Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, particularly the field of clarification device technology, specifically a high-density clarification device. Background Technology

[0002] A clarification device is a water treatment equipment. Its main technical principle utilizes the contact flocculation effect of an activated sludge layer to trap impurities in the raw water, thus achieving water clarification. Clarification devices are primarily used to remove suspended solids and colloidal impurities from water. The clarification process involves three stages: water coagulation, reaction, and separation of the flocs from the water. In the clarification device, raw water flows from bottom to top, passing through the sludge suspension layer. The contact flocculation principle removes suspended solids and colloids from the water. However, existing clarification devices suffer from problems such as short reaction times and inability to adapt to fluctuations in the quality and quantity of raw water. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an optimized high-density clarification device that ensures sufficient contact and collision of raw water after chemical addition within the clarification device, which is beneficial for the flocculation and sedimentation effect of low-temperature and low-turbidity water, improves flocculation and mud-water separation efficiency, and effectively reduces the turbidity of the effluent from the clarification device.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a high-density clarification device, comprising a clarification device body and an inclined tube, a reaction tank is provided inside the clarification device body, and a water inlet pipe is connected to the reaction tank, and a return pipe is connected to the water inlet pipe, a water distributor is provided around the reaction tank, and a flow guide cone is provided inside the clarification device body;

[0005] The main body of the clarification device has a water collection tank at the top, and a water outlet pipe is connected to the side of the water collection tank. The bottom of the main body of the clarification device is equipped with a sludge collection hopper, and a sludge discharge and emptying pipe is connected to the side of the sludge collection hopper.

[0006] In a preferred embodiment of the high-density clarification device described in this utility model, the inlet pipe and the return pipe are respectively provided with corresponding valves;

[0007] The valves at the corresponding positions are used to control the opening and closing of the inlet pipe and the return pipe.

[0008] In a preferred embodiment of the high-density clarification device described in this utility model, the angle between the slope of the guide cone and the horizontal line is between 45 and 65 degrees.

[0009] In a preferred embodiment of the high-density clarification device described in this utility model, the sludge at the bottom of the main tank of the clarification device is concentrated in the area of ​​the sludge collection hopper, and the sludge is discharged through the sludge discharge and drainage pipe.

[0010] In a preferred embodiment of the high-density clarification device described in this utility model, the semi-finished water collected in the water collection tank is discharged through the water outlet pipe.

[0011] In a preferred embodiment of the high-density clarification device described in this utility model, after the raw water enters the clarification device, it is distributed by a water distributor, which increases the probability of contact and collision between particles.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] The clarification device was optimized to ensure that the raw water, after chemical addition, is distributed within the device via a water distributor. This increases the probability of contact and collision between particles, prolongs the time for unidirectional flocculation, and improves the flocculation and sedimentation effect of low-temperature, low-turbidity water. A figure-eight shaped guide cone was installed in the clarification device to separate the rising water flow from the sludge settling path, improving sludge-water separation efficiency and effectively reducing the turbidity of the effluent from the clarification device.

[0014] In practical use, raw water enters the reaction tank through the inlet pipe for flocculation. When the raw water turbidity is low, sludge is returned through the return pipe to mix with the raw water, increasing the concentration of suspended solids and thus increasing the collision probability of flocculation. Water distributors are installed around the reaction tank to ensure uniform water flow and contact and collision under the action of swirling inertia, thereby causing volumetric flocculation and effectively extending the unidirectional flocculation time. Initial particles in the water undergo multiple collisions as they rise along the water flow under the guide cone, forming dense flocculent particles. Under the obstruction of the guide cone and the action of gravity, the dense flocculent particles settle to the bottom of the tank, achieving better separation from the water. Some flocculated particles enter the upper part of the guide cone and settle after being separated by the inclined tube. The settled sludge also settles due to the angle between the slope of the guide cone and the horizontal line being between 45 and 65 degrees, which facilitates the sludge to slide down and settle. It is collected by the sludge hopper to the bottom of the pool. The semi-finished clear water enters the water collection area, is collected by the water collection trough, and is discharged through the water outlet pipe. The sludge at the bottom of the high-density clarification device is discharged through the sludge discharge and emptying pipe. Attached Figure Description

[0024] This invention provides an optimized high-density clarification device that ensures sufficient contact and collision of raw water after chemical addition within the clarification device, which is beneficial for the flocculation and sedimentation effect of low-temperature, low-turbidity water, improves flocculation and mud-water separation efficiency, and can effectively reduce the turbidity of the effluent from the clarification device.

[0026] A water collection trough 7 is located above the main body 11 of the clarification device, and a water outlet pipe 8 is connected to the side of the water collection trough 7. A mud collection hopper 10 is provided at the bottom of the main body 11 of the clarification device, and a mud discharge pipe 9 is connected to the side of the mud collection hopper 10.

[0027] In practical use, raw water enters the reaction tank 3 through the inlet pipe 1 for flocculation. When the raw water turbidity is low, the sludge is returned through the return pipe 2 to mix with the raw water, improving the flocculation effect. Water distributors 4 are installed around the reaction tank 3 to ensure uniform water distribution and contact and collision under the action of swirling inertia, thus causing volumetric flocculation and effectively extending the time of unidirectional flocculation.

Under the obstruction of the guide cone 5 and the action of gravity, the dense flocculent particles settle to the bottom of the tank, achieving better separation from the water. The sludge that slides down after being separated by the inclined tube 6 is also facilitated by the slope of the guide cone 5 and the horizontal line, which is between 45 and 65 degrees, so that the sludge can be collected by the sludge collection hopper 10 to the bottom of the pool. The semi-finished clear water enters the water collection area, is collected by the water collection trough 7, and is discharged by the water outlet pipe 8. The sludge at the bottom of the high-density clarification device is discharged through the sludge discharge and emptying pipe 9.
