Description

Technical Field

[0001] The invention relates to the technical field of coagulation reaction precipitation, and in particular to a coagulation reaction precipitator. Background Art

[0002] In the existing coagulation reaction sedimentation device, when the coagulant is added into the mixing zone, the water in the mixing zone rises, so that the coagulant added from the top is washed to the tube wall of the middle tube by the water flow before reacting with the impurities in the water, and adheres to the tube wall of the middle tube due to the adsorption of the coagulant itself, so that the dosage of the coagulant mixed with the water in the mixing zone is less than the dosage of the coagulant actually added, so that when the water to be purified in the reaction zone reacts with the coagulant, the reaction speed is too slow due to the insufficient dosage of the coagulant, so that part of the water that has not completed the reaction directly flows from the reaction zone to the sedimentation zone, and no flocs can be generated in the sedimentation zone, and no sedimentation can be made, resulting in the water that has not reacted directly floating on the upper layer of the sedimentation zone and being pumped out by the pump at the drain outlet, resulting in poor water purification effect.

[0003] Furthermore, in the existing coagulation reaction sedimentation device, after a period of water purification work, a large amount of floccules will be deposited in the sedimentation area. It is necessary to suspend the injection of water to be purified into the mixing area, stop the operation of the device, and discharge the large amount of floccules deposited in the lower layer of the sedimentation area in time, otherwise the floccules will float in the clean water in the upper layer of the sedimentation area, affecting the normal water purification work; however, this sewage discharge process takes a long time, and the water purification work is stopped for a long time. When the device is started again, it is necessary to carry out the above-mentioned water injection, coagulant addition and a series of water purification preparations again, which seriously affects the normal water purification efficiency.

[0004] Moreover, in the existing coagulation reaction sedimentation tank, the coagulant needs to be continuously added from the top of the mixing zone, and the direction of the coagulant addition is opposite to the rising direction of the water flow, which causes turbulence in the mixing zone and affects the mixing effect. Summary of the invention

[0005] In order to overcome the disadvantages of the existing coagulation reaction precipitator, in which the dosage of the coagulant mixed with water in the mixing zone is less than the dosage of the coagulant actually input, and the insufficient dosage of the coagulant causes the reaction speed to be too slow, so that part of the water that has not completed the reaction directly flows from the reaction zone into the sedimentation zone, and the unreacted water directly floats to the upper layer of the sedimentation zone and is pumped out by the pump at the drain outlet, resulting in poor water purification effect and inability to realize the sewage discharge function without stopping the machine, the present invention provides a coagulation reaction precipitator.

[0008] Furthermore, it also includes a non-stop sewage discharge mechanism; the non-stop sewage discharge mechanism includes an annular airbag and an arc-shaped magnetic strip; an annular airbag is installed at the lower part of the separation cylinder; a magnet strip is arranged at the lower part of the annular airbag; four arc-shaped magnetic strips are slidably connected to the base, and the four arc-shaped magnetic strips are annular as a whole.

[0009] Furthermore, the non-stop sewage discharge mechanism also includes a mounting plate, an electric push rod and an electromagnet; four mounting plates are installed at the lower part of the base; each mounting plate is installed with an electric push rod; the telescopic part of each electric push rod is fixed with an electromagnet, and the four electromagnets are respectively located below the corresponding side arc-shaped magnetic strips.

[0011] Furthermore, the non-stop sewage discharge mechanism also includes a ring and a filter; the inner side of the base is slidably connected to the ring; the base is provided with a filter, and the filter is flush with the lower surface of the ring; the filter divides the internal cavity of the base into a coagulation interception area and a clear water area, and the coagulation interception area is connected to the sewage outlet.

[0012] Furthermore, the base and the sedimentation cylinder are jointly provided with a water pipe; the water pipe connects the clean water area and the sedimentation area.

[0015] Furthermore, a large number of porous balls are placed in the mixing zone, the reaction zone and the precipitation zone; and a plurality of honeycomb inclined plates are placed on the upper layer of the precipitation zone.

