DESCRIPTION OF THE INVENTION: 1. Field of the Invention The present invention relates to a device for eliminating back pressure (甽钍) installed at the end of an exhaust pipe of an internal combustion engine or at the end of a boiler ventilator (or a chimney) and preventing backflow 'In particular, it relates to a device for preventing backflow caused by a back pressure, which eliminates exhaust resistance and reverse flow of exhaust gas, so as to smooth the exhaust gas generated by burning the fuel by operating the inner or the paving, etc. Or the burning efficiency of the furnace. [Prior Art] In general, as the exhaust gas in the smashing: the pollutants that are burnt, the exhaust gas is discharged at a pressure of 3-5 kg/cm 2 and a high temperature and a high pressure of about 6 nautical miles. Therefore, the catalytic device and the muffler must be installed. Device. When exhausting the exhaust gas burned in the above-mentioned machine, a vacuum is formed in the exhaust pipe f (the light is also generated in the sight (4), and a secondary exhaust resistance which hinders the exhaust gas discharge is formed, and when the honeycomb purifier passes through the ternary tree tanning agent, the exhaust gas is exhausted. The flow rate is remarkably lowered to form a secondary exhaust resistance, which is discharged as a multi-segmented spacer when flowing into the damper, and three discharge resistances are formed. In the purely discharged ratchet, as described above, The silence (4) volume is generally designed to be about -20 times the normal displacement (four), so that the resistance is reduced, and the waste gas is smoothly discharged. Therefore, the energy is reduced, about 5, the fuel consumption is increased by 6 and the pollution is increased. There are a variety of techniques. Therefore, it is possible to improve only by smoothly discharging the exhaust gas: improving fuel consumption, improving kinetic energy and heat energy, and in the case of such a boiler, blowing people on the ventilator You are popular, the outside air flows backwards, and the wind enters the inside of the combustion chamber, causing the suspension of steam and nitride generated during the combustion of the incomplete king to stick to the W (four) surface of the heat exchange 5! This situation occurs on the top surface, and the performance of the hot parent converter is degraded and the heat energy is degraded in order to solve the problem. Therefore, various studies have been made to solve the problem. Patent Publication No. -56951 discloses an air flow vehicle row. Money's flow of air caused by the technology and automobile marketing, the streamlined exhaust port body is mounted on the tail pipe, and the low flow rate is formed according to the flow rate of the air flowing through the streamlined body. Jian, the exhaust gas is sucked out quickly, assisting the exhaust. But Τξ: 'From the structural point of view, the main body of such a streamlined exhaust port is mounted on the ήα car, making the structure relatively large and complicated, so that it is not easy to commercialize. An exhaust tail pipe of a main silencer (Silencer) including a vortex generating device disclosed in Patent Publication No. 1998-75223, in which a vortex blade is disposed in the middle of an exhaust pipe to rotate a blade through an exhaust gas, and the blade rotates through the exhaust gas. The same k produces a thirsty flow' to vent, but this instead creates a resistance that hinders the flow of the exhaust gas' and the structure is deformed by heat. Therefore, there is a problem that is substantially unresolved. In the exhaust gas discharge device of the eddy current disclosed in Japanese Patent Laid-Open Publication No. 257874, the front end of the muffling H formed on the listening channel is provided with a pipe for externally and inflow, on which the pipe is placed. The inside of the blade is formed by forming a flow of the external air of the flow into a hole and forming an adjustment plate (such as a gorge) for regulating the inflow of the external air, and the opening degree of the disk throttle valve is consistent. The exhaust passage supplies thirst and is used to eliminate exhaust noise

