Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an anaerobic three-phase separator that improves solid-liquid-gas efficiency. Background Technology

[0002] Generally speaking, the anaerobic three-phase separator is the core equipment in the anaerobic wastewater treatment system used to complete the separation of sludge, wastewater and biogas into three phases. In the process of anaerobic wastewater treatment, it is necessary to rely on the internal structure of the equipment to achieve the degassing and separation of sludge with gas, the recycling and retention of sludge, the clarification and discharge of clean water and the centralized collection of biogas. In the anaerobic wastewater treatment operation, the three-phase separation effect of gas, sludge and water is the core indicator that determines the wastewater quality, biogas yield and sludge system stability. However, traditional anaerobic three-phase separators have many inherent defects in actual operation. The internal flow channel structure of traditional equipment is simple, and the sludge fluid containing air bubbles mostly rises in a concentrated, direct stream, resulting in chaotic fluid flow. This makes it impossible to evenly distribute and guide the sludge fluid, making it difficult to fully remove the tiny air bubbles covering the sludge surface. A large number of sludge flocs continue to carry air bubbles and cannot settle, easily causing sludge to be lost with the effluent, leading to insufficient sludge concentration in the reaction zone, a decrease in the number of microorganisms, and a significant reduction in wastewater degradation efficiency. It also results in incomplete biogas release and collection, leading to low biogas production efficiency. Furthermore, traditional three-phase separators... The traditional anaerobic three-phase separator has poor three-phase separation and stratification effects. Some incompletely degassed fine flocs are easily carried into the clear water area by the water flow, causing turbid water and substandard water quality. In addition, traditional equipment lacks a complete sludge return and impurity removal structure. The degassed and settled sludge does not fall smoothly, which can easily lead to local sludge accumulation and flow channel blockage. The aged flocs and light flocculated impurities produced by the reaction cannot be discharged in time. Long-term accumulation will pollute the activated sludge and inhibit microbial activity. Based on this, the present invention aims to provide an anaerobic three-phase separator with optimized structure, good degassed effect, stable sludge circulation, and improved solid-liquid-gas three-phase separation efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an anaerobic three-phase separator that improves solid-liquid-gas efficiency, thereby solving the technical problems in the prior art.

[0004] The objective of this invention can be achieved through the following technical solutions: An anaerobic three-phase separator for improving solid-liquid-gas efficiency includes: A separation tank has two symmetrically arranged baffles fixedly installed inside. Each baffle has an inclined guide plate fixedly installed at its top. The distance between the two guide plates increases downwards along the central axis of the separation tank. A V-shaped plate is fixedly installed inside the separation tank, located below the liquid level. A water storage cavity is formed between the V-shaped plate and the top of the separation tank. The bottom of the V-shaped plate is located between the two guide plates, and the top of the V-shaped plate is located above the guide plates. A separation port is formed between the top of the guide plate and the inclined surface of the V-shaped plate. A mixing cavity is formed between one side of the baffle and guide plate and the other side of the baffle and guide plate. The mixing chamber is connected to the water storage chamber through the separation port. The mixing chamber is filled with anaerobic sludge. A water injection pipe is installed through the separation tank. The output end of the water injection pipe is located in the anaerobic sludge. A drain pipe is installed on the separation tank and is connected to the water storage chamber. Two symmetrically arranged vent pipes are connected to the top of the separation tank. Multiple staggered protrusions are provided on both the two guide plates and the V-shaped plate. Multiple protrusions are located in the mixing chamber. Multiple flow guide grooves are opened on the opposite side of the two guide plates and on the inclined surface of the V-shaped plate. A protrusion is fixedly installed in each flow guide groove. A protrusion is provided between two adjacent flow guide grooves.

[0005] As a further aspect of the present invention: two symmetrically arranged rhomboid dividing blocks are provided in the mixing chamber. Both rhomboid dividing blocks are fixedly installed on the inner wall of the separation tank. The two rhomboid dividing blocks are located on both sides of the V-shaped plate, and the rhomboid dividing blocks are located between the guide plate and the V-shaped plate.

