Combination type gas full-cycle retort

A combination type gas full-cycle retort, which is formed by a plurality of carbonization sub-elements, can be used for oil shale dry distillation refining with the technology of gas full-cycle retort. The combination type gas full-cycle retort is characterized in that an air placement chamber, a herringbone beam, a herringbone baffle, lattice walls, a cooling water jacket, a coke exhaust channel, a coke pusher, a scraper conveyer and a water seal tank are disposed inside each carbonization sub-element of the gas resort in sequence from top to bottom. The lattice walls of the carbonization sub-elements are disposed at the bottom vertically. A channel is formed between every two lattice walls. Nozzles which are used for cold cycle gas and thermal cycle gas are disposed on the lattice walls. The gas full-cycle technology is used for the oil shale dry distillation refining. Daily handling capacity of the retort which can reach above 6000 tons is in proportion to the number of the carbonization sub-elements. The
