Study of Air Purification Device Layout in Coal Mine Refuge Chamber
HE Tingmei
Abstract：In this PaPer,a calculation exPression for the harmful gas concentration in the refuge chamber was deduced according to the law of conservation of matter,and the mathematical relationshiP of the required air quantity for Purification in the refuge chamber with the control of the harmful gas concentration and number of the Persons stayed in the chamber was established. With Fluent software,analysis was made on the distribution of the air flow rate and CO2 concentration in the refuge chamber under three different oPeration conditions of 51-tyPe chamber Purification device. It came to a conclusion that using two air Purification devices could control CO2 volume fraction below 0. 50% and meet the air Purification requirement in the refuge chamber.
