Exhaust gas treatment device and powder treatment system

The invention provides an exhaust gas treatment device and a powder and granular material treatment system capable of suppressing environmental deterioration caused by exhaust gas from the powder and granular material treatment device. And the shell (6) of the exhaust treatment device (3) is arranged outside the powder treatment device (2). A housing (6) of the exhaust gas treatment device (3) is provided with an intake port and an exhaust port. Exhaust gas from the powder processing device (2) is taken into the housing (6) from the intake port, is decomposed, and then is discharged to the outside of the housing (6) through the discharge port (94). 本发明提供一种能够抑制来自粉粒体处理装置的排气所导致的环境恶化的排气处理装置及粉粒体处理系统。排气处理装置(3)的壳体(6)设置在粉粒体处理装置(2)的外部。在排气处理装置(3)的壳体(6)中设置有取入口及排出口。来自粉粒体处理装置(2)的排气从取入口被取入到壳体(6)内，经过分解处理后，通过排出口(94)排出到壳体(6)外。
