新型宽厚焊接型板式换热器的开发和应用

Development and Use of Novel Wide and Thick Welded Type Plate Heat Exchanger

采用新型宽厚焊接型板式换热器替代传统胶垫型板式换热器,提高了防泄漏和防堵塞性能与换热效率,降低了工序能耗,取得了满意的使用效果。新型宽厚焊接型板式换热器投运后,年多回收粗苯720t,年增加经济效益380万元;年节约煤气180000m3(标态),年节约费用216万元。

A novel wide and thick welded type plate heat exchanger is adopted to replace the conventional rubber padded plate heat exchanger, thereby improving the leak-proof and blocking-proof properties and heat exchange operation results are obtained. recovered annually, economic state） of gas are saved a year efficiency and reducing the process energy consumption, satisfactory After the commissioning of the exchanger 720 t of crude benzene are benefit is increased by 3.80 million yuan a year, 180 00 m^3 （ standard and 2.16 million yuan are saved a year.
