[0022] like Figures 1 to 3As shown, the highway engineering construction dust reduction device of this embodiment includes a water storage tank 1, and a filter screen 14 is arranged inside the water storage tank 1. The filter screen 14 is used to filter water molecules. The water molecules will fall to the bottom of the water storage tank 1 through the filter screen 14 and be stored. A communicating ventilation pipe 3 is installed at the upper end of the water storage tank 1. The ventilation pipe 3 is a wider vertical pipe for the circulation of air. A supporting bottom plate 12 is installed on the inner wall surface of the ventilation pipe 3 through a plurality of connecting rods 13. One end of the plurality of connecting rods 13 is connected to the inner wall of the ventilation pipe 3, and the other end is jointly installed with the supporting bottom plate 12. The shape of the supporting bottom plate 12 is a trapezoid with a narrow upper part and a wide lower part. The supporting bottom plate 12 is a trapezoid with a narrow upper part and a wide lower part, and the side is an inclined surface. When water mist falls on the upper end of the supporting base, it will slide down along the inclined surface of the supporting base under the action of gravity to avoid water stains remaining on the upper end of the supporting base. A fan 11 is installed at the lower end of the supporting bottom plate 12, and the fan 11 is connected to the outside The power supply of the part will generate an airflow from top to bottom when it is turned on, and the external airflow can be sucked into the interior of the ventilation duct 3. A plurality of spray nozzles 9 are installed in an array at a position above the fan 11 and located on the inner wall surface of the ventilation duct 3. The spray nozzles 9 can spray water mist to absorb dust in the airflow. An annular plate 6 communicating with the plurality of spray nozzles 9 is installed on the outer surface of the ventilation duct. A second water pipe 5 communicating with the water storage tank 1 is installed at the lower end of the annular plate 6. An internal water pump is installed at the connection between the second water pipe 5 and the water storage tank 1. The plurality of spray nozzles 9 will spray water mist outward, and the water mist drives the dust to fall into the interior of the water storage tank 1. Under the action of the filter 14, water molecules enter the water storage tank 1 for storage, and the dust is isolated above the filter 14. The water inside the water storage tank 1 is pumped into the second water pipe 5 through the internal water pump, and is sent to the annular plate 6 through the second water pipe 5, and finally enters the plurality of spray nozzles 9 for reuse, thereby reducing the waste of water resources.

[0023] Specifically, a plurality of water grooves 10 are arranged in an array on the inner wall surface of the ventilation duct 3. Under the action of the fan 11, part of the sprayed water mist will be blown to the side wall surface of the ventilation duct 3. The surface of the water grooves 10 is relatively smooth, which can accelerate the speed at which the water stains slide downward.

[0024] Furthermore, two dust outlet holes 2 are symmetrically opened above the filter 14 on the side surface of the water tank 1. The airflow entering the ventilation pipe 3 will be discharged from the two dust outlet holes 2. Under the action of the airflow, the dust on the surface of the filter 14 will also be synchronously brought out.

[0025] Furthermore, a first water pipe 4 is installed at the lower end of the annular plate 6, and the first water pipe 4 is connected to an external water pump and a water source. A control system 8 is installed inside the water tank 1, and the control system 8 is electrically connected to the internal water pump connected to the second water pipe 5 and the external water pump connected to the first water pipe 4. The operation of the internal water pump and the external water pump can be controlled by the control system 8. When the water source inside the water tank 1 is less, the control system 8 will turn on the external water pump to drive the water source from the first water pipe 4 into the inside of the annular plate 6. When the water source inside the water tank 1 is more, the internal water pump will be turned on to drive the water source from the second water pipe 5 into the inside of the annular plate 6.

[0026] Furthermore, the control system 8 includes a first water level sensor 801 and a second water level sensor 802. The first water level sensor 801 is located at a lower part of the inner wall of the water tank 1, and the second water level sensor 802 is located at a higher part of the inner wall of the water tank 1. The first water level sensor 801 is electrically connected to an external water pump connected to the first water pipe 4, and the second water level sensor 802 is electrically connected to an internal water pump connected to the second water pipe 5. The first water level sensor 801 and the second water level sensor 802 are respectively located at the bottom and a higher part of the water tank 1. When the water level meets the second water level sensor 802, the internal water pump connected to the second water pipe 5 will start. When the water level cannot meet the first water level sensor 801, the external water pump will start until the water level meets the second water level sensor 802 at a higher part. At this time, the external water pump will be turned off and the internal water pump will be turned on.

[0027] Furthermore, an air inlet 7 with a larger opening is installed at the upper end of the ventilation pipe 3 , and the air inlet 7 with a larger opening can facilitate more airflow to enter the interior of the ventilation pipe 3 .

[0028] The method of using this embodiment is as follows: by installing a fan 11 inside the ventilation pipe 3, the fan 11 is connected to an external power supply, and when it is turned on, an airflow from top to bottom is generated. The airflow will drive nearby dust into the interior of the ventilation pipe 3 and flow downward, and multiple spray ports 9 will spray water mist outward, and the water mist drives the dust to fall into the interior of the water tank 1. Under the action of the filter 14, water molecules enter the water tank 1 for storage, and the dust is isolated above the filter 14. The water inside the water tank 1 is pumped into the second water pipe 5 through the internal water pump, and is sent to the annular plate 6 through the second water pipe 5, and finally enters the multiple spray ports 9 for reuse. When the water source inside the water tank 1 is insufficient, the external water pump can be turned on through the control system 8 to send the external water source from the first water pipe 4 into the annular plate 6 to meet the needs of multiple spray ports 9.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
