Example 1

The embodiment discloses a water resource collecting and recycling system, which comprises a raffinate recycling water pipeline, a carbon fiber condensate pipeline, a pure water overhead tank 8 and a pure water tank as shown in figure 1. In the embodiment, the raffinate recovery water pipeline and the carbon fiber condensate pipeline are connected in parallel and then enter the original phosphoric acid tank recovery water pipeline 11, the original phosphoric acid tank recovery water pipeline 11 is connected to the pure water high-level tank 8, and the blind plug 3 is additionally arranged at the outlet of the original phosphoric acid tank recovery water pipeline 11. The raffinate and carbon fiber condensate are passed into the pure water head tank 8 rather than into the phosphoric acid tank as it were. The position of the pure water high-level tank 8 is higher than that of the pure water tank, and the pure water high-level tank 8 is communicated with the pure water tank. And allowing the raffinate water and the carbon fiber condensate to enter a pure water overhead tank for secondary oil-water separation. The separated water phase is arranged at the bottom of the pure water overhead tank 8 and discharged to the pure water tank, and the separated oil phase is arranged at the top of the pure water overhead tank 8.

In this embodiment, pure water elevated tank 8 is linked together through U type return bend 7 with pure water tank, be equipped with blow-down pipe 6 on the U type return bend 7, the height at blow-down pipe 6 top is greater than pure water elevated tank 8's height. The U-shaped bent pipe 7 prevents the oil phase from being mixed into the pure water tank at too high flow speed when the water phase is drained, and the drain pipe 6 enables the drain pipe to be communicated with the atmosphere, so that air resistance is prevented from being generated when the water phase is drained.

In this embodiment, the raffinate recovery water line and the carbon fiber condensate line are connected to the pure water elevated tank 8 through the raw phosphoric acid tank recovery water line 11, and the outlet of the raw phosphoric acid tank recovery water line 11 is additionally blind. The communicating pipe of the original phosphoric acid tank recovery water pipeline 11 and the pure water tank is provided with a communicating gate valve 2. In the process of recycling water resources, the communication gate valve 2 is always kept in a closed state. The water to be recovered is first separated into water and oil in the pure water overhead tank 8 and then enters the pure water tank.
