Description

Technical Field

[0001] The invention relates to the technical field of hydrogen fuel vehicles, in particular to a waste liquid collection and treatment system for hydrogen fuel engines. Background Art

[0002] A hydrogen fuel engine refers to an internal combustion engine used in hydrogen fuel vehicles. It is generally improved from an existing internal combustion engine and has the characteristics of an ordinary internal combustion engine. The pressure generated by the combustion of hydrogen inside the engine pushes the piston to move, thereby providing power. Existing hydrogen fuel engines rarely use pure hydrogen as fuel. Most of them use a mixture of hydrogen and diesel or gasoline to achieve energy supply operations. This results in the water produced after the combustion of hydrogen being mixed with harmful substances produced by the combustion of diesel or gasoline. The water discharged by this hydrogen fuel engine is engine waste liquid, which needs to be treated before discharge to prevent impact on the environment.

[0003] The utility model patent with the authorization announcement number CN216974994U discloses a hydrogen fuel engine aftertreatment system and engine. The hydrogen fuel engine aftertreatment system includes an exhaust pipeline; a temperature sensor, which is located at the intake end of the exhaust pipeline; a first nitrogen oxide sensor, which is located at the intake end of the exhaust pipeline; a hydrogen injection device, which is connected to the exhaust pipeline and is located on the side of the intake end of the exhaust pipeline away from the temperature sensor; a hydrocarbon injection device, which is connected to the exhaust pipeline and is located on the side of the intake end of the exhaust pipeline away from the temperature sensor; a selective catalytic converter, which is connected to the outlet end of the exhaust pipeline; and a second nitrogen oxide sensor, which is located on the side of the selective catalytic converter away from the exhaust pipeline. The exhaust gas undergoes a hydrogen-assisted HC-SCR reaction inside the selective catalytic converter to achieve ultra-low NOx emissions.

[0004] Although the above utility model patent can process NOx in exhaust gas, it selects ordinary existing particulate matter collector to capture particulate matter. However, the particulate matter collector used in existing automobiles will use a filtering structure to filter and capture large and small particles of impurities at the same time during use, which is not convenient for removing large particles of impurities and is prone to blockage, resulting in large particles of impurities accumulating inside the particulate matter collector for a long time, affecting the gas discharge effect. Although it can avoid air pollution, it will increase vehicle fuel consumption and has defects. Summary of the invention

[0038] In this embodiment, in order to enable impurities on the surface of the rotating filter cartridge 31 to enter the collector 33 when the motor is started, and to prevent waste liquid from entering the collector 33 when the motor is turned off, a driving chamber is opened at the part of the partition plate 2 6 located at the top of the storage chamber, and an electromagnet 61 is arranged inside the driving chamber, and the electromagnet 61 is electrically connected to the circuit where the motor is located, and an iron block 62 is arranged on the right side of the electromagnet 61, and a closing plate 63 is fixed on the top of the iron block 62, and a slide groove is opened on the top of the partition plate 2 6, and the closing plate 63 is slidably installed inside the slide groove, and the right half of the closing plate 63 is located at the top of the right end of the storage chamber, and the left end of the closing plate 63 contacts with the top of the partition plate 2 6, the iron block 62 is slidably connected to the inside of the driving chamber, and a reset spring is arranged between the inner wall of the driving chamber and the iron block 62, and when the electromagnet 61 is energized to attract the iron block 62, the reset spring is in a compressed state.

[0039] In this embodiment, in order to react to the water passing through the rotating filter cartridge 31, thereby converting some toxic substances in the waste liquid into non-toxic substances and reducing the harm of the waste liquid to the environment, a reaction mechanism 8 is arranged inside the rotating filter cartridge 31, and the reaction mechanism 8 includes multiple reaction blocks 81 and a reaction strip 82. The reaction blocks 81 and the reaction strip 82 are alkaline substances. The sulfuric acid generated by the dissolution of sulfur dioxide in water can be neutralized into a neutral substance by reacting with the reaction blocks 81 and the reaction strip 82. One end of the reaction block 81 is fixed to the inner wall of the rotating filter cartridge 31, and the other end is close to the axis of the rotating filter cartridge 31. The reaction strip 82 contacts the top of the two reaction blocks 81 with the lowest height. A removal plate 83 is rotatably installed on the rear side of the reaction block 81. The front side of the removal plate 83 is fixed to the rear part of the reaction strip 82, and the removal plate 83 can be detachably installed on the rear side of the treatment equipment 1 through a snap-fit ​​part.