[0016] The invention has the following beneficial effects: the invention wraps the inner wall of the middle tube with the isolation membrane, and replaces the inner wall of the middle tube with the isolation membrane, so that the inner wall of the middle tube will not come into contact with the coagulant in the mixing zone. At this time, the coagulant injected from the top is washed toward the isolation membrane by the water flow, and adheres to the isolation membrane due to the adsorption of the coagulant itself. The isolation membrane is driven by the upper and lower rollers to move in a rectangular track in a conveyor belt-like manner, so that after the isolation membrane adheres to the coagulant in the mixing zone, it moves upward, enters the L-shaped hollow plate from the water injection port, and then enters the mixing zone from the lower opening of the L-shaped hollow plate; in the process of the isolation membrane passing through the L-shaped hollow plate, the water injected from the water injection port continuously impacts the coagulant adhered to the surface of the isolation membrane, washes it off the surface of the isolation membrane, and mixes it into the water again; at the same time, the isolation membrane is in the inner part of the middle tube in a clean state, plays a role of replacing the inner wall of the middle tube, and avoids the formation of bulges on the inner wall of the middle tube. Such a cycle can ensure that the coagulant and water are fully mixed.

[0017] According to the present invention, after the annular airbag is deformed, its internal space is expanded. At this time, the water injection amount of the water injection port is reduced, so that the mixing zone and the reaction zone can carry out normal mixing and reaction, and the water flow will not quickly fill the internal space of the annular airbag, providing sufficient sewage discharge time for the sedimentation zone; in this way, both normal mixing and reaction work can continue and sewage discharge work can be carried out; the problem that the existing coagulation reaction sedimentator cannot realize sewage discharge without stopping the machine is solved. When the device is started again, it is necessary to carry out the above-mentioned water injection, coagulant addition and a series of water purification preparation work again, which seriously affects the normal water purification efficiency.

[0018] The present invention enables the water flow to start mixing with the coagulant as soon as it enters the mixing zone from the lower opening of the L-shaped hollow plate. Within the same mixing distance, the mixing time is increased, so that the coagulant and the water flow are mixed more evenly. In addition, the coagulant rises synchronously with the water flow, which solves the problem of the existing coagulation reaction precipitator that the coagulant needs to be continuously added from the top of the mixing zone, and the direction of the coagulant addition is opposite to the rising direction of the water flow, so that turbulence is generated in the mixing zone, affecting the mixing effect.

[0019] During the mixing, reaction and precipitation work, impurities in the mixing zone, reaction zone and precipitation zone are adsorbed on the surface of the porous balls, and the porous balls will collide with each other, causing the porous balls to flip over, adjusting the adsorption surface between the porous balls and the impurities, increasing the adsorption amount of impurities, and reducing the impurity content in the clean water.

[0020] When the clean water and flocs in the sedimentation area float up, after the clean water contacts the honeycomb inclined plate, it quickly floats to the upper layer of the sedimentation area under the guidance of the honeycomb inclined plate, and the flocs contact the honeycomb inclined plate and hit the plate surface, causing the direction of the flocs to change, and then settle downward, effectively reducing the amount of flocs in the upper clean water.

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Example 1

[0038] A coagulation reaction sedimentation vessel, such as Figure 1-Figure 14 As shown, it includes a base 1, a sedimentation cylinder 2, an L-shaped hollow plate 3 and a transmission unit; the sedimentation cylinder 2 is installed on the upper part of the base 1; the sedimentation cylinder 2 is bolted with a plurality of L-shaped hollow plates 3 distributed in a circular array; the L-shaped hollow plate 3 is provided with a water injection port 3a; and a plurality of transmission units distributed in a circular array are installed on the outer side of the sedimentation cylinder 2;

