Description

Technical Field

[0001] The present invention relates to the technical field of tail gas treatment, in particular to a tail gas treatment device with a self-heating water removal function. Background Art

[0002] When an internal combustion engine is just starting up, the air passing through the engine becomes hot due to the alternation of hot and cold air. After the hot air (commonly known as exhaust gas) flows into the exhaust pipe, the exhaust pipe is still cold because the engine has just started, causing the water vapor in the hot air to quickly condense into condensed water, which is the white smoke we often see coming out of the vehicle exhaust pipe, and a small amount of sewage will also flow out. If the carbon deposits in the exhaust pipe are serious, the sewage flowing out at this time will be relatively black. In this way, the sewage discharged through the exhaust pipe during driving will flow to the ground and cause pollution. If the sewage flows to the ground in cold areas, it will cause freezing, which can easily cause traffic hazards. In addition, due to the cold region, when the car has just started and has not traveled a long distance, the condensed water in the exhaust pipe that has not been completely discharged will flow back and freeze, thereby blocking the exhaust pipe and preventing the car from starting. Summary of the Invention

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figures 1 to 6 Shown:

[0026] A tail gas treatment device with a self-heating dehydration function comprises an exhaust pipe 1 and a condensed water treatment module 2 coaxially arranged at the outlet section of the exhaust pipe 1, the condensed water treatment module 2 is used to evaporate the condensed water discharged through the exhaust pipe 1; the exhaust pipe 1 is also provided with a guide hole 11 at the outlet end thereof, which is connected to the interior of the condensed water treatment module 2; the condensed water treatment module 2 also includes a treatment cylinder 21, which is a hollow cylindrical shell with open ends; an annular cavity for treating condensed water is formed between the treatment cylinder 21 and the exhaust pipe 1; a treatment module 22 corresponding to the guide hole 11 is also provided at the bottom of the inner wall of the treatment cylinder 21 to evaporate the condensed water.

[0027] In the working state, the gasoline in the engine is fully burned, and water vapor and carbon dioxide are generated after the gasoline is completely burned. When the ambient temperature is low, white smoke and water vapor emerge from the exhaust pipe 1. When the water vapor flows through the metal pipe, it will condense into condensed water. Finally, the condensed water flows along the inner wall of the exhaust pipe 1 toward the exhaust port of the exhaust pipe 1. When the condensed water flows through the guide hole 11, the condensed water will pass through the guide hole 11 and enter the condensed water treatment module 2. The condensed water treatment module 2 performs thermal evaporation and removal on it, thereby preventing the condensed water from flowing along the exhaust port of the exhaust pipe 1 to the ground and causing freezing problems.

[0028] See also Figure 4 Shown:

[0029] The guide holes 11 include a first hole group 111, a second hole group 112 and a third hole group 113; the first hole group 111, the second hole group 112 and the third hole group 113 are sequentially opened at the lower end of the exhaust pipe from the far end of the exhaust port of the exhaust pipe 1 to the exhaust port; the first hole group 111 is opened longitudinally along the axis of the exhaust section of the exhaust pipe 1; the third hole group 113 is opened in a horizontal state near the exhaust port of the exhaust pipe 1; the second hole group 112 is densely distributed between the first hole group 111 and the second hole group 112.

[0030] In the working state, the first hole group 111 is an oblong through hole opened longitudinally along the axis of the exhaust pipe 1, and the oblong through holes are arranged at three locations circumferentially along the axis of the exhaust pipe 1 and are all arranged close to the bottom of the exhaust pipe 1. The third hole group 113 is an oblong through hole opened horizontally and arranged perpendicular to the first hole group 111. The third hole group 113 is arranged at two locations along the axis of the exhaust pipe 1. When condensed water is generated in the exhaust pipe 1, the condensed water with a larger flow rate will first be intercepted by the first hole group 111, and then spread toward the second hole group 112 and the third hole group 113 in sequence; until it is intercepted by one of the second hole group 112 and the third hole group 113, all the condensed water generated in the exhaust pipe 1 will be intercepted and diverted into the condensed water treatment module 2. Since the third hole group 113 is arranged horizontally, all the condensed water generated in the exhaust pipe 1 can be intercepted, and the technical problem of condensed water flowing out of the exhaust port can be completely avoided.

[0031] See also Figure 4 Shown:

[0032] The second hole group 112 is a circular through hole and is densely distributed between the first hole group 111 and the third hole group 113 .

[0033] In the working state, the second hole group 112 is provided with multiple groups equidistantly along the axis of the exhaust pipe 1 circumferentially, and the third hole group 113 is used to intercept a small amount of condensed water flowing along the upper wall of the exhaust pipe 1 , thereby achieving all-round interception of the condensed water in the exhaust pipe 1 .

