Embodiment 1

[0032] The preparation method of gas eliminator, the steps are as follows:

[0033] (1) The bean seedlings are fermented in a closed manner under normal temperature and pressure for 10 days, and the fermentation gas I and the fermentation liquid I are collected; the bean seedlings are mature seedlings of soybeans, black beans, mung beans or crotons with a humidity of 60%.

[0034] (2) Take surface soil samples from a 10-year waste landfill (the landfill complies with the "Landfill Pollution Control Standard for Domestic Waste" GB16889-2008), add 10 times the volume of water, and fill it at 28°C Fermentation gas I, after 50 days of cultivation, the fermentation liquid II formed is collected; the addition ratio of the surface soil sample taken from the landfill to the fermentation gas I is 1:100.

[0035] (3) Add fermentation liquid I to fermentation liquid II, then add fresh crop straw, transfer to a closed fermentation tank, and ferment under vacuum for 10 days to obtain fermentation...

Embodiment 2

[0038] The preparation method of gas eliminator, the steps are as follows:

[0039] (1) The bean seedlings are fermented in a closed manner under normal temperature and pressure for 20 days, and the fermentation gas I and the fermentation liquid I are collected; the bean seedlings are mature seedlings of soybeans, black beans, mung beans or crotons with a humidity of 70%.

[0040] (2) Take surface soil samples at a 5-year waste landfill site (the landfill meets the "Landfill Pollution Control Standard for Domestic Waste" GB16889-2008), add 10 times the volume of water, and fill it at 30°C Fermentation gas I, after 70 days of cultivation, the fermentation liquid II formed is collected; the addition ratio of the surface soil sample taken from the landfill to the fermentation gas I is 1:1000.

[0041] (3) Add fermentation liquid I to fermentation liquid II, then add fresh crop straw, transfer to a closed fermentation tank, and ferment for 20 days under vacuum conditions to obtain fermen...

Embodiment 3

[0044] The preparation method of gas eliminator, the steps are as follows:

[0045] (1) The bean seedlings are fermented in a closed manner under normal temperature and pressure for 15 days, and the fermentation gas I and the fermentation liquid I are collected; the bean seedlings are mature seedlings of soybeans, black beans, mung beans or crotons with a humidity of 65%.

[0046] (2) Take surface soil samples at the 12-year waste landfill (the landfill meets the "Landfill Pollution Control Standard for Domestic Waste" GB16889-2008), add 50 times the volume of water, and fill it at 29°C Fermentation gas I, after 60 days of cultivation, the fermentation liquid II formed is collected; the addition ratio of the surface soil sample taken from the landfill to the fermentation gas I is 1:500.

[0047] (3) Add fermentation liquid I to fermentation liquid II, then add fresh crop straw, transfer to a closed fermentation tank, and ferment under vacuum for 15 days to obtain fermentation liquid ...

Abstract

The invention relates to the technical field of gas control, in particular to a preparation method of a gas elimination agent and application thereof. The preparation method of the gas elimination agent comprises the following steps that bean seedling is sealed and fermented, fermentation gas I and fermentation liquid I are obtained; water and the fermentation gas I are added to the surface of a refuse landfill; fermentation liquid II is collected after fermentation; the fermentation liquid I and crop straw are added into the fermentation liquid II; fermentation liquid III is collected; and the gas elimination agent is obtained after dilution. Ten days after the gas elimination agent is injected into a mine, gas is reduced by 54.42%, after eleven days, the gas content is reduced by 79.59%,and after twenty-two days, the gas is reduced by 82.39%. Compared with an existing method of eliminating methane by a chemical method, secondary pollution is avoided, the method is safe and mild, crop waste is adopted, and the problem that the crop waste is hard to process is solved. The gas is cleared more completely, and production efficiency is increased multiply.

Description

Technical field [0001] The invention relates to the field of gas treatment, in particular to a preparation method and application of a gas eliminator. Background technique [0002] The governance of gas is a worldwide problem, and there is no fundamental solution to the gas disaster. Therefore, in many developed countries, in order to reduce the occurrence of accidents, it is forbidden to mine mines with a large amount of gas emission and only mine mines with a small amount of gas emission. my country is a developing country, and energy is very scarce. Coal accounts for more than 70% of my country's total energy consumption. The output of coal directly affects the development of the national economy (Zhu Wangxi et al., 2004). As a result, as long as there are coal reserves in our country, whether it is low gas or high gas mining areas, they are actively creating conditions for mining. However, the number of mines in our country and their distribution ranks first in the world. ...
