The energy pipe 305 includes a first contracting pipe 3051, a first expanding pipe 3052 is installed at one end of the first contracting pipe 3051, a first spray disc 306 is installed at one end of the first contracting pipe 3051, a second nozzle 307 is provided on the bottom surface of the first spray disc 306, a ventilation pipe 5 is installed on the bottom surface of the first spray tower 301, a liquid pipe 4 is installed at one end of the first expanding pipe 3052, a secondary purification device 6 is installed at one end of the ventilation pipe 5, a water supply machine 8 is provided on one side of the secondary purification device 6, and a water supply pipe 7 is installed at one end of the water supply machine 8.

[0027] Based on the above Example 1, please refer to Figure 3 - Figure 7 The secondary purification device 6 includes a second spray tower 601, a second mounting ring 602 is installed on the inner wall of the second spray tower 601, a second annular tube 603 is installed on the top surface of the second mounting ring 602, a third nozzle 604 is provided on the outer side of the second annular tube 603, the inner wall of the second annular tube 603 is connected to the second functional tube 605, the second functional tube 605 includes a second shrinking tube 6051, a second expanding tube 6052 is installed at one end of the second shrinking tube 6051, a second spray disc 606 is installed at one end of the second shrinking tube 6051, a fourth nozzle 607 is provided on the bottom surface of the second spray disc 606, an exhaust pipe 9 is installed on the top surface of the second spray tower 601, and a drain pipe 10 is installed on the bottom surface of the inner wall of the second spray tower 601.

[0028] The inner wall of the bottom end of the second spray tower 601 is interconnected with the inner wall of the ventilation pipe 5. There are two second mounting rings 602, and the two second mounting rings 602 are fixedly installed on the inner wall of the second spray tower 601 at equal distances. The top surface of each second mounting ring 602 is in mutual movable contact with the outer surface of a second annular tube 603, and the outer surface of each second annular tube 603 is provided with a number of third nozzles 604 at equal distances.

[0029] The two second annular tubes 603 are in movable contact with the inner wall of the second spray tower 601, the inner wall of each annular tube is interconnected with the inner wall of a second functional tube 605, the inner wall of each constricted tube is interconnected with the inner wall of a second spray disc 606, and the bottom surface of each second spray disc 606 is provided with a number of fourth nozzles 607 at equal distances.

[0030] The inner wall of each second contracting tube 6051 is interconnected with the inner wall of the second expanding tube 6052, the inner wall of each second expanding tube 6052 is interconnected with the inner wall of a water supply pipe 7, the inner wall of the drainage pipe 10 is interconnected with the inner wall of the second spray tower 601, and the inner wall of the liquid pipe 4 is interconnected with the inner wall of the liquid supply pipe.

[0031] The exhaust gas rising along its inner wall reacts with the seawater sprayed from the second annular pipe 603 and the second spray disk 606, and then continues to rise to the top of the inner wall of the second spray tower 601 and enters the exhaust pipe 9, and then is discharged along the exhaust pipe 9. The seawater inside the first spray tower 301 enters the bottom of the second spray tower 601 along the inner wall of the ventilation pipe 5 and converges with the seawater at the bottom of the second spray tower 601 to enter the drain pipe 10 for discharge.

[0032] The working principle and usage process of the present invention are as follows: when using this high-efficiency ship exhaust gas purification device, the exhaust gas enters the inner wall of the first spray tower 301 along the inner wall of the exhaust pipe 2, and the top of the first spray tower 301 moves downward. At this time, the water supply machine 8 extracts the obtained seawater and transmits the seawater to the water supply pipe 7. The seawater enters the liquid pipe and the first functional pipe 305 and the second functional pipe 605 along the water supply pipe 7. Since the inner wall diameters of the first contracting pipe 3051 and the first expanding pipe 3052 of the first functional pipe 305 are different, the flow of seawater will be accelerated when the seawater flows from the large diameter to the small diameter. The seawater flows through the first functional pipe 305 to the first annular pipe 303 and the first spray disc 306 and is sprayed out through the first nozzle 304 and the second nozzle 307 opened. The sprayed seawater contacts the exhaust gas entering the inside of the first spray tower 301, and the seawater reacts with the substances in the exhaust gas to achieve initial purification.

[0033] The exhaust gas that has completed the initial purification then enters the second spray tower 601 along the vent pipe 5. The exhaust gas rising along its inner wall reacts with the seawater sprayed from the two pairs of second annular pipes 603 and the second spray disk 606, and then continues to rise to the top of the inner wall of the second spray tower 601 and enters the exhaust pipe 9, and then is discharged along the exhaust pipe 9. The seawater inside the first spray tower 301 enters the bottom of the second spray tower 601 along the inner wall of the vent pipe 5 and converges with the seawater at the bottom of the second spray tower 601 to enter the drain pipe 10 for discharge. At this time, the process of high-efficiency purification of ship exhaust gas is completed.
