Embodiment 1
[0022] Embodiment 1: interception, separation and recovery of insoluble light pollutants, taking diesel and gasoline as examples.
[0023] as attached figure 2 The operation shown simulates an emergency treatment with a gate spacing of 500mm and a nozzle diameter of 50mm. The simulation test in the water tank shows that: when the pollutant flow is smooth, almost all light pollutants float on the water surface, and more than 90% of them can be intercepted through the first gate, and there is almost no floating oil film on the water surface in front of the second gate; When the water flow is violently turbulent, a small amount of oil will flow through the first gate with the water flow and come to the second gate. After the water flows through the energy dissipation effect of the first gate, it will become gentle, and the oil will float to the water surface. The second gate can better complete the interception and separation of oil. By combining the test data of the two gates,...
Embodiment 2
[0027] Embodiment 2: interception, separation and recovery of insoluble heavy pollutants, taking nitrobenzene and carbon dichloride as examples
[0028] as attached image 3 The operation shown simulates emergency treatment, where the distance between the gates is 500mm and the diameter of the diversion pipe is 50mm. The simulation test in the tank shows that when the water flow is smooth, almost all heavy pollutants will be deposited to the bottom of the water, and more than 90% of them can be intercepted through the first gate, and almost no pollutants appear before the second gate; When the water flow is violently disturbed, some pollutants will flow through the first gate with the water flow and come to the second gate. The energy dissipation effect of the pollutants and water flowing through the first gate will become gentle, and the pollutants will Deposited to the bottom of the water, the interception and separation of heavy pollutants can be well completed at the seco...
Embodiment 3
[0032] Example 3: Simultaneous interception, separation and recovery of insoluble heavy and light pollutants, taking diesel oil and carbon dichloride as examples.
[0033] as attached Figure 5 The operation shown simulates an emergency treatment with a gate spacing of 500mm and a nozzle diameter of 50mm. The simulation test in the water tank shows that diesel oil and carbon dioxide will dissolve each other after mixing. When the water flow is gentle, most of them will sink to the bottom of the water, and more than 80% of them will be intercepted by the first gate. Before, there are very few pollutants; when the water flow is violently disturbed, some pollutants will flow through the first gate with the water and come to the second gate. The pollutants will be deposited to the bottom of the water, and the second gate can well complete the interception and separation of pollutants.
