The present invention generally relates to a filtration apparatus and more particularly relates to an electricity free multi-planar air purification apparatus mounted on a vehicle.
B) BACKGROUND OF THE INVENTION
[002] With the development of industries, the urban population growth, and surge in motor vehicles, a substantial increase in pollutant emissions and suspended solids is deteriorating the air quality. In order to improve the quality of everyday life, people often choose to use air purifiers to clean the air around, but these purifiers are primarily used for household purposes. [003] In present scenario few law air purifiers are also built to clean a citywide air but largely require multiple infrastructure in various parts of the city to provide optimal results. Such a technology has very high cost of operation and installation and also requires experienced staff to operate. In order to eradicate the immobility problem, the prior arts such as CN205836463U provide an outdoor air purifier based on motor vehicles, including clarifier casing, air intake and air exit, clarifier casing one side bottom is equipped with the air intake, clarifier casing opposite side upper end is equipped with the air exit, air intake and air exit are connected to on the inside scavenge port of car of vapour car trunk department reservation through the pipe, air intake department is equipped with pre filtering net, the inside compound airstrainer of multilayer that is equipped with of clarifier casing attracts the outside air to get into and can change

according to the concrete environment in the external world the intelligent fan
of wind -force with being used for, the clarifier casing is equipped with the
power, the power -on is crossed the dc -to -ac converter and is linked to each
other with car power supply, be connected with automatic power protection
devices on the power, the intelligence fan links to each other with the power
through automatic power protection devices.
[004] But these vehicle-mounted air purifiers are largely dependent on
electricity to provide air purification. The usage of electricity in the vehicle
further adds to use of fossil fuel which adds to pollution and hence results in a
zero-sum advantage.
[005] In the view of foregoing, there is a need for an electricity free, multiplanar
air purification apparatus mounted on a vehicle for efficient purification of
outdoor air.
[006] The above-mentioned shortcomings, disadvantages and problems are
addressed herein, as detailed below.

F) DETAILED DESCRIPTION OF THE DRAWINGS
[0027] In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. The embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.
[0028] FIG. 1 illustrates a side view of an air purifying apparatus mounted on top of a vehicle, according to one embodiment of the present invention. With respect to FIG. 1, the apparatus comprises an air inlet unit, a pressure multiplier 102, a filter unit 103, and an outlet unit 104. The air inlet unit is installed in front end of the said apparatus in a direction of movement of the vehicle 100. The pressure multiplier 102 is a hollow chamber installed behind the air inlet unit.

The filter unit 103 is detachably attached behind the pressure multiplier 102. The outlet unit 104 comprises an air outlet and a water outlet attached behind the filter unit in a superimposing manner. The said apparatus comprises a housing 105 with a plurality of serially arranged interconnected compartment for housing the air inlet unit, the pressure multiplier, the filter unit and the outlet unit respectively.
[0029] FIG. la illustrates a side view of an air inlet unit in the purifying apparatus, according to one embodiment of the present invention. With respect to FIG. la, the air inlet unit comprises a horizontal air inlet channel 101a and a vertical air inlet unit 101b. The vertical air inlet unit 101b is attached behind the horizontal air inlet unit 101a. The vertical air unit 101b comprises a primary fan 106, a mover fan 107 and a passage channel 108. The primary fan 106 is exposed to air through an opening in a top surface of the housing 105. The passage channel 108 creates an outer periphery of the primary fan 106 and guides an air flow towards the pressure multiplier 102. The primary fan 106 and the mover fan 107 are connected through a common shaft 109 and separated by the passage channel 108. The mover fan is provided in a path of the horizontal air inlet channel.
[0030] A kinetic motion of the vehicle is used for forcing air inflow in the horizontal air inlet channel and further to the pressure multiplier to increase a pressure of air falling on the filter unit. The increased air pressure leads to cleansing of higher volume of air per unit time. A kinetic motion of the air flowing through the horizontal air inlet channel rotates a mover fan leading to

rotation of the common shaft and the primary fan respectively. The rotational motion of the primary fan leads to suck-in of an air from vertical direction. The sucked in air is guided to the pressure multiplier through the passage channel. [0031] An exemplary functioning of the said air purifying apparatus is calculated hereforth. If the vehicle is moving at a speed of 50Kmph and an inlet cross-section of the horizontal and vertical air inlet unit combined is 10 sq.m, then a volume of 140 cu.m/second is sucked in through the vehicle without using an electricity. Thus, in a day, the vehicle is able to purify an air volume of 1.2*107 cu.m. which is higher than any currently used air purifiers technologies. [0032] FIG. 2a, 2b and 2c illustrates a top view, a side view and a front view of a filter unit in the air purifying apparatus respectively, according to one embodiment of the present invention. With respect to FIG. 2a-2c, the filter unit comprises a primary coarse filter, a secondary fine filter, a high efficiency particulate air (HEPA) filter and an activated carbon filter. The primary coarse filter is a G3 class filter which helps to reduce pollutants more than size of 5 micrometer with a performance of 80% to 90% efficiency. The secondary fine filter is a F8 class filter and helps to reduce pollutants more than size of 1 micrometer with a performance of 90 to 95% efficiency. The high efficiency particulate air (HEPA) filter is a HI3 class filter and helps to reduce pollutants more than size of 0.3 micrometer with a performance of 99.95% efficiency. The filters are washable in nature and can be used until damaged. The activated carbon filter is used for removing harmful gases such as chlorines, VOC's Volatile Organic Compounds, etc.

G) ADVANTAGES OF THE INVENTION
[0033] The present air purification apparatus provides compact, mobile and
highly efficient air purification technology without utility of an electricity. Thus,
no extra fuel is used for air purification. Further, due to removable and compact
filter units, the installation and operational cost of the present apparatus is very
low as compared to contemporary technologies.
[0034] Additionally, the present apparatus is installable over a range of vehicle
from 4-wheeler to 8-wheeler, hence can be deployed in any terrain and
geographical location.
[0035] The present invention uses fan assemblies, hence in case of peak hours
where a driving speed is low, the air suction can be created through movement
of the fan optionally driven through usage of an electricity. Hence, the present
invention still provides a larger running period and lower electricity
consumption.
[0036] It is to be understood that the phraseology or terminology employed
herein is for the purpose of description and not of limitation. Therefore, while
the embodiments herein have been described in terms of preferred embodiments,
those skilled in the art will recognize that the embodiments herein can be
practiced with modification within the spirit and scope of the claims.