[0006] As a further aspect of the present invention: there is a reflux slit between each of the partitions and the inner wall of the separation tank, there is a communication port between the bottom end of the partition and the bottom plate of the separation tank, the reflux slit is connected to the bottom end of the mixing chamber through the communication port, the top end of the mixing chamber is connected to the reflux slit through the separation port, and the water storage chamber is connected to the reflux slit.

[0007] As a further embodiment of the present invention: two symmetrically arranged inclined baffles are fixedly installed on the inner wall of the separation tank. The inclined baffles are located above the guide plate and are arranged in parallel. The higher horizontal end of the inclined baffle is fixedly connected to the inclined surface of the V-shaped plate. A vent hole is provided at the connection between the inclined baffle and the V-shaped plate.

[0008] As a further aspect of the present invention: the bottom end of the separation tank is connected to a sludge discharge pipe, and a valve is provided on the sludge discharge pipe.

[0009] As a further aspect of the present invention: two symmetrically arranged rotating plates are rotatably installed on the inner wall of the separation tank. The rotating plates are driven to rotate by a first driving source fixedly installed on the back of the separation tank. When the first driving source drives the rotating plates to rotate to abut the inclined baffle, the water storage cavity and the reflux slit are disconnected.

[0010] As a further aspect of the present invention: a waste discharge pipe is provided on both sides of the separation tank, and the two waste discharge pipes are respectively connected to two reflux slits.

[0011] As a further aspect of the present invention: a first filter plate is provided in the water storage cavity, the first filter plate is fixedly installed on the inner wall of the separation tank, and the first filter plate is also fixedly installed on the inner wall of the V-shaped plate. The drain pipe is located below the first filter plate. The water storage cavity is connected to the cleaning pipe, and the cleaning pipe is located above the first filter plate. Two symmetrically arranged second filter plates are rotatably installed in the water storage cavity. The second filter plates are driven to rotate by a second drive source fixedly installed on the back of the separation tank. The second filter plates are located above the V-shaped plate, and the top of the second filter plates is located above the liquid level in the separation tank. The bottom of the second filter plates is connected to the top of the V-shaped plate.

[0012] The beneficial effects of this invention are: 1. In this invention, a fluid distribution and guiding structure is formed by a V-shaped plate and a guide plate. A diamond-shaped dividing block is set between the guide plate and the V-shaped plate. The rising sludge fluid with bubbles will first collide with the diamond-shaped dividing block before reaching the separation port. The gathered fluid is evenly divided into two independent fluids by the diamond-shaped dividing block. The two fluids flow towards the surfaces of the guide plate and the V-shaped plate respectively, which disperses the fluid velocity, balances the degassing force, and avoids the residual sludge bubbles caused by concentrated fluid flushing. This allows the sludge fluid to evenly adhere to the plate surface structure. Then, a multi-stage impact shear degassing system is formed by the flow channel and staggered protrusions. Layered forced degassing is achieved through channel directional sliding and multi-point staggered impact. The micro bubbles inside the sludge flocs are actively peeled off, avoiding the problem of a large number of degassing dead zones in traditional three-phase separators that rely on natural static degassing. This comprehensively improves the gas-liquid separation efficiency and three-phase separation uniformity, and effectively increases the biogas output and collection utilization rate. 2. In this invention, a closed-loop sludge return structure is formed by the return seam formed by the partition and the inner wall of the separation tank and the bottom connection port. The thrust of the rising sludge and the negative pressure suction formed by the water injection pipe are used to actively draw back the incompletely degassed sludge to the reaction area of ​​the mixing chamber, so as to continuously stabilize the anaerobic sludge concentration in the chamber. Combined with the sludge interception and return structure of the inclined baffle and the gravity settling degassing mechanism, the problems of sludge loss, insufficient bacteria and sludge overflow are effectively avoided, ensuring the continuous and stable anaerobic reaction of sewage treatment, and greatly improving the equipment operation stability and sewage treatment effect. 3. In this invention, the controllable opening and closing of the water storage chamber and the return slit is achieved through a rotatable rotating plate. This allows for maintenance operations such as replacing aged sludge and cleaning internal impurities without emptying the entire water body of the equipment. This saves water and simplifies the maintenance process. In addition, the double-layer filter plate structure in the water storage chamber and the rotatable second filter plate can break down residual flocculent microbubbles and intercept fine floating scum impurities. Combined with the directional impurity removal structure of the waste discharge pipe and cleaning pipe, the internal impurities of the equipment can be cleaned in layers, continuously ensuring the activity of the sludge.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-6 As shown, the present invention is an anaerobic three-phase separator for improving solid-liquid-gas efficiency, comprising: A separation tank 1 has two symmetrically arranged partitions 2 fixedly installed inside. Each partition 2 has an inclined guide plate 3 fixedly installed at its top. The distance between the two guide plates 3 increases downwards along the central axis of the separation tank 1. A V-shaped plate 4 is fixedly installed inside the separation tank 1, located below the liquid level. A water storage cavity 105 is formed between the V-shaped plate 4 and the top of the separation tank 1. The bottom of the V-shaped plate 4 is located between the two guide plates 3, and the top of the V-shaped plate 4 is located above the guide plates 3. A separation port 102 is formed between the top of the guide plate 3 and the inclined surface of the V-shaped plate 4. A mixing cavity 101 is formed between one side of the partitions 2 and guide plates 3 and the other side of the partitions 2 and guide plates 3. The mixing cavity 101 is open to... The separation port 102 is connected to the water storage chamber 105. The mixing chamber 101 is filled with anaerobic sludge. A water injection pipe 5 is installed through the separation tank 1. The output end of the water injection pipe 5 is located in the anaerobic sludge. A drain pipe 6 is installed on the separation tank 1. The drain pipe 6 is connected to the water storage chamber 105. Two symmetrically arranged exhaust pipes 7 are connected to the top of the separation tank 1. Multiple staggered protrusions 10 are provided on the two guide plates 3 and the V-shaped plate 4. The multiple protrusions 10 are all located in the mixing chamber 101. Multiple flow channels 11 are opened on the opposite side of the two guide plates 3 and the inclined surface of the V-shaped plate 4. A protrusion 10 is fixedly installed in each flow channel 11. A protrusion 10 is provided between two adjacent flow channels 11.

