Abstract
The utility model provides a compressed natural gas and coal mine gas mixing device. The device comprises a mixer, a coal mine gas pipeline, a compressed natural gas pipeline, a mixture gas pipeline and a control panel, wherein, the mixer adopts a sealed tank body; a spoiler net is mounted in the tank body; the coal mine gas pipeline provided with a filter, a cold dryer, a gas methane analyzer is connected with the mixer; the compressed natural gas pipeline provided with a decompression device and a regulating valve is connected with the mixer; and the mixture gas pipeline provided with a mixture gas methane analyzer is connected with the mixer; and the gas methane analyzer, the regulating valve and the mixture gas methane analyzer are respectively connected with the control panel through leads. The mixing device has the advantages of simple structure, safety, reliability and high applicability, is easy for operation, is convenient for maintenance, and supplies mixture gas to industrial furnaces or residents for use after mixing the coal mine gas and the natural gas and achieving calorific value balance, thereby effectively utilizing natural resources, and facilitating environmental protection.
Description
(1) technical field
The utility model relates to the application technology of coal mine mash gas, particularly a kind of compressed natural gas and coal mine mash gas mixing arrangement.
(2) background technology
Before coal mining, at first will be existing the Device in Gas in the coal seam to concentrate discharging.But contain a large amount of methane in the Device in Gas, directly be discharged in the atmosphere, can cause greenhouse effects, contaminated environment and waste resource atmosphere.Because the methane content instability in the Device in Gas can not directly be burnt.Therefore need a kind of device to change the methane content of Device in Gas, methane content can be carried in normal stable status, the assurance user can be burnt normally.Contain 95% methane in the natural gas, utilize natural gas and Device in Gas to mix, can improve the concentration of methane.If there are sources of the gas such as compressed natural gas the locality, just can utilize compressed natural gas to come the balance coal mine mash gas.
(3) utility model content
The purpose of this utility model is at above-mentioned existing problems, and a kind of simple in structure, safe and reliable, convenient maintenance, compressed natural gas and coal mine mash gas mixing arrangement that applicability is strong are provided.
The technical solution of the utility model:
A kind of compressed natural gas and coal mine mash gas mixing arrangement, by blender, the coal mine gas air pipe, the compressed natural gas pipeline, gaseous mixture pipeline and control panel are formed, blender is a sealed shell of tank, the flow-disturbing net is installed in the tank body, the coal mine gas air pipe is provided with filter, cooling driers is connected with the Device in Gas methane analyser and with blender, the compressed natural gas pipeline is provided with decompressor and is connected with control valve and with blender, the gaseous mixture pipeline is provided with the gaseous mixture methane analyser and is connected the Device in Gas methane analyser with blender, control valve is connected with control panel by lead respectively with the gaseous mixture methane analyser.
Working procedure of the present utility model:
Be displaced into ground by the Device in Gas of discharging in the coal seam through air exhauster, enter the coal mine gas air pipe, Device in Gas is filtered foreign material through filter, through behind the cooling driers moisture in the Device in Gas is got rid of again, enter in the blender, measure the concentration of methane in the coal mine mash gas by the Device in Gas methane analyser.High-pressure natural gas from natural gas sled car or storage tank enters into blender through behind the depressurized system, and the flow that control valve is used for regulating natural gas was set before natural gas enters into blender.Two kinds of gases mix the back by the output of gaseous mixture pipeline in blender, utilize the gaseous mixture methane analyser on the output pipe to measure the methane content that mixes in the gas, open degree by control panel control and regulation valve, so just can regulate the ratio of natural gas and Device in Gas automatically, methane content is normal after keeping mixing gas.
The utility model has the advantages that: the operation simple in structure, easy of this mixing arrangement, safe and reliable, easy to maintenance, applicability is strong; by coal mine mash gas and natural gas is mixed and reach after the calorific value balance for Industrial Stoves or resident's use; can not only effectively utilize natural resources, and help environmental protection.
