A material spray lance is arranged on the upper part of the utility model, the utility model is provided with a tuyere cooler, a reaction section is arranged on the lower part of the tuyere cooler, an activation flue is arranged on the lower part of the reaction section, a mutation cross-section is not arranged on the reaction section, and a spray inlet is arranged in the middle part of the reaction section. The utility model has the advantages of simple structure and convenient operation, the condition that the reaction stove is in a flow state of smooth piston flow in a reaction process is used, the occurrence of the phenomenon of 'back mixing ' can be reduced, low reaction temperature of soft carbon black can be avoided, the occurrence of easy coking phenomenon can be avoided, and guarantee is provided to produce carbon black of good quality.
Description
The utility model relates to a kind of soft carbon production equipment.
The generation of soft carbon generally is to make fuel with gaseous state or liquid hydrocarbon, perfect combustion generation high-temperature fuel gas spreads and delivers to conversion zone in the combustion chamber, hydrocarbon feed is sprayed in the high-temperature fuel gas stream, raw material hydrocarbon incomplete combustion and generate carbon black, the high temperature carbon black suspension air-flow quick cooling that obtains like this and make the reaction stop, carbon black smoke passes through capturing devices such as cyclonic separator, bag filter again, carries out carbon black to reclaim, and this powdery carbon black passes through common granulation, drying treatment as the carbon black finished product.
The production of soft carbon except that giving the different reinforcing property of rubber item, is more having its uniqueness than hard (carbon) black aspect production method and the formation condition, comparatively speaking, the temperature of reaction that soft carbon generates is lower, and the reaction times is longer, generates the carbon black grain through bigger.The production equipment of soft carbon is constantly improving at present, each production firm mainly is the characteristics that propose on Reaktionsofen structure and production technique separately, but the raw material and the fuel hydrocarbon that all are based in the production separate, raw material hydrocarbon is sprayed in the high temperature gas flow that fuel hydrocarbon provides, this technology of generation carbon black proposes different Reaktionsofen structures, though this Reaktionsofen structure and production have advantages such as can improving the sooty production rate, but difficulty relatively on technology controlling and process particularly is easy to generate hard (carbon) black in reaction process and causes the impurity level in the carbon black products to increase.This is that rubber grade carbon black institute is unallowed, and foreign matter content is too high, will the performance of rubber item be reduced.React insufficient also influential simultaneously to the carbon black performance index.
The purpose of this utility model provides a kind of cylindrical structure Reaktionsofen, soft carbon in reaction process with plug flow flow state stably, reduced the generation of " back mixing " phenomenon, avoided the soft carbon temperature of reaction low, the easily generation of coking phenomenon provides the soft carbon production equipment that guarantees for producing high-quality carbon black.
The utility model is to adopt such method to realize: the soft carbon production equipment is the Reaktionsofen that adopts cylinder type, on Reaktionsofen, has a tuyere cooler, on its tuyere cooler, has a stock oil spray gun, has conversion zone in the tuyere cooler bottom, have the activation flue in the conversion zone bottom, have entrance at the middle part of conversion zone.In whole body of heater without any abrupt-change cross section, use this Reaktionsofen just, soft carbon in reaction process with plug flow flow state stably, reduced the generation of " back mixing " phenomenon, avoided the soft carbon temperature of reaction low, the easily generation of coking phenomenon provides assurance for producing high-quality carbon black.
For the optimum reacting time of determining soft carbon and the temperature in Reaktionsofen, flow rate state.According to the production different varieties with use the raw material oil condition, the reaction times is 0.8-1.5 second, and temperature of reaction is 1150-1250 ℃.
Will there be enough soak times in the soft carbon formation reaction later stage, so body of heater will have the activation flue, to improve the surface property of soft carbon.
On cylindric big reaction unit, has a supply mode for axially supplying with, the stock oil nozzle of a big atomizing angle is provided, the stock oil of big thus atomizing angle nozzle ejection at a certain angle and the high temperature air that gives after the heat mix, clash into mutually with the high speed airflow at the place, air port and carry out entering Reaktionsofen behind the secondary-atomizing.The atomizing angle of oil burner nozzle is greater than 90 °, and place, air port high temperature air flow velocity is the 180-240 meter per second.Axially can produce the soft carbon kind of particle size distribution broad, satisfy rubber item reinforcing property and elastic particular requirement for the mode of stock oil.
The utility model compared with prior art, have simple in structure, easy to operate, as to be easy to control characteristics, and the soft carbon production equipment is a Reaktionsofen of adopting cylinder type, in whole body of heater without any abrupt-change cross section, use just this Reaktionsofen in reaction process with plug flow flow state stably, reduced the generation of " back mixing " phenomenon, avoided the soft carbon temperature of reaction low, the easily generation of coking phenomenon provides assurance for producing high-quality carbon black.Satisfy rubber item to reinforcing property and elastic particular requirement.
Concrete structure of the present utility model and embodiment are provided by the following drawings,
What accompanying drawing provided is overall cross-sectional view of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.
See shown in the accompanying drawing: apparatus for producing soft carbon black is the reacting furnace of adopting cylinder type, at reacting furnace On have a tuyere cooler 2, have a feedstock oil spray gun 1 at its tuyere cooler 2, at air port water Overlap 2 bottoms and have conversion zone 3, have activation flue 4 in conversion zone 3 bottoms, at the middle part of conversion zone 3 tool Entrance 5 is arranged. In whole body of heater, without any abrupt-change cross section, use just the soft charcoal of this reacting furnace Deceive in course of reaction with plunger stream flow regime stably, feedstock oil through oily spray gun 1 with bigger atomizing The angle sprays into from tuyere cooler 2, clashes into by secondary-atomizing mutually laggard with the high-speed air at tuyere cooler 2 places Enter reacting furnace, at high temperature a part of feedstock oil burning provides heat, and a part of cracking reaction generates charcoal Black. After in reacting furnace, finishing the carbon black reaction, sprayed into from chilled water (chw) entrance 5 in the reacting furnace end Cooling stops reaction, enters then activation flue 4, and last carbon black smoke enters posterior means to be continued by cold But, separation and collection.
Oily spray gun 1 atomizing angle on the reacting furnace device 〉=90 °, tuyere cooler 2 diameters are 120mm, reaction Section 3 diameter 700mm, length is 15 meters, and activation flue 4 diameters are 600mm, and length is 9 meters.
