Zinc sulfate MVR evaporative crystallizer

Zinc sulfate is an important inorganic chemical product with many applications in industry, agriculture, and other fields. The entire production process, including evaporation, filtration, and drying, is operated automatically without excessive human intervention.

Zinc sulfate is an important inorganic chemical product with many applications in industry, agriculture, and other fields. Research data shows that zinc sulfate crystallizes into ZnSO4 · 7H2O at temperatures ranging from 0 to 39 ℃; At 39-70 ℃, the crystal forms ZnSO4 · 6H2O; Crystallization above 70 ℃ results in ZnSO4 · H2O.

In the past, the production of zinc sulfate monohydrate crystals often used intermittent evaporation pots to evaporate and dehydrate the solution. This production method consumes a lot of steam, has a slow process, and cannot produce continuously, which has many drawbacks.

At present, some enterprises have attempted to use MVR evaporation or single effect evaporation crystallization processes for the production of zinc sulfate, but the results are not satisfactory. Scaring and blockage phenomena are very serious during the trial production process, and continuous production cannot be guaranteed.

Our company has specially designed a product evaporator for the special physical properties of zinc sulfate. After three months of continuous use by the user, it successfully passed the acceptance inspection.

This product has the following advantages:

① Capable of continuous and stable production; The phenomenon of no scar blockage affecting production;

② The entire production process, including evaporation, filtration, and drying, is operated automatically without excessive human intervention;

③ The production process is fully enclosed with no leakage or dripping, and the environment is good;

④ The production energy consumption is low, with an energy consumption of about 30 yuan per ton of water for evaporation. Calculated based on a concentration of 80g/L of feed solution, the energy cost per ton of product is about 120 yuan. The energy consumption of traditional tank evaporation is about 1.2 tons of steam per ton of water, which requires about 5 tons of steam per ton of product, and the production cost per ton exceeds 1000 yuan.