[0039] It also includes a connecting ring 4, a middle tube 5, a separating tube 6, an inner tube 7, a transmission unit and an isolation membrane 9; the lower parts of all L-shaped hollow plates 3 pass through the sedimentation tube 2 and are connected to a connecting ring 4; the upper part of the connecting ring 4 is fixedly connected to the middle tube 5, and the middle tube 5 is located inside the sedimentation tube 2; the lower part of the connecting ring 4 is fixedly connected to the separating tube 6; the separating tube 6 is fixedly connected to the inner tube 7, and the inner tube 7 is located inside the middle tube 5; a mixing zone 1000 is formed between the middle tube 5 and the inner tube 7; the interior of the inner tube 7 is a reaction zone 2000, and the upper part of the reaction zone 2000 It is connected with the mixing zone 1000; a sedimentation zone 3000 is formed between the middle tube 5 and the sedimentation cylinder 2, and the sedimentation zone 3000 is connected with the reaction zone 2000; the separation cylinder 6 separates the mixing zone 1000 and the sedimentation zone 3000; the transmission unit is connected with an isolation membrane 9; the isolation membrane 9 moves inside the L-shaped hollow plate 3, and the isolation membrane 9 is in contact with the inner side surface of the L-shaped hollow plate 3 close to the sedimentation cylinder 2, and the L-shaped hollow plate 3 is in contact with the inner side surface of the middle tube 5; the inner wall of the middle tube 5 is wrapped by a plurality of isolation membranes 9.

[0040] It also includes a toggle bar 10; each isolation membrane 9 is provided with a plurality of toggle bars 10 distributed in an array along the overall curve of the isolation membrane 9, and two adjacent toggle bars 10 are in an "eight" shape; the toggle bar 10 is set to a rubber material; when the isolation membrane 9 moves in a rectangular track, the toggle bar 10 moves with the isolation membrane 9, and the water in the mixing area 1000 is pushed upward by the toggle bar 10, thereby increasing the water flow rate. At the same time, the water flow is slightly stirred to increase the mixing effect of the water flow and the coagulant. The "eight" shape structure of the toggle bar 10 has a better toggle effect.

[0041] The transmission unit includes a bearing seat 81, a motor 82 and a roller 83; four bearing seats 81 distributed in a rectangular shape are installed on the outer side of the sedimentation cylinder 2; the two upper bearing seats 81 are connected to a roller 83 for rotation together; the two lower bearing seats 81 are connected to another roller 83 for rotation together; the upper and lower bearing seats 81 are each installed with a motor 82, and the output shafts of the two motors 82 are respectively fixedly connected to the rollers 83 on the corresponding sides; the two rollers 83 are connected to the isolation membrane 9 for transmission together, and the isolation membrane 9 is driven to move in a rectangular trajectory through the two rollers 83.

[0042] The water purification work of the present invention is specifically as follows:

[0043] First, water to be purified is injected into the L-shaped hollow plate 3 from the water injection port 3a, and reaches the inside of the middle tube 5, i.e., the mixing zone 1000, through the L-shaped hollow plate 3 and the connecting ring 4 in turn; as more water is injected, the water in the mixing zone 1000 slowly overflows, and when the water level in the mixing zone 1000 exceeds the height of the inner tube 7, it begins to flow into the inner tube 7, i.e., from the mixing zone 1000 to the reaction zone 2000. Under the influence of gravity, the water passes through the reaction zone 2000 and reaches the sedimentation zone 3000. When the mixing zone 1000, the reaction zone 2000, and the sedimentation zone 3000 are all filled with water, the water to be purified can flow between the mixing zone 1000, the reaction zone 2000, and the sedimentation zone 3000 in turn;

[0044] At this time, the water purification work can be started. Water is continuously injected into the L-shaped hollow plate 3 through the water injection port 3a. At the same time, the water in the upper layer of the sedimentation area 3000 is pumped out through the external pump machine through the drainage port 2a, so that after the water flows into the mixing area 1000, it flows from the mixing area 1000 from bottom to top to the reaction area 2000, and then flows from the reaction area 2000 from top to bottom to the sedimentation area 3000. In this process, the water flows in a "W" shape trajectory. After multiple During this process, a coagulant is added into the mixing zone 1000, the water to be purified is uniformly mixed with the coagulant in the mixing zone 1000, rapidly reacts with the coagulant in the reaction zone 2000, and flocculation and sedimentation occur in the sedimentation zone 3000. The flocculants are deposited in the lower layer of the sedimentation zone 3000, and are washed and floated on the upper layer of the sedimentation zone 3000. The external pump is controlled to pump out the water in the upper layer of the sedimentation zone 3000 through the drain port 2a to perform conventional water purification work.

