Description

Technical Field

[0001] This utility model belongs to the field of emergency kit technology, specifically relating to an integrated monitoring emergency kit suitable for handling hazardous chemicals in road (bridge) surface runoff. Background Technology

[0002] Currently, with the advancement of science and technology, the improvement of industrial production capacity, and the inevitable guidance of market demand, the production fields of chemical products, new materials, and synthetic biology are experiencing explosive growth. These products are diverse, mainly including petroleum, pesticides, pharmaceuticals, dyes, coatings, reagents, and many other categories.

[0003] With the increasing demand for chemical products, the number of vehicles transporting hazardous chemicals on highways is also increasing. In the event of a leak, it can cause significant pollution to the local environment and ecosystem. During the construction of highway infrastructure in my country, some highways inevitably cross rivers and lakes, and some of these water bodies have high water quality requirements. To ensure the safety of these water bodies and prevent potential hazardous chemical leaks during transport, environmental protection departments require that bridge runoff from highways crossing sensitive water bodies not be directly discharged into rivers. Bridge runoff collection is a mandatory environmental protection facility required by national environmental laws and regulations. Bridge runoff collection devices have become an important environmental protection project in transportation environmental protection and serve as a crucial basis for the environmental impact assessment approval and environmental protection acceptance of highway projects.

[0004] In recent years, the state has strengthened safety risk management and control in chemical industrial parks and industrial zones. Through a series of safety risk investigations and remediation efforts, it has strived to improve the inherent safety level of these parks, enhance their emergency response capabilities, and prevent major and serious safety accidents involving hazardous chemicals. These parks should construct public emergency wastewater pools to ensure they meet emergency response requirements in the event of a chemical safety accident. There is an urgent need for an integrated intelligent monitoring and emergency response kit for hazardous chemicals that combines emergency response, sedimentation, and emergency drainage to meet the needs of such applications. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an intelligent monitoring and emergency kit for hazardous chemicals. This kit is highly integrated and can be used to treat both hazardous chemical runoff and ordinary rainwater runoff. It also features "zero water balance and instant emptying."

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent monitoring and emergency box for hazardous chemicals, comprising a box body, a water inlet pipe for introducing fluid, and an exhaust port located at the top of the box body. The box body is divided into an emergency chamber and a clean water chamber by a partition. A valve box is located in the emergency chamber. The water inlet pipe is located on one side of the clean water chamber. The clean water chamber is separated by an overflow plate to form a sedimentation tank. A sludge guide plate is located below the overflow plate. The sludge guide plate includes an inclined portion and a vertical portion. The vertical portion, the side wall of the box body, and the bottom wall of the box body form a groove. A negative pressure sludge discharge pipe is located within the groove, with one end of the negative pressure sludge discharge pipe extending out from the partition. The plate enters the valve box and connects to the mud pump fixed inside the valve box. The other end of the negative pressure mud discharge pipe is closed, and the wall of the negative pressure mud discharge pipe is provided with a mud discharge hole. The inclined part of the mud guide plate forms a drainage chamber with the bottom wall of the box. The overflow plate has a second gap with the left side wall of the box, the overflow plate has a first gap with the top wall of the box, and the top of the partition plate has a third gap with the top wall of the box. The sedimentation tank is equipped with a sedimentation unit. It also includes a detector for detecting hazardous chemicals. When the detector detects a hazardous chemical leak, all valves used to control the mud pump and the water pump will automatically close. The entire box is an emergency collection device.

[0007] Preferably, the overflow plate is provided in multiple ways, dividing the water purification chamber into two or more sedimentation tanks, and there is only one second gap.

[0008] Preferably, each sedimentation tank is equipped with a sedimentation unit, and the sedimentation unit includes an anti-disturbance device and a rapid sedimentation device fixedly connected to the overflow plate, with the rapid sedimentation device located above the anti-disturbance device.

[0010] Preferably, the rapid settling device includes a plurality of settling plates that are inclined relative to the horizontal plane, and the two adjacent settling plates are arranged in parallel.

