Description

AN APPARATUS FOR CONTROLLING EXHAUST GAS EMISSION
EARLIEST PRIORITY DATE:
This Application claims priority from a patent application filed in India having Patent Application No. 202141041621, filed on September 15, 2021 and titled “AN APPARATUS FOR CONTROLLING EXHAUST GAS EMISSION”
FIELD OF INVENTION
Embodiments of a present disclosure relate to controlling emission of exhaust gas, and more particularly to an apparatus for controlling exhaust gas emission.
BACKGROUND
Exhaust gas emission is an emission of exhaust gas generated as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, coal, or the like. Exhaust gas is emitted from entities such as vehicles, factories, industries, household chimneys, and the like. Moreover, industrialization and urbanization have intensified environmental health risks and pollution, especially in developing countries. Prior to emitting the exhaust gas into the external environment, the exhaust gas may have to be purified to prevent environmental pollution, and hence the exhaust gas emission may have to be controlled. There are multiple approaches implemented to reduce pollution caused by such entities. The multiple approaches include amine scrubbing, regenerative carbon dioxide removal, minerals and limestone, positive crankcase ventilation, catalytic convertor, and the like.
However, such multiple approaches possess multiple limitations. In one such approach where the catalytic converter is used, the materials used are platinum and rhodium which are very expensive, thereby making such an approach very expensive. Also, in such an approach, the minimum operating temperature is about 400 degrees Celsius to about 500 degrees Celsius, which is not efficient for short rides within the city limits.
Similarly, a few of such other approaches use algae for filtering exhaust gas which requires time, high temperature, moisture, and suitable atmospheric and geographical conditions to be maintained to breed, thereby making such approaches time consuming, less efficient, and less reliable.
Hence, there is a need for an improved apparatus for controlling exhaust gas emission which addresses the aforementioned issues.

Embodiments of the present disclosure relate to an apparatus for controlling exhaust gas emission. As used herein, the term “exhaust gas emission” is defined as an emission of exhaust gas generated as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, coal, or the like. In one embodiment, the exhaust gas may include carbon dioxide (CO2), nitrogen (N), water vapor, carbon monoxide (CO), nitrogen oxides, or the like. Prior to emitting the exhaust gas into external environment, the exhaust gas may have to be purified to prevent environmental pollution, and hence the exhaust gas emission may have to be controlled. Further, the apparatus described hereafter in FIG. 1 is the apparatus for controlling the exhaust gas emission.
FIG. 1 is a schematic representation of an apparatus (10) for controlling exhaust gas emission in accordance with an embodiment of the present disclosure. In an embodiment, controlling the exhaust gas emission may include purifying an exhaust gas, controlling a pressure of the exhaust gas, controlling a temperature of the exhaust gas, and the like. Further, controlling the exhaust gas emission may be important because the exhaust gas may be emitted from an operation of an entity such as, but not limited to, industries, factories, two-wheeled vehicles, four-wheeled vehicles, railways, trucks, and the like which are important assets and found in a majority in most parts of the world. Furthermore, controlling the exhaust gas emission may also be important because excessive emission of harmful gases into the atmosphere may affect stability of the environment causing several dreadful health issues to living creatures on earth.
Moreover, for controlling the exhaust gas emission from the entity, the exhaust gas may have to be passed through the apparatus (10), and hence the apparatus (10) may have to be attached or coupled to the entity. Thus, the apparatus (10) includes an inlet component (20) including a plurality of orifices. The plurality of orifices includes one or more inlet orifices (30) and one or more outlet orifices (40). The inlet component (20) is adapted to receive the exhaust gas via the one or more inlet orifices (30) upon the operation of the entity when the inlet component (20) is mechanically coupled with an exhaust emission unit of the corresponding entity. The inlet component (20) is also adapted to pass predefined quantity of the exhaust gas via each of the one or more outlet orifices (40) to regulate the pressure of the exhaust gas.
Basically, in an embodiment, the pressure of the exhaust gas may be regulated based on a variation of one or more dimensions of an orifice via which the exhaust gas may be passing. In one exemplary embodiment, the one or more dimensions may include diameter, area, volume, length, or the like. In one embodiment, the inlet component (20) may be composed of first predefined material. In one exemplary embodiment, the first predefined material may include at least one of stainless steel, steel, ceramic, glass, and the like.
Further, upon receiving and passing the exhaust gas through the inlet component (20), the exhaust gas may have to be filtered. Thus, the apparatus (10) also includes a filtering component (50) mechanically coupled to the inlet component (20) at the one or more outlet orifices (40). The filtering component (50) includes a plurality of chambers (60) arranged in a predefined manner. In one embodiment, the plurality of chambers (60) may be arranged parallelly to each other. In another embodiment, the plurality of chambers (60) may be arranged by maintaining a predefined distance between each of the plurality of chambers (60). Each of the plurality of chambers (60) is adapted to receive and hold at least one of a plurality of types of filtering material (70). Each of the plurality of types of filtering material (70) is adapted to filter the exhaust gas received from the inlet component (20) upon passing the exhaust gas through the plurality of types of filtering material (70).
