Determination of exhaust heat ventilation rate in rubber vulcanization workshop based on effective thermal coefficient of work area

结合实际工程,分析了理想补风条件下单台硫化机的有效散热量系数与排热通风量和设备散热量的关系,并探讨了排风口高度和围挡高度对有效散热量系数的影响。对实际采用两端集中补风方式的硫化机生产线,引入修正系数对单台硫化机理想补风下的有效散热量系数进行了计算,得到了系统所需的最小总排热通风量。研究结果表明,当硫化机的台数为1,7,14,21台时,对单台硫化机通风量的修正系数分别为1.00,1.36,1.45,1.64。

With an actual project, analyses the relationship between the effective thermal coefficient of a single vulcanizing machine and the exhaust heat ventilation rate and the heat dissipation of equipment under ideal air supply conditions. Studies the effects of the exhaust outlet height and the enclosure height on the effective thermal coefficient. On the basis of determining the ventilation rate of single vulcanizing machine, introduces the correction coefficient to obtain the minimum total exhaust heat ventilation rate required by an actual production line of vulcanizing machine with centralized air supply from both ends. The results show that when the number of vulcanizing machines is 1, 7, 14 and 21, the correction coefficient of the ventilation rate for a single vulcanizing machine is 1.00, 1.36, 1.45 and 1.64, respectively.
