Description
Technical Field
The utility model relates to the technical field, in particular to a large-particle-size blue-phase carbon black and conductive carbon black reactor.
Background
Carbon black is generally classified into two main groups, carbon black for rubber and special carbon black. The carbon black for rubber is mainly applied to tires, mainly plays roles of reinforcing and filling, and the yield of the carbon black accounts for about 90 percent. The special carbon black has the functions of coloring, aging resistance, ultraviolet resistance and conductivity, such as pigment carbon black, conductive carbon black and the like, and the yield of the special carbon black accounts for about 10 percent of the carbon black. The large-particle-size blue-phase carbon black and the conductive carbon black related to the patent belong to special carbon black.
The large-particle-size blue-phase carbon black is applied to color mixing in the fields of ink and paint, and the conductive carbon black is applied to the fields of cable rubber protection layers, antistatic rubber conveyor belts, new energy batteries and the like.
Carbon black is a chemical product produced by taking fossil energy or a processed product thereof as a raw material, such as natural gas, coal tar produced by coal coking, ethylene tar produced by naphtha refining, heavy oil and the like. The prior art process flow for producing carbon black is shown in figure 1. The technological process in the prior art comprises the following steps: the fuel oil or fuel gas is injected into the carbon black reactor after being pressurized, and is mixed with air supplied by a main air supply fan and preheated by an air preheater in a combustion section of the reactor to be completely combusted, so as to generate high-temperature combustion air flow at 1900 ℃. The raw oil stored in the raw oil tank is pumped to an on-line raw oil preheater, preheated to the temperature of more than 250 ℃ for example, radially sprayed into a throat section of the reactor, mixed with high-temperature combustion air flow, and rapidly cracked to generate carbon black.
In the cooling section of the reactor, water is directly sprayed into the high-temperature carbon black smoke to quickly reduce the temperature of the carbon black smoke and terminate the reaction. The flue gas subjected to quenching termination carbon black reaction sequentially passes through a high-temperature air preheater, an online boiler and a raw oil preheater, is further cooled and recycled, and then enters a main bag filter to separate carbon black from the flue gas. The collected carbon black is transported by hot air, passes through a grinder and is sent to a collecting bag filter by an air blower. The air coming out of the collecting bag filter is directly discharged; the collected carbon black is subjected to granulation, lifting, magnetic separation, storage, packaging and warehousing.
The tail gas exhausted from the main bag filter is pressurized by a fan and then is sent to a boiler of the steam-electricity cogeneration device to be used as fuel, and steam and electric power are generated to be returned for the carbon black device to be used for production and living or to be supplied outside the internet. And the flue gas discharged by the boiler is treated by a desulfurization and denitrification device to reach the standard and then is discharged.
Carbon black dust possibly leaked into the environment in the production process is pumped by a dust suction fan to be sent to a recovery bag filter, carbon black is recovered, and air is exhausted.
Carbon black production the foremost is a carbon black reactor, in addition to the feedstock. The reactor in the prior art consists of five sections, namely a combustion section, a throat section, a reaction section, a cooling section and a residence section. The fuel and combustion air enter the combustion section at the same time, high-temperature flue gas is generated by complete combustion in the combustion section and flows through the throat section, raw oil is radially sprayed into the high-temperature air flow from the throat section and enters the reaction section, the carbon black is generated by endothermic thermal cracking reaction in the reaction section, the carbon black-containing flue gas flows through the cooling section and is radially sprayed into the quenching water cooling termination reaction, and the carbon black flue gas discharged from the reactor enters the rear waste heat recovery system, the carbon black flue gas separation system, the carbon black granulation packaging system and the flue gas waste heat recovery system. When the existing carbon black reactor is used for producing conductive carbon black, the quenching water spraying position is close to the reaction section, namely a short quenching position, and the reaction time is very short; when producing large-particle-size blue-phase carbon black, the cooling water spraying position is close to the tail part of the reactor, namely the long quenching position, and the reaction time is long.
The structure of the existing reactor consists of steel furnace shells and refractory materials in sections. The furnace shell is usually carbon steel, and high-temperature paint with the temperature of more than 300 ℃ is sprayed after sand blasting and rust removal. The refractory material is usually two or three layers, the inner layer and the high-temperature airflow contact layer adopt refractory brick products matched with the using temperature, the outer layer is an insulating layer, and the insulating brick products matched with the using temperature are used for masonry.
Problems with existing reactors:
1. the high-temperature section, particularly the combustion section, the throat section and the reaction section of the existing reactor are easy to burn out the furnace body by channeling fire. The fire-resistant layer and the heat-insulating layer of the furnace body structure are prefabricated forming bricks, so that the brick joints are difficult to ensure uniform and consistent in size during building, and the heat-expansion and cold-contraction occur when the furnace body structure is started and stopped at a high temperature for a certain time, so that the brick joints are enlarged due to larger shrinkage deformation of the heat-insulating bricks, and fire channeling is easy to occur.
2. The product quality is unstable. The reason is that the raw oil is sprayed in the radial direction of the throat section, and the nozzle is easy to deform and even burn when exposed to a high-temperature airflow environment, so that the uniform spraying and atomization of the raw oil are damaged, and the product quality is unstable.
3. The raw oil is atomized mechanically by pressure, and is easily coked under the influence of the temperature and pressure of the raw oil, the aperture of a nozzle and the injection angle, and the quality of products is influenced by the generation of screen residues. The reason is that in addition to item 2 above, radial injection of the feed oil may cause excessive penetration to inject the feed oil onto the furnace walls, causing coking.
4. The refractory material of the throat section is easy to fall off and deform. The reason is that the raw oil is unevenly sprayed at the throat section and scour caused by the maximum flow velocity at the throat section. The falling of the refractory material not only can increase ash content of a carbon black product, but also can cause disqualification of the product due to continuous increase and irregularity of the diameter of the throat section, and the fluid working condition deviates from the design working condition along with the length of the service time, so that the physicochemical index of the product is seriously influenced.
