Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solution mixing, in particular to a water treatment mixing cyclone structure and system. Background Art
[0002] During oil and gas production, condensate oil and gas field water form a mixture and flow out of the wellhead. The gas dissolved in the mixture will precipitate and expand, causing violent stirring of the oil and water, resulting in emulsification of produced water from the oil and gas fields. The emulsification of oil and water directly leads to the difficulty in removing suspended matter and petroleum substances. The emulsification of produced water from oil and gas fields is due to the directional adsorption of emulsified molecules on the oil-water interface to form a solid interface film (colloid). The hydrolysis form is mainly monomers and complex ions with low polymerization degree and high charge. At this time, the flocculation effect is mainly manifested in the emulsification of The compression effect of the double electric layer at the oil-water interface in the chemical wastewater hinders the conditions for the mutual aggregation and destabilization of the oil droplets. The wastewater is turbid and milky, resulting in a significant reduction in flocculation capacity. Under the influence of the emulsified colloid, the fine suspended matter in the water body cannot be effectively flocculated, which effectively reduces the floccules, charge neutralization and adsorption bridging effects in the wastewater, making it impossible to remove the fine suspended matter in the water body. At the same time, the effective thickness of the double electric layer is increased, and the width and steepness of the potential distribution of the double electric layer are increased, so that the oil is evenly dispersed in the water. Therefore, the emulsified oil droplets can stably exist in the water and are not easy to remove, which is the main reason for the unsatisfactory treatment effect of suspended matter, suspended solids and petroleum.
[0003] The inventors found that the traditional method uses non-invasive mixing of reagents, such as flocculation pipes or stirring blades. Each method attempts to open the flocculant in the wastewater and prevent it from agglomerating. However, both methods are not very effective because it is difficult for them to fully stretch the skeleton of the flocculant monomer, so it is difficult to meet the problems that need to be solved in oil and gas field production and treatment.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0026] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] This embodiment provides a water treatment mixed cyclone structure, which is mainly used to solve the problem that it is difficult to open the flocculant in wastewater in the prior art. The specific solution is as follows:
[0029] like Figure 1 As shown, the present embodiment provides a water treatment mixing cyclone structure, including a mixer barrel 10, a first mixing section 20, a second mixing section 30, a third mixing section 40 and a fourth mixing section 50; the first mixing section 20, the second mixing section 30, the third mixing section 40 and the fourth mixing section 50 are sequentially arranged inside the mixer barrel 10, the first mixing section 20 includes a positive rotation blade and a reverse rotation blade, and the positive rotation blade and the reverse rotation blade are cross-arranged inside the mixer barrel 10, the second mixing section 30 includes a double-channel spiral blade 31, and the double-channel spiral blade 31 is arranged inside the mixer barrel 10, the third mixing section 40 includes a single-channel spiral blade 41, and the single-channel spiral blade 41 is arranged inside the mixer barrel 10, and the fourth mixing section 50 includes a Z-shaped cyclone blade 51, and the Z-shaped cyclone blade 51 is arranged inside the mixer barrel 10.
[0030] It is understandable that the above four mixing sections can effectively increase the demulsification reaction speed, stretch the flocculant, and lengthen the silk chain of the water treatment agent, but do not cut them off; due to the 100% contact between the agent and the pollutant, it not only reduces the agent consumption, but also greatly increases the floc density and reduces the sludge water content. It can destroy the emulsified liquid structure, mix and produce chemical reactions with different swirl degrees, and improve the treatment function and efficacy of each treatment agent.
[0031] In detail, in the first mixing section 20, the function of the positive rotation blade and the reverse rotation blade is to separate the mixed solution of produced water and reagent. A part of the produced water generates a positive rotation after passing through the positive rotation blade, and the other part of the produced water generates a reverse rotation after passing through the reverse rotation blade. Then, at the tail end of the positive rotation blade and the reverse rotation blade, the two parts of the produced water collide so that the overall produced water and reagent are mixed more fully, so that the reagent can be fully opened.
[0032] In detail, in the second mixing section 30 and the third mixing section 40, the double-hole spiral blades 31 and the single-hole spiral blades 41 enable the mixed water to push the central liquid flow toward the periphery and push the peripheral fluid toward the center when passing through, thereby achieving better mixing.
[0033] In detail, in the fourth mixing section 50, the Z-shaped swirl blades 51 can change the direction of the mixed water for multiple times, reorganize it, and collide it multiple times on the Z-shaped swirl blades 51 to achieve further mixing.
[0034] Furthermore, according to the reaction time of different reagents, the present embodiment utilizes the first mixing section 20, the second mixing section 30, the third mixing section 40 and the fourth mixing section 50 to make the fluid rotate from time to time to the left and from time to time to the right, and constantly change the flow direction. Through multiple swirl collisions, the mutually incompatible fluids produce "rotation", "cutting", "displacement", "crushing" and "overlapping" movements in the pipeline, undergo multiple segmentation, shearing, rotation and re-merger, and constantly push the central liquid flow to the periphery, and push the peripheral fluid to the center, thereby creating a good radial mixing effect, so that the produced water and the reagent are fully mixed. This process greatly shortens the mixing reaction time of the reagent and the produced water, uses centrifugal force to stretch the water treatment reagents, and does not cut them off, stretching the silk chain of the water treatment reagents, so that the reagents are fully utilized, reducing the dosage of the reagents, and saving production and operation costs.
