No matter industry or it is civilian gradually replace with natural gas, thus having raised vigorous coal, to change fate dynamic.In city, natural gas
It is very ripe managing defeated system, but the extensive country regions, always without the defeated system of natural gas tube, therefore also to establish corresponding
The defeated system of natural gas tube.Coal bed gas will pass through gas production, gas collection, purification, gas transmission, gas storage, gas transmission pipeline net work entrance from exploitation to user
User terminal, a defeated system of complete natural gas tube are the intermediate engineerings with connecting air source with user.Keep the defeated system of coal seam tracheae
The stabilization safe operation of system is our technical problems to be solved.Whole device main material is the pipeline of various bores, mainly
Engineering concentrate on the laying of pipeline.Managing will consider the problems of in defeated system operation inside mainly pipeline service life and pipeline
Cleaning problems.The source of coal bed gas is mainly coal mining, due to the particularity of exploiting colliery technique, is contained in coal bed gas big
The dust of amount, small water droplet or even coal cinder, for these solid matters once entering in pipeline, very easy deposition forms damping block,
If in conjunction with moisture long time sedimentation, gradually forms aggregate and block pipeline, influence air input efficiency.It would therefore be desirable to solve
Certainly gas pipeline internal solids clear up problem, to ensure the operation steady in a long-term of the defeated system of coal seam tracheae.
Invention content
The technical issues of present invention is in order to solve gas pipeline internal cleaning present in current coal bed gas pipeline, gives
A kind of coal bed gas delivery pipeline cleaning plant is gone out.

Cleaning wheel, the disc cutterbar for cleaning wheel shaft and being equipped with arc are connected, the disc cutterbar is equipped with several pointed tooths.
When encountering more hard deposit, disc cutterbar high speed rotation can smash deposit, the powder after then smashing
As air-flow is floated to, next treating stations filtering, the design can clear up the larger barrier of volume to dirt.
The present apparatus can utilize the pressure of the high-pressure gas stream in delivery of fuel gas, driving helical blade rotation, helical blade
Rotation changes power direction by worm and gear, becomes the power source of the power and cleaning that drive the present apparatus to advance.Pass through simultaneously
Telescopically adjustable cross frame is adapted to different tube diameters variation, and the design of universal shaft coupling is adapted to the change of pipeline bend
Change.
Overall construction design of the present invention is reasonable, long-term inside pipeline can over long distances work, and need not provide additional dynamic
Power and manpower, need not also stop the supple of gas or steam maintenance cleaning, and easy to use, work efficiency is high.Periodically inspection cleaning in the duct, avoids coal
Block accumulates, and ensures that gas pipeline is unobstructed.
