Description

Technical Field

[0001] This utility model relates to the field of tunnel ventilation and purification technology, and more specifically, to a novel ventilation and purification system for highway tunnels. Background Technology

[0002] New-type highway tunnels refer to modern tunnels that employ more advanced designs, materials, or technologies. One of their core objectives is to improve operational safety and environmental protection. As a relatively enclosed space, a tunnel continuously accumulates pollutants composed of vehicle exhaust fumes (such as carbon monoxide, nitrogen oxides, and hydrocarbon particulate matter). Therefore, an effective ventilation and purification system is crucial: ventilation ensures air circulation within the tunnel, providing basic protection for the lives of drivers and passengers, and ensuring visibility meets driving safety requirements; while purification aims to deeply treat these harmful pollutants to reduce the impact of tunnel emissions on the surrounding atmospheric environment and meet increasingly stringent environmental regulations.

[0003] However, existing tunnel purification systems have some problems: 1. The short purification process in tunnel purification systems leads to insufficient contact between air and purification materials, resulting in incomplete purification; 2. The lack of real-time monitoring and reprocessing mechanisms for purification effects may lead to the direct emission of substandard air.

[0004] Therefore, there is an urgent need for a new type of ventilation and purification system for highway tunnels to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel ventilation and purification system for highway tunnels to solve the problems mentioned in the background section.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A novel ventilation and purification system for highway tunnels includes a floor slab and also includes: Side plate A is fixedly connected to the top wall of the base plate; Side plate B is fixedly connected to the top wall of the bottom plate, and both side plate B and the top wall of side plate A are fixedly connected to a top plate. A filter screen is fixedly connected between side plate A and side plate B. A baffle is fixedly connected between the top plate, the baffle, side plate A and side plate B. Mounting plates are fixedly connected to the top wall of the top plate and are symmetrically distributed about the mounting plates; The flow diversion and purification components include: A bottom positioning frame is fixedly connected to the bottom of the base plate, and a positioning groove is provided on the top of the bottom positioning frame; A gas purification plate is slidably connected to the inner wall of the positioning groove, and the outer wall of the gas purification plate is provided with uniformly distributed purification holes. A flow guide plate is fixedly connected to the side wall of the gas purification plate, and multiple sets of the flow guide plate are provided, with the spacing between the multiple sets of the flow guide plate decreasing sequentially. The reflux assembly, located on the side wall of side panel B, is used to reflux and purify substandard gases.

[0007] As a preferred technical solution of this application, the reflow component includes: The mounting bracket is fixedly connected to the side wall of side plate B, and a fan is fixedly connected to the outer wall of the mounting bracket; An air inlet pipe is fixedly connected to the air inlet of the fan, and the end of the air inlet pipe away from the air inlet of the fan is fixedly connected to the side plate B. An air outlet pipe is fixedly connected to the air outlet of the fan, and the end of the air outlet pipe away from the air outlet of the fan is fixedly connected to the side plate B.

[0008] As a preferred technical solution of this application, a drive motor is fixedly connected to the top wall of the top plate, and a valve plate is fixedly connected to the output end of the drive motor, and the valve plate is rotatably connected to the baffle.

[0009] As a preferred technical solution of this application, a gas sensor A is fixedly connected to the top wall of the base plate, and a gas sensor B is also fixedly connected to the top wall of the base plate, and both gas sensor A and gas sensor B are electrically connected to the drive motor. As a preferred technical solution of this application, a top positioning frame is fixedly connected to the outer wall of the top plate, and the top positioning frame is slidably connected to the gas purification plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By using multiple sets of guide vanes arranged with decreasing spacing, a labyrinthine air path is formed, which significantly extends the residence time of air in the purification zone, ensuring sufficient reaction between pollutants and purification materials, and improving purification efficiency. At the same time, the gas purification plate adopts a sliding connection method, which can be easily pulled out from the bottom positioning frame and the top positioning frame for replacement or regeneration. The maintenance operation is simple and does not require disassembly of the main structure, reducing maintenance costs and time. This solves the problem in the existing tunnel purification system where the purification process is short, resulting in insufficient contact between air and purification materials and thus incomplete purification. 2. By using the reflux assembly in conjunction with gas sensor A and gas sensor B, a real-time monitoring closed-loop feedback control is formed, ensuring that no air that has not been sufficiently purified is directly emitted. This guarantees the continuous stability and reliability of the outlet air quality, meets environmental standards, improves the reliability and adaptability of the system, and solves the problem in existing technologies that lack a real-time monitoring and reprocessing mechanism for purification effects, which may lead to the direct emission of substandard air.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0014] like Figure 1-5 As shown, this embodiment proposes a novel ventilation and purification system for highway tunnels, including a base plate 1, and further comprising: Side plate A2 is fixedly connected to the top wall of base plate 1; Side plate B3 is fixedly connected to the top wall of bottom plate 1, and top plate 4 is fixedly connected to both the top walls of side plate B3 and side plate A2. Filter screen 21 is fixedly connected between side plate A2 and side plate B3. Baffle 9 is fixedly connected between top plate 4, baffle 9, side plate A2 and side plate B3. Mounting plate 5 is fixedly connected to the top wall of top plate 4 and is symmetrically distributed about mounting plate 5; The flow diversion and purification components include: The bottom positioning frame 6 is fixedly connected to the bottom of the base plate 1, and the top of the bottom positioning frame 6 is provided with a positioning groove 7; The gas purification plate 14 is slidably connected to the inner wall of the positioning groove 7, and the outer wall of the gas purification plate 14 is provided with uniformly distributed purification holes 15. The guide plate 16 is fixedly connected to the side wall of the gas purification plate 14, and multiple sets of guide plates 16 are provided. The spacing between the multiple sets of guide plates 16 decreases sequentially. The air after preliminary purification enters the purification channel formed by the gas purification plate 14 and the guide plates 16. The multiple sets of guide plates 16 with decreasing spacing force the air flow path to be tortuous and extended, which greatly increases its residence time in the purification zone. When the air passes through the purification holes 15 on the gas purification plate 14, the gaseous pollutants in it are fully adsorbed or decomposed. The purpose of the sequentially decreasing spacing of the guide plates 16 is that the pollutant concentration is high at the inlet, requiring a larger space to ensure the flow capacity, and the concentration is low at the outlet, requiring a more tortuous path to ensure the final purification effect. The reflux assembly, located on the side wall of side panel B3, is used to reflux and purify substandard gases.

