SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides a muffler 1 formed by a front pipe 3, a muffler main body 2, and a tail pipe 4; Is inserted into the injection opening protruding portion 11 of the tail pipe 4, and the partition plate 16 having the through hole 25 formed therein, the muffler body outer shell rising portion 31, and the tail pipe outer shell 8 are provided.
A tail pipe water storage tank 18 is formed from the tail pipe outer shell rising part 17 and one end of a water supply pipe 20 is inserted into a water supply opening projection 19 located substantially below the tail pipe water storage tank 18, and the other end is connected. The water supply pipe 20 is inserted into the pump
Is branched, and a bubble 22 is installed near the tip of the branch water supply pipe 21. One end of the water sprinkling pipe 15 is inserted into the pump water supply port 29, and the other end is inserted into the tail pipe water injection opening projection 13 in which the perforated plate 14 is fitted.

[0005] The present invention secondly provides the sprinkler pipe 15
Of the perforated plate 1
4 is inserted into the tail pipe water injection opening projection 13 fitted therein. The tip of a branch sprinkler pipe 36 branched from the sprinkler pipe 15 is connected to the muffler main body injection opening projection 3 with the perforated plate 14 fitted therein.
4, a partition plate 16 provided with a through hole 25, and a partition wall 7
The muffler body outer shell 24 and the muffler body outer shell rising section 31 form a muffler main body water storage tank 35, and the muffler body outer shell rising section 31 is provided with a communication hole 33.

[0006]

According to the first aspect of the present invention, high-temperature and high-pressure exhaust gas discharged from an engine (not shown) of an internal combustion engine is supplied from an intake hole 5 of a front pipe 3 to an air chamber 6 of a muffler body 2.
As the pressure is reduced by repeating the expansion and contraction of the water, the water sent from the pump 28 through the water sprinkling pipe 15 flows from the tail pipe injection opening projection 13 fitted with the perforated plate 14 to the tail pipe flow path 32 through which the exhaust gas flows. The inside is sprayed evenly in the form of a mist, and the exhaust gas flowing through the tail pipe circulation path portion 32 is taken as if passing through a shower,
Soot and dust are removed, and harmful substances such as nitrogen oxides and sulfur oxides are dissolved in water, and a cleaner exhaust gas is discharged to the outside air from the discharge holes 12 of the tail pipe 4. In the second aspect of the present invention, since the exhaust gas passes through the mist shower in the air chamber 6 of the muffler main body 2 and the tail pipe circulation path portion 32, water droplets remove soot and dust contained in the exhaust gas, Harmful substances such as nitrogen oxides and sulfur oxides are dissolved in water, but discharge a cleaner exhaust gas from the exhaust holes 12 of the tail pipe 4 to the outside air.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a muffler for an internal combustion engine according to a first embodiment of the present invention; FIG.

The muffler 1 comprises a front pipe 3, a muffler main body 2, and a tail pipe 4. The muffler body 2 is divided into a plurality of air chambers 6 by partition walls 7. Water is poured from the water inlet 9 of the water pipe 10 and the partition plate 1
From the through-hole 25 opening to 6, the liquid flows into the tail pipe water tank 18 formed by the partition plate 16, the muffler body outer shell rising section 31, the tail pipe outer shell 8, and the tail pipe outer shell rising section 17. At the same time as the operation of the engine (not shown) of the internal combustion engine, the pump 28 connected to the generator (not shown) by the cord 27 is operated, and the water supply opening projection 19 of the tail pipe water storage tank 18 is operated. The water in the tail pipe water storage tank 18 is sucked into the pump 28 from the water supply pipe 20 inserted into the pump through the pump water inlet 26, and the water is sent through the water pipe 15 inserted into the pump water inlet 29, and the water is supplied to the water pipe 15. , A tail pipe water injection opening projection 1 fitted with a perforated plate 14 having a large number of fine holes, the other end of which is inserted.
3, the soot and dust of the exhaust gas flowing through the tail pipe flow path portion 32 are removed by spraying the tail pipe flow path portion 32 in the form of mist, or nitrogen oxides, sulfur oxides, etc. It dissolves in water and discharges cleaner exhaust gas to the outside air from the discharge hole 12 of the tail pipe 4. The partition plate 16 is inclined toward the through-hole 25 so that the water sprayed from the tail pipe water supply opening projection 13 in a mist state returns to the tail pipe water storage tank 18 promptly. Through hole 2
5 may be plural. In addition, tail pipe water injection opening projection 13
The perforated plate 14 is fitted to the sprinkling tube 1.
5 may be fitted around the tip.

A second embodiment of the present invention will be described with reference to FIG. The first water sprinkling pipe 15 of the present invention
Is inserted into a pump water supply port 29, and the other end is inserted into a tail pipe water injection opening projection 13 fitted with a perforated plate 14 having a large number of fine holes. The tip of the branch sprinkler pipe 36 branching from is inserted into the muffler main body injection opening projection 34 in which the perforated plate 14 is fitted. Pump 28
Is sprayed from the tail pipe injection opening projection 13 fitted with the perforated plate 14 into the tail pipe flow path 32 through the sprinkler pipe 15 in a mist state, and the water sent from the pump 28 is branched and dispersed. The water also flows through the water pipe 36, and is sprayed into the air chamber 6 from the muffler main body injection opening projection 34 in a mist state to remove soot and dust of the exhaust gas. , And a cleaner exhaust gas is discharged to the outside air from the discharge hole 12 of the tail pipe 4. The partition plate 16 is inclined toward the through-hole 25 so that the water sprayed from the muffler main body injection opening projection 34 in the form of mist quickly returns to the muffler main body water storage tank 35. Depending on the amount of water, a plurality of through holes 25 may be provided. The muffler main body water storage tank 35 and the tail pipe water storage tank 18 are formed with a communication hole 33 that opens to the muffler main body outer shell rising portion 31,
Communicating. Although the muffler main body 2 has a plurality of air chambers 6 with the partition wall 7, it is desirable to provide the muffler main body injection opening projection 34 in the air chamber 6 near the tail pipe 4 where the exhaust gas pressure is smaller. When ammonium or urea is added to the water stored in the tail pipe water storage tank 18 and the muffler main body water storage tank 35, the effect of dissolving nitrogen oxides, sulfur oxides, and the like into water is great. Exhaust gas discharged to the outside air is cleaner.

The water in the tail pipe water tank 18 and the muffler body water tank 35 is circulated and used repeatedly. Then, as appropriate, the bubble 22 provided in the branch water supply pipe 21 is opened, the wastewater is drained from the drain hole 23, and new water is replenished. It is desirable to collect sewage in public places and incinerate or dispose of it by chemical treatment from the viewpoint of environmental problems. The pump 28 may be fixed to the muffler main body 2 by welding or fixed to a chassis (not shown).

[0011]

According to the above, the discharge hole 1 of the tail pipe 4 is formed.
Exhaust gas exhausted from 2 to the outside is washed. The cost is also low.
