Description
Technical field
The present invention relates to a kind of production of carbon black equipment and method, equipment and method that particularly a kind of semi-reinforcing hydrocarbon black is produced.
Background technology
Semi-reinforcing hydrocarbon black be with the Sweet natural gas be raw material at the anoxic incomplete combustion, the part Sweet natural gas generates 1400 ℃ to 1100 ℃ cracking, this carbon black has unique quality, the purposes widely in fields such as rubber, machinery, metallurgy, plastics.
At present, all produce the key equipment Reaktionsofen of semi-reinforcing hydrocarbon black, generally adopt the twin furnace header structure, as depicted in figs. 1 and 2, comprise burner 1 successively, burner hearth 2 and flue reaction chamber 3, flue reaction chamber 3 back segments are provided with quenched water import 4, each burner 1 front end is provided with Sweet natural gas import 5, air intlet 6 and fuel nozzle 7, being used to provides the Sweet natural gas of fuel and treats that the cracked Sweet natural gas all enters from Sweet natural gas import 5, and be same Sweet natural gas, and combustion air tangentially rotates into burner hearth 2 from air intlet 6, all natural gas (raw natural gas, fuel natural gas) sprays into burner hearth 2 through nozzles, the cracking while burning, high-temperature gas mixture enters flue reaction chamber 3 through the junctions, continue to spray the quenched water termination reaction after the scission reaction, its single furnace output has only 210kg/h, and exists adjustment quality product means few, the energy consumption height, residual heat integrative utilizes the not high defective of degree.
In addition, the fuel source of producing semi-reinforcing hydrocarbon black at present mainly is a Sweet natural gas, its cost is higher relatively, and Sweet natural gas belongs to Nonrenewable resources, and the refined carat of carbon black company limited in Xinjiang is engaged in semi-reinforcing hydrocarbon black production, newly-built again 2000t/a thermals production line for many years, thermal process is produced carbon black, can produce a large amount of hydrogen rich gas gas, i.e. the application's described " thermal black cracking hydrogen ", its calorific value is at 14000KJ/M
3To 15000KJ/M
3, temporarily do not have fine utilization.
Summary of the invention
One of goal of the invention of the present invention is: at the problem of above-mentioned existence, provide a kind of hydrogen rich gas gas that produces when thermal process is produced carbon black that can make full use of to act as a fuel and carry out the equipment that semi-reinforcing hydrocarbon black is produced.
The technical solution used in the present invention is such: comprise the combustion chamber, burner hearth, trunnion and the flue reaction chamber that connect successively, described combustion chamber is identical two, described two identical chamber front ends are provided with inlet mouth, fuel nozzle and air intlet, are provided with the quenched water import at described flue reaction chamber back segment.
As preferably: described two identical combustion chambers think that the burner hearth centrosymmetry arranges.
As preferably: be provided with at described trunnion place and remain the import of cracking stock Sweet natural gas.
Further: describedly treat that the import of cracking stock Sweet natural gas is 1 or several.
The application is a four-part form with the entire reaction equipment design: it is low that semi-reinforcing hydrocarbon black production has combustion air temperature, for hydrogen is fully burnt, enough spaces and diffusion time must be arranged, therefore, the present inventor is designed to two with combustion chamber (promptly first section), fuel gas tangentially enters burner hearth (promptly second section), fuel gas is after burner hearth fully burns, produce 1450 ℃ to 1500 ℃ high-temperature gases by trunnion (promptly the 3rd section), enter flue reaction chamber (promptly the 4th section) and proceed cracking, stop scission reaction with the water coolant chilling at last, because sufficient combustion, sufficient reacting, so output improves greatly, and the also corresponding reduction of energy consumption;
Treat the import of cracking stock Sweet natural gas owing to having set up at the trunnion place, fuel gas is after burner hearth fully burns, produce 1450 ℃ to 1500 ℃ high-temperature gases by trunnion (promptly the 3rd section), entering trunnion mixes with the cracking stock Sweet natural gas of injecting at a high speed for the treatment of, under the effect of high temperature and high speed air-flow, make and treat cracking stock Sweet natural gas and high-temperature gas short mix and cracking.Be fuel gas (entering) and treat that cracking stock Sweet natural gas (entering from treating the import of cracking stock Sweet natural gas) advances Reaktionsofen respectively in different positions from inlet mouth, on the one hand because of mix, the single furnace output of temperature height is greatly enhanced; On the other hand, so provide heat not high to its quality requirements because of the fuel hydrogen that enters from inlet mouth is mainly used in, act as a fuel thereby can make full use of the hydrogen rich gas gas that produces when thermal process is produced carbon black, make full use of the tail gas energy when having saved natural gas source and further cut down the consumption of energy; Once more, thus can adjust air and fuel gas ratio and treat that cracking stock Sweet natural gas ratio can conveniently adjust quality product and kind.
Two of purpose of the present invention is, a kind of method of the hydrogen rich gas gas generation semi-reinforcing hydrocarbon black that produces when utilizing thermal process to produce carbon black is provided, the technical characterictic that adopts is, adopt above-mentioned equipment to produce, the black cracking hydrogen of hot tearing black wood charcoal tangentially enters burner hearth from inlet mouth, combustion air enters from air scoop, the black cracking hydrogen of hot tearing black wood charcoal is after the burner hearth burning, the gas that produces passes through trunnion, treat that with what treat that the import of cracking stock Sweet natural gas enters the cracking stock Sweet natural gas enters the flue reaction chamber and proceeds cracking, stop scission reaction with the water coolant chilling at last.
As preferably: the black cracking hydrogen of hot tearing black wood charcoal is after the burner hearth burning, and the gas of generation passes through trunnion with 100m/s to 200m/s speed.Such speed helps mixing and cracking with raw natural gas.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows: fuel gas is fully burnt and make and treat the abundant scission reaction of cracking stock Sweet natural gas, output can improve more than 60%, can cut down the consumption of energy simultaneously the convenient quality and variety of adjusting product; In addition, can utilize the black cracking hydrogen of hot tearing black wood charcoal to act as a fuel, have good economic benefit and social enviroment protection benefit.
