Unmanned automatic gas extraction system

Abstract

The invention discloses an unmanned automatic gas extraction system. A multi-pipeline acquisition module mounting area is divided into a plurality of groups, and each group comprises a plurality of gas extraction pipelines which are adjacently arranged; an extraction pipe of each gas extraction pipeline extends into a gas extraction drill hole of a coal bed; each gas extraction pipeline in each group is connected in parallel to a corresponding multi-way connecting disc; the multi-way connecting discs in each group are connected to an extraction negative pressure main pipe through the extraction negative pressure branch pipes arranged in parallel. Through the design of the multi-pipeline collection module, distributed collection can be carried out on the interior of a mining area, independent grouping control can be carried out, the extraction efficiency is improved, and energy is reduced; due to the design of a gas filtering module, impurities in extracted gas can be filtered and removed, and the purity degree of the gas content is guaranteed; a gas leakage monitoring module and an alarm module are used in cooperation, monitoring can be conducted in the gas collection process, serious safety accidents caused by the fact that leakage is not known by people are avoided, and the safety in the working process is improved.

Description

technical field

[0001] The invention relates to the technical field of gas collection, in particular to an unmanned automatic gas extraction system. Background technique

[0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In a high temperature and high pressure environment, while coal is formed, gas continues to be generated due to physical and chemical effects. It is a colorless, odorless gas, but sometimes you can smell an apple-like aroma. This is due to the simultaneous gushing of aromatic hydrocarbon gas and gas. The relative density of gas to air is 0.554. The density is 0.716kg / m3, and the permeability of gas is 1.6 times that of air. It is difficult to dissolve in water, does not support combustion and cannot maintain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can burn or explode. Gas exists i...
