Research on application of heat recovery to process double circulation water-cooled system in a wine factory area

During the production process of Jiang-flavour Chinese spirits,cooling is needed to make alcohol vapor condense into wine and cool it down to the required wine outlet temperature.The normal mediums to cool wine include air and water,and during the cooling process,the alcohol vapor will release a large amount of heat into the cooling medium.When using the air cooling mode,the heat is released into the air,and it is difficult to recover and utilize.Under normal circumstances,when using the water cooling mode,the outlet temperature of the cooling water is about 60 to 70 ℃,which can be used to heat domestic hot water and boiler water,but the rest of heat can not be used for any other heat recovery methods.In order to improve the utilization rate of waste heat from cooling water in the production of wine,a process double circulation water-cooled system is proposed.By using the method,its high-temperature cooling water outlet temperature can reach about 90 ℃,and the heat in the high-temperature cooling water accounts can reach to 90% and can be used to drive a heated heat pump to produce steam,and can also be used to heat boiler water and domestic hot water.The double circulation water-cooled system will improve the recovery and utilization rate of waste heat in Jiang-flavour Chinese spirit production,and achieve the effect of energy-saving and low-carbon.