[0034] See also Figures 2 to 4 Shown:

[0035] A drainage hole 211 is formed through the bottom of one end of the treatment cylinder 21 close to the exhaust port of the exhaust pipe 1 , and a connecting element 212 is coaxially welded to the drainage hole 211 ; a sealing knob 213 is screwed to the connecting element 212 .

[0036] In the working state, the connecting element 212 is a nut; when the condensed water enters the treatment tube 21 under the guidance of the guide hole 11, the treatment tube 21 uses the high temperature of the exhaust pipe 1 itself and cooperates with the treatment module 22 to treat the condensed water, and uses high temperature to continuously evaporate the condensed water, thereby realizing how to remove the intercepted condensed water by high-temperature evaporation, preventing the condensed water from flowing out of the exhaust port while realizing how to effectively remove the condensed water.

[0037] See also Figure 5 Shown:

[0038] The processing module 22 includes a pre-processing element 23 and a post-processing element 24; the pre-processing element 23 is fixedly arranged in a vertical state at the bottom of the inner wall of the processing tube 21 and is arranged close to the end away from the exhaust port of the exhaust pipe 1. The pre-processing element 23 is used to perform pre-evaporation treatment on a large flow of condensed water; the post-processing element 24 is fixedly arranged in a vertical state at the bottom of the inner wall of the processing tube 21 and is arranged close to the end of the exhaust port of the exhaust pipe 1; the post-processing element 24 is used to evaporate the residual small flow of condensed water.

[0039] Under the working state, the large flow of condensed water generated in the exhaust pipe 1 first enters the front end of the treatment tube 21, that is, the end away from the exhaust port, under the guidance of the guide hole 11; the condensed water entering the treatment tube 21 first falls on the pre-processing element 23, and the pre-processing element 23 performs preliminary evaporation treatment on a large amount of condensed water, first evaporating and removing a large amount of condensed water, and the water vapor that is not evaporated and removed by the pre-processing element 23 will flow to the subsequent processing element 24 and be removed by the subsequent processing element 24.

[0040] See also Figure 6 Shown:

[0041] The preceding processing element 23 is a fin 231; the fin 231 is longitudinally arranged in the processing cylinder 21 along the axial direction of the processing cylinder 21; multiple groups of fins 231 are arranged circumferentially along the axis of the processing cylinder 21 and are all arranged close to the bottom of the processing cylinder 21; the gap between adjacent fins 231 is greater than the thickness of one fin 231 and less than the thickness of two fins 231.

[0042] In the working state, since the fins 231 are used to increase the heat dissipation area, that is, to increase the contact surface with the air, when the fins 231 are placed in the treatment tube 21, they absorb the heat energy of the exhaust pipe 1 and at the same time greatly increase the heating surface in the treatment tube 21. When the condensed water is conducted to multiple groups of fins 231 and flows down along the fins 231, the evaporation area of the condensed water can be greatly increased, thereby realizing the rapid evaporation and removal of the condensed water and reducing the accumulation of condensed water in the treatment tube 21.

[0043] See also Figure 6 Shown:

[0044] The subsequent processing element 24 is an arc-shaped piece 241 , which is laterally arranged at the bottom of the processing cylinder 21 and close to one end of the exhaust port. A plurality of arc-shaped pieces 241 are equidistantly arranged along the axis of the processing cylinder 21 .

[0045] In the working state, when the condensed water that has not been completely evaporated by the previous processing element 23 is conducted to the arc piece 241, since the arc piece 241 is arranged horizontally and vertically with the previous processing element 23, the condensed water that has not been completely evaporated can be intercepted and evaporated for a second time. When there is a lot of condensed water, it will overflow from both sides of the arc piece 241 and flow to the arc piece 241 behind the current arc piece 241 until the condensed water is completely evaporated.

[0046] See also Figure 6 Shown:

[0047] The surface of the arc-shaped piece 241 is further provided with hydrophobic holes 242 .

[0048] The hydrophobic holes 242 formed on the surface of the arc-shaped piece 241 are used to slowly drain the condensed water intercepted by the current arc-shaped piece 241, so that the condensed water can flow along the hydrophobic holes 242 toward the rear arc-shaped piece 241 at a relatively slow speed, thereby accelerating the evaporation efficiency of the condensed water.

[0049] The present invention can not only intercept and store all the condensed water in the exhaust pipe, but also use the exhaust pipe's own heat energy to quickly evaporate the condensed water, thereby avoiding the technical problem that the condensed water flows to the ground and causes ice and flows back to cause ice, making it impossible for the car to start normally.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
