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.
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.
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.
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.
