Embodiment 1
[0012] Example 1. A method for separating crystal slurry in the production process of soda ash. After sodium bicarbonate crystallization is synthesized in a carbonization tower, the crystal slurry is taken out from the carbonization tower and introduced into a hydrocyclone for hydrocyclone separation. When the hydrocyclone After the solid-to-liquid ratio of the internal crystal slurry reaches 35%, the crystal slurry is introduced into an alkali filter for separation, and the solid obtained after separation is calcined to obtain soda ash.
Embodiment 2
[0013] Example 2. A method for separating crystal slurry in the production process of soda ash. After sodium bicarbonate crystallization is synthesized in a carbonization tower, the crystal slurry is taken out from the carbonization tower and introduced into a hydrocyclone for hydrocyclone separation. When the hydrocyclone After the solid-liquid ratio of the inner crystal slurry reaches 40%, the crystal slurry is introduced into the alkali filter for separation, and the overflow mother liquor exported from the overflow port of the liquid cyclone separator enters the soda production system for recycling, and the solid obtained after separation is recycled. Calcined to obtain soda ash.
Embodiment 3
[0014] Example 3. A method for separating crystal slurry in the production process of soda ash. After sodium bicarbonate crystallization is synthesized in a carbonization tower, the crystal slurry is taken out from the carbonization tower and introduced into a hydrocyclone for hydrocyclone separation. When the hydrocyclone After the solid-to-liquid ratio of the internal crystalline slurry reaches 38%, the crystalline slurry is introduced into an alkali filter for separation, and the solid obtained after separation is calcined to obtain soda ash.
