1、 Working principle

The horizontal tube evaporator adopts a unique double-sided phase change heat transfer design with external evaporation and internal condensation. The liquid is pumped to the distributor through a circulating pump and evenly sprayed onto the outer surface of the horizontally placed heat exchange tube bundle. The material liquid is partially evaporated by the latent heat released by the condensation of steam inside the tube. The unevaporated material liquid is discharged one by one under the action of gravity and finally collected at the bottom of the evaporation chamber. It is then circulated and sprayed by a circulation pump to achieve concentration requirements through multiple cycles. The secondary steam generated by the evaporation of the material liquid is discharged from the top and can enter the next effect heat exchange tube to condense and release heat, achieving energy cascade utilization.

2、 Main features

1. Industry leading energy-saving performance

Integrating multiple energy-saving measures such as compressors, injectors, pressure reducing evaporation, and multi-stage steam reflux; Stable operation under minimal heat exchange temperature difference, maximizing the reduction of evaporation energy consumption; Secondary steam can be reused with multiple effects, leading the industry in energy utilization efficiency.

2. Small stature, great ability

Adopting a horizontal tube heat exchange structure, a larger heat exchange area can be obtained in the same space; Compact structure, small footprint, excellent heat transfer capacity; Reduce the demand for heat exchange temperature difference, thereby reducing compressor power and achieving a perfect balance between energy conservation and miniaturization.

3. Excellent heat transfer performance

The heat transfer efficiency is about twice that of traditional evaporation devices; Bilateral phase change heat transfer with high heat transfer coefficient, involving evaporation of solution outside the tube and condensation of steam inside the tube; The boiling point increase caused by static pressure without liquid level results in minimal loss of heat transfer temperature difference.

4. Fully automatic intelligent control

Equipped with a PLC control system to achieve one click start stop and automatic operation; Real time monitoring of material and liquid pumps, valves, flow meters, as well as parameters such as temperature, pressure, and specific gravity; Automatically execute operating procedures such as evaporation, cleaning, and shutdown; Intelligent alarm protection system to prevent equipment damage and maintain dynamic balance.
