Description

Technical Field

[0001] The present invention relates to the technical field of phase separation, and in particular to a phase separation device and a phase separation method. Background Art

[0002] At present, phase separation problems exist in many fields, such as source water treatment and mud-water separation. Some of them are the separation of substances in different phases, and some are the separation of substances in the same phase dissolved in a matrix. The source water treatment problem is relatively serious at this stage. The source water in most areas is plagued by various problems such as algae problems and MIB problems. The methods of manual salvage and salvage ships, or the addition of additives such as activated carbon to the water, all have core problems such as incomplete solution of the problem and secondary pollution caused by residual substances. The existing technology can generally only treat slightly polluted water sources. It is not capable of radically solving the problem in areas where the problem is more serious, or there are problems such as high investment costs in solving the problem and low economic benefits.

[0003] Regarding sludge-water separation pretreatment, sludge treatment produces two resources: mud cake and water. The effluent water produced from the sludge meets Class A standards, comparable to landscape water quality. Furthermore, the sludge water output is substantial. For example, treating 100 million tons of sludge produces water equivalent to the volume of a medium-sized reservoir. Whether used as landscape water, industrial water, or further purified for domestic use, this represents a significant resource. Sludge treatment projects are particularly valuable in water-scarce regions, such as the northwest. Currently, the main sludge treatment methods include ultrasonic pretreatment, microwave pretreatment, and electrodialysis pretreatment. The effectiveness of ultrasonic pretreatment is influenced by ultrasound intensity, treatment time, and operating frequency. Its mechanism of action is complex, requiring optimized control parameters to achieve a balance between treatment efficiency and energy consumption, making precise control difficult. Microwave pretreatment pretreats sludge through volumetric heating. However, the release of high-molecular-weight organic polymers such as proteins, polysaccharides, and nucleic acids from sludge flocs during microwave pretreatment increases the sludge's specific resistance and viscosity, thereby reducing its filterability. Electrodialysis pretreatment is affected by factors such as electric field strength, solution pH, and electrode shape. Due to the different mechanisms of action of the cathode and anode during electrodialysis, there are drawbacks such as significant differences in resistivity and dehydration efficiency between the two electrodes. Consequently, this resource is currently underutilized.

[0004] It can be seen from this that the above-mentioned existing phase separation processing devices and methods still have inconveniences and defects, and are in urgent need of further improvement. How can we create a new phase separation device and phase separation method that can not only solve the problem of rapid separation of different phases in the matrix, but also realize the centralized collection of separated solid substances, as well as solve the problem of separation of the same phase in the matrix and centralized collection of additives, so as to avoid the problems of incomplete solutions and secondary pollution caused by existing technologies? Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a phase separation device that can not only solve the rapid separation of different phase substances in the matrix, but also realize the centralized collection of separated solid substances, as well as solve the separation of the same phase substances in the matrix and the centralized collection of additives, avoiding the problem that the existing technology does not solve the problem thoroughly and causes secondary pollution, and overcomes the shortcomings of the existing phase separation device.

[0006] In order to solve the above technical problems, the present invention provides a phase separation device, including a cylindrical filter and a spiral mechanism arranged inside the cylindrical filter. The front end of the cylindrical filter is open and the end is provided with a valve body. The spiral mechanism includes a rotating shaft and a spiral blade fixed thereon. The edge of the spiral blade forms an elastic interference fit with the inner wall of the cylindrical filter. The cylindrical filter and the spiral mechanism rotate relative to each other to achieve axial pressurization and radial centrifugation of the internal matrix of the cylindrical filter, thereby achieving the separation of different phase substances in the matrix, and the solid matter intercepted by the cylindrical filter is pushed by the spiral blade to gather toward the end of the cylindrical filter, and the valve port of the valve body is connected to a collection mechanism or a conveying mechanism.

[0007] As a further improvement, the cylindrical filter screen adopts a conical cylindrical filter screen, the diameter of which gradually decreases from its front end to the rear end, and the spiral blade adopts a conical spiral blade corresponding to the conical cylindrical filter screen.

