Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to the Fenton reactor. Background Technology

[0002] Chinese patent document CN214360466U discloses a Fenton reactor, including a reaction vessel with a base at the bottom. A baffle plate is fixedly connected inside the reaction vessel, dividing it into upper and lower parts. A water inlet pipe and a dosing pipe A are connected to the reaction vessel located at the lower part of the baffle plate. A stirring blade is also provided inside the reaction vessel located at the lower part of the baffle plate. The stirring blade is driven by a drive motor located below the reaction vessel. The baffle plate is provided with nozzles connecting the upper and lower sides of the baffle plate. The baffle plate is filled with packing material. A water outlet weir is welded to the inner wall of the reaction vessel located above the packing material. A water outlet pipe is connected to the tank body of the reaction vessel located at the water outlet weir. A dosing pipe B is fixed at the top of the reaction vessel and inserted into the tank body.

[0003] However, in the aforementioned reactors, including some existing Fenton reactors, scale tends to accumulate on the surface of the wastewater filter media (such as iron-carbon particles) after long-term operation, leading to a decrease in mass transfer efficiency. Since the media usually adopts a fixed filling structure, it is difficult to effectively replace or regenerate it, causing the reactor performance to continuously decline with the extension of operating time, affecting the wastewater treatment effect and system stability. Therefore, we propose the Fenton reactor. Utility Model Content

[0004] The purpose of this invention is to provide a Fenton reactor that can solve the problem that the packing material in some existing Fenton reactors is difficult to replace, which leads to a gradual decrease in the reactor's wastewater treatment efficiency.

[0006] The reaction tower has a packing cylinder fixedly installed on its inner wall, and at least two sets of material discharge troughs are opened at the bottom of the packing cylinder;

[0007] The inlet mechanism, which is installed on the reaction tower, is used to divert wastewater.

[0008] The material discharge mechanism is located at the bottom of the packing cylinder. The material discharge mechanism includes a rotating plate, a material discharge hole, and a second water passage hole. The bottom of the packing cylinder is rotatably mounted with a rotating plate that fits against the bottom of the cylinder. The bottom of the rotating plate has at least two sets of material discharge holes and second water passage holes. Each set of second water passage holes is aligned with the corresponding material discharge trough, and each set of material discharge holes is staggered from the corresponding material discharge trough.

The other end of the inlet pipe extends to the bottom inner side of the reaction tower and is fixedly connected to the diversion network pipe, communicating with the interior of the diversion network pipe. At least two sets of outlet holes are provided on the diversion network pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The Fenton reactor, through the cooperation of the packing cylinder, the discharge chute and the plugging and discharging mechanism, can easily replace the iron and carbon particles in the packing cylinder when they are covered with scale and other impurities due to long-term use and seriously affect the performance of the reactor. This allows the reactor to maintain a high-efficiency and stable sewage treatment capacity for a long time, while reducing maintenance costs and improving the resource recycling rate. It solves the problem that in some existing Fenton reactors, the sewage filter packing, such as iron and carbon particles, is prone to scale deposits on the surface after long-term operation, which leads to a decrease in mass transfer efficiency. Since the packing usually adopts a fixed filling structure, it is difficult to effectively replace or regenerate it, which causes the reactor performance to continuously decline with the extension of the operating time, affecting the wastewater treatment effect and system stability. This improves the practicality of the reactor.

[0017] (2) The Fenton reactor, through the water inlet mechanism, can divert wastewater into the reaction tower through the diversion network and distribute it evenly from the bottom of the inner side of the reaction tower through various outlet holes. The structure is more novel than the existing diversion method. The purpose is to avoid uneven wastewater pollution caused by concentrated outflow in one place, which would result in uneven filtration of iron and carbon particles. This ensures the effectiveness of the reactor and is conducive to the promotion and use of the reactor. Attached Figure Description

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a Fenton reactor, including a reaction tower 1, a water inlet mechanism 5, and a plugging and discharging mechanism 4. A packing cylinder 2 is fixedly installed on the inner wall of the reaction tower 1. At least two sets of material drop troughs 3 are opened at the bottom of the packing cylinder 2. The water inlet mechanism 5 is set on the reaction tower 1 and is used to divert sewage. At least two sets of first water passage holes 6 are opened through the packing cylinder 2. A manhole communicating with the interior is opened on the outer surface of the reaction tower 1. A first cover 10 is detachably fixedly installed at the manhole. A guide plate 7 is fixedly installed on the inner wall of the reaction tower 1 and is mounted on the manhole. An outlet pipe 8 and an overflow pipe 9 communicating with the interior are fixedly installed on the outer surface of the reaction tower 1. A ladder 11 is fixedly installed on the outer surface of the reaction tower 1. A feeding port communicating with the interior is opened at the top of the reaction tower 1. A second cover 12 is detachably fixedly installed at the feeding port. A vent pipe 13 communicating with the interior is fixedly installed on the outer surface of the reaction tower 1.

