Description

Energy ball circulator and plate type heat transfer combined material pyrolysis device arranged in reaction kettle

Technical Field

Background

At present, equipment for thermally cracking materials such as waste tires, waste plastics, oil sludge, organic glass, sludge and the like is basically a cylindrical cavity converter structure, and the materials enter from one end and react and then are discharged from the other end. Because many materials have cohesiveness, coking is easy to occur on the inner wall of the reaction kettle, heat transfer is seriously influenced, and although some thinks that substances in hard blocks are added into the materials for friction, the substances cannot return to the feed end to be mixed with the materials again after running to the tail part; some have also designed to discharge the hard block in the friction and return to the front part outside the reaction kettle by other devices, and then enter the reaction kettle to be mixed with the material for operation; obviously, this structure is complex, increases the cost and wastes energy. In addition, the thermal decomposition efficiency is limited because the thermal energy in the reaction kettle is not fully utilized by simply transferring heat to the material by the reaction kettle, and therefore, a technology and equipment which can apply a certain hard substance to automatically circulate in the reaction kettle and can increase the heat transfer efficiency in the reaction kettle need to be developed.
