Description
Technical Field
[0001] This utility model belongs to the technical field of water treatment devices, and relates to a gravity clarifier with a multi-stage honeycomb flow guiding device. Background Technology
[0002] In the pretreatment process of water treatment, the clarification tank is a crucial component. It is not only the first critical step in the entire water treatment process but also plays a vital role in ensuring the effectiveness of subsequent treatments and the safe operation of equipment. The pretreatment process not only protects downstream treatment equipment, regulates water quality and quantity, removes some pollutants, and improves overall treatment efficiency, but also brings long-term economic benefits. Therefore, the pretreatment stage should be given high priority in the design and operation management of water treatment systems to ensure its effective operation.
[0003] To address this issue, a gravity clarifier with a multi-stage honeycomb flow guiding device was designed to overcome the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a gravity clarifier with a multi-stage honeycomb flow guiding device that is simple and reasonable in structure, easy to install and maintain, stable in operation, and safe and reliable. The gravity clarifier designed in this invention can effectively solve the problem of high turbidity in effluent caused by unstable river water quality during the use of existing gravity clarifiers, thus upgrading the equipment.
[0005] This utility model is achieved through the following technical solution: a gravity clarifier with a multi-stage honeycomb flow guiding device, comprising a gravity clarifier and a multi-stage honeycomb flow guiding device disposed within the gravity clarifier. The bottom area of the gravity clarifier is smaller than its top area, and it has an overall funnel-shaped structure. The bottom of the gravity clarifier is supported by multiple support columns. A water inlet pipe is disposed on one side of the bottom of the gravity clarifier, one end of which extends into the gravity clarifier. A water inlet nozzle is installed at its end, and it is connected to a first reaction chamber disposed in the middle of the water inlet pipe through a throat pipe. A booster pump is installed at the other end of the pipe. The booster pump transports the turbid water along the inlet pipe to the first reaction chamber. After filling the entire first reaction chamber, the water overflows into the gravity clarifier and then fills the entire gravity clarifier. A cleaning device is installed at the bottom of the gravity clarifier to remove the sludge accumulated at the bottom of the gravity clarifier. A multi-stage honeycomb flow guiding device is also installed at the top of the gravity clarifier to purify the turbid water in the gravity clarifier. The purified water is then transported to a valveless filter for further treatment through an outlet channel at the top of the gravity clarifier.
[0006] Preferably, the multi-stage honeycomb flow guiding device consists of small-pitch inclined plates and honeycomb inclined tubes arranged vertically. Both the small-pitch inclined plates and the honeycomb inclined tubes are annular structures with the same cross-section. The small-pitch inclined plates are positioned directly above the honeycomb inclined tubes, with their bottom surfaces connected to the top surfaces of the honeycomb inclined tubes, forming an integrated annular structure of a secondary honeycomb flow guiding plate. The outer ring of this annular secondary honeycomb flow guiding plate is fixed to the inner wall of the gravity clarifier near the top, and an annular baffle is fixed on the inner ring to ensure that turbid water passes sequentially from the bottom of the honeycomb inclined tubes through the honeycomb inclined tubes and the small-pitch inclined plates for purification. A water outlet trough is provided directly above the small-pitch inclined plates at a position near the top of the gravity clarifier. The water outlet trough is connected to a valveless filter via an external pipe to transport the purified water to the valveless filter.
[0007] Preferably, the number of small-pitch inclined plates and honeycomb inclined tubes is multiple sets, which are alternately spliced together to form a multi-level honeycomb guide plate with an integrated ring structure, in order to ensure the purification effect.
[0008] Preferably, the cleaning device consists of a sludge discharge hopper and a sewage discharge pipe. The sludge discharge hopper is installed on one side of the bottom of the gravity clarifier and / or in the middle of the bottom of the gravity clarifier. A sewage discharge pipe with a sewage pump and valve is connected directly below the sludge discharge hopper. The sewage discharge pipe receives a collection and treatment device. By turning on the sewage pump, the sludge accumulated in the middle of the bottom of the gravity clarifier is discharged and sent to the collection and treatment device for unified collection and treatment.
[0009] Preferably, the lower surface area of the first reaction chamber is smaller than the upper surface area, so that the longitudinal section of the first reaction chamber has an inverted trapezoidal structure. The height of the upper surface of the first reaction chamber is higher than the bottom surface height of the small-pitch inclined plate, and the height of the lower surface of the first reaction chamber is lower than the bottom surface height of the honeycomb inclined tube, in order to ensure the flow direction of turbid water.
[0010] The beneficial effects of this utility model are as follows: The gravity clarifier with a multi-stage honeycomb flow guiding device designed in this utility model can filter and purify turbid water multiple times through the designed small-pitch inclined plates and honeycomb inclined tubes, ensuring that the turbidity of the original clarifier effluent is 10 NTU, reducing it to 2-5 NTU; then the water is transported from the drainage channel to a valveless filter (water purification and desalination system) for further treatment, reducing the impact on the subsequent water purification and desalination system and improving the water production capacity of the subsequent water purification system.