[0045] In the existing coagulation reaction sedimentation device, when the coagulant is added into the mixing zone 1000, the water in the mixing zone 1000 rises, so that the coagulant added from above is washed toward the wall of the middle tube 5 by the water flow before reacting with the impurities in the water, and adheres to the wall of the middle tube 5 due to the adsorption of the coagulant itself, so that the dosage of the coagulant mixed with the water in the mixing zone 1000 is less than the dosage of the coagulant actually added, so that when the water to be purified in the reaction zone 2000 reacts with the coagulant, the reaction speed is too slow due to the insufficient dosage of the coagulant, so that part of the water that has not completed the reaction directly flows from the reaction zone 2000 into the sedimentation zone 3000, and no flocs can be generated in the sedimentation zone 3000, and no sedimentation can be made, so that the water that has not reacted directly floats to the upper layer of the sedimentation zone 3000 and is pumped out by the pump at the drain port 2a, resulting in poor water purification effect;

[0046] At the same time, after a long period of water purification, more and more coagulants adhere to the wall of the middle tube 5, forming bulges. The bulges occupy the space inside the middle tube 5, resulting in a decrease in the water flow rate of the middle tube 5, and a decrease in the water flow rate between the mixing zone 1000, the reaction zone 2000 and the sedimentation zone 3000, thereby reducing the overall water purification efficiency.

[0047] The present invention wraps the inner wall of the middle tube 5 with the isolation membrane 9, and replaces the inner wall of the middle tube 5 with the isolation membrane 9, so that the inner wall of the middle tube 5 will not come into contact with the coagulant in the mixing zone 1000. At this time, the coagulant injected from the top is rushed to the isolation membrane 9 by the water flow, and adheres to the isolation membrane 9 due to the adsorption of the coagulant itself. At the same time, taking the transmission unit on the right side of the sedimentation cylinder 2 as an example, the output shaft of the control motor 82 drives the roller 83 to rotate clockwise from the front to the back, and drives the isolation membrane 9 to move in a rectangular track in a conveyor-like manner through the upper and lower rollers 83, so that after the isolation membrane 9 adheres to the coagulant in the mixing zone 1000, it moves upward, and then enters the L-shaped hollow plate 3 from the water injection port 3a, and then enters the mixing zone 1000 from the lower opening of the L-shaped hollow plate 3; in the process of the isolation membrane 9 passing through the L-shaped hollow plate 3, the water injected from the water injection port 3a continuously impacts the coagulant adhered to the surface of the isolation membrane 9, While it is flushed down from the surface of the isolation membrane 9, it is mixed into the water again; at the same time, the isolation membrane 9 is in a clean state inside the middle tube 5, playing the role of replacing the inner wall of the middle tube 5, avoiding the formation of bulges on the inner wall of the middle tube 5, and such a cycle can ensure that the coagulant and water are fully mixed; the problem of the existing coagulation reaction precipitator is solved, that the dosage of the coagulant mixed with water in the mixing area 1000 is less than the dosage of the coagulant actually input, so that when the water to be purified in the reaction area 2000 reacts with the coagulant, the reaction speed is too slow due to the insufficient dosage of the coagulant, so that part of the water that has not completed the reaction directly flows from the reaction area 2000 into the sedimentation area 3000, and no flocs can be generated in the sedimentation area 3000, and no sedimentation can be made, resulting in the water that has not reacted directly floating on the upper layer of the sedimentation area 3000 and being pumped out by the pump at the drain outlet 2a, resulting in poor water purification effect, and the efficiency of water purification work is improved.

