Description

Technical Field

[0001] This invention relates to the field of diesel engine exhaust purification technology, specifically a diesel engine exhaust water washing and purification device. Background Technology

[0002] Diesel engine exhaust gas is the collective term for the gaseous, liquid, and solid mixture emitted from the exhaust pipe during the combustion of diesel fuel to generate power in a diesel engine. As a significant type of internal combustion engine emission, it is complex in composition and contains various pollutants. Widely present in power applications such as ships, construction machinery, heavy trucks, and stationary generator sets, it has a significant impact on the environment and human health, and is a key target for current air pollution control. Diesel engine exhaust gas water washing and purification equipment is an environmentally friendly device based on the principle of "water absorption" to purify diesel engine exhaust gas. Its core function is to remove some pollutants from the exhaust gas through sufficient contact between water and exhaust gas, thereby reducing exhaust gas pollution to the atmospheric environment. It is widely used in exhaust gas treatment scenarios for non-road and road mobile sources such as ships, construction machinery, stationary generator sets, and diesel trucks.

[0003] In the water washing and purification of diesel engine exhaust, spraying the exhaust gas is a commonly used treatment method; however, the wastewater generated after spraying needs to be filtered. In the wastewater filtration process, the impurities it carries can easily cause the screen to become clogged when it flows through the screen. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solution: a diesel engine exhaust gas water washing and purification device, comprising:

[0007] The filtering component includes a filter plate one and a filter plate two. The sides of both filter plate one and filter plate two are fixedly connected to the inner side of the main body. A staged filtration mode using filter plate one and filter plate two is employed, first intercepting large particles of impurities, then retaining fine impurities. A collection box is fixedly connected to the middle of the inner side of filter plate one. The collection box centrally collects large particles of impurities, preventing them from being dispersed inside the equipment and difficult to clean. The side of the collection box is fixedly connected to the inner side of filter plate two. A rotating shaft is rotatably connected to the middle of the inner cavity of the collection box. The top of the guide plate is connected to... The bottom of the rotating shaft is fixedly connected, and rotating rods one are evenly arranged on the side of the rotating shaft.

Rotating rods two are evenly arranged on the side of the rotating shaft away from rotating rod one. The side of rotating rod two is fixedly connected to the inner side of the rotating shaft, and the bottom of rotating rod two is rotatably connected to the bottom of the inner cavity of the collection box. Rotating rod two stirs up impurities in the collection box, causing residual washing water to flow out and be recycled through the mesh, further reducing water waste.

[0008] Preferably, the mixing component includes a mixing shell, the top of which is fixedly connected to the bottom of the main body. Mesh plates are fixedly connected to both the upper and lower sides of the mixing shell. A spiral blade is rotatably connected to the middle of the two mesh plates. The top of the spiral blade is fixedly connected to the bottom of a rotating shaft. Extrusion rods are slidably connected to both sides of the mixing shell. An extrusion block is fixedly connected to one end of each extrusion rod, and an extrusion frame is fixedly connected to the other end. The side of the extrusion frame is slidably connected to the inner side of the mixing shell. Material stops are fixedly connected to both the upper and lower sides of the extrusion frame. The block has a side that is slidably connected to the inside of the mixing shell. The side of the block has evenly spaced circular grooves. The block carries out the medicine through the circular grooves of a fixed volume, which can control the amount of medicine added each time and avoid the problem of over- or under-dosing in traditional manual dosing. The extrusion rod is fitted with a first spring. The reset function of the first spring ensures that the extrusion block and the block can work repeatedly, and the medicine can be continuously added without manual intervention. One end of the first spring is fixedly connected to the side of the extrusion frame, and the other end of the first spring is fixedly connected to the inside of the mixing shell.

[0009] Preferably, the storage component includes a storage shell, the top of which is fixedly connected to the bottom of the mixing shell, a water pump is fixedly connected to the bottom of the inner cavity of the storage shell, the output end of the water pump is fixedly connected to the end of the connecting pipe away from the spray frame, an intercepting net is fixedly connected to the middle of the inner side of the storage shell, return pipes are fixedly connected to both sides of the storage shell, a collection cylinder is installed between the two return pipes, the two return pipes are located above the intercepting net, the two return pipes are located below the intercepting net, a one-way valve is provided on the side of the two lower return pipes near the storage shell, and a cleaning mechanism is rotatably connected to the top of the intercepting net, the stirring action of the cleaning mechanism accelerates the flocculation reaction of the agent and impurities;

[0010] Preferably, the cleaning mechanism includes a cleaning rod, the top of which is fixedly connected to the bottom of the spiral blade, the bottom of which is rotatably connected to the top of the intercepting mesh plate, cleaning shafts are evenly arranged on the side of the cleaning rod, the side of which is fixedly connected to the inner side of the cleaning rod, a connecting block is fixedly connected to the other end of the cleaning shaft, and a contact component is fixedly connected to the side of the connecting block away from the cleaning shaft.

