本文针对内燃机冷热电联供系统缸套水低品位余热无法高效回收利用的难题,利用缸套水低品位余热驱动LiCl溶液吸收式除湿机组,搭建实验平台,改变内燃机输出功率,研究LiCl溶液吸收式除湿机组性能变化情况。内燃机输出功率从18 kW增加到50 kW,内燃机缸套水热负荷增加,再生器的再生能力增强,再生液脱水量△mg从0.84 g/s升高到1.02 g/k,再生液浓度从33.3%升高到34.0%;除湿器的性能增强,送风温度从21.1℃升高到22.5℃,相对湿度从49.49%降低到41.97%,溶液的除湿量从0.69 g/s增加到0.76 g/s。
In this paper, aiming at the problem that low-grade waste heat of cylinder water can not be efficiently recycled, the LiCl solution absorption dehumidification unit is driven by low-grade residual heat of cylinder liner water to build an experimental platform to change the output power of internal combustion engine. Dehumidifier performance changes. The output power of internal combustion engine increased from 18 kW to 50 kW, the heat and water load of cylinder liner increased, the regeneration capacity of regenerator increased, the amount of dehydration △ mg increased from 0.84 g / s to 1.02 g / k and the concentration of regenerant increased from 33.3 % Increased to 34.0%. The performance of dehumidifier was enhanced. The temperature of air supply increased from 21.1 ℃ to 22.5 ℃ and the relative humidity decreased from 49.49% to 41.97%. The dehumidification capacity increased from 0.69 g / s to 0.76 g / s .