[0048] Example 2

[0049] On the basis of Example 1, it also includes a non-stop sewage discharge mechanism; the non-stop sewage discharge mechanism includes an annular airbag 101 and an arc-shaped magnetic strip 102; an annular airbag 101 is installed at the lower part of the separation tube 6; a magnet strip is arranged at the lower part of the annular airbag 101; an air pump is arranged in the separation tube 6, and gas is injected into the annular airbag 101 through the air pump to control the expansion or contraction of the annular airbag 101; four arc-shaped magnetic strips 102 are slidably connected to the bottom of the base 1, and the four arc-shaped magnetic strips 102 are annular as a whole, and the arc-shaped magnetic strips 102 are set to be made of magnet material.

[0050] The non-stop sewage discharge mechanism also includes a mounting plate 103, an electric push rod 104 and an electromagnet 105; four mounting plates 103 distributed in a circular array are installed on the lower surface of the base 1; each mounting plate 103 is installed with an electric push rod 104; the telescopic part of each electric push rod 104 is fixed with an electromagnet 105, and the four electromagnets 105 are respectively located below the corresponding side arc-shaped magnetic strips 102, and the electromagnet 105 is driven to contract by the telescopic part of the electric push rod 104, so that the electromagnet 105 drives the four arc-shaped magnetic strips 102 to slide toward its edge at the bottom of the base 1.

[0051] The lower surface of the annular airbag 101 is provided with a plurality of air holes 101a distributed in a circular array, and the air holes 101a are arranged to be inclined outward; when the annular airbag 101 expands downward, air flow is sprayed toward the bottom of the base 1 through the air holes 101a, and the concrete in the central area of ​​the bottom of the base 1 is blown toward the edge of the bottom of the base 1 through the air flow.

[0052] The non-stop sewage discharge mechanism also includes a ring 111 and a filter 112; the inner side surface of the base 1 is slidably connected to a ring 111 that slides in the up and down directions, and the ring 111 has a built-in electric drive component, which drives the ring 111 to slide up and down through electric drive; a filter 112 is arranged inside the base 1, and the filter 112 is flush with the lower surface of the ring 111; the filter 112 divides the internal cavity of the base 1 into a coagulation interception area 001 and a clear water area 002, and the coagulation interception area 001 is connected to the sewage outlet 1a; the coagulation interception area 001 is opened or closed by the up and down sliding of the ring 111.

[0053] The base 1 and the sedimentation cylinder 2 are jointly provided with a water pipe 113; the water pipe 113 connects the clean water area 002 and the sedimentation area 3000, and the water in the clean water area 002 is injected into the sedimentation area 3000 again through the water pipe 113, instead of being directly discharged together with the flocculants, effectively reducing the waste of water resources.

[0054] In the existing coagulation reaction sedimentation device, after a period of water purification work, a large amount of floccules will be deposited in the sedimentation area 3000. It is necessary to stop injecting the water to be purified into the mixing area 1000, stop the operation of the device, and discharge the large amount of floccules deposited in the lower layer of the sedimentation area 3000 in time, otherwise the floccules will float in the clean water in the upper layer of the sedimentation area 3000, affecting the normal water purification work; however, this sewage discharge process takes a long time, and the water purification work is stopped for a long time. When the device is started again, it is necessary to carry out the above-mentioned water injection, coagulant addition and a series of water purification preparations again, which seriously affects the normal water purification efficiency.

[0055] The non-stop sewage discharge operation of the present invention is specifically as follows:

[0056] It should be noted that the annular airbag 101 is initially in a contracted state, and the water flow between the reaction zone 2000 and the precipitation zone 3000 can flow normally; Fig.10 The blocked state is shown.

[0057] When a large amount of floccules are deposited in the lower layer of the precipitation zone 3000, the air pump is controlled to inject gas into the annular airbag 101, so that the annular airbag 101 expands downward until the lower inner part of the annular airbag 101 fits with the arc-shaped magnetic strip 102, and the magnet strip in the lower inner part of the annular airbag 101 is adsorbed with the arc-shaped magnetic strip 102, so that the annular airbag 101 and the arc-shaped magnetic strip 102 form a sealed state, thereby isolating the reaction zone 2000 and the precipitation zone 3000;

[0058] The clean water on the upper layer of the sedimentation area 3000 is then pumped out, leaving only a part of the clean water and deposited flocs in the sedimentation area 3000. Subsequently, the electric drive is controlled to drive the ring 111 to slide upward, so that the coagulation interception area 001 is opened, and then the sedimentation area 3000 and the coagulation interception area 001 are connected, so that the flocs in the sedimentation area 3000 can smoothly enter the coagulation interception area 001 when squeezed.

