Titanium Welding Coil Tube

 Mechanical steam recompression technology (MVR) utilizes the secondary steam and its energy generated by the evaporation system itself to increase the mechanical work of low-grade steam through the compressor into a high-grade steam heat source. This cycle provides thermal energy to the evaporation system, thereby reducing the demand for external energy as an energy-saving technology.

Its structural components mainly include: compressor, evaporator, heat exchanger, and gas-liquid separator. In the heat exchanger, the cold and hot fluids do not come into direct contact, but exchange heat through the interlayer. The commonly used types of inter wall heat exchangers in production include: tubular heat exchangers, corrugated heat exchangers, and spiral heat exchangers. When using MVR technology to treat high concentration saline wastewater, due to its high concentration and high boiling point rise, the corresponding steam compressor needs to increase the temperature to overcome the impact of boiling point rise. At this time, the heat exchanger needs to use titanium tubes to resist high temperature, high pressure, and salt corrosion.
