Accompanying drawing explanation
Fig. 1 is example structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, the purifying process water system in the present embodiment comprises recirculated water separating tank 3, rectifying tower 5, interchanger 8, water cooler 9 and return tank 10.
Be connected to the centre entrance of recirculated water separating tank 3 after the recycled process water first transfer lime 1 from Heat Exchanger in Circulating Water System 8 shell side and the second transfer lime 2 from hydration reactor effluent quantizer water bag link together, the top exit of recirculated water separating tank 3 connects extraneous upstream device.
Recirculated water separating tank 3 outlet at bottom contracts out after mouth links together with debutenizer return tank 4 water and connects rectifying tower 5 middle feed entrance, the tower bottom outlet of rectifying tower 5 connects tower reactor pump 7 entrance, tower reactor pump 7 exports the shell side inlet connecting interchanger 8, and the shell-side outlet of interchanger 8 connects extraneous upstream device.
The tower top outlet of rectifying tower 5 connects the shell side inlet of water cooler 9, and the shell-side outlet of water cooler 9 connects the feed(raw material)inlet of return tank 10; The top exit of return tank 10 has the pipeline 12 being disposed to torch pipe network.The liquid outlet of return tank 10 connects reflux pump 11 entrance, and the outlet of reflux pump 11 has two-way, and a road connects the spray inlet on rectifying tower 5 top, and another road connects extraneous upstream device.
The bottom of rectifying tower 5 is also provided with bypass outlet, and this bypass outlet connects reboiler 6, and the outlet of reboiler 6 connects the reflux inlet of rectifying tower 5.Reboiler 6 in the present embodiment is thermosyphon reboiler 6.
Principle of work is described below:
The water that the recycled process water that self-circulating water interchanger 8 shell side comes comes with hydration reactor effluent quantizer water bag merges together rear feeding recirculated water separating tank 3, and butylene in process water major part is vaporized and enters debutenizer from top exit and reclaim in recirculated water separating tank 3.What process water was discharged from recirculated water separating tank 3 outlet at bottom with debutenizer return tank 4 water bag merges together rear feeding rectifying tower 5 middle feed entrance containing organic water.