[0059] Subsequently, the electromagnet 105 is controlled to absorb the arc-shaped magnetic strip 102 on the corresponding side, and then the telescopic part of the electric push rod 104 drives the electromagnet 105 on the corresponding side to contract, so that the electromagnet 105 drives the arc-shaped magnetic strip 102 on the corresponding side away from the central area of ​​the annular airbag 101, and the arc-shaped magnetic strip 102 drives the lower part of the annular airbag 101 away from the central area of ​​the sedimentation area 3000, so that the annular airbag 101 is transformed from a circular ring 111-shaped state to a truncated cone-shaped state with a small top and a large bottom, and the sediment on the lower edge of the annular airbag 101 is squeezed toward the edge area of ​​the sedimentation area 3000, while expanding the internal space of the annular airbag 101, so that the reaction area 2000 has enough reaction space, and the flocculants squeezed by the lower part of the annular airbag 101 are squeezed into the coagulation interception area 001, and are pumped out through the pump machine external to the sewage outlet 1a.

[0060] After the annular airbag 101 completes its deformation, the pump connected to the sewage outlet 1a is controlled to extract the flocculants deposited at the bottom of the sedimentation area 3000 through the sewage outlet 1a and the coagulation interception area 001. When all the flocculants deposited at the bottom of the sedimentation area 3000 are extracted, it means that the sewage discharge work is completed, and the electromagnet 105, the annular airbag 101, the arc-shaped magnetic strip 102, and the ring 111 are restored to their initial states to carry out normal mixing, reaction, and sedimentation work; in this process, the filter screen 112 intercepts the flocculants in the coagulation interception area 001 above the filter screen 112, and the cleaning that follows the flocculants into the coagulation interception area 001 passes through the filter screen 112 to reach the clean water area 002, and the water in the clean water area 002 is injected into the sedimentation area 3000 again through the water pipe 113, instead of being directly discharged together with the flocculants, effectively reducing the waste of water resources.

[0061] When the annular airbag 101 expands downward, airflow is ejected toward the bottom of the base 1 through the air hole 101a, and the floccules in the central area of ​​the sedimentation area 3000 are blown toward the edge of the sedimentation area 3000 by the airflow, so that the floccules are blown into the coagulation interception area 001; at the same time, the annular airbag 101 is prevented from being clamped by the annular airbag 101 and the arc-shaped magnetic strip 102 and unable to be discharged when the annular airbag 101 and the arc-shaped magnetic strip 102 are adsorbed;

[0062] During this process, after the annular airbag 101 is deformed, its internal space is expanded. At this time, the water injection amount of the water injection port 3a is reduced, so that the mixing zone 1000 and the reaction zone 2000 can carry out normal mixing and reaction, and the water flow will not quickly fill the internal space of the annular airbag 101, providing sufficient sewage discharge time for the sedimentation zone 3000; in this way, both normal mixing and reaction work can continue and sewage discharge work can be carried out; the problem of the existing coagulation reaction sedimentation device that cannot realize sewage discharge without stopping the machine is solved. When the device is started again, it is necessary to carry out the above-mentioned water injection, coagulant addition and a series of water purification preparation work again, which seriously affects the normal water purification efficiency.

