Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a high-efficiency and energy-saving ultraviolet disinfection device for sewage. Background Technology

[0002] In the field of wastewater treatment, disinfection is a key process to ensure water quality safety. Ultraviolet (UV) disinfection technology is widely used in various wastewater treatment scenarios due to its advantages such as no need to add chemical agents, no secondary pollution, and high sterilization efficiency. However, current traditional UV disinfection methods have significant technical limitations and cannot meet the needs of efficient and thorough disinfection. Traditional ultraviolet (UV) disinfection devices typically employ a design where UV lamps are installed at the top of the wastewater treatment tank, irradiating the water from top to bottom with UV light. However, this layout has fundamental flaws: Firstly, wastewater often contains suspended particulate matter, colloidal substances, and organic matter, which scatter and absorb UV light, limiting its penetration depth and making it difficult to effectively reach the lower and deeper parts of the tank, creating disinfection blind spots. Secondly, as treatment time progresses, sludge and pollutants tend to accumulate at the bottom of the tank, preventing sufficient irradiation by the upper UV light. This makes it difficult to completely inactivate microorganisms in these areas, affecting the overall disinfection effect and increasing the risk of effluent exceeding standards. To address these issues, the industry has attempted to increase irradiation intensity by increasing the power or number of UV lamps. However, this not only significantly increases equipment energy consumption and operating costs but also shortens lifespan due to increased lamp heating, which contradicts the current trend of energy conservation and environmental protection. Therefore, an immersion-type UV disinfection device was designed. By inserting UV lamps into wastewater, it achieves UV sterilization treatment of the wastewater at the bottom, thereby improving the sterilization effect. Utility Model Content

[0003] The purpose of this invention is to provide a highly efficient and energy-saving wastewater ultraviolet disinfection device. By inserting an ultraviolet lamp into the wastewater, ultraviolet sterilization treatment is achieved on the wastewater at the bottom, thereby improving the sterilization effect.

[0004] The technical implementation scheme of this utility model is as follows: A high-efficiency and energy-saving wastewater ultraviolet disinfection device includes a pool body, a first guide channel, a first disinfection mechanism, and a second disinfection mechanism. The pool body is a rectangular cavity structure with an open top, and the first guide channel is provided inside the pool body. The first disinfection mechanism and the second disinfection mechanism are provided inside the first guide channel. The first disinfection mechanism includes a water guide channel, a filter tank, a first water guide pipe, and a first ultraviolet lamp. The filter tank is provided inside the water guide channel, and the first water guide pipe is provided at the bottom of the filter tank. Several second water guide pipes are provided inside the first water guide pipe, and the first ultraviolet lamp is provided on the outer wall of the first water guide pipe. The water guide channel is set on the water inlet of the pool body by screws, and the second disinfection mechanism is provided at one end of the water guide channel.

[0005] Optionally, the second water guide pipe is connected to the inner wall of the first water guide pipe via a connecting ring.

[0006] Optionally, the first ultraviolet lamp is mounted on the outer wall of the first water pipe via a connecting bracket.

[0007] Optionally, the second disinfection mechanism includes a fixed bracket, a connecting slide, a second ultraviolet lamp, and a protective cover.

Several second ultraviolet lamps are provided on the connecting plate, and a protective cover is provided outside the second ultraviolet lamps.

