Description

Technical Field

[0001] This utility model relates to the field of PM2.5 particulate matter control technology, and in particular to a time-varying particle size low-altitude water curtain particulate matter removal device. Background Technology

[0002] PM2.5 (particulate matter with an aerodynamic diameter of ≤2.5 micrometers) is the primary pollutant endangering human health and environmental quality. It can penetrate deep into the lungs and even enter the bloodstream, triggering asthma, bronchitis, and cardiovascular diseases, and adsorbing toxic organic matter and heavy metals. Currently, existing technologies for PM2.5 control include source control technologies, end-of-pipe treatment technologies, open environment control technologies, indoor environment control technologies, and monitoring and precision management technologies. Among source control technologies, there are combustion process control technologies and dust suppression technologies. Dust suppression technology uses water mist to wet the surface of materials, inhibiting dust generation—a process known as wet dust suppression. In open environment control technologies, spray dust suppression systems are suitable for open spaces such as cities and construction sites. These systems include charged water mist technology and high-altitude spray systems. Charged water mist technology enhances the adsorption capacity of PM2.5 through charged water mist and requires a monitoring network for precise spraying. High-altitude spray systems involve installing spray facilities on the rooftops of high-rise buildings to create a regional water circulation mechanism. However, existing dust suppression technologies and spray dust reduction systems can only combine with (adsorb) suspended particulate matter, and cannot achieve rapid falling. In other words, suspended particulate matter and water mist are very likely to remain suspended in the air, and cannot reliably control suspended particulate matter.

[0003] Therefore, there is an urgent need to propose a time-varying particle size low-altitude water curtain particulate matter removal device that is simple in structure and reliable in treatment. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a time-varying particle size low-altitude water curtain particulate matter removal device. The technical solution adopted by this invention is as follows: A time-varying particle size low-altitude water curtain particulate matter removal device includes a drone, a variable particle size water curtain system suspended from the lower part of the drone, and a retractable pipe mechanism connected to the variable particle size water curtain system by a pipeline; the retractable pipe mechanism is externally connected to a water supply system. The variable particle size water curtain system includes an inner ring pipe and an outer ring pipe arranged in a central circle, an inlet pipe connected to a retracting and extending pipe mechanism, several first lower branch pipes connected between the inlet pipe and the inner ring pipe, a solenoid valve located at the upper part of the inlet pipe, a first upper branch pipe connected between the solenoid valve and the outer ring pipe, several hoisting connecting pipes evenly spaced between the inner ring pipe and the outer ring pipe, hoisting lugs located on the hoisting connecting pipes and connected to the UAV for hoisting, several first water curtain nozzles evenly spaced at the bottom of the inner ring pipe, and several second water curtain nozzles evenly spaced at the bottom of the outer ring pipe; the wet mist sprayed by the first water curtain nozzles has a particle size of 1-10 micrometers; the wet mist sprayed by the second water curtain nozzles has a particle size of 100-1000 micrometers; the first water curtain nozzles spray the first wet mist at an angle β towards the wind; the second water curtain nozzles spray the second wet mist at an interval T1; the spraying time of the second wet mist is T2; T1 and T2 are natural numbers greater than 0.

[0005] Furthermore, the windward angle β is 30°~60°.

[0006] Furthermore, the first lower bifurcation tube is provided with several negative charge emitting mechanisms; the negative charge emitting mechanism includes an end clamp and a side mounting bracket connected to the first lower bifurcation tube, and a negative charge generator disposed on the side mounting bracket.

[0007] Furthermore, the water inlet pipe is placed at the center of the inner ring pipe, and the first lower branch pipe and the first upper branch pipe are arranged in a ring at uniform intervals.

[0008] Furthermore, the pipe winding and unwinding mechanism includes a trailer, a pipe winding support frame and a battery fixed on the trailer, a bearing seat mounted on the pipe winding support frame, a reel rotatably mounted on the bearing seat (at least one reel is provided), a reel motor assembly mounted on the pipe winding support frame and driving the reel to rotate, a water pipe wound on the reel, and a rotary joint that passes through the bearing seat and is connected to one end of the water pipe; the other end of the water pipe is connected to a variable particle size water curtain system; and the rotary joint is externally connected to a water supply system.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This invention involves spraying a first wet mist and a second wet mist at an angle β upstream of the area where suspended particulate matter is to be degraded. The first wet mist (charged) adsorbs the suspended particulate matter, and the water droplets formed by the second wet mist, under the action of inertial collision, cause the first wet mist, suspended particulate matter, and second wet mist (water droplets) to fall rapidly, thereby achieving reliable treatment of PM2.5 suspended particulate matter.

[0010] This utility model employs an inner ring pipe, an outer ring pipe, a first water curtain nozzle, and a second water curtain nozzle. The first water curtain nozzle is located at the bottom of the inner ring pipe and sprays a wet mist of 1-10 micrometers. The second water curtain nozzle is located at the bottom of the outer ring pipe and sprays a wet mist of 100-1000 micrometers. The second wet mist envelops the first wet mist, ensuring that the first wet mist is reliably impacted and falls.

[0011] This invention ensures flexibility and reliability by setting up a tube delivery and take-up mechanism and coordinating with the movement of the drone.

[0012] (4) The first lower branch pipe, the first upper branch pipe, the inner ring pipe, the outer ring pipe, the hoisting connecting pipe and the hoisting lug of this utility model are evenly arranged to ensure that they are balanced under force.

[0013] In summary, this utility model has the advantages of simple logic and reliable treatment, and has high practical and promotional value in the field of PM2.5 particulate matter control technology. Attached Figure Description
