The present invention relates to an exhaust gas purifier that removes air pollutants contained in the exhaust gas by flushing the exhaust gas emitted from the internal combustion engine and the heat exchange engine into water. As this type of exhaust gas purification apparatus, the contents described in Japanese Patent Application Laid-Open No. 57-62909 or Japanese Patent Application Laid-Open No. 60-233311 have already been known.

The exhaust gas purification device has a structure that does not sufficiently mix the exhaust gas and water in the use process, the purification efficiency is very low, and when the output power is weak, such as exhaust gas through the automobile's muffler, the exhaust gas is suppressed. There was a problem of stopping this. In order to solve this invention, an exhaust cleaner of Korean patent publication 92-2654 (Application No. 90-7774) has been proposed.

Such an exhaust purifier is provided with a water pipe in which the exhaust gas is blown in the water tank, and in the water pipe, a plurality of water suction holes for sucking water in the water tank are provided, and inside or outside the water pipe. This is done by installing a screw to forcibly drain the water sucked from the suction hole into the water tank in the water pipe.

When the water in the water pipe is forcedly drained into the water tank with a screw, the water in the water tank is sucked into a plurality of water suction holes in the water pipe so that the water in the water tank circulates in the water pipe and the water tank.

Since the inside of the shroud pipe becomes negative pressure by suction of water from the water suction hole, the exhaust gas can be forced into the water flow pipe. Since the water sucked into the water pipes in the plurality of water suction holes sucks the exhaust gas into a plurality of long and thin water streams in the water pipe, the mixing of the exhaust gas and the water is performed very efficiently. In addition, the mixing of the exhaust gas and the water is also performed by stirring with a screw, and moreover, during the circulation in the water tank when draining into the water tank in the water pipe. However, such an exhaust gas purifier is not easy to manufacture due to the complicated internal structure, and simply configured to pass the exhaust gas through the process in the process of sucking water, so that the mixing state of the exhaust gas and water is not efficient.

In order to solve the various problems of the related art, the water tank of the water tank is sprayed toward the movement direction of the exhaust gas, the filter body of the water tank connected to the exhaust pipe is driven, and the exhaust pipe connected to the filter body is the water tank. Connected via.

According to the present invention, the mixed state of the exhaust gas and water is mixed very well, and the centrifugal force of the rotating filter body reduces the noise while simultaneously removing the contaminants from the filter when inhaling and discharging the exhausted water. Exhaust gas is released in the removed state, and noise pollution is significantly reduced. Next, the present invention will be described in detail with the accompanying drawings. In the exhaust pipe (90), a purifying silencer (100) consisting of a water tank chamber (300) and a purifying chamber (200) is installed.

The purification chamber 200 is configured to be connected to the water tank chamber 300 in a superimposed state, the filter body 210 made of one or more layers of filters 201 inside the drive motor 220 and Installed together, the filter body 210 may be horizontally rotated by the rolling friction member 202 and the motor 220 used as a power generating member. One end of the power generating member connected to the filter body 210, that is, the shaft 221 of the driving motor, is fixed to the filter body 210, and the other end protrudes to the outside of the driving motor 220. To be fixed at the tip.

The pulley 222 of the power generating member hangs one side of the belt 223 and hangs the pulley 234 of the pump 23, which is a water suction member for fixing the other side of the belt to the outer surface of the purifying silencer 100.

The power required to drive the drive motor 220, which is the power generating member in the above, it is preferable to use a power source for the automobile, but other separate power source may be used.

The water tank chamber 300 includes a large semicircular portion 301 extending from the bottom surface of the filter body 210 to both sides and a small semicircular portion 302 extending from both side surfaces of the filter body 210 to the upper surface. In this water tank 300, the injection pipe 331 is installed at a suitable position on the upper surface and the drain pipe 332 is installed at a suitable position on the bottom surface to fill the water through the injection pipe 331, and from the exhaust gas to the drain pipe 332. Selective drainage of filtered contaminated water with air pollutants.

In addition, the suction pipe 231 of the pump 230 installed on the outer surface of the water tank chamber 300 is immersed in the water filled in the large semicircular portion 301 of the water tank chamber 300 and discharged to spray the water in an atomized state. The pipe 232 is inserted into the gas flow path through the exhaust pipe 90 connected to the purification chamber 200 so that the injection port 233 of the discharge pipe 232 faces the exhaust gas moving direction horizontally.

The exhaust pipe is connected to the first exhaust pipe 310 on one side of the upper surface of the large semi-circle portion 301 on the upper side of the small semi-circle portion 302 of the purification chamber 200, and the second exhaust pipe 320 is also on the other side of the upper surface of the water tank chamber 300. ) Is a preferable configuration to form a see-through window 303 in a portion of the water tank chamber 300 in order to easily determine the amount of water and the degree of contamination of the water.

In the drawing, reference numeral 223 is a fastening element for fixing the power generating member, a fastening element for fixing the pump 230 to the purifying silencer 100, and 224 is a sealing packing for the connection part of the filter body and the power generating member. to be.

According to the present invention having the above configuration, the motor 220 and the pump 230 are applied to the power generating unit together with the start of the vehicle or driving of the heat exchange engine while the water W is filled in the water tank chamber 300. Driven. By the driving, the filter body 210 is rotated in the small semi-circle 302 of the purification chamber 200 to generate centrifugal force, and an oil film is formed between the water W and the surface of the filter body 210, and the pump ( 230 sucks the water (W) through the suction pipe 231 to move to the exhaust pipe 90 side and sprays through the discharge pipe 233 in the exhaust pipe.

Therefore, since the exhaust gas passes through the water film sprayed while passing through the exhaust pipe 90, the exhaust gas is sucked into the through holes drilled into the filter by the centrifugal force of the filter body 210 which is mixed with the water and rotates.

At this time, since the exhaust gas passes through the filter balls in a zigzag manner, the air pollutants contained in the exhaust gas have a higher specific gravity than the gas, so that the gas passes first, and the polluted water is passed through the filter body 210. You will be filtered out of the water.

Gas passing through the filter body 210 is moved to the first exhaust pipe 310 by the gas pressure increasing in the purification chamber 200 and flows back into the water tank chamber 300 and along the first exhaust pipe 310. Noise is lowered by discharge from the water flux (W), the gas rises over the water due to the light weight of the specific gravity, and then flows into the second exhaust pipe 320 and is discharged.

In this exhaust process, pollutants in the exhaust gas are filtered by the filter and the water, and the noise is significantly reduced by the oil film and the water when the filter body rotates, and the exhaust gas is clean and quiet.

Since the temperature of the exhaust gas is high, there is a heat exchange action when passing through the water membrane and when passing through the filter, so that the water retains heat indirectly, and water vapor is filled in the water tank. The addition of water to the material occurs naturally.

The water addition action improves the pollutant removal function, and the exhaust gas is further purified, and the pollution level of the water can be checked through a viewing window from the outside of the water tank to maintain the water exchange time. By opening the flow path and the flow path of the inlet pipe to remove the contaminated water and storing the new water, it is simple to install and operate, so anyone can handle it without having to acquire advanced technology.
