Description of the invention (1) The technical field to which the invention belongs The present invention relates to a graphite reducing device, and in particular, to a graphite reducing device for reducing graphite contained in exhaust gas of a diesel engine. Prior Art In recent years, particulate matter (PM) of graphite components contained in exhaust gas of diesel engines has become a major cause of air pollution and therefore a social problem. Catalysts or filters have been used. The device carries out the elimination of factor substances. In this type of device, it is well known that the continuous regeneration type device uses the thermal energy discharged from the vehicle to cause the carbon and the like attached to the surface to fall due to combustion, thereby preventing clogging of the screen mesh and preventing a reduction in function. Generally, in the exhaust gas of a diesel engine, there is a substance that contains an oil component and can turn into soot, and this substance may cause the mesh of the catalyst or the filter to be blocked, thereby reducing the function. Therefore, although the conventional continuous regenerative device is simple to maintain and low in cost, when it is used for a long time, it is impossible to sufficiently burn off the oil when using only the thermal energy discharged from the vehicle, so that the function cannot be prevented from being lowered. Therefore, the main object of the present invention is to provide a device that does not decrease in function even when it is used for a long time, and has a sufficient graphite reduction effect. SUMMARY OF THE INVENTION A device for solving the problem of the present invention is described below. The first is a graphite reduction device, which is characterized by:

The second style tube type for rectification and thermal expansion in the stage, and the third style tube type muffler body which causes thermal changes. In terms of catalysts, fixed honeycomb ceramic filters and fixed steel sieve roll filters can be used by the contact reduction method. The device of the present invention does not reduce its function even when it is used for a long time, and has a sufficient graphite reducing effect. Embodiment An embodiment of the present invention will be described below with reference to the drawings. 558593 V. Description of the invention (4) Figure 1 is a schematic diagram of the device of the present invention. The device of this embodiment is provided with a muffler body 100, a catalyst 200 for removing graphite, and a filter 300 for removing graphite. The inlet side of the exhaust gas is the side, and the outlet side is the rear side. In the case, in the order of the catalyst 200, the muffler body 100, and the filter 300, from the front side to the rear side, and at the same time: on the front side of the catalyst 200, a rectifier plate with a pipe-type opening is provided. In addition, a rectifying heat accumulator 400 ° containing a heat storage material is installed in the outer box 10, and is used as the first straight tube type for the first stage of rectification and thermal expansion. The rectified exhaust gas after the first stage is a non-rectified device, and has a silencing chamber 20 having a sound-absorbing effect; and a second straight tube type rectifying chamber 30 for the second stage of rectification and thermal expansion; and A third tube-type heating expansion chamber 40 that causes a thermal change. The outer box 10 has a cylindrical shape and is made up of carbon fluff sandwiched between irons. The outer box 10 is provided with an inlet port 10a for an inflow pipe 11 for supplying exhaust gas from a diesel engine, and discharged after treatment. The outlet 10b of the L-shaped end pipe 12 from which gas is released. In addition, the reference numerals 1 3, 1 4, 1 5, 1 6 and 17 in the figure are structures for partitioning each part, and use sand fluff to form a heat-shielding effect. The muffler chamber 20 is connected to the inflow pipe 11 and is provided to be connected to a cylindrical stainless steel stamping plate 21. The first inlet cone is 558593 on the inlet side of the inside. 5. Description of the invention (5) A tube type 22 is provided. A narrow passageway is formed from the entrance side toward the opposite side. On the outside of the stamping plate 21, a stainless steel fluff 23 having a sound-absorbing effect and a carbon sheet 24 having a sound-absorbing effect are arranged. A first return pipe 25 that is bent in a zigzag shape is provided between the silencing chamber 20 and the rectifying chamber 30. The rectifying chamber 30 is provided so that the straight pipe 31 is connected to the first return pipe 25. On the inner exit side, a moderate deep draw-type pipe type 32, which is weaker than the deep draw of the first cone-shaped pipe type 22, is arranged. . Between the rectifying chamber 30 and the heating expansion chamber 40, a second return pipe 33 bent in a U-shape is provided. The heating expansion chamber 40 is provided with a second conical tube type 42, a reverse conical tube type 43, and a pressurized heating tube type casing in this order from the inlet side to the outlet side on the inside of the outer tube 41. 