Embodiment
As shown in Figure 1, the present invention's air draft self-sucking device that circulates, include tank body 11, tank interior is provided with water guide cap 3 and dividing plate 10, water guide cap 3 welds mutually tank body is divided into dividing plate 10, lower two chambeies, the tank body top is equipped with auto-control exhaust device 4, tank body epicoele inside is equipped with returns water wind shield 6, the outside side of tank body epicoele is connected with water injecting pipe gland 2, the outside opposite side of tank body epicoele is equipped with circulation intake pipe 9, the position that tank body cavity of resorption outside is positioned at circulation intake pipe 9 belows is provided with outlet pipe 12, the below of water guide cap 3 is provided with suction sleeve 1, suction sleeve 1 is connected with sparger 8 by air inducing conduit 5, sparger 8 is by upper, lower two chambeies connect, be provided with backwater air inducing injection pipe 7 in sparger 8, the top of backwater air inducing injection pipe 7 is placed in to be returned in water wind shield 6.
As shown in Figure 2, described auto-control exhaust device 4 includes gravity check valve 43, sealing pad 44, shell 45, floating drum 46 and floating drum collet 48, shell 45 is connected with tank body 11 by flange, floating drum collet 48 is arranged on the top of tank body, floating drum 46 is placed on floating drum collet 48, the top of floating drum 46 is equipped with sealing pad 44, and the top of shell 45 is equipped with gravity check valve 43.
Shell 45 is provided with seal washer 47 with the joint of tank body 11.
Below in conjunction with Fig. 3, using method of the present invention and working principle thereof are described below:
1, check periodical feeding gate valve 19, and open it; Production water supply valve 21 is closed simultaneously.
2, open water injecting pipe gland 2, and fill with water in pipe, then gland is tightened.
3, start water pump, allow water iterative cycles between the epicoele of circulating exhaust self-sucking device and cavity of resorption.Water enters water pump from the cavity of resorption of exhaust self-sucking device, flows into again subsequently the epicoele of air draft self-sucking device from exit of pump, will cause the epicoele water level constantly to rise, and end cavity pressure constantly descends, thereby formed the pressure reduction between two chambeies, and this pressure reduction can strengthen again gradually.
4, because the former water of epicoele is few, and space is larger, so water is slower in the epicoele flowing velocity, so the time that water stops at epicoele is longer, for gas, moisture from abundant guarantee is provided.The air be separated, have again certain pressure, just can go back to nature by the auto-control exhaust device 4 on top.
5,, when the epicoele water surface surpasses backwater air inducing injection pipe 7, epicoele water will turn back to chamber, the end with the core pipe 7 by the backwater wine guide at a high speed.Just because of this draw attached effect continue carry out, make the air in the suction sleeve 1 of circulation air draft self-sucking device, by air inducing conduit 5 by injection to cavity of resorption, then be transported in epicoele and go by water pump again.Due to by this upper and lower circulation repeatedly, all air in suction sleeve all are discharged in atmosphere and are gone successively the most at last.
6, in the water pump periodic duty stage, can hear the sound of air from auto-control exhaust device top discharge during beginning, when air is drained, sound just stops automatically, at this moment can implement formal and net operation.
7, close periodical feeding gate valve 19, and then open production water supply gate valve 21 and just can go into operation smoothly.
In conjunction with Fig. 2, Fig. 3, the function of auto-control exhaust device is described:
If water level rises in the air exhausting device shell, must cause floating drum 46 levitatings, when being raised to top sealing pad 44 will with end in contact under the outlet pipe of gravity check valve lower end, air draft is stopped.
When circulation air draft self-sucking device quits work, in the auto-control exhaust device, in negative pressure state, at this moment gravity check valve 43 wants definitely tight, the inaccurate gas leak phenomenon that produces.
