When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0039] like Figures 1 to 12 As shown, a diesel generator exhaust gas treatment device of the present invention includes: an air inlet 1, an exhaust gas treatment unit 2 for filtering exhaust gas, a collection box 3 for collecting and discharging particles generated during treatment, and a dosing unit 4 for adjusting the agent according to the exhaust gas treatment amount; a dust removal port 31 is provided on the collection box 3.

[0040] The waste gas enters the waste gas treatment unit 2 through the air inlet 1. After being treated by the waste gas treatment unit 2, the particles fall into the collecting box 3. The waste gas enters the dosing unit 4. The dosing amount of the dosing unit 4 is adjusted according to the amount of waste gas entering. Finally, the waste gas and the liquid medicine are sprayed out synchronously to treat the harmful substances in the waste gas, thereby realizing dual treatment of the particles and harmful substances in the waste gas, and the treatment effect is good.

[0041] The exhaust gas treatment unit 2 includes: a wet treatment box 21 for treating harmful substances in the exhaust gas, and a dry filter box 22 fixedly installed on the wet treatment box 21 for treating particulate matter in the exhaust gas. The air inlet 1 is connected to any one of the multiple groups of dry filter boxes 22.

[0042] The dry filter box 22 includes: a rotating shaft 221 , an arc-shaped brush 2211 fixedly connected to the rotating shaft 221 , a primary filter 223 for filtering the exhaust gas, and a rear filter 224 , wherein the rear filter 224 is fixedly mounted on the dry filter box 22 .

[0043] When in use, the exhaust gas enters the dry filter box 22 through the air inlet 1, and is then discharged after being filtered by the primary filter 223 on the dry filter box 22, and then is discharged to the dosing unit 4 through the post filter 224. The primary filter 223 serves as a filter for initially filtering the exhaust gas, and its surface is easily clogged by particles, resulting in a decrease in the filtering effect. Therefore, a knocking component 222 for cleaning the primary filter 223 is provided.

[0044] The knocking assembly 222 includes: a cam 2221 fixedly mounted on the rotating shaft 221, a fixed shaft 2222 fixedly mounted on the cam 2221, a knocking hammer 2223 rotatably connected to the fixed shaft 2222, a push rod 2224 fixedly connected to the fixed shaft 2222, a spiral plate 2225 slidably mounted on the rotating shaft 221, and a limiting frame 2226 for limiting the knocking hammer 2223 during movement; the limiting frame 2226 is fixedly mounted on a side of the dry filter box 22 where the primary filter screen 223 is provided, and the limiting frame 2226 is in shape consistent with the hammer head of the knocking hammer 2223, and can limit the movement of the knocking hammer 2223 to prevent the knocking hammer 2223 from rotating under the action of the fixed shaft 2222. The limiting frame 2226 is preferably a cylindrical structure that matches the knocking hammer 2223, and can fully limit the movement of the knocking hammer 2223.

[0045] When in use, the power source drives the rotating shaft 221 to rotate, and the cam 2221 drives the striking hammer 2223 to impact toward the primary filter 223 under the limit of the limit frame 2226, so that the particles on the surface of the primary filter 223 fall off under continuous impact, thereby achieving the effect of cleaning the filter. When the exhaust gas is discharged through the rear filter 224, the rear filter 224 will perform a secondary filtering on the exhaust gas to improve the filtering effect of the exhaust gas. However, the rear filter 224 may still be blocked by the particles in the exhaust gas, resulting in smoke exhaust failure. Therefore, two groups of arc brushes 2211 are provided, and the collection box 3 and the rear filter 224 are cleaned respectively.

