In the previous article introduced various methods of potassium hydroxide, we will find that there will be a heating process, although there are different methods, but in the heating process, each method is universal, but various methods also have advantages and disadvantages. Today, we will talk about a better heating method, that is, using molten salt method for heating.

1、在加工的工序当中，其中的一个步骤就是对液碱进行加热，这样将其中的水分等蒸发出去，等蒸发到液碱的浓度合适之后，就可以进行后面的操作。

1. In the process of processing, one of the steps is to heat the liquid alkali, so that the water in it can be evaporated. After the concentration of the liquid alkali is appropriate, the following operation can be carried out.

2、在使用熔盐法之前用方式是通过使用火直接加温锅，所以如此煤在燃烧之后不能处理干净，还会有很多的灰尘和粉尘等堆积在炉李阿里面和还有锅内，从而会导致氢氧化钾之后进行的热传导输出功率低。

2. Before using the molten salt method, the way is to use fire to heat the pot directly, so the coal can not be cleaned after combustion, and there will be a lot of dust and dust accumulated in the furnace and pot, which will lead to low output power of heat conduction after potassium hydroxide.

3、所以现在为了起到节省能耗的作用，使用的都是三锅法，分别是加热锅，煮锅和彩锅。熔盐加热的装置是一种煤基熔盐加热系统，从而起到控制到达浓缩器的熔盐温度的作用，因为高浓模块的加工当中对于温度也是有相应的工艺规定。

3. So now in order to save energy, the three pot method is used, which is heating pot, boiling pot and color pot. The molten salt heating device is a coal based molten salt heating system, which can control the molten salt temperature to the concentrator, because there are corresponding process regulations for the temperature in the processing of high concentration module.

4、煤碳的熔化盐在加热到集中器需要的430℃的温度之后就可以进到炉里面，然后熔盐从高浓设备出去时温度需要是400℃，通过熔盐泵运输熔盐的整个循环系统。

4. The molten salt of coal can enter into the furnace after being heated to 430 ℃ required by the concentrator, and then the temperature of molten salt when it goes out from the high concentration equipment needs to be 400 ℃. The molten salt is transported through the whole circulation system of molten salt pump.

5、这个时候从熔盐炉出来的高温烟尘就会进到燃气蒸汽锅炉里面，使用空预器冷掉后会继续进入到水膜除尘器。烟尘除灰、脱硫之后就可以进到增压风机，通过增压风机输送到空气。

5. At this time, the high-temperature dust from the molten salt furnace will enter the gas-fired steam boiler, and will continue to enter the water film dust collector after being cooled by the air preheater. After ash removal and desulfurization, the dust can be sent to the booster fan, and then transported to the air through the booster fan.

上面介绍的就是使用熔盐法对氢氧化钾进行加热的步骤，我们在加热的过程当中需要注意，熔盐进入集中器的温度一定得是430摄氏度，如果温度太低了，那么可能达不到预想的效果。

The above is the process of heating potassium hydroxide by molten salt method. We need to pay attention to the temperature of molten salt entering the concentrator must be 430 ℃. If the temperature is too low, the expected effect may not be achieved.