[0008] As a further improvement, the spiral blade adopts a variable pitch setting with a large inclination angle at the front end and a small inclination angle at the rear end.

[0009] As a further improvement, a spindle-shaped structure is provided at the end of the rotating shaft, and the spiral blades are spirally arranged around the outer side wall of the spindle-shaped structure.

[0010] A further improvement includes a driving mechanism for driving the rotating shaft to rotate, and the rotating shaft drives the spiral blade to rotate relative to the cylindrical filter screen under the action of the driving mechanism.

[0011] As a further improvement, the valve body adopts a pressure control valve body, and the valve port of the pressure control valve body is connected to the conveying pipeline of the conveying mechanism, or is connected to the collecting port of the collecting mechanism.

[0012] As a further improvement, the edge of the spiral blade is elastically interference-fitted with the cylindrical filter screen via a rubber strip.

[0013] Further improvements include a homogeneous substance separation mechanism, which includes an additive delivery mechanism and an additive reaction mechanism. The additive reaction mechanism adopts an annular cylinder connected to the front end of the cylindrical filter. The additive delivery mechanism is arranged above the front end of the annular cylinder and is provided with multiple delivery outlets. The multiple delivery outlets deliver additives for adsorbing or precipitating homogeneous substances in the matrix into the interior of the annular cylinder in different directions.

[0014] Further improvement, it also includes a support mechanism for fixing the cylindrical filter screen, the support mechanism includes a support frame provided on the outer peripheral side of the cylindrical filter screen and a frame mechanism connected to the support frame;

[0015] The support frame is provided with an upper guide rail and a lower guide rail, the frame mechanism is provided with an upper guide rail groove and a lower guide rail groove that slide corresponding to the upper guide rail and the lower guide rail respectively, and the frame mechanism is also provided with a limiting mechanism for fixing the lower guide rail and the lower guide rail groove.

[0016] As another improvement of the present application, the present invention also provides a phase separation method, including a method for separating substances of different phases. The method for separating substances of different phases is to generate axial pressurization and radial centrifugation of the internal matrix of the cylindrical filter through the relative rotation of the cylindrical filter and the spiral mechanism arranged inside the cylindrical filter, so as to achieve the separation of substances of different phases in the internal matrix of the cylindrical filter, and to realize the pushing and collection of solid substances intercepted by the cylindrical filter through the elastic interference fit between the edge of the spiral blade in the spiral mechanism and the inner wall of the cylindrical filter.

[0017] As a further improvement, the spiral blades in the spiral mechanism adopt a variable pitch setting with a large inclination angle at the front end and a small inclination angle at the rear end.

[0018] Further improvements include a method for separating substances in the same phase, which comprises adding an additive for adsorbing or precipitating substances in the same phase in the matrix into the matrix, completing the adsorption or precipitation of the additive in the matrix, and then using the method for separating substances in different phases to separate and collect them.

[0019] As a further improvement, the additive is added to the matrix by using a plurality of delivery outlets with different delivery directions to enable rapid and thorough mixing of the additive and the matrix.

[0020] After adopting such a design, the present invention has at least the following advantages:

[0021] 1. The phase separation device of the present invention generates a vortex in the matrix inside the cylindrical filter and reaches a certain degree of rotation by arranging a relatively rotating cylindrical filter screen and a spiral mechanism arranged inside the cylindrical filter screen. Under the action of the spiral blades, a certain axial boost thrust and a certain radial centrifugal force are generated on the matrix inside the cylindrical filter screen, thereby achieving good separation of different phase substances in the matrix while ensuring that the flux of the matrix before and after passing through the separation device is consistent. In addition, by making the edge of the spiral blade elastically interfere with the inner wall of the filter screen and arranging a valve body at the end of the cylindrical filter screen, the structure of the spiral blade can be utilized to realize the transportation and collection of solid substances intercepted by the filter screen, thereby achieving the separation of different phase substances and the unified collection of solid substances.

