| 中文摘要: |
| 针对夏季印刷车间空气处理过程中，由于控制室内温湿度波动而采取再热措施造成冷热抵消的能源浪费现象，
根据空气处理过程焓湿图分析了西安某印刷车间夏季空气处理产生再热的原因，并在对印刷产生有机废气采用局部排
风进行有效收集处理的基础上，针对性地提出了利用热回收以补偿再热负荷的思路。比较了几种常见热回收装置的特
点，根据对印刷有机废气催化处理后排放尾气的温度，选择了热管式显热回收方式，进而分析了其传热量及显热回收效
率的计算过程，突出了其节能优势，最终达到充分利用废热节能的目的。 |
| 英文摘要: |
| By wasting of energy during the process of air treatment in printing workshop in summer in Xi'an. which is
caused by reheating to control the fluctuation of temperature and humidity indoor. the reasons of reheating were proposed
based on h-d graph. Then the idea of using technologies for reheating was given based on the treatment means of organic
exhaust gas. Characters of several heat recovery equipments were compared, and the thermotube type equipment for
sensible heat recovery was chosen on the basis of tail gas's temperature of catalytic oxidation about organic exhaust gas.
The computational process was discussed with the highlighted superiority of energy conservation. The final purpose was to
take advantages of waste heat to save energy. |