[0040] In this embodiment, in order to achieve the flow guiding effect of the reaction block 81 , both sides of the reaction block 81 are arc-shaped, and the concave arc side of one reaction block 81 is close to the convex arc side of the other reaction block 81 .

[0041] In this embodiment, a diversion mechanism 9 is provided at the left end of the partition plate 2 6 and the partition plate 3 7, and a diversion channel 71 is opened inside the partition plate 3 7. Two drainage ends 11 are fixed on the right side of the processing equipment 1, one drainage end 11 is connected to the right opening of the diversion channel 71, and the drainage end 11 directly discharges water to the external environment, and the other drainage end 11 is connected to the part between the bottom of the partition plate 3 7 and the bottom of the inner wall of the processing equipment 1, and the drainage end 11 discharges water to the area in the vehicle where water is needed, for example, adding water to a water storage tank for cleaning the vehicle windshield. In order to realize the diversion of the treated waste liquid and thus make full use of the treated waste liquid, the diversion mechanism 9 includes a floating block 91, a connecting rod 92 and a closed rotating plate 93. The floating block 91 is slidably installed on the left side of the inner wall of the processing equipment 1, one end of the connecting rod 92 is fixed to the top of the floating block 91, and the other end is connected to the top of the left end of the closed rotating plate 93, the right end of the closed rotating plate 93 is rotatably installed on the top of the partition plate 3 7, and the closed rotating plate 93 closes the left opening of the diversion channel 71.

[0042] In this embodiment, in order to balance the left and right movement of the connecting rod 92 when the closed rotating plate 93 is rotated by controlling the connecting rod 92, a fixed block 931 is fixed to the top of the left end of the closed rotating plate 93, and the fixed block 931 is slidably connected to one end of the connecting rod 92. The connecting rod 92 movably passes through the baffle 921, and the baffle 921 is fixed inside the processing equipment 1.

[0043] In the specific implementation process of this embodiment, its working principle is as follows: waste liquid is input from the top of the treatment device 1 into the inside of the treatment device 1, the waste liquid passes through the primary filtering mechanism 2, and part of the waste liquid is temporarily stored in the storage groove 211, and at the same time, part of the waste liquid will contact the guide baffle 213 when falling, and after being guided by the guide baffle 213, the waste liquid will not directly enter the Y-shaped water inlet groove 212, when the waste liquid in the storage groove 211 rises to the height of the top end point of the Y-shaped water inlet groove 212, the waste liquid in the storage groove 211 enters the Y-shaped water inlet groove 212 and flows downward through the particle capture layer 22, the particle capture layer 22 filters the waste liquid, and under the action of the narrow center of the storage groove 211, large particles of impurities will be blocked and stay in the storage groove 211, so that large particles can be crushed. The waste liquid is directly stored in the storage groove 211; when large debris accumulates, the water level in the storage groove 211 rises to the inclined plate 4 and exerts buoyancy on the water-passing floating plate 41. The water-passing floating plate 41 rotates and rises under the action of the buoyancy, thereby realizing the rise of the waste liquid. Under the inclined guiding action of both sides of the upper part of the storage groove 211, large impurities accumulate more at the bottom center of the storage groove 211. Therefore, large impurities accumulate in a cone shape at the bottom of the storage groove 211 to prevent large impurities from entering the Y-shaped water inlet trough 212. When large impurities accumulate at the bottom of the inclined plate 4 due to the shaking of the car, the large impurities cannot provide buoyancy to the water-passing floating plate 41, so the water-passing floating plate 41 cannot float up, so that the water-passing floating plate 41 will not rotate, and the large impurities will not pass through the inclined plate 4 and enter the Y-shaped water inlet trough 212.

