As the development of industry, economy, the wastage of the sources of energy is in rapid growth, consider gap of supply and demand is bigger, because this is necessary,use new-style energy-saving engineering technology. With rectification for, commonly used treatment facilities is rectification tower, the observation that passes pair of rectification courses is OK just think, if the quantity of heat cat head gas phase uses the stock end Yujiareda, the heat addition outside can be being saved and outside offer cold, achieve energy-saving result thereby.
But whether is this one just think feasible? After passing ceaseless experiment and research, discover those who heat up pump to apply eventually can help me realize energy-saving rectify, hot pump is one kind uses a few high grade mechanical energy to make microtherm the facility that heat energy temperature improves, because this heats up pump rectify can the action of hot pump of have the aid of warms up the pressurization of cat head vapour with inferior temperature, regard high temperature tower as the heat source of boiler. Use at process itself as a result of reclaiming latent heat, because this is OK,condenser of leave out cat head, cooling water and tower boiler heat vapour, reduce the specific power consumption that rectification place needs greatly. Use high temperature rectify to heat up pump technology to be able to reclaim not only the quantity of heat of steam of Duan Zheng of the high temperature in rectification process, use its heat fluid of tower bottom boiler issues more result with evaporate, return the heating capacity that can heat up pump adequately and refrigerating capacity, have good economic benefits.
