[0002] In recent years, with the acceleration of urbanization in my country, dust pollution has become increasingly serious, posing a great threat to people's health and lives and directly affecting the health of urban residents. It has become a focus of public attention. Existing road dust control measures typically use water trucks and mist cannons. Traditional water trucks and mist cannons are semi-mechanical and semi-manual dust suppression measures. During the dust suppression process, they are mobile and regional spraying, which cannot be fixed in a certain area for long-term continuous spraying. The range and area of ​​dust suppression are limited, and it is impossible to suppress dust in a large area at the same time. The overall effect of dust control is poor. At the same time, because the sprayed water mist particles are too large, water resources are wasted, and the operating cost is relatively high. The large water particles can also cause some inconvenience to pedestrians on the roadside. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a road dust suppression spraying device that addresses the above-mentioned shortcomings of the prior art, effectively improves the dust suppression effect, solves the problem of small operating area and large water droplets of fog cannon trucks, and has the characteristics of wide applicability and strong practicality.

[0004] The technical solution adopted by this utility model is: a road dust suppression spraying device, including a double-arm lamp post, with symmetrically arranged mounting rods on both sides of the upper end of the double-arm lamp post, a water delivery pipe on one side of the double-arm lamp post, a spray pipe connected to the upper end of the water delivery pipe on the mounting rod, a plurality of multi-head low-pressure atomizing nozzles with different spray angles on the spray pipe, a water supply main pipe connected to the lower end of the water delivery pipe, a water supply pump station connected to the water supply main pipe, a control component for controlling the opening and closing of the pipeline between the water delivery pipe and the water supply main pipe, and an environmental monitoring station electrically connected to the control component.

The inlet of the resin tank is connected to the water supply pump station, the outlet of the resin tank is connected to the main water supply pipe, and the outlet of the salt tank is connected to the backwash port of the resin tank through a pipe.

[0006] As a further improvement, the control components include an environmental control solenoid valve and a ball valve, which are installed on the water delivery pipe, and the environmental control solenoid valve is electrically connected to the environmental monitoring station.

[0007] Furthermore, the bottom of the water supply pipe is connected to a branch pipe, and a bypass pipe and a water supply pipe are provided between the branch pipe and the main water supply pipe. The control component is installed on the water supply pipe.

[0008] Furthermore, a bypass valve is provided on the bypass pipeline, and a shut-off valve is provided at both ends of the water distribution pipe.

[0009] Furthermore, the water delivery pipe is installed on the double-arm lamp post using multiple stainless steel pipe clamps.

[0010] Furthermore, a protective pipe is fitted around the outside of the water delivery pipe.

[0011] Furthermore, the protective pipe is made of PVC material, and the water delivery pipe is made of PE material.

[0014] Beneficial effects

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This utility model discloses a road dust suppression spraying device. By adding spraying devices to double-arm lampposts, water is supplied from a pumping station to the main water supply pipe, which then circulates to every part of the road. Environmental monitoring stations are deployed throughout the city to automatically sense the dust concentration in the air. When the environmental monitoring station detects that the dust concentration exceeds a set value, it transmits a signal to the controller. The controller then opens the environmental control solenoid valve, connecting the water delivery pipe to the main water supply pipe. The spray water enters the spray pipe through the delivery pipe and is atomized by multiple multi-head low-pressure atomizing nozzles, forming a micron-sized water mist with similar dust particle sizes for more targeted dust suppression. The dust suppression spray system captures suspended particles in the air, causing them to agglomerate and settle under gravity, thus achieving a dust suppression effect and significantly improving dust reduction. The dust suppression spray device can adsorb impurities in the air, creating a clean and fresh environment, achieving multiple functions such as dust reduction, cooling, and humidification. Utilizing the characteristics of streetlight poles—wide distribution, high density, and fixed location—the system fully leverages environmental monitoring station data to systematically carry out road dust suppression, solving the problems of small operating area and large water droplets encountered by fog cannon trucks. By installing a safety filtration device, calcium and magnesium ions in the water are removed, reducing scale formation, protecting the equipment, and extending its service life.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0021] See Figure 1-2As shown, this utility model discloses a road dust suppression spraying device, including a double-arm lamp post 1. The upper ends of the double-arm lamp post 1 are symmetrically arranged mounting rods 19 on both sides. A water delivery pipe 4 is provided on one side of the double-arm lamp post 1. A spray pipe 5, connected to the upper end of the water delivery pipe 4, is provided on the mounting rod 19. The spray pipe 5 is equipped with multiple multi-head low-pressure atomizing nozzles 6 with different spray angles. The lower end of the water delivery pipe 4 is connected to a main water supply pipe 12, which is connected to a water supply pump station 7. A control device is provided between the water delivery pipe 4 and the main water supply pipe 12. The control component 2 for opening and closing the pipeline is electrically connected to the environmental monitoring station 8. A spray device is installed on the double-arm lamppost 1. During use, water is supplied to the main water supply pipe 12 via the water supply pump station 7, and then circulated to every part of the road. The environmental monitoring station 8 is deployed in various corners of the city, automatically sensing the dust content in the air. When the environmental monitoring station 8 detects that the dust concentration in the air exceeds a set value, it transmits a signal to the controller. The controller then controls the environmental control solenoid valve 21 to open, at which point the pipeline... Water pipe 4 is connected to the main water supply pipe 12. Spray water enters the spray pipe 5 through the water supply pipe 4 and is atomized by multiple multi-head low-pressure atomizing nozzles 6 to form micron-sized water mist with similar dust particle sizes. This allows for more targeted capture of suspended particles in the air, causing them to agglomerate and settle under gravity, thus achieving dust suppression. The dust suppression spray device can adsorb impurities in the air, creating a clean and fresh environment, achieving multiple functions such as dust suppression, cooling, and humidification. Utilizing the characteristics of streetlight poles—wide distribution, high density, and fixed location—the streetlight pole spray system fully leverages environmental monitoring station data to systematically carry out road dust suppression. This solves the problem of small operating area and large water droplets from fog cannon trucks. At the same time, the micron-sized particles sprayed by the spray device easily evaporate, absorbing heat from the surrounding environment during evaporation, thus effectively controlling the temperature of the local area. In summer, it plays a role in temperature regulation and heatstroke prevention. In hot summer weather, pedestrians walking on the roadside can feel a slight coolness, thus achieving a heatstroke prevention and cooling function.

