Description

Technical Field

[0001] This utility model belongs to the field of environmental pollution control technology, specifically relating to a water mist dust suppression device. Background Technology

[0002] With the acceleration of industrialization, the negative impacts of dust pollution from various industrial production activities on human health, production activities, the environment, and climate cannot be ignored. To reduce and eliminate the adverse effects of dust, various dust removal technologies are widely used in various dust pollution control scenarios. Among them, water mist dust removal technology reduces the concentration of dust in the air by causing water mist particles to collide, adhere, and condense with airborne dust particles, forming larger dust agglomerates that settle to the ground. In traditional water mist dust removal processes, the water mist particles sprayed from the nozzles have a short residence time in the air due to gravity, resulting in low dust removal efficiency. A large amount of water is required to achieve a good dust removal effect. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] like Figure 1 and Figure 2 As shown, this utility model provides a water mist dust suppression device. The portal frame 100 includes a top horizontal beam, side columns 110, and a bottom plate. Universal casters 120 are fixed below the bottom plate to allow for flexible movement or horizontal rotation of the water mist dust suppression device. Figure 1 , Figure 3 and Figure 4As shown, the column 110 includes a hollow telescopic rod 111, which allows the side column 110 of the portal frame 100 to be telescopically adjustable to facilitate adjustment of the dust removal height of the device. An insulating shell 200 is disposed on the top of the portal frame 100, with the opening of the insulating shell 200 facing downwards. The spray nozzle 300 and the charged electrode 500 are located inside the cavity of the insulating shell 200, which serves as a shield for protection. Several spray nozzles 300 are connected to a water supply pipe 400. The water supply pipe 400 is a retractable flexible hose, fixed inside the upright of the portal frame 100 and connected to a water tank 920 located at the bottom of the portal frame 100. The water tank 920 is connected to the water supply pipe 400 via a booster pump 910. The charged electrode 500 is connected to the portal frame 100 and located below the spray nozzles 300. Optionally, the charged electrode 500 is a plurality of annular electrodes, each corresponding to a spray nozzle 300, with the spray path of the spray nozzle 300 passing through the corresponding annular electrode; or, the charged electrode 500 includes a parallel cylindrical electrode group, with the spray path of the spray nozzle 300 passing through the plane of the parallel cylindrical electrode group. The charged electrode 500 makes the water mist sprayed from the spray nozzle 300 an electrically charged water mist.

[0046] In Example 1, as Figure 1 and Figure 2 As shown, the magnetic field generator 600 is disposed on the side of the portal frame 100 and below the insulating housing 200. Exemplarily, the magnetic field generator 600 includes several pairs of electromagnets 610, which are disposed opposite to each other on the side of the portal frame 100; the magnetic fields generated by adjacent pairs of electromagnets 610 are in opposite directions. Alternatively, the magnetic field generator 600 includes several sets of Helmholtz coils, which are disposed on the side of the portal frame 100; the magnetic fields generated by adjacent sets of Helmholtz coils are in opposite directions. In addition to gravity and air resistance, the charged water mist is deflected by the Lorentz force of the magnetic field. The opposing magnetic forces of the multiple sets of magnetic field generators 600 cause the water mist particles to follow an S-shaped trajectory, altering their original falling trajectory and prolonging their airborne time. This increases the probability of collision, adsorption, and condensation with airborne dust particles, improving dust removal efficiency and saving water consumption.

[0047] In Example 2, as Figure 3As shown, the electric field generator 700 is disposed on the side of the portal frame 100 and below the insulating housing 200. Exemplarily, the electric field generator 700 includes several pairs of electrode plates 710, which are disposed opposite to each other on the side of the portal frame 100. The electric fields generated by adjacent pairs of electrode plates (710) have opposite directions. In this embodiment, the charged water mist is deflected by the electric field force. The electric field forces of multiple sets of electric field generators 700 are in opposite directions, which also makes the water mist particles move in an S-shaped path, changing their original falling trajectory, prolonging the water mist particles' time in the air, and increasing the probability of them colliding, adsorbing, and condensing with dust particles in the air, thus improving dust removal efficiency and saving water usage.

[0048] In embodiment 3, the magnetic field generator 600 and the electric field generator 700 are arranged sequentially from top to bottom on the side of the portal frame 100 and located below the insulating shell 200; the magnetic field force generated by the magnetic field generator 600 on the charged water mist and the electric field force generated by the electric field generator 700 on the charged water mist are in opposite directions.

[0049] In the above embodiments, the charged electrode 500, the magnetic field generator 600 and / or the electric field generator 700, the booster pump 910 are connected to the controller 800.

[0050] As in Examples 1-3, the water mist dust suppression device provided by this utility model applies an external magnetic field or electric field to the area below the sprayed charged water mist. This causes the charged water mist to be deflected by the Lorentz force of the magnetic field or the Coulomb force of the electric field, in addition to gravity and air resistance. This alters the original falling trajectory, prolongs the time the water mist particles remain in the air, and increases the probability of them colliding, adsorbing, and condensing with dust particles in the air, thereby improving dust removal efficiency and saving water consumption. The pressure, particle size, charge type, charge intensity, magnetic field strength, and electric field strength of the water mist can all be adjusted by corresponding devices such as the booster pump 910, the nozzle diameter of the spray nozzle 300, the electric field generator 700, and the magnetic field generator 800, allowing for the selection of appropriate parameters according to dust removal needs. Furthermore, the height of the portal frame 100 can also be freely adjusted by the hollow telescopic rod 111, making this device applicable to dust pollution control in different scenarios and with a wide range of applications.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