[0022] 2. By setting the cylindrical filter into a conical structure and the spiral blades into a variable pitch structure, the large inclination angle and large radius at the front end of the blades can be used to achieve the effect of low-speed supercharging, and the small inclination angle and small radius at the end of the blades can be used to achieve the effect of radial centrifugation, thereby ensuring the smooth operation of the matrix and the good separation of different phase substances in the matrix.

[0023] 3. A spindle-shaped structure is provided at the end of the rotating shaft, and the uphill section of the spindle-shaped structure is used to provide an outward-diffusion radial force to the axially flowing matrix, thereby better ensuring the separation of different phase substances in the matrix. The downhill section of the spindle-shaped structure is also used to form a storage space for solid substances between the downhill section and the filter screen. Combined with the setting of the valve body, the solid substances can be compacted, which facilitates the collection of the collected solid substances by the collecting mechanism or the conveying mechanism.

[0024] 4. The pressure control valve body is set so that the valve body automatically opens when the compressed solid matter reaches a certain pressure, thereby realizing the automated centralized collection of the solid matter and avoiding excessive fluid content in the collected solid matter, which is not conducive to subsequent processing.

[0025] 5. A homogeneous substance separation mechanism is provided at the front end of the cylindrical filter screen. The addition of additives through the homogeneous substance separation mechanism can achieve adsorption or precipitation of homogeneous substances in the matrix, and can ensure that the additives that have completed adsorption or precipitation of homogeneous substances are separated in time to avoid secondary contamination of the additives.

[0026] 6. The additive delivery mechanism is provided with multiple delivery outlets, and the output directions of the multiple delivery outlets are different, which can ensure the violent relative movement of the additive and the substrate, achieve short-term, efficient, rapid and sufficient mixing, and fully separate the same-phase substances.

[0027] 7. The phase separation method of the present invention can not only realize the filter separation of different phase substances, but also realize the separation of the same phase substances through the adsorption or precipitation of additives, and timely realize the separation of additives through the separation method of different phase substances, thereby avoiding secondary pollution caused by additives.

[0037] Refer to the attached Figures 1 to 3 As shown, the phase separation device of this embodiment includes an outer cylinder 1, a support mechanism disposed within the outer cylinder 1, and an actuator supported and fixed by the support mechanism. The outer cylinder 1 is a cylindrical structure with two open ends, and is used to fix the actuator inside via the support mechanism, forming a phase treatment device with a regular appearance. One end of the outer cylinder 1 is the water inlet end, which is preferably oriented opposite to the flow direction of the base, and the other end is the water outlet end. The actuator is used to separate substances in different phases from substances in the same phase. The specific embodiment is as follows.

[0038] In this embodiment, the actuator comprises a cylindrical filter screen 2 and a spiral mechanism disposed within the cylindrical filter screen 2. The cylindrical filter screen 2 has an open front end and a valve body 7 at its distal end. The spiral mechanism comprises a rotating shaft 3 and a spiral blade 4 fixed thereto. The edge of the spiral blade 4 forms an elastic interference fit with the inner wall of the cylindrical filter screen 2 via a rubber strip 5, effectively cleaning the inner wall of the filter screen. The cylindrical filter screen 2 can be constructed using an intercepting mesh structure such as a woven mesh or a mat-type filter screen. The rubber strip 5 at its edge can also be made of other materials, as long as it forms an elastic interference fit with the cylindrical filter screen 2 and does not affect the normal operation of the spiral blade. A cross-mounted bracket 6 is disposed at the front end opening of the cylindrical filter screen 2. The valve port of the valve body 7 at the distal end is connected to a collection mechanism or conveying mechanism 9. The outer periphery of the cross-mounted bracket 6 and the valve body 7 serves to secure the filter screen 2, while the center of the cross-mounted bracket 6 and the valve body 7 serves to secure the rotating shaft 3. Of course, the cross-mounted bracket 6 can also be constructed using other structures, as long as it does not interfere with the passage of the substrate.

