Description
Technical field
The present invention relates to the carbon-calcining rotary kiln production technique of the plain production field of charcoal, particularly relate to a kind of carbon rotary kiln high temperature and forge back burnt method of cooling and device.
Background technology
Calcining petroleum coke is the important step in the plain production process of charcoal, its effect is that the plain raw material → refinery coke produced of charcoal is carried out high-temperature calcination in rotary kiln, to get rid of contained fugitive constituent in the refinery coke, increase its true specific gravity, reduce it than resistance, make every physical and chemical index of after-smithing petroleum coke meet carbon product produce in technology to the requirement of raw material.
Carbon-calcining rotary kiln is the major equipment of present calcined petroleum coke, its calcining temperature up to 1350 ℃ about.In process of production, finishing incinerating, to forge the back burnt when the kiln hood chute is discharged, and its temperature is all more than 1000 ℃, and its heat that carries is very considerable.In order to prevent that high temperature from forging the burnt oxidation in air in back, the high temperature of discharging from the kiln hood chute is forged back Jiao need force cooling fast.At present the method for cooling that adopts is: high temperature is forged the back is burnt to import the revolution cooling cylinder by chute, and sprayed at cooling cylinder external use water coolant, the back is burnt when cooling cylinder is discharged when forging, and reaches inoxidizable temperature substantially.The heated water coolant in spray back will be through recycling after the cooling tower cooling, and this part heat has then progressively been diffused in the atmosphere.This method of cooling has the shortcoming of following several respects: 1, be difficult to reach evenly owing to the external spraying cooling water of cooling cylinder, so cooling efficiency is low; 2, can not realize and atmospheric isolation owing to cooling cylinder, in process of cooling, still can produce oxidation, consequently both increase ash burnt after forging, influenced quality burnt after forging, reduce the yield of Jiao after forging again so can't avoid high temperature to forge back Jiao; 3, in the spray process of cooling,,, be unfavorable for the saving of water resources so water consumption is big because a large amount of cooling water evaporation loses; 4, long-continued spray cooling, severe oxidation corrosion cooling apparatus has worsened the operating environment condition simultaneously; 5, the water coolant behind spray is subjected to severe contamination, will increase the pollution treatment processing costs; 6, special cooling water recirculation system and the water processing establishment that is provided with need take certain land resources; 7, the residual heat resources that Jiao carried after high temperature was forged are wasted, and run counter to the recycling economy principle of energy-saving and emission-reduction.
Summary of the invention
The present invention provides a kind of carbon rotary kiln high temperature to forge back burnt method of cooling and device in order to solve the problems of the technologies described above, purpose is that burnt cooling performance was poor after high temperature was forged in the solution calcining petroleum coke process, high-temperature material produces oxidation, cooling water resources waste, operating environment inclement condition, water is seriously polluted, cooling water circulation and treatment system cost height, high temperature are forged the problem that the burnt entrained heat in back is wasted.
Be achieved in that in order to solve the problems of the technologies described above the present invention a kind of carbon rotary kiln high temperature forges the burnt method of cooling in back, comprise the steps: that high temperature forges the burnt chute through revolution kiln hood bottom in back and import cooling jacket; Through importing to the discharge apparatus discharge by cooling jacket behind the row down continuously.
Water coolant in the described cooling jacket enters its interlayer cavity from the cooling water inlet of cooling jacket bottom.
The steam that produces after cooling water heat burnt and that cooling jacket is interior exchanged after described high temperature was forged enters the gas upcast from the vapour outlet on cooling jacket top.
Described gas upcast enters in the high-order drum, from the steam outlet output of high-order drum.
Water of condensation after separating in the described high-order drum is in downtake is back to cooling jacket.
A kind of carbon rotary kiln high temperature is forged the burnt refrigerating unit in back, be made of following structure: cooling jacket is communicated with rotary kiln end by the kiln hood chute, be provided with discharge apparatus below cooling jacket, be provided with cooling water inlet and vapour outlet on cooling jacket, cold water is in the cavity of cooling jacket.
Described cooling water inlet is located at the bottom of cooling jacket.
Described vapour outlet is located at the top of cooling jacket.
Described cooling water inlet is connected with cold water pipe.
Described vapour outlet is connected with the gas upcast.
The top of described rotary kiln is provided with high-order drum, and high-order drum is communicated with the gas upcast.
Described high-order drum is connected with steam outlet.
Described high-order drum is provided with the water of condensation downtake.
Described water of condensation downtake is connected with cold water pipe.
Described cold water is soft water.
Described cooling jacket is a joint or a more piece.
The present invention has the following advantages:
1, owing to be full of water coolant in the cooling jacket interlayer cavity, its top is steam to be overflowed, and the high-temperature material heat conducts soon in the cooling jacket, so forge the burnt good cooling results in back, efficient height in the cover.
2, because the kiln hood chute has the effect of material envelope, can to make high temperature in the cooling jacket forge the back burnt isolated with air fully, avoided forging the burnt oxidation in back in the process of cooling, improved the yield of forging back Jiao, reduced and forged the burnt ash oontent in back, helped improving the carbonaceous product quality.
3, because water coolant and the steam that produced are in the closed state current downflow, can avoid water resource waste, stop the water that the spray type of cooling brings simultaneously and polluted.
4, cancel cooling cylinder, can make the cooling apparatus volume just little, saved the power consumption that the cooling cylinder operation is produced simultaneously.
5, cancel water treatment system, saved the water pollution control expense, and saved the land area of factory.
6, high temperature is forged the burnt entrained most of heat in back and will be obtained recycling, and can be factory corresponding thermal source is provided, and meets the recycling economy principle of energy-saving and emission-reduction.
