TW487771B - Exhaust gas catalytic converter - Google Patents

Abstract

A combustion engine catalytic converter comprises porous mesh sheet material made of metal fibers having a diameter of about 1-30 microns coated with a catalyst and formed into corrugations, the material having a void volume of preferably about 80-95%. Adjacent sheets have corrugations in one example at 45 DEG C in opposite directions relative to the gas inlet and outlet flow directions. The sheets create turbulence creating a pressure drop across the sheet material and causing exhaust gas to flow through the sheet material interstices in contact with the catalyst in the interstices. The material is light weight, has low mass and exhibits good cold start up heating in less than 1 minute. The pressure drop across the converter, with turbulence in the gas flow, is comparable to honeycomb prior art converter structures exhibiting laminar flow, uses less catalyst, is more efficient and is lighter. Various embodiments are shown employing vortex generators for providing turbulence in addition to the zig-zag corrugated channel orientation or to provide tortuous channel paths for the gas flow to create the desired turbulence.

Of production. All of the aforementioned applications and patents are incorporated herein by reference in their entirety. The catalytic converters currently available for automotive combustion engines are usually about 20 mm and are divided into two basic structures. One structure uses a magnesium-aluminum-oxygen ceramic honeycomb sheet including, for example, Cordierite by Corinite Corporation.

O: \ 63 \ 63i38.ptc Page 7 2001.08.02.007-^ V. Description of the invention (2) Body structure, this kind of harmful structure. The low thermal expansion coefficient to prevent thermal shock damage bamboo materials can be extruded. Xinchen, a parallel duct of material and usually a nested structure includes a number of 40 ducts deposited in the duct through the catalyst, which is turbulent. The turbulence in the duct will be the traditional one in the art. Deep knowledge-the larger pressure drop is not what we expected is about to be overwhelming: the structure of the combustion engine that produces the desired efficiency is lower and the back pressure is the problem of the structure. In this class, the surface of the material = inefficient use of π catalyst. The catalyst is applied to the catheter to reduce the gas-clay contact layer. Because the narrow, straight channels of the monomer will be formed-the catalyst interaction between the moving gas lacks a layer ^ reaching the layer, and the catalyst between the catalyst and the flow is formed to compensate for this unnecessary conversion level. The catalyst converter needs to use 9 Second rate. For example, it usually takes 1180 grams. See the structure of bismuth which is large and heavy. "First, the catalyst carrier includes iron-chromium (Fe-Cr) alloy. Second: Aluminum is used for high temperature and oxygen-containing atmosphere. Forming a reaction as a blessing & reaction at a metal surface temperature of up to 100%; chemical oxide scale: a layer that prevents the alloy from being in the 'm' and along the parallel parallel. The thickness of the general alloy diaphragm is about 40 to 50 micron will cover the wave of the sheet = expected extension of the curved wave sheet and all the waves are wound on the board to have a -vertical h spiral structure. Made-large quantity and quality; into parallel channels. More closely wound the sheet will be and It can be used in the lateral plane to study the structure, and the structure also uses the M / C center, with about δ 0 0 channels. However, laminar flow is used to minimize the pressure drop of the structure.

V. Description of the invention (3) The limitations of the honeycomb structure described in f ^ 2 include the larger mass of one of the carriers (3, 200 μg / L) (which will be converted into a higher thermal mass), The number of towels is reduced, and the high heat quality is not what I expected. A large mass will result in slow exhaust gas conversion. Exhaust gas conversion means that the substance reaches the catalyst coated on the monomer structure t, such as 300. The time required for an operating temperature of 0. This also refers to the cold start time of an engine. Due to its thermal mass, the monomer structure is slowly heated to the required temperature during f. This slow exhaust gas conversion will cause poor catalyst response in flying applications and therefore make poor conversion of certain pollutants such as Nox, non-convertible HC and CO. Contaminants will form during startup and when the catalyst has not reached a critical temperature. Therefore, when the catalyst reaches the operating temperature, the level of pollution in the exhaust gas will be unacceptably high, which obviously cannot meet the demand. The solution by reducing walls = reducing mass has limited effectiveness. The sheet metal thickness is currently limited to about 40 microns. Thousands, the single structure of the catalyst converter of the previous technology-the limitation is its limited active surface 'This is the structure of the internal tomb ridge with a small number of channels, which reduces: :::; . Pressure drop across the length of the converter: =. But the area will increase. Niu and Ting said that the Asian and African people expect that the product is across the structure and the voltage drop between input and output. W Raw soil Non-suspended low At present, the technology is improved by a 20 micron left turbulence enhancer. The technology can also strengthen the reaction or reaction between the catalyst and the gas made of such a thin metal plate in the lateral area. The number of other channels has been increased to use the catalytic converter system per square. Apply a new catalyst coating. Force system will transform the converter structure.

