Distributed coal water dispatching method and system

Abstract

The invention discloses a distributed coal water dispatching method and system. The method comprises the following steps: controlling the state of water supply to sedimentation tanks by a water pump in a water collecting well according to a first early-warning liquid level signal fed back by at least one water collecting well liquid level meter; according to liquid level signals fed back by a plurality of sedimentation tank liquid level meters, controlling a water pump in one sedimentation tank with a liquid level higher than a second early-warning liquid level to supply water to one sedimentation tank with a liquid level lower than the second early-warning liquid level; and controlling water pumps in the sedimentation tanks to supply water to a treatment tank through combined consideration of the sedimentation duration of each sedimentation tank and a preset drainage period so as to treat the coal water in the treatment tank according to a preset manner. A processor is used for monitoring the liquid level condition of the coal water in real time through each water collecting well liquid level meter and each sedimentation tank liquid level meter, so coal water dispatching between the water collecting well and the sedimentation tanks is achieved, and coal water dispatching between the sedimentation tanks and the treatment tank is achieved through combined consideration of the sedimentation duration of each sedimentation tank and the preset drainage period; and thus, corresponding water pumps are controlled to achieve coal water dispatching among the water collecting well, the sedimentation tanks and the treatment tank, and maximum water storage efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of coal water treatment, in particular to a distributed coal water scheduling method and system. Background technique [0002] In the prior art, each water collecting well of the coal water treatment system uses its own liquid level as the basis or manual judgment to control whether the coal water in the water collecting well pumps water to the secondary sedimentation tank. The start and stop of the water collecting well pumps are independent of each other. There is no linkage function between the water collection wells, which leads to the weak dispatching ability of the coal water system. The coal water treatment system is very prone to coal water overflow in some water collection wells, making it difficult to fully utilize the water storage performance of the water collection wells and sedimentation tanks of the coal water system. , the overall effectiveness of the coal-water treatment system cannot be bro...

[0002] In the prior art, each water collection well of the coal water treatment system uses its own water level as the basis or manual judgment to control whether the coal water in the water collection well pumps water to the secondary sedimentation tank. The start and stop of the water collection well pumps are independent of each other. There is no linkage function between the water collection wells, which leads to the weak scheduling ability of the coal water system, and the coal water treatment system is very prone to coal water overflow in some water collection wells, making it difficult to fully utilize the water storage performance of the water collection wells and sedimentation tanks of the coal water system , the overall effectiveness of the coal-water treatment system cannot be brought into full play, how to realize the linkage of each unit of the coal-water treatment system so as to fully exert the overall efficiency of the coal-water system has become a research hotspot in the industry
