Description

DESCRIPTION
A MIXER
Field of the Invention The present invention relates to a mixer which prevents liquid particles such as fuel and/or urea injected from different points into the exhaust pipes in exhaust systems from sticking inside the pipe and accumulating therein.
Background of the Invention
Today, the mission limit values of some gases for passenger vehicles with gasoline and diesel engine are determined. These gases are carbon monoxide (CO), unburnt hydrocarbon (HC), nitrogen oxide (NOx) and the particles of diesel engines (PM). According to the norms used for emission values, the limit values of the said gases change. Euro norm is the rules identified for limiting the harmful substance production of the automobile manufacturers. As of today there are six identified Euro norms.
In SCR technology, which is also called as "out of engine solution", AdBlue (fuel comprised of urea which is mixed with 32.5% water and developed for regulating exhaust gases) is injected into the exhaust gas coming out of the manifold, and then passes through the catalysts; therefore the level of harmful gas and fly ash is reduced such that it will be in compliance with Euro-4 and Euro 5 norms. SCR technology is based on increasing exhaust gases via urea injected directly into the exhaust pipe coming out of the engine. Ammonium molecules released as a result of vaporization of the water inside the urea released inside the exhaust gas at a high temperature reacts while passing through the SCR catalytic converter and enables the harmful nitrogen oxides to be converted into nitrogen and water vapor which naturally exist in the air. International Patent Document no WO2012089290 (Al), an application known in the state of the art, discloses an apparatus used in distributing the fluids in the exhaust system. There is an injection device in the apparatus. The injection device issues emission in the exhaust line in the inlet of the SCR catalytic converter. With a combination of multiplicity of individual measures, uniform fluid mixtures formed by complete vaporization of exhaust gas and fluids in the exhaust fluids are obtained. In the individual measure, there is at least one swirl generating device or at least one mixing apparatus, catalytic converter and the injection nozzle of the injection device. Injection nozzle is positioned at a predetermined distance on the wall of the exhaust line.
United States Patent Document no US2008250776 (Al), an application known in the state of the art, discloses a mixing apparatus which can be mounted to the cylindrical passage present in exhaust gas circulation. There is an outer and inner regions in the passage. The passage transfers exhaust stream and liquid stream such as urea stream..The mixing apparatus has a retainer ring and the said retainer ring retains the mixing apparatus inside the passage. Fins are provided in the retainer ring. A first plurality of fins imparts rotational velocity component in a first direction to the exhaust stream and urea stream in the outer region of the passage. A second plurality of fins imparts a rotational velocity component in a second direction, opposite the first direction, to the exhaust stream and urea stream in the inner region of the passage.
German Patent Document no DEI 020080291 10 (A 1), an application known in the state of the art, discloses a mixing and evaporating device located in the exhaust gas systems of the . internal combustion engines. The mixing and evaporating device (7) has a ring body (8) which has internal shovels (9). The shovels are fastened with retaining elements (11) in an exhaust gas guiding pipe (10) of an exhaust system at a pipe wall (12). The retaining elements (11) position the ring body. In the above mentioned documents, it is not disclosed a mixer on the surface of which the tab is made, has fins and thus enables the liquid particles to be shattered by being distributed around and which increases the heat transfer area. Summary of the Invention
The objective of the present invention is to provide a mixer which enables the liquid particles to be shattered by being distributed by means of the tabs it has around it and thus enables to increase the efficiency.
Another objective of the present invention is to provide a mixer which is positioned after the injection on any region of the exhaust system.
A further objective of the present invention is to provide mixer which enables to increase the heat transfer area by means of its fin structure.
Yet another objective of the present invention is to provide a mixer which prevents the urea particles from sticking to the pipe wall by being crystallized since its inner temperature is high by means of the fin structure.
Detailed Description of the Invention
"A mixer" developed to fulfill the objective of the present invention is illustrated in the accompanying figures, in which:
Figure 1 is the perspective view of the mixer on the exhaust pipe.
Figure 2 is the perspective view of the mixer.
Figure 3 is the front View of the mixer.
Figure 4 is the lateral view of t ie mixer. The components given in the figures are assigned reference numbers as follows:
1. Mixer
2. Body
3. Fin
4. Tab
P. Exhaust pipe
The inventive mixer (1), which prevents the urea or the fuel sprayed from the injector in exhaust -pipes (P) from sticking to the pipe (P) walls, essentially comprises
at least one body (2),
at least one fin (3) which is positioned in a certain angle on the outer surface of the body (2),
- at least one tab (4) which opens outwards from the outer surface of the body (2).
According to Euro6 norm, pipes (P) with 90 degree angles are placed by being connected inside the pipe (P) in exhaust pipes (P) so that heat loss is not experienced in exhaust systems.
Due to the placement of urea sprayed into the exhaust system in Euro6 systems, 90 degree angle exhaust pipes (P) have to be used. Because of using 90 degree angle exhaust pipes (P), it causes the urea which is injected to stick to the pipe wall while the exhaust gas is turning 90 degree angle corners since it is fast. For this reason, urea injected during this turn is to be protected from exhaust gas.
The exhaust gas is converted into a straight flow circle by means of the fins (3) while the exhaust gas turns around the body (2), and the mixture increases behind the body (2). With the inventive mixer (1), exhaust gas and/or urea generates a rotary swirly flow while passing " around the body (2) by means of its preferably conical structure. The mixture also enters inside the body (2) through the tabs (4) on the outer surface of the body (2) and enables the injected liquid to be distributed mixed and cyclical. The tabs (4) may be inside or outside the circle structure. Furthermore, the tabs (4) may be straight or in a narrowing structure in order to generate circular flow. The number of tabs (4) and fins (3) provided in the body (2) can be decreased or increased in a preferred rate according to the cycle of the flow. The tabs (4) provided on the outer surface of the body (2) enables the fluid to enter inside the body (2) such that it will turn. By this means, it causes the liquid particles to be shattered and the efficiency is increased. Furthermore, by means of the fins (3)' positioned on the outer surface of the body (2), heat transfer area increases and the body (2) becomes hot. The fins (3) are positioned on the body (2) with certain angles. By means of positioning the fins (3) in this way, a complete circle is formed in the flow and thus the mixture becomes perfect.
Since the fins (3) on the outer surface of the body (2) enable the exhaust gas to move by rotating, they also enable the exhaust/urea mixture to be homogenous. By means of the angular tabs (4) provided on the outer surface of the body (2), the exhaust gas enters into the body (2) while rotating, and thus it mixes the urea sprayed from there. While the tabs (4) are pushing the urea out of the body (2), they also enable it to move by rotating and thus efficiency is increased. Since the fin (3) structure transfers heat, the temperature of the body (2) and the inner temperature of the body (2) are high, and high temperature prevents the urea particles from crystallizing.