The coated catalyst is -1 yoke in which the catalyst is suspended in water (colloid suspension, fluid suspension) and the metal sheet is immersed in mud. Because the mud must be immersed in a network structure (coating the fibers in the cavity), it must have appropriate wet > behavior. As a little oxide layer on the fiber can provide the required wetting, so the heat treatment system provides a good Wetting characteristics. However, the required wetting can be obtained based on the characteristics of the surplus material without the need for heat treatment, only in accordance with the processing procedure of the fiber sheet and the wetting characteristics of the fiber. In addition, the sheet material must be handled carefully after heat treatment to avoid contamination.

For example, heat treatment of 々C. It is so hard and does not affect the heat treatment of the final shell. This can be done by pressing the sheet together into Figure 2 to form a wave shape. The rectangular or diamond-shaped cylindrical case 4 in Figure 4 has components 8, 10 are q. When these recesses and holes are relatively 34 ° on the sheet 28, For the alignment of the thin plate, this is important in combination with the following devices of FIGS. 1 13 to 18. Among the mud containing catalyst powder, the mud contained in the mud is explained in the introduction of the patents related to the catalyst and the best place in the world. This mud is deposited for example from 1 to 10 micrometers. The electrophoresis procedure for the deposition has been described more fully in the introduction section and incorporated into the present application No. 0 9/1 5 6, 023. Electrophoretic coating is followed by heat and heat treatment to bond the catalyst coating to the fibers. During this heat treatment, the sheet material is heated to about 丨 can be implemented when the catalyst is directly deposited on the fiber, which can provide the required catalyst characteristics when coated on the fiber surface. After that, a single corrugated sheet is combined to a catalyst conversion, such as a static hybrid configuration. These are shown in a steel pipe casing 4 again. The thin plate 28 of 6 can be according to the given implementation conditions, and its outer size can be defined by, for example, the size required for installation in the section 6 thousand. Since the casing section 6 is in one row, the size of the component can be determined. Two four holes 30, 32 and holes are formed at the edge of the hole for further processing in the mold clamping device, which are described in the aforementioned application patent No. 09 / 181,186 to FIG.18. The position and angle of the concave Q are ten when the waveforms to be formed are aligned with the periphery of the sheet.

487771 Case No. 89104266 Amended in the fifth, the description of the invention (out) The thin plate 2 8 of FIG. 6 is processed in the device shown and described in the following FIG. 13 to FIG. 18 to form a waveform 50 in the thin plate 28 to form a component. 1 8 8.

The root and apex extend in a linear direction parallel to the axis 61. The components 24, 26, 54, and 56 in Figs. 3 and 4 are rotated with their shafts 61 at another angle P shown in Fig. 25 with respect to the flow direction 16 of the gas passing through the casing 4 in the figure. The direction of the wavy pattern is consistent with the direction of the axis 61 of the component. Definition The corrugation angle P is the angle between the shaft 61 and the flow direction 16. p is in Figure 25) I is at 0. To 90. Between and in the flow pattern is 45. This means that the waveforms of adjacent components are rotated relative to each other by an angle of 2 p and both are rotated relative to the direction of the corrugated angle p. In the left side of Fig. 25, a channel angle p, preferably at 45 ° with respect to the gas axial flow direction 16, provides that the channels of adjacent sheets are rotated relative to each other by 2? Or 90. . This waveform forms a gas channel that penetrates it. These channels can communicate fluid on the edge of the component at the peripheral surface of the casing 4. The ripple angle $ of the flow can be any desired value according to the given implementation conditions. The gas system flowing into the casing 4 in the direction 丨 6 is immersed in the channel of the component, and then flows out at an angle ρ and then flows into the adjacent component at 90 ° to change the flow direction by 90. .

