Abstract

A device is disclosed for treating an exhaust gas emanating from a vehicle engine or a plant's chimney. This device has a housing having a treatment chamber defined therein, an inlet port for receiving an exhaust gas to be treated, and an outlet port for releasing a treated gas. The gas is allowed to flow in the treatment chamber from the inlet port to the outlet port defining a flowing direction. The device further has treating elements in the treatment chamber which are layers of rocks of granite alternating with layers of rocks of charcoal. The layers extend substantially in perpendicular to the flowing direction of the gas.

Description

EXHAUST GAS TREATING DEVICE
FIELD OF THE INVENTION
The present invention relates generally to the art of exhaust gas filtration and more particularly to the cleaning of exhaust gases of an engine or a chimney.
BACKGROUND OF THE INVENTION
Pollution from the exhaust of vehicles or plant's chimneys has caused serious air quality problems. Moreover, it is a well known fact that such pollution is a major factor of the "greenhouse" effect. It is also a well known fact that vehicle and plant's chimneys exhaust are both major causes of poor air quality, especially in large and industrial countries.
Many of such countries have adopted environmental policies in order to improve the air quality. For instance, certain governments have strongly suggested the use of unleaded gasoline and firmly required the use of catalytic converters for vehicles.
2 0 Furthermore, the governments have set up environmental protocols and restrictions to decrease air pollution emanating from plant's chimneys. However, these policies, protocols and restrictions have not completely resolved the .air pollution problem.
Known in the art are devices for filtering exhaust gas emanating from an engine or chimneys of industrial plants that have been also used in order to improve the air quality. Examples of such prior art devices are described in US patents nos.
5,209,912; 6,074,620 and 6,185,934 B1. While these devicEa have resulted in the advancement within the present field, most of these prior art devices have not been successful or sufficiently efficient to filter the exhaust gases emanating from these sources.
Therefore, there is still a need for an improved device for filtering exhaust gases of an engine,or a plant's chimney.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved device for treating an exhaust gas.
In accordance with the invention, that object is achieved with a device for treating an exhaust gas, the device comprising:
- a housing having a treatment chamber defined therein, an inlet port for receiving an exhaust gas to be treated, and an outlet port for releasing a treated gas, the gas being allowed to flow in the treatment chamber from the inlet port to the outlet port defining a flowing direction; and - treating means in said treatment chamber comprising layers of granite containing material alternating with layers of carbon-containing material, said layers extending substantially in perpendicular to the flowing direction of the gas.
The present invention is also directed to a combination of a first and a second device 2 o as defined above. The combination comprises connecting means for fluidly connecting the outlet port of the first device to the inlet port of the second device.
The present invention also proposes a method for treating an exhaust gas, comprising the steps of:
2 5 a) providing a device as defined above;
b) feeding the inlet port of the device with an exhaust gas;
c) treating the exhaust gas in the treatment chamber; and d) releasing from the outlet port of the treatment chamber a treated gas.
30 A device for treating an exhaust gas according to the present invention proposes innovative features that makes it compact and easy-to manufacture and use.
More importantly, the device of the present invention makes it possible to treat exhaust gas in a simple and efficient way. As a matter of fact, an important feature of the device resides in that layers of granite disposed between each layers of charcoal help reducing the temperature of the gas flowing in the treatment chamber. Such a reduction in the gas temperature will prevent the charcoal used to filter the exhaust gas from accelerated damage.
BRIEF DESCRIPTION OF THE DRAWINGS
1 o The present invention and its advantages will be more easily understood after reading the following non-restrictive description of a preferred embodiment thereof, made with reference to the following drawings wherein:
Figure 1 is a schematic view of a device for treating an exhaust gas according to a preferred embodiment of the invention.
Figure 2 is a perspective view of a device for treating an e~:haust gas according to another preferred embodiment of the invention.
2 o Figure 3 is a schematic cross-sectional view of the device o~f figure 2.
DESCRIPTION OF PREFERRED EMBODIMENTS
2 5 The present invention is directed to a device for treating an exhaust gas.
By "treating an exhaust gas" as that term is used therein, it is meant trE:ating either through a chemical and/or a physical process. However, a particular advantageous treatment process in which the device of the present invention may find application is in the field of filtration of exhaust gas emanating from motorised vehicles, such as cars, 3 0 motorcycle, trucks, snowmobiles, boats or the like. The device of the present invention may also be used for treating polluted air emanating from a chimney of an industrial plant.
Referring to Figure 1, the device (10) for treating an exhaust gas of the present invention comprises a housing (12) having a treatment chamber (14) defined therein.
The housing (12) also comprises an inlet port (16) for receiving an exhaust gas to be treated, and an outlet port (18) for releasing a treated gas. The gas is allowed to flow in the treatment chamber (14) from the inlet port (16) to they outlet port (18) defining a flowing direction indicated with the arrows in figure 1. Furthermore, the device (10) of the present invention comprises treating means in the treatment chamber (14).
Such treating means comprises layers of granite-containing material (20) alternating l0 with layers of carbon-containing material (22). As it can be seen in figures 2 and 3, the layers (20, 22) extend substantially in perpendicular to the flowing direction of the gas. In order to keep the layers (20, 22) substantially perpendicular to the flowing direction of the gas, it may be preferable, though not essential, to separate each layers (20, 22) with a mesh-like material (26). Preferably, the layers of granite-containing material (20) comprise rocks of granite, whereas the layers of carbon-containing material (22) may be charcoal or any other type of coal preferably made in the form of rocks.
In a situation where the device (10) of the present invention is used to treat exhaust gas emitted by a vehicle engine, the rocks of granite (20) have preferably a diameter of approximately 3/ inch and the rocks of charcoal (22) preferably have a diameter ranging approximately from '/2 to 1 inch. Each layers of both granite (20) and charcoal (22) have preferably 6 ounces of material.
2 5 As can be appreciated, the important feature of the device (10) resides in that layers of rocks of granite (20) help reduce the temperature of the gas flowing in the treatment chamber (14). Such a reduction in the gas temperature prevents the rocks of charcoal (22) used to filter the exhaust gas from accelerated damage. Thus, by alternating layers of granite (20) and charcoal (22), it was surprisingly found that while the treatment of the exhaust gas was proceeding, the treating capacity of the rocks of charcoal (22) was maintained and prolonged over time.