In one embodiment, the plurality of types of filtering material (70) may include at least one of ceramic honeycomb, activated carbon, zeolite, filter paper, and the like. In one exemplary embodiment, the filtering component (50) may filter the exhaust gas by eliminating or adsorbing one or more first type of particles upon passing the exhaust gas through the ceramic honeycomb, wherein the ceramic honeycomb may be placed in at least one of the plurality of chambers (60). In such embodiment, the one or more first type of particles may include pollutants, suspended materials, and the like.
Similarly, in one exemplary embodiment, the filtering component (50) may filter the exhaust gas by eliminating or adsorbing one or more second type of particles upon passing the exhaust gas through the activated carbon, wherein the activated carbon may be placed in at least one of the plurality of chambers (60). In such embodiment, the one or more second type of particles may include carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons, volatile organic compounds (VOC), and the like. Also, in such embodiment, the activated carbon may eliminate or adsorb the one or more second type of particles because of microporosity and a large surface area of the activated carbon.
Also, in one exemplary embodiment, the filtering component (50) may filter the exhaust gas by adsorbing one or more third type of particles upon passing the exhaust gas through the zeolite, wherein the zeolite may be placed in at least one of the plurality of chambers (60). In such embodiment, the one or more third type of particles may include nitrogen. Also, in such embodiment, the zeolite may include microporous aluminosilicate minerals.
The filtering component (50) also includes at least one filter blanket (80) forming an inner lining of a lateral surface of the filtering component (50) for enveloping the plurality of chambers (60). The at least one filter blanket (80) is adapted to filter the exhaust gas when the exhaust gas escapes through one or more edges of the plurality of chambers (60), thereby controlling the exhaust gas emission.

In addition, in one exemplary embodiment, the apparatus (10) may include a cooling component (as shown in FIG. 2) positioned between the one or more outlet orifices (40) of the inlet component (20) and the filtering component (50). The cooling component may be adapted to reduce temperature of the exhaust gas received from the inlet component (20) by lowering velocity of one or more gas particles of the exhaust gas. In one embodiment, the cooling component may be a stainless-steel hose. Also, in an embodiment, the cooling component may be flexible. In one embodiment, the velocity of the one or more gas particles may be lowered by increasing a cross- sectional area of the cooling component. In another embodiment, the velocity of the one or more gas particles may be lowered by increasing a length of the cooling component and making the cooling component flexible enough to bend. In yet another embodiment, the velocity of the one or more gas particles may be lowered using a switch or a valve, wherein an operation of the switch or the valve may be controlled via an external controlling unit.
FIG. 2 is a block diagram representation of an exemplary embodiment of the apparatus (10) for controlling the exhaust gas emission of FIG. 1 in accordance with an embodiment of the present disclosure. Suppose a factory ‘A’ (90) is willing to use the apparatus (10) for controlling the exhaust gas emission via a chimney (100) of the factory ‘A’ (90). Thus, the factory ‘A’ (90) may purchase the apparatus (10) and attach the same to the chimney (100). Basically, the inlet component (20) of the apparatus (10) is attached to the chimney (100) via the one or more inlet orifices (30). As the exhaust gas from the chimney (100) is made to pass through the one or more inlet orifices (30), the exhaust gas gets divided into multiple paths, hence the pressure is regulated. Then, as each of the one or more outlet orifices (40) of the inlet component (20) is attached with the filtering component (50), the exhaust gas is made to pass through the filtering component (50) upon the division of the exhaust gas into the multiple paths. Prior to passing through the filtering component (50), the exhaust gas is made to pass through the cooling component (110). Therefore, upon controlling pressure, cooling, and filtering the exhaust gas received from the chimney (100), a clean gas is released into the atmosphere.
FIG. 3 is a schematic representation of an apparatus (10) for controlling exhaust gas emission in accordance with another embodiment of the present disclosure. The apparatus (10) includes one or more components (120) mechanically coupled with each other via a predefined coupling mechanism. In one embodiment, the one or more components (120) may be composed of third predefined material. In one exemplary embodiment, the third predefined material may include stainless steel, steel, ceramic, glass, or the like. The one or more components (120) may include a pressure regulating component (130). The pressure regulating component (130) may include at least three orifices. The pressure regulating component (130) is adapted to receive exhaust gas via a first orifice (140) of the at least three orifices upon the operation of the entity, when the pressure regulating component (130) is mechanically coupled with the exhaust emission unit of the corresponding entity. The pressure regulating component (130) is also adapted to regulate the pressure of the exhaust gas upon dividing passage of the exhaust gas by allowing first quantity of the exhaust gas to pass through a second orifice (150) of the at least three orifices and second quantity of the exhaust gas to pass through a third orifice (160) of the at least three orifices.