[0018] The working principle of this invention is as follows: Anaerobic sludge is filled inside the mixing chamber 101. Wastewater is continuously injected into the anaerobic sludge inside the mixing chamber 101 through the water injection pipe 5. The wastewater flow lifts the sludge, forming a stable suspended reaction zone. The wastewater and anaerobic sludge fully contact and react to generate biogas. This causes the sludge flocs, carrying air bubbles, to flow upwards with the water flow. During the upward movement of the sludge carrying air bubbles, it first contacts the bottom of the V-shaped plate 4, is evenly divided into two fluid streams, and slides upwards along the inclined surface of the V-shaped plate 4. Simultaneously, the guide plates 3 on both sides gather the scattered sludge fluid from the edges towards the central axis, solving the problems of uneven fluid distribution, excessively high local flow velocity, and numerous degassing dead zones in traditional equipment. As the fluid climbs along the inclined surfaces of the V-shaped plate 4 and the guide plate 3, a portion of the sludge slides slowly along the channel and repeatedly impacts the protrusions 10 inside the channel, achieving continuous shearing, squeezing, and oscillating degassing, forcibly stripping away the tiny bubbles wrapped inside the flocs. Another portion of the sludge flowing along the wall completes secondary impact degassing under the obstruction of the staggered protrusions 10 between adjacent guide channels 11. The staggered multi-point protrusion layout forms a fully covered turbulent degassing area. Compared with the defects of traditional single flat smooth structures that have no degassing effect, it achieves multi-stage active degassing without dead angles, greatly improving the thoroughness of bubble removal. After degassing through the separator 102, the biogas floats upward and converges, eventually being collected through the exhaust pipe 7 at the top of the separator 1, effectively improving the biogas recovery and utilization rate. The degassed sludge flocs lose the buoyancy support of the bubbles and fall back into the mixing chamber 101 under their own gravity to participate in the reaction, avoiding the problem of sludge loss. The degassed and purified water continuously rises in level. When the water level exceeds the top of the V-shaped plate 4, it automatically flows into the water storage chamber 105 based on the principle of communicating vessels. The high-level water has low impurity content and clear water quality, and is finally discharged stably through the drain pipe 6, completely completing the efficient separation of gas, solid and liquid phases.

