Above-mentioned dry method coke removing appts., its described gas retort are selected from Chinese Fushun type retort, Brazilian Pei Teluosekesi gas retort or Estonia's Abel Kiviat gas retort.
Above-mentioned dry method coke removing appts., its described on-mechanical formula loop seal is selected from the L shaped valve or the U-shaped valve of circulating fluidized bed.
Above-mentioned dry method coke removing appts., its described sealed crusher are selected from jaw crusher, ring is beaten formula crusher or impact breaker, and its top is provided with opening for feed, and the bottom is provided with discharge port.
Above-mentioned dry method coke removing appts., its described gas retort is one or more sets parallel connections, its gas retort ash discharging hole is a plurality of pants shapes.
Above-mentioned dry method coke removing appts., its described adjustable type ash ejector is the low speed rotation formula, its external diameter is than the little 160～200mm of ash discharging hole internal diameter.
The utility model compared with prior art, have significant technical progress and positive effect: with a kind of oil shale oil-refining stove of the utility model dry method coke removing appts., resulting oil shale semi-coke contains free moisture hardly, thermal value can reach 600～1500kcal/kg, is much higher than semicoke as received basis calorific value in the wet method decoking process.(calorific value 1000～3000kcal/kg) mixes the back by a certain percentage and forms propellant combination, and calorific value guarantees more than 800kcal/kg, can directly send into burning utilization in the circulating fluidized bed with dry process semicoke that obtains and the chip shale that can not refine oil.
The great advantage of this device is to utilize the principle of circulating fluidized bed revert system to the air seal effect, decoking with gas retort, the semicoke fragmentation, and utilize in the standpipe solid material envelope that the air seal effect organically is combined into one, realized the needed device of dry method decoking, simultaneously the shattering process of semicoke has been moved on to the destructive distillation furnace side by the crushing system of boiler and realize.The semicoke that this device obtained and the propellant combination of resinous shale can stable burnings in circular fluid bed, fuel crushing and feeding system working stability, and no latch up phenomenon, the heated surface at the end of boiler corrosion is lighter.
