As described above, the number of the partition plates is not limited to two, and may be three, four, five, or the like, as long as sufficient cooling of the hot gas is ensured.
An intake conduit 112 and an exhaust conduit 114 are in communication with each chamber.
Specifically, the intake conduit 112 extends through the top wall into the main chamber 1281 and adjacent to the bottom wall. Through such setting, can guarantee that glowing gas fully mixes in the coolant liquid of main cavity 1281, realize the cooling.
Further, a first branch air duct 1231 and a second branch air duct 1232 are provided in the coolant tank 121. One end of the first air-dividing duct 1231 is communicated with the first auxiliary chamber 1282, and the other end extends into the first auxiliary chamber 1282 and is close to the bottom wall; one end of the second branch air duct 1232 is communicated with the second auxiliary chamber 1283, and the other end thereof extends into the second auxiliary chamber 1283 and is close to the bottom wall.

The level of the coolant in each chamber is detected by the level detector 160, and the coolant in the coolant tank 121 is preferably maintained at 75% or more of the volume thereof. When the coolant in the coolant tank 121 is less than 75% of the solvent, the coolant needs to be replenished into the coolant tank 121.
Referring to fig. 3, the bottom wall of the cooling liquid tank 121 is provided with three liquid inlet holes 125 and three liquid outlet holes 126. The three liquid inlet holes 125 and the three liquid outlet holes 126 are respectively in one-to-one correspondence with the main chamber 1281, the first auxiliary chamber 1282 and the second auxiliary chamber 1283. By providing the liquid inlet holes 125, the interior of each chamber is replenished with the cooling liquid.

The bottom of the liquid storage tank 131 is communicated with a liquid conveying pipe 133, and three liquid distributing pipes 134 are arranged at the end part of the liquid conveying pipe 133 far away from the liquid storage tank 131. One end of the three liquid distribution pipes 134 is communicated with the liquid conveying pipe 133, and the other end is respectively communicated with the liquid inlet hole 125 positioned in the main chamber 1281, the liquid inlet hole 125 positioned in the first auxiliary chamber 1282, and the liquid inlet hole 125 positioned in the second auxiliary chamber 1283.

Referring to fig. 1 and 4, the control device includes an electronic control unit 170. Preferably, the electronic control unit 170 may use an in-vehicle computer (ECU).
The temperature detector 140, the three-way solenoid valve 151, the two-way solenoid valve 152 and the water level detector 160 are electrically connected to the electronic control unit 170.
When the temperature of the gas in the exhaust pipe 111 detected by the temperature detector 140 is normal, the opening of the three-way electromagnetic valve 151 communicated with the exhaust pipe 111 is opened, and the gas is exhausted into the atmosphere through the exhaust outlet of the exhaust pipe 111; when the gas temperature in the exhaust pipe 111 detected by the temperature detector 140 is too high and is incandescent gas, the temperature detector 140 transmits a temperature signal to the electronic control unit 170, the electronic control unit 170 controls the opening of the three-way electromagnetic valve 151 communicated with the air inlet guide pipe 112 to be opened, the flow of the incandescent gas into the exhaust pipe 111 is blocked to avoid damage or fire, the incandescent gas enters the cooling liquid tank 121 through the air inlet guide pipe 112 and is fully cooled by the cooling liquid under the action of the plurality of gas dispersers, and the cooling gas enters the exhaust pipe 111 through the exhaust guide pipe 114 and then is discharged into the atmosphere.
As the hot gas passes through the coolant tank 121, the coolant inside thereof is consumed. When the water level detector 160 detects that the cooling liquid in the cooling liquid tank 121 is insufficient and transmits the detected water level signal to the electronic control unit 170, the electronic control unit 170 controls the opening of the two-way electromagnetic valve 152, and the cooling liquid is replenished into the cooling mechanism 120 through the replenishing mechanism 130.
As described above, the installation position of the liquid storage tank 131 is higher than the installation position of the cooling liquid tank 121, so that when the two-way solenoid valve 152 is opened, the cooling liquid in the liquid storage tank 131 can supplement the cooling liquid in the cooling liquid tank 121 by gravity, thereby ensuring that the cooling liquid tank 121 has sufficient cooling liquid and ensuring the normal and continuous operation of the device 100 for eliminating the incandescence gas in the exhaust pipe.
In summary, the device 100 for eliminating the hot gas in the exhaust pipe according to the embodiment of the present invention blocks the hot gas in the exhaust pipe 111 and then cools the hot gas by the cooling liquid, thereby rapidly cooling the hot gas. In addition, the device 100 for eliminating hot gas in the exhaust pipe has the characteristics of rapid temperature reduction, small volume, high reliability and low cost, and is suitable for being widely used in the field of internal combustion engines.
The internal combustion engine of the embodiment of the invention can effectively avoid the situation that the hot gas is accumulated in the exhaust pipe 111 by using the device 100 for eliminating the hot gas in the exhaust pipe, thereby avoiding the damage to the hot gas and the risk of fire.
