Abstract
The invention provides a small-particle dry distillation technological process, wherein the dry distillation process is accomplished through dehydration/preheating, blending of hot ashes, dry distillation, cooling, combustion of the carbon residue, and collection of the hot ashes, each of which is performed through an individual machine respectively. A hot ash circulation loop is arranged on a feed end and a discharge end of a rotary gas retort, the hot ashes in the hot ash circulation loop are utilized as dry distillation transmission media. The volume of the circulated hot ashes can be altered through adjustment of the angle of a distributing board of a hot ash distributor. The carbon residue in the hot ashes is burnt in the circulation loop, which makes the hot ashes obtain very high temperature. The technological process is characterized in high heat exchange rate, quick heat transmission, small granularity of the treated material, simple operation, convenient maintenance of the individual machine, high running efficiency and long service life of the equipment, etc. The technological process accomplishes the effect of high utilization rate of the raw material and saving water resource.
Description
Affiliated technical field
The present invention relates to a kind of unconventional energy resource development field technological process of production, is a kind of technical process that oil is carried in oil-sand, greasy filth, resinous shale or the dry distillation of coal that is used for specifically.
Background technology
It is main that domestic existing destructive distillation oil extracting process generally adopts the vertical heater distillation process.The vertical heater distillation process requires very high to raw material granularity, can only the above particulate material of destructive distillation 10mm, and about 1/4th small-particle raw material seriously causes the waste of environmental pollution and resource as offal treatment.The deslagging of vertical heater distillation process consumes big water gaging in addition, causes the waste of water resources and water to pollute.Though external existing horizontal stove destructive distillation is carried oil tech and can be handled the small-particle raw material, because horizontal stove internal structure complexity, the stove internal fault is many, and maintenance difficulty is big, and operation rate is lower, is difficult to satisfy the suitability for industrialized production requirement.
Summary of the invention
For overcome the unsuitable destructive distillation small particles material of existing distillation apparatus, get rid of stove internal fault difficulty, maintenance difficulty is big, operation factor is low and the with serious pollution deficiency of water, the invention provides a kind of granule destructive distillation technology, this granule destructive distillation technology can not only the destructive distillation small particles material, and the energy maintenance difficulty is little, the operation factor height is realized anhydrous destructive distillation.
The technical solution adopted for the present invention to solve the technical problems is: by turning round preheating oven, rotary dry distillation stove, turning round the typical process flow that cooler is connected into.Be that between furnace and the revolution cooler heat ash being set sprays calcinatory, the whirlwind grey collector of heat and hot ash stream device.Make the circulation of rotary dry distillation stokehold after heat ash; Hot ash and mixing of materials before gas retort, hot ash stream device connect with mixing bunker and revolution cooler respectively, thereby have realized material preheating, hot grey mixing of materials, destructive distillation, carbon residue burning and residue refrigerative process.
Principle of work (see figure 1) of the present invention is: the small-particle raw material enters transfer roller 2 to opening for feed 3 from spout 1, enters in the revolution preheating oven 5 to dewater and preheating from opening for feed 3.After raw material preheating reaches certain temperature, enter scale 7 meterings and 9 imports of feeding lift from air inlet discharging cover 6, lift 9 rises to predetermined height with the material after the preheating, and enters the grey mixing bunker 17 of material by preheating discharge tube 10, and lock wind bleeder valve 11 is arranged at the bottom of preheating discharge tube 10.Raw material after the preheating in the grey mixing bunker 17 of material with reach higher temperature after the heat ash that comes self-heating ash discharge tube 12 mixes and enter the rotary dry distillation stove 18 of expecting grey mixing bunker 17 bottoms, in rotary dry distillation stove 18, stop certain hour, and obtaining abundant destructive distillation, the destructive distillation residue enters slag gas separator cartridge 20 under the rotary motive power effect of rotary dry distillation stove 18.The oil gas that destructive distillation produces in rotary dry distillation stove 18 also enters slag gas separator cartridge 20, and discharges other collection devices by the oil gas vent 19 on slag gas separator cartridge 20 tops.Residue in the slag gas separator cartridge 20 enters in the spray combustion tower 21 by the residue discharge tube 22 of bottom, and lock wind bleeder valve 23 is arranged at residue discharge tube 22 bottoms.Residue enters spray combustion tower 21 backs and is sprayed lifting by the hot high-speed air from gas ejector pipe 26, rises to top from spray combustion tower 21 bottoms and enter the grey collector 13 of whirlwind heat by the grey transfer lime 15 of heat to be collected.Carbon residue in the residue contacts with warm air in spraying lifting process and burns, and the residue temperature is increased substantially.Collected in the grey collector 13 of. whirlwind heat is the elevated temperature heat ash,. hot ash stream device 13a is arranged at the grey collector of whirlwind heat 13 bottoms, the hot ash that hot ash stream device 13a collects the grey collector 13 of whirlwind heat is distributed into two portions, a part enters the grey mixing bunker 17 of material by the grey discharge tube 12 of heat, another part enters revolution cooler 32 by the grey sub-material discharge tube 14 of heat, the heat ash that enters revolution cooler 32 carries out heat exchange with air, become the lower slag of temperature, under the rotary motive power of revolution cooler 32 drives outside the other end discharge machine of revolution cooler 32, the warm air that enters revolution cooler 32 becomes high temperature air through heat exchange and enters dust-precipitator 29 and carry out udst separation, by heating pipe 28, and under blower fan 27 effects, send into combustion chamber 25 through gas ejector pipe 26, be used for the burning that spray combustion tower 21 residues spray lifting and carbon residue.On the spray combustion tower 21 on the top of combustion chamber 25 stoker 24 is installed, stoker 24 uses when total system starts.Rotary dry distillation stove 18, spray combustion tower 21, whirlwind heat grey collector 13, hot ash stream device 13a and expect between the grey mixing bunker that 17 connect into circulation loop by the grey discharge tube 12 of heat, residue discharge tube 22 and pipeline thermal ash transfer lime 15.
The invention has the beneficial effects as follows, processing unit is formed with a plurality of independent meanss, equipment finishes independently respectively that preheating, destructive distillation, carbon residue burning, heat ash are collected, the material ash mixes and the residue cooling, characteristics such as unit is simple in structure, control is easy, easy to maintenance, operation factor height; Be fit to the destructive distillation small particles material; Realize anhydrous destructive distillation.
