在化学工业中,氢氧化钾的常见方法生产隔膜电解方法,汞,离子膜电解的方法,如三、当我们选择水银电解生产,风险比较高,因为水星属于重金属,有很多毒性,操作时必须正确规范操作。下面小编将介绍电解汞氢氧化钾的生产工艺，具体如下。
In the chemical industry, the common methods of potassium hydroxide production are diaphragm electrolysis, mercury, and ion-exchange membrane electrolysis. For example, when we choose mercury electrolysis production, the risk is relatively high, because Mercury is a heavy metal, which has a lot of toxicity, so we must correctly regulate the operation. The following small edition will introduce the production process of electrolytic mercury potassium hydroxide, as follows.
(1)氯化钾溶液的净化:
(1) purification of potassium chloride solution:
原料盐浴氯化钾的融化,并添加钾硬质合金、氯化钡杂质,如钙、镁、硫酸,然后进入沉降器,上层清液溢出,并使用砂滤器过滤略微悬浮固体中和槽,用盐酸酸化成盐贮水箱、泵后盐水预热设备将发挥高盐水箱、盐水进入电解槽后汞。澄清罐底的盐泥，过滤并循环利用盐水。
Melt the potassium chloride in the salt bath of the raw material, add the potassium carbide and barium chloride to remove the impurities, such as calcium, magnesium and sulfuric acid, then enter the settler, the upper clear liquid overflows, and use the sand filter to filter the slightly suspended solid neutralization tank, acidify the hydrochloric acid into the salt storage tank, pump the salt water pre heating equipment to play the role of high salt water tank and the mercury after the salt water enters the electrolytic tank. Clear the salt mud at the bottom of the tank, filter and recycle the salt water.
(2)电解:
(2) electrolysis:
汞电解槽分为电解室和泵室两部分。在电解室中，石墨或金属用作正极，水银用作负极。通电后产生的氯气送氯气干燥过程。大多数未反应的氯化钾在新鲜卤水中处理:返回卤水工艺。在萃取室中，钾泵与末端的水发生反应，形成氢氧化钾溶液，并流入电解液储存罐。由抽氢室产生的氢被送到氢站。
The mercury cell is divided into two parts: electrolysis chamber and pump chamber. In the cell, graphite or metal is used as the positive electrode and mercury as the negative electrode. The chlorine generated after power on is sent to the chlorine drying process. Most unreacted potassium chloride is treated in fresh brine: return to brine process. In the extraction chamber, the potassium pump reacts with the water at the end to form potassium hydroxide solution and flows into the electrolyte storage tank. The hydrogen produced by the hydrogen extraction chamber is sent to the hydrogen station.
(3)坚实的基础:
(3) solid foundation:
由汞电解槽电解泵房生产的含koh 45-50%的碱液，经碱液沸腾制取固体碱或经成膜机理制取产品。
The alkaline solution containing 45-50% KOH produced by the electrolysis pump house of the mercury cell is boiled to produce solid alkali or the product is produced by the film-forming mechanism.
上述电解汞法一般可以产生液碱和固体碱这两种形式的氢氧化钾成品，它们可以使用和销售，效益会更高，所以现在也得到了更频繁的应用。对于不同的生产方式的选择，我们可以综合考虑成品的质量、生产成本、设备成本等方面，希望您能有所了解。
The above-mentioned electrolytic mercury method can generally produce liquid alkali and solid alkali, which are two forms of potassium hydroxide products. They can be used and sold, and their benefits will be higher, so now they are also more frequently used. For the selection of different production methods, we can comprehensively consider the quality of finished products, production costs, equipment costs and other aspects, and hope you can understand.
