INDUSTRIAL CRACKER FOR PLASTICS, RUBBER, OIL SHALE AND BIOLOGICAL STRAWS

摘要

The present invention relates to an industrial cracker for plastics, rubber, oil shale and biological straws. An oil gas cylinder is fixed at the top of a heat conduction box in a sealing manner. A material inlet and an oil gas outlet are formed in the oil gas cylinder. A left cracking cylinder and a right cracking cylinder which are fixed to the oil gas cylinder in a sealing manner are arranged in the heat conduction box at the bottom of the oil gas cylinder. A left screw propeller and a right screw propeller are respectively arranged in the left cracking cylinder and the right cracking cylinder. The oil gas cylinder is communicated with inner cavities of the left cracking cylinder and the right cracking cylinder in a sealing manner. A slag feeding pipe and a lower-positioned slag discharging pipe are respectively arranged at the bottoms of the left cracking cylinder and the right cracking cylinder. The lower-positioned slag discharging pipe is communicated with a slag inlet of a serial circulating heat-carrier heater, and the slag feeding pipe is communicated with a slag outlet of the serial circulating heat-carrier heater. Higher-positioned slag discharging pipes are arranged on the left cracking cylinder and the right cracking cylinder and discharge redundant carbon slag. A combustion chamber is arranged at the bottom in the heat conduction box, and smoke outlets are formed in the two sides of the upper part of the combustion chamber. The carbon slag generated by the cracking of materials is used as a heat carrier. The industrial cracker can realize continuous industrial operation, is high in efficiency and low in cost.
