Under the guidance of the "dual carbon" goals, the recovery and utilization of waste heat in the industrial sector has become a key path for energy conservation and carbon reduction. The LYHP type twin-screw steam compressor heat pump system, with its highly efficient energy recovery and conversion technology, breaks through the bottleneck of traditional waste heat utilization, providing low-carbon solutions for industries such as chemical engineering, pharmaceuticals, and food processing, and has become a core equipment for promoting the green transformation of industry. This system takes the twin-screw compressor as its core and innovatively adopts the steam recompression technology (MVR). Through mechanical work, it compresses and heats low-grade industrial waste heat steam (50-90℃) to medium and high-temperature steam (100-140℃), achieving the recycling of heat. The core component, the twin-screw rotor, adopts a 4:6 symmetrical tooth profile design and is precisely processed by a CNC grinding machine. The meshing clearance is controlled within 0.015mm, ensuring high sealing performance during the steam compression process. The volumetric efficiency is as high as over 95%, far exceeding that of traditional piston compressors. Meanwhile, the rotor is made of high-temperature resistant alloy material, capable of withstanding a temperature of 160℃ and a pressure of 1.8MPa, making it suitable for complex industrial working conditions. Effective energy conservation and intelligent control are its core competitiveness. The COP value (energy efficiency ratio) of the system can reach 3.8 to 5.2, saving more than 70% of energy compared with traditional electric heating equipment. A system with a processing capacity of 10 tons per hour can save over 3,000 tons of standard coal and reduce carbon emissions by 8,000 tons annually. Equipped with an industrial-grade PLC intelligent control system, it integrates triple sensing monitoring of steam temperature, pressure and flow, enabling stepless load regulation from 0 to 100%, with a response time as fast as 0.05 seconds, ensuring precise matching of heat supply and demand. In addition, the system is equipped with a remote operation and maintenance module, which supports functions such as fault early warning and parameter optimization, reducing the cost of manual management. In industry applications, this system demonstrates wide adaptability. Distillation columns in the chemical industry
