Left and right (for Fig. 1) both sides of passage 31, service channel 39 and oil gas concentrate passage 30 in vertical (relative to Fig. 1
For) set.
As can be seen that in the present embodiment, the air in the first tunnel 1 is enabled to preferably to convey by service channel 39
To in each destructive distillation passage 31, concentrate passage 30 can be by the shale oil in each destructive distillation passage 31 and gaseous mixture more by oil gas
It is delivered to well in the second tunnel 2, and the distribution of destructive distillation unit 3 is more planned, in order, can be fully to oil shale 4
Carry out liquefaction.
With continued reference to Fig. 1, in above-described embodiment, the both ends of service channel 39 respectively with 2 phase of the first tunnel 1 and the second tunnel
Connection, the first end of each destructive distillation passage 31 are connected with service channel 39.Specifically, service channel 39 is placed in the first tunnel 1
Horizontal segment and the second tunnel 2 horizontal segment between.
As can be seen that in the present embodiment, the setting of service channel 39, easy to the construction of service channel 39.
With continued reference to Fig. 1, in the various embodiments described above, destructive distillation unit 3 is at least two, between two neighboring destructive distillation unit 3
With pre-determined distance.Specifically, the quantity of destructive distillation unit 3 can be set according to actual conditions, and the structure of each destructive distillation unit 3 is equal
Can be identical, above-mentioned each structure is may each comprise in each destructive distillation unit 3.Between two neighboring destructive distillation unit 3 it is default away from
From can be determined according to actual conditions, the present embodiment does not do this any restrictions.
As can be seen that in the present embodiment, by setting at least two destructive distillation units 3, each destructive distillation unit 3 carries out oily page
The liquefaction of rock 4, can effectively improve the liquefaction efficiency and yield of oil shale.
In conclusion the destructive distillation of oil shale 4 is carried out in underground, carry out ground again without being exploited oil shale 4 to ground
Upper destructive distillation, takes a large amount of soils in this way, avoiding, greatly reduces exploitation workload, shorten the construction period, also, pass through
Air is in contact with oil shale 4 broken in advance, and the heat produced using oil shale own combustion is carried out destructive distillation and produces shale
Oil, it is cost-effective without large-scale distillation apparatus, heat source is provided without the external world, saves the energy, also, heating time is saved, contracting
The short liquefaction cycle, meanwhile, environmental pollution is small, effectively environmental protection, and, oil shale 4 need to only be crushed in advance
, thus the oil shale 4 of any granularity is used, use scope is expanded, the oil shale underground liquefaction system structure letter
It is single, it is convenient to carry out.
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
New spirit and scope.If in this way, these modifications and variations of the utility model belong to the utility model claims and
