In the process of production, potassium hydroxide needs to be heated. In the process of production, 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 talk about it in detail.

　　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。

　　The traditional boiler method uses fire to heat the alkali boiler directly. The coal combustion is incomplete. The ash and soot deposit in the furnace and the alkali fixing boiler, so the heat transfer power is low. In order to save energy, the three connected pot method is usually used, that is, 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(shí)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(gè)熔鹽體系。

　　Potassium hydroxide molten salt heating unit is a coal-fired molten salt heating system, which is used to control the temperature of molten salt reaching the concentrator to meet the process requirements of high concentration unit. The molten salt with coal as fuel enters the furnace, and the temperature is 430 ℃ required by the concentrator. When the molten salt is separated from the high concentration unit, the temperature is 400 ℃, which flows into the molten salt tank through gravity, and then the molten salt is transported by the molten salt pump to circulate 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。

　　The above content is the content of the heating method of potassium hydroxide, which has been further studied. In addition, the high-temperature gas from the molten salt furnace enters the steam generator, then enters the water film dust collector after cooling through the air preheater, enters the induced draft fan after desulfurization, and then enters the chimney through the induced draft fan to exhaust to the atmosphere.