According to a preferred embodiment, the housing (12) rnay comprise ventilating means for ventilating the treating chamber (14). Preferably, the ventilating means comprises an air conduit (28) in fluid communication with the treatment chamber (14). For instance, when the device (10) is used on a motorised vehicle, the device 5 (10) is preferably installed at the back of the vehicle or moue preferably the farthest from the engine so that the heat coming from the engine does not damage the device (10). On such situation, the flow of air is provided when the vehicle runs at high speed. Therefore, the air flow enters through the air conduit (28).
Alternatively, in order to propel or inject the air through the air conduit (28), the latter (28) may have an air inlet (30) adapted to be fluidly connectable to <~ fan outlet (not shown).
in this case, a 12 volt motor with a fan (similar to a car heater) is preferably used, but any other kind of air blower known to one skilled in the art may be used.
The flow of air provided into the air conduit (28) is preferably controlled by a control means which may comprise a heat sensor linked to a fan controller in order to maintain the temperature inside the device (10) of approximately between 160 ° and 170 ° F when the engine is running slowly or in the case that the outside temperature is substantially hot. In such a case, the heat sensor is preferably and operatively connected to the inlet port of the device (not shown). Preferably, the air blower starts when the temperature inside the device (10) is between 120° to 140° F.
Advantageously and as shown in figures 2 and 3, the device (10) of the present invention may also comprise a reception chamber (32) upstream from the treatment chamber (14). As best viewed in figure 3, the reception chamber (32) is in fluid communication with the treatment chamber (14) and comprises regulating means for regulating the flow of exhaust gas before treatment in the treatment chamber (14).
In such a case, the exhaust gas to be treated enters through the inlet (42) of the reception chamber (32). The regulating means comprises a plurality of baffle walls (34) disposed in a way to split the exhaust gas into flows of gases.
Therefore, the gases are then forced to meet prior entering in the treatment chamber (14).
Such a contact will result in a substantial decrease of the gas temperature.
Moreover, the contact of these flows of gases will also get rid of some of the impurities contained in the exhaust gas. The reception chamber (32) may also rave an indirect role of reducing or muffling the sound produced within the device (10) of the present invention.
Referring back to Figures 2 and 3, the present invention is also directed to a combination of a first (10a) and a second (10b) device as defined above. The combination further comprises connecting means for fluidly .connecting the outlet port (18) of the first device (10a) to the inlet port (36) of the second device (10a). It will be understood that any type of connectors or fasteners known to one skilled in the art will suffice. It is preferable that the second device (10ib) comprises regulating l0 means for regulating the flow of gas in its treatment chamber (14). The regulating means of the second device (10b) are preferably downstream from the treatment chamber (14) and upstream from the outlet port (38) of the second device (10b). The regulating means of the second device (10b) comprises at least one baffle wall (40).
These baffle walls (40), as seen in figure 3, are disposed in a way to force the contact of the gas before its release through the outlet (38) of the second device (10b). As mentioned above, the contact of the gases will .get rid of the remaining impurities, if any, contained in the treated gas.
According to another aspect of the present invention, a method for treating an exhaust gas is proposed. The method comprises the steps of:
a) providing a device (10) as defined above;
b) feeding the inlet port (16) of the device (10) with .an exhaust gas;
c) treating the exhaust gas in the treatment chamber (14); and d) releasing from the outlet port (18) of the treatment chamber (14) a treated 2 5 gas.
The method may comprise the additional step of ventilating the treatment chamber (14). Advantageously, the method may also comprise prior to step b), a step of regulating the flow of exhaust gas.
According to a preferred embodiment, the method may further comprise after step d), the step of treating the gas released in step c), in another device (10b) as defined above. In such a situation, it may be preferable that the method comprise the step of regulating the flow of gas in the second device (10b).
