Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a water treatment micro-power coagulation reaction device. Background Art

[0002] In the process of sewage treatment, coagulation process is often used to remove fine suspended matter and colloidal particles in water, thereby reducing the turbidity and color of wastewater and removing certain heavy metals and high molecular organic matter. In the prior art, the implementation form of coagulation process is mainly to add reagents to water, and disperse the reagents evenly in the wastewater through rapid mixing, and then slowly mix to form large settleable flocs. The flocs produced by coagulation are separated from the water through subsequent sedimentation or clarification, flotation and other processes.

[0003] The traditional coagulation process requires mechanical stirring while adding the reagent to ensure that the wastewater and the reagent are fully mixed. For example, the Chinese utility model patent with the authorization announcement number CN203017818U discloses a water treatment circulating reaction sedimentation tank, which includes a pool wall, a first flocculation chamber, an equipment room, a second flocculation chamber, a sedimentation chamber and a mud hopper, wherein the first flocculation chamber is provided with a stirring impeller connected to a flocculation mixer, the second flocculation chamber is equipped with a dosing pipe, and the sedimentation chamber is provided with an inclined tube filler. The device uses mechanical coagulation and mechanical flocculation instead of hydraulic coagulation and hydraulic flocculation, thereby making the mixing of the reagent and the sewage faster and more sufficient. However, in addition to increasing the initial equipment investment, the mechanical stirring equipment also consumes electricity during its operation, which will also increase the daily operating cost of the equipment.

[0004] In addition, there are also devices in the prior art that use a sprayer to spray flocculants. For example, the Chinese utility model patent with the authorization announcement number CN219110908U discloses a high-efficiency integrated oblique tube coagulation and sedimentation machine, which includes a sedimentation tank, an oblique tube and a sewage collecting hopper. The oblique tube is arranged in the sedimentation tank, and a feeding tank and a mixing tank are arranged on one side of the upper end of the sedimentation tank. The feeding tank is provided with a sprayer for adding flocculants. A diverter baffle is arranged in the feeding tank to achieve a diverter effect. Water flows down through the diverter baffle into the mixing tank. The bottom plate of the mixing tank is an oblique plate to facilitate the flow of sewage into the sedimentation tank. The device does not have an external force to assist the mixing of wastewater and chemicals. It only relies on the wastewater to be diverted through the diverter baffle and enter the mixing tank to achieve mixing. The mixing effect of wastewater and chemicals needs to be further improved.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the utility model includes a tank body 7, and a water inlet pipe 1 and a reaction tank group 12 are provided on one side of the upper end of the tank body 7, and a water outlet tank 8 and a water outlet pipe 9 are provided on the other side.

Figures 1 to 3 As shown, the reaction tank group 12 includes a first reaction tank 2, a second reaction tank 4 and a connecting tank 3, wherein the first reaction tank 2 and the second reaction tank 4 are arranged in parallel, and the corresponding ends of the first reaction tank 2 and the second reaction tank 4 are connected through the connecting tank 3 on the corresponding side, and the bottom of the first reaction tank 2 includes a first middle bottom plate 201 in the middle and first inclined bottom plates 202 on both sides, wherein as shown Figure 4 As shown, a transition chamber 11 is provided at the lower side of the first intermediate bottom plate 201, and the water inlet pipe 1 is connected to the transition chamber 11, a water inlet hole 2011 is provided on the first intermediate bottom plate 201, and the wastewater in the transition chamber 11 will flow into the first reaction tank 2 through the water inlet hole 2011, and a first ultrasonic vibrator 203 is provided on the first intermediate bottom plate 201, and the wastewater in the first reaction tank 2 flows into the second reaction tank 4 through the connecting grooves 3 on both sides, and a second ultrasonic vibrator 301 is provided in the connecting groove 3, the bottom of the second reaction tank 4 includes a second intermediate bottom plate 404 in the middle and second inclined bottom plates 405 on both sides, and a plurality of guide folds 403 are staggered along the length direction on the second inclined bottom plate 405, the second reaction tank 4 is provided with a first connecting hole 4021 at a position corresponding to the second intermediate bottom plate 404, a central tube 6 is provided inside the pool body 7, and as shown Figure 4As shown, the upper end of the central tube 6 is connected to the first connecting hole 4021 through the guide tube 5, and the lower end of the central tube 6 passes through the inclined tube filler 701 to form a water outlet port 601. The wastewater in the second reaction tank 4 flows into the lower end of the inclined tube filler 701 through the guide tube 5 and the central tube 6, so that the sludge and other impurities in the wastewater at the lower side of the inclined tube filler 701 can be precipitated and fall into the mud storage hopper 10, and then the wastewater rises through the inclined tube filler 701 and enters the upper part of the tank body 7, as shown in FIG. Figure 4 As shown, the height of the vertical plate 802 of the water outlet trough 8 located in the pool body 7 is lower than the height of the upper end of the pool body 7, so that the wastewater on the upper part of the pool body 7 overflows over the vertical plate 802 after reaching a certain height and flows into the water outlet trough 8. The middle part of the water outlet trough 8 is provided with a second connecting hole 801 connected to the water outlet pipe 9, so that the water in the water outlet trough 8 is discharged through the water outlet pipe 9. The inclined tube filler 701 is a well-known technology in the art, for example, the inclined tube filler structure in the CN219110908U patent can be adopted.

