Description

Technical Field

[0001] The utility model relates to the technical field of tail gas waste heat recovery device structures, in particular to a tail gas waste heat recovery device for titanium micropowder production. Background Art

[0002] Titanium micropowder is a fine powder made of titanium element, which usually has the characteristics of fine particles and large specific surface area. Titanium micropowder can be prepared by a variety of methods, such as sulfuric acid method, atomization method, mechanical method, etc. These different preparation methods will affect the particle size, purity, morphology and other properties of titanium micropowder. Titanium micropowder has a wide range of applications in industry, such as as a vacuum coating titanium agent, titanium iron casting additive, etc. Due to its unique physical and chemical properties, titanium micropowder can also be used to manufacture high-performance ceramics, coatings, composite materials, etc. In addition, titanium micropowder can also be used in scientific research, such as as a catalyst, sensor material, etc. Titanium micropowder will produce high-temperature exhaust gas during the production process.
