Description
Technical field
The utility model relates to the production equipment of a kind of carbon black production device, particularly a kind of semi-reinforcing hydrocarbon black.
Background technology
Semi-reinforcing hydrocarbon black is to take Sweet natural gas as raw material is at anoxic incomplete combustion, and part Sweet natural gas generates 1400 ℃ to 1100 ℃ cracking, and this carbon black has unique quality, the purposes widely in fields such as rubber, machinery, metallurgy, plastics.
At present, the key equipment Reaktionsofen of all production semi-reinforcing hydrocarbon blacks, generally adopt double-burner structure, as depicted in figs. 1 and 2, comprise successively burner 1, 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 Imported gas 5, air intlet 6 and fuel nozzle 7, for the Sweet natural gas of fuel being provided and treating that the Sweet natural gas of cracking all enters from Imported gas 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) through nozzles, spray into burner hearth 2, limit burning limit cracking, high-temperature gas mixture enters flue reaction chamber 3 through junctions, continue to spray quenched water termination reaction after scission reaction, its single furnace output only has 210kg/h, and exist adjustment quality product means few, energy consumption is high, residual heat integrative utilizes the not high defect of degree.
Summary of the invention
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide the novel semi-reinforcing hydrocarbon black Reaktionsofen that a kind of output is high, energy consumption is low.
The technical solution adopted in the utility model is such: a kind of semi-reinforcing hydrocarbon black Reaktionsofen, 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 fuel natural gas import, fuel nozzle and air intlet, at described flue reaction chamber back segment, are provided with quenched water import.
As preferably: described two identical combustion chambers are arranged with burner hearth centrosymmetry.Such layout makes combustion gas flowing tangentially enter burner hearth, and like this, combustion gas flowing becomes rotation further mixing and burning at freeze profile.
The application is designed to four-part form by whole Reaktionsofen: it is low that semi-reinforcing hydrocarbon black production has combustion air temperature, the feature that combustion of natural gas velocity of diffusion is slow, for Sweet natural gas is fully burnt, must there be sufficient space and diffusion time, therefore, present inventor is designed to two by combustion chamber (being first paragraph), fuel gas tangentially enters burner hearth (being second segment), fuel gas is after burner hearth fully burns, produce 1450 ℃ to 1500 ℃ high-temperature gases by trunnion (the 3rd section), enter flue reaction chamber (the 4th section) and proceed cracking, finally with water coolant chilling, stop scission reaction, due to sufficient combustion, sufficient reacting, so output improves greatly, and energy consumption is corresponding reduction also.
As preferably: arrange at described trunnion place and need cracking stock Imported gas.
Owing to having set up and having treated cracking stock Imported gas at trunnion place, fuel gas is after burner hearth fully burns, produce 1450 ℃ to 1500 ℃ high-temperature gases by trunnion (the 3rd section), entering trunnion mixes with the cracking stock Sweet natural gas for the treatment of of injecting at a high speed, under high-temperature high-speed airflow effect, make to treat cracking stock Sweet natural gas and high-temperature gas short mix and cracking.Be fuel gas (entering from fuel natural gas import) and treat that cracking stock Sweet natural gas (from treating that cracking stock Imported gas enters) enters respectively Reaktionsofen in different positions, on the one hand because mixing, the single furnace output of temperature height is greatly enhanced; On the other hand, so be mainly used in providing heat not high to its quality requirements because of the fuel natural gas entering from inlet mouth; In addition, can adopt the gas in other sources as fuel, for further making full use of Energy Consumption In A Typical, provide possibility; Again, thus can adjust air and fuel gas ratio and treat that cracking stock Sweet natural gas ratio can conveniently adjust quality product and kind.
As preferably: described in treat that cracking stock Imported gas is 1 or several.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: can make fuel gas fully burn and make to treat the abundant scission reaction of cracking stock Sweet natural gas, greatly improved output, can reduce energy consumption simultaneously, the convenient quality and variety of adjusting product, has good economic benefit and social enviroment protection benefit.