[0035] It is worth noting that the present embodiment is not limited to only four mixing segments, but may also be any other number of mixing segments. Any number of mixing segments that are recombined and arranged using the four mixing segments in the present embodiment are within the protection scope of the present embodiment.
[0036] In a preferred embodiment, a plurality of positive rotation blades and a plurality of reverse rotation blades are provided in the first mixing section 20, a single positive rotation blade and a single reverse rotation blade are cross-connected to form an X-shaped swirl blade 21, a plurality of positive rotation blades and a plurality of reverse rotation blades form a plurality of X-shaped swirl blades 21, and the plurality of X-shaped swirl blades 21 are arranged inside the mixer barrel 10 along the length direction of the mixer barrel 10.
[0037] In detail, the multiple X-shaped swirl sheets 21 in this embodiment are connected together and connected to the inside of the mixer barrel 10 by welding or bonding. In addition, since too small a number will affect the mixing, and too large a number will affect the speed of the fluid, the specific number depends on the situation.
[0038] Furthermore, the present embodiment does not limit the shape of the positive-rotation blade and the counter-rotation blade after being connected to an X shape, but may also be any shape, and any shape having the effect of the present embodiment is within the protection scope of the present embodiment.
[0039] In a preferred embodiment, the second mixing section 30 includes at least two double-channel spiral blades 31 , the two double-channel spiral blades 31 are arranged inside the mixer barrel 10 at intervals, and the single-channel spiral blade 41 is arranged between the two double-channel spiral blades 31 .
[0040] It can be understood that a single-channel spiral blade 41 is arranged between two double-channel spiral blades 31 so that the mixed liquid can undergo two mixing type conversions when passing through, the first time from the double-channel spiral blade 31 to the single-channel spiral blade 41, and the second time from the single-channel spiral blade 41 to the double-channel spiral blade 31. The two mixing type conversions make it easy to mix fully, so that the reagent and the produced water can be fully mixed and reacted.
[0041] In a preferred embodiment, the fourth mixing section 50 includes a plurality of Z-shaped swirl blades 51, which are combined to form a mesh structure and are arranged inside the mixer barrel 10. In detail, the specific shape of the Z-shaped swirl blades 51 in this embodiment is a wave shape.
[0042] It can be understood that the present embodiment does not limit the structure formed by the combination of the multiple Z-shaped swirl sheets 51 to only a mesh structure, and the multiple Z-shaped swirl sheets 51 can also be combined into other shapes.
[0043] In a preferred embodiment, the end of the mixer barrel 10 close to the first mixing section 20 is the water inlet 11, and the end close to the fourth mixing section 50 is the water outlet 12. The shape of the water inlet 11 is conical, and the top of the cone is away from the first mixing section 20. The shape of the water outlet 12 is also conical, and the top of the cone is away from the fourth mixing section 50.
[0044] It can be understood that the conical structure is also conducive to the mixing of produced water and reagents. The principle is that when the liquid enters from the smaller end face of the cone and comes out from the larger end face, there is a pressure release process in this process, and the pressure release process is conducive to the mixing of the solution. On the other hand, if the liquid enters from the larger end face of the cone and comes out from the smaller end face, there is also a change in pressure, and the pressure changes from small to large. This process is also conducive to the mixing of the solution.
[0045] In a preferred embodiment, flanges 60 are provided on both the water inlet 11 and the water outlet 12. It can be understood that the purpose of providing the flanges 60 is to facilitate the connection between pipes.
[0046] In a preferred embodiment, the water treatment mixing cyclone structure further includes a feeding device 70 , which is connected to the mixer cylinder 10 and is located between the water inlet 11 and the first mixing section 20 .
[0047] It should be noted that the setting position of the feeding device 70 in this embodiment is not fixed. The optimal position is located between the water inlet 11 and the first mixing section 20 as described in this embodiment, so that the produced water and the reagent can be mixed multiple times.
[0048] In a preferred embodiment, the mixer barrel 10 is made of stainless steel; the first mixing section 20, the second mixing section 30, the third mixing section 40 and the fourth mixing section 50 are all made of stainless steel.
[0049] The water treatment mixing cyclone structure provided in this embodiment has the following advantages:
[0050] The water treatment mixing cyclone structure provided in this embodiment makes the mixing speed of produced water and reagents fast, the residence time short, the dosage of reagents small, the reaction thorough, and the treatment effect remarkable, greatly improving the floc density and reducing the sludge water content; it can destroy the emulsified liquid structure, mix and produce chemical reactions with different cyclone degrees, and improve the treatment function and efficacy of each treatment reagent. This process greatly shortens the mixing reaction time of the reagent and produced water, stretches the water treatment reagents without cutting them, and lengthens the silk chain of the water treatment reagents, so that the reagents are fully utilized, reducing the dosage of the reagents and saving production and operation costs.
[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
