For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1As shown, this embodiment provides an unpowered mixed reaction separation device, including: a main body 1, for example, the main body 1 can be a vertical tank-shaped structure, and a conical bottom mud bucket 13 is arranged at the bottom of the main body 1; a central lifting area 2, located in the main body 1 and above the mud bucket 13, a gap is left between the central lifting area 2 and the bucket wall of the mud bucket 13 to form a return water port 3, and the water inlet of the central lifting area 2 is connected to an external sewage source. For example, the central lifting area 2 can be formed by installing a central riser 20 in the main body 1, and the bottom of the central riser 20 at least partially extends into the mud bucket 13. Since the middle diameter of the central riser 20 is smaller than the diameter at the water inlet, the fluid will be accelerated, so that the Bernoulli principle can be used to effectively regulate the channel water body. a continuous upward power; a hydraulic mixing zone, located in the main body 1 and arranged along the circumference of the central lifting zone 2, the hydraulic mixing zone includes a first annular channel 4, an ascending channel 5, an inner ring descending zone 6 and a second annular channel 7 arranged in sequence along the flow path of the water body; the water inlet of the first annular channel 4 is connected to the water outlet of the central lifting zone 2, and the second annular channel 7 converges with the first annular channel 4 at the entrance of the ascending channel 5; an annular water collection zone 8, located in the main body 1 and arranged along the circumference of the central lifting zone 2, the water outlet of the annular water collection zone 8 is connected to the outside of the main body 1; the water outlet of the inner ring descending zone 6 is divided into a first branch and a second branch, the first branch is connected to the water inlet of the annular water collection zone 8, and the second branch is connected to the water inlet of the second annular channel 7. The water flowing out through the outlet of the central lifting area 2 enters the first annular channel 4, flows out through the first annular channel 4, enters the ascending channel 5, ascends, and further enters the inner ring descending area 6 to descend, and further flows out through the outlet of the inner ring descending area 6 to form the first branch and the second branch, and the water flowing out through the second branch enters the second annular channel 7, and further merges with the water flowing out of the first annular channel 4 and enters the ascending channel 5. For example, the formation of the hydraulic mixing zone can be achieved by installing a mixing and stirring internal part in the main body 1, wherein the mixing and stirring internal part can be composed of two annular plates 18, wherein the two annular plates 18 are both arranged along the circumference of the central ascending pipe 20, the area between the inner annular plate 18 and the central ascending pipe 20 is used to form the ascending channel 5, and the area between the two annular plates 18 is used to form the inner ring descending area 6. It should be noted that the inner annular plate 18 refers to the annular plate 18 that is closer to the center line of the central ascending pipe 20. The formation of the first annular channel 4 and the second annular channel 7 will be described in detail below. One end of the mud discharge pipe 14 is connected to the mud discharge bucket 13, and the other end extends out of the main body 1. When water enters, the sewage rises along the central riser 20, and the heavy mud and sand particles fall into the mud discharge bucket 13 and are discharged out of the main body 1 through the mud discharge pipe 14.With this arrangement, the sediment particles in the sewage can be separated in advance before the sewage is mixed and stirred, thereby reducing the subsequent processing load.

[0026] The unpowered mixing reaction separation device provided in this embodiment has a hydraulic mixing zone set between the central lifting zone 2 and the annular water receiving zone 8 along the flow path of the water body, so that the water body is repeatedly circulated at high speed in the two channels of the ascending channel 5 and the inner ring descending zone 6 in the hydraulic mixing zone, so that the collision between sewage and the reagent is more frequent, which is conducive to improving the mixing effect and laying a good foundation for the flocculation and sedimentation separation in the later stage. Compared with the mixer using mechanical stirring, there is no need to set up additional stirring components such as water pumps and rotating motors, the structure is simpler, and energy consumption can be reduced.