[0011] Preferably, the contact assembly includes a slide rod, one end of which is fixedly connected to a contact plate, the side of which is slidably connected to the inside of a connecting block, the end of the slide rod away from the contact plate being slidably connected to the inside of the connecting block, and a second spring being sleeved on the slide rod, one end of which is fixedly connected to the inside of the connecting block, and the other end of which is fixedly connected to the side of the contact plate.

[0012] This invention provides a diesel engine exhaust gas water washing and purification device. It has the following beneficial effects:

[0013] 1. This diesel engine exhaust water washing and purification equipment is equipped with a filter component. Traditional filter plates are prone to pore blockage due to impurity accumulation, requiring frequent shutdowns for cleaning and affecting continuous operation. In this process, the rotating rod actively scrapes and guides the filter plate to remove impurities from its surface in real time, preventing impurities from clogging the pores and ensuring that the filter plate maintains high permeability without frequent shutdowns for maintenance.

[0014] 2. This diesel engine exhaust gas washing and purification equipment is equipped with a mixing component. The rotation of the spiral blade and the carry-out of the agent both rely on the exhaust gas impact power of the guide plate, without the need for additional drive components. The baffle block carries out the agent through a circular groove with a fixed volume, which can control the amount of agent added each time, avoiding the problem of over- or under-dosing in traditional manual dosing. On the one hand, it reduces agent waste, and on the other hand, it prevents secondary pollution of the washing water caused by excessive agent residue.

[0015] 3. This diesel engine exhaust water washing and purification equipment is equipped with a storage component. The collection cylinder adopts a detachable design with fastener connection. No special tools are required for cleaning. A single person can complete the entire process of disassembly, cleaning and reassembly. Compared with traditional shell disassembly cleaning, the operation and maintenance difficulty is greatly reduced, and the risk of component damage caused by complex maintenance is reduced.

[0016] 4. This diesel engine exhaust water washing and purification equipment is equipped with a contact component. When the cleaning bar speed changes, the spring force can dynamically balance with the centrifugal force, ensuring that the contact plate always adheres to the inner wall of the outer shell with appropriate pressure. Even if there are slight irregularities in the inner wall of the outer shell, it can be adaptively adjusted by the extension and contraction of the spring to avoid cleaning dead corners.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1, please refer to Figures 1-3 This invention provides a technical solution: a diesel engine exhaust gas water washing and purification device, comprising:

[0028] The main body 1 has a flame arrester 2 fixedly connected to its side, an air outlet pipe 6 fixedly connected to its top, a fiber demister 7 fixedly connected to the top of the inner cavity of the main body 1, a packing 9 fixedly connected to the middle of the inner side of the main body 1, a mixing component 3 fixedly connected to the bottom of the main body 1, a storage component 4 fixedly connected to the bottom of the mixing component 3, a connecting pipe 5 fixedly connected to the side of the storage component 4, and a spray frame 8 fixedly connected to the other end of the connecting pipe 5.

[0029] The filter component 10 is used to filter the wastewater after the exhaust gas is washed. The side of the filter component 10 is fixedly connected to the inside of the main body 1. The bottom of the filter component 10 is rotatably connected to the guide plate 11, which is flush with the flame arrester 2.

[0030] Please see Figure 4The filter component 10 includes a first filter plate 101 and a second filter plate 103. The sides of both the first filter plate 101 and the second filter plate 103 are fixedly connected to the inner side of the main body 1. A collection box 102 is fixedly connected to the middle of the inner side of the first filter plate 101. The side of the collection box 102 is fixedly connected to the inner side of the second filter plate 103. A rotating shaft 106 is rotatably connected to the middle of the inner cavity of the collection box 102. The top of the guide plate 11 is fixedly connected to the bottom of the rotating shaft 106. A first rotating rod 104 is evenly arranged on the side of the rotating shaft 106. The side of the first rotating rod 104 is fixedly connected to the inner side of the rotating shaft 106. The bottom of the first rotating rod 104 is rotatably connected to the top of the first filter plate 101. A second rotating rod 105 is evenly arranged on the side of the rotating shaft 106 away from the first rotating rod 104. The side of the second rotating rod 105 is fixedly connected to the inner side of the rotating shaft 106. The bottom of the second rotating rod 105 is rotatably connected to the bottom of the inner cavity of the collection box 102.

