Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas purification, and in particular relates to an exhaust gas purification treatment device. Background Art

[0002] Sintering and curing is an important process link of magnetic materials in powder metallurgy technology. After the metal magnetic powder particles are stirred and mixed with the binder to form a mixture, a certain pressure is applied to form a molded blank. The molded blank needs to be metallurgically bonded at high temperature to connect the powder particles together so that it has a certain strength. This process is called sintering and curing. Degreasing is to remove a certain amount of binder in the blank during the sintering and curing process. The degreasing process generally puts the molded blank into a sintering heat treatment furnace, heats the heat treatment furnace first, and continuously passes the preheated inert gas (usually nitrogen and argon) into the furnace to exhaust the air in the furnace. Generally, the binder is an organic matter, which decomposes under high-temperature inert gas, and produces some harmful solid particles and is discharged from the furnace along with the exhaust gas. If the exhaust gas is not treated and directly discharged into the air, the solid particles will cause great harm to the environment. Utility Model Content
