The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
Referring to fig. 1 and 2, the solid-liquid separation apparatus of the present embodiment includes a cylinder 4, an upper cover 3, and a cyclone air-flotation assembly disposed inside the cylinder 4, wherein the cylinder 4 and the upper cover 3 are detachably connected. The cylinder 4 and the upper cover 3 of the present embodiment are made of stainless steel, and the upper cover 3 and the cylinder 4 are fixedly connected by screws 6.
The cyclone air flotation assembly comprises an oil discharge pipe 21, an inverted conical shell 22, a first cylindrical shell 23, a second cylindrical shell 24, a conical shell 25, an impurity discharge pipe 26, a first water inlet pipe 27, a second water inlet pipe 28 and a V-shaped lower baffle plate 29. The top of the inverted cone shell 22 is fixed and communicated with the bottom of the oil discharge pipe 21, the bottom of the inverted cone shell 22 is fixedly connected with the first cylindrical shell 23, the top of the conical shell 25 is fixedly connected with the second cylindrical shell 24, the bottom of the conical shell 25 is fixed and communicated with the top of the impurity discharge pipe 26, and the first cylindrical shell 23 is sleeved on the outer side of the second cylindrical shell 24. The rotational flow air flotation component is formed by processing stainless steel, so parts are fixed by welding.
The first water inlet pipe 27 and the second water inlet pipe 28 transversely penetrate through the first cylindrical shell 23 and the second cylindrical shell 24, the end parts of the first water inlet pipe 27 and the second water inlet pipe 28 are both in a spiral line type structure, and the turbulence and the disturbance degree of fluid at the water inlet can be weakened through the water inlet pipes with the sections, so that the energy loss in the cylinder body is reduced. The wastewater enters from the first water inlet pipe 27 and the second water inlet pipe 28 of the rotational flow air flotation unit at the same time, and the wastewater enters the rotational flow air flotation unit to generate rotational flow effect. The waste water enters the cylinder body along the tangential inlet at a certain speed, and rotates towards the center while moving downwards under the limit of the inner wall, namely, the waste water is subjected to outer rotational flow; due to the suction of the low pressure at the center of the cylinder and the space limitation of the conical section, the internal fluid rotates upwards to make a rotary motion, namely, an internal rotational flow. As the flow radius decreases, the pressure energy is gradually converted into fluid kinetic energy and energy loss. The waste water is subjected to centrifugal inertia force, centripetal buoyancy force and fluid resistance in the cylinder body, and the 3 forces promote the substances with different densities to be orderly separated in the cylinder body.
Because the density difference of oil, water, gas, sediment etc. under the effect of centrifugal force, the material that density is bigger than water is got rid of on the inner wall of toper shell, discharges from row's miscellaneous mouthful at last, and oil, gas, water are compelled to central zone migration, and tiny bubble carries out oil, the flocculation in the migration in-process in aqueous to realize the enrichment in the central zone of back taper shell, at last through oil outlet pipe, with oil and floc discharge system. Because the oil and the floc are removed under the combined action of air flotation and rotational flow, the treatment time is greatly shortened, the treatment capacity of the equipment is increased, and particularly when the water quality is seriously deteriorated, the equipment can realize quick treatment, thereby achieving the purposes of moderate abundance and double processes.
After a large amount of oil and flocs are removed, the wastewater quickly flows into the upper area of the V-shaped lower baffle from the gap between the first cylindrical shell and the second cylindrical shell, and the water flow speed is quickly reduced due to the volume change of the area, so that the wastewater is very suitable for precipitation and filtration. Therefore, a filtering zone is designed in the upper part of this zone. The slag generated in the filtering area is discharged from the slag discharge port, and the treated water enters the inverted cone-shaped shell and the upper part of the filtering area to form a clear water area and is finally discharged from the water discharge port.
The ratio of the height of the rotational flow air flotation unit to the diameter of the cylinder body is 1.7, the diameters of the first water inlet pipe and the second water inlet pipe are 0.25-0.4 times of the diameter of the cylinder body, and the water inlet speed of the first water inlet pipe and the second water inlet pipe is generally 1-2 m/s.
The bottom of the V-shaped lower baffle plate 29 is provided with a slag discharge port 210, the side surface of the V-shaped lower baffle plate 29 is provided with a sludge collecting hopper, and the bottom of the impurity discharge pipe 26 penetrates through the slag discharge port 210 to discharge impurities. The top of the oil drain pipe 21 penetrates the top of the upper cover 3 to drain oil, and the upper cover 3 is provided with a water outlet 31. The top of the drain pipe 21 communicates with the pressure reducing valve 5.
In order to further improve the solid-liquid separation effect and separate fine impurities, an annular support frame is fixed outside the first cylindrical shell 23 of the solid-liquid separation system of the present embodiment, an annular screen shell 212 made of a screen mesh is fixed on the annular support frame, and the screen shell 212 is filled with a filter material 213. The difference between the outer diameter and the inner diameter of the screen shell 212 is equal to the distance between the inner wall of the cylinder 4 and the outer wall of the first cylindrical shell 23. The screen shell 212 is provided with a feed port 214 and a discharge port 215, and the feed port 214 and the discharge port 215 penetrate through the side wall of the cylinder 4.
In order to further improve the solid-liquid separation effect, the fine impurities can also be separated in the form of a partition plate. An annular support frame is fixed outside the first cylindrical shell 23, and a partition plate for isolating fine impurities is fixed on the annular support frame.
In order to improve the filtering effect, the filler can be flexibly selected according to the water quality of inlet water and the water outlet requirement. When the oil content in the inlet water is higher, the conglomerate filler with high-efficiency oil-removing effect is preferably selected, such as polypropylene corrugated plate, ceramic corrugation, ceramsite filler and the like; when the content of suspended matters in the inlet water is high, inclined plates, inclined tube fillers and the like for accelerating the sedimentation of the suspended matters can be selected; when the oil and suspended matters in the water are high, walnut shells, quartz sand and other filter materials can be selected to meet the water outlet requirement.
When the fluctuation of the inflow water is large, especially when the actual treatment capacity is less than the designed treatment capacity, the wastewater entering the rotational flow air flotation reactor cannot reach the flow rate required by the rotational flow or the amount of flocs in the effluent of the reactor is large, the buffer area has the functions of reducing the flow rate of the water body and increasing the settling time of the water body, and the outlet water quality of the system is still ensured by the principle of a shallow pool behind an inclined plate (pipe).
In the field operation process, the installation position of the rotational flow air flotation system in the whole process can be flexibly selected, and the property of the filler can be determined. When the composite material is used as a pretreatment device of a water treatment system, an inclined plate (pipe) or a coarse grained material can be selected to correspond to high-oil-content produced water and fracturing flow-back fluid, so that the rear-end load is reduced. When the filter material is used as a fine treatment device of a water treatment system, the walnut shell, the modified fiber balls, the quartz sand, the active filter material and other filter materials can be selected to correspond to the water quality of high suspended matters, so that the concentration of suspended matters in the water quality and the median of the particle size are reduced. The coarse grained material is an oleophilic material, the relative density is more than 1, and the grain size is preferably 3-5 mm, such as ceramsite and the like.
