基于集中疏水技术的用汽设备疏水系统的改进
|
摘要
为解决打叶复烤企业蒸汽动力系统汽水不平衡、热能浪费大等问题,对车间工艺用汽和生活采暖用汽系统进行了改进。基于等压系统原理设计了无动力闭式集中疏水系统,代替传统疏水阀系统,应用于一次润叶机、二次润叶机、烤片机、烤梗机等用汽设备,并将收集的凝结水用于生活采暖,实现生产和采暖双重节汽。以毕节复烤厂12 000 kg/h打叶复烤生产线为对象进行测试,结果表明:改进后每吨片烟平均消耗蒸汽量比改进前下降16.79%,节约蒸汽费用14.05万元/月,每500 t(1万担)原烟节约蒸汽费用1.31万元。该技术可为打叶复烤企业节能减排、降本增效提供支持。
In order to achieve better vapor-water equilibrium and save heat energy in tobacco processing plant,the steam system for tobacco processing and domestic heating was upgraded. A centralized closed type powerless steam trap system was designed based on the principle of isobaric system to replace the traditional steam traps of the conditioning cylinders, tobacco strip redryer and tobacco stem redryer; and the collected steam condensate water was used for domestic heating to realize steam saving both in production and in domestic heating. A test was carried out on a 12 000 kg/h threshing and redrying line in Bijie Tobacco Processing Factory, the results showed that the average steam consumption per ton of tobacco strips decreased by 16.79%, or 26 200 CNY per 1 000 tons of cured tobacco. This technology provides supports for the cost and energy saving, CO emission reduction of tobacco processing enterprises.
