Technical Field
The utility model relates to a carbon black production technical field specifically is a water jacket formula metal choke for production carbon black.
Background
At present, the domestic wet granulation carbon black reaction furnace structure generally comprises three parts of a combustion chamber (also called a combustion section), a hydrocarbon spraying chamber (also called a throat section because the combustion chamber closely resembles the throat of a person), a reaction chamber (also called a reaction section) and the like, wherein one end of the combustion chamber is provided with a fuel oil spraying inlet, the other end of the combustion chamber is connected with a throat pipe, a raw oil spraying inlet is radially arranged on the throat pipe, and the other end of the throat pipe is connected with the reaction chamber. Usually, the throat section is formed by pouring chrome corundum castable or building zirconium chrome corundum bricks. The temperature of the gas in the throat section can reach 1900 ℃, the flow rate can reach more than 500m/s, and the oil drops which are not before gasification after the raw materials are sprayed into the throat section have a scouring effect on the throat. Under the action of the factors, a section of the throat castable facing the reaction section is slowly flushed away by airflow with the lapse of time, and after the throat castable is generally used for 3 months, the diameter of the throat is slowly increased and irregular, so that the airflow velocity in the throat is gradually reduced, and the inherent quality of carbon black is gradually reduced. Therefore, the method of frequently replacing the throat pipe has to be adopted in production, however, due to the property limitation of the refractory materials, a method of gradually raising the temperature is required after the furnace is replaced with a new furnace to ensure that the dehydration, the phase change and the like of the furnace materials are normally carried out, and the work wastes a large amount of time and consumes a large amount of fuel.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a water jacket formula metal choke for production carbon black to solve the problem that proposes in the above-mentioned background art.