[0025] like Figures 1 to 5 As shown, the middle of the first reaction tank 2 is the first flocculating agent dosing point, wherein the size and number of the water inlet holes 2011 on the first middle bottom plate 201 in the middle of the first reaction tank 2 are calculated according to the amount of treated water, so that when the wastewater in the transition chamber 11 flows upward through each water inlet hole 2011 into the first reaction tank 2, a certain hydraulic stirring effect will be formed to achieve the preliminary mixing of the flocculant and the wastewater, and at the same time, the first ultrasonic vibrator 203 can generate ultrasonic waves uniformly around 360°, and there is a positive and negative pressure alternating cycle to generate ultrasonic vibration during the transmission process of the ultrasonic wave, and this vibration energy is transmitted in the wastewater liquid to further achieve the mixing of the flocculant and the wastewater. The bottom of the first reaction tank 2 is a structure with a low middle and gradually rising sides, so that the wastewater will have a certain residence time after entering the first reaction tank 2, so that the flocculant and the wastewater can be fully mixed under hydraulic stirring and ultrasonic vibration. The first ultrasonic vibrator 203 and the second ultrasonic vibrator 301 are both well-known in the art and are commercially available products. The ultrasonic vibrators in this embodiment are all JM-1006, with a frequency of 40 kHz and an ultrasonic power of 360 w.

[0026] like Figures 1 to 5 As shown, the bottom of the connecting groove 3 includes a first horizontal groove bottom plate 302, a groove bottom inclined plate 303 and a second horizontal groove bottom plate 304 connected in sequence, wherein the first horizontal groove bottom plate 302 is arranged at one end of the connecting groove 3 connecting with the first reaction groove 2, and the second horizontal groove bottom plate 304 is arranged at one end of the connecting groove 3 connecting with the second reaction groove 4, and as shown in Figure 5As shown, the height of the second horizontal trough bottom plate 304 is lower than that of the first horizontal trough bottom plate 302, and the second ultrasonic vibrator 301 is arranged on the first horizontal trough bottom plate 302. The wastewater in the first reaction tank 2 spreads and rises along the first inclined bottom plates 202 on both sides and then flows into the connecting grooves 3 on both sides. The connecting grooves 3 are the second flocculation agent dosing point. The wastewater and the agent in the connecting grooves 3 are fully mixed under the ultrasonic vibration formed by the second ultrasonic vibrator 301. Since the height of the second horizontal trough bottom plate 304 is lower than that of the first horizontal trough bottom plate 302, the wastewater can first fall into the space above the second horizontal trough bottom plate 304 for temporary storage to ensure the mixing time, and then rise and flow into the second reaction tank 4.

