Exhaust gas is often generated when the mechanical device is activated. The exhaust gas needs to be discharged to ensure the normal operation of the mechanical device. Therefore, various exhaust devices are gradually developed for installation in the machine. On the device, the exhaust gas is guided and filtered, and the vibration is further absorbed to avoid noise. The exhaust pipe of the prior art mainly comprises an outer pipe; a hollow mesh pipe having a plurality of holes and passing through the outer pipe; at least one intake pipe penetrating inside the mesh pipe and having an intake end for exhaust gas An air outlet cover is disposed at a rear end of the outer tube and penetrates to form an air outlet; at least one air outlet is axially disposed in the network tube and has one end connected to the air outlet cover An air outlet; and a sound-absorbing cotton, which is disposed outside the network tube and located between the outer tube and the network tube for filtering and silencing. Thereby, when the exhaust gas flows from the plenum through the intake pipe, it can flow back along the air outlet cover and the inner wall surface of the outer pipe at the air outlet cover, and finally flows out from the air outlet pipe, thereby preventing the exhaust gas flow rate from being too fast and generating vibration. However, when the exhaust gas is recirculated, some of the kinetic energy is lost from the gas outlet, so that the carbon deposits in the exhaust gas are deposited in the exhaust pipe M329678, forming a blockage, and the waste body is in the gas outlet cover. When the exhaust port discharges the exhaust gas, it will directly discharge other places due to the position of the exhaust port. [New content] The main purpose of this creation is to provide a "bottom exhaust type &", which can make the internal exhaust gas recirculate, so that the exhaust gas can be saturated and silenced, and it is easier. Exhaust gas after recirculation. For the above purposes, the "bottom exhaust pipe" of the present invention includes: P - an outer pipe having a first end and a second end; to > an intake pipe which is disposed through the outer pipe One end, the exhaust gas is allowed to enter the outer tube; to; an air outlet pipe, which is disposed at the second end of the outer tube for exhaust gas discharge; and is characterized in that the outer wall surface of the outer tube is inclined The bottom is provided with a bottom, and the bottom is formed with a flow passage communicating with the inner chamber of the outer tube. • the air outlet cover is disposed at the second end of the outer tube, and an air outlet is formed, the air outlet is a closed or open-through type; and, when the exhaust gas flows into the outer tube from the air inlet tube, It can be recirculated on the inner wall of the outer tube and finally flows out from the outlet pipe, thus causing a regular circulation effect, so that the exhaust gas is easy to be saturated, and the flow velocity of the exhaust gas can be prevented from being too fast to generate vibration, thereby achieving the effect of silencing. Wherein, the exhaust gas that loses kinetic energy after the recirculation can flow out from the bottom pipe by gravity, thereby preventing carbon deposits in the exhaust gas from being deposited in the exhaust gas to ensure the unblocking of the exhaust pipe, and using the bottom pipe to increase the discharge The amount of gas, or the outlet is closed, so that the exhaust gas is directly discharged from the bottom pipe. [Embodiment] M329678 Please refer to the fourth figure, the present invention provides a bottom row exhaust & 'which is directly or indirectly fixed to an exhaust gas generator such as a steam engine, an internal combustion engine or a fuel engine (not shown) And a gas port (not shown) connected to the exhaust gas generator to discharge the exhaust gas. The bottom row exhaust pipe system comprises: an outer pipe (1 〇), a sound-absorbing cotton (2 〇), a mesh pipe (30), an intake cone cover (4 〇), and an intake pipe (50) An air outlet cover (60) and an air outlet pipe (70), wherein: the outer pipe (10) has a first end and a second end, and a bottom pipe (Η) is disposed obliquely on the bottom outer wall surface thereof. The bottom tube (1〇 is formed with a flow passage communicating with the inner chamber of the outer tube (10); the mesh tube (30) is a hollow tube body having a plurality of holes and passing through the outer tube (10) The sound-absorbing cotton (20) is hollow tubular, and is sleeved outside the mesh tube ((10)), so that the sound-absorbing cotton (20) is inserted between the outer tube (丨〇) and the mesh tube (3〇) to form a three-layer tube. The intake conical cover (40) is disposed at the first end of the outer tube (10), and a sealed plenum is formed by a first partition (41); the intake tube (50) Between the network tube (3〇), which is inserted into the first partition (41) of the inlet cone opening cover (40), and has an inlet end electrically connected to the plenum, and An outlet end is located inside the network tube (3〇) · The air outlet cover 60) Covering the second end of the outer tube (10), and forming an air outlet (61), the air outlet (61) is a closed or open-through type; the one-out rolling tube (70) The shaft is axially disposed in the network tube (3〇), on both sides of the air outlet end of the air inlet tube (50), and the outer sleeve is provided with a second partition plate (71) located at a middle portion of the outer tube of the M329678. The second partition (71) forms another plenum; when the exhaust gas enters the intake cone cover <4〇) and concentrates on the plenum, it can flow into the outer tube via the intake pipe (50) (丨〇 ); since the intake pipe (50) is not in line with the air outlet pipe (7〇), the exhaust gas discharged from the air outlet end of the air intake pipe (50) will hit the air outlet cover (6〇) The inner wall surface causes the exhaust gas to flow back along the wall surfaces of the first partition plate (41) and the second partition plate (71) at the gas outlet cover (6〇), so that the reverse circulation is used to make the exhaust gas easy to be saturated, and finally through the gas outlet pipe (7〇) flows out from the air outlet (61) or the bottom tube (11). In addition, it slows down the flow rate of the exhaust gas, avoids vibration and further achieves the effect of muffling. At the same time, it can continue to flow around because of the irregular collision of most of the exhaust gas, so it is easy to let the oil and gas be absorbed by the muffler cotton (20), and achieve a more environmentally friendly effect. The exhaust gas that loses kinetic energy after recirculation can flow out from the bottom official (11) by gravity, thereby preventing carbon deposits in the exhaust gas from depositing in the exhaust pipe to ensure the bottom exhaust pipe of the present creation. Unblocked. In summary, the bottom row exhaust pipe provided by the creation can solve the above-mentioned deficiency of the conventional use, and can achieve the above-mentioned effects, and has the progressive improvement of the industrial use and the improvement of the efficacy. In line with the new patent requirements, according to the patent law, please submit a request, please review and give the patent as soon as possible, it is a pray.
