Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a siphon pulse cyclone clarifier. Background Art

[0002] In drinking water treatment plants, pulse clarifiers purify raw water from surface water. They can effectively remove suspended impurities, colloids and other pollutants in raw water, so that the treated water quality meets the national drinking water hygiene standards. For example, in water plants in some small and medium-sized towns, pulse clarifiers have become the core water clarification treatment units due to their small footprint and good treatment effects, providing residents with safe and reliable drinking water. In the sewage treatment and reuse system, the pulse clarifier further clarifies the sewage that has undergone primary treatment, removes residual suspended matter and colloids, and makes the treated reclaimed water meet the reuse standards. It can be used in industrial circulating cooling water, urban landscape water replenishment, road spraying and other fields to achieve the recycling of water resources and alleviate the pressure of water shortage.

[0003] Its working principle is that the raw water after adding medicine enters the water inlet chamber, the water level gradually rises, and the air in the bell is compressed. When the water level exceeds the top of the central tube, the water overflows from the inner wall of the central tube, taking away the air on the top of the bell, creating a vacuum, triggering a siphon, and the water in the water inlet chamber flows down rapidly. When the water level drops below the siphon breaker mouth, air enters, the siphon stops, and the water level in the water inlet chamber rises again, and the cycle repeats to form a pulse. Under the action of the pulse, the raw water is ejected from the perforated water distribution pipe hole at a high speed, and violently mixed and reacted under the flow stabilizer. Then it flows upward at a slow speed to float the mud layer. The active mud in the suspended mud layer has an adsorption effect. Under the action of the pulsed water flow, the suspended layer sometimes expands and rises, and sometimes steadily descends, causing impurities and alum flakes in the water to collide and condense with each other. When the water flow rises to the top of the mud concentration chamber, the cross section expands, the flow rate decreases, the mud and water are separated, the clean water rises through the perforated water collection tank into the total water collection tank, and the mud flows into the mud concentration chamber and is discharged regularly.

[0004] The main structures include pulse generator system, water distribution and flow stabilization system, clarification system and mud discharge system.

[0005] For pulse clarifiers that use vacuum pulse generators, the vacuum pump is the key equipment to achieve the water level rise in the water inlet chamber. However, during the operation of the vacuum pump, the inside of the pump body is prone to sucking raw water, causing equipment damage. Once the vacuum pump is damaged, the pulse clarifier will not be able to generate pulses normally, affecting the water level control of the water inlet chamber and the formation of pulse water flow, thereby deteriorating the treatment effect of the entire clarifier. This is mainly due to the poor sealing performance of the vacuum pump, or the risk of raw water backflowing into the vacuum pump was not fully considered during the design, and there is a lack of effective protective measures.

[0006] The vacuum release valve (vacuum breaker) has a high operating frequency, with more than 1800 openings and closings per day. Frequent operations can easily lead to valve failures. Even if a backup valve is set, it is difficult to completely avoid accidents where the vacuum pump sucks in raw water due to valve failures. In addition, the vacuum break safety valve installed at the suction port of the vacuum pump is relatively rough in control, and it is prone to opening under low pressure or being difficult to close after opening, which will cause the pulse process to not be realized normally and affect the operation stability of the clarifier. This is because the design and selection of the vacuum release valve do not fully consider its high-frequency operation conditions, the quality and reliability of the valve are insufficient, and at the same time, the control system's monitoring and adjustment of the valve are not precise enough.

[0007] Great influence from raw water turbidity: When the turbidity of raw water is relatively high, such as in winter when the water level of Poyang Lake is low and artificial sand mining in the lake increases the turbidity of raw water to 1000 - 2000 degrees, it is very difficult to purify the siphon pulse clarifier, and it is easy to have the phenomenon of running alum flowers, the turbidity of the effluent increases, and the water production decreases. While in summer when the turbidity of raw water is relatively low, it cannot operate at an overloaded capacity and cannot meet the large water demand in summer. Summary of the Invention

[0008] In order to solve the above technical problems, the object of the present invention is to provide a stable siphon pulse cyclone clarifier with good flocculation effect.

[0009] To achieve the above object of the invention, the technical solution of the present invention is a siphon pulse cyclone clarifier, including a pool body, the pool body includes a water inlet area, a water distribution area, a clear water area, a sludge suspension area, a sludge concentration area, and a sludge collection area.

One end of the siphon pipe is located in the water inlet area and the other end is located in the water distribution area. The top of the siphon pipe is fixedly provided with the siphon break pipe, the air extraction pipe, and the siphon solenoid valve. The auxiliary siphon pipe is fixedly arranged below the air extraction pipe. The open end of the siphon break pipe is located in the water inlet area. The open end of the air extraction pipe is located in the water inlet area. The open end of the auxiliary siphon pipe is located in the water distribution area.