[0027] Among them, a number of guide plates 9 are arranged in an interlaced manner along the fluid direction of the water body in the inner ring downward zone 6. For example, the guide plates 9 can be installed on the inner wall of the outer annular plate 18 and the outer wall of the inner annular plate 18, and each guide plate 9 can be arranged in the horizontal direction, and the area of ​​the guide plate 9 is smaller than the water outlet surface area of ​​the inner ring downward zone 6. In this way, when the water body in the inner ring downward zone 6 moves downward, it will collide with the guide plates 9, change speed and other turbulent effects, so that the collision between sewage and medicine is more frequent, which is conducive to improving the mixing effect.

[0028] Among them, the water outlet of the inner ring downward zone 6 is provided with a reflecting plate 10 to guide the water body to flow toward the water inlet of the second annular channel 7, so that the water body changes from flowing downward to flowing upward. For example, at the water outlet position of the inner ring downward zone 6, the end of the inner ring plate 18 can be provided with a folded edge inclined toward the direction of the outer ring plate 18, so that the diameter of the water outlet of the inner ring downward zone 6 is reduced, which can have an acceleration effect on the water body after the water is discharged. For example, the reflecting plate 10 can be installed on the outer ring plate 18, and the direction of the reflecting plate 10 can be parallel to the folded edge at the end of the inner ring plate 18, so as to better guide the water body obliquely upward into the second annular channel 7.

[0029] Among them, the unpowered mixed reaction separation device also includes an external descending zone 11 and a diversion zone 12; the external descending zone 11 is located in the main body 1 and is arranged along the circumference of the hydraulic mixing zone, and the water inlet of the external descending zone 11 is connected with the water outlet of the central lifting zone 2; the diversion zone 12 is located in the main body 1 and is arranged along the circumference of the hydraulic mixing zone, and the water inlet of the diversion zone 12 is connected with the water outlet of the external descending zone 11; the water outlet of the diversion zone 12 is divided into a third branch and a fourth branch, the third branch is connected with the water inlet of the first annular channel 4, and the fourth branch is connected with the return water port 3. For example, the formation of the diversion area 12 can be achieved by installing a guide cover 19 in the main body 1. The guide cover 19 can be an inverted cone structure as a whole. The small end of the guide cover 19 faces upward and is sleeved on the outer periphery of the central riser 20. The small end of the guide cover 19 can be provided with an extension section parallel to the central riser 20. The area between the extension section of the small end of the guide cover 19 and the central riser 20 can form the first annular channel 4. The area between the rest of the guide cover 19 and the central riser 20 forms the diversion area 12, and the water outlet surface of the diversion area 12 adapted to the water outlet of the first annular channel 4 can be gradually reduced, and the water body will be accelerated when entering the first annular channel 4 from the diversion area 12.

[0030] At the same time, the inner annular plate 18 and the folded edge at the end and the area between the deflector 19 and its extension form a second annular channel 7. At this time, the channel cross-sectional area of ​​the second annular channel 7 is gradually reduced along the direction of the water body, so that the water body can accelerate upward and merge with the water body from the first annular channel 4 and enter the ascending channel 5.

[0031] At the same time, the area between the deflector 19, the outer annular plate 18 and the inner wall of the main body 1 forms an external descending zone 11, and the water outlet surface of the external descending zone 11 gradually decreases at this time, which can also accelerate the water entering the diversion zone 12 from the external descending zone 11.

[0032] For example, an annular water collecting plate may be provided at the bottom of the outer annular plate 18 along the circumferential direction, and the space between the annular water collecting plate and the air guide cover 19 serves as the annular water collecting area 8 .

[0033] Among them, the gap between the bucket wall of the mud bucket 13 and the guide cover 19 is used to allow the water in the external downward area 11 to enter the guide diversion area 12. Under the guidance of the bucket wall of the mud bucket 13, a part of the water in the diversion area 12 is guided to flow back to the central lifting area 2.

[0034] Among them, the unpowered mixing reaction separation device also includes a nozzle 15 and a water inlet pipe 16; the nozzle 15 is arranged in the central lifting area 2; for example, the water outlet of the nozzle 15 is inserted into the central rising pipe 20, one end of the water inlet pipe 16 is connected to the nozzle 15, and the other end is suitable for connecting to the sewage source outside the main body 1, and the nozzle 15 accelerates the water body and sends it into the central lifting area 2.