The honeycomb type and the like of the previous technology The force g system forms a laminar flow so that the pressure drop across the converter is reduced, and the high pressure will cause the loss of gravitational force. In Figure 22 to Figure 27, MEC refers to the invention and uses the above and Figure 丨 2 The wavy mesh-like anti-reverse member structure of the mesh material shown. Preferably, the catalyst "supports on the mesh" includes trapping the% $ in the mesh and coating the catalyst on iron wires or fibers. This may Increasing the surface area of the catalyst exposed to the gas when the gas flow gap is 3, some turbulence is needed in order to make enough gas flow to f = the gap. The increase of the surface area of this catalyst can increase the converter Compared with the honeycomb structure with 400 laminar flow channels per inch in the prior art, it requires less catalyst. This waveform forms a turbulence generator, which allows the flow through the holes of the sheet material. Fluid flow in perfect condition. Turbulence generators are available in quantity, size and spacing The fluid flows through the pores of the reticular material on the entire surface of the reticular material. The flow generator effectively flows the pores of the material, and these pores can be small, with a pore size of 50 microns. Without a turbulent generator, the fluid cannot be effective Ground flow through the pores of the pore material, which is derived from the theory of fluid dynamics.

Increase the thickness of the MEC material, reduce the fiber diameter, And reducing the cavity can increase the surface area. If only 50% of the fiber is completely coated, the exposed surface area is still 2.5 times that of the solid sheet covered with gold. The catalyst converters of the previous technology all provide solid surfaces instead of having Porous material with through holes. In the example, it is assumed that a single substrate of the prior art has a thin plate surface area of about 500 square meters per cubic meter, and the effective area of the MEC material converter with an approximately equal overall size is 25. 0 0 m2 / m3.

Accumulation and an end plug of about 10-20% before the conversion of catalysts used in automobiles is essentially a gas-solid material transfer. Previous technology :: The knife is fast, but it is limited by the flow / and the material transfer in the laminar flow is smaller than that in the converter, which shows that the layer uses the catalyst effectively. In Figure 2, section 6 is the first level of / spring, so it cannot be higher than the material transfer of the laminar flow configuration. The effect of the turbulence and transfer generated by the addition of the $ = wave-shaped component is to achieve the efficiency of the exhaust point conversion medium. The use of higher substances, such as those illustrated in Figures 7 to 8 below, is significant. In addition, or alternatively, a turbulent flow can be generated by a coated iron dipole generator before the exhaust gas switching point. The main advantage of the short exhaust gas switching point and the large, internal, and f-shaped objects is that there is still a high conversion during the operation period reached. The area of the mesh is to allow the less efficient device not to operate in the turbulent flow area. This = the conversion using a single converter flows at a sufficiently low pressure drop to lose the allowance, and the width of the channel is sufficient for the conversion of endurance points.

If the gas enters the space / uniformity of the material, it must be replaced by the gas from the channel area, that is, the channel There must be ~ slight pressure in order to use the main part, that is, the $ medium inside the material. Therefore, it is necessary to obtain the required pressure difference and cause material transfer by generating turbulence. There is no gas circulation between the channels in the ~ monomer. The weight per cubic centimeter of the mesh material forming the component when not coated is generally half of the corresponding standard plastic monomer base (0.5 g / cm3) (0.2 g / cm3). Generally speaking, the reduction is 300 grams. Therefore, the mesh material is much lighter than this kind of single ^. 0 The pressure loss in the monomer increases with the flow of the material, which increases with the flow of the material, while the pressure loss in the waveform MEC structure increases quadratically with the flow of the material due to the characteristics of the turbulence (see figure).

The upper assembly 122 has a bearing 176. The support post 180 is connected to the bearing 176. In addition, the post member wo is mounted on the support member 82. The piston manipulator (not shown) is instructed by the controller to lift to the square assembly 122 during operation. The levers 1 62 and 1 64 are in the open position in FIG. 15. The finger systems of the wave-formed members of the upper and lower groups 126, 128, 158, and 160, are separated by a maximum distance for the thin plate 28, the interval between the crease channels 38, and 42 (Figure u). The fingers are then placed above the groups 158 'and 160' that engage the crease channel 3 8 (Figures 丨 丨). This positioning is accomplished by placing the notches 30 and 32 (Fig. 6) of the sheet 28 at the ends of each set of protrusions (not shown). At the same time, the controller does not operate the lever motor to keep the levers i 62 and 1 6 4 in the open position. The controller opens a valve to cause the manipulator (not shown) to release a piston (not shown). This piston allows the upper assembly 1 2 2 to fall by gravity. When the assembly 122 reaches the lowest position, the cam pin 172 will rest on the bottom of the bevel 174. At this point, the fingers are fully engaged with the corresponding crease channel sheets 28 ,. Since the distance between the fingers is set to exactly match the thickness of the thin plates 28, the area between the fingers or at the fingers will not cause a compressive load on the thin plate 28 ,. Therefore, during the bending process, no compression deformation of the thin plate 28 will occur at any position between the creases.