[0013] Further technical solution: A sludge return pipe is arranged between the sludge collection area and the water inlet pipe, and a sludge return solenoid valve is arranged on the sludge return pipe.

[0014] Further technical solution: A sludge discharge pipe is arranged between the sludge thickening area and the sludge collection area, and a sludge discharge solenoid valve is arranged on the sludge discharge pipe.

[0015] Further technical solution: The clear water area includes a porous water collecting pipe and a water outlet trough, and the porous water collecting pipe communicates with the water outlet trough.

[0016] Further technical solution: It includes an influent turbidity meter, and the influent turbidity meter is arranged in the water inlet area.

[0017] Further technical solution: It includes a control system, and the control system controls the influent turbidity meter, the siphon solenoid valve, the sludge discharge solenoid valve, and the sludge return solenoid valve.

[0018] The working principle of the present invention:

[0019] Before starting the siphon device, the siphon tube is filled with air and is in communication with the outside atmosphere. When starting to operate, the solenoid valve at the top of the siphon tube is closed, and water enters the water inlet area through the water inlet pipe. A small amount of water flows through the siphon auxiliary tube. When the water level submerges the nozzle of the siphon break tube, the air in the tube is gradually discharged. This process is similar to "priming" a common siphon tube until the air in the siphon tube is completely emptied and water continuously flows out of the water outlet. As the air in the siphon tube is exhausted, the pressure inside the tube rapidly decreases and approaches a vacuum state. At this time, on the side of the water inlet, due to the atmospheric pressure existing in the external water body, under the action of the pressure difference formed between the atmospheric pressure and the nearly vacuum state inside the siphon tube, water is "pressed" into the siphon tube. As the water continuously surges in, under the guidance of the horseshoe-shaped pipe, the water continuously flows towards the water outlet direction. As long as the water level at the water inlet remains relatively stable and is higher than the top of the siphon tube by a certain height to maintain a sufficient pressure difference, the siphon can continue, continuously introducing water into the siphon tube and transporting it to the water outlet. When the water level in the water inlet area drops to the nozzle of the siphon break tube, air starts to enter the siphon tube and the siphon automatically stops.

[0020] By controlling the opening and closing of the solenoid valve at the top of the siphon tube, each grid of water in the water inlet area undergoes timed alternating water drops after siphon pulses, causing the water flow to rotate in the water distribution area. Under the action of the swirling flow, suitable hydraulic conditions are provided for the collision and flocculation of particles, promoting the progress of the flocculation reaction. Due to the inertial effect of kinetic potential energy conversion, micro-vortices are generated, increasing the collision probability between particles. After the colloid is destabilized, the initially formed particles further undergo volume flocculation and form flocculated particles called secondary particles through multiple thixotropic changes. They uniformly pass through the perforated water distribution pipes and slowly flow upward in the sludge suspension area. Under the friction and extrusion rotation effects of the up and down cyclic backflow caused by the pulse action, a denser sludge suspension layer is formed.

[0021] The clarified water after precipitation is collected through a water collection device (such as a perforated water collection pipe), enters the clear water area, and then is discharged from the clarifier.

[0022] As the treatment process progresses, the continuously increasing sludge in the suspension layer will flow into the sludge collection area. A solenoid valve is set on the sludge discharge pipe to control the sludge discharge of each sludge collection area in turn at regular intervals and discharge it to the sludge thickening area to maintain the stability of the sludge concentration in the suspension layer and ensure the clarification effect.

[0023] When linked with the influent turbidity meter or during the initial operation, control the opening and closing of the sludge return electromagnetic valve to control the sludge return.

[0024] The advantages of the present invention are:

[0025] 1. The siphon device of the present invention mainly consists of a horseshoe-shaped siphon and a small amount of water level and air control components, with a simple and intuitive structure. This significantly reduces the equipment procurement cost, makes the installation process more convenient, eliminates the need for complex pipeline laying and debugging, shortens the construction period, greatly reduces the potential trouble spots, and improves the reliability of the system. Once started, as long as the water level at the water inlet remains stable, it can supply water continuously and stably. The special structure of the horseshoe-shaped siphon helps the water flow evenly and smoothly, reducing water flow fluctuations and turbulence phenomena. Moreover, due to its stable water flow characteristics, the siphon device can better adapt to water quality changes, ensuring that relatively stable pulse intensity and frequency can be maintained under different water quality conditions, and guaranteeing the treatment effect of the pulse clarifier.

