Abstract

The invention belongs to the field of industrial technology, and in particular relates to distillation equipment for coal tar hydrogenation process. The technical problem to be solved by the present invention is to provide a distillation equipment for coal tar hydrogenation process with short distillation time for dehydrating coal tar and thorough separation of light oil and heavy oil. A distillation equipment for coal tar hydrogenation process, including a distillation tank, a heater, a first gas outlet pipe, a second gas outlet pipe, a distillation power mechanism, a material discharge mechanism, a driving mechanism, a heating plate, a collecting box, a funnel, and a liquid extraction mechanism, an inverted V-shaped rod, a vertical rod, a connecting rod, a second slide rail, a second slider and a second elastic member; a second outlet pipe is installed on the left side of the top of the retort, and a heater is arranged on the top of the retort. The invention achieves the effects of short distillation time of dehydrated coal tar, thorough separation of light oil and heavy oil, large contact area between dehydrated coal tar and heating plate and easy flow of dehydrated coal tar from the heating plate.

Description

technical field [0001] The invention belongs to the field of industrial technology, and in particular relates to distillation equipment for coal tar hydrogenation process. Background technique [0002] Coal tar must be pretreated before entering the hydrogenation unit to remove water, impurities and asphaltenes and other components, so that the hydrogenation process can proceed normally. Therefore, the research on the pretreatment process of coal tar is of great significance in improving energy efficiency, reducing energy consumption and increasing corporate profits. [0003] In the prior art, most of the dehydrated coal tar is added into the heater for heating, so that the light oil evaporates into light oil vapor by itself, so the distillation time of light oil and heavy oil is longer, and the separation of light oil and heavy oil is not complete. In the prior art, when the dehydrated coal tar is added to the heater for heating, it is stirred. This method will make the sm...
