Description
Technical field
The utility model relates to the pipeline coal transporting water delivery process unit under a kind of large drop ground potential condition, can be widely used in long-distance transportation through pipeline coal serous system, belong to coal slurry pipeline Technology field.
Background technology
In long-distance pipeline coal engineering, the feed coal of head end need be mixed with water and grind to form suitable coal slurry, then be forced through pipe long-distance through pump and be delivered to terminal, to be supplied raw materials coal by the terminal dewater plant rear line that dewaters again, the water deviate from recycles on the spot after needing further purifying treatment or arranges outward, but the expense of purifying waste water is very high, and head end on the spot water intaking can take local water resources.
Prepare at pipeline head end the water quality requirement that coal slurry adopts not high, completely can the dehydration of recycle terminal time the water deviate from.If the elevation of pipeline head end and terminal have large drop physical features and head end is in high-land point time, send the water pump of duct end back to pipeline head end, energy consumption high cost is also high; But when the elevation of pipeline head end and terminal has large drop physical features and head end is in physical features low spot, the glassware for drinking water deviate from during the dehydration of recycle terminal has larger technical superiority and cost advantage.
Summary of the invention
In view of this, the purpose of this utility model is to provide the pipeline coal transporting water delivery process unit under a kind of large drop ground potential condition, when the elevation of pipeline head end and terminal has large drop physical features and head end is in physical features low spot, utilize the large drop physical features of long-distance pipe head end and terminal, the water deviate from when terminal being dewatered is from flowing back into head end recycle.
The technical scheme in the invention for solving the above technical problem is: the pipeline coal transporting water delivery process unit under a kind of large drop ground potential condition is primarily of pulp mill, head end slurry can, high-pressure coal pulp pump, convey coal pipe, terminal slurry can, dewater plant, coal yard, terminal pond, water pipe, head end pond connects to form in certain sequence, described pulp mill is connected with described head end slurry can top by pipeline, described head end slurry can tank skin outlet at bottom pipe is connected with described high-pressure coal slurry pump intake, described high-pressure coal slurry pump discharge and described convey coal pipe one end adopt Flange joint, the described convey coal pipe the other end is connected with described terminal slurry can top, be connected with described dewater plant by pipeline bottom described terminal slurry can tank skin, described dewater plant is connected with described coal yard by transfer roller, described dewater plant is connected with top, described terminal pond by pipeline, described terminal basin bottom is connected with top, described head end pond by described water pipe, described head end basin bottom is connected with described pulp mill by pipeline.
The black water in described head end pond is by Cemented filling to described pulp mill, feed coal is prepared into coal slurry with black water after described pulp mill mixes, the coal slurry that described pulp mill prepares enters in described head end slurry can by pipeline, the coal slurry gravity flow of described head end slurry can enters described high-pressure coal pulp pump, coal slurry is transported in described terminal slurry can through described convey coal pipe by described high-pressure coal pulp pump, the coal slurry of described terminal slurry can is by Cemented filling extremely described dewater plant, the coal slime that described dewater plant is deviate from is delivered to described coal yard through transfer roller, the black water that described dewater plant is deviate from is by Cemented filling to described terminal pond, the black water in described terminal pond by described water pipe because physical features flows automatically to from high to low described head end pond, the black water in described head end pond again by Cemented filling to described pulp mill with feed coal mixed pulp, so far, the black water that dewater plant is deviate from described in duct end reaches the object of recycle.
The beneficial effect of this coal slime pulping process device: the large drop physical features utilizing long-distance pipe head end and terminal, the water deviate from when terminal being dewatered is from flowing back into head end recycle, not only avoid and fetch water on the spot at pipeline head end, and save process procedure and the expense of the further purifying treatment of the water deviate from by dewater plant at duct end, this process unit efficient energy-saving, safe and reliable.
