熔鹽法對氫氧化鉀進行加熱

發布來源:http://chungcumysontower.com    更新時間:2021-06-04 點擊數:

在之前的文章中介紹過氫氧化鉀各種方法,我們會發現,這當中都會有一個加熱的工藝,雖然方法各有個的不同,但是在加熱的過程當中,每一種方法都是通用的,但是各種方法也有優劣之分,今天我們來講一種加熱效果比較好的方法,就是使用熔鹽法進行加熱。

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、在加工的工序當中,其中的一個步驟就是對液堿進行加熱,這樣將其中的水分等蒸發出去,等蒸發到液堿的濃度合適之后,就可以進行后面的操作。
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、在使用熔鹽法之前用方式是通過使用火直接加溫鍋,所以如此煤在燃燒之后不能處理干凈,還會有很多的灰塵和粉塵等堆積在爐李阿里面和還有鍋內,從而會導致氫氧化鉀之后進行的熱傳導輸出功率低。
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、所以現在為了起到節省能耗的作用,使用的都是三鍋法,分別是加熱鍋,煮鍋和彩鍋。熔鹽加熱的裝置是一種煤基熔鹽加熱系統,從而起到控制到達濃縮器的熔鹽溫度的作用,因為高濃模塊的加工當中對于溫度也是有相應的工藝規定。
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、煤碳的熔化鹽在加熱到集中器需要的430℃的溫度之后就可以進到爐里面,然后熔鹽從高濃設備出去時溫度需要是400℃,通過熔鹽泵運輸熔鹽的整個循環系統。
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、這個時候從熔鹽爐出來的高溫煙塵就會進到燃氣蒸汽鍋爐里面,使用空預器冷掉后會繼續進入到水膜除塵器。煙塵除灰、脫硫之后就可以進到增壓風機,通過增壓風機輸送到空氣。
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.
上面介紹的就是使用熔鹽法對氫氧化鉀進行加熱的步驟,我們在加熱的過程當中需要注意,熔鹽進入集中器的溫度一定得是430攝氏度,如果溫度太低了,那么可能達不到預想的效果。
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.