44. The deep drawing of the second conical style tube type 42 is stronger than the first conical style tube type 22 and the moderately deep drawing type tube type 32, so that it forms a large angle stylistic shape ratio. The pressure-heated tubular housing 44 is formed with four narrow teardrop-shaped openings 45 on the front side, and the fairing plate 46 is mounted on the outer side from the middle to the rear. Here, the teardrop-shaped opening 45 is formed so that when the entire exhaust gas flowing into the pressurized heating tube-type casing 44 is 100, the exhaust gas is distributed to about 35%. 558593 V. Description of the invention (6) The low-temperature expansion chamber 47 is formed by pressurized heating tube-type casing 4 4 and outer tube 41. In the figure, reference numeral 48 is a high-pressure heating outlet of the pressure-heated tube-type casing 44 and is formed to be smaller than the narrowest part of the second conical tube-type 42. In addition, symbol 49 is an outer tube 4 1 The exhaust gas confluence outlet. The rectifying heat accumulator 400 has a thin ring-shaped stainless steel wire for accumulating the heat energy of the exhaust gas between the rectifying plates 52 having the stern tube type opening 51 as shown in FIG. Material 53, for example, a rectifier plate with a diameter of 1,500 mm and a turn-around portion of about 150 mm is prepared in two pieces, which are assembled at an interval of 300 mm under the counter-cooperation, so that the exhaust gas flows It can change from a certain direction to multiple directions. In addition, the rectifying heat accumulator 400 allows the thermal energy of the exhaust gas to be accumulated and stabilizes the temperature of the exhaust gas introduced into the catalyst 200, so that the thermal reaction of the catalyst can be reached early in response to the heat change of the catalyst. Certainly. Here, the rectifying plate 52 is formed by press working with a die, and has eight duct-shaped openings 51 around the opening 51. The openings 51 change the flow velocity of the exhaust gas, and therefore the rear The entire surface of the catalyst can collide with the exhaust gas without any deviation. Each of the openings 51 is provided with a stirring element 54 which is formed into a spiral shape so that the flat plate is formed into a deep drawing type, and then two spirals are brought close together to form a strong vortex flow. 558593 V. Description of the invention (7) Further, a dispersion surface 5 5 is formed on a central portion of one of the rectifying plates 52. In the case where the diameter of the rectifying plate 52 is made 1500 mm, the dispersion surface 55 becomes 250 mm in height, and an arc surface R40 of R40 is formed on the edge portion. The exhaust gas colliding with the dispersion surface 55 is dispersed through the arc surface 56 formed on the edge, and is introduced around the rectifying plate 52. At this time, the exhaust gas enters the inside of the rectifying heat accumulator 400 through the entire opening portion 51 of the rectifying plate 52. At this time, the opening portion 51 is of a tube type, and because the stirring element 54 capable of generating a strong vortex flow is installed, the exhaust gas passing through the opening portion 51 becomes an accelerated vortex flow, and therefore collides with the heat storage material 53 . Numeral 61 in the figure is the first converter plate having eight tube-shaped openings 51 in the same manner as the rectifier plate 52 in the periphery. Reference numerals 62 and 63 in the figure indicate a second converter plate and a third converter plate having eight openings in the periphery. The second converter plate 62 is arranged further behind the first converter plate 61 and is arranged in front of the rectifying heat accumulator at intervals. The third converter plate 63 is arranged at intervals further than the filter 300. The symbols 71, 72, and 73 in the figure are the first punch plate, the second punch plate, and the third punch plate in this order. The first punch plate 71 is located on the front surface side of the catalyst 200, and the second punch plate 71 is located on the rear surface side of the catalyst 200. 558593 V. Description of the invention (8) Moreover, the third punch plate 73 is located on the front side of the filter 300. The symbol .81 in the figure is the inlet of the graphite reduction device, and 82 is the outlet of the graphite reduction device. Symbol 91 in the figure is a cone-shaped trapezoidal inlet box, 92 is a cylindrical catalyst box containing the catalyst 200 and the rectifying heat accumulator 400, 93 is a cylindrical silencer box containing the muffler body 100, 94 To accommodate the filter box of the filter 300, 95 is an inverted cone trapezoidal outlet box. Next, the function of the above device will be explained. First, when the exhaust gas entering from the inlet 81 passes through the first converter plate 61 and the second converter plate 62, not only the flow rate is sufficiently changed, but also the diffusion is generated, and it enters the rectified heat accumulator 400. The exhaust gas heated by the rectifying heat accumulator 400 diffuses evenly and enters the catalyst 200, so that graphite is removed. Here, because the exhaust gas entering the catalyst 200 cannot be controlled by the temperature change of the exhaust gas by the rectifying heat accumulator 400, it is heated to a certain temperature, the graphite removal effect is excellent, and the function such as mesh blockage can be removed. Reason for reduction. As a result, the catalyst can be used for a long period of time to prevent mesh clogging and maintain its function g. Secondly, the muffler body 