The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
Embodiment 1:
The circular water treating system of water washing formula waste gas purification apparatus as shown in Figure 2, comprise feed pump 1, water washing formula waste gas purification apparatus and water tank, about comprising, separates by described water tank pond 3 and the oil-water separation tank 4 that arranges, pond 3 and oil-water separation tank 4 are communicated with by the profit tube connector 10 on top, be provided with water level controller 11 in the oil-water separation tank 4, water level controller 11 tops are provided with oil exit pipe, water level controller 11 belows are provided with pump mouth, this pump mouth connects and separates water pump 6, separate water pump 6 and separate water pipe 12 and be connected, the delivery port that separates water pipe 12 is installed in 3 tops, pond, like this, separating water pump 6 can be from drawing water in the oil-water separation tank 4 and sending water to pond 3 by separating water pipe 12; Feed pump 1 draws water from pond 3 and delivers to water washing formula waste gas purification apparatus, and the water after waste gas purification apparatus uses drains back to pond 3 after by return pipe 7, screen pack 8 again; Wherein, water level controller 11 is connected with the control device that separates water pump 6.
In the present embodiment, the height of described profit tube connector 10 is not less than the height of oil exit pipe.On the connecting water pipe between described feed pump 1 and the pond 3 stop valve A2 is installed, stop valve B5 is installed on the pump mouth of described oil-water separation tank 4.Described profit tube connector 10 is a right angle bend pipe, and 3 one sides are the transverse tube mouth in the pond for it, and it is the vertical tube mouth in oil-water separation tank 4 one sides.Draining valve 9 is housed on the described oil exit pipe.
During use, slurry is pumped into the scrubbing tower of waste gas purification apparatus by stop valve A2 by feed pump 1, waste water after the washing (containing the particles such as oils material and fiber) is back to pond 3 through return pipe 7, particle is filtered net 8 interceptions, water and oily substance flow into circulating water pool 3, because water heavy oil is light, so oily substance floats on the water surface of circulating water pool 3, when water surface elevation reaches profit tube connector 10 height, oily substance and part water flow into oil-water separation tank 4 through profit tube connector 10, it is oil water mixture in the oil-water separation tank 4, because water heavy oil is light, so oily substance floats on the surface, when water surface elevation reaches certain position in the oil-water separation tank 4, water level controller 11 starts separation water pump 6, the water of oil-water separation tank 4 bottoms is passed through stop valve B5, separating water pipe 12 draws back to circulating water pool 3, when the oily substance liquid level in the oil-water separation tank 4 reaches the oil exit pipe height, just can discharge by oil exit pipe, what so just guaranteed to emit from oil exit pipe is the oily substance of substantially pure, has changed that profit can't separate the situation that causes needing to sneak in a large number in artificial surging oil or the oil water in the former cyclic water tank.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