[0044] The waste liquid that passes through the particle capture layer 22 will fall to the top of the partition plate 1 5, and then flow to the left under the guiding effect of the partition plate 1 5 and fall from the left end of the partition plate 1 5 to the top of the left end of the partition plate 2 6. The guiding effect of the partition plate 2 6 makes the waste liquid flow to the right, and in the process of flowing, the waste liquid will pass through the rotating filter cartridge 31, so as to be filtered twice, and the filtered impurities will adhere to the left surface of the rotating filter cartridge 31. When too many impurities adhere to the left side of the rotating filter cartridge 31, the driving device 32 is started, and the motor inside the driving device 32 is started and the output end of the motor drives the rotating filter cartridge 31 to rotate counterclockwise by 180 degrees. At this time, the right and left positions of the rotating filter cartridge 31 are swapped, and in the process of rotating the rotating filter cartridge 31, since the motor is energized, the electromagnet 61 When the motor is powered on, the electromagnet 61 attracts the iron block 62, and the iron block 62 drives the closing plate 63 to move left and compress the reset spring. At this time, the closing plate 63 is separated from the top of the right end of the collector 33. When the rotating filter cartridge 31 rotates, the left side of the contact part between the partition plate 2 6 and the rotating filter cartridge 31 will scrape the surface of the rotating filter cartridge 31, so that the impurities on the surface of the rotating filter cartridge 31 are scraped off and accumulated on the left side of the rotating filter cartridge 31. The scraped impurities enter the collector 33 for storage under the action of gravity. When the motor is powered off, the electromagnet 61 is also powered off. The iron block 62 and the closing plate 63 are reset under the action of the reset spring, and the closing plate 63 again blocks the top of the right end of the collector 33 to prevent waste liquid from entering the collector 33 and occupying storage space.

[0045] The waste liquid entering the rotating filter cartridge 31 will contact the reaction block 81, thereby achieving a reaction and diversion effect. The waste liquid guided through the gap between the two reaction blocks 81 will flow to the reaction strip 82 and contact the reaction strip 82, thereby achieving further reaction, reacting some harmful acidic substances in the waste liquid into neutral substances, preventing the discharged waste liquid from being acidic and affecting the environment, and the reaction strip 82 blocks the gap between the two reaction blocks 81 at the bottom, thereby preventing the waste liquid from directly passing through the rotating filter cartridge 31 after passing through the reaction strip 82, so as to increase the retention time of the waste liquid in the rotating filter cartridge 31, increase the reaction time of the waste liquid, and at the same time, the waste liquid impacts the reaction strip 82, a certain sputtering effect will be generated, thereby causing the waste liquid to spread, increasing the reaction area between the waste liquid and the reaction block 81 and the reaction strip 82, and thus improving the reaction effect; and in the drawings of the specification of the present application, the number and position of the rotating filter cartridge 31 and the reaction mechanism 8 are only schematic diagrams. In the specific implementation process, different numbers of rotating filter cartridges 31 and reaction mechanisms 8 can be assembled according to different engines to ensure the reaction effect. When the reaction mechanism 8 needs to be replaced, the removal plate 83 is directly removed from the rear side of the processing equipment 1 and the reaction block 81 and the reaction strip 82 are directly pulled out, and a new reaction mechanism 8 is inserted, so that the reaction mechanism 8 can be replaced;

[0046] The liquid flowing through the partition plate 3 7 moves to the left and then flows to the right from the bottom of the inner wall of the processing equipment 1 to the inside of a drainage end 11, and then flows into the water tank. The car can spray the water onto the windshield to clean the windshield, thereby improving energy utilization. After the water in the water tank is full, the liquid cannot continue to enter the water tank, so that the liquid level at the bottom of the processing equipment 1 continues to rise. As the liquid level rises, the buoyancy of the float 91 continues to increase and rises. During the rising process of the float 91, one end of the connecting rod 92 is driven to rise, and the other end of the connecting rod 92 pulls the closed rotating plate 93 to rotate through the fixed block 931. At this time, the closed rotating plate 93 opens the left end of the diversion channel 71, and the liquid at the bottom of the processing equipment 1 can enter the diversion channel 71 and be discharged through the drainage end 11, thereby preventing excessive accumulation of liquid.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