[0011] Preferably, the inlet pipe is located at the first sedimentation tank on the right side, and a baffle plate is provided between the partition and the overflow plate near the outlet of the inlet pipe. A downwardly inclined stress-relief plate is fixedly connected to the baffle plate, and a water guide plate is provided at the lower end of the stress-relief plate and fixed to the rear wall of the tank.

[0012] Preferably, a filter box is provided between the water inlet pipe and the housing, and the filter box is detachably located in the filter box.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Please see Figures 1-3 This utility model provides the following technical solution: an intelligent monitoring emergency box for hazardous chemicals, including a box body 1, a water inlet pipe 2 for introducing fluid, and an exhaust port 29 located at the upper end of the box body 1. The box body 1 is divided into an emergency chamber 4 and a clean water chamber 5 by a partition 3. A valve box 6 is located in the emergency chamber 4. The water inlet pipe 2 is located on one side of the clean water chamber 5. The clean water chamber 5 is divided into a sedimentation tank 7 by an overflow plate 8. A sludge guide plate 9 is located at the lower part of the overflow plate 8. The sludge guide plate 9 includes an inclined portion 10 and a vertical portion 11. The vertical portion 11, the side wall of the box body, and the bottom wall of the box body form a groove 12. A negative pressure sludge discharge pipe 13 is located in the groove 12. One end of the negative pressure sludge discharge pipe 13 extends out of the partition 3 and enters the valve box. The door box 6 is connected to the mud pump 28 fixed inside the valve box 6. The other end of the negative pressure mud discharge pipe 13 is sealed by the box wall, and the wall of the negative pressure mud discharge pipe 13 is provided with a mud discharge hole 14. The inclined part 10 of the mud guide plate 9 forms a drainage chamber 15 with the bottom wall of the box. The overflow plate 8 has a second gap 16 with the left side wall of the box 1, the overflow plate 8 has a first gap 17 with the top wall of the box 1, and the top of the partition plate 3 has a third gap 18 with the top wall of the box 1. The sedimentation tank 7 is provided with a sedimentation unit and also includes a detector 26 for detecting hazardous chemicals. When the detector 26 detects a hazardous chemical leak, all valves used to control the mud pump and the water pump are automatically closed. The entire box is an emergency collection device. Preferably, the emergency box is composed of one main box and multiple auxiliary boxes in any combination, and the main box and auxiliary boxes are connected by pipes.

[0029] Initially, the mud pump 28 and drainage chamber 15 are closed. Bridge surface runoff enters the tank 1 through the inlet pipe 2, first flowing into the settling tank 7. After settling in the settling tank 7, the runoff, having settled in a sedimentation unit, overflows through the overflow plate 8 (leaving a first gap 17 between the overflow plate 8 and the top wall of the tank 1) into the drainage chamber 15. The drainage chamber 15 then discharges the treated water. Through inclined plate sedimentation technology, the bridge surface runoff is discharged after sedimentation, thus better protecting the surrounding water environment. The mud pump 28 is then activated to extract the settled mud. It should be noted that the pump's operation is controlled by an external control box. Based on the tank volume and the actual storage capacity of the project, the system automatically activates the mud pump 28 during rainfall or after a period of rainfall, such as approximately 30 minutes or 1 hour. Alternatively, a sensor for detecting sludge position can be used to control the pump's operation. If a sensor is used, it is located in the last settling tank, the one furthest from the inlet. It is evident that, for drainage, it is possible to collect, settle, treat, and discharge simultaneously, adopting the principles of "zero water balance" and "discharge and empty immediately" to achieve normal road and bridge surface runoff discharge.

[0030] When handling hazardous chemicals, the mud pump 28 and drainage chamber 15 are shut off. Settling occurs through the aforementioned process, with the settling tank 7 acting as a water storage tank. Before rescue units arrive, excess hazardous chemicals pass through the settling tank 7 and the second gap 16 at the top of the overflow plate 8, eventually entering the drainage chamber 15, which also functions as a water storage tank. Furthermore, if rescue units still haven't arrived, the liquid level in the settling tank 7 will continue to rise. Once it reaches the top of the baffle 3, it enters the emergency chamber 4 through the third gap 18 between the top of the baffle 3 and the top wall of the tank 1. Therefore, the settling tank 7, drainage chamber 15, emergency chamber 4, overflow plate 8, and baffle 3, through their coordinated functions, enable this invention to prevent hazardous chemical leaks. Through monitoring and control devices, in the event of a hazardous chemical leak, the entire tank 1 serves as a collection tool, trading space for time.

