The utility model discloses a coal tar separating device, which relates to the technical field of coal tar production and comprises a bottom plate and a U-shaped plate, the U-shaped plate is fixedly arranged on one side of the upper surface of the bottom plate, a rotating rod is rotatably arranged in the middle of the upper surface of the bottom plate, and a rotating plate is fixedly arranged at the top end of the rotating rod. A first motor is fixedly arranged on the lower surface of the bottom plate, the output end of the first motor is fixedly connected with the lower end of a rotating rod, transmission rods are rotationally arranged in the two sides of the rotating plate, centrifugal barrels are fixedly installed at the lower ends of the transmission rods, and baffles abut against the two sides of a U-shaped plate; one side of the lower end of the U-shaped plate is rotationally sleeved with a transverse rod, and the two ends of the transverse rod are fixedly connected with the corresponding baffles respectively. According to the coal tar separator, the double centrifugal barrels are arranged, so that highly continuous coal tar separation work can be carried out, the time wasted by cleaning the centrifugal barrels can be reduced, and the production efficiency can be further improved.

The invention belongs to the technical field of functional application materials and coal chemical industry, and discloses an intelligent response type coal tar viscosity reducer and a preparation method and application thereof.The viscosity reducer serves as a novel intelligent material, the temperature and pH dual response mechanism is integrated into one molecule for the first time, the leap from a static material to a dynamic intelligent material is achieved, and the application prospect is wide. The viscosity reduction behavior of the viscosity reducer can be adaptively adjusted according to environmental conditions, the intelligent effects of strong viscosity reduction at low temperature / unfavorable pH and moderate viscosity reduction at high temperature / neutral pH are achieved, the dynamic requirements of a coal tar whole-flow process are perfectly matched, and the viscosity reducer has essential leap with a traditional viscosity reducer with fixed functions.
