Device for pipeline coal transporting water delivery technology under big drop relief condition

The utility model discloses a device for pipeline coal transporting water delivery technology under big drop relief condition, but the wide application belongs to slurry pipeline technology technical field in long distance pipeline carries the slurry system this device is mainly by the pulp mill, head end mud storage tank, and high-pressure slurry pump, the coal chute way, terminal mud storage tank, dehydration factory, the coal yard, the terminal pond, conduit, the head end pond connects to form according to a definite sequence, and this device utilizes the big drop relief at long distance pipeline head end and terminal, and when the elevation at pipeline head end and terminal had big drop relief and head end to be in the relief nadir, the water of deviating from when dewatering the terminal flow automatically and gets back to head end cyclic utilization, has not only avoided fetching water on the spot at the pipeline head end, had saved in addition at duct end will dewater water that the factory deviates from further purification treatment's technology link and expense, this process units energy-conservation high efficiency, safe and reliable
