Gas generator set with flow and concentration fluctuation self-adjusting and adjusting method

Abstract

The invention relates to a gas generator set with flow and concentration fluctuation self-adjusting and an adjusting method. The gas generator set with the flow and concentration fluctuation self-adjusting comprises a gas storage tank, a CNG storage tank, a LNG storage tank, a buffering tank, a gas fine mixing tank, a gas coarse mixing tank, a controller, a gasifier, a compressor, a sensor, an electric control valve, a gas pipeline, the gas generator set and the like. The problem that the coal-mine gas flow and concentration fluctuation are large is solved, gas with various concentration extracted by a coal mine is used for stably generating electricity, when the coal-mine gas concentration and flow cannot support the gas generator set for full load electricity generating, stored abundantgas and outsourcing CNG and LNG are used as gas supply, the gas flow and concentration are automatically adjusted, evacuation of the gas with the concentration less than 8% is fully used, and resourcewaste and environment damage are avoided; and meanwhile, a gas generator is used as a spare electricity source, overlapping investment is avoided, the coal mine electricity utilization safety guarantee intensity is improved, and larger economic value and practical value are achieved.

Description

technical field [0001] The invention relates to a gas generator set and an adjustment method for automatic adjustment of flow and concentration fluctuations, and belongs to the field of gas utilization equipment. Background technique [0002] Coal mine gas is a hydrocarbon gas that exists in coal seams and coal-measure formations. It is not only a high-quality clean energy, but also a greenhouse gas. In 2016, the national coal mine drainage volume was 17.3 billion cubic meters, the utilization volume was 9 billion cubic meters, and the utilization rate was only 52%. Under the existing technical conditions, according to the gas concentration, there are mainly several ways to use it: high-concentration gas with a concentration ≥ 30% can be directly used as chemical raw materials and gas-fired power generation; low-concentration gas with a concentration of 8-30% can be used for internal combustion power generation. More than 60% of the gas is low-concentration gas; for ultra-l...