[0039] In this embodiment, a driving mechanism 19, such as a motor or hydraulic mechanism, is provided on the cross-mounted bracket 6 to drive the rotation of the rotating shaft 3, thereby driving the spiral blades 4 to rotate relative to the cylindrical filter screen 2. Of course, the driving mechanism can also be configured to drive the rotation of the cylindrical filter screen 2 relative to the spiral blades 4, so as to form an eddy current in the matrix of the cylindrical filter screen and achieve a certain degree of rotation to promote the separation of different phases in the matrix.

[0040] In a preferred embodiment, the cylindrical filter screen 2 is a tapered cylindrical filter screen, the diameter of which gradually decreases from the front end to the rear end. The spiral blade 4 is a tapered spiral blade that matches the tapered cylindrical filter screen. Similarly, the edge of the tapered spiral blade 4 forms an elastic interference fit with the inner wall of the tapered cylindrical filter screen 2.

[0041] In this way, the rotating shaft 3 drives the spiral blade 4 to rotate under the action of the driving mechanism 19. The rotating spiral blade 4 can provide axial boosting thrust and radial centrifugal force to the matrix inside the cylindrical filter 2, causing the matrix inside the cylindrical filter 2 to generate vortexes and reach a certain degree of rotation, thereby promoting the separation of liquid and solid substances in the matrix through the filter. The solid substances intercepted by the filter 2 are gathered toward the end of the filter 2 under the spiral push of the spiral blade 4. Due to the setting of the valve body 7, the solid substances are continuously gathered in the storage space formed by the valve body 7, the end of the rotating shaft and the filter. When the solid substances have accumulated to a certain amount, the valve body 7 is opened, and the compressed solid substances overflow from the valve port of the valve body 7 to the collection mechanism or conveying mechanism 9, thereby realizing the collection or transportation of the solid substances.

[0042] A more preferred embodiment is to refer to the attached Figure 4As shown, the spiral blade 4 adopts a variable pitch setting, and the pitch of the spiral blade 4 gradually decreases from the front end to the end of the rotating shaft 3, that is, the front end of the spiral blade 4 adopts a large inclination angle and a large radius setting, which can achieve a low-speed supercharging effect on the matrix. The supercharging energy can supplement the energy lost when the matrix passes through the filter, ensuring that the flux of the matrix is consistent before and after passing through the phase separation device, and will not cause blockage and accumulation; the end of the spiral blade 4 adopts a small inclination angle and a small radius setting, which can achieve a radial centrifugal effect on the matrix, ensuring the smooth operation of the matrix and the good separation of different phase substances in the matrix.

[0043] Furthermore, in this embodiment, a spindle-shaped structure 20 is provided at the end of the rotating shaft 3, and the spiral blade 4 is spirally arranged around the outer wall of the spindle-shaped structure 20. The spindle-shaped structure 20 includes an upslope section near the front end of the rotating shaft and a downslope section near the outer end. The present application utilizes the upslope section of the spindle-shaped structure to impart an outward radial force to the substrate in axial flow, thereby better guiding the flow of the substrate. The downslope section of the spindle-shaped structure is also utilized to facilitate the formation of a solid matter storage space between the downslope section and the filter screen. Combined with the arrangement of the valve body, this facilitates the compaction of the solid matter, facilitating the collection of the collected solid matter by the collection mechanism or the conveying mechanism.

[0044] Refer to the attached Figure 5 As shown, in this embodiment, the valve body 7 is a pressure-controlled valve body. The valve port of the pressure-controlled valve body is connected to the delivery pipeline of the delivery mechanism 9. The valve body's drive mechanism 8 is disposed externally. When the pressure applied to the pressure-controlled valve body exceeds a predetermined value, the drive mechanism 8 controls the valve 22 to open, thereby enabling the delivery and collection of solid matter. Of course, the valve body can also be opened and closed by a timer or manually controlled.