[0063] Example 3

[0064] On the basis of Example 2, the coagulation addition mechanism includes a hollow ring 201, a rotating part 202 and a liquid passing pipe 203; the hollow ring 201 is fixedly connected to the lower part of the inner tube 7, and the hollow ring 201 is located in the upper inner part of the separation tube 6; the rotating part 202 is rotatably connected to the lower part of the inner tube 7, and the rotating part 202 is rotatably connected to the hollow ring 201; the rotating part 202 has a built-in electric drive mechanism, which drives the rotating part 202 to rotate; a liquid passing cavity 100 is arranged inside the hollow ring 201; the rotating part 202 is provided with a plurality of liquid outlet troughs 200, and the liquid outlet troughs 200 are connected to the liquid passing cavity 100, and the liquid outlet troughs 200 are connected to the mixing zone 1000; the liquid passing cavity 100 is connected to the liquid passing pipe 203, and the liquid passing pipe 203 passes through the separation tube 6 and the sedimentation tube 2 in sequence and is connected to the external coagulant addition equipment.

[0065] In the existing coagulation reaction sedimentation tank, the coagulant needs to be continuously added from the top of the mixing zone 1000. The direction of the coagulant addition is opposite to the rising direction of the water flow, which causes turbulence in the mixing zone 1000 and affects the mixing effect.

[0066] The efficient mixing work of the coagulant of the present invention is as follows:

[0067] When the water to be purified is injected into the mixing zone 1000 from the lower opening of the L-shaped hollow plate 3, the external coagulant injection device is controlled to inject the coagulant into the rotating member 202 through the liquid pipe 203, so that the coagulant reaches the liquid passage cavity 100; at the same time, the electric drive mechanism is controlled to drive the rotating member 202 to rotate, and the rotating member 202 rotates rapidly. Under the action of centrifugal force, the coagulant in the liquid passage cavity 100 is thrown out through the liquid outlet trough 200, and then mixed into the mixing zone 1000, and quickly mixed with the water to be purified in the mixing zone 1000. The mixing allows the water to start mixing with the coagulant as soon as it enters the mixing zone 1000 from the lower opening of the L-shaped hollow plate 3. Within the same mixing distance, the mixing time is increased, so that the coagulant and water are mixed more evenly, and the coagulant rises synchronously with the water flow, which solves the problem of the existing coagulation reaction precipitator that the coagulant needs to be continuously added from the top of the mixing zone 1000, and the direction of the coagulant addition is opposite to the rising direction of the water flow, which causes turbulence in the mixing zone 1000 and affects the mixing effect.

[0068] It also includes arc-shaped oblique bars 11; each connecting ring 4 is provided with a plurality of arc-shaped oblique bars 11, and the number of the arc-shaped oblique bars 11 matches the number of the L-shaped hollow plates 3, and the arc-shaped oblique bars 11 are opposite to the lower opening of the L-shaped hollow plates 3; water to be coagulated is injected into the L-shaped hollow plates 3 from the water injection port 3a, and this part of the water passes through the inside of the L-shaped hollow plates 3, and when it reaches the lower opening of the L-shaped hollow plates 3, this part of the water contacts the arc-shaped oblique bars 11, and is guided by the arc-shaped oblique bars 11, so that the water flowing out of the lower opening of the L-shaped hollow plates 3 can flow directly upward, avoiding that this part of the water flow directly collides with the coagulant.

[0069] like Fig.14 As shown, a large number of porous balls are placed in the mixing zone 1000, the reaction zone 2000 and the sedimentation zone 3000; during the mixing, reaction and sedimentation work, the impurities in the mixing zone 1000, the reaction zone 2000 and the sedimentation zone 3000 are adsorbed on the surface of the porous balls, and the porous balls collide with each other, causing the porous balls to flip, adjusting the adsorption surface of the porous balls and the impurities, increasing the adsorption amount of the impurities, and reducing the impurity content in the clean water; a number of honeycomb inclined plates are placed on the upper layer of the sedimentation zone 3000; when the clean water and flocculants in the sedimentation zone 3000 float up, after the clean water contacts the honeycomb inclined plates, it is guided by the honeycomb inclined plates and quickly floats to the upper layer of the sedimentation zone 3000, and the flocculants contact the honeycomb inclined plates and hit the plate surface, causing the direction of the flocculants to change, and then settle downward, effectively reducing the amount of flocculants in the upper clean water.
