Application in heating domestic water
Air compressor waste heat recovery It mainly recovers the heat generated by the compressed air of the air compressor. The oil circuit of the air compressor is cooled by cold water to produce hot water for domestic use. According to engineering experience, the heat that can be recovered by the lubricating oil circuit system accounts for about 60% of the waste heat. This part of the heat can be used for daily bathing, heating and constant temperature, and low-temperature process heating. Our company operates heat exchanger products: plate heat exchanger, H
Introduction to brazed plate heat exchanger
Brazing refers to a welding method in which the filler metal lower than the melting point of the weldment and the weldment are simultaneously heated to the melting temperature of the solder, and then the liquid filler metal is used to fill the gaps between the solid workpieces to connect the metals. Divided into hard soldering and soft soldering. Brazing is a brazing process where the melting point of the filler metal is higher than 450°C. Brazing materials include copper-based, silver-based, aluminum-based alloys. Commonly used fluxes include sand, boric acid,

Brazed plate heat exchanger Notes and FAQs
Brazed plate heat exchangers should not be installed where there is strong vibration, cyclic pressure or temperature changes. If there is a potential risk of vibration in the installation, a shock absorbing device should be added to ensure that vibration is not transmitted to the brazed plate heat exchanger. Pay attention to the maximum load that the pipe connections can withstand. When the evaporation temperature under operating conditions is close to the liquid temperature on the refrigeration side, corresponding antifreeze measures need to be taken.
R&D design and testing capabilities
Heat exchange and its system are important energy-saving equipment. Each plate replacement model of THT Juyuan is strictly tested by the National Heat Exchange Product Quality Supervision and Inspection Center (referred to as the National Inspection Center), and a performance test report is issued. The selection software is certified and registered by AHRI and undergoes compliance verification every year, ensuring the accuracy of plate heat exchanger selection calculation
Application of brazed plate heat exchanger
The selection design uses special software to perform data iteration calculations to complete the thermal and hydraulic calculations of the heat exchanger, including inter-plate flow velocity, corner hole flow velocity, resistance drop, thermal mixing design, heat transfer coefficient, logarithmic average temperature difference and heat transfer area, etc., and can calculate the resistance drop at the corner holes and the resistance drop between the flow channels respectively as required, and can make corresponding economic analysis on the selected model of the heat exchanger.
System product technology-Desalination system
The seawater desalination system is a process that uses MVR technology to evaporate circulating seawater to produce secondary steam condensation to condense fresh water. The concentrated seawater is discharged after salt removal, and the condensed fresh water is treated with chemicals to form domestic water. main application •For special occasions such as islands far away from the mainland that lack energy, offshore operating platforms, maritime emergency rescue, scientific expeditions and short-term small amounts of seawater desalination needs.
System product technology-multi-effect evaporation system
In multi-effect evaporation, heating steam is added to the first effect. The secondary steam generated from the first effect is used as the heating steam for the second effect. The heating chamber of the second effect is equivalent to the condenser of the first effect. The secondary steam generated from the second effect is used as the heating steam for the second effect. The secondary steam is used as the third effect heating steam. Multiple evaporators are connected in series to form multi-effect evaporation. Since the operating pressure of the evaporation chamber is reduced effect by effect

Application of low-temperature waste heat power generation
Low-temperature waste heat power generation uses the principle of the Organic Rankine Cycle (ORC), which uses low-boiling point organic matter as a working fluid to absorb heat from the waste heat through a heat exchanger to generate steam with a certain pressure and temperature, which enters the turbine machinery to expand and perform work. It drives the generator to generate electricity, and then releases heat to the cold water through the condenser, and this cycle continues.