[0026] The material blocking and discharge mechanism 4 is located at the bottom of the packing cylinder 2. The material blocking and discharge mechanism 4 includes a rotating plate 41, a material discharge hole 42, and a second water passage hole 43. The bottom of the packing cylinder 2 is rotatably mounted with a rotating plate 41 that fits against its bottom. The bottom of the rotating plate 41 has at least two sets of material discharge holes 42 and second water passage holes 43. Each set of second water passage holes 43 is aligned with the corresponding material discharge trough 3. Each set of material discharge holes 42 is staggered from the corresponding material discharge trough 3.

[0027] The plugging and discharging mechanism 4 also includes an L-shaped hanging plate 44, a waterproof motor 45, a gear 46, and an arc-shaped toothed plate 47. An L-shaped hanging plate 44 is fixedly installed on the outer surface of the packing cylinder 2. A waterproof motor 45 is fixedly installed at the bottom of the L-shaped hanging plate 44. A gear 46 is rotatably installed on the top of the L-shaped hanging plate 44. The shaft of the waterproof motor 45 is connected to the gear 46 for transmission. An arc-shaped toothed plate 47 is fixedly installed on the outer surface of the rotating plate 41. The gear 46 meshes with the arc-shaped toothed plate 47. Through the cooperation of the packing cylinder 2, the discharge chute 3, and the plugging and discharging mechanism 4, iron and carbon particles inside the packing cylinder 2 that have accumulated scale due to long-term use are blocked. When impurities severely affect reactor performance, the iron-carbon particles can be easily replaced, enabling the reactor to maintain a high-efficiency and stable wastewater treatment capacity for a long time. At the same time, it reduces maintenance costs and improves resource recycling rate. This solves the problem that in some existing Fenton reactors, the wastewater filter media such as iron-carbon particles are prone to scale buildup on the surface after long-term operation, leading to a decrease in mass transfer efficiency. Since the media usually adopts a fixed filling structure, it is difficult to effectively replace or regenerate, causing the reactor performance to continuously decline with the extension of operating time, affecting the wastewater treatment effect and system stability. This improves the practicality of the reactor.

[0028] The water inlet mechanism 5 includes an inlet pipe 51, a diversion network pipe 52, support rods 53, and outlet holes 54. The inlet pipe 51 is fixedly inserted through the reaction tower 1. One end of the inlet pipe 51 extends to the outside of the reaction tower 1. A diversion network pipe 52 is provided at the bottom inner side of the reaction tower 1. At least two sets of support rods 53 are fixedly installed between the diversion network pipe 52 and the bottom inner side of the reaction tower 1. The other end of the inlet pipe 51 extends to the bottom inner side of the reaction tower 1 and is fixedly connected to the diversion network pipe 52 and communicates with the inside of the diversion network pipe 52. At least two sets of outlet holes 54 are provided on the diversion network pipe 52. Through the water inlet mechanism 5, when sewage enters the reaction tower 1 through the inlet pipe 51, it can be diverted through the diversion network pipe 52 and flow out evenly from the bottom inner side of the reaction tower 1 through each outlet hole 54. This avoids the sewage from flowing out in one place and causing uneven pollution and uneven filtration of iron and carbon particles, thus ensuring the effectiveness of the reactor and facilitating its promotion and use.

[0029] Working principle: The packing cylinder 2 is filled with iron-carbon particles with a particle size larger than the apertures of the first water passage hole 6 and the second water passage hole 43, but smaller than the size of the discharge trough 3 and the discharge hole 42. During sewage treatment, sewage enters through the inlet pipe 51, is diverted by the diversion network pipe 52, flows out from each outlet hole 54 and accumulates, passes through the first water passage hole 6 and the second water passage hole 43, is filtered by the iron-carbon particles in the packing cylinder 2, and finally flows out from the outlet pipe 8. After long-term use, when the iron-carbon particles need to be replaced, Open the venting pipe 13 to vent the reaction tower 1, open the first cover 10, and start the waterproof motor 45. The waterproof motor 45 drives the gear 46 to rotate, and the gear 46 drives the arc-shaped toothed plate 47 and the rotating plate 41 to rotate, so that each material discharge hole 42 is aligned with the material discharge trough 3. The iron and carbon particles fall through the material discharge trough 3 and the material discharge hole 42, fall onto the guide plate 7, and are discharged from the reaction tower 1 through the manhole. After completion, drive the rotating plate 41 to reset, then open the second cover 12 and fill the packing cylinder 2 with new iron and carbon particles.
