Embodiment 1

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

[0033] (1) The bean seedlings are fermented under normal temperature and pressure conditions for 10 days in a closed manner, 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, and the humidity is 60%.

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

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

Embodiment 2

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

[0039] (1) The bean seedlings are fermented under normal temperature and pressure conditions for 20 days in a closed manner, 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, and the humidity is 70%.

[0040] (2) Take surface soil samples from the 5-year-old landfill site (the landfill site complies with the "Standards for Pollution Control of Domestic Waste Landfill" GB16889-2008), add 10 times the volume of water, and fill it at 30°C Fermentation gas I was cultured for 70 days, and the fermented liquid II formed was collected; the ratio of topsoil samples taken from the landfill to fermentation gas I was 1:1000.

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

Embodiment 3

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

[0045] (1) The bean seedlings are fermented under normal temperature and pressure conditions for 15 days in a closed manner, 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, and the humidity is 65%.

[0046] (2) Take surface soil samples from the landfill site in 2012 (the landfill site complies with the "Standards for Pollution Control of Domestic Waste Landfill" GB16889-2008), add 50 times the volume of water, and fill it at 29°C Fermentation gas I was cultured for 60 days, and the fermented liquid II formed was collected; the ratio of surface soil samples taken from the landfill to fermentation gas I was 1:500.

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

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 control, in particular to a preparation method and application of a gas eliminating agent. Background technique [0002] Gas management is a worldwide problem, and there is no fundamental solution to gas disasters. Therefore, in order to reduce the occurrence of accidents, many developed countries prohibit the mining of 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, and coal production directly affects the development of the national economy (Zhu Wangxi et al., 2004). This has led to actively creating conditions for mining wherever there are coal reserves in our country, no matter whether it is a low-gas or high-gas mining area. And the number of mines in my country ranks first in the world in the widest distribution. All...