[0026] 2. The horseshoe-shaped siphon of the present invention optimizes the water flow path, resulting in smaller head loss. During the operation of the pulse clarifier, a smaller head loss means lower energy consumption and can effectively save the operation cost. Especially in the case of a large water treatment volume, the long-term cumulative energy consumption savings are quite remarkable.

[0027] 3. The sludge suspension layer of the present invention improves the adaptability of the clarifier to water quality and water volume changes.

[0028] 4. The present invention strengthens the stirring intensity and extends the stirring time in the flocculation stage through tangential flow inlet water, enabling the coagulant to be fully mixed with the raw water, promoting the contact and reaction between suspended particles and the flocculant, and forming good flocs.

[0029] 5. When the turbidity of the raw water is high, the sludge volume in the sedimentation area increases. By setting a sludge discharge solenoid valve, the sludge discharge frequency is appropriately increased and the sludge discharge time is extended to timely discharge the sludge deposited at the bottom of the pool, preventing sludge floating and affecting the effluent water quality.

[0030] 6. The present invention is provided with a sludge thickening area and a sludge return pipe. When the turbidity of the raw water is low, sludge is returned. The returned sludge contains a certain amount of active microorganisms and flocs, which can provide more flocculation cores for low-turbidity raw water, promote the flocculation reaction, improve the sedimentation effect, and reduce the chemical agent consumption.

[0031] 7. The present invention is equipped with devices such as a water level sensor and a water quality monitor to real-time monitor the operation parameters of the clarifier. An automatic control system is configured to automatically adjust the operation of the equipment according to the monitored data, such as the pulse period, the time intervals of sludge discharge and slag discharge, and the sludge return time. The sludge discharge situation is real-time monitored to timely detect and handle abnormal problems, improve the production management efficiency, and reduce the manual operation intensity and the influence of human factors on the sludge discharge effect.

The siphon pulse swirl clarifier is adopted as the clarification / sedimentation process, with specific implementation methods.

[0039] I. Construction of the pool body.

[0040] Pool body design: According to the treatment water volume and site conditions, a circular pool body is designed. The pool body is composed of a water inlet area A, a water distribution area B, a sludge suspension area C, a sludge collection area F, a clear water area D, and channels connecting each area. The pool body adopts a reinforced concrete structure to ensure strength and impermeability. The thickness of the pool wall is determined according to mechanical calculations, generally 200 - 300 mm.

[0041] Partition design

[0042] Water inlet area A: The volume of the water inlet area A is determined according to the water inlet flow rate and the siphon start-up time to ensure there is enough space for the water level to rise to start the siphon. A water inlet pipe 1 is arranged in the water inlet area A, and the pipe diameter is calculated according to the design flow rate and the economic flow rate (generally 1.0 - 1.5 m / s).

[0043] Water distribution area B: A perforated water distribution pipe 4 is installed in water distribution area B, and the water distribution pipe is made of corrosion-resistant material. The perforation diameter is 8 - 12 mm, and the orifice velocity is controlled at 2 - 3 m / s.

[0044] Sludge suspension area C: Below water distribution area B is sludge suspension area C, with a height of 1.5 - 2.5 m. This area is the main place for flocculation and sludge-water separation. A flow stabilizer plate 5 is installed between sludge suspension area C and the perforated water distribution pipe 4.

[0045] Sludge collection area F: A sludge collection area F is set around sludge suspension area C. The collection area is separated from the suspension area by a baffle plate, and the sludge flows into the collection area by gravity. A sludge discharge pipe 8 is set at the bottom of sludge collection area F. The diameter of the sludge discharge pipe 8 is determined according to the sludge discharge volume and flow velocity (generally 1.5 - 2.0 m / s).

[0046] Clear water area D: The top of the tank body is clear water area D. A porous water collection pipe 6 is set in clear water area D to collect clear water into the water outlet trough 7. The diameter of the water collection pipe is calculated according to the clear water flow rate and flow velocity (generally 0.8 - 1.2 m / s). The orifice velocity on the water collection pipe is controlled at 0.5 - 0.8 m / s to ensure uniform water collection.

[0047] Sludge thickening area design: The volume is calculated according to the sludge retention time of 0.5 h - 1 h. The diameter of the sludge discharge pipe 12 is determined according to the sludge discharge volume and flow velocity (generally 1.5 - 2.0 m / s).

[0048] II. Equipment installation.

[0049] Installation of siphon device 2: A U-shaped siphon pipe 22 is installed between the water inlet area A and the water distribution area B. The siphon pipe 22 is made of stainless steel, and the diameter is determined according to the design flow rate and siphon flow velocity (generally 1.5 - 2.5 m / s). A siphon solenoid valve 21 is set at the top of the siphon pipe 22, and the siphon solenoid valve 21 is connected to the control system.