[0031] The washing water containing mixed impurities first flows through filter plate 101. Filter plate 101 performs preliminary filtration of the wastewater through its own pores, directly intercepting larger particulate impurities in the water.

[0032] At the same time, when the diesel exhaust gas enters the main body 1, it will continuously impact the guide plate 11 adapted to the exhaust gas passage. It is horizontally aligned with the flame arrester 2 to ensure stable exhaust gas impact force and drive the guide plate 11 to rotate inside the main body 1. The guide plate 11 is rigidly connected to the rotating shaft 106, thereby driving the rotating shaft 106 to rotate synchronously. The rotating rod 104 at the top of the rotating shaft 106 is designed to be curved and rotates with the shaft, making circumferential motion on the top surface of the filter plate 101.

[0033] Due to the arc-shaped structure of the rotating rod 104, a centripetal guiding force is generated when it rotates, which gradually gathers the large particles of impurities intercepted on the surface of the filter plate 101 toward the center of the plate, and finally scrapes the impurities into the collection box 102 located below the center of the filter plate 101, thus completing the centralized collection of impurities.

[0034] The washing water that has undergone preliminary filtration by filter plate 101 continues to flow downwards and enters filter plate 103 for secondary filtration, further trapping fine particulate impurities remaining in the water and improving the cleanliness of the washing water.

[0035] While the rotating shaft 106 rotates, the rotating rod 105 connected to its bottom rotates synchronously inside the collection box 102, stirring the impurities accumulated at the bottom of the inner cavity of the collection box 102, so that some of the washing water that enters the collection box 102 with the impurities can flow down through the mesh opening at the bottom of the collection box 102 and flow into the clean water treated by the filter plate 103, thereby maximizing the recovery of washing water.

[0036] Example 2, please refer to Figure 5Based on Embodiment 1, the present invention provides a technical solution: the mixing component 3 includes a mixing shell 31, the top of the mixing shell 31 is fixedly connected to the bottom of the main body 1, mesh plates 32 are fixedly connected to both the upper and lower sides of the mixing shell 31, a spiral blade 33 is rotatably connected to the middle of the two mesh plates 32, the top of the spiral blade 33 is fixedly connected to the bottom of the rotating shaft 106, an extrusion rod 34 is slidably connected to both sides of the mixing shell 31, an extrusion block 35 is fixedly connected to one end of the extrusion rod 34, an extrusion frame 36 is fixedly connected to the other end of the extrusion rod 34, the side of the extrusion frame 36 is slidably connected to the inner side of the mixing shell 31, a baffle block 38 is fixedly connected to both the upper and lower sides of the extrusion frame 36, the side of the baffle block 38 is slidably connected to the inner side of the mixing shell 31, a circular groove is evenly opened on the side of the baffle block 38, a first spring 37 is sleeved on the extrusion rod 34, one end of the first spring 37 is fixedly connected to the side of the extrusion frame 36, and the other end of the first spring 37 is fixedly connected to the inner side of the mixing shell 31;

[0037] The washing water after being treated by filter plate 101 and filter plate 103 has removed most of the solid particles, but still has fine impurities that need to be separated by sedimentation.

[0038] When the guide plate 11 rotates continuously under the impact of exhaust gas, it will synchronously drive the spiral blade 33 to rotate between the two mesh plates 32 inside the mixing shell 31. As the spiral blade 33 rotates, its blades will come into contact with the extrusion block 35 in the inner cavity of the mixing shell 31 and generate extrusion force. After the extrusion block 35 is subjected to force, it will push the extrusion rod 34 connected to it and compress the first spring 37 sleeved on the extrusion rod 34, causing the extrusion rod 34 to move towards the inside of the mixing shell 31.

[0039] When the extrusion rod 34 moves, it will drive the baffle block 38 inside the mixing shell 31 to move synchronously through the extrusion frame 36. Since the surface of the baffle block 38 is uniformly provided with circular grooves, during the movement of the baffle block 38, the circular grooves on its side will carry the precipitated agent stored in the mixing shell 31, and carry the agent out to the washing water channel of the mixing shell 31 as the baffle block 38 moves.

