The invention discloses a
coal mine gas comprehensive application
system and an application method thereof. The
system comprises a
coal mine ventilation air measuring component, a
coal mine gas measuring component, a high-concentration gas treatment subsystem, a low-concentration gas treatment subsystem, a coal mine ventilation
air treatment subsystem and an afterheat treatment subsystem, wherein a high-concentration gas pre-treatment device and a high-concentration
gas generator set are connected via a pipeline to form the high-concentration gas treatment subsystem, a safe conveying device, a low-concentration gas pre-treatment device and a low-concentration
gas generator set are connected via pipelines to form the low-concentration gas treatment subsystem, the high-concentration
gas generator set and the low-concentration gas generator set are respectively connected with a
power grid via cables, a ventilation air delivering connecting device, a mixing device and a ventilation air oxidization device are connected via pipelines to form the coal mine ventilation
air treatment subsystem, and the afterheat treatment subsystem is respectively connected with the high-concentration gas treatment subsystem, the low-concentration gas treatment subsystem and the coal mine ventilation
air treatment subsystem. The coal mine gas comprehensive application
system and the application method can be used for comprehensively applying gas with different concentrations,
utilization rate of the gas is the highest, emission of
greenhouse gas is reduced, and comprehensive recycling of energy is realized.