100 can basically introduce the heat source of the exhaust gas discharged from the diesel engine, and use the combustion pressure or gas emitted by the diesel engine, so the secondary combustion caused by the heating and expansion of the exhaust gas can achieve more complete The combustion and the increase of the flow rate of pressure and expansion make the non-combustible gas -10- 558593 V. Description of the invention (9) The specific gravity of the body is reduced, which is caused by the acceleration of the flow rate of the exhaust gas path under pressure. The heating rises, so that the graphite contained in the exhaust gas can be further removed through the next process. First, the unrectified exhaust gas flowing from the inflow pipe 11 passes through the first conical tube type 22 in the silencing chamber 20. The exhaust gas transmitted from the multi-manifold pipe to the exhaust pipe 11 is rectified by the first conical tube type 22 and once pressurized by the exhaust pressure. The rectified exhaust gas expands in the anechoic chamber 20. The expanded exhaust gas flows out from the holes of the stamping plate 21 to the outside and becomes unrectified, resulting in a slow flow. It can be silenced when it flows out of the stainless steel fluff 23 and the carbon sheet 24, and then again from the gas through the holes of the stamping plate 21 Go inside. In the rectifying chamber 30, the flow velocity of the unrectified exhaust gas flowing out of the muffler chamber 20 can be reduced. Then, the gas having a reduced flow rate is pressurized by a moderate deep drawing tube type 32 at the outlet portion of the rectification chamber 30, and undergoes a second expansion by the action of heat. That is, the unrectified gas entering the rectifying chamber 30 becomes rectified inside the straight tube 31 for rectifying, and enters the middle-drilling medium deep drawing type tube type 32, which is pressurized here, so the flow speed becomes faster. It is heated and swells. The exhaust gas from the rectifying chamber 30 flows into the second return pipe 33 and enters the heating expansion chamber 40 to be pressurized. The third expansion is performed by the generated heat. -11- 558593 V. Description of the invention (1〇) The expansion is caused by the rectification started by the second conical tube type 42, inverse conical tube type 43, especially through the inverse conical tube type 43. At this time, the flow velocity rises and becomes maximum. Here, the narrowest portion of the second conical tube type 42 is formed smaller than the first conical tube type 22 and the moderately deep drawn tube type 32, so that the exhaust gas can be pressurized to the maximum. Therefore, the exhaust gas becomes heated to the maximum and expands to the maximum. The exhaust gas of the second conical tube type 42 becomes a high temperature to the extent of secondary combustion, so that the non-combustible gas contained in the exhaust gas can be reduced. When this high-temperature exhaust gas passes through the inverse conical tube type 43, the flow speed is further accelerated. Then, the exhaust gas after the flow velocity is accelerated is different from the primary flow that is advanced in the pressure-heated tube-type casing 44 as it is, and a part of it becomes a secondary flow and flows out from the teardrop-shaped opening 45 , And enter the cooled low-temperature expansion chamber 47, the flow rate greatly changes. Due to such a large change in the flow velocity, the exhaust gas is repeatedly heated by the muffler chamber 20, the rectification chamber 30, and the heating expansion chamber 40 to expand under pressure. The primary and secondary streams separated in the heating expansion chamber 40 are accompanied by a thermal change, and are the primary stream of the high-temperature and high-pressure exhaust stream, and are expelled at the same speed as being extruded. . On the other hand, the secondary stream, which is a flattened and flattened exhaust stream with a large thermal change, has a large volume of gas due to expansion, and its flow is slower than the primary stream.

Description of the invention (11) Moreover, the secondary flow can easily become non-rectified. It is rectified by a rectifying plate 46 installed at the exit and then discharged. The exhaust gas heated in the heating expansion chamber 40 is divided into a primary flow and a secondary flow on the way, and merges at the outlet side. When the flow velocity of the primary flow is added, the secondary flow is accelerated, and The exhaust gas merge port 49 is discharged. Here, the pressure of the exhaust gas flowing out from the teardrop-shaped opening 45 to the outside is greatly different from the pressure of the exhaust gas advancing in the pressurized heating tube-type casing 44. Then, when the flow velocity of the primary flow is added, the secondary flow is accelerated, so that the suction effect is started, and as a result, the suction capability of the interior of the combustion chamber of the internal combustion engine is increased. When the intake capacity is increased, the non-combustion ratio is reduced, and the basic combustion of the engine is improved. Nitrogen oxides (NOx, NO, N02), carbon monoxide (C0), hydrocarbons (HC), and particulate matter (PM) etc. are improved. The exhaust gas from the muffler body 100 is removed by the filter 300, and then diffused by the third converter plate 63, and then exhausted from the outlet 82.
