Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency Fenton fluidized bed wastewater treatment device. Background Technology

[0002] The reaction tower in Fenton fluidized bed wastewater treatment is a key piece of equipment for realizing the Fenton reaction. The Fenton reaction utilizes iron ions (Fe²⁺) as a catalyst and hydrogen peroxide (H₂O₂) as an oxidant to generate highly oxidizing hydroxyl radicals (·OH) under acidic conditions. These radicals can effectively degrade organic pollutants in wastewater, thus providing a suitable environment for the reaction and ensuring the effective degradation of organic pollutants. The design and structure of this type of reaction tower directly affect the reaction efficiency and typically includes the tower body, feed system, discharge system, and monitoring instruments. The tower body is generally cylindrical and made of materials with good corrosion resistance. The feed system is responsible for uniformly introducing wastewater into the reaction tower to ensure thorough mixing of the reactants, while the discharge system is responsible for effectively discharging the wastewater and gases after the reaction.

[0003] For example, a novel Fenton fluidized bed device disclosed in application publication number CN114455688A includes a reactor tank. The bottom of the reactor tank is equipped with a V-shaped water distribution pipe for wastewater inlet and a high-speed jet dosing device. Multiple packing layers are arranged above the water distribution device and the high-speed jet dosing device. A circulating water inlet water distribution device is arranged in the middle of the packing layers. Baffles and a high-speed jet water distribution device are arranged at the top of the reactor tank. This device improves the mass transfer efficiency of hydroxyl radicals by employing multi-layer stacking, high-efficiency water distribution pipes, jet technology, and inclined baffles in wastewater treatment. There are issues such as physical defoaming. However, the current reaction tower is composed of several sections stacked one on top of another, which makes the tower quite tall. As a result, workers need to use the external ladders to climb to the top for maintenance and repair. There is no area for workers to rest on the outside of the tower during the climb. Workers need to remain on the ladder and keep stable while resting. However, staying on the ladder for a long time can easily lead to physical fatigue and increase the burden on the body. At this time, any slight imbalance or accident may lead to a fall, affecting the safety of the operation. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency Fenton fluidized bed wastewater treatment device. A staggered and continuous first-stage and second-stage guardrail-type climbing ladder is installed vertically on the outer wall of the reaction tower section. A first-stage polygonal suspension platform is installed between the first-stage and second-stage guardrail-type climbing ladders, and a second-stage polygonal suspension platform is set between the second-stage guardrail-type climbing ladder and the top plane of the reaction tower section, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency Fenton fluidized bed wastewater treatment device, comprising a reaction tower section and an inlet pipe and an outlet pipe respectively installed on the front and rear outer walls of one end of the reaction tower section. A primary guardrail-type climbing ladder is installed on one side of the outer wall of the reaction tower section, and a secondary guardrail-type climbing ladder is installed in a staggered and continuous manner on the outer wall of the reaction tower section above the primary guardrail-type climbing ladder. A primary polygonal suspension platform is installed on the outer wall of the reaction tower section between the top of the primary guardrail-type climbing ladder and the bottom of the secondary guardrail-type climbing ladder. A secondary polygonal suspension platform is installed on the outer wall of the reaction tower section outside the inlet pipe.

[0006] Preferably, the primary guardrail climbing ladder includes several vertical ladders welded and fixed to the outer wall of one side of the reaction tower section. The continuous extension line of the several vertical ladders is parallel to the vertical center line of the reaction tower section. The ends of the several vertical ladders away from the reaction tower section are jointly bolted with a support arm. Several uprights are installed at equal intervals in the vertical direction on the outer wall of the support arm.

[0007] Preferably, a protective cage is fixed between several of the uprights, and the protective cages are symmetrical about the center point of the uprights.

[0008] Preferably, the two-stage polygonal suspension platform consists of a lower side arm 1, a lower side arm 2, a square column, an upper side arm 1, an upper side arm 2, a support plate, and a support platform. The support plate is fixed to both ends of the surface of the square column. The lower side arm 1 and the lower side arm 2 are fixed to both sides of the top of one of the support plates. The upper side arm 1 and the upper side arm 2 are fixed to both sides of the top of the other support plate. The support platform is fixed to the upper surface of two adjacent vertical arms.

[0009] Preferably, a number of guardrails are installed at equal intervals between the lower side arm 1 and the upper side arm 2 in the vertical direction, as well as between the lower side arm 2 and the upper side arm 1 in the vertical direction.

[0010] Preferably, one of the support platforms has an arc-shaped groove on one outer wall for a secondary guardrail-type climbing ladder to pass through.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This high-efficiency Fenton fluidized bed wastewater treatment device, through the coordinated structure of a primary guardrail-type climbing ladder and a secondary polygonal suspension platform, provides multi-layered safety protection. The design of these guardrails effectively prevents workers from falling due to loss of balance during climbing, thereby significantly reducing the risk of working at heights. Furthermore, the primary polygonal suspension platform set between the primary and secondary guardrail-type climbing ladders is not only a transition platform for climbing but also provides workers with a safe rest and operating space. The presence of the suspension platform allows them to stop in time to recover their strength during tasks, improving the continuity and effectiveness of work, ensuring that workers can better complete maintenance and repair work. Moreover, when workers reach the top of the tower, they can directly perform equipment maintenance or monitoring on the secondary suspension platform without having to climb back up the ladder, making the entire maintenance process smoother and more efficient.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 An embodiment of this utility model provides: a high-efficiency Fenton fluidized bed wastewater treatment device, including a reaction tower section 1 and an inlet pipe 2 and an outlet pipe 3 respectively installed on the front and rear outer walls of one end of the reaction tower section 1. A first-level guardrail climbing ladder 4 is installed on one side of the outer wall of the reaction tower section 1, and a second-level guardrail climbing ladder 5 is installed in a staggered and continuous manner on the outer wall of the reaction tower section 1 above the first-level guardrail climbing ladder 4. A first-level polygonal suspension platform 6 is installed on the outer wall of the reaction tower section 1 between the top of the first-level guardrail climbing ladder 4 and the bottom of the second-level guardrail climbing ladder 5. A second-level polygonal suspension platform 7 is installed on the outer wall of the reaction tower section 1 outside the inlet pipe 2.

[0020] The first-level guardrail-type climbing ladder 4 includes several vertical ladders 402 welded and fixed to the outer wall of one side of the reaction tower section 1. The continuous extension line of the several vertical ladders 402 is parallel to the vertical center line of the reaction tower section 1. The ends of the several vertical ladders 402 away from the reaction tower section 1 are jointly bolted with a support arm 401. Several uprights 403 are installed at equal intervals in the vertical direction on the outer wall of the support arm 401. The design of the support arm 401 allows the vertical ladders 402 to be firmly fixed to the outer wall of the reaction tower section 1. It effectively distributes the vertical load, enhances the overall stability of the ladder, and avoids tilting caused by unstable center of gravity during climbing. The structural design of the vertical ladders 402 makes the climb more vertical for workers, reduces the need for lateral balance, and reduces the risk of falling.

[0021] A protective cage 404 is fixed between several uprights 403. The protective cages 404 are symmetrical about the center point of the uprights 403. The uprights 403 and the protective cages 404 surround the vertical tower ladder 402, which can effectively prevent workers from falling accidentally while climbing, provide a safety barrier, and make workers feel safer while climbing, so that they can focus more on the operation and reduce psychological burden.

[0022] The two-dimensional polygonal suspension platform 7 is composed of a lower side arm 1 701, a lower side arm 2 702, a square column 703, an upper side arm 1 704, an upper side arm 2 705, a support plate 706, and a support platform 708. The support plate 706 is fixed to both ends of the surface of the square column 703. The lower side arm 1 701 and the lower side arm 2 702 are fixed to both sides of the top of one of the support plates 706. The upper side arm 1 704 and the upper side arm 2 705 are fixed to both sides of the top of the other support plate 706. The support platform 708 is fixed to the upper surface of two adjacent longitudinal arms 709.

[0023] The main components of the two-dimensional polygonal suspension platform 7 are the lower side arm 1 701, the lower side arm 2 702, the square column 703, the upper side arm 1 704, and the upper side arm 2 705, which constitute the frame of the platform and form the outer guardrail. The guardrail 707 connects the lower side arm 1 701, the upper side arm 2 705, the lower side arm 2 702, and the upper side arm 1 704, thereby strengthening the guardrail structure. Its multi-support design can effectively distribute the load, reduce the risk of excessive stress on a single support point, and reduce the possibility of tilting or collapse.

[0024] Several guardrails 707 are installed at equal intervals between the lower side arm 701 and the upper side arm 705 in the vertical direction, as well as between the lower side arm 702 and the upper side arm 704 in the vertical direction. The guardrails 707 and the support plate 706 connect each side arm to the column. The operator can expand or shrink in multiple directions according to actual needs, so that the two-dimensional polygonal suspension platform can be easily adjusted and expanded to cover different working areas.

[0025] One of the support platforms 708 has an arc-shaped groove on one outer wall for the secondary guardrail climbing ladder 5 to pass through. Operators can place the necessary tools and materials on the support platform 708 at the same time, avoiding the process of frequently going up and down, making the operation safer.

[0026] In this embodiment, during use, the worker first wears personal protective equipment, such as a helmet, safety belt, gloves, and non-slip shoes, to minimize the risk of accidental injury during climbing. The safety of the climbing ladder and suspension platform is then checked to ensure there is no obvious damage or slippage. The worker then begins climbing to the top of the first-level guardrail-type climbing ladder 4, which provides a stable climbing environment. If rest is needed, a short stop can be made at a point on the first-level guardrail-type climbing ladder 4, using the guardrail for support and to relieve fatigue. When the worker reaches the top of the first-level guardrail-type climbing ladder 4, they will arrive at the first-level polygonal platform. The first-stage polygonal suspension platform 6 serves as a transition platform. On this platform, one must first ensure a stable footing and then observe the surrounding equipment to prepare for the next step of the operation. Tools or materials can also be placed on this platform to ensure convenience when working at height. Then, one continues to hold onto the guardrail of the second-stage guardrail climbing ladder 5 and gradually climbs up. When the workers successfully climb to the top of the second-stage guardrail climbing ladder 5, they will reach the second-stage polygonal suspension platform 7. Using this platform, workers can directly perform maintenance and inspection of the reaction tower section 1 without having to climb back up, thus reducing the complexity of the operation.
