Coal mine gas comprehensive application system and application method thereof

Abstract

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.

Description

technical field [0001] The invention relates to an environment-friendly and recyclable energy device and its application method, in particular to a coal mine gas comprehensive application system and its utilization method. Background technique [0002] Coal mine gas, commonly known as coalbed methane, belongs to unconventional natural gas and is a high-quality energy and chemical raw material. [0003] China is not only a country with rich coal resources, but also extremely rich coal-bed methane resources. The Chinese government and relevant industrial departments pay close attention to the exploration and development of coalbed methane, and have achieved remarkable results this year. However, due to various reasons, the ratio of investment and return is still not satisfactory. First of all, China's geological conditions are complex, and the geological theory of coal mine gas is not yet mature. There is a lack of systematic discussion and summary of the coal seam gas conte...

Problems solved by technology

[0006] 2. Low-concentration gas with a concentration greater than 5% and less than 30%, according to recent national regulations, can only be used under the premise of installing a safe delivery system

Since this part of the gas cannot be used directly, it is basically emptied directly, which wastes available resources.
