The utility model relates to the technical field of crude benzene hydrogenation, in particular to a heavy component removal tower for crude benzene. Comprising a tower body, an upper heating assembly is arranged in the tower body, a lower heating assembly is arranged in the lower end of the tower body, an outlet is formed in the upper end of the tower body, and the lower end of the tower body is fixedly communicated with a liquid pipe. Crude benzene raw materials can be heated in the ascending and descending process of the multiple flow limiting rings and after being in contact with the baffle, so that gasified crude benzene components are discharged through the outlet, light benzene raw materials are directly discharged through the liquid pipe, and continuous heavy component removal treatment of the crude benzene raw materials is achieved. 本实用新型涉及到一种粗苯加氢技术领域，具体涉及到一种粗苯用脱重塔。包括塔体，塔体内设置有上加热组件，塔体下端内设置有下加热组件，塔体上端开设有出口，塔体下端固定连通有液管。粗苯原料在多个限流环上下行的过程中，以及与挡板接触后能够被加热进而使得气化的粗苯组分通过出口排出，轻苯原料直接通过液管排出，实现对粗苯原料的连续脱重处理。
