AI Technical Summary
Existing plate heat exchangers suffer from problems such as inconvenient agent mixing and unstable agent delivery during the cleaning process, which affect the cleaning effect and efficiency. In addition, traditional disassembly and cleaning methods are time-consuming and labor-intensive, causing production interruptions.
A self-cleaning plate heat exchanger was designed, equipped with a liquid supply mechanism and a liquid mixing device to achieve efficient mixing and directional delivery of the liquid. It dissolves scale through chemical reaction and quickly discharges waste liquid through a drain pipe, avoiding disassembly and cleaning.
It achieves uniform mixing and stable delivery of the cleaning solution, improves cleaning efficiency, shortens downtime, increases production efficiency, simplifies the cleaning process, and ensures continuous operation of the equipment.