[0022] Specifically, the security filtration device 3 includes a resin tank 31 and a salt tank 32. The inlet of the resin tank 31 is connected to the water supply pump station 7, and the outlet of the resin tank 31 is connected to the main water supply pipe 12. The outlet of the salt tank 32 is connected to the backwash port of the resin tank 31 through a pipe. The municipal water is softened through the resin tank 31 to ensure water quality. At the same time, it removes calcium and magnesium ions from the water, reduces the formation of scale, protects the equipment and extends its service life, and prevents the pipes and low-pressure atomizing nozzles 6 from clogging. The salt tank 32 contains a high concentration of brine. The high concentration of brine is used to flow through the resin to restore the exhausted resin to sodium form resin.

[0023] Preferably, the control component 2 includes an environmental control solenoid valve 21 and a ball valve 22. The environmental control solenoid valve 21 and the ball valve 22 are installed on the water delivery pipe 4. The environmental control solenoid valve 21 is electrically connected to the environmental monitoring station 8. The environmental control solenoid valve 21 controls the on / off switch of the spray device, which can realize real-time spray control and automatic spray control when dust exceeds the standard, thereby effectively controlling the PM2.5 / PM10 and other indicators of the project section to meet the environmental monitoring standards.

[0024] Furthermore, the bottom of the water supply pipe 4 is connected to a branch pipe 9. A bypass pipe 10 and a water supply pipe 11 are provided between the branch pipe 9 and the main water supply pipe 12. The control component 2 is installed on the water supply pipe 11.

[0025] Furthermore, a bypass valve 13 is provided on the bypass pipe 10, and a shut-off valve 14 is provided at both ends of the water distribution pipe 9. The shut-off valve 14 is used to flexibly control both ends of the water distribution pipe 9. When needed, it can be opened to connect to an external water source to improve usability.

[0026] Furthermore, the water delivery pipe 4 is installed on the double-arm lamp post 1 by multiple stainless steel pipe clamps 15, which facilitates the installation and fixation of the water delivery pipe 4.

[0027] Furthermore, a protective pipe 16 is fitted around the outside of the water delivery pipe 4 to protect the water delivery pipe 4.

[0028] Furthermore, the protective pipe 16 is made of PVC material, and the water conveying pipe 4 is made of PE material. PVC pipe has good acid resistance, alkali resistance and corrosion resistance, and can protect the water conveying pipe 4 well.

[0029] Furthermore, the top of the double-arm lamp post 1 is equipped with a lightning protection conductor 17, which serves to protect against lightning strikes and prevent damage to the equipment.

[0030] Furthermore, the multi-head low-pressure atomizing nozzle 6 is installed on the water spray pipe 5 through the tee connector 18. The distance between two adjacent multi-head low-pressure atomizing nozzles 6 is 50-80mm. The reasonable distance arrangement allows the atomized water sprayed by the multi-head low-pressure atomizing nozzle 6 to more effectively reduce dust from all directions and improve the dust reduction effect.

[0031] In this embodiment, a road dust suppression spraying device supplies water to the main water supply pipe 12 via a water supply pump station 7. The water then flows to every part of the road. Environmental monitoring stations 8 are deployed throughout the city, automatically sensing the dust concentration in the air. When the environmental monitoring station 8 detects that the dust concentration exceeds a set value, it transmits a signal to the controller. The controller then controls the environmental control solenoid valve 21 to open. At this time, the water delivery pipe 4 connects to the main water supply pipe 12, and the spray water enters the spray pipe 5 through the water delivery pipe 4. It is then atomized by multiple multi-head low-pressure atomizing nozzles 6, forming micron-sized water mist with similar dust particle sizes. This allows for more targeted capture of suspended particles in the air, causing them to agglomerate and settle under gravity, thus achieving a dust suppression effect. The dust reduction effect is significantly improved, while also saving water and reducing water costs. This road dust suppression spraying device effectively improves the dust suppression effect, solves the problems of small operating area and large spray droplets of fog cannon trucks, and has the characteristics of wide applicability and strong practicality.
