Description

Technical Field

[0002] When treating high-salt wastewater, evaporation and crystallization are usually used to treat the wastewater. The existing evaporation and crystallization device usually includes a tank body, a liquid inlet pipe, a steam outlet, a crystal scraping component and a crystal discharge tube. Wastewater is injected into the tank body through the liquid inlet pipe, the tank body is started to be heated, and the wastewater evaporates and desalinates to form crystals. The crystal scraping component scrapes the crystals to the crystal discharge tube and then discharges them from the crystal discharge tube. However, this device requires the tank body to be shut down after each evaporation and crystallization is completed, and then the crystals are discharged.