[0008] Optionally, the fixed bracket is connected to the connecting groove on the pool body via connecting slides on both sides.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figures 1-8 As shown, a high-efficiency and energy-saving ultraviolet disinfection device for sewage includes a tank body 1, a first guide channel 2, a first disinfection mechanism 5, and a second disinfection mechanism 4. The tank body 1 is a rectangular cavity structure with an opening at the top, and the first guide channel 2 is provided inside the tank body 1. The first disinfection mechanism 5 and the second disinfection mechanism 4 are arranged inside the first guide channel 2. The first disinfection mechanism 5 includes a water guiding channel 501, a filter tank 503, a first water guiding pipe 509, and a first ultraviolet lamp 506. The filter tank 503 is provided inside the water guiding channel 501. A first water guide pipe 509 is provided at the bottom of the 3, and several second water guide pipes 510 are provided inside the first water guide pipe 509. A first ultraviolet lamp 506 is provided on the outer wall of the first water guide pipe 509. A water guide channel 501 is set on the water inlet 8 of the pool body 1 by screws, and a second disinfection mechanism 4 is provided at one end of the water guide channel 501. The second water guide pipes 510 are connected to the inner wall of the first water guide pipe 509 by connecting rings. The first ultraviolet lamp 506 is set on the outer wall of the first water guide pipe 509 by connecting bracket 505.

[0025] It should be noted that a first guide channel 2 is provided inside the pool body 1. The first guide channel 2 is equipped with a first disinfection mechanism 5 and a second disinfection mechanism 4, which can realize two disinfection operations on the water source, effectively improving the thoroughness and reliability of disinfection. The first disinfection operation is completed during the water intake process, and the specific procedure is as follows: The water source first enters the filter tank 503, and is filtered by the filter screen 504 inside the tank to remove impurities and particulate matter, laying a good foundation for the subsequent disinfection operation; the filtered water source then flows into the first water guide pipe 509, and then is divided and guided through the second water guide pipe 510. This divided and guided flow design can disperse the concentrated water flow into multiple tributaries, making the water flow distribution in the water guide pipe more uniform and avoiding situations where the water flow is too dense or too sparse in some areas. At the same time, the first ultraviolet lamp 506 on the outer wall of the first water guide pipe 509 is activated and performs disinfection. As the water flow is evenly distributed after being differentiated and guided, each stream of water can fully come into contact with the ultraviolet rays emitted by the first ultraviolet lamp 506, which greatly increases the contact area and contact time between the water flow and the ultraviolet rays, thereby improving the killing efficiency of ultraviolet rays on bacteria, viruses and other microorganisms in the water, and ensuring that the first disinfection operation can effectively reduce the content of microorganisms in the water.

[0026] like Figures 1-8As shown, the second disinfection mechanism 4 includes a fixed bracket 401, a connecting slide bar 403, a second ultraviolet lamp 404, and a protective cover 405. The fixed bracket 401 has several rectangular openings, and a connecting plate 402 is provided inside each rectangular opening. Several second ultraviolet lamps 404 are provided on the connecting plate 402, and a protective cover 405 is provided outside each second ultraviolet lamp 404. The fixed bracket 401 is connected to the connecting slide groove on the pool body 1 through the connecting slide bars 403 on both sides. The fixed bracket 401 forms multiple flow guiding structures through the protective cover 405 at the bottom.

[0027] It should be noted that the second disinfection mechanism 4 is set up to realize the second disinfection operation. The connecting plate 402 of the fixed bracket 401 is equipped with several second ultraviolet lamps 404, and the outer side of the second ultraviolet lamps 404 is covered with protective covers 405. Multiple protective covers extend into the interior of the first guide channel 2, forming guide channels with each other. Sewage can flow through the guide channels and then be sterilized by the second ultraviolet lamps 404 on both sides, thereby improving the sterilization effect.

[0028] It should be further explained that the protective cover 405 can be set as an S-shaped structure to extend the distance the water flows in the guide channel, so that it can be fully irradiated by the ultraviolet lamps on both sides, thereby carrying out sterilization.

[0029] like Figures 1-6 As shown, the interior of the pool body 1 is provided with several second flow channels 7, and the upper part of the pool body 1 is provided with a carrier plate 6; the upper part of the pool body 1 is provided with a protective railing 3.

[0030] It should be noted that the purpose of having several second guide channels 7 inside the pool is to accelerate the flow of water. The bottom of the second guide channels 7 is inclined, which can accelerate the flow of sterilized water and prevent the accumulation of particles inside.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
