Description

technical field [0001] The invention relates to the technical field of furnace carbon black, in particular to a production device and a use method of a novel furnace carbon black. Background technique [0002] Furnace carbon black is to use gaseous hydrocarbons, liquid hydrocarbons or their mixtures as raw materials, supply an appropriate amount of air, and form a closed turbulent system in the reaction furnace, burn a part of the raw material hydrocarbons and air to generate high temperature, and crack the other part to produce carbon. black. Carbon black is a black powdery substance formed by incomplete gas phase combustion or pyrolysis of hydrocarbons under strictly controlled process conditions. Its main component is elemental carbon and contains a small amount of oxygen, hydrogen, sulfur, etc. Carbon black particles are approximately spherical, with a particle size of 10-500 μm. Carbon black products are used in rubber processing and added to rubber as reinforcing age...

Problems solved by technology

[0003] However, although the existing production method can produce furnace carbon black, there are still many defects: 1, the production line of the existing furnace carbon black is long, and the operation of the equipment needs more labor to realize, and in When atomizing, the production line directly uses the combination of air pump and pump head to atomize. Although this type of atomization has high efficiency, the effect is not good due to the rapid injection of crude oil or secondary fuel, and the current atomization effect is It is not directly related to the power of the atomizing pump. Even if the suction force of the pump is increased, there will still be excess large particles of crude oil dripping, thereby reducing the efficiency of particle formation

2. At present, the crude oil in the production line is mainly pumped out through pumps. The output of crude oil is relatively large, and it is difficult to control the actual needs of crude oil. Moreover, the existing technology mainly directly mixes crude oil, secondary fuel and air, and the mixed not effectively

3. The existing turbulent flow system is mainly set inside the cavity, and the turbulent flow is realized by changing the diameters of the end and the tail. However, due to the influence of the flow velocity near the side wall in the turbulent flow system, it can be close to the inner wall. Poor flow rate of crude oil or secondary fuel, which affects the efficiency of agglomeration

4. The current cooling system only cools the end of the turbulent system, but the cooling effect is not good due to the large flow rate and flow in the turbulent system, so there is an urgent need for a new type of furnace carbon black. Production device and method of use