[0019] like Figures 1-3 As shown, in a preferred embodiment of the present invention, two symmetrically arranged rhomboid dividing blocks 9 are provided in the mixing chamber 101. Both rhomboid dividing blocks 9 are fixedly installed on the inner wall of the separation tank 1. The two rhomboid dividing blocks 9 are located on both sides of the V-shaped plate 4, and the rhomboid dividing blocks 9 are located between the guide plate 3 and the V-shaped plate 4.

[0020] In practical application, the rising sludge fluid with bubbles will first collide with the diamond-shaped dividing block 9 before reaching the separation port 102. The gathered fluid is evenly divided into two independent fluids by the diamond-shaped dividing block 9. The two fluids flow towards the surfaces of the guide plate 3 and the V-shaped plate 4 respectively, so that the sludge fluid can evenly conform to the protrusions 10 and the guide groove 11 on the plate surface to complete the degassing operation, disperse the fluid flow rate, balance the degassing force, avoid the residual sludge bubbles caused by concentrated fluid flushing, and further improve the overall degassing efficiency and the uniformity of three-phase separation.

[0021] like Figures 1-3 As shown, in a preferred embodiment of the present invention, each of the partitions 2 and the inner wall of the separation tank 1 has a reflux slit 103. There is a communication port 104 between the bottom end of the partition 2 and the bottom plate of the separation tank 1. The reflux slit 103 is connected to the bottom end of the mixing chamber 101 through the communication port 104. The top end of the mixing chamber 101 is connected to the reflux slit 103 through the separation port 102. The water storage chamber 105 is connected to the reflux slit 103.

[0022] In practical application, during equipment operation, a small amount of incompletely degassed sludge will be carried by the fluid through the separation port 102 due to the continuous upward thrust of the sludge-water fluid at the bottom. After the fluid enters the return slit 103 area, the flow channel suddenly expands, the upward thrust dissipates rapidly, and the degassed sludge quickly settles into the return slit 103 under gravity. The settled sludge inside the return slit 103 can be returned to the bottom of the mixing chamber 101 through the bottom connection port 104. At the same time, the sewage sprayed from the water injection pipe 5 rises to form a negative pressure suction, actively sucking the returned sludge to replenish the reaction area, continuously stabilizing the sludge concentration inside the mixing chamber 101, avoiding sludge loss and insufficient reaction bacteria, and ensuring the continuous and stable operation of the sewage treatment reaction.

[0023] like Figures 1-3 As shown, in a preferred embodiment of the present invention, two symmetrically arranged inclined baffles 12 are fixedly installed on the inner wall of the separation tank 1. The inclined baffles 12 are located above the guide plate 3 and are arranged in parallel. The higher horizontal end of the inclined baffle 12 is fixedly connected to the inclined surface of the V-shaped plate 4. A vent hole is provided at the connection between the inclined baffle 12 and the V-shaped plate 4.

[0024] In practical application, the inclined baffle 12 can effectively intercept the mud-water mixture flowing out of the separation port 102, preventing fine sludge flocs from flowing upward into the high-level clear water area of ​​the water storage chamber 105. At the same time, the inclined structure of the inclined baffle 12 can guide the intercepted sludge to fall back down, assisting the sludge to settle and flow back. The vent holes at the connection between the inclined baffle 12 and the V-shaped plate 4 can ensure that the biogas after degassing flows upward normally without blocking the gas path or affecting biogas collection. Under the premise of not interfering with gas phase separation, it effectively prevents sludge from overflowing and improves the effluent quality of the water storage chamber 105.

[0025] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the bottom end of the separation tank 1 is connected to a sludge discharge pipe 8, and a valve 801 is provided on the sludge discharge pipe 8.

[0026] In practical application, this embodiment addresses the problem that existing equipment cannot promptly discharge aging sludge and inert impurities, which can easily lead to decreased bacterial activity and reduced treatment efficiency. Operators can control the opening and closing of valve 801 on the sludge discharge pipe 8 to periodically discharge aging and deactivated anaerobic sludge and deposited impurities from the separation tank 1. At the same time, fresh anaerobic sludge can be injected back into the separation tank 1 through the sludge discharge pipe 8 to quickly renew the reaction bacteria, continuously ensure the activity of sludge inside the mixing chamber 101, and maintain the long-term high efficiency of wastewater treatment and gas production capacity of the equipment.

