Description

Technical Field

[0001] The present invention belongs to the technical field of acetylene carbon black production, and particularly relates to a production process for reducing impurities in acetylene carbon black. Background Technique

[0002] Acetylene carbon black, also known as acetylene black or ACET, is a high-purity carbon black material, mainly obtained by pyrolyzing acetylene with a purity of over 99% obtained by decomposing and refining the by-product gas during the calcium carbide method or the pyrolysis of naphtha (crude gasoline), and then through continuous pyrolysis. It appears as an extremely fine black powder, having excellent electrical conductivity, thermal conductivity and antistatic effect, and an extremely low resistivity. The purity of acetylene carbon black is very high, with a carbon content greater than 99.5%, a hydrogen content less than 0.1%, and an oxygen content between 0.07% and 0.26%. Due to its excellent electrical conductivity and liquid absorption, acetylene carbon black has a wide range of applications in the fields of battery manufacturing, electronic components, conductive rubber, conductors, cable shielding materials, etc. In the manufacturing of batteries such as dry batteries, lead-acid batteries, and lithium batteries, acetylene carbon black, as a conductive material, can significantly improve the electrical conductivity and storage performance of the batteries. In addition, acetylene carbon black is also commonly used in products such as conductive and antistatic rubber, silica gel and plastics, cable shielding materials, as well as in the fields of electromagnetic wave insulation and gas dispersion electrodes, catalyst materials, microwave absorption materials, etc.

[0003] In order to reduce the impurity content in acetylene carbon black, manufacturers usually adopt precise raw material screening and purification processes to ensure that the acetylene gas used has high purity. During the production process, the reaction conditions and operating parameters, such as temperature, pressure and reaction time, are strictly controlled to minimize the generation of by-products. In addition, efficient separation and purification technologies are adopted, but when the existing acetylene carbon black preparation devices are in use, the raw materials inside the stirring tank are usually stirred by the stirring blades on a single stirring shaft, and the raw materials near the inner wall position are difficult to be stirred and mixed fully and efficiently, affecting the efficiency of uniform stirring and mixing of the raw materials. At the same time, when discharging, the viscosity of the material becomes larger and the discharge port is easily blocked.

[0004] Therefore, a production process for reducing impurities in acetylene carbon black is needed to solve the problems raised in the above background technique. Summary of the Invention

Then, the acetylene black raw material and the reaction raw material inside the reactor 6 are fully stirred in a multi - point manner through the stirring rod a502 and the stirring rod b504, so that the materials are evenly mixed, which can significantly improve the reaction efficiency and uniformity. This method ensures that the raw materials are evenly mixed in every corner of the reactor. S2. Convey the gas into the ventilation cavity 103 through the intake air pipe 101, and blow the gas evenly and finely into the materials inside the reactor 6 through the plurality of blowing holes 102, improving the activity degree of the materials.
