Description

Technical Field

[0001] The invention belongs to the technical field of preparing nano powder materials by adopting an atomizing flame synthesis method, and in particular relates to an atomizing synthesis burner group which is convenient for integrated manufacturing. Background Art

[0002] Atomized flame synthesis technology has many advantages in the preparation of nanopowder materials, especially high-end nanopowder materials. The commonly used atomized flame synthesis burners currently use a combustion organization method in which the atomized precursor is arranged in the center of the burner and a high-temperature swirl flame is constructed around the atomized airflow. Powder materials with good performance can be prepared at a smaller atomized precursor flow rate, but when the atomized precursor flow rate is increased, the atomized flame performance will change due to reasons such as the increase in atomized jet momentum, affecting the performance of the synthesized powder material. In this case, in order to increase the synthesis output of powder materials, it is often necessary to use multiple independently designed and processed atomized flame synthesis burners for simultaneous synthesis. The process of directly arranging multiple such burners in parallel is likely to cause the overall process to be complicated, the difficulty of regulation to increase, and the cost to increase.

[0003] In order to solve the above problems, the present invention proposes an atomizing synthesis burner group which is easy to manufacture and integrate, and has the advantages of being easy to manufacture, having low processing cost and being easy to control. Summary of the invention