[0050] Installation of siphon auxiliary pipe 24: A siphon auxiliary pipe 24 is installed on one side of the siphon pipe 22, with a diameter of 50 - 80 mm. One end of the siphon auxiliary pipe 24 is connected to the water distribution area B, and the other end is connected to the siphon pipe 22 in the water inlet area A through an air extraction pipe 25 to ensure that water can flow smoothly into the siphon pipe 22 for auxiliary exhaust.

[0051] Installation of siphon break pipe 23: A siphon break pipe 23 is installed at an appropriate position below the top of the siphon pipe 22, with a diameter of 30 - 50 mm. One end of the siphon break pipe 23 is connected to the siphon pipe 22, and the other end opens into the water inlet area A. When the water level in the water inlet area A drops to the orifice of the siphon break pipe 23, air can enter the siphon pipe 22 to break the siphon.

[0052] Installation of sludge discharge system: Install sludge discharge solenoid valves 9 on the sludge discharge pipes 8 in each sludge collection area F. The sludge discharge solenoid valves 9 are connected to the control system to achieve periodic sludge discharge in turn. The sludge discharge pipes 8 lead to the sludge thickening area E, and the sludge thickening area E can operate intermittently to regularly discharge the thickened sludge for treatment.

The pipe diameter is determined according to the return sludge volume and flow rate (generally 1.0 - 1.5 m / s). Install a sludge return solenoid valve 11 on the sludge return pipe 10. The sludge return solenoid valve 11 is linked with the influent turbidity meter to control the sludge return according to the change of influent turbidity.

[0054] III. Commissioning and operation.

[0055] Equipment inspection: After installation, conduct a comprehensive inspection of all equipment, including the siphon pipe 22, siphon auxiliary pipe 24, siphon break pipe 23, various solenoid valves, sludge discharge pipes 8, sludge return pipes 10, etc., to ensure correct installation without problems such as blockage and leakage. Check the electrical system to ensure correct wiring and normal function of the control system.

[0056] Water injection and air exhaust: Before starting, close all solenoid valves and inject water into the water inlet area A. Water flows into the water inlet area A through the water inlet pipe 1, and a small amount of water flows through the siphon auxiliary pipe 24 into the siphon pipe 22 to gradually discharge the air in the siphon pipe 22. Observe the water outlet. When continuous water flow flows out, it indicates that the air in the siphon pipe 22 has been basically emptied.

[0057] Siphon start-up test: Close the siphon solenoid valve 21. As the water level in the water inlet area A rises to submerge the mouth of the siphon break pipe 23, observe whether the siphon starts. If the siphon starts smoothly, the water should quickly flow through the siphon pipe 22 into the water distribution area B to form a swirl in the water distribution area B. If the siphon does not start, check whether there are problems such as air leakage and blockage in the siphon pipe 22, and retest after troubleshooting.

[0058] Sludge discharge system commissioning: According to the designed sludge discharge cycle and discharge volume, set the opening time and opening sequence of the sludge discharge solenoid valve 9 on the sludge discharge pipe 8 in the sludge collection area F through the control system. Start the sludge discharge system, observe the sludge discharge effect, and ensure that the sludge can be smoothly discharged to the sludge thickening area E. Adjust the sludge discharge parameters to keep the sludge concentration in the suspension layer within a suitable range (generally 3 - 5 g / L).

[0059] Sludge return system commissioning: In the initial operation, manually control the opening and closing of the sludge return solenoid valve 11 to observe the influence of sludge return on the flocculation effect. After stable operation, link the sludge return solenoid valve 11 with the influent turbidity meter. When the influent turbidity increases, automatically increase the sludge return flow; when the influent turbidity decreases, appropriately reduce the sludge return flow to ensure good flocculation reaction effect.

[0060] Water quality monitoring and adjustment: During the commissioning operation, regularly monitor the influent and effluent water quality. The monitoring indicators include turbidity, suspended solids, COD, etc. According to the water quality monitoring results, adjust the operating parameters such as the siphon pulse period, sludge discharge period, and sludge return flow rate to enable the clarifier to achieve the best treatment effect and ensure that the effluent water quality meets the design requirements.

[0061] In the case of an influent turbidity of 600 - 1000 NTU after a heavy rainstorm, the effluent turbidity of the clarifier is within 1 NTU - 2 NTU. In the case of a general influent turbidity of 0 - 60 NTU, the effluent turbidity of the clarifier is within 1 NTU.
