DETAILED DESCRIPTION

[0033] The utility model is further illustrated below in combination with the drawings and examples.

[0034] As Figures 1-6As shown, a waste liquid collecting device for an online automatic water quality monitoring station comprises a common main pipeline 1, which is connected to waste liquid outlets of a COD module 2, a high index module 3, an ammonia nitrogen module 4, a total phosphorus module 5 and a total nitrogen module 6 through branch pipelines 9 respectively, and a waste liquid collecting barrel 7 is connected to an outlet end of the common main pipeline 1 through a pipeline. The common main pipeline 1 is arranged to be inclined downward along a liquid flow direction. The gravity is utilized to promote the gravity flow of the waste liquid, avoid the accumulation of the liquid in the pipeline, reduce the risk of blockage, and reduce the energy consumption without additional power equipment. In addition, the waste liquid of the multiple modules is concentrated in one place, which is convenient for storage and transportation, and is also conducive to risk control and less likely to leak.

[0035] An angle between the common main pipeline 1 and the horizontal direction is 5-10°. While ensuring the smooth flow of the waste liquid, the angle is configured to avoid too large slope to cause too fast flow speed to wash the pipeline, or too small slope to cause poor flow, so as to balance the flow speed and energy consumption.

[0036] A lower part of the waste liquid collecting barrel 7 is provided with a tray 8. The tray 8 can receive the waste liquid dripping from the bottom of the collecting barrel or a valve, so as to prevent the waste liquid from directly dripping to the ground to cause secondary pollution and improve the environmental friendliness of the device.

[0037] The branch pipeline 9 comprises a vertical part 10, a bending part 11 and a connecting part 12. The waste liquid first reaches the bending part 11, is buffered and then enters the common main pipeline 1 from the connecting part 12, so as to reduce the impact on the common main pipeline 1, prolong the service life of the pipeline and reduce the failure.

[0038] An angle between the connecting part 12 and a horizontal projection of the common main pipeline 1 is 30-60°. The oblique design can reduce the interference of the waste liquid of each branch pipeline 9 when the waste liquid flows into the main pipeline, reduce the turbulence degree, and avoid uneven mixing of the waste liquid or pressure fluctuation in the pipeline.

[0039] Inner walls of the bending part 11 are provided with a plurality of tapered protrusions 13. The tapered protrusions 13 can destroy the laminar flow state of the waste liquid at the bending part, increase the turbulence intensity, prevent the deposition of suspended solids or crystalline substances on the inner wall of the pipeline, and keep the pipeline unblocked for a long time.

[0040] An inner side of a bottom of the connecting part 12 is provided with a plurality of flow baffles 14. The flow baffles 14 in the embodiment are arc-shaped flow baffles. The protruding direction of the arc-shaped flow baffles 14 is arranged to be toward the inflow direction of the waste liquid. The waste liquid will not be stored at the flow baffles 14. The flow baffles 14 can slow down the flow speed of the waste liquid in the connecting part 12 and reduce the impact when the waste liquid enters the common main pipeline 1.

[0041] An angle between the vertical part 10 and the bending part 11 is 120-150°. The impact energy of the waste liquid when the waste liquid turns from the vertical part 10 to the bending part 11 is reduced, the pipeline wear is reduced, and the problem of bubble retention caused by the right-angle bending is avoided.

[0042] The waste liquid collecting barrel 7 is provided with a liquid level sensor 15, and the outlet end of the public main pipeline 1 is provided with a cut-off valve 16, and the liquid level sensor 15 and the cut-off valve 16 are interlocked to a control system. Through real-time monitoring of the liquid level and automatic cut-off of the valve 16, overflow of the waste liquid collecting barrel 7 can be prevented, intelligent management without attendance is realized, and system safety and reliability are improved.

[0043] It should be understood that the embodiments are only used for illustrating the present application and are not used for limiting the scope of the present application.
