Description
The utility model relates to a kind of reactor for production of carbon black, particularly be a kind of all-metal construction reactor for production of carbon black.
At present the structure of the reactor for production of carbon black that uses is to build burner hearth by laying bricks or stones with refractory materials in the steel furnace shell, and the burning zone that temperature is high, trunnion section, conversion zone internal layer are built burner hearth with corundum castable, skin with the high-strength insulation refractory materials with high temperature resistant high-alumina corundum or corundum-chromium-zirconium composite refractory brick, middle level.The quench zone that temperature is lower, stay segment internal layer are total to the two-layer burner hearth of building by laying bricks or stones with corundum, skin with the high-strength insulation refractory materials.The disclosed reactor for production of carbon black of CN103599A be at the burning zone rear portion, trunnion section, conversion zone, quench zone front and rear portions be local jacket structured with metal water, uses water cooling.The burner hearth main body is still with refractory materials builds by laying bricks or stones.The Reaktionsofen of these structures all exists and protects that the logistics of thorax refractory materials scaling loss goes into influence in the carbon black smoke carbon black mass, work-ing life is short, maintenance time is grown, influence the production line operation ratio, water cooling chuck place partial heat energy is taken away by water, the problem that haves much room for improvement that heat-energy losses is big.
In view of above reason, the purpose of this utility model is can guarantee carbon black mass in order to provide a kind of, long service life, and maintenance cost is few, can guarantee the all-metal construction reactor for production of carbon black that the production line operation ratio is high.Another purpose of the present utility model is in order to provide a kind of heat energy utilization rate high all-metal construction reactor for production of carbon black.
The purpose of this utility model is achieved like this: the burning zone that contains inlet mouth that connects successively that useful refractory metal material is made in the utility model Reaktionsofen, the trunnion section cylindrical shell that contains the stock oil base, the conversion zone cylindrical shell, the quench zone cylindrical shell that contains the quenched water base, the stay segment cylindrical shell, burning zone comprises combustion outer case, place the full air film burner inner liner of combustion outer case, form bypass passage between burner inner liner and combustion outer case, the spray nozzle part that is contained in the nozzle burner assembly on the combustion outer case is contained in the burner inner liner front portion, the lighter for ignition that is contained on the combustion outer case communicates with burner inner liner, in the trunnion section, the conversion zone cylindrical shell, the quench zone cylindrical shell, there is the cooling air of containing to advance respectively on the stay segment cylindrical shell neighboring, the spiral cooling air jacket (referring to Fig. 1) of air outlet, there is the whirlpool that communicates with nozzle the burner inner liner front portion, whirlpool can make preheated air and atomized fuel reach best admixture, refractory metal material can be selected superalloy for use, as GH44.
Above-mentioned trunnion section barrel front end has air film hole; trunnion section periphery spreads hot ring plate (referring to Fig. 1, Fig. 3); some enters cooling air by trunnion section spiral cooling air jacket in the trunnion section cylindrical shell from trunnion section cylindrical shell forward air film hole; form one section air film along cylinder inboard wall; protection trunnion section cylindrical shell is by scaling loss, and is mixed into the conversion zone cylindrical shell with the flame gas of burning zone ejection and participates in cracking.
Above-mentioned trunnion section cylindrical shell, conversion zone cylindrical shell, quench zone cylindrical shell, place, stay segment cylindrical shell air outlet are provided with the return-air base respectively, there is the inlet pipe that contains cooling air return main seat that is connected with combustion outer case at the anterior inlet mouth of burning zone place, the airflow rectifier is arranged in the inlet pipe, and the return-air house steward who is connected with cooling air return main seat is communicated with the return-air base that each spiral cooling air puts respectively.(referring to Fig. 1～Fig. 4), cooling air is brought the heat energy that absorbs into burning zone, conversion zone, participation first and second burning as carrier again after cooling off each section cylindrical shell.
The utility model Reaktionsofen is installed on the Reaktionsofen seat by the bearing on each section, and its axial direction due can not be fixed, and guarantees that thermal expansion and the cold contraction of Reaktionsofen when blow-on, blowing out can move freely.
Referring to Fig. 1～Fig. 4, the air in the utility model Reaktionsofen is supplied with by the cooling blower of main air blower.The air that main air blower is supplied with merges and enter the inside and outside letter of burning zone road after rectification at inlet pipe and the cooling air that enters through the total base of cooling air return-air after the air preheater preheating.An air part that enters burning zone becomes the spiral fluidised form to enter in the burner inner liner from whirlpool, another part becomes air film fluidised form to enter burner inner liner internal combustion district with air film hole along burner inner liner head inwall from the gap of burner inner liner head, two portions air-flow merges forms inner by-pass, the tissue burning.Bypass passage between remaining air admission combustion outer case and burner inner liner; make and form an airflow thermofin between combustion outer case and the burner inner liner; the working temperature of combustion outer case cylindrical shell is reduced; simultaneously the bypass passage airflow some enter in the burner inner liner, form the air film of burner inner liner inwall by the jet degree of depth of design by the air film hole on the burner inner liner; this air film becomes the thermofin between combustion flame and burner inner liner cylindrical shell, and protection burner inner liner cylindrical shell can scaling loss.The air film air-flow is the air capacity of complementary tissue burning needs also.Bypass passage part air is mixed into the trunnion section and is mixed into conversion zone cracking generation carbon black with the atomized feed oil that is sprayed into by stock oil base place at burner inner liner nozzle place and flame gas.For the temperature of termination reaction and reduction carbon black gas, when carbon black gas flowed into quench zone, the cold water that sprays into atomizing from the quenched water base cooled off.Carbon black gas after the cooling is gone into air preheater air inlet smoke box through stay segment.
The utility model reactor for production of carbon black all adopts refractory metal material to make burner hearth.Contour dimension is little, and is in light weight, long service life, and maintenance cost is low, heat energy utilization rate height, does not produce the logistics of burner hearth material scaling loss and goes into to influence in the carbon black smoke quality in the charcoal, carbon black mass height, can guarantee production line operation ratio height.
