Description:FIELD OF INVENTION

[001] The present invention relates to dust suppression equipment. Particularly, the present invention relates a dust suppression equipment that provides targeted size-based mist dispersion, thereby effective for removal of dust particle of wide range of size.

BACKGROUND OF THE INVENTION

[002] In rapidly industrializing and urbanizing cities, smoke and dust are created due to the exhaust fumes from vehicles, smoke from factories, and dust from construction sites. Among these, construction dust can be a significant problem for many people. Construction based airborne dust can cause a wide range of health and lung problems for construction workers, but it also creates a concern for people living near construction sites.

[003] In any construction project, there are three main types of dust that you might contend with, all of which cause serious health issues with continued exposure. Silica dust emerges when working with rocks, sandstone, brick and mortar, potentially damaging lung tissue if you inhale it. Wood dust is a concern when working with wood and contributes to the development of both cancer and asthma – making you four times more vulnerable to the latter. Hardwood dust in particular can cause a rare form of nose cancer. Finally, low-toxicity dust is present in low-silica materials, which can still cause long-term lung problems after frequent exposure.

[004] In response to these concerns, various measures have been implemented to limit or remove the dust from air in order to mitigate potential health risk associated with dust exposure from various sources. These measures include the use of traditional methods of dust suppression such as relying on water spraying or filtration systems. Water spraying can be inconvenient, lead to muddy conditions, and may not be effective for all pollutant types. Filtration systems require regular filter replacement, adding to operational costs and downtime.

[005] There are several patent applications that disclose a system and method to suppress dust from air. One such European patent application EP4015767A1 discloses a dust suppression system, particularly for underground work such as tunnels and the like, which comprises a trolley which is adapted to support a tank which is adapted to contain water, the tank being connected to a supply pump driven by a motor, the pump feeding a plurality of nozzles for atomizing the water, sensors being provided for the detection of environmental conditions for the activation of the nozzles. However, water spraying can be inconvenient, lead to muddy conditions, and is not be effective for all pollutant types.

[006] Other such patent application US20110232495A1 discloses a Dust suppression apparatus, comprising: (a) a turntable; (b) an engine; (c) a water mist blower comprising an air conduit, a plurality of water nozzles positioned so as to supply a spray of water to the air conduit, and a fan positioned so as to supply a stream of air through the air conduit, the water mist blower and the engine mounted on the turntable, the turntable adapted to permit the air conduit to be rotated horizontally, and the air conduit mounted so as to permit the air conduit to tilt vertically; (d) a water conduit adapted to supply pressurized water to the plurality of water nozzles; (e) a belt drive connected to the engine and adapted to supply power to the fan, and (f) a constant velocity joint connecting the belt drive to the fan. However, the cited invention is not capable of delivering mist of different size.

[007] In order to overcome the problem associated with the state of arts, there is a need for the development of an efficient apparatus for suppressing dust particles of different size in air that can overcome the aforesaid limitations in a more efficient manner.

[0011] Another objective of the present invention is to abate a wide range of dust particle sizes effectively due to targeted size-based mist dispersion.

[0012] Yet another objective of the present invention is to reduce water usage compared to traditional spraying methods.

[0013] Yet another objective of the present invention is to work effectively and withstand the harsh conditions of a construction site.

In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0027] The terms and words used in the following description and claims are not limited to the bibliographical meanings but are merely used to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the invention.

[0028] It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

[0029] It should be emphasized that the term “comprises/comprising” when used in this specification is taken to specify the presence of stated features, integers, steps, or components but does not preclude the presence or addition of one or more other features, integers, steps, components, or groups thereof.

[0030] Accordingly, the present invention relates to dust suppression apparatus. Particularly, the present invention relates to an apparatus that provides targeted size-based mist dispersion, thereby effective for removal of dust particle of wide range of size.

[0031] In an embodiment, as shown in Figure 1, an apparatus for suppressing dust particles of different size in air (100), comprise of an air suction unit (102), a mist generator (104) connected to the air suction unit (102), an ionization chamber (108) connected to the mist generator (104), a discharge unit (112) connected to the ionization chamber (108), and a control unit (118) connected to the mist generator (104), the ionization chamber (108), and the discharge unit (112).

[0032] The air suction unit (102) is configured to generate pressure difference between atmosphere and inside the apparatus (100) through a motor, wherein the generated pressure is negative so as to attract polluted air from atmosphere into the apparatus (100). The generated negative pressure creates a vacuum effect that pulls polluted air from atmosphere. The intake air is stripped off the particle contaminants and then the suctioned air is dispensed into the mist generator (106).

[0033] The mist generator (104) is configured to receive suctioned air from the air suction unit (102). Further, the mist generator (104) comprises of a water storage chamber (106). The water storage chamber (106) is adapted to store water. The mist generator (104) is configured to generate mist of variable size through interaction of air suctioned through the air suction unit (102), water stored in the water storage chamber (106), and an electromagnetic wave generator.

