Description
Technical field
The present invention relates to metallurgical coking industry coal tar processing route field, specifically, be the oil product preparation production equipment and the production technique thereof of production process in the middle of the coal tar processing unit (plant), be applicable to the technological transformation and the new project of metallurgical coking industry coal tar processing industry.
Background technology
The oil product preparation production technological process of production of existing coal tar processing industry generally is that mid-temperature pitch and carbolineum enter distributing groove respectively both at home and abroad, on distributing groove, be provided with mechanical stirrer, when producing, start agitator, allow the mid-temperature pitch and the carbolineum that enter distributing groove mix, quality according to oil product, adjust mid-temperature pitch and carbolineum inlet respectively, the oil gas that produces when it joins oil, directly enter the exhaust cleaning system through bleeder, when inlet amount is big, produce a large amount of oil gas, can not all enter diffusion system, the flange connections of part oil gas slave unit and stirrer shaft sealing place are revealed, and pollute surrounding environment; Enter the flue gas of diffusion system because temperature is higher, the washing oil temperature of exhaust system is raise, also follow a large amount of carbolineums to enter cleaning system, make the exhaust cleaning system clean decrease in efficiency, show as exhaust and clean tower exhaust band oil, the oil gas that produces when joining oil for minimizing, some distributing devices have increased pitch vaporization and condensation water cooler before the mid-temperature pitch pipeline enters distributing groove, distributing groove is provided with 2 covers usually.
Above-mentioned oil product compounding and production process flow process is distributed a large amount of flue gas (oil gas) around device, its reason mainly is:
(a) mid-temperature pitch is can not the refrigerative temperature too low, and misoperation makes the pitch blocking pipe easily;
(b) owing to have mechanical stirring device on the equipment, agitator runs to its packing seal place fume leakage of certain hour;
(c) for guaranteeing the repair and maintenance of agitator, the big flange of section steel manufacture is adopted at the equipment top, is connected with bolt, asbestos plate pad with top board because equipment is bigger, all be the in-situ processing making, during production all around in various degree emit flue gas;
(d) temperature Gao Shiyi causes bumping, from flange joint face and stirrer shaft sealing leakage of oil, causes when serious and sends out oil leak accident;
(e) flue-gas temperature height has greatlyyer, makes exhaust cleaning system decrease in efficiency, and after running for some time, the waste gas band oil that gas shaft is discharged is around floating down on the wind
Oil product preparation production process in now at present both at home and abroad all coal tar processing unit (plant)s also have well to solve the smog of joining oil generation around device when producing, in contaminate environment also with the damage of carbolineum raw material; Agitator not only consumes a large amount of energy in condition of high temperature running for a long time, also want the regular maintenance agitator, we can say, current all coal tar processing enterprises are perplexed by the pollution of oil product preparation production equipment all when producing, operator not only are subjected to smog, mist of oil infringement when operation, also have certain risk.
There are following defective in the oil product blending process and the equipment of each manufacturing enterprise's use now:
(a) smog is big, contaminate environment, infringement operator physical and mental health;
(b) the oil loss amount is big, and production cost increases;
(c) operation makes agitator current consumption big, and it is higher to consume energy;
(d) maintenance of the equipment is frequent, and labor intensity of operating staff is big;
(e) mishandle can cause the pitch bumping, and accident can cause casualties when serious.
Therefore, in the coal tar course of processing, press for and improve existing oil product compounding and production process, make new oil product compounding and production process be more suitable for coal tar processing needs, reduce of the pollution of coal tar processing unit (plant) environment.Be badly in need of design and have that technical process is simple, investment is low, pollution-free, the novel widely oil product preparation of suitability production equipment.
Summary of the invention
The object of the invention provides the production technique of oil product preparation in a kind of coal tar course of processing, to realize reducing the unit consumption of product, increases carbon black oil or oil fuel product yield, and the purpose of improving the quality of products improves the business economic benefit.The present invention also is that the coal tar processing industry reduces environmental pollution, the new technology of energy efficiency.
The main points of explained hereafter flow process of the present invention are thoroughly to solve the problem of environmental pollution that the oil product preparation is produced, and are energy-saving and cost-reducing, reduce project investment.
Another object of the present invention provides a cover and is used for described coal tar course of processing oil product compounding and production process and guarantees pollution-free, the environmental protection that has no irritating odor, take up an area of few, less investment, oil product preparation production equipment simple to operate, that labour intensity is low, safe.
