Embodiment Construction

[0007] The specific embodiment of the present invention will be described in detail below in conjunction with the process flow diagram.

[0008] Depend on figure 1 Shown, the present invention is realized by the following methods in concrete implementation:

[0009] Low-concentration gas refers to by volume: methane 3%-25%, oxygen 11%-15%, nitrogen 54%-72%, carbon dioxide 0.1%-4%, combustible impurity gas 0-2%, non-combustible impurity gas 4%-7%, the total content is 100%, relative humidity ≥ 70%, temperature ≤ 57 ℃ gas, the gas is sent from the pumping pump station (pump station outlet pressure 30KPa-50KPa) into the water submerged relief valve 1. Adjust the pressure, and then send it to the first water-sealed flame arrester 2 to filter the large particles of solid impurities in the gas, and keep the pressure of the gas below 30KPa to eliminate the flame and ensure safety, and then enter the second A pipeline gas cooling displacer 3, the first pipeline gas cooling displacer...

Abstract

The invention relates to a low-concentration gas power generation treatment method, which can effectively realize the effects of preventing environment pollution and saving energy sources when low-concentration gas is utilized for power generation. The method is characterized in that firstly, the low-concentration gas is conveyed into a water settling type bleeding valve by a pumping pump stationfor pressure regulation, then, large-particle impurities of the gas are filtered by a first water sealing type bleeding flame arrestor, next, the gas enters a pipeline gas cooling displacer for carbon dioxide removal and enters a water settling type waterproof valve, dissociative liquid in the gas is removed, next, the gas enters the gas pipeline gas cooling displacer for further carbon dioxide removal and dissociative liquid removal, the gas is subjected to water sealing isolation by the water sealing type bleeding flame arrestor and passes through a condensing dehydration system, the impurities in the gas are subjected to temperature reduction and cooling, the dehydration is carried out, and finally, the gas enters a cylinder through a dry type flame arrestor and an explosion-proof electromagnetic valve to be combusted for work application and power generation. The treatment method has the advantages that safety and reliability are realized, the treated gas can be effectively utilized for power generation, and the environment pollution is reduced.

Description

technical field [0001] The invention relates to gas, in particular to a treatment method for generating electricity from low-concentration gas. Background technique [0002] The gas reserves are huge, and my country alone has 36 trillion cubic meters of reserves. The annual gas extraction volume of major coal mines exceeds 10 billion cubic meters. However, due to technical limitations, geological conditions and other factors, the current concentration in coal mine drainage is less than 10%. The total discharge of low-concentration gas accounts for a large proportion, exceeding 60%-70%. Low-concentration gas with a volume concentration of methane of 3%-8% is difficult to utilize, and the utilization ratio is extremely low. At present, all mines still use direct It is mainly discharged into the atmosphere. On the one hand, this treatment method is a waste of a large amount of valuable resources, and on the other hand, it greatly damages the composition of the ecological environm...