[0034] The electromagnetic wave generator utilizes electromagnetic radiation to break down the water molecules into mist particles of different size, wherein the size of formed mist particle may vary depending upon the targeted pollutant to be removed. The generated mist particles are then passed to the ionization chamber (108).

[0035] The ionization chamber (108) receives mist from the mist generator (104). The ionization chamber (108) comprises of a power source (110) to ionize the mist particles. Further, the power source (110) comprising a first electrode, and a second electrode, wherein the second electrode is adapted to shift position with respect to the first electrode to provide variable voltage. The variable voltage is produced by the power source (110) to account for different type of pollutant’s particle.

[0036] The ionization chamber (108) utilizes corona discharge technology to ionize mist particles. In the corona discharge technology, a current flows from an electrode with a high potential into a neutral fluid such as air, water, and the like, resulting in ionization of that fluid so as to create a region of high electric field around the electrode. The ions generated eventually pass the charge to nearby areas of lower potential. In the ionization chamber (108), charges are induced on the mist particles through electric field generated by the power source (110). Electric field flows from an electrode with a high potential into the mist particles, resulting in ionization of the mist particles. The ionized mist particles are then passed to the discharge unit (112).

[0037] In an exemplary embodiment, Figure 2 illustrates schematic diagram of the discharge unit (112) of the apparatus (100). The discharge unit (112) is configured to receive ionized mist particles from the ionization chamber (108). The discharge unit (112) further comprise of a mist discharge unit (114), and an air discharge unit (116). The mist discharge unit (114) release the ionized mist in a laminar flow into atmosphere through high pressure nozzles, wherein laminar flow is achieved by absorbing turbulence.

[0038] The ionized mist particles released in atmosphere, interact with dust particles that go on to further attract other dust particles & ultimately agglomerate other dust particles. Thus, dust pollutants are no longer suspended in the environment. The ionized mist particles also interact with VOCs & oxidizes them, further reducing pollution in the targeted environment.

[0039] Further, as shown in Figure 3 and Figure 4, the air discharge unit (116) placed in proximity to the mist discharge unit (114), comprises a plurality of channels such as horizontal channel (122) and a pair of vertical channels (124a-124b), to release air back into atmosphere in a laminar flow upon removing pollutants, wherein pollutants in air are removed through interaction of ionized mist particles and pollutants of suctioned air. The ionized mist particles interact with pollutants that induces charge on the pollutants. The charged pollutants further attract other pollutants, thereby resulting in agglomerating and settling of the pollutants.

[0040] The discharge unit (112) enables a laminar flow of clean air and mist particles through removing turbulence, at the junction of the apparatus (100) and environment. The ionized mist is passed through the plurality of channels (120, 122, 124a, 124b) that removes turbulent patches in the stream of mist particles and creates a well layered laminar flow. This creates a barrier of clean air & allows for the delivery of clean air over a long range.

[0041] Further, the discharge unit (112) utilizes Ultrasonic generator and nozzles, operated by converting high frequency sound waves into mechanical energy that is transferred into a water, breaking down the water molecule into smaller size. As the water molecules exits the atomizing surface of the nozzle, the liquid is broken into a fine mist of uniform micron sized droplets.

[0042] The control unit (118) is connected to the mist generator (104), the ionization chamber (108), and the discharge unit (112). The control unit (118) is configured to control the power source (110) of the ionization chamber (108), to generate variable voltage based on pollutant variable map wherein the pollutant variable map is generated based upon sampling and analysis of pollutants in the targeted environment. Further, the control unit (118) is configured to control the ionization chamber (108), the discharge unit (112) so as to manage flow and range of mist particles.

[0043] In an embodiment, the present invention also provides a method for suppressing dust particles of variable size in air, comprises the following steps:-
• suctioning of polluted air through the air suction unit (102);
• storing water in the water storage chamber (106);
• generating mist of variable size through the mist generator (104) by interaction of suctioned air, stored water, and the microwave generator;
• generation of variable electric field by the power source based on the pollutant variable map;
• ionizing the generated mist of variable size through the ionization chamber (108) by inducing charge on generated mist through electric field generated by the power source (110);
• discharging the ionized mist in laminar flow upon absorption of turbulence through the mist discharge unit (114);
• releasing clean air into atmosphere in laminar flow through the air discharge unit (116) upon cleaning air through interaction of the ionized mist particles and pollutants of suctioned air; and
• controlling flow, range and size of the discharged mist through the control unit (118);

[0044] In an embodiment the advantages of the present invention are enlisted herein:
• The present invention provides an apparatus that eliminates need for regular filter replacements, reducing maintenance costs and downtime.