[0040] The wash water, after undergoing two stages of filtration, flows continuously downwards along the side channel of the mixing shell 31, directly contacting the precipitated chemicals carried out by the circular groove of the baffle block 38. The scouring force of the water flow combined with the diffusion effect of the chemicals ensures that the chemicals are evenly integrated into the wash water, forming a mixture of chemicals and wash water.

[0041] When the spiral blade 33 rotates to the position where it is disengaged from the extrusion block 35, the compressed first spring 37 will release its elastic force, pushing the extrusion rod 34, the extrusion frame 36 and the baffle block 38 back to their initial positions; then the spiral blade 33 continues to rotate, and will contact the extrusion block 35 again and repeat the extrusion process, thereby realizing the intermittent and continuous addition of the precipitation agent, ensuring that each section of water flow can be fully mixed with the agent;

[0042] Example 2, please refer to Figure 6 Based on Embodiment 1, the present invention provides a technical solution: the storage component 4 includes a storage shell 41, the top of the storage shell 41 is fixedly connected to the bottom of the mixing shell 31, a water pump 42 is fixedly connected to the bottom of the inner cavity of the storage shell 41, the output end of the water pump 42 is fixedly connected to the end of the connecting pipe 5 away from the spray frame 8, an interception net 43 is fixedly connected to the middle of the inner side of the storage shell 41, a return pipe 44 is fixedly connected to both sides of the storage shell 41, a collection cylinder 45 is installed between the two return pipes 44, the two return pipes 44 are located above the interception net 43, the two return pipes 44 are located below the interception net 43, a one-way valve is provided on the side of the two lower return pipes 44 near the storage shell 41, and a cleaning mechanism 46 is rotatably connected to the top of the interception net 43;

[0043] The washing water mixed with the chemicals will flow continuously downward through the mesh plate 32 and enter the storage shell 41 of the equipment;

[0044] At the same time, when the guide plate 11 rotates under the impact of the exhaust gas, it will drive the spiral blade 33 in sync, which in turn drives the cleaning mechanism 46 to rotate on the surface of the interception net 43 inside the storage shell 41. The rotation of the cleaning mechanism 46 can not only fully agitate the mixed agent inside the storage shell 41 and break the water flow stratification, but also accelerate the contact reaction between fine impurities and the agent, promote the impurities to quickly form larger flocs, and greatly shorten the time required for settling.

[0045] When impurities in the washing water form flocs, they are blocked above the screen by the interception net 43, while the clean washing water that has removed the impurities can pass through the holes of the interception net 43 and continue to flow downwards, eventually being stored at the bottom of the inner cavity of the storage shell 41 as the water source for subsequent circulating spraying.

[0046] When the cleaning mechanism 46 rotates on the surface of the interception net 43, it will simultaneously push the flocculated impurities remaining on the net surface toward the return pipe 44 on the side wall of the storage shell 41. During the pushing process, a small amount of washing water carried with the impurities will enter the return pipe 44 together with the impurities and flow into the collection cylinder 45 through the return pipe 44. The inner side of the collection cylinder 45 is provided with a baffle that can intercept the flocculated impurities that enter with the water flow, while the small amount of washing water carried can pass through the baffle and flow back to the storage shell 41 through the return pipe 44 connected to the bottom of the collection cylinder 45, thereby realizing water resource recycling.

[0047] When impurities accumulate to a certain amount inside the collection cylinder 45, simply remove the fasteners connecting the collection cylinder 45 to the upper and lower return pipes 44 to remove the entire collection cylinder 45 and clean the impurities trapped inside; after cleaning, reinstall and tighten the fasteners to restore its use.

[0048] When the equipment needs to continue to perform exhaust gas washing and purification, the water pump 42 at the bottom of the inner cavity of the storage shell 41 is turned on. The water pump 42 continuously delivers the stored clean washing water to the spray frame 8 through the connecting pipe 5 at the output end, and reuses it for exhaust gas washing and purification.

[0049] Please see Figure 7 The cleaning mechanism 46 includes a cleaning rod 461, the top of which is fixedly connected to the bottom of the spiral blade 33, the bottom of which is rotatably connected to the top of the interception net plate 43, and cleaning shafts 462 are evenly arranged on the side of the cleaning rod 461. The side of the cleaning shafts 462 is fixedly connected to the inner side of the cleaning rod 461, and a connecting block 463 is fixedly connected to the other end of the cleaning shafts 462. A contact component 464 is fixedly connected to the side of the connecting block 463 away from the cleaning shafts 462.

