【摘要】：研制了一种新型的矿用混合式空冷器,装置由喷淋装置和表面式空冷器组合而成。喷淋装置的喷淋水可采用天然冷源,一方面可承担一部分的矿井降温冷负荷,另一方面冲刷了表面式空冷器表面的大量污垢,提高了表面式空冷器的传热系数。表面式空冷器的冷冻水来自人工冷源,承担另一部分的矿井降温冷负荷。对提出的新型矿用混合式空冷器给出热工计算的设计方法,并进行了实例计算,热工计算结果表明:矿用混合式空冷器能较好地应用于矿井降温系统,与传统空冷器相比,可节约一部分的矿井降温能耗。提出的新型矿用混合式空冷器,可有效满足粉尘浓度大、降温负荷大的矿井降温系统的需要,并且能耗较低。
[Abstract]:A new type of mixed mine air cooler is developed, which is composed of spray device and surface air cooler. The spray water of the sprinkler can use natural cold source, on the one hand, it can bear part of the cooling load of mine, on the other hand, it scour a large amount of dirt on the surface of the surface air cooler, and improve the heat transfer coefficient of the surface type air cooler. The surface air cooler chilled water comes from artificial cold source and undertakes another part of mine cooling load. The design method of thermal calculation for a new type of mixed air cooler used in mines is given, and a practical example is given. The results of thermal calculation show that the hybrid air cooler used in mine can be applied to the mine cooling system better than the traditional air cooler. Can save part of the mine cooling energy consumption. The new mine mixed air cooler can meet the needs of mine cooling system with high dust concentration and heavy cooling load, and the energy consumption is low.
