AI Technical Summary
Technical Problem
Existing concentrated liquid evaporation and crystallization technologies have shortcomings in terms of equipment self-cleaning function, continuous operation stability, and process integration, resulting in frequent system shutdowns for cleaning and a decrease in thermal efficiency.
Method used
The heating chamber is arranged at an angle and works in tandem with a coaxial spiral lifting assembly. Combined with a chain-driven scraper self-cleaning mechanism, the heating wall and conveying components are automatically cleaned to prevent scaling.
Benefits of technology
It significantly improves the continuous operation stability and thermal efficiency of the equipment, reduces the frequency of downtime for cleaning, simplifies the process flow, and lowers operating costs.

Abstract
The application discloses a concentrated liquid crystallization equipment and landfill leachate treatment process. A conveying structure is formed by an obliquely arranged heating cavity and a coaxially arranged spiral lifting assembly. The outer edge of the spiral blade is in sliding abutment with the wall surface of the heating cavity, and the wall surface crystalline layer is scraped synchronously during the lifting of the material. Meanwhile, the blade cleaning assembly above the heating cavity drives the scraper by using a one-way chain that can only bend inward, and continuously cleans the upper surface of the spiral blade. The treatment process converts the total amount of leachate into purified water, recycled condensed water and crystallized salt through the processes of pretreatment, core purification suitable for biodegradability, membrane concentration and end evaporation crystallization. The application solves the technical problems of the traditional evaporation crystallization equipment, such as the scaling of the heating wall surface and the conveying components, the frequent shutdown for cleaning and the reduction of heat efficiency, by deeply coupling the equipment self-cleaning structure and the process optimization, and improves the stability and treatment efficiency of the continuous operation of the system.
