Description

Technical Field

[0001] The utility model relates to the technical field of coal tar recovery, in particular to an environmentally friendly coal tar recovery and treatment device. Background Art

[0002] The coal tar dehydration process typically includes five steps: separation of solid impurities, heating pretreatment, distillation separation, cooling and condensation, and product storage. The distillation separation process involves fractionating the preheated coal tar using a distillation tower. During the distillation process, water, due to its low boiling point, evaporates as heat is supplied. Furthermore, the coal tar distillation separation process produces both target products and by-products. The heat generated during coal tar production cannot be effectively recycled or processed, resulting in significant waste.

[0003] The utility model patent with authorization announcement number CN220322086U discloses a heat recovery device for coal tar dehydration treatment. The utility model includes a condensing air supply pipe; three guide pipes are provided on the outer side of the condensing air supply pipe, and the three guide pipes are provided with guide pipe valves. The guide pipes are connected to a heat exchange box, and an exhaust gas collecting pipe is provided on the left side of the lower end of the rear side of the heat exchange box. The exhaust gas collecting pipe is provided with a collecting pipe valve, and the ends of the exhaust gas collecting pipes are connected together through an exhaust gas discharge pipe, and the end of the exhaust gas discharge pipe is connected with a Y-shaped three-way pipe. The heat recovery device for coal tar dehydration treatment can recycle the heat in the products and by-products produced in the process of coal tar dehydration distillation separation. The recovered heat energy can be used for preheating the coal tar raw material and preheating the air sent into the burner, avoiding waste of heat energy; during the heating and distillation process of the coal tar raw material, water vapor and hydrocarbon gas first enter the water vapor condensation box through the condensing air supply pipe and the guide pipe to exchange heat with the raw oil.

[0004] While the aforementioned utility model can recover heat from hot gas, the recovered product is coal tar. Oil stains can adhere to the surface of the product during processing, and these stains are harmful to the human body. Therefore, it is necessary to conveniently clean the oil stains generated by coal tar production. In view of this, we propose an environmentally friendly coal tar recovery and treatment device.
