This paper summarized the new technologies and new equipments adopted in solvent deasphalting units in China during recent years, including: mixed C_4 solvent deas- phalting process, pressurized solvent recirculation system, super-critical solvent recovery, two-stage extraction technology, light deasphalted oil critical plus 2-effect evaporation sol- vent recovery, residuum super-critical extraction, comb-type grid packing for extraction, new magnetic pressure pump, interface indicator for extractor bottom, saddle-type packing for heat-exchaning washing, fin air preheater, and using screw pump in the place of steam pump. Some imported technologies are compared with domestic ones, such as: mixer extrac- tion against tower extraction, differences between predilution schemes, super-critical reco- very and multi-effect evaporation recovery vesus subcritical recovery, etc. suggestion for in- creasing the capacity of the unit, increasing the yield of deasphalted oil and reducing the en- ergy consumption are put forward.

综述了我国溶剂脱沥青装置近年来开发应用的新工艺、新技术和新设备:混合C_4溶剂脱沥青工艺、溶剂增压循环流程、超临界溶剂回收、沉降法两段抽提工艺、轻脱沥青油溶剂临界回收加二效蒸发回收工艺、渣油热加工-脱沥青工艺、渣油超临界抽提工艺,蜂窝式格栅抽提填料、新型磁力传动增压泵、抽提塔底界面计、换热洗涤塔采用矩鞍环填料、沥青加热炉同时加热沥青和轻脱沥青液、扰流子翅片管空气预热器、螺杆泵代替蒸汽泵等;就混合器抽提与抽提塔抽提、预稀释方案的差异、超临界回收及多效蒸发回收与亚临界回收等,对引进技术和国内技术进行了对比分析,并就当前存在的主要问题,如装置负荷低、脱沥青油收率低和能耗、剂耗高等提出了改进建议。

Tubular heat exchangers are used to reclaim the residual heat of automobile exhaust gas to heat asphalt. In the furnace, the cold asphalt flows in from the asphalt input of heat collector, then is heated while it flows along the helical ducts that are inserted by tubular hear exchangers and flows out from center hole at last. In this way, the asphalt is heated layer by layer and heat homogeneity is ensured. Test showed that the asphalt temperature at the center of heat collector can reach 152.5℃ after the auto...

Tubular heat exchangers are used to reclaim the residual heat of automobile exhaust gas to heat asphalt. In the furnace, the cold asphalt flows in from the asphalt input of heat collector, then is heated while it flows along the helical ducts that are inserted by tubular hear exchangers and flows out from center hole at last. In this way, the asphalt is heated layer by layer and heat homogeneity is ensured. Test showed that the asphalt temperature at the center of heat collector can reach 152.5℃ after the auto is started for 45 minutes and the venting resistance of the heaters is less than that of the original muffler, the noise level of engine is less than 84dB.

利用汽车尾气的热管式沥青加热炉,利用热管换热器回收汽车发动机排气的余热加热沥青。加热炉中的冷沥青通过螺旋集热罩的沥青入口进入螺旋通道,被叉排于其中的热管换热器首先加热后,从中心孔流出,实现了沥青的分层加热,使沥青加热均匀。试验表明,汽车行驶45min后集热罩中心处沥青温度达到152.5℃,且加热装置的排气阻力小于原消声器的排气阻力,发动机噪声≤84dB。

According to features and urgency of the highway maintenance in countryside, a furnace is designed and made by ourselves. It can heat up asphalt by means of reclaiming the heat of exhaust gas of automobile by using heat pipeTo further improve the efficiency and economy of the installation, we develop stratified heating system. Firstly, in this paper we state the work of this installation. Secondly, we analyzed and calculated in theory. The result of experience shows that the installation can meet requirement of the design. In a word, it is an efficient way for highway maintenance in the countryside in energy saving and environmental protecting.

针对农村公路的特点及农村公路养护的紧迫性,自行研制了利用汽车尾气的热管式沥青加热炉。它利用热管换热器回收汽车发动机排气的余热去加热沥青,同时为了进一步提高加热装置的效率、经济性,设计并制造了分层加热系统。本文首先讲述了该装置的工作原理,然后通过理论分析、计算,结果表明该设备能够满足设计要求,各项参数符合国家标准。是一种良好的节能、环保型农村公路养护设备。