In one exemplary embodiment, the at least three orifices of the pressure regulating component (130) may be positioned by making a predefined angle with each other, thereby allowing the exhaust gas to divide into the first quantity and the second quantity. In one embodiment, the predefined angle may include about 45 degrees to about 120 degrees. Also, in an embodiment, the second quantity of the exhaust gas may be larger than the first quantity of the exhaust gas. Basically, in one embodiment, the second quantity of the exhaust gas may be larger than the first quantity of the exhaust gas because a cross-sectional area of the third orifice (160) may be greater than a cross-sectional area of the second orifice (150).
Moreover, in an embodiment, as the first quantity of the exhaust gas is made to pass through the second orifice (150), the pressure within the apparatus (10) may reduce, thereby preventing backfire of the exhaust gas due to high pressure.
The apparatus (10) also includes the filtering component (50) mechanically coupled to the pressure regulating component (130) via the third orifice (160) of the at least three orifices. The filtering component (50) includes the plurality of chambers (60) arranged in the predefined manner. Each of the plurality of chambers (60) is adapted to receive and hold at least one of the plurality of types of filtering material (70). Each of the plurality of types of filtering material (70) is adapted to filter the exhaust gas received from the third orifice (160) of the at least three orifices upon passing the exhaust gas through the plurality of types of filtering material (70). The filtering component (50) also includes the at least one filter blanket (80) forming the inner lining of the lateral surface of the filtering component (50) for enveloping the plurality of chambers (60). The at least one filter blanket (80) is adapted to filter the exhaust gas when the exhaust gas escapes through the one or more edges of the plurality of chambers (60), thereby controlling the exhaust gas emission.
Subsequently, in one exemplary embodiment, the second orifice (150) may be provided with at least one partial filtering unit (not shown in FIG. 3). The partial filtering unit may be adapted to filter the first quantity of the exhaust gas partially when the corresponding first quantity of the exhaust gas is passed through the second orifice (150). In one exemplary embodiment, the partial filtering unit may include a parts per million (PPM) filter.
Additionally, in one exemplary embodiment, the one or more components (120) may also include the cooling component (110) positioned between the third orifice (160) of the at least three orifices and the filtering component (50). The cooling component (110) may be adapted to reduce the temperature of the exhaust gas received from the pressure regulating component (130) by lowering the velocity of the one or more gas particles of the exhaust gas. Also, in an embodiment, the predefined coupling mechanism may be defined as a mechanism used for coupling the one or more components (120) with each other using one or more coupling means. In one exemplary embodiment, the one or more coupling means may include one or more screws, one or more bolts, one or more nuts, and the like.
FIG. 4 is a schematic representation of an exemplary embodiment of the apparatus (10) for controlling the exhaust gas emission of FIG. 3 in accordance with an embodiment of the present disclosure. Suppose a user ‘A’ (170) is willing to use the apparatus (10) for controlling the exhaust gas emission via a silencer (180) of a vehicle (190) of the user ‘A’ (170). Thus, the user ‘A’ (170) may purchase the apparatus (10) and attach the same to the silencer (180). Basically, the pressure regulating component (130) of the apparatus (10) is attached to the silencer (180) via the first orifice (140) of the at least three orifices. As the exhaust gas from the silencer (180) is made to pass through the pressure regulating component (130), the exhaust gas gets divided into two paths, hence the pressure is regulated. Then, the exhaust gas received is made to pass through the third orifice (160) of the at least three orifices where the filtering component (50) is attached. As the exhaust gas is also made to pass through the second orifice (150) of the at least three orifices, the pressure is reduced within the apparatus (10), thereby prevent backfire due to high pressure. Prior to passing through the filtering component (50), the exhaust gas is made to pass through the cooling component (110). Therefore, upon controlling pressure, cooling, and filtering the exhaust gas received from the silencer (180), a clean gas is released into the atmosphere.
Various embodiments of the present disclosure enable the apparatus for controlling the exhaust gas emission without resisting a natural flow of the exhaust gas as the passage of the exhaust gas is divided into multiple paths, thereby eliminating backfires and carbon accumulation within the exhaust emission unit. Also, the apparatus works in all temperatures and working conditions, thereby making the apparatus more reliable and more efficient.
Further, usage of the apparatus does not affect an engine, transmission, efficiency, and performance of the entity using the corresponding apparatus. Moreover, the apparatus can be used not only for vehicles but also for chimneys of factories, industries, household chimneys, and the like, thereby promoting elimination of pollution worldwide.
