Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and more specifically to a cyclone flotation clarifier siphon filter. Background Art

[0002] Cyclone flotation clarification and U-shaped siphon filter are two common water treatment processes. Cyclone flotation clarification is a water treatment technology that combines the principles of cyclone separation and flotation sedimentation. This process first uses a coagulant to condense suspended particles and organic matter such as grease in the water into large particles, and then uses a cyclone to produce a cyclone effect, so that these large particles are deposited to the bottom of the pool under the action of centrifugal force. At the same time, gas is injected into the water to form a large number of tiny bubbles. These bubbles will adhere to the surface of pollutants such as organic matter and grease, causing them to form scum and float to the water surface. Finally, the scum is removed by a scraping device to achieve water purification;

[0003] Among them, the U-shaped siphon filter is a water treatment equipment that uses the siphon principle for filtration. Its main feature is that it does not require external power during the filtration process. The siphon effect is automatically formed through the water level change in the filter, so that water is filtered through the filter layer. The U-shaped siphon filter is usually composed of an inlet channel, a filter body, an outlet channel and a siphon pipe. During the filtration process, water enters the filter from the inlet channel, and after being filtered by the filter layer, the clean water flows out from the outlet channel. When the water level in the filter drops to a certain level, the siphon pipe starts to work, pumping out the water in the filter, and allowing air to enter the filter to form a negative pressure, sucking away the pollutants on the filter layer, thereby completing the backwashing process of the filter;

[0004] The above-mentioned cyclone flotation clarification and U-shaped siphon filter can be used in combination during actual use, but the floor space occupied by the two is too large, thus causing unnecessary economic waste. At the same time, the above-mentioned two are mainly provided with wind energy by Roots blowers during use, but in actual use, a filter device is installed on the surface of the Roots blower to isolate external dust and impurities. With the increase of use time, the particles inside the filter device will gradually accumulate, especially in high temperature and high humidity environments, the blockage will be more serious. When the air inlet filter device is blocked, the airflow of the Roots blower will be hindered, resulting in increased resistance to the airflow, thereby affecting the normal operation of the Roots blower. The blockage will cause a decrease in air flow and a decrease in the operating speed of the rotor, thereby increasing the torque of the Roots blower. In order to maintain the stability of the torque, the motor will increase the current output, which may cause the motor to be overloaded or damaged, thereby causing certain economic losses.

A water collecting channel 26 is installed on the other side of the filter tank water collecting pipe 25, and a clear water tank pipeline 27 is installed on the side of the water collecting channel 26.

[0033] In the embodiments of the present application, the specific working process of the embodiments of this part of the application is as follows: after the raw water is dosed with coagulant, it is mixed evenly at high speed by a water pump or mixer, enters a gradual flow hydraulic state to complete the destabilization of the colloid, and enters the high-efficiency volume flocculation chamber 1 from the lower part of the clarification tank through the water inlet pipe 5. After the rising water flows through the flow disturbance device, a large number of micro-vortices of different sizes are generated due to the inertial effect of the conversion of kinetic potential energy. The initial particles in the micro-vortices contact and collide due to the inertial effect, thereby causing volume flocculation in the entire reaction zone; the water flow enters the high volume concentration contact flocculation chamber 2 after being buffered, and the initial particles undergo multiple contacts and deformations in the process of rising along the water flow to form dense flocculated particles, which we call secondary particles; the water flow then passes through the small circulation floc contact chamber 3 into the radiation circulation diversion channel 4 and flows into the sedimentation area. The flocculation chamber is provided with a mesh disturbance device. At the same time, the gas dissolved in the water and the microbubbles generated by the cavitation of the first-stage pump produce a flotation effect on some organic matter and some algae in the water due to the decompression, so that the alum flowers, organic matter and some algae that are lighter than the specific gravity of water are removed by flotation; the water body with secondary particles enters the sedimentation area evenly through hydraulic distribution, and the grown and dense settled flocs enter the sedimentation area and are discharged from the mud discharge umbrella cover 12 to the sedimentation and mud discharge area 23 through the mud discharge pipe 13. The other part rises with the water flow, and during this period, it forms a dense active agglomerated flocculation sphere under the friction and extrusion rotation of the up and down circulation reflux with the sliding active mud residue after the mud and water separation through the inclined tube 10, and continuously absorbs some organic matter and trace toxic heavy metal elements in the water. When passing through the sedimentation area of ​​the inclined tube 10, Due to the increase in the specific gravity of the flocs, the mud and water are well separated. The semi-finished clean water has a turbidity of no more than 1NTU and enters the water collection tank 14. After being collected by the water collection system, it enters the filter tank through the water collection main channel and then enters the filter tank through the small siphon 15. After the pre-filter water penetrates the quartz sand 22, pebbles 21, nylon mesh 20 and filter plate 19, the turbidity is about 0.2NTU. It is collected into the water collection channel 26 through the filter tank water collection pipe 25 and flows into the clean water tank through the pipe 27. When the interception capacity of the filter material deteriorates, backwashing is automatically performed. The backwashing is water backwashing and air-water backwashing. During water backwashing, the sewage is pumped through the sand washing tank 18 to the large siphon pipe 16 and the large siphon reducer 17 and discharged into the mud discharge area 23; during air-water backwashing, water flushing continues, and the air flushing function is turned on to enter the filter tank filter plate through the air pipe 29 of the Roots blower 28.

