More Information
Summary:The utility model discloses a modified pitch production system capable of preventing coking materials from blocking a pipeline, which comprises a pitch reaction tower, a feed port of the pitch reaction tower is connected with a tar distillation system, and a discharge port of the pitch reaction tower is connected with a heat exchanger through a pitch conveying pipeline. An asphalt circulating pump is mounted on the asphalt conveying pipeline, a discharge port of the heat exchanger is connected with an asphalt tank, and a coking material filtering and intercepting device is arranged at the discharge port of the asphalt reaction tower; the filtering and intercepting device has the beneficial effects that the structure is simple, the filtering and intercepting device can effectively filter and intercept blocky coking materials which are not thoroughly cleaned in the asphalt reaction tower, the blocky coking materials are prevented from blocking an inlet pipeline of a circulating pump, and the normal operation of
