You know a little about the production of solid potassium hydroxide. There is a heating operation, which is very important. Although the production methods are different, the heating process is the same, and the method is universal. So let's share a good example of molten salt heating.
1. In the process of processing, one of the steps is to heat the liquid alkali so that the water will evaporate out. If the concentration of the liquid alkali evaporated is appropriate, subsequent operations can be carried out.
2. Before using the molten salt method, the hot pot is directly heated by fire, and the coal cannot be cleaned after combustion. A large amount of dust and dust will accumulate in the furnace and pot, resulting in low heat conduction output power after solid potassium hydroxide.
3. So now in order to play a role in energy saving, the use methods of the three pots are heating pot, pot and color. The molten salt heating device is a thermal molten salt heating system, which can control the molten salt temperature to reach the concentrator, because there is a corresponding technical regulation of temperature in dealing with high concentration modules.
4. The molten salt of solid potassium hydroxide can be put into the furnace after being heated to 430 ℃ required by the concentrator, and it needs to be heated to 400 ℃ when coming out from the high concentration equipment. The whole molten salt circulation system is delivered by molten salt pump.
At this time, the high-temperature smoke and dust from the molten salt furnace will enter the gas and steam boiler, and will continue to enter the water film dust remover after being cooled by the air preheater. After dedusting and desulfurization, the dust can enter the booster fan, and the air can be delivered through the booster fan.
The procedure described above is to use molten salt to heat solid potassium hydroxide, which is a method we can often use and a good method. Therefore, be careful in the heating process. The temperature of molten salt entering the concentrator must be 430 ℃. If the temperature is too low, the expected effect may not be achieved.
