Description

A purifier in exhaust of diesel engine

The present invention reduces the harmful substances and soot contained in the exhaust gas due to incomplete combustion by passing the exhaust gas purification device of the diesel engine, more specifically, the exhaust gas generated during operation of the diesel engine through a filtration chamber in which water is injected. According to the present invention relates to an exhaust gas purification device of a diesel engine that can prevent air pollution.

In general, the fuel used in diesel engines is low in ignition, and thus the combustion efficiency is also reduced in proportion to the incomplete combustion rate. It contains a large amount of soot.

It is well known that harmful substances and soot contained in the exhaust gas are pollutants that have a serious adverse effect on humans as well as the natural world. Especially, in cities with many diesel fuel vehicles, air pollution is a major cause of air pollution. The exhaust gas of automobiles is pointed out, and accordingly, the pollution degree of the exhaust gas emitted from diesel vehicles is forced to be regulated.

In order to reduce the pollutants in the exhaust gas discharged from the conventional diesel engine, the predominant method is to remove particulate contaminants by installing a filtration device having multiple filter structures in the exhaust pipe through which the exhaust gas passes. For example, a technique is known in which a catalyst device is installed in a passage through which exhaust gas passes to reduce the chemicals in the exhaust gas by reburning the incompletely burned exhaust gas.

However, the related arts, while using a certain amount of time, deteriorates the flow of exhaust gas and causes exhaust noise while losing its original function when foreign matters remain in the filter or when dragging during combustion accumulates in the catalyst device. There was a problem.

The present invention has been devised in view of the above problems caused by the emission of harmful exhaust gas, and its purpose is to provide a diesel engine that can efficiently remove soot and harmful substances in exhaust gas from incomplete combustion of diesel engines. It is to provide an exhaust gas purification device.

The present invention for achieving the above object is to provide a purification cylinder to allow the flow of the exhaust gas to pass through between the tail pipe discharged to the outside from the exhaust pipe from which the exhaust gas is discharged when the diesel engine is started. At least one collecting chamber having a water spray nozzle for sprinkling water in the exhaust gas and a convection chamber through which the exhaust gas containing water is circulated, and a filter is detachably mounted between the collecting chamber and the convection chamber, Combine the cover for collecting the sprinkled sewage in the lower part of the cylinder, but sewage collected through the support plate and the discharge hole formed in the discharge hole for discharging the sewage sewage while separating the collection chamber and the convection chamber on the inner upper portion of the cover to the bottom of the cover In the process of installing a filter network to filter foreign matter, so that the water collected on one side of the cover can be reused It is characterized in that the supply pump for forcibly circulated in the water spray tank and a pressure pump for spraying water at a high pressure on the conduit connecting the water spray nozzle from the water spray tank.

Hereinafter, the exhaust gas purifying apparatus of the diesel engine of the present invention will be described with reference to the accompanying drawings.

1 is a cross-sectional view illustrating an exhaust system of a diesel engine to which a purifier according to an embodiment of the present invention is applied, and FIG. 2 is an exploded perspective view illustrating the purifier, and an exhaust pipe through which exhaust gas is discharged when a diesel engine is started ( A purifying cylinder 10 is formed integrally on the pipe line of the tail pipe 11 'discharged to the outside from 11) to slow down the flow of the exhaust gas.

Inside the purification cylinder 10, at least one collecting chamber 20 having a water spray nozzle 21 for spraying water into the exhaust gas in the order in which the exhaust gas passes, and a convection chamber through which the exhaust gas containing water is circulated. (22) is formed, but between each of the collection chamber 20 and the convection chamber 22, the filter 30 made of a material which does not invade moisture is easily mounted while the exhaust gas containing moisture passes easily. It is.

The cover 40 is coupled to the lower portion of the purification cylinder 10 to be separated and coupled by a plurality of catching hooks 41 to collect the sprinkled sewage, and the collection chamber 20 is provided on the inner upper portion of the cover 40. ) And a support plate 50 having a discharge hole 51 for discharging the sprinkled sewage while separating the convection chamber 22 is installed, and the sewage that has passed through the discharge hole 51 at the lower side of the support plate 50 is covered. In the process of being collected to the bottom of the 40, a filtering network 52 for filtering foreign matter is installed.

One side of the cover 40 is provided with a supply pump 70 for pumping to be circulated in the water spray tank 60 to be recycled to the water to be reused after the water is sprinkled by the exhaust gas, the water from the water spray tank 60 On the pipe line connecting the nozzles 21, a pressure pump 80 for spraying water at high pressure is provided.

In the watering tank 60, it is preferable to form a water level meter 61 and a water supply port 62 so that the amount of water remaining therein can be measured and replenished.

Therefore, the present invention as described above, the pressurized pump 80 for supplying water to the purification cylinder 10 at the start of the diesel engine is operated so that water is sprayed by the spray nozzle 21 in one or more collecting chambers 20. In this state, while the exhaust gas discharged from the engine via the exhaust pipe 11 flows into the collecting chamber 20, the gas flow is momentarily slowed down, and gaseous liquid is mixed by the water spraying action, which is harmful to the exhaust gas. Substances and soot particles are heavier than gas and fall to the bottom, and at the same time, some of them are collected and removed in the course of passing through the filter 30 by the flow of exhaust gas continuously, and in the convection chamber, the exhaust gas is circulated and dehydrated. By passing through the pure gas is purified through the tail pipe (11 ') is discharged to the atmosphere.

Two collection chambers 20 for spraying water into the exhaust gas by the spraying nozzle 21 are preferable, and the sprayed water may be sprayed in a spray form.

Sewage, including harmful substances and soot, separated from the exhaust gas by the sprinkling action, is collected in the cover 40 after the debris and foreign substances are filtered in the process of passing through the filter network 52 through the discharge hole 51 of the support plate 50. When the amount of collected water reaches a certain level, the supply pump 70 installed on one side of the cover is operated to supply the recovered water back to the water spray tank 60.

On the other hand, after the diesel engine is started for a predetermined time, the cover 40 coupled to the lower portion of the purification cylinder 10 is dismantled to disengage the catch ring 41 to separate the support plate 50 and to collect the chamber 21 and the convection chamber. Each filter 30 mounted between the filter 22 and the filter network 52 mounted on the cover 40 is separately washed and reused, and such maintenance is performed at regular intervals according to the start of the engine, thereby purging to a clean state at all times. It could work.

The exhaust gas purification device of the diesel engine of the present invention has the effect of discharging the exhaust gas in a clean state by sprinkling and removing water from the harmful substances in the exhaust gas generated by incomplete combustion and soot. There is also an economical advantage that can be repaired and maintained by operation and reuse of parts.
