In addition, for the sake of simplifying the drawings, some known and conventional structures and elements will be shown in the drawings in a simple schematic manner.

As shown in FIG. 1 and with reference to FIGS. 2A to 2B, a preferred water injection exhaust gas processor 100 of the present invention mainly includes a cavity 10, a water injection port 20, an exhaust gas connecting pipe 30, and a partition 40 , A drainage port 50 and an exhaust port 60.

The cavity 10 has a processing cavity 11 and contains a processing liquid (not shown in the figure). The cavity 10 also has a first end surface 12 and a second end surface 13 opposite to each other. The cavity 10 can be, for example, a cylinder, and the material can be a non-rusting material, such as stainless steel or aluminum. The treatment liquid may be an aqueous solution, for example. Of course, it is understandable that in other embodiments, the treatment solution may also be a treatment solution containing other components. For example, these components can effectively treat certain harmful gases (or components) of automobile exhaust. As a limitation of the present invention.

The water injection port 20 is arranged on the first end surface 12 of the cavity 10 and communicates with the processing chamber 11, and the water injection port 20 has a first height H1 relative to the bottom of the cavity 10, and the first height H1 It is preferably 2/3 of the height of the first end surface. Of course, in other embodiments, the height of the water injection port 20 is not limited to this.

The exhaust gas connecting pipe 30 can be, for example, a stainless steel round pipe, one end of which can be connected to the exhaust pipe of a car to receive the input of exhaust gas, and the other end can be inserted into the processing chamber 11, and the insertion part is provided with at least one opening 31. In this embodiment, the exhaust gas connecting pipe 30 can preferably be inserted into the processing chamber 11 from the top of the cavity 10 from top to bottom, and the insertion part of the exhaust gas connecting pipe 30 is provided with only one opening 31, and the opening 31 faces the partition 40.

The partition 40 is disposed in the processing chamber 11 and divides the processing chamber 11 into a first chamber 111 and a second chamber 112. The partition 40 is further provided with a plurality of through holes 41, and the through holes 41 are arranged in a honeycomb pattern and communicate with the first chamber 111 and the second chamber 112. The partition 40 can be used for noise reduction, filtering, etc. The partition 40 can also effectively prevent the treatment liquid (for example, an aqueous solution) in the cavity 10 from shaking from side to side during the driving of the automobile.

The drainage port 50 is disposed on the first end surface 12 or the second end surface 13 adjacent to the bottom of the cavity 10, and is connected to the processing chamber 11. The drainage port 50 can be discharged from the processing chamber when the water is changed.的处理液 (e.g. waste liquid).

The openings 31 (or 31' and 32') are sprayed out to merge with the water for the first time to dilute the toxic gas in the exhaust gas and remove the dust or particles contained in the exhaust gas. At the same time, the tail gas entering the processing chamber 11 can also heat water to form water vapor on the top of the processing chamber 11, and the water vapor can further merge with the entering tail gas for a second time. The tail gas in the water can further pass through the partition 40 for noise reduction and filtration, that is, the third fusion is performed. In this way, the exhaust gas after three fusion treatments can finally be discharged through the exhaust port 60. After being processed by the water injection type exhaust gas processor of the present invention, toxic gases, dust and particles in the exhaust gas of the automobile can be effectively removed, thereby effectively reducing the pollution of the atmosphere by the exhaust gas.

In the present invention, the number of openings 31 (or 31' and 32') on the exhaust connecting pipe 30 (or 30') can also be adjusted correspondingly according to the size of the exhaust pipe or the exhaust volume of different vehicles. /Or size. The aperture of the through hole on the partition 40 can also be adjusted accordingly. These are not meant to limit the present invention.

In addition, in severe cold weather that is likely to cause freezing of the aqueous solution, the treatment liquid (for example, the aqueous solution) in the treatment chamber of the water injection exhaust gas processor of the present invention can be discharged to prevent freezing. At this time, the automobile exhaust gas can still be Exhaust through the exhaust port of the present invention without affecting driving.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention.