[0046] Specifically, when the rotating shaft 221 rotates, it drives the knocking hammer 2223 to clean the primary filter 223, and also drives the arc brush 2211 to rotate. When the arc brush 2211 cleans the rear filter 224, particles fall downward and may fall to the connection between the knocking hammer 2223 and the fixed shaft 2222, causing the rotation of the knocking hammer 2223 and the fixed shaft 2222 to fail, affecting the cleaning of the primary filter 223 and further affecting the use of the device. Therefore, a spiral plate 2225 is also provided on the rotating shaft 221. When the rear filter 224 is cleaned, the particles falling are blocked by the spiral plate 2225. Since the spiral plate 2225 is slidably connected to the rotating shaft 221, one end of the push rod 2224 abuts against the lower surface of the spiral plate 2225. The spiral setting of the spiral plate 2225 enables the push rod 2224 to move when the cam 2221 rotates. The spiral plate 2225 moves on the surface of the spiral plate 2225 and under the guidance of the lower spiral surface, the spiral plate 2225 moves upward along the axial direction of the rotating shaft 221, and when the push rod 2224 moves to one end of the spiral plate 2225 in the rotating direction, it disengages from the spiral plate 2225, causing the spiral plate 2225 to fall, generating vibration, and shaking off the particles on the upper surface of the spiral plate 2225. Then the cam 2221 continues to rotate, and the push rod 2224 pushes the spiral plate 2225 upward again, causing the spiral plate 2225 to move back and forth. The push rod 2224 pushes the spiral plate 2225 to move up on the surface of the rotating shaft 221 and then falls, causing the particles on the spiral plate 2225 to fall into the inside of the collecting box 3. When the rotating shaft 221 rotates, it drives the arc brush 2211 to rotate, and the particles inside the collecting box 3 are discharged through the dust removal port 31, completing the preliminary particulate matter treatment of the exhaust gas.

[0047] In summary, while the rotating shaft 221 is rotating, on the one hand, it can drive the knocking component 222 to hit the primary filter 223 to clean the particles on the surface of the primary filter 223, and while rotating, it can push the spiral plate 2225 to move through the push rod 2224 to facilitate the collection and treatment of the particles. On the other hand, the arc brush 2211 can collect and treat the particles inside the rear filter 224 and the collection box 3, which has a good treatment effect on the exhaust gas and can also reduce the maintenance cost of the primary filter 223 and the rear filter 224.

[0048] As a further extension of the present application, the primary filter 223 is composed of a front plate 2231 fixedly mounted on the dry filter box 22, a filter hole 22311 opened on the front plate 2231, an elastic member 2233 fixedly mounted on the front plate 2231, a rear plate 2232 fixedly mounted on the elastic member 2233, and a filter hole 22321 opened on the rear plate 2232; a cleaning brush 22312 is fixedly connected to the front plate 2231, and the cleaning brush 22312 is connected to the filter hole 223 21 positions correspond one to one. When the striking hammer 2223 hits the primary filter screen 223, it first collides with the rear plate 2232, and causes the elastic member 1 2233 to deform under force. At the same time, the cleaning brush enters the interior of the filter hole 22321 to push out the particles blocked in the filter hole 22321 to complete the cleaning. The elastic member 1 2233 can not only drive the rear plate 2232 to reset after being hit, but also increase the vibration of the rear plate 2232, thereby having a better cleaning effect on the particles on the rear plate 2232.

[0049] It should be noted that the size of the filter hole 1 22311 only needs to ensure that the exhaust gas can be discharged through the front plate 2231. To avoid clogging, the size of the filter hole 1 22311 can be larger than the size of the particles in the exhaust gas.

[0050] In addition, taking into account the actual usage situation, the blockage of the primary filter 223 will not occur directly, and the primary filter 223 does not need to be continuously cleaned. It is necessary to ensure that when the primary filter 223 is cleaned, the device can still be used normally to filter the exhaust gas. Therefore, four groups of dry filter boxes 22 are provided, and the four groups of dry filter boxes 22 are connected in sequence through pipes. The four groups of dry filters are adjacent, and each group of dry filter boxes 22 is provided with a primary filter 223, and the position of the primary filter 223 increases from bottom to top, and the number and knocking direction of the knocking components 222 correspond to the primary filter 223.

[0051] The waste gas enters multiple groups of dry filter boxes 22 for processing. When the primary filter 223 needs to be cleaned, the rotating shaft 221 drives multiple groups of knocking components 222 to clean the primary filter 223 on the multiple groups of dry filter boxes 22 in turn, ensuring that the knocking components 222 and the rear plate 2232 collide with each other in turn, ensuring that at least one group of cleaning brushes 22312 on the dry filter box 22 does not enter the filter hole 22321, avoiding the knocking component 222 from colliding with the rear plate 2232, causing the cleaning brush 22312 to block the filter hole 22321, resulting in the device being unable to process the waste gas.

