[Soda ash knowledge] Daily question (166) 2010.3.28

Why does heavy alkali filter cake need to be washed? Why should we control the washing water volume? How can I reduce the amount of washing water used? Because the ammonium chloride mother liquor contained in heavy alkali will react to generate sodium chloride during the calcination process, affecting the quality of soda ash ； The amount of washing water will affect the total volume of the system and the quality of soda ash, so the amount of washing water must be controlled. ； Methods to control the amount of washing water: reduce the chloride ion content in the washing water and make the sodium bicarbonate crystals coarser

1. In order to ensure the quality of soda ash products, the heavy alkali filter cake must be washed； 2. Too much or too little washing water is closely related to the entire soda ash production. Too little washing water cannot guarantee product quality. ； Washing water that is too high will cause the material liquid in the entire system to expand. ； 3. Ways to reduce the amount of washing water are:: Ensure the crystallization quality of heavy alkali and uniform particle size distribution ； Washing water quality including temperature, hardness, viscosity and chemical composition must be guaranteed ； The structural size and capacity of the filter should be balanced with the production load.

Why does heavy alkali filter cake need to be washed? Why should we control the washing water volume? How can I reduce the amount of washing water used? Answer: In order to ensure the quality of soda ash products, the heavy alkali filter cake must be washed. Too little or too much washing water is closely related to the entire soda ash production. If the washing water is too little, product quality cannot be guaranteed; if the washing water is too high, the material liquid in the entire system will expand. The main ways to reduce the amount of washing water are as follows:: Ensure the crystallization quality of heavy alkali and the uniform distribution of particle size; the quality of washing water including temperature, hardness, viscosity, chemical composition, etc. must be ensured; the structural size and capacity of the alkali filter machine must be balanced with the production load.

In order to reduce the water content of heavy alkali, polyoxyethylene alkyl ether, or its derivatives, or its compounds are added to the filter washing liquid to wash the heavy alkali filter cake, thereby saving the amount of washing liquid, reducing energy consumption, improving the operation of the next process and increasing the capacity of the calciner. It is also beneficial to low-salt alkali production.

The purpose of filter cake washing is to remove sodium chloride entrained in heavy alkali. To improve product quality, the amount of washing water controlled is to reduce the expansion of mother liquor, reduce consumption, reduce waste mother liquor and improve crystal quality. A new filter is selected, a uniform washing water distributor is used, and high-quality washing water is used.