[0015] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-2 As shown, a gravity clarifier with a multi-stage honeycomb flow guiding device includes a gravity clarifier 1 and a multi-stage honeycomb flow guiding device installed inside the gravity clarifier. The bottom area of the gravity clarifier 1 is smaller than the top area, and the overall structure is funnel-shaped. The bottom of the gravity clarifier 1 is supported by multiple support columns 2. A water inlet pipe 3 is provided on one side of the bottom of the gravity clarifier 1. One end of the water inlet pipe 3 extends into the gravity clarifier 1, and a water inlet nozzle 4 is installed at its end. The nozzle 4 is connected to a first reaction chamber 6 located in the middle of the water inlet pipe 3 through a throat pipe 5. A booster pump is installed at the other end of the water inlet pipe 3. 7. Turbid water is pumped through the booster pump 7 along the inlet pipe 3 to the first reaction chamber 6. After filling the first reaction chamber 6, it overflows into the gravity clarifier 1 and fills the entire gravity clarifier 1. A cleaning device is installed at the bottom of the gravity clarifier 1 to remove the sludge accumulated at the bottom of the gravity clarifier 1. A multi-stage honeycomb flow guiding device is also installed at the top of the gravity clarifier 1 to purify the turbid water in the gravity clarifier 1. Then, it is pumped through the outlet trough 8 at the top of the gravity clarifier 1 to the valveless filter (not shown in the figure) for further processing.
[0016] The multi-stage honeycomb flow guiding device consists of small-pitch inclined plates 9 and honeycomb inclined tubes 10 arranged vertically. Both the small-pitch inclined plates 9 and the honeycomb inclined tubes 10 are annular structures with the same cross-section. The small-pitch inclined plates 9 are located directly above the honeycomb inclined tubes 10, and their bottom surfaces are connected to the top surfaces of the honeycomb inclined tubes 10, forming an integrated annular structure of a secondary honeycomb flow guiding plate. The outer ring of this annular structure of the secondary honeycomb flow guiding plate is fixed to the inner wall of the gravity clarifier 1 near the top. An annular baffle is fixed on the inner ring to ensure that the turbid water passes through the honeycomb inclined tubes 10 and the small-pitch inclined plates 9 sequentially from the bottom of the honeycomb inclined tubes 10 for purification. A ring of water outlet troughs 8 is set directly above the small-pitch inclined plates 9 near the top of the gravity clarifier 1. The water outlet troughs 8 are connected to the valveless filter through an external pipe to transport the purified water to the valveless filter.
[0017] The number of small-pitch inclined plates 9 and honeycomb inclined tubes 10 is multiple sets, which are alternately spliced together to form a multi-level honeycomb guide plate with an integrated ring structure to ensure the purification effect.
[0018] The cleaning device consists of a sludge discharge hopper 11 and a sewage discharge pipe 12. The sludge discharge hopper 11 is installed on one side of the bottom of the gravity clarifier 1 and / or installed in the middle of the bottom of the gravity clarifier 1. The sewage discharge pipe 12 with a sewage pump 13 and a valve 15 is connected directly below the sludge discharge hopper 11. The sewage discharge pipe 12 receives a collection and treatment device 14. By turning on the sewage pump 13, the sludge accumulated in the middle of the bottom of the gravity clarifier 1 is discharged and sent to the collection and treatment device 14 for unified collection and treatment.
[0019] The lower surface area of the first reaction chamber 6 is smaller than the upper surface area, making the longitudinal section of the first reaction chamber 6 an inverted trapezoidal structure. The height of the upper surface of the first reaction chamber 6 is higher than the bottom surface height of the small-pitch inclined plate 9, and the height of the lower surface of the first reaction chamber 6 is lower than the bottom surface height of the honeycomb inclined tube 10, in order to ensure the flow direction of turbid water.
[0020] This invention relates to a gravity clarifier with a multi-stage honeycomb flow guiding device. The gravity clarifier incorporates two (or more) stages of honeycomb flow guiding devices. The first stage, honeycomb-shaped inclined tubes, creates a 60° angle between the water surface and the sedimentation tank. Numerous honeycomb-shaped inclined tubes allow water to flow from bottom to top, causing particles to settle to the bottom and slide down automatically. This significantly reduces the hydraulic radius of the sedimentation tank, resulting in a substantial decrease in the Reynolds number R and a significant increase in the Froude number, thus satisfying both flow stability and laminar flow requirements. The second stage uses small-pitch inclined plates to further improve sedimentation efficiency and reduce effluent turbidity. The effluent turbidity of the gravity clarifier is reduced from 10 NTU to a stable 2-5 NTU.
[0021] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
