Detailed description of the invention
The invention discloses and a kind ofly utilize low-grade industrial exhaust heat as the dehumidification system of thermal source, this dehumidification system is included on industrial exhaust heat discharge tube and arranges LiCl solution absorbed moisture removing machine, industrial exhaust heat flows through the heat source side of LiCl solution absorbed moisture removing machine by pipeline, and LiCl solution absorbed moisture removing machine utilizes industrial exhaust heat to dehumidify to air.Wherein, low-grade industrial exhaust heat is the recirculated water for lowering the temperature in industrial wastewater, low-temperature flue gas or industry.
The present embodiment with internal combustion engine cylinder jacket hot water for waste heat thermal source establishes a set of system internal combustion engine cylinder jacket water waste heat being used for dehumidify, and be provided with multiple measurement point on this system for measuring the temperature value in each stage, to test and the utilization rate of waste heat of native system is described.
As shown in Figure 1, the jacket water outer circulation loop that the delivery port 11 that this system is included combustion engine 1 jacket water is connected to form by external pipe and its water inlet 12, heat-exchanger pump 2, LiCl solution absorbed moisture removing machine 3 and cooler 4, heat source side and the cooler 4 of heat-exchanger pump 2, LiCl solution absorbed moisture removing machine 3 are successively set on jacket water outer circulation loop.For measuring dehumidification rate, jacket water outer circulation loop being also provided with the first thermocouple thermometer 5 for measuring jacket water leaving water temperature, for measuring the three thermocouple thermometer 7 of jacket water return water temperature and the second thermocouple thermometer 6 for measuring the jacket water temperature after LiCl solution absorbed moisture removing machine 3, and measuring the flowmeter 8 of jacket water flow.
The thermal temperature that jacket water absorbs after flowing through internal combustion engine cylinder jacket on cylinder sleeve raises, the jacket water of high temperature flows into the heat source side of LiCl solution absorbed moisture removing machine 3 under the effect of heat-exchanger pump 2 by jacket water outer circulation loop, the heat of jacket water is absorbed rear temperature by LiCl solution absorbed moisture removing machine 3 to be reduced, then jacket water flows into internal combustion engine cylinder jacket water water inlet by jacket water outer circulation loop after cooler 4 is lowered the temperature again, be cylinder sleeve cooling again, so repeatedly.
The LiCl solution absorbed moisture removing machine used in this enforcement forms primarily of dehumidifier and regenerator, with LiCl solution for working medium, and dehumidifier process air quantity: 0 ~ 800m
3/ h; Wind pushing temperature after dehumidifying: (adjustable) 10 ~ 25 ± 0.5 DEG C; Air-supply relative humidity :≤50 ± 3%; Air-supply absolute humidity :≤10g/kg (dry air); LiCl solution concentration: 30% ?36%.
