一种粗苯生产设备

Crude benzene production equipment

Abstract

The utility model discloses crude benzene production equipment, which relates to the technical field of coking production equipment, in particular to the benzene production equipment. The benzene production equipment comprises a benzene washing tower, a fluorine machine station, an oil-water separator, an efflux ditch, an oil-oil heat exchanger and a benzene removing tower, and is characterized by further comprising a three-dimensional heat exchanger, wherein the three-dimensional heat exchanger comprises an oil-gas heat exchanger and a crude benzene condenser cooler; the oil-gas heat exchanger is arranged on an upper layer of the three-dimensional heat exchanger; and the crude benzene condenser cooler is arranged on a lower layer of the three-dimensional heat exchanger. In conclusion, according to the utility model, the original crude benzene condenser cooler in the existing crude benzene production equipment is changed into the three-dimensional heat exchanger, so the benzene acquisition steam temperature is reduced and rich oil is simultaneously pre-heated before entering the oil-oil heat exchanger. Therefore, the efficiency of the oil-gas heat exchanger and the crude benzene condenser cooler in the three-dimensional heat exchanger is improved, the energy consumption is reduced, and the output and the quality of crude benzene are increased.
本实用新型公开了一种粗苯生产设备,涉及焦化生产设备技术领域,具体涉及粗苯生产设备。粗苯生产设备包括洗苯塔、氟机站、油水分离器、外排沟、油油换热器和脱苯塔;其特征在于:还包括三维换热器,三维换热器包括油气换热器和粗苯冷凝冷却器,油气换热器设置于三维换热器的上层,粗苯冷凝冷却器设置于三维换热器的下层。综上所述,本实用新型将现有粗苯生产设备中原粗苯冷凝冷却器改为三维换热器,在降得苯蒸汽温度的同时让富油在进入油油换热器前也得到了预热,由此提高了三维换热器中的油气换热器和粗苯冷凝冷却器效率,降低了能耗,提高了粗苯的产量和质量。
