AI Technical Summary
Existing absorption heat pump technology has low energy efficiency under low temperature driving heat source conditions, low efficiency of waste heat recovery from biomass flue gas, and traditional heat exchange technology is limited to sensible heat utilization and fails to fully recover latent heat.
A multi-stage, multi-segment heat pump cycle process is constructed, combining absorption and compression heat pumps, employing efficient mass transfer and heat exchange technology, and recovering the sensible and latent heat of biomass flue gas in stages. Lithium bromide solution is used as the absorbent, and the flue gas energy is utilized in stages through multi-stage series heat pump units.
It significantly improved the efficiency of flue gas waste heat recovery, reducing the flue gas temperature from 145℃ to 35℃, thereby improving the thermal energy utilization rate and the overall energy utilization rate.
