Problems solved by technology

The semi-coke entering the inner cylinder will not produce oil and gas, it is only used for preheating, which affects the oil and gas yield of the stove
However, the semi-coke released from the furnace is not used, which not only causes carbon waste, but also pollutes the environment.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0019] Such as figure 1 , The embodiment of the present invention comprises frame 1 and the front support roller 23 that is installed on the frame 1, rear support roller 27, rear rotary support body 25 and front rotary support body 15. Embodiments of the present invention also include a rotating inner cylinder 13 and a rotating outer cylinder 14 that are nested together and rotate synchronously. There is an annular semi-coke passage between the rotating inner cylinder 13 and the rotating outer cylinder 14. The front and rear ends of the cylinder 14 protrude, the front protruding end is seated on the front support roller 23 through the front raceway 16, and the rear protruding end is located on the rear support roller 27 through the rear raceway 7. The rear extension end is also equipped with a ring gear 6 , and the gear meshed with the ring gear 6 is conn...

Abstract

The invention provides a powdery oil shale retort for heating by using semicoke generated by retorting as fuel. An annular semicoke passage is formed between a rotating inner cylinder and a rotating outer cylinder; a chamber communicated with the annular semicoke passage is formed in a front rotation supporting body, and the chamber is connected with an ignition material inlet; a chamber communicated with the annular semicoke passage is formed in a back rotation supporting body, and a smoke outlet and a slag outlet are formed in the chamber; the front end of a spiral material pusher with a raw material injection opening is connected with the back end of the rotating inner cylinder through a back fixing cylinder and a back sealing mechanism; the front end of the rotating inner cylinder is connected with a front fixing cylinder through a front sealing mechanism; an oil gas outlet is formed in the front fixing cylinder and a semicoke conveying pipe is arranged on the front fixing cylinder; the semicoke conveying pipe is connected with a spiral semicoke feeder; the discharging end of the spiral semicoke feeder is communicated with the annular semicoke passage; a material sealing clearance is formed at the discharging end of the spiral semicoke feeder. The combustion energy of the by product semicoke of retorting is fully used and the discharge amount of the by product is reduced as much as possible.

Description

technical field [0001] The invention relates to an oil shale dry distillation furnace, in particular to a powdery oil shale dry distillation furnace. Background technique [0002] With the increasing shortage of oil resources in the world, shale oil as a substitute for oil has been paid more and more attention by countries all over the world. Shale oil will become a new energy source that countries are vying to develop in the 21st century. my country's oil shale resources are very rich, and the total reserves occupy the third place in the world. They are mainly distributed in Jilin and Fushun in the northeast, Maoming in Guangdong, and Inner Mongolia in Xinjiang. The estimated resources of oil shale with an oil content of 5%-10% are 260 billion tons, more than 10% of the predicted oil shale resources are 1260 tons. [0003] Oil shale dry distillation refers to the process of heating oil shale to the dry distillation temperature under the condition of isolation of air, and se...
