When flake soda is processed again, different methods are used to make it, and there will be some gaps in the purity of the finished product and the effect of use. Among the many methods, the purity of the product processed by the batch treatment method is relatively high. High, let's introduce the specific operation steps of this method in detail.
1. Generally, when processing, it is necessary to use the batch cooking process to produce alkaline substances in a molten state.
2. After that, the molten alkali produced is transported to the high-level tank, and some coal burning can be used at the bottom of the high-level tank to burn it for heat preservation work. As for the amount of caustic soda in the high-level tank, an overflow device needs to be used. etc. to control.
3. After that, the lye liquid is transported from the high-level tank to the arc-shaped alkali tank, and the flow rate needs to be controlled during the transportation process.
4. The molten alkali after evaporating the alkali liquor enters the arc groove after passing through the finished product separator.
5. After entering the dovetail groove on the surface of the refrigeration drum, the depth of the bottom of the drum that needs to be immersed into the arc-shaped alkali tank is about 20-25mm.
6. Then the drum rotates at a relatively slow speed, and the cooling water will slowly enter the middle of the bearing from one side of the bearing, and then spray to the inner surface of the drum to cool it, so as to ensure that the drum Has good heat transfer performance.
7. With the rotation of the drum, it will be slowly scraped off by the scraper to obtain the finished product.
