The recrystallized soda ash particles are fine, and the filter screen is clogged； The filter screen hasn’t been thoroughly cleaned for a long time; the blowing pressure and vacuum level are insufficient; the calcium and magnesium impurities in the alkali solution entering the wash water are excessively high
1. The recrystallized soda ash particles are fine, and the filter screen is clogged； 2. The filter screen hasn’t been thoroughly washed for a long time ； 3. Insufficient blowing pressure and vacuum degree ； 4. The calcium and magnesium impurities in the lye entering the washing water are excessively high.
1. The heavy alkali crystals are fine, and the filter screen is clogged. 2. The filter screen has not been thoroughly cleaned for a long time. 3. The blowing pressure and vacuum level are insufficient. 4. The levels of calcium and magnesium impurities in the alkali solution that enters the washing water are too high

Answer: 1. The sodium bicarbonate crystals are fine, causing blockages in the filter screen. 2. The filter screen has not been thoroughly washed for a long time. 3. The blowing pressure and vacuum level are insufficient. 4. The calcium and magnesium impurities in the sodium bicarbonate solution entering the wash water are excessively high

Reasons for alkali splashing in the alkali tank of the alkali filter and the formation of a thin layer of alkali on the filter drum: air entrainment in the discharged alkali solution, poor crystallization, and low vacuum level
1. The sodium bicarbonate crystals are fine in size, and the filter screen is clogged; 2. The filter screen has not been thoroughly washed for a long time; 3. The blowing pressure and vacuum level are insufficient; 4. The calcium and magnesium impurities in the sodium bicarbonate solution entering the wash water are excessively high