The fixed pipe 110, the fixed pipe blade, the double exhaust pipe 120, and the heavy exhaust pipe 130 have different diameters, and a double exhaust pipe 120' is disposed outside the fixed pipe 11〇 on the inner side of the fixed pipe 11〇. The fixed pipe blade 112 is provided with a triple exhaust pipe 1 on the outer side of the heavy exhaust pipe 12A, and the structure of each is described in detail below. The above-mentioned fixed pipe blade 112 is disposed on the exhaust gas 〇 or steel = ventilating R extending from the internal combustion engine. 'Compared with the above-mentioned exhaust pipe 1 () or the ventilating cylinder _ portion, the fixed official blade is more prominent to form exhaust gas. The first passage wi has a first venturi 1 (first rtur 1), and the first venturi structure is closer to the end of the exhaust gas, and the area of the passage is reduced. The closer the fixed pipe blade 112 having the above structure is to the end portion of the first passage W1 where the area is reduced, the more the machine is caught. By reducing the exhaust resistance and the large force, the exhaust gas can be exhausted. The wind has a diameter larger than that of the exhaust pipe 10 or the pass: a downward setting without changing the structure of the exhaust pipe 10 or the ventilating cylinder, and a plurality of pressurizing portions inside thereof for forcibly inserting the connecting row The gas officer 10 or the passage is formed along the inner side of the fixed pipe blade 112. The upper air pipe 10 or the fixed pipe material 112 and the official needle 112 and the exhaust air are called 'fixed pipe blades. 'On the exhaust pipe or ventilator' to achieve a secure bond of the fixed pipe blades 112. At this time, the connection hole 132 for fixing the fixing bolt b of the fixed pipe blade m more firmly is formed at a specified position of the triple exhaust pipe (10) (when the triple exhaust pipe 13 is not provided, the connecting hole is formed in the second The heavy exhaust pipe (10) is connected to the exhaust pipe ventilator via the connecting hole 132 to prevent the detachment of the fixed pipe blade 112. The m1G protrudes toward the outer side of the fixed j piece 112 while surrounding the fixed pipe blade (1). The second passage W2 is formed so that the exhaust gas passing through the first passage W1 of the solid-state S blade 112 passes again, and In the second venturi structure V2, the area of the second rhyme W2 is gradually reduced. The diameter D2 of the end of the IU 疋 叶片 blade 112 is larger than the diameter D1 of the end portion of the fixed tube 11 ,, so that the flow velocity of the second passage w2 formed by fixing f 丨丨 G is larger than that formed by the fixed tube blade 112 The flow rate of the first pass (four) rapidly discharges the exhaust gas outward. Due to the above structure, the exhaust gas is quickly discharged to the outside through the venturi and the second venturi formed on the fixed pipe blade (1) and the port g 11G. The above-mentioned heavy exhaust gas g 12 〇 is used to form a third passage W3 ′ for inflowing the counter-current exhaust gas to be disposed on the fixed pipe 11 , so as to surround the outer side of the fixed pipe ιι, and a third venturi is formed. The structure V3, the more the structure is directed inward (i.e., the direction of the row 78 of the trachea 10), the more the area of the first channel milk is reduced, so that the countercurrent exhaust gas (hereinafter referred to as exhaust gas countercurrent) flows more smoothly. The reason why the second venturi is designed as described above is that the exhaust gas recirculation mainly occurs along the side wall of the second gas cylinder (10). Therefore, the above structure is provided for the rapid discharge of the exhaust gas. The inside of the fixed tube 110 (the portion connected to the fixed tube blade 112) is formed at the designated position along the hiding portion to form a shirt side tube flow σ lu, which is used to form a countercurrent flow of the outer wall of the crucible The exhaust gas (ie, "exhaust gas countercurrent,") is also the channel that is also discharged outward, so that the exhaust gas flows backward through the fixed pipe flow port (1) toward the inner 4 of the s 110, and is finally quickly discharged together with the exhaust gas being exhausted. The exhaust pipe 13G to j is spaced apart from the above-mentioned double exhaust pipe, and the periphery of the two exhaust pipes 13 上述 is connected to the opposite side of the protruding pipe 4 of the fixed pipe blade ι 2 around the two rows of pipes. The structure eliminates back pressure to prevent backflow (4). The coffee can be arranged on the end of the exhaust pipe of the internal combustion engine or on the end of the ventilating cylinder. _Steel fine Wei side and fixed pipe haystack, exhaust gas G1 through the fixed pipe blade 112 formed by the first venturi 1335378

On the other hand, the exhaust gas discharged through the fixed pipe blade 112 passes through the end portion of the fixed pipe no 'this time' through the exhaust gas G2 at the end of the fixed pipe 11 在 through the second venturi formed through the creep portion of the fixed official 110 The flow rate is further increased in the V2 region of the structure, and is rapidly discharged to the outside. On the other hand, when the exhaust gas is exhausted, a part of the exhaust gas is inevitably reversed, thereby generating "exhaust gas countercurrent" due to the third venturi formed by the double exhaust pipe 120. The low pressure or vacuum generated by the V3, as described above, is reversed (2) and rapidly moved along the wall of the double exhaust. The thus-moved exhaust gas countercurrent G3 rapidly flows to the inside of the fixed pipe 11〇 through the flow _111 provided on the fixed pipe 110 due to the low pressure or vacuum generated between the fixed pipe blade 112 and the fixed pipe 11〇.

As described above, the present invention is more effectively turned over based on the first venturi (4) of the fixed pipe blade 112, the second venturi structure based on the fixed pipe 11 (4), and the third venturi structure V3 based on the double exhaust pipe. On the way of moving along the inner wall of the double exhaust pipe, the secretary knows that the pipe flow σ(1) enters the inside of the fixed pipe again, and then _bu, from Ke (four) to stop the Wei countercurrent, to improve the combustion efficiency of the 34 or the furnace. The present invention is not limited to the above-described preferred embodiments, and various modifications may be made by those skilled in the art without departing from the scope of the claimed invention, and such modified embodiments are all required. Within the scope of protection. As described above, the present invention eliminates the exhaust resistance of the exhaust gas and the reverse flow of the exhaust gas, and lowers the atmospheric resistance, thereby achieving an improvement in fuel consumption rate and a reduction in soot caused by an increase in combustion efficiency of the internal combustion engine and the boiler, and excellent operation. Performance and maximization of kinetic and thermal energy. Further, in the case where the structure of the end portion of the exhaust pipe of the internal combustion engine or the end portion of the boiler ventilator is not changed, the mounting can be easily performed, thereby improving the interchangeability with various devices.
