During the process of starting the internal combustion engine, the air passing through the engine is changed into hot air due to the alternating of the cold and the heat of the air. After hot gas (commonly called tail gas) flows to a tail gas pipe, water vapor in the hot gas is quickly condensed into water vapor because an exhaust pipe is still cold when an engine is just started, namely white smoke is emitted from the tail gas pipe of a common vehicle, and a small amount of sewage flows out. If the carbon deposition of the tail gas pipe is serious, the effluent sewage is black.
Generally, the tail gas pipe of the vehicle is designed at the lower part of the vehicle, so that sewage can directly flow to the ground, but a small number of special vehicle tail gas pipes are designed at the upper part of the vehicle, and the installation of the tail gas pipes is not allowed to exceed the vehicle body, such as an explosion-proof diesel fork lift truck. Then, the sewage at this time flows down onto the vehicle body. In the prior art, an air moisture filter is usually adopted to filter moisture in exhaust gas, however, the existing air moisture filter affects the exhaust gas of the engine more or less, and thus the output power of the engine.

Specifically, the water collector 10 is made of stainless steel and is configured in a cylindrical shape.

The first connecting wall 11 and the second connecting wall 12 are configured to be disposed oppositely, and the intake port 16 is provided on the first connecting wall 11 and the exhaust port 17 is provided on the second connecting wall 12. Specifically, the housing cavity 14 is configured to be cylindrical, and the diameters of the first connecting wall 11 and the second connecting wall 12 are configured to be equal to the diameter of the housing cavity 14.

