In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Aiming at the problem that the usage amount of circulating water in the existing fine coal slime treatment system is large, the filter liquor water circulating pipeline in the existing fine coal slime treatment system is improved, and the usage amount of the circulating water in the whole system is reduced.
Specifically, this example improves to the filtrate water main line of connecting the concentration tank among the current fine coal slime processing system, and to the filtrate water main line of this connection concentration tank, sets up corresponding filtrate water branch pipe way, shunts the filtrate water that produces among the fine coal slime processing system, and all filtrate water that avoid producing all enter into the concentration tank through filtrate water main line.
Referring to fig. 1, there is shown an example of the composition of a filtrate water circulation line for a fine coal slurry system given in this example.
As can be seen from the figure, the filtrate water circulation pipeline 100 for the fine coal slime system mainly includes a main filtrate water pipeline 110, two branch filtrate water pipelines 120, a plurality of control valves 130, and a controller 140.
The main filtrate water line 110 is connected to the concentration tank 200 in the fine coal slurry treatment system to supply the filtrate water generated in the fine coal slurry treatment system to the concentration tank 200.
The specific structure of the main filtered water pipeline 110 and the connection scheme between the main filtered water pipeline 110 and the concentration tank 200 are conventional technologies in the art, and are not described herein again.
On this basis, in the present embodiment, two filtrate water branch pipelines 120 are arranged in parallel for the filtrate water main pipeline 110, and the inlet ends of the two filtrate water branch pipelines 120 and the filtrate water main pipeline 110 synchronously receive filtrate water generated in the fine coal slime treatment system; meanwhile, the outlet ends of the two filtrate water branch pipelines 120 are respectively connected with the equipment 300 which can use the filtrate water outside the concentration tank 200 in the fine coal slime treatment system.
Furthermore, the two filtrate water branch pipes 120 are connected and conducted with the filtrate water main pipe 110 by connecting pipes 121. Preferably, the connection pipes 121 between the two filtrate water branch pipes 120 and the filtrate water main pipe 110 are provided so as to be offset in the longitudinal direction of the filtrate water main pipe.
Further, in this embodiment, the connection pipes 121 between the two filtrate water branch pipes 120 and the filtrate water main pipe 110 are respectively provided with corresponding control valves 130 to control the connection and disconnection of the connection pipes 121, so as to control the connection and disconnection between the two filtrate water branch pipes 120 and the filtrate water main pipe 110.
In cooperation with this, the present embodiment further provides control valves 130 at the outlet ends of the two filtrate water branch pipes 120, so as to control the connection or the disconnection of the two filtrate water branch pipes 120.
Therefore, the two filtrate water branch pipelines 120 which are arranged in parallel and communicated are matched with the corresponding control valves 130, so that the connection and conduction relation between the two filtrate water branch pipelines 120 and the filtrate water main pipeline 110 is controlled, and then whether the filtrate water main pipeline 110 is shunted through the two filtrate water branch pipelines 120 is controlled.
For example, if the control valve 130 at the outlet end of the two filtrate water branch pipes 120 is closed and the control valve 130 at the connecting pipe 121 between the two filtrate water branch pipes 120 and the main filtrate water pipe 110 is opened, the two filtrate water branch pipes 120 all deliver the received filtrate water to the main filtrate water pipe 110 for confluence, and do not form a shunt flow to the main filtrate water pipe 110.
If the control valve 130 at the outlet end of the two filtrate water branch pipelines 120 is opened, and the control valve 130 on the connecting pipe 121 between the two filtrate water branch pipelines 120 and the main filtrate water pipeline 110 is closed, at this time, the two filtrate water branch pipelines 120 will not be conducted with the main filtrate water pipeline 110, the two filtrate water branch pipelines 120 will directly transport the received filtrate water away from the two filtrate water branch pipelines 120, and at this time, a shunt will be formed for the main filtrate water pipeline 110.
In addition, according to the requirement, one filtrate water branch pipeline 120 can be controlled to form shunting on the filtrate water main pipeline 110, and the other filtrate water branch pipeline 120 can form confluence on the filtrate water main pipeline 110.
The specific structure of the filtrate water branch conduit 120 in this embodiment may be the same as the structure of the main filtrate water conduit 110, or other possible alternatives, which are well known to those skilled in the art and will not be described herein.
In addition, it is well known to those skilled in the art how to receive filtrate water and to connect and cooperate with other devices through the filtrate water branch line 120, and the detailed description thereof is omitted.
The control valve 130 is a conventional pipeline control valve scheme or other stable and reliable control valve scheme, and is not limited herein.
The controller 140 in this example serves as a control center for the overall scheme, which controls all the control valves 130 on the entire piping, respectively, to control the closing of the control valves 130.
In cooperation therewith, the control valve 130 can be a corresponding electromagnetic control valve to realize precise control.
The controller 140 may be formed by a reliable and stable PLC, and the specific forming scheme may be a scheme mature in the field and will not be described herein.
In addition, the controller 140 and the corresponding control valve 130 in the present embodiment may be controlled in a remote wireless manner, or may be connected in a wired manner. Preferably, the controller 140 is remotely located in this example and is coupled to the corresponding control valve 130 via a control bus.
By way of example, in the filter liquor water circulation pipeline 100 for the fine coal slime system, when the filter liquor water circulation pipeline 100 is used specifically, the filter liquor water main pipeline 110 serves as a filter liquor water main conveying pipeline and is connected with a concentration tank in the system; the two filtrate water branch pipelines 120 are respectively used for receiving filtrate water of the pressure filter and the plate-and-frame filter press in the fine coal slime treatment system and are communicated with a main selection workshop system in the fine coal slime treatment system, so that the filtrate water of the pressure filter and the plate-and-frame filter press is divided by the two filtrate water branch pipelines 120 to supplement water for the main selection workshop system, the water circulation amount of the concentration tank can be reduced by dividing the filtrate water, the load of a sedimentation system is reduced, and the use efficiency of the concentration tank is more efficient.
Aiming at the scheme of the filtrate water circulation pipeline for the fine coal slime system, the embodiment also provides an improved scheme.
Referring to fig. 2, a filtrate water circulation pipeline modification scheme for the fine coal slurry system is shown. As can be seen from the figure, in the present modification, on the basis of the above-mentioned solution, a corresponding flow sensor 150 is provided at the outlet end of the main filtrate water pipeline 110, and the flow sensor 150 is connected to the controller 140. The two can be connected in a wireless or wired mode.
Thus, the flow rate in the filtrate main line 110 is monitored in real time by the flow rate sensor 150, thereby accurately controlling the amount of filtrate introduced into the concentration tank.
