Abstract
This invention discloses a process for producing carbon black from oven coal gas instead of fuel oil. The process comprises: treating collected oven coal gas with a water-sealing apparatus, adjusting the pressure by a coal gas fan and a pressure adjusting valve, passing through a flow meter, an automatic flow adjusting valve and a check valve, mixing oven coal gas with air at a certain ratio, introducing into a combustion furnace, combusting, sending the heat generated during combustion to a throat to atomize raw oil there, sending atomized raw oil to a reaction furnace, pyrolyzing to obtain carbon black, cooling, collecting, transporting, granulating, and packaging. The method can effectively prolong the service life of combustion furnace, and has such advantages as high process stability and high carbon black quality.
Description
Technical field
The present invention relates to a kind of production sooty technology, refer to especially produce sooty technology with the heat supply of coke-oven gas alternative fuel oil.
Background technology
All the time, the sooty production technology is to use fuel oil combustion to provide heat to make atomizing raw materials such as coal tar, ethylene bottom oil, carbolineum, vaporization back carry out scission reaction in Reaktionsofen, makes through technologies such as cooling collection, conveying, granulations again.Because factors such as fuel oil combustion instability cause reduce problems such as technology stability difference and carbon black mass rank difference the work-ing life of roasting kiln.
Summary of the invention
The technical problem to be solved in the present invention is to adopt unnecessary coke-oven gas alternative fuel oil in the roasting kiln internal combustion, so that continual and steady heat to be provided on the basis of above-mentioned technology.Improve the work-ing life and the technology stability of roasting kiln, improve the quality of carbon black products.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the technology of producing carbon black by using coke oven gas instead of fuel oil, comprise last stage processing step and latter stage processing step, described latter stage processing step is: the stock oil after stock oil that the heat that fuel is produced after burning enters trunnion, add at the trunnion place and atomizing, the atomizing enters Reaktionsofen and carries out scission reaction, and the carbon black that the reaction back produces carries out granulation and packing through cooling, after collecting, carrying.In the last stage processing step with coke-oven gas alternative fuel oil; Described last stage processing step is as follows: earlier with the coke-oven gas collected after water seal arrangement is handled, through gas fan, automatic pressure regulating valve pressure, again through strapping table, motor valve, vacuum breaker, enter the roasting kiln burning according to certain ratio after with coke-oven gas and air mixed again.Respectively be connected in series a maintenance valve at described gas fan, pressure automatic regulating valve, motor valve, vacuum breaker two ends, and at motor valve, a vacuum breaker two ends make-up valve in parallel, its objective is to guarantee when maintenance also air feed continuously.

Embodiment
Fig. 1 is existing sooty technological process of production figure, after cooperating according to a certain percentage, oil fuel and air enter the roasting kiln burning, heat after the burning enters trunnion, make the stock oil that adds at the trunnion place atomize, vaporize, produce carbon black and combustion residual air and splitting gas after in Reaktionsofen, producing scission reaction, cool off, collect, carry last granulation, packaging final prod through refrigerating unit again.
Fig. 2 is coke-oven gas processing technological flow figure, and the technology of producing carbon black by using coke oven gas instead of fuel oil comprises last stage processing step and latter stage processing step, is with coke-oven gas alternative fuel oil in the last stage processing step; Described last stage processing step is as follows: earlier with the coke-oven gas 1 collected after water seal arrangement 2 is handled, regulate pressure through gas fan 3, pressure automatic regulating valve 4, again through strapping table 5, motor valve 6, vacuum breaker 7, enter the roasting kiln burning according to certain ratio after with coke-oven gas and air mixed again.Described latter stage processing step is: the stock oil after stock oil that the heat that coke-oven gas is produced after burning enters trunnion, add at the trunnion place and atomizing, the atomizing enters Reaktionsofen and carries out scission reaction, and the carbon black that the reaction back produces carries out granulation and packing through cooling, after collecting, carrying.
The present invention has guaranteed to provide continual and steady combustion gases to roasting kiln, reached the stable purpose of heat supply, thereby roasting kiln is prolonged more than four times work-ing life, combustion chamber furnace temperature temperature fluctuation when using oil fuel ± 50 ℃ reduce to ± 10 ℃, sooty iodine absorption value fluctuation range is narrowed down to ± 7g/kg by ± 10g/kg, improve the work-ing life and the technology stability of roasting kiln greatly, improved the sooty quality effectively.
Claims (1)
1. the technology of a producing carbon black by using coke oven gas instead of fuel oil, comprise last stage processing step and latter stage processing step, described latter stage processing step is: the heat that fuel is produced after burning enters trunnion, the stock oil after the stock oil of trunnion place adding also atomizes, atomizes enters Reaktionsofen and carries out scission reaction, the carbon black that the reaction back produces carries out granulation and packing after cooling off, collect, carrying, it is characterized in that: with coke-oven gas alternative fuel oil; Described last stage processing step is as follows: earlier with the coke-oven gas (1) collected after water seal arrangement (2) is handled, regulate pressure through gas fan (3), pressure automatic regulating valve (4), again through strapping table (5), motor valve (6), vacuum breaker (7), enter the roasting kiln burning according to certain ratio after with coke-oven gas and air mixed again.