The crankshaft rotates the levers 16 2 and 164 from the position in FIG. 16 to another position in FIG. 18. When the stem is rotated, the pins 168 and 170 of FIG. 16 rotate around the pin 166. Since the two ^ # μ distances are not the same, each pin rotates around the pivot 166 with a different angle range. Each of the members 132, 13Q, 158, and 160 engaged with a different pin 168 or 170 is displaced in the direction 156 by the corresponding pin moving toward the center of the finger assembly. The members of the opposite group move simultaneously in opposite directions. On the same day, the cam pin 172 will be inclined due to the weight of the upper assembly. This type of tilting motion will gradually move the upper assembly to the lower assembly gradually until the fingers reach the staggered position in Figure 17. It is a wrong movement.

When the wave direction of the waveform of the friction factor 对 is relatively small with respect to the fluid (in Fig. 25, it means that when the channel is placed outside, it can be found that the porous material is used) will increase the pressure drop. This flat sheet behaves.

The calculation is based on a flow rate of 10 m / s (based on the vacuum tube Circuit) and temperature 700 K are the calculation conditions. These calculations assume that the reaction is limited by the mass transport in the main channel. Because it assumes that the surface area of the internal fibers does not occur during steady-state operation at high catalyst temperatures Therefore, it can be regarded as a more conservative calculation. Due to the high-intensity turbulence, even if the channel size is larger, the MEC conversion of the exhaust gas will be more efficient. The traditional bee-table structure was actually tested on six automobile engines A pressure drop of, for example, 200 mbar is generated and 60. The angle of the waveform is 0 °: a pressure drop of 120 mbar is generated in a mesh device, and the test value is 40 g The average value of the MEC mesh material and the honeycomb structure of 90 grams of catalyst in six automobile units. § The mysterious test is performed on a 5 liter Porsche 9 2 8 v η engine operating at 5 70 0 rpm 'And its operating temperature is 85 ° C.

The channels in Figure 19 are covered with channels with fewer or fewer such adjacent members. 『不 之 + is square in the plan view, and the components 188 are like all the components. They follow the f-fold line in the opposite direction of the staggered f #. The channel of the above device 186 is a phased half-wave structure in a plan view. Formed in different members and along every two'square. The channel system forms a channel, so the channel 21 of the component 188 is opposite to the observer in the opposite direction to the observer and the channels 212, 217, etc. are transmitted in the opposite direction in FIG. 21. All of the catalyst carrier devices 186 are structured from one to the other. The components are all formed by the same channel.

It can be clearly seen in Fig. 20 that j 1 caused by a true film in a linear channel each channel in Fig. 21 has an upper fin 198, one at a time 198 ', and one lower fin 198' ', and so on. As shown in FIG. 20, a part of the lower fin covers one of the other fins in the channel, and it is a mother-177. In the plan view of FIG. 20, the fins completely block each channel along the direction of the vertical paper surface, and The same is true for all channels. Therefore, there is no ^ = fluid path along the length of each channel 66, causing turbulence in the gas flow. Also, each fin in a given channel has an edge adjacent to and adjacent to a channel barrier. : Each hole 200 is to receive a tip 2 2 2 of a corresponding fin.嬖 As shown in Figure J 9 and Figure 20, the tip 222 of each fin extends through a hole \ hole 2 2 2 of an adjacent channel. Therefore, the tips of all the fins will extend through the corresponding holes of the channel and enter the adjacent channel by 200. Thus, each scale is used to roughly match the channel of the component to provide the required twisted fluid path. The wing of each member is approximately independent of the passage of the adjacent member, but each tip 2 2 2 passes through a hole 2000 on a barrier wall shared with the adjacent member and enters the passage of the adjacent member. For example, one of the tips 222 in FIG. 19 passes through the common channel barrier of the members 190 and 192 u 〇 u °
