Primary hydrogenation pre-converter with additional heating pipeline

The invention discloses a primary hydrogenation pre-converter with a heating pipeline, and belongs to the technical field of coke oven gas desulfurization devices. The technical problem to be solved is to provide a primary hydrogenation pre-converter which can meet a temperature requirement. The technical scheme adopted by the invention is as follows: according to the primary hydrogenation pre-converter with the heating pipeline, a primary heating pipeline is arranged at an outlet of a secondary hydrogenation converter; the heating pipeline is communicated with an inlet pipeline of the primaryhydrogenation pre-converter; and a control valve is arranged on the heating pipeline. The primary hydrogenation pre-converter provided by the invention is applied to desulfurization of coke oven gas. 种增设加温管线的级加氢预转化器，属于焦炉气脱硫装置技术领域，所要解决的技术问题是提供种能够满足温度要求的级加氢预转化器，所采用的技术方案：种增设加温管线的级加氢预转化器，在二级加氢转化器的出口设置趟加温管线，并且所述加温管线与级加氢预转化器的进口管线连通，在所述加温管线设有控制阀门，本发明应用于焦炉气脱硫。
