Potassium hydroxide needs to be heated in the process of preparation. During preparation, the liquid alkali should be evaporated and concentrated to a certain concentration before subsequent processing. But do you know how it's heated? Let's give you a specific explanation.
The traditional pot method directly uses fire to heat the alkali pot, resulting in incomplete coal combustion, ash deposition in furnace and solid alkali pot, and low heat transfer capacity. In order to save energy, three pot method is usually used; They are preheating pot, cooking pot and color mixing pot.
Potassium hydroxide molten salt heating device is a molten salt heating system with coal as fuel, which is used to control the molten salt temperature reaching the concentrator to meet the process requirements of high concentration device. The molten salt with coal as fuel enters the furnace at 430 ℃ required by the concentrator. When the molten salt leaves the high concentration device, the temperature is 400 ℃, and the molten salt flows into the molten salt tank by gravity, and then the molten salt is transported by the molten salt pump to circulate the whole molten salt system.
The above content is the heating method of potassium hydroxide, I believe you have a further understanding. In addition, the high temperature gas from the molten salt furnace enters the steam generator, enters the water film dust collector after cooling by the air preheater, enters the water film induced draft fan after desulfurization, and is led into the chimney and discharged into the atmosphere through the induced draft fan.