[0035] Among them, water with several times the water inlet volume of the diversion area 12 in the present application flows back from the reflux port at the bottom of the central riser 20 due to the central drainage and mixes with the water at the outlet of the nozzle 15. Under the action of the water inlet push flow, water with the same water inlet volume rises and enters the first annular channel 4. In this process, the spatial cross-sectional area of ​​the diversion area 12 is large, and the amount of water rising into the first annular channel 4 is small, so the rising water will undergo sedimentation and separation, and the heavier particles will sink into the mud discharge bucket 13, further improving the separation effect of the mud and sand particles.

[0036] The unpowered mixed reaction separation device further includes an exhaust pipe 17, one end of which is connected to the intersection of the ascending channel 5 and the inner ring descending zone 6, and the other end is connected to the central lifting zone 2. For example, the top of the central ascending pipe 20 can be folded outward and connected to the top of the outer annular plate 18, and the water flowing out of the central lifting zone 2 can diffuse to the surroundings and pass over the top of the outer annular plate 18 to enter the outer descending zone 11. For example, the exhaust pipe 17 can be arranged on the inner wall of the central ascending pipe 20 in the horizontal direction, and the exhaust pipe 17 penetrates the pipe wall of the central ascending pipe 20. The gas carried by the water in the ascending channel 5 hitting the central ascending pipe 20 at the top can be discharged from the exhaust pipe 17 to the central lifting zone 2, preventing the internal air pressure of the ascending channel 5 from being too high, avoiding the water in the ascending channel 5 from being obstructed during the upward process, and facilitating the high-speed circulation of the water between the ascending channel 5 and the inner ring descending zone 6.

[0037] There are two ways of discharging water from the annular water collection area 8:

[0038] like Figure 1 As shown, in one embodiment, one end of the water outlet pipe 21 is connected to the annular water receiving area 8, and the other end extends upward to the top of the main body 1 through the external descending area 11 and passes through the outer edge of the top wall of the main body 1 to the outside of the main body 1, so as to discharge the water in the annular water receiving area 8. The number of the water outlet pipes 21 can be set as needed.

[0039] like Figure 2 As shown, in another embodiment, one end of the water outlet pipe 21 is connected to the annular water collecting area 8, and the other end passes through the outer edge of the side wall of the main body 1 to the outside of the main body 1 for discharging the water in the annular water collecting area 8.

[0040] When in use: water enters from the water inlet pipe 16 and is released from the nozzle 15 at an accelerated speed. At the same time, under the action of the Bernoulli principle, the refluxed water enters the central lifting area 2 together with the water in the nozzle 15, is released at the top of the central lifting area 2 through the enlarged opening, and then enters the external descending area 11. When the water descends to the bottom, the guide cover 19 disperses the water to the surroundings. Since the reflux is in the center, the deflection can extend the water's path and increase the residence time. In addition, the guide cover 19 changes the water flow section, plays a role in speed change, and enhances the mixing effect. The water flow section between the bucket wall of the mud bucket and the guide cover 19 becomes smaller, and the bucket wall of the mud bucket extends toward the return water port 3 of the central riser 20, which is conducive to the reflux guidance. Most of the water in the diversion area 12 enters the central riser due to the internal circulation, and the continuous water inflow pushes the rest of the water into the first annular channel 4. Since the cross-sectional area of ​​the first annular channel 4 is reduced, the flow rate of the water increases after it is released upward. Under the action of the Bernoulli principle, the water in the second annular channel 7 will participate in the water inflow and enter the riser channel 5. Due to the increase in water volume, the flow rate increases, and the water flows over the top of the riser channel 5 and enters the inner ring descending area 6. When the water flows downward, the reflector 10 changes the direction of the water from downward to obliquely upward, which is beneficial to the drainage of the first annular channel 4. Due to the thrust of the inflow, the excess water will bypass the reflector 10 and enter the annular water collection area 8, and the water will be introduced into the downstream process section through the outlet pipe 21.

[0041] Another embodiment further provides a water treatment system, comprising any of the above-mentioned unpowered mixing reaction separation devices.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