[0027] like Figures 1 to 5 As shown, a first partition is provided on one side of the second reaction tank 4 to separate it from the first reaction tank 2, and the two ends of the first partition are bent to form a baffle 401, and a second partition 402 is provided on the other side of the second reaction tank 4 to separate it from the other parts of the tank body 7, and an opening for wastewater to flow in is formed between the second partition 402 and the end of the baffle 401, and a second connecting hole 4021 is provided in the middle of the second partition 402. In this embodiment, each guide fold 403 on the second inclined bottom plate 405 is a V-shaped plate with equal spacing, and the wastewater flows back and forth along the channel formed by each guide fold 403, and during the flow, the water flow continuously hits the guide fold 403 to form a surge, thereby achieving multiple mixing of the wastewater and the flocculant, and then the wastewater flows into the guide pipe 5 through the first connecting hole 4021.

[0028] The working principle of the utility model is:

[0029] The utility model mainly utilizes the reaction tank group 12 to replace the traditional mechanical stirring equipment to achieve the full mixing of the flocculating agent and the wastewater during operation, wherein the wastewater first enters the transition chamber 11 at the lower middle part of the first reaction tank 2 through the water inlet pipe 1, and then the wastewater in the transition chamber 11 flows upward through the water inlet hole 2011 on the first intermediate bottom plate 201 to enter the first reaction tank 2. The middle part of the first reaction tank 2 is the first flocculating agent dosing point, and the upper side of the tank can be provided with a flocculant dosing pipe and other structures according to actual needs, and the size and number of the water inlet holes 2011 on the first intermediate bottom plate 201 in the middle of the first reaction tank 2 are based on the actual needs. According to the calculation of the treated water volume, when the wastewater in the transition chamber 11 flows upward through each water inlet hole 2011 into the first reaction tank 2, a certain hydraulic stirring effect will be formed to achieve preliminary mixing of the flocculant and the wastewater. At the same time, the first ultrasonic vibrator 203 can form ultrasonic vibrations 360° around to further promote the full mixing of the wastewater and the flocculant. The bottom of the first reaction tank 2 is a structure that is low in the middle and gradually rises on both sides. In this way, the wastewater will have a certain residence time after entering the first reaction tank 2, so that the flocculant and the wastewater can have sufficient time to achieve mixing under hydraulic stirring and ultrasonic vibration.

[0030] The wastewater in the first reaction tank 2 will overflow from both ends and flow into the connecting tanks 3 on both sides. The connecting tank 3 is the second flocculant dosing point. A flocculant dosing pipe and other structures can be set on the upper side of the tank according to actual needs. The wastewater and the agent in the connecting tank 3 are fully mixed under the ultrasonic vibration formed by the second ultrasonic vibrator 301. Since the height of the second horizontal tank bottom plate 304 is lower than the height of the first horizontal tank bottom plate 302, the wastewater can first fall into the space above the second horizontal tank bottom plate 304 for temporary storage to ensure the mixing time, and then rise and flow into the second reaction tank 4.

[0031] A plurality of guide folds 403 are staggered along the length direction on the second inclined bottom plates 405 on both sides of the second reaction tank 4. After the wastewater flows into the second reaction tank 4, it will flow downward along the channels formed by the guide folds 403 in a reciprocating manner, and during the flow, the water flow continuously hits the guide folds 403 to form surges, thereby achieving multiple mixing of the wastewater and the flocculant, thereby further ensuring the mixing effect of the wastewater and the flocculant, until the wastewater flows to the space above the first intermediate bottom plate 201 in the middle of the second reaction tank 4.

[0032] Then the wastewater flows into the lower end of the inclined tube filler 701 through the guide pipe 5 and the central tube 6 in sequence, and the sludge and other impurities in the wastewater at the lower side of the inclined tube filler 701 are precipitated and fall into the mud storage hopper 10. The mud storage hopper 10 is provided with a sewage outlet that can be opened regularly to realize the sludge cleaning. The liquid water rises through the inclined tube filler 701 and enters the upper part of the tank body 7. Figure 4As shown, the height of the vertical plate 802 of the water outlet trough 8 located in the pool body 7 is lower than the height of the upper end of the pool body 7, so that the waste water in the upper part of the pool body 7 overflows over the vertical plate 802 and flows into the water outlet trough 8 after reaching a certain height. The vertical plate 802 can also play a certain blocking role on impurities floating in the water. Then the water in the water outlet trough 8 enters the water outlet pipe 9 through the second connecting hole 801 and is discharged.
