Description

Technical Field

[0001] The utility model relates to an integrated V-shaped precipitation reactor, belonging to the technical field of sewage treatment. Background Art

[0002] Sedimentation is one of the main processes in sewage treatment. Sewage enters the sedimentation device, where the sludge or suspended matter is separated from the water to obtain clean water.

[0003] Existing sedimentation tanks are usually designed with various forms of sedimentation devices based on the shallow tank theory. Inclined plate sedimentation tank is one of the most representative sedimentation tanks. When in use, sewage enters the sedimentation tank from the inlet at the bottom of the sedimentation tank. When passing through the gaps between the inclined plate devices, the sludge (sediment) settles and falls to the bottom of the tank along the inclined plates, and is discharged through the pipes connected at the bottom, and the clean water is discharged from the top of the inclined plate device.

[0004] Since the water inflow and sediment deposition directions are opposite, on the one hand, the existing inclined plate sedimentation tank can only control the water inflow velocity at a slow speed, and has poor load impact resistance. The inclined plate is easily blocked by mud. Once the water flow is too large, it is easy to disturb the sediment, resulting in secondary water pollution. On the other hand, most of the mud discharge systems of the existing inclined plate sedimentation tank are located inside the system, and incomplete discharge causes sediment accumulation.

[0005] Therefore, it is urgent to propose a new integrated V-shaped precipitation reactor to solve the above technical problems. Utility Model Content

[0006] The purpose of developing this utility model is to solve the problems of poor sewage sedimentation effect, easy secondary pollution, large floor space, complex construction, long construction period, large investment, and dead corners for sediment discharge in traditional inclined plate sedimentation tanks.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection (i.e., non-detachable connection) includes but is not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection, and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection, and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: welding connection is selected for fixed connection, and hinge connection is selected for detachable connection.

[0028] Specific implementation method one: Combined with Figures 1-6 to illustrate this implementation method, an integrated V-type sedimentation reactor of this implementation method includes a sedimentation reactor body 1, an inlet baffle 2, a lower mud discharge pipe 3, a middle mud discharge pipe 5, an outlet pipe 7, an inclined plate filling area 9, a middle mud collecting trough 11 and a bottom mud collecting trough 12. A water inlet baffle 2 is installed on one side wall inside the sedimentation reactor body 1, and a uniform flow distribution diversion channel 16 is formed between the water inlet baffle 2 and the inner side wall of the sedimentation reactor body 1. The bottom of the sedimentation reactor body 1 is set as a bottom mud collecting trough 12, and the bottom mud collecting trough 12 is connected to the lower mud discharge pipe 3. The middle part of the sedimentation reactor body 1 is set as a middle mud collecting trough 11, and the middle mud collecting trough 11 is connected to the middle mud discharge pipe 5. The upper part of the sedimentation reactor body 1 is connected to the outlet pipe 7, and an inclined plate filling area 9 is set between the middle mud collecting trough 11 and the outlet pipe 7.

[0029] As the water level rises, the sewage flows into the uniform flow water distribution channel 16 between the baffle plate 2 and the reactor body 1 by gravity, and flows evenly into the bottom of the sedimentation reactor body 1 through the baffle plate 2, without splashing water, thus avoiding secondary pollution to the water body.

[0030] The middle and below of the sedimentation reactor body 1 are arranged with a V-shaped groove. The sedimentation reactor body 1 is formed by welding / assembling a combination of steel plates, and is coated with three coats of industrial-grade underwater special anti-corrosion paint inside and outside. The overall design is beautiful and durable. The reactor is placed underwater for use without affecting the flow of surrounding sewage.

[0031] A reactor support structure 10 is installed on the outside of the precipitation reactor body 1, and a water-passing plate 8 is installed at the bottom of the precipitation reactor body 1. The precipitation reactor body 1 can be placed in a conventional biochemical process system steel concrete tank body, with grid-like grid frames on both sides reinforcing the support structure 10 as support, and a water-passing plate 8 with holes at the bottom as support, which is used to stably support the precipitation reactor body 1.

[0032] The middle mud collecting trough 11 is communicated with the middle mud discharge pipe 5 through the middle mud discharge riser 4 .

[0033] The upper part of the precipitation reactor body 1 is connected to the outlet pipe 7 through the outlet triangular weir 6.

[0034] It also includes an ultrasonic mud-water interface meter 13, an automatic mud discharge valve 14 and an automatic control system 15. The automatic mud discharge valve 14 is installed on the lower mud discharge pipe 3. The ultrasonic mud-water interface meter 13 and the automatic mud discharge valve 14 are electrically connected to the automatic control system 15. The ultrasonic mud-water interface meter 13 detects and monitors the height of the sludge layer in the sedimentation reactor body 1, and sends a signal to the automatic control system 15. The automatic control system 15 controls the automatic mud discharge valve 14 to open or close. That is, when the mud discharge conditions and parameters are met, the ultrasonic mud-water interface meter 13 feeds back a signal to the automatic control system 15. The automatic control system 15 controls the automatic mud discharge valve 14 to open. The mud discharge valve can flow out to the sludge pool, or part of the sludge can flow back to the front-end biochemical pool, thereby improving the sewage treatment efficiency and reducing the treatment cost.

[0035] The inclined plate filler area 9 is assembled into an integrated inclined plate filler structure, which does not require hot-melt welding and nailing. It adopts high-strength new inclined plate material and is spliced ​​and combined with high strength. It can carry a load of 1 ton per square meter, thus solving the problem of filler collapse.

[0036] The mixed sewage flows uniformly into the bottom of the sedimentation reactor body 1 through the uniform flow distribution channel 16, and then moves upward uniformly in the plane of the sedimentation reactor body 1. The sludge or SS suspended particles in the mixed sewage are precipitated in the inclined plate filling area 9, the middle mud collecting tank 11 and the bottom mud collecting tank 12 under the action of gravity. The supernatant precipitated from the mixed sewage continues to flow upward and passes through the inclined plate filling area 9. Then, it flows to the outlet pipe 7 through the outlet triangular weir 6 on one side of the top of the outlet triangular weir 6, and finally flows out from the outlet pipe 7 into the next unit;

[0037] Solid-liquid separation is performed by sedimentation, and the sludge or SS suspended particles precipitated from the mixed sewage are precipitated in the middle sludge collecting tank 11 and the bottom sludge collecting tank 12; as time goes by, more and more sludge or SS in the middle sludge collecting tank 11 and the bottom sludge collecting tank 12 are precipitated to form a thick sludge layer, and the height of the sludge layer is monitored in real time by an ultrasonic mud-water interface meter 13 arranged on the top of the sedimentation reactor body 1;

[0038] When the ultrasonic mud-water interface meter 13 detects that the height of the sludge layer reaches the sludge discharge conditions and parameters, the ultrasonic mud-water interface meter 13 feeds back a signal to the automatic control system 15, and the automatic control system 15 controls the automatic mud discharge valve 14 to open, and the sludge is discharged through the lower mud discharge pipe 3 at the bottom of the tank. At the same time, the sludge in the middle mud collecting tank 11 flows to the bottom through the middle mud discharge riser 4 on both sides of the middle mud discharge riser 4, and is discharged after being merged into the middle mud discharge pipe 5. The sludge is discharged in layers without causing sludge deposition and blockage.

[0039] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined, and those skilled in the art can exhaust all possibilities based on the mathematical knowledge of arrangement and combination. Therefore, the present utility model will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present utility model.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
