AI Technical Summary
Existing monorail crane exhaust gas treatment devices cannot effectively treat CO in confined underground spaces, especially when the monorail crane is not in operation, they cannot reduce the CO concentration in the air. Furthermore, existing devices suffer from problems such as easy saturation of the adsorbent and environmental pollution during regeneration.
A CO catalytic device for exhaust gas from a monorail crane in an underground coal mine was designed. The device employs a honeycomb ceramic carrier and a catalyst coating for two-stage catalytic treatment of the exhaust gas. When the monorail crane is not in operation, air is drawn in by a drive motor for catalytic treatment. Air pressure and heating bars are used to improve the contact efficiency between air and the catalyst.
It achieves efficient catalytic treatment of exhaust gas during the operation of underground monorail cranes, reduces CO concentration in exhaust gas and air, improves treatment efficiency, ensures underground safety, and has a simple structure and low cost, making it suitable for confined underground spaces.