[0027] like Figures 1-6 As shown, in a preferred embodiment of the present invention, two symmetrically arranged rotating plates 13 are rotatably installed on the inner wall of the separation tank 1. The rotating plates 13 are driven to rotate by a first driving source 1301 fixedly installed on the back of the separation tank 1. When the first driving source 1301 drives the rotating plates 13 to rotate to abut against the inclined baffle 12, the water storage cavity 105 is disconnected from the return seam 103.

[0028] In one embodiment, the first drive source 1301 may be a servo motor, a servo motor or other components, or other mechanisms capable of rotational motion. This embodiment does not impose specific limitations on these components.

[0029] In practical application, the first driving source 1301 can drive the rotating plate 13 to rotate and swing. When the rotating plate 13 is in contact with the inclined baffle 12, it can completely isolate the communication channel between the water storage chamber 105 and the return seam 103, realizing the partitioned closure of the upper and lower cavities. At this time, the lower mixing chamber 101 area can complete the sludge replacement and impurity cleaning operation through the sludge discharge pipe 8, and the clean water in the upper water storage chamber 105 can be normally retained. There is no need to completely empty the water body of the equipment, which effectively saves water resources and simplifies the equipment operation and maintenance process. At the same time, by adjusting the rotation angle of the rotating plate 13, the size of the flow gap between it and the inclined baffle 12 can be changed, and the flow area of ​​the mud and water fluid can be precisely controlled to adapt to the operating requirements of different sewage treatment loads.

[0030] like Figures 1-6 As shown, in a preferred embodiment of the present invention, a waste discharge pipe 17 is provided on both sides of the separation tank 1, and the two waste discharge pipes 17 are respectively connected to two reflux slits 103.

[0031] In practical application, the low-density flocculated impurities generated during the wastewater treatment reaction process, due to their low gas content and significant gravity settling effect, will fall into the return sludge 103 along with the return sludge. The high-density activated sludge inside the return sludge 103 settles at the bottom, while the light flocculated impurities accumulate on the upper layer of sludge. Workers can periodically extract the upper layer of flocculated impurities through the waste discharge pipe 17 connected to the return sludge 103 to achieve targeted cleaning of impurities and avoid long-term accumulation of impurities that pollute the sludge.

[0032] like Figures 1-6 As shown, in a preferred embodiment of the present invention, a first filter plate 14 is provided in the water storage cavity 105. The first filter plate 14 is fixedly installed on the inner wall of the separation tank 1 and on the inner wall of the V-shaped plate 4. The drain pipe 6 is located below the first filter plate 14. The water storage cavity 105 is connected to the cleaning pipe 16, which is located above the first filter plate 14. Two symmetrically arranged second filter plates 15 are rotatably installed in the water storage cavity 105. The second filter plates 15 are driven to rotate by a second drive source 1501 fixedly installed on the back of the separation tank 1. The second filter plates 15 are located above the V-shaped plate 4, and the top of the second filter plates 15 is above the liquid level in the separation tank 1. The bottom of the second filter plates 15 is connected to the top of the V-shaped plate 4.

[0033] In one embodiment, the second drive source 1501 may be a servo motor, a servo motor or other components, or other mechanisms capable of rotational motion. This embodiment does not impose specific limitations on these components.

[0034] In practical application, the first filter plate 14 inside the water storage chamber 105 can intercept and block the light, air-containing flocculents and fine scum entering the clear water area, preventing impurities from entering the lower drain pipe 6 and causing water pollution and pipe blockage. The second drive source 1501 can drive the second filter plate 15 to rotate continuously. The rotating second filter plate 15 can disturb the upper water flow in the water storage chamber 105, break the tiny air bubbles wrapped by the residual flocculents, and promote the flocculents to degas, increase in weight, and settle quickly. At the same time, the gas can be released, further enhancing the three-phase separation effect. During the rotation of the second filter plate 15, some impurity flocculents will adhere to it. When the plate surface with attached impurities rotates to the corresponding area of ​​the cleaning pipe 16, the suction effect of the cleaning pipe 16 can quickly remove the impurities on the plate surface and the accumulated impurities intercepted by the first filter plate 14, achieving a cleaning effect.

[0035] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