The exhaust gas pressure flowing through the exhaust passage can be minimized by arranging the bottom of the inlet 16 and the bottom of the outlet 17 to be flush.
A drain port 18 is further provided at the bottom of the housing chamber 14, and the drain port 18 is provided adjacent to the water inlet port and serves to drain the condensed water collected in the housing chamber 14. A pagoda joint 15 is arranged on the water outlet 18, the pagoda joint 15 is used for connecting a drain pipe, and the drain pipe can lead to a sewage collecting container so as to collect and treat sewage.
The inner wall of the second connecting wall 12 is provided with a protruding piece 19, and the protruding piece 19 is formed by the protruding extension of the second connecting wall 12 to the containing cavity 14. The top surface of the tab 19 is configured to be flush with the bottom of the exhaust port 17, and the tab 19 is used to divert vehicle exhaust gas flowing through the exhaust passage.
Referring to fig. 1 to 5, an exhaust gas treatment device according to an embodiment of the present invention includes a water collector 10, an intake pipe 20, and an exhaust pipe 30.
One end of the intake pipe 20 communicates with the intake port 16 and is fixedly connected to the first connecting wall 11. The other end of the intake pipe 20 is adapted to communicate with an exhaust pipe 40 of the vehicle. The connection of the inlet pipe 20 to the first connecting wall 11 may be by welding, screwing, quick plugging, flange connection, etc. Specifically, the intake duct 20 is a cylindrical stainless steel pipe, and the diameter of the intake port 16, the inside diameter of the intake duct 20, and the vehicle exhaust duct 40 are all configured to be uniform.
One end of the exhaust pipe 30 is communicated with the exhaust port 17 and is fixedly connected to the second connecting wall 12, and the other end of the exhaust pipe 30 is used for exhausting the exhaust gas flowing through the exhaust passage. The exhaust pipe 30 and the second connection wall 12 may be connected by welding, screwing, quick-insertion, flange connection, or the like. Specifically, the exhaust pipe 30 is a cylindrical stainless steel pipe, and the diameter of the exhaust port 17 and the inner diameter of the exhaust pipe 30 are configured to be uniform.
Wherein the central axes of the intake pipe 20, the water collector 10 and the exhaust pipe 30 are constructed parallel to each other so that the exhaust pressure of the exhaust gas flowing through the exhaust passage is minimized. Specifically, the area of the first connecting wall 11 (the area defined by the connection of the side wall 13 and the first connecting wall 11) is configured to be 9 to 25 times the area of the intake port 16, and the area of the exhaust port 17 is 1.44 to 2.25 times the area of the intake port 16. A first distance L (the distance from the bottom of the air inlet 16 to the bottom of the receiving cavity 14) is defined between the bottom of the air inlet 16 and the bottom of the receiving cavity 141The distance L between the first connecting wall 11 and the second connecting wall 122Is configured to be a first pitch L11.6-2.6 times of the total weight of the powder. Specifically, the area of the first connecting portion is 16 times the area of the air inlet 16, that is, the diameter of the accommodating cavity 14 is 4 times the inner diameter of the air inlet pipe 2010; area of the exhaust port 17 1.44 times the area of the intake port 16, i.e., the diameter of the exhaust port 17 is 1.2 times the diameter of the intake port 16; distance L between first connecting wall 11 and second connecting wall 122Is a first distance L12.1 times of the total weight of the powder.
The present invention enables the exhaust gas of the vehicle to form an exhaust vortex in the housing chamber 14 when the exhaust gas flows through the housing chamber 14 of the water collector 10 by configuring the water collector 10 to have a specific size, so as to achieve effective collection of the condensed water in the exhaust gas.
When the exhaust gas purification device is used, the air inlet pipe 20 is hermetically connected to an exhaust pipe 40 of a vehicle along the horizontal direction (the axis of the air inlet pipe 20 is parallel to the horizontal line), and when the exhaust gas of the vehicle flows through the air inlet pipe 20, condensed water in the exhaust gas flows together under the driving of the exhaust gas flow; the exhaust gas flows through the inlet duct 20 and into the receiving chamber 14 through the inlet opening 16, and as the exhaust path becomes larger, the exhaust gas flow velocity becomes smaller and condensed water will collect at the bottom of the receiving chamber 14 under the action of gravity.
Meanwhile, when the tail gas flows through the exhaust passage to the exhaust port 17, a small part of the tail gas is blocked by the second connecting wall 12 to change the direction of the gas flow; the part of the exhaust gas will flow toward the bottom of the containing cavity 14, and then flow toward the first connecting wall 11 through the blocking of the bottom wall of the containing cavity 14, and then turn back through the blocking effect of the first connecting wall 11. Under the blocking action of the inner wall of the containing cavity 14, a vortex is formed in the containing cavity 14, and the condensed water collected at the bottom of the containing cavity 14 is driven by the vortex to flow to the water outlet 18 and is discharged from the water outlet 18. The arrangement of the lugs 19 can perform a flow splitting function, thereby promoting the formation of a vortex and preventing condensed water collected at the bottom of the accommodating cavity 14 from being carried away by the exhaust gas flow.
The area of the first connecting wall 11 and the area of the air inlet 16 are set in a specific dimensional relationship, mainly taking into account the influence on the vortex flow in the housing chamber 14. When the area of the first connecting wall 11 is less than 9 times the area of the air inlet 16, the first interval L is made1Too small, so that the vortex generated in the accommodating cavity 14 becomes small, and even the vortex cannot be generated; at this time, the pressure of the air flow generated by the vortex is too low to be beneficial to collecting the condensed water, and the condensed water can be discharged along with the tail gas. When the area of the first connecting wall 11 is more than 25 times the area of the air inlet 16, the first interval L is made to be larger1The vortex generated in the accommodating cavity 14 is increased due to the overlarge size, and the pressure of airflow generated by the vortex is also increased; at this time, the exhaust pressure of the engine will become large, thereby affecting the power output by the engine.
The area of the exhaust port 17 and the area of the intake port 16 are set in a specific dimensional relationship, mainly considering the influence of the superimposed effect of the airflow pressure generated by the vortex flow in the housing chamber 14. After the vortex is blocked by the first connecting wall 11 in the receiving cavity 14, a part of the airflow will flow to the top of the receiving cavity 14. The portion of the airflow, while flowing toward the top of the housing chamber 14, encounters the exhaust airflow flowing from the inlet duct 20 to the housing chamber 14 and follows the exhaust airflow, thereby generating an airflow pressure superposition effect at the inlet 16 of the housing chamber 14. The additive effect of the airflow pressure can increase the exhaust pressure of the vehicle engine, thereby influencing the power output by the engine. When the area of the exhaust port 17 is set to 1.44 times or more the area of the intake port 16 (the inner diameter of the exhaust pipe 30 is set to 1.2 times or more the inner diameter of the intake pipe 20), the exhaust capacity of the exhaust pipe 30 can be made larger than the intake capacity of the intake pipe 20, so that the gas flow pressure superposition effect generated at the intake port 16 disappears at the exhaust port 17. When the area of the exhaust port 17 is set to be larger than 2.25 times the area of the intake port 16, the generation of a vortex flow in the receiving chamber 14 is affected, which is disadvantageous to the effective collection of the sewage.
The distance L between the first connecting wall 11 and the second connecting wall 122At a first distance L from1The specific size relationship is set, and effective collection of condensed water in the tail gas is mainly considered, so that the sewage can be still effectively collected when the vehicle engine is at the highest rotating speed (which means the maximum accelerator in practical use), and the condensed water is not discharged together with the tail gas. The exhaust gas flow is maximum when the engine rotates at the highest speed, the exhaust gas flow speed is higher when the exhaust gas flow is larger in the same pipeline, and the driving force of the exhaust gas flow speed on the condensed water is also maximum; if the condensed water can be effectively collected at this time, the condensed water can be effectively collected at other rotating speeds of the engine. When the distance L between the first connecting wall 11 and the second connecting wall 122Is less than the first interval L1When the length of the accommodating cavity 14 is too short, 1.6 times of the length of the exhaust pipe 30, a part of sewage is discharged by the exhaust pipe. When the distance L between the first connecting wall 11 and the second connecting wall 12 is smaller2Greater than the first pitch L12.6 times of the total length of the tail gas treatment device, the whole tail gas treatment device is too long, and the vortex is not generated; and not only does this waste material costs, take up space, but it may also create sloshing during use.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
