Abstract
The invention discloses a kind of collecting methods of coal bed gas, include the following steps：Step（1）：By the coal bed gas extracted in coal bed gas well by the drier equipped with drier, being dried coal bed gas except water process；Step（2）：It will be through step（1）The coal bed gas obtained after processing is passed through in primary filter, and preliminary filtration treatment is carried out to coal bed gas；Step（3）：It will be through step（2）The coal bed gas obtained after processing is passed through in high efficiency particulate air filter, and smart filtration treatment is carried out to coal bed gas；Step（4）：By step（3）The coal bed gas obtained after processing is imported in storage tank and is stored.The present invention can carry out coal bed gas after extracting coal bed gas removing coal dust and vapor, and coal bed gas is made to easily facilitate the process operations such as subsequent delivery, storage and post-processing operation.
Description
Technical field
The invention belongs to Coal-seam Gas Recovery Technologies fields, and in particular to a kind of collecting method of coal bed gas.
Background technology
Coal bed gas is commonly called as " gas ", it refers to being stored in coal seam using methane as main component, to be adsorbed on matrix of coal
Based on grain surface, the hydrocarbon gas that is partly free in coal hole or is dissolved in coal seam water, be the associated minerals resource of coal, belong to
Unconventional gas.
The coal bed gas extracted from gas well contains coal dust and vapor, is unfavorable for subsequent delivery, storage and post-processing
Operation needs to carry out pretreatment operation.
Invention content
The purpose of the present invention is to provide a kind of collecting method of coal bed gas, can after extracting coal bed gas to coal bed gas into
Row removes coal dust and vapor, and coal bed gas is made to easily facilitate the process operations such as subsequent delivery, storage and post-processing operation.
To achieve the above object, the present invention provides the following technical solutions：
A kind of collecting method of coal bed gas, includes the following steps：
Step（1）：By the coal bed gas extracted in coal bed gas well by the drier equipped with drier, being done to coal bed gas
It is dry to remove water process；
Step（2）：It will be through step（1）The coal bed gas obtained after processing is passed through in primary filter, and preliminary mistake is carried out to coal bed gas
Filter is handled；
Step（3）：It will be through step（2）The coal bed gas obtained after processing is passed through in high efficiency particulate air filter, and smart filtering is carried out to coal bed gas
Processing；
Step（4）：By step（3）The coal bed gas obtained after processing is imported in storage tank and is stored.
Preferably, step（1）Described in drier be anhydrous calcium chloride.
Preferably, step（2）Described in primary filter be nylon net filter device.
Preferably, step（3）Described in high efficiency particulate air filter be ultra-fine fibre glass paper filter.
The beneficial effects of the invention are as follows：Coal bed gas is first subjected to dehydration and drying processing, drier environment-friendly high-efficiency, and can be with
It repeatedly uses, use cost is low.Then the contaminant filter of the greater particle size in coal bed gas is fallen by primary filter, then
Smart filtering is carried out using high efficiency particulate air filter, is efficiently removed through the coal dust impurity in coal bed gas, using double-filtration, filter efficiency
Height, processing speed are fast.
Specific implementation mode
In order to make content of the present invention easily facilitate understanding, With reference to embodiment to of the present invention
Technical solution is described further, but the present invention is not limited only to this.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained without making creative work belongs to the model that the present invention protects
It encloses.
A kind of collecting method of coal bed gas, includes the following steps：
Step（1）：By the coal bed gas extracted in coal bed gas well by the drier equipped with drier, being done to coal bed gas
It is dry to remove water process；
Step（2）：It will be through step（1）The coal bed gas obtained after processing is passed through in primary filter, and preliminary mistake is carried out to coal bed gas
Filter is handled；
Step（3）：It will be through step（2）The coal bed gas obtained after processing is passed through in high efficiency particulate air filter, and smart filtering is carried out to coal bed gas
Processing；
Step（4）：By step（3）The coal bed gas obtained after processing is imported in storage tank and is stored.
Preferably, step（1）Described in drier be anhydrous calcium chloride.
Preferably, step（2）Described in primary filter be nylon net filter device.
Preferably, step（3）Described in high efficiency particulate air filter be ultra-fine fibre glass paper filter.
Coal bed gas is first subjected to dehydration and drying processing, drier environment-friendly high-efficiency, and can be repeatedly used, using at
This is low.Then the contaminant filter of the greater particle size in coal bed gas is fallen by primary filter, reuses high efficiency particulate air filter progress
Essence filtering, is efficiently removed through the coal dust impurity in coal bed gas, and using double-filtration, filter efficiency is high, and processing speed is fast.First carry out
Except water process, be conducive to the filter operation of follow-up coal bed gas, avoid moist coal dust from pasting on filtration core, reduce the effect of filtering
Rate reduces process difficulty.