The Roots blower (28) comprises an air inlet device (2801), a frame (2802) is installed at the air inlet end of the air inlet device (2801), a support rod is movably sleeved on the inner wall at the bottom of the frame (2802), a filter device (2803) is installed on the outer wall at the middle position of the support rod, a rubber ring is installed at the connection between the filter device (2803) and the frame (2802), and a wind speed sensor is installed inside the air inlet device (2801); The inner wall of the side of the frame (2802) is penetrated and connected with a hollow column (2804); the inner wall of the frame (2802) is provided with an air chamber at a position close to the hollow column (2804), which is conducive to the compressed air being transported to the inside of the hollow column (2804) through the air chamber; the side of the hollow column (2804) is penetrated and fixedly connected with a spray gun port (2805); the inner wall of the spray gun port (2805) is installed with a sealing plate (2806) at a position away from the hollow column (2804); and a torsion spring device is installed at the connection between the sealing plate (2806) and the spray gun port (2805); A delivery pipe (2810) is installed in the air chamber of the hollow column (2804), and an air pump (2809) is installed in the delivery pipe (2810) at a position away from the air chamber; A micro vibration pump (2807) is installed on the side of the filter device (2803), and a U-shaped telescopic column (2808) is installed on the side of the micro vibration pump (2807). The U-shaped telescopic column (2808) is composed of a plurality of sets of U-shaped columns connected together. A micro delivery pipe is installed on the side of the U-shaped telescopic column (2808). The compressed air generated by the air pump (2809) is delivered to the inside of the U-shaped telescopic column (2808) through the micro delivery pipe, driving the U-shaped telescopic column (2808) to perform a stretching operation, thereby driving the filter device (2803) to rotate ninety degrees; The working process of a cyclone flotation clarifier siphon filter is as follows: Step 1: After the raw water is dosed with coagulant, it is mixed evenly at high speed by a water pump or mixer, enters a gradual flow hydraulic state to complete the destabilization of the colloid, and enters a high-efficiency volume flocculation chamber (1) from the lower part of the clarification tank through a water inlet pipe (5). After the rising water flows through a flow disturbance device (7), a large number of micro-vortices of different sizes are generated due to the inertial effect of kinetic potential energy conversion. The initial particles in the micro-vortices come into contact and collide due to the inertial effect, thereby causing volume flocculation in the entire reaction zone. After being buffered, the water flow enters a high volume concentration contact flocculation chamber (2), and the initial particles undergo multiple contacts during the process of rising along the water flow. The water flows into the sedimentation zone through the small circulation floc contact chamber (3) and the radial circulation diversion channel (4). The flocculation chamber is provided with a mesh flow disturbance device. At the same time, the gas dissolved in the water and the microbubbles generated by the cavitation of the first-stage pump produce a flotation effect on some organic matter and some algae in the water due to the reduced pressure, so that the flocs, organic matter and some algae lighter than the specific gravity of water are removed by flotation. The water body with secondary particles enters the sedimentation zone evenly through hydraulic distribution, and the grown and dense precipitated flocs enter the sedimentation zone and are discharged from the mud discharge umbrella cover (12) through the mud discharge pipe (1 3) discharged to the sedimentation and sludge discharge area (23), and the other part rises with the water flow. During this period, the active sludge that slides down after the separation of mud and water through the inclined pipe (10) forms a dense active agglomerated flocculation ball under the friction and extrusion rotation of the up and down circulation reflux, and continuously absorbs part of the organic matter and trace toxic heavy metal elements in the water. When passing through the sedimentation area of ​​the inclined pipe (10), the specific gravity of the floc increases, and the mud and water are well separated. The semi-finished clear water, with a turbidity of no more than 1NTU, enters the water collection tank (14), is collected by the water collection system, and enters the filter tank through the water collection main channel, and enters the filter tank through the small siphon (15). The water before filtration penetrates After the quartz sand (22), pebbles (21), nylon mesh (20), and filter plates (19), the turbidity is about 0.2 NTU, and is collected into the water collection channel (26) through the filter tank water collection pipe (25), and flows into the clean water tank by gravity through the pipe (27). When the interception capacity of the filter material deteriorates, backwashing is automatically performed. The backwashing includes water backwashing and air-water backwashing. During water backwashing, the sewage is pumped through the sand washing tank (18) to the large siphon pipe (16) and the large siphon reducer (17) and discharged into the mud discharge area (23); during air-water backwashing, the water flushing continues, and the air flushing function is turned on, and the sewage enters the filter plate of the filter tank through the air pipe (29) of the Roots blower (28); Step 2: When the wind speed sensor detects that the amount of air entering the air inlet device (2801) is lower than the rated value, the first step air pump (2809) inputs current to generate compressed air, which is transported to the inside of the hollow column (2804) through the delivery pipe (2810) and the air chamber. The compressed air inside the hollow column (2804) drives the sealing plate (2806) to be in an open state through the spray gun port (2805), so that the compressed air can contact the surface of the filter device (2803) and perform a wind cleaning operation on the filter device (2803). The wind speed sensor monitors the amount of air entering the air inlet device (2801) in real time. When the amount of air entering is lower than the rated value, the second step of cleaning is performed. Step 3. When the second cleaning operation begins, the compressed air generated by the air pump (2809) is delivered to the interior of the U-shaped telescopic column (2808) through the micro-delivery tube, driving the U-shaped telescopic column (2808) to stretch, thereby driving the filter device (2803) to rotate ninety degrees. At the same time, the micro-vibration pump (2807) inputs current to drive the filter device (2803) to generate vibration force, driving the filter device (2803) to perform a secondary cleaning operation, thereby ensuring that the filter device (2803) can be thoroughly cleaned.