[0031] Preferably, the sedimentation unit includes an anti-disturbance device 19 and a rapid settling device 20 fixedly connected to the overflow plate 8. The rapid settling device 20 is located above the anti-disturbance device 19. Specifically, the anti-disturbance device 19 consists of multiple mudguards with a water passage gap between adjacent mudguards. The rapid settling device 20 includes multiple settling plates 30 inclined relative to the horizontal plane, with two adjacent settling plates 30 arranged parallel to each other. To reduce the disturbance of the water flow to the sediment already settled at the bottom of the tank, this invention uses multiple elongated mudguards. The cross-section of a single mudguard is similar to a polygonal "Λ" shape, forming a "large inlet and small outlet" shape when viewed from above. This arrangement facilitates rapid sediment settling, reduces the disturbance of the water flow to the bottom silt, and even if large particles of sediment are agitated after settling, they will be blocked by the mudguards, thus not significantly affecting the settling effect. Furthermore, the inlet pipe 2 is located at the first settling tank 7 on the right side. A baffle plate 21 is installed between the partition plate 3 and the overflow plate 8 near the outlet of the inlet pipe 2. A downwardly inclined stress-relief plate 22 is fixedly connected to the baffle plate 21. A guide plate 23 is fixed to the rear wall of the tank body 1 at the lower end of the stress-relief plate 22. This arrangement, through the stress-relief effect of the stress-relief plate 22 and the guide plate 23, greatly alters the flow direction of the liquid and prevents the liquid from the outlet of the inlet pipe 2 from directly entering the bottom of the settling tank 7, thus avoiding affecting the settling effect.

[0032] Based on the above solution, in order to purify the bridge surface runoff and reduce environmentally unfriendly substances such as tire abrasion particles, and obtain more vegetation-friendly drainage, the inventors have installed multiple overflow plates 8. Specifically, multiple overflow plates 8 are provided, dividing the clean water chamber 5 into two or more sedimentation tanks 7, and there is only one second gap 16. Through this arrangement, the bridge surface runoff can pass through multiple sedimentation stages from right to left into the drainage chamber 15, resulting in more environmentally friendly drainage.

[0033] Preferably, a filter box 24 is provided between the water inlet pipe 2 and the housing 1, and the filter box 24 is detachably located in the filter box 25; a detector 26 for detecting hazardous chemicals is provided at the water inlet pipe 2; a drain pipe 27 is provided at the drainage chamber 15, and one end of the drain pipe 27 extends out of the partition 3 and is connected to the water pump fixedly connected to the valve box 6. This is prior art and will not be described in detail here. It should be noted that the detector 26 can be located on the housing 1 or on other pipe walls.

[0034] Preferably, the density of the sludge discharge holes 14 on the negative pressure sludge discharge pipe 13 decreases sequentially from right to left. This invention employs three or more stages of sedimentation technology. The structural design of this invention is as follows:

[0035] The amount and size of sediment deposited in the three settling tanks 7 are inconsistent. The first-stage settling tank 7 has large sediment particles and a large amount of sediment, which gradually decreases in the second and third stages. Therefore, the overflow plate 8 of this invention is provided in multiple locations, dividing the water purification chamber 5 into two or more settling tanks 7. Only one of the second gaps 16 is designed with a negative pressure sludge discharge pipe 13. The first settling tank 7 is located at the front end of the sludge discharge port, and the number of sludge discharge holes in the area of ​​the first settling tank 7 is designed to be larger, with the density decreasing from right to left. This design facilitates the limited discharge of the larger amount of sediment and large pieces of sediment in the first settling tank 7.

[0036] In conclusion, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
