Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in figure 1, the air-entrapping flotation device capable of improving the oil removal rate comprises a horizontal tank body 1, and a plurality of vertical partition plates 2, a primary oil receiving groove 3, a primary oil receiving hopper 4 and a secondary oil receiving funnel 5 which are arranged in the horizontal tank body 1, a liquid inlet 6 at the left end of the horizontal tank body 1 and a scraper motor 7, an air outlet 8 is arranged at the top, a plurality of ejectors 9, a circulating port 10 and a liquid outlet 11 are arranged at the bottom, an air-float circulating pump 12, a Venturi tube 13 and a circulating tube 14 are also arranged below the horizontal tank body 1, the liquid inlet end of the air-floating circulating pump 12 is communicated with the circulating port 10 through a pipeline, the liquid outlet end is communicated with the ejector 9 through a circulating pipe 14, the gas outlet 8 is communicated with a circulating pipe 14 through a Venturi tube 13, a secondary oil receiving funnel limiter 15 is arranged in the secondary oil receiving funnel 5, and a liquid level meter 16 is arranged at the right end of the horizontal tank body 1.
The utility model discloses a theory of operation: the jet induced air floating machine is generally a multistage series structure, four ejectors and corresponding four-stage flotation cavities are adopted, partial treated water is sent to a nozzle through a circulating pump by utilizing the principle of the ejectors, negative pressure is formed in a suction chamber of the ejectors when the water is ejected from the nozzle at a high speed, gas is sucked into the chamber, the gas is sheared into tiny bubbles when gas-water mixed liquid passes through a mixing section at a high speed, and the bubbles float in the air floating chamber and carry oil beads and solid particles adhered to the bubbles out of the water surface to be removed.
In this embodiment, as shown in fig. 2 and 3, the secondary oil receiving funnel stopper 15 has a specific structure including a blind plate 151, a connecting rod 152 and two steel plates 153, wherein the connecting rod 152 is axially disposed on the blind plate 151, the two steel plates 153 are axially fixed to one end of the connecting rod 152 far away from the blind plate 151, the connecting rod 152 is a steel pipe, and the blind plate 151 is provided with a fixing plate 154.
Wherein the lifting and lowering of the secondary oil receiving funnel 5 are realized by rotating the funnel, and the rotary part is a cross-shaped steel bar above the funnel. In order to realize the limiting function, the funnel does not rotate along with the shaking of the ship body and the impact of liquid flow, the connecting rod 152 is located at the non-center of the blind plate 151, and an eccentric connecting mode is adopted, namely, a steel pipe used for connecting the fixed steel plate 153 and the blind plate 151 is welded on the blind plate in an eccentric welding mode.
The utility model discloses a use of stopper, 1, promote air entrainment flotation device (marine) deoiling rate, reduce the output loss because of the undulant lead to of quality of water. The secondary oil collecting funnel limiter is additionally arranged on the air-entraining flotation device, so that the oil removal rate is obviously stabilized at a relatively high level, and the water quality is greatly improved;
2. can save a large amount of cleaning cost of the tank body of the air-entraining flotation device. The second-stage oil receiving funnel shakes along with the ship body and impacts water flow, and oil cannot be received when the second-stage oil receiving funnel rotates to the highest position, so that oil sludge is generated. In order to discharge oil sludge in the tank and recover the secondary oil recovery function, an online oil sludge discharge method is adopted. Because the viscosity of the oil sludge is high, the diaphragm pump is difficult to pump, so that the thickest oil sludge is discharged from the flange position at the bottom of the tank body through the secondary oil recovery pipeline, and the rest thinner oil sludge is pumped to the oil sludge tank through the diaphragm pump. After the limiter is additionally arranged, the phenomenon of oil sludge accumulation caused by incapability of collecting oil is avoided, the field operation difficulty is reduced, and meanwhile, the cost for cleaning the air-entraining flotation device is greatly saved.
3. The water quality of the injected water is improved, the development efficiency of the oil field water injection is greatly improved, and the operation cost of measures such as acidification and injection increase of a water injection well is reduced. After the secondary oil collecting funnel is additionally arranged, the PPM (PPM) of the outlet water quality is greatly reduced, the treatment pressure is reduced for a downstream walnut shell filter, and the treatment efficiency is improved.
4. The quality of the discharged seawater is improved, and a response company makes a call of 'blue Bohai sea, green oil field'.
The above description is not intended to limit the present invention in any way, and the present invention has been disclosed in the above embodiments, but is not intended to be limited thereto, and any person skilled in the art can make some changes or modify equivalent embodiments with equivalent changes when using the technical content disclosed above without departing from the technical scope of the present invention.
