Efficient flue gas type lithium bromide absorption type cold and hot water unit for eliminating white smoke

Abstract

The invention relates to an efficient flue gas type lithium bromide absorption type cold and hot water unit for eliminating white smoke. The efficient flue gas type lithium bromide absorption type cold and hot water unit is characterized in that a flue gas heat exchanger (18) is arranged on a smoke exhaust pipe of a high-pressure flue gas generator (1) of the unit firstly, and then a flue gas solution heat exchanger (27), a flue gas solution heat exchanger dilute solution inlet pipeline (28) and a flue gas solution heat exchanger dilute solution outlet pipeline (29) are additionally arranged.When the refrigerating working condition runs, a dilute solution enters the flue gas solution heat exchanger to recycle flue gas waste heat, and the flue gas is exhausted after the flue gas releases heat and the temperature is lowered. When the heating working condition runs, low-temperature refrigerant water in a flash evaporator enters the flue gas heat exchanger to recycle flue gas waste heat,the dilute solution enters the flue gas solution heat exchanger to heat normal-temperature flue gas, and the flue gas is exhausted after the flue gas of which the relative humidity is reduced absorbsheat and the temperature is increased. According to the efficient flue gas type lithium bromide absorption type cold and hot water unit for eliminating the white smoke, a chimney can adopt a conventional material and has no special requirements, flue gas heat can be recycled while the white smoke is effectively eliminated, and the comprehensive utilization rate of energy sources of the whole system is increased.

Problems solved by technology

However, in winter, the outdoor temperature is low, and the normal temperature exhaust gas temperature is lower than the dew point temperature of the flue gas. There will still be condensate in the chimney, and the conventional carbon steel chimney will be corroded by the condensate, which puts forward special requirements for the material of the chimney. It needs to be made of corrosion-resistant materials, which increases the investment cost
