AI Technical Summary

Problems solved by technology

In the existing technology, the water injection capacity of the electric heating boiler in the heat source link of the heating part of the system cannot be adjusted. When matching hydrothermal high-gloss moulds, the phenomenon of "big horse-drawn carts" with large boilers for small molds often occurs, resulting in wasted power consumption. The waste heat recovery link uses a multi-stage condenser to heat the mold to a temperature of 175°C, 0.9MPa high-pressure high-temperature steam-water mixture, condense step by step, reduce the temperature and reduce the pressure to 100°C, and then recycle it after one atmosphere, which can still be wasted The high-temperature heat energy used has the disadvantage of low utilization rate of heat energy; at the same time, in the cold source link of the water-cooled part of the system, a refrigerator is used to make the cooling water into 5°C low-temperature frozen water as the cooling carrier. There are insufficient economical and energy-saving deficiencies; therefore, existing technologies have the problems and deficiencies of large energy consumption and low thermal energy utilization
