treatment of various harmful substances or heavy metal salts. The mass fraction of acid in wastewater treatment varies greatly, with the lowest being less than 1% and the highest being greater than 10%. Alkaline wastewater mainly comes from printing and dyeing plants, leather factories, paper mills, refineries, etc. When treating wastewater, organic or inorganic alkalis will be encountered, and the mass fraction of alkalis may be higher than 5% and lower than 1%. In addition to acids and alkalis, acid-base wastewater often contains acid salts, basic salts and other inorganic and organic substances. When electrolyzing water to produce hydrogen, alkaline wastewater needs to be stored and treated using a storage device so that the alkaline wastewater meets the processing requirements.

[0003] After searching the Chinese patent "An Inorganic Chemical Experiment Wastewater Treatment Device", the announcement number is "CN217173314U". This device uses a stirring motor to drive the stirring shaft, and the stirring shaft drives the stirring blades to stir, which improves the reaction efficiency. The reaction progress can be observed in real time through the reaction observation window, and observed through the pH meter. When the reaction reaches a dischargeable pH value, it can be discharged from the drain pipe. It is convenient for treating the sewage of inorganic chemical experiments and observing the treatment process. It can react and treat acidic sewage and alkaline sewage, and the treated liquid with a dischargeable pH value can be obtained after the reaction. The treatment effect is good, and the device is easy to move and suitable for various scenarios. However, when electrolyzing water to produce hydrogen in alkaline sewage, the cleaning effect of alkaline sewage is not ideal, and it is not convenient to effectively treat the impurities and pH value in the alkaline sewage, which reduces the electrolysis efficiency and hydrogen production purity of alkaline sewage hydrogen production.
