Abstract

An oil shale refining, power generating and cement tri-generating integrated device smashes the oil shale ore to 0 to 8mm and sends the oil shale ore to a carbonization device via a distributor to prepare the oil shale and fuel gas. The generated half coking castoff of oil shale with high temperature enters a circulating fluidized bed boiler via a conveyor to burn. The generated heat is converted to steam which can be applied to generating power, supplying heat and extracting high temperature soot at 550 degree C to 750 degree C from the circulating fluidized bed to enter the carbonization device as carbonization heat medium; slag discharged from the circulating fluidized bed boiler and part of discharged ash of the separator as well as precipitator dust directly enter a calciner for calcining, generating cement. The invention applies heat energy synthetically, which saves energy and protects environment.

Description

Oil shale oil-refining, generating and cement triple production integrated device

Technical field

The present invention relates to a kind of oil shale oil-refining, generating and cement triple production integrated device.

Background technology

The comprehensive utilization of oil refining, boiler combustion and the cement building material of resinous shale is at present finished in gas retort, circular fluid bed and cement building material factory respectively, be to finish by three covering devices independently, do not become one, so just have following problem: the oil refining gas retort of resinous shale can't directly be handled the 0-8mm oil shale particle; The semicoke that gas retort is discharged can't directly enter burning in circulating fluid bed boiler, needs intercooling with broken, the comprehensive utilization weak effect of resinous shale; The lime-ash of discharging from circulating fluidized bed can only making cement ginseng and material, can not directly produce cement of high index as cement clinker; Gas retort, circular fluid bed and cement kiln are relatively independent systems, do not realize coproduction, need intermediate transportation, so energy consumption is big, investment is big.

Summary of the invention

The purpose of this invention is to provide a kind of oil shale oil-refining, generating and cement triple production integrated device, it can get final product save energy with oil refining, the burning in circulating fluid bed boiler generating and cement triple production integrated finishing of resinous shale, reaches environment protecting again.

The present invention is achieved like this, it comprises shredding unit, destructive distillation device, condensing works, circular fluid bed, calcining furnace, variable valve, fly-ash separator, pulverizing mill, it is characterized in that shredding unit connects destructive distillation device, destructive distillation device connects shale oil condensing works and circular fluid bed, circular fluid bed connects fly-ash separator, destructive distillation device and calcining furnace, calcining furnace connects fly-ash separator and circular fluid bed, is connected with variable valve and separator at circular fluid bed and destructive distillation device and circular fluid bed and fly-ash separator.

Technique effect of the present invention is: the oil refining destructive distillation device can directly be handled 0-8mm oil page or leaf particle, produce shale oil and combustion gas, high temperature semicoke waste directly enters boiler combustion, the heat that produces is converted into steam and is used for generating electricity and heat supply, high-temperature flue gas enters destructive distillation device as the destructive distillation thermal medium, flue gas after the destructive distillation is back boiler again, and the high-temperature ash that boiler is discharged and the ash discharge of fly-ash separator directly enter calcining furnace and calcine production cement, promptly energy-conservation environmental protection again.

Description of drawings

Fig. 1 is a fundamental diagram of the present invention.

Embodiment

As shown in Figure 1, the present invention includes shredding unit 1, destructive distillation device 2, condensing works 3, circular fluid bed 4, calcining furnace 8, variable valve 5, fly-ash separator 7, pulverizing mill 9 features is that shredding unit 1 connects destructive distillation device 2, destructive distillation device 2 connects shale oil condensing works 3 and circular fluid bed 4, circular fluid bed 4 connects fly-ash separator 7, destructive distillation device 2 and calcining furnace 8, calcining furnace 8 connects fly-ash separators 7 and circular fluid beds 4, in being connected of circular fluid bed 4 and destructive distillation device 2 and circular fluid bed 4 and fly-ash separator 7 variable valve 5 is arranged.During use, resinous shale through shredding unit 1 broken be sized to 0 ~ 8mm after, send in preposition (or side) destructive distillation device 2 of circular fluid bed 4 and carry out destructive distillation, 450 ~ 600 ℃ of pyrolysis temperatures, the destructive distillation gas that destructive distillation produces enters condensing works 3, isolates shale oil and combustion gas; The high temperature that is produced in the oil shale distillation process (500 ~ 750 ℃) semicoke directly enters in the circular fluid bed 4 and so burns, and temperature of combustion is 750-950 ℃, and the heat of generation is converted into steam, can be used to generating and heat supply; 550 ~ 750 ℃ high temperature position is extracted flue gas out and is entered in the retort section of destructive distillation device 2 as the destructive distillation thermal medium from circular fluid bed 4, and 500 ~ 600 ℃ of flue gases after the destructive distillation return in the circular fluid bed 4 by flue.Boiler enters the preheating section that 150 ~ 250 ℃ partial fume before the fly-ash separator is introduced in the destructive distillation device 2 by variable valve 5, and resinous shale is carried out preheating; Last smoke evacuation enters fly-ash separator and enters chimney again after mixing; 700 ~ 850 ℃ of ash discharges of part of separator at the bottom of discharge from circular fluid bed 750 ~ 950 ℃ slag and the circular fluid bed and fly-ash separator ash discharge enter calcining furnace respectively and calcine, calcine required fuel and coagulate the combustible gas of discharging in the device 3,1100 ~ 1300 ℃ of calcining temperatures for destructive distillation air cooling.
