The recrystallized soda ash has fine crystals； Inadequate washing; uneven distribution of washing water ； The vacuum level is too low ； The wash water contains a high level of chloride ions
Answer: ① The recrystallized soda ash has fine crystals； ②Inadequate washing; uneven distribution of washing water ； ③The vacuum level is too low ； ④The wash water contains a high level of chloride ions.
1. Fine crystallization of sodium bicarbonate
2. Insufficient washing water; uneven distribution of washing water
3. Too low vacuum level
4. High chloride ion content in the washing water
2. Insufficient washing water; uneven distribution of washing water
3. Too low vacuum level
4. High chloride ion content in the washing water

The chlorine ion content in the wash water is too high. 3. The particles of sodium bicarbonate are too small. 4. The salt content in the ammonia brine is excessive; that is, β is too small. These are some of my thoughts; please feel free to provide your feedback.
1. The recrystallized soda ash particles are fine. 2. Insufficient rinsing; uneven distribution of rinse water. 3. The vacuum level is too low. 4. The wash water has a high chloride ion content.

The amount of water used for washing is too little； The wash water contains too high a level of chloride ions ； The sodium bicarbonate particles are too small ； There is too much salt content in the ammonia brine; that is, β is too small. 1# steinback
