Automobile Exhaust Sediment Filtration Purifier

The present invention relates to a vehicle exhaust gas purification apparatus, and in particular to propose a sedimentary filtration vehicle exhaust gas purification apparatus.

Air Pollution from Excessive Use of Fossil Fuels Air pollution, especially from automobile emissions, has emerged as a problem of human survival beyond the stage of local air pollution. Global warming as a result of air pollution; Ozone depletion, El Niño (sea water temperature rise) are appearing; This is causing disasters such as droughts, floods and heavy snowfall.

However, the estimated emissions of harmful gases released into the atmosphere are expected to increase over the years, increasing by 50% in the year 2000. Regarding such a series of forecasts and measures to protect the global air environment, the emission regulations of the Air Conservation Act, which will be applied in the 2000s to industrialized countries through international agreements, are significantly strengthened than the current emission regulations. Can be seen.

As a series of measures in this regard, Korea is expected to regulate the emission standards of cargo trucks based on passenger cars after 1998.

Air cleaners and fuel filters, which are conventionally installed in automobiles, are involved in the formation of combustion conditions of fuels; Converters are used to reduce emissions of harmful gases from the exhaust gases after combustion. Converters using platinum catalysts react under high temperatures (500-800 ° C.); An effect of 90% is obtained at a reaction temperature of 800 ° C. Therefore, diesel engines that are low temperature engines cannot use high temperature reaction converters.

On the other hand, as part of the air pollution measures, investment and research on lean burn engines that satisfy both fuel economy and emission gas are being made; No practical output is obtained; Even the NOx catalyst device discharged from lean burn engines is still in the research stage.

The energy consumption efficiency (km / l) of gasoline-powered vehicles is shown in Equation 1.

[Equation 1]

640 (g / l) / 0.866 × HC + 0.429 × CO + 0.723 × CO2

For diesel vehicles, the energy consumption efficiency (km / l) is given by Equation 2.

[Equation 2]

734 (g / l) / 0.866 × HC + 0.429 × CO + 0.723 × CO2

Table 1 shows the worst-case amount of harmful substances contained in vehicle emissions.

TABLE 1

Table 1 shows 8.45g / km for small diesel trucks, 9.9g / km for jeep, and about 30% of the soot of buses and large cargo trucks. Based on these calculations, 2,500g is discharged every 500km for passenger cars, and 6,000g is emitted every 600km for diesel trucks. On average, 10-50% of the above emissions are generated under normal driving conditions.

An object of the present invention is to propose a vehicle exhaust gas purification device to reduce the air pollution by purifying and exhausting the exhaust gas of the vehicle.

Another object of this invention is to purify automobile emissions; It is proposed to purify the exhaust gas in contact with the sedimentation water to deposit the exhaust gas in the sedimentation water with soot.

Another object of the present invention is to propose a vehicle exhaust gas purification apparatus for adding a fiber filter filtration apparatus to a vehicle exhaust gas deposition filtration apparatus.

The present invention is characterized in that the exhaust gas of the vehicle is purified and discharged by the deposition filter.

1 is a conceptual diagram of the purification device of the present invention in which a fiber filter filtration device is added to an immersion filtration device. In Fig. 1 the exhaust gas of the engine 1 of the motor vehicle is provided to the purifier 3 of the present invention through an exhaust pipe 11 and a silencer 2; The exhaust gas is purified by a purifier 3 which removes harmful gases together with soot and is released into the atmosphere.

The purifying device 3 is composed of a dipping filter 4; Furthermore, the fiber filter filter 6 is added to the immersion filter 4, and is comprised.

In FIG. 2, the immersion filter 4 is a device for capturing and removing harmful gases included in the exhaust gas together with soot and depositing particles such as soot in the immersion water 40.

Specifically, the configuration of the immersion filter 4 is installed in the upper portion of the upper and lower split type case 41 is provided with a rotary filter 50 to clean the discharge gas in contact with the immersion water; A sedimentation container 42 for accommodating the filtration sediments by receiving the immersion water 40 in the lower portion is installed.

The deposition container 42 may have a capacity such as a fuel container capacity according to the vehicle type; For example, it is set as a container of 30 L, 50 L, and 60 L.

The upper and lower parts of the case 41 are separated from the flange 43 and connected to open the inside during repair and cleaning; A drain valve 44 is provided at the bottom of the deposition vessel 42 so that the deposition water can be exchanged.

Sedimentation water uses clean river water, constant water, etc., and uses frozen water in winter.

The rotary filter 50 is an aberration type rotary filter in which a blade plate 52 is radially arranged on the hub of the support shaft 51; Supporting at least one rotary filter 50 to the case 41 with a support shaft 51; The blade plate 52 is connected to the flow path 55 connected to the exhaust gas inlet 53 and the exhaust gas outlet 54 and rotated at the discharge pressure of the exhaust gas.

The diaphragm 56 is installed in the flow path 55 end.

In the purifying operation of the immersion filter 4, the exhaust gas is introduced into the case 41 through the inlet 53; The rotary filter 50 is rotated while being discharged to the discharge port 54 through the flow path 55. When the rotary filter 50 is driven, the blade plate 52 pumps the immersion water 40 into the flow path 55; The exhaust gas passing through the flow path is in contact with the pumped water and the blade plate 52.

As such, the contact of the immersion water and the blade plate and the exhaust gas; Harmful gases contained in the exhaust gas are captured and deposited in sediment water together with soot; Car exhaust is purged. The rotary filter 50 separates the case 41 from the flange 43 when maintenance of the flow path 55 is required.

The fiber filter filter 6 added to the immersion filter 4 incorporates a filter element 63 between the two grilles 64 and 65 of the vertically divided case 62 connected by the flange 61. and; Supplying the exhaust gas to the upper vacancy 67 through the introduction pipe 66; The exhaust gas discharge pipe 69 was installed in the lower vacancy 68.

And the exhaust gas first purified in the immersion filter 4 is introduced into the upper chamber 67 and filtered while passing through the filter body 63 at the discharge pressure of the gas; The secondary gas filtered out of the fiber filter is collected in the lower chamber 68 and discharged through the discharge pipe 69.

The filtration filter 63 may be replaced by removing the case 62 from the flange 61 and then replacing the filter medium provided between the two grills 64 and 65; It is to replace the filtration filter 63 when the immersion water replacement by matching the filtration capacity of the fiber filter filter to the immersion water replacement time.

As such, the present invention can provide an automobile exhaust gas deposition filter having an automobile exhaust gas deposition filter or a fiber filter filter to reduce air pollution by automobile exhaust gas; Since the high temperature catalyst is not used, the gas can be commonly used in gasoline engines and diesel engines.