[0045] The phase separation device of this embodiment also includes a homogeneous material separation mechanism. Figures 6 to 8 As shown, the homogeneous substance separation mechanism includes an additive delivery mechanism 10 and an additive reaction mechanism. The additive reaction mechanism utilizes an annular cylinder 11 connected to the front end of the cylindrical filter 2. The additive delivery mechanism 10 is disposed above the front end of the annular cylinder 11 and is provided with multiple delivery outlets 21. These delivery outlets 21 deliver additives into the annular cylinder 11 in different directions, allowing the additive to undergo vigorous relative motion with the substrate within the annular cylinder 11, achieving rapid and thorough mixing of the additive and the substrate. This allows the additive to adsorb or precipitate homogeneous substances dissolved in the substrate, ultimately achieving separation of the homogeneous substances dissolved in the substrate.

[0046] And because when the additive enters the annular cylinder 11, under the stable operation of the spiral blade 4, the additive enters the cylindrical filter 2 together with the matrix, further realizing the adsorption or precipitation of the dissolved substances in the matrix. At the same time, the additive that has completed the adsorption or precipitation of the dissolved substances is intercepted by the filter 2 as a solid substance in the matrix, and is gathered in the storage space under the drive of the spiral blade 4, and is finally transported and collected by the collection mechanism or the conveying mechanism 9.

[0047] In addition, the phase separation device also includes a support mechanism 18 for fixing the cylindrical filter 2. The support mechanism 18 includes a support frame 15 arranged on the outer peripheral side of the cylindrical filter 2 and a frame mechanism 18 connected to the support frame 15. Specifically, the support frame 15 is provided with an upper guide rail 16 and a lower guide rail 17, and the frame mechanism 8 is provided with an upper guide rail groove 12 and a lower guide rail groove 13 that slide corresponding to the upper guide rail 16 and the lower guide rail 17 respectively, and the frame mechanism 18 is also provided with a limiting mechanism 14 for fixing the lower guide rail 17 and the lower guide rail groove 13. In this embodiment, the limiting mechanism 14 uses a cylindrical bayonet to ensure that the support member 15 is firmly set on the frame mechanism 18.

[0048] When treating source water, the phase separation device is installed with the water inlet end of the outer cylinder 1 facing in the opposite direction of the source water matrix flow. Then, the drive mechanism 19 is activated, which drives the spiral blades 4 to rotate. The spiral blades 4 can provide axial pressure and radial centrifugal force to the matrix entering the cylindrical filter 2, so that the water-insoluble algae in the matrix are intercepted by the filter 2. At the same time, a suitable additive that can absorb substances such as 2-MIB and GSM in the source water is selected and added to the annular cylinder 11 through the additive delivery mechanism 10. The additive is fully mixed with the matrix, completing the adsorption or precipitation of the same phase substances dissolved in the matrix, such as 2-MIB and GSM. The adsorbed additive is then intercepted as solid matter in the matrix by the filter 2. The solid matter intercepted by the cylindrical filter 2 is all accumulated at the end of the filter under the push of the spiral blades 4. After reaching a certain accumulated amount, the valve body opens, realizing the centralized collection of algae and additives in the source water, thereby achieving the treatment of multi-phase substances in the source water.

[0049] The phase separation method implemented by the phase separation device of the present invention can not only utilize the relative rotation of the cylindrical filter and the spiral mechanism to achieve the separation of different phase substances, but also utilize the additive to adsorb or precipitate the same phase substances dissolved in the matrix to achieve the separation of the same phase substances, and timely recover the additives, thereby effectively avoiding secondary pollution caused by the additives and achieving the purpose of separating multi-phase substances.

[0050] The phase separation device and phase separation method can be used in multiple fields such as source water treatment, mud-water separation, and crude oil treatment, greatly saving manual labor time and preventing the risk of secondary pollution caused by additives.
