In the production process of potassium hydroxide, heating should be carried out. The liquid alkali should be evaporated and concentrated to a certain concentration before subsequent processing. But do you know how it is heated? Let's give you a specific explanation.

傳統(tǒng)的鍋式法直接用火加熱堿鍋，煤焚燒不完全，灰分及煤煙垢積存在爐膛及固堿鍋上，傳熱功率低。為了節(jié)約能源，通常選用三連鍋法；即預(yù)熱鍋、蒸煮鍋和調(diào)色鍋。

In the traditional pot method, the alkali pot is heated directly by fire. The combustion of coal is incomplete, the ash and soot scale are deposited in the furnace and the solid alkali pot, and the heat transfer power is low. In order to save energy, triple pot method is usually used, i.e. preheating pot, cooking pot and color mixing pot.

氫氧化鉀熔鹽加熱單元是以煤為燃料的熔鹽加熱體系，該體系用來操控抵達(dá)濃縮器的熔鹽的溫度，以滿足高濃度單元的工藝需求。以煤為燃料的熔鹽進(jìn)入爐子，溫度為濃縮器所需的溫度430℃。熔鹽脫離高濃度單元時的溫度為400℃，經(jīng)過重力流入熔鹽罐，然后用熔鹽泵運(yùn)送熔鹽來循環(huán)整個熔鹽體系。

Potassium hydroxide molten salt heating unit is a molten salt heating system using coal as fuel. The system is used to control the temperature of molten salt arriving at the concentrator to meet the process requirements of high concentration unit. The molten salt with coal as fuel enters the furnace at a temperature of 430 ℃ required by the concentrator. When the molten salt is separated from the high concentration unit, the temperature is 400 ℃ and flows into the molten salt tank by gravity, and then the molten salt is transported by the molten salt pump to cycle the whole molten salt system.

上述的內(nèi)容就是氫氧化鉀的加熱方式的內(nèi)容，大家都已經(jīng)有更進(jìn)一步的學(xué)習(xí)了，另外，它從熔鹽爐出來的高溫氣進(jìn)入蒸汽發(fā)生器，再經(jīng)過空氣預(yù)熱器降溫后進(jìn)入水膜除塵器，脫硫后進(jìn)入引風(fēng)機(jī)，經(jīng)引風(fēng)機(jī)引進(jìn)煙囪排大氣。想了解更多資訊，請繼續(xù)關(guān)注我們：http://www.yiqijieneng.cn

The above content is the content of the heating method of potassium hydroxide. We have learned more about it. In addition, the high-temperature gas from the molten salt furnace enters the steam generator, and then enters the water film dust collector after cooling by the air preheater. After desulfurization, it enters the induced draft fan, which is introduced into the chimney and discharged to the atmosphere through the induced draft fan.