[0015] like Figure 4 As shown, in a preferred embodiment, based on the above method, the recirculation component further includes: Mounting bracket 17 is fixedly connected to the side wall of side plate B3, and fan 18 is fixedly connected to the outer wall of mounting bracket 17; The air intake pipe 19 is fixedly connected to the air inlet of the fan 18, and the end of the air intake pipe 19 away from the air inlet of the fan 18 is fixedly connected to the side plate B3. The exhaust pipe 20 is fixedly connected to the exhaust port of the fan 18, and the end of the exhaust pipe 20 away from the exhaust port of the fan 18 is fixedly connected to the side plate B3. The drive motor 10 controls the valve plate 11 to close or reduce the opening, and at the same time starts the return assembly. The fan 18 draws back the non-compliant gas through the intake pipe 19, and then sends it back to the system inlet through the exhaust pipe 20 for the next purification cycle until it meets the standard before it can be discharged.

[0016] like Figure 5 As shown, in a preferred embodiment, based on the above method, a drive motor 10 is fixedly connected to the top wall of the top plate 4, and a valve plate 11 is fixedly connected to the output end of the drive motor 10. The valve plate 11 is rotatably connected to the baffle 9. The drive motor 10 controls the valve plate 11 to open, thereby controlling the gas to be discharged and recirculated.

[0017] like Figure 4As shown, in a preferred embodiment, based on the above method, a gas sensor A12 is fixedly connected to the top wall of the base plate 1, and a gas sensor B13 is also fixedly connected to the top wall of the base plate 1. Both gas sensors A12 and B13 are electrically connected to the drive motor 10. The gas sensor A12, located at the inlet end, monitors the original air pollution concentration. The control system can integrate the data from the front and back end sensors, intelligently predict and adjust the system operating status, and achieve forward-looking control and energy-saving operation. The gas sensor B13, located at the outlet, monitors the quality of the gas in real time and feeds the data back to the control system.

[0018] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, a top positioning frame 8 is fixedly connected to the outer wall of the top plate 4, and the top positioning frame 8 is slidably connected to the gas purification plate 14. The top positioning frame 8 realizes the guiding and positioning function of the gas purification plate 14, which facilitates the quick installation and disassembly of the gas purification plate 14.

[0019] Specifically, in use, the ventilation and purification system of this novel highway tunnel works as follows: polluted air is propelled by external equipment to flow through the air. The air first passes through filter 21, where particulate impurities are removed, completing preliminary purification. The pre-purified air then enters a purification channel composed of gas purification plates 14 and guide plates 16. Multiple sets of guide plates 16 with progressively decreasing spacing force the airflow path to be tortuous and extended, greatly increasing its residence time in the purification zone. When the air passes through the purification holes 15 on the gas purification plates 14, the gaseous pollutants are fully adsorbed or decomposed. The air that has completed deep purification reaches the outlet end, where it is monitored by gas sensor B13. The system monitors air quality in real time and feeds the data back to the control system. When gas sensor B13 detects that the air quality meets the standards, drive motor 10 controls valve plate 11 to open, allowing clean air to be discharged directly. Drive motor 10 controls valve plate 11 to close or reduce its opening, and at the same time starts the recirculation component. Fan 18 draws back substandard gas through intake pipe 19 and then sends it back to the system inlet through outlet pipe 20 for the next purification cycle until the air quality meets the standards before it can be discharged. Gas sensor A12 installed at the inlet monitors the original air pollution concentration. The control system can integrate the data from front-end and back-end sensors to intelligently predict and adjust the system's operating status, achieving proactive control and energy-saving operation.