[0050] When the guide vane 11 rotates due to the impact of exhaust gas, it will drive the spiral blade 33 to rotate synchronously; the spiral blade 33 further drives the cleaning rod 461 to rotate synchronously on the surface of the interception net 43 inside the storage shell 41.

[0051] On the one hand, when the sweeping rod 461 rotates, it will drive the sweeping shaft 462 and the connecting block 463 connected to its side to fully stir the washing water mixed with the agent. By stirring, the still state of the water flow is broken, the contact reaction between the agent and the fine impurities in the washing water is accelerated, and the impurities are made to form flocs and settle more quickly, thus shortening the sedimentation cycle.

[0052] On the other hand, as the cleaning shaft 462 rotates with the cleaning rod 461, it drives the contact component 464 connected to it to continuously contact and rotate relative to the inner wall of the storage shell 41. This contact and rotation process can scrape the inner wall of the storage shell 41 in real time, preventing impurities that have been flocculated and precipitated in the washing water from adhering to the shell wall and preventing scale buildup on the shell wall from affecting subsequent cleaning and equipment operation.

[0053] Please see Figure 8 The contact assembly 464 includes a slide rod 4641, one end of which is fixedly connected to a contact plate 4642. The side of the contact plate 4642 is slidably connected to the inner side of the connecting block 463. The end of the slide rod 4641 away from the contact plate 4642 is slidably connected to the inner side of the connecting block 463. A second spring 4643 is sleeved on the slide rod 4641. One end of the second spring 4643 is fixedly connected to the inner side of the connecting block 463, and the other end of the second spring 4643 is fixedly connected to the side of the contact plate 4642.

[0054] When the cleaning rod 461 rotates on the surface of the interception net 43, centrifugal force is generated due to the rotation. Under the action of centrifugal force, the contact plate 4642 overcomes the elastic force of the second spring 4643 sleeved on the slide rod 4641 and moves away from the inner side of the connecting block 463 through the slide rod 4641. Finally, the contact plate 4642 is in close contact with the inner wall of the storage shell 41. As the cleaning rod 461 continues to rotate, the contact plate 4642 will rotate synchronously along the inner wall of the storage shell 41 to clean the washing water flocculation and sediment impurities that may be attached to the inner wall of the storage shell 41 in real time, and avoid the accumulation of impurities on the shell wall.

[0055] Specific workflow:

[0056] Exhaust gas pretreatment and safety protection: The exhaust gas discharged from the diesel engine enters the main body 1 through the flame arrester 2. The flame arrester 2 filters out any sparks that may be carried in the exhaust gas, preventing subsequent ignition of water vapor in the main body 1 and ensuring the safe operation of the system.

[0057] Core steps in exhaust gas washing and purification:

[0058] First, turn on the storage component 4, which continuously delivers washing water to the spray frame 8 through the connecting pipe 5;

[0059] The washing water sprayed out by the spray frame 8 performs a preliminary water wash on the exhaust gas that has entered the main body of the equipment 1;

[0060] When the washing water flows through the packing material 9, it is dispersed into a thin film, droplets or fine streams on the surface of the packing material 9, which greatly increases the surface area of ​​the liquid phase. At the same time, when the exhaust gas passes through the gaps in the packing material 9 layer, it is divided into fine airflows by the packing material 9, which prolongs the contact time with the washing liquid, thereby fully removing pollutants.

[0061] Demisting and emission of purified exhaust gas: The exhaust gas after water washing and purification flows upward and passes through the fiber demister 7 with a wire mesh structure. The demister intercepts the liquid droplets carried in the exhaust gas and finally discharges it through the exhaust pipe 6.

[0062] Treatment and recycling of laundry wastewater:

[0063] The washing water undergoes purification first through the filter element 10 for filtration, and then continues to flow downwards.

[0064] At the same time, when the exhaust gas enters the main body 1 of the equipment, it will impact the guide plate 11 which is horizontally arranged with the flame arrester 2, causing the guide plate 11 to rotate inside the main body 1.

[0065] The rotating guide plate 11 further promotes the filtration wastewater flowing into the mixing component 3 to mix fully with the reagents in the mixing component 3, thereby enhancing the impurity treatment effect;

[0066] After mixing and secondary treatment, the wastewater continues to flow downwards and eventually enters storage component 4 for sedimentation and filtration, realizing wastewater recycling and preparing for subsequent recycling.
