一种PTA装置气力输送的节能方法

An energy saving method of PTA plant pneumatic conveying system

叙述了PTA装置工艺状况和风送系统情况。指出了PTA装置风送系统存在的问题,即耗气量过大,并对其理论分析,对其中的原因进行假设,并通过工业试验进行验证。证明了物料流量和风送气量之间并不是直接的线性关系。并采取措施,降低了风送气量,节约了装置的能耗。

The process status and air supply system condition of PTA plant were described. The existing problems of FTA plant air supply system were pointed out. The gas consumption was too large and its theory was analysed, the reasons were assumed and verified by the industrial test. The results showed that the material flow and the air feed- ing amount is not a direct linear relationship. Some measures were taken to reduce the air feeding amount and save the energy consumption of the plant.