[0052] On the one hand, the exhaust gas usually has a certain temperature. When the exhaust gas is subjected to particle filtering, the temperature of the exhaust gas may reduce the service life of the primary filter 223. On the other hand, in order to ensure the neutralization of harmful substances in the exhaust gas, it is necessary to add an appropriate amount of liquid medicine to the water liquid. Therefore, the present application sets a dosing unit 4 to perform secondary treatment on the exhaust gas. Through the dosing unit 4, firstly, there is water liquid inside the wet treatment box 21 to treat the exhaust gas, and the filtering effect of the exhaust gas is good. Secondly, when the exhaust gas inside the wet treatment box 21 is treated, the internal temperature of the wet treatment box 21 is lower under the action of the water liquid, and the wet treatment box 21 is located outside the four groups of dry filter boxes 22. The temperature inside the dry filter box 22 can be reduced through heat transfer, thereby reducing the temperature of the exhaust gas and avoiding the exhaust gas temperature from damaging the primary filter 223.

[0053] The dosing unit 4 includes: an air pipe 41, a bag 43 for collecting waste gas, a partition plate 42 for supporting the bag 43, a medicine box 44 for adjusting the spraying amount according to the amount of waste gas collected by the bag 43, and a medicine outlet pipe 45 connected to the medicine box 44; the air pipe 41 is connected to the rear filter 224.

[0054] An air outlet 212 is provided on the wet treatment box 21, and a water filter 211 is fixedly installed on the wet treatment box 21; after the exhaust gas is discharged through the rear filter 224, the exhaust gas is discharged to the inside of the wet treatment box through the capsule 43, and at the same time, water is sprayed into the wet treatment box through an external water spraying device to neutralize the liquid medicine in the water with the harmful substances in the exhaust gas, thereby reducing the harm of the exhaust gas emission to the environment. After the water is filtered through the water filter 211, it is centrally treated, and the exhaust gas is discharged to the outside through the air outlet 212.

[0055] The waste gas enters the interior of the capsule 43 through the air pipe 41, and the amount of medicine to be added to the water liquid is adjusted according to the amount of waste gas inside the capsule 43, and is discharged through the medicine outlet pipe 45. Specifically, a reset member 431 is fixedly connected to the inner wall of the capsule 43, a positioning groove 421 is provided on the partition plate 42, and a limiting groove 4211 that cooperates with the limiting block 413 is provided on the positioning groove 421. A connecting hole 441 is provided at the connection between the medicine box 44 and the capsule 43, a pushing plate 442 is slidably connected to the inner wall of the medicine box 44, and a reset member 443 is fixedly connected to the pushing plate 442; the reset member 443 is fixedly connected to the medicine box 44.

[0056] It should be emphasized here that after the exhaust gas enters the interior of the capsule 43, it will cause the capsule 43 to expand and increase its volume. The present application reduces the damage to the capsule 43 caused by the exhaust gas due to temperature by lowering the temperature of the exhaust gas, and at the same time can indicate the amount of medicine added to the water, which is easy to use.

[0057] When in use, when waste gas continues to enter the capsule 43 , the waste gas enters the medicine box 44 through the connecting hole 441 , so that the air pressure in the medicine box 44 increases, thereby pushing the push plate 442 to move inside the medicine box 44 and pushing the medicine liquid inside the medicine box 44 out through the medicine outlet pipe 45 .

[0058] It is important to note that please refer to Fig. 9 When the push plate 442 continues to move along the axial direction of the medicine box 44, when the push plate 442 moves to above the connection between the medicine outlet pipe 45 and the medicine box 44, the waste gas of the medicine box 44 is discharged through the medicine outlet pipe 45, causing pressure relief, breaking the dynamic pressure balance between the medicine box 44 and the capsule 43, the push plate 442 is reset under the action of the reset member 443, and the capsule 43 is reset under the action of the reset member 431.

[0059] In order to ensure that the exhaust gas can be continuously treated, the present application is provided with a plurality of capsules 43, a reversing sleeve 411 is slidably connected to the air pipe 41, an air outlet 412 is opened on the reversing sleeve 411, a limited block 413 is fixedly connected to the reversing sleeve 411, an elastic member 414 is fixedly connected to the reversing sleeve 411, and an exhaust gas reversing pipe 415 connecting the capsule 43 and the reversing sleeve 411 is fixedly installed on the partition plate 42, and the limiting groove 4211 is composed of an oblique groove and a straight groove, and the exhaust gas enters the capsule 43 through the air outlet 412 on the reversing sleeve 411 When the exhaust gas can no longer enter the sac 43, the continuous delivery of exhaust gas will push the reversing sleeve 411 to slide in the positioning groove 421, and at the same time, the limit block 413 will rotate under the guidance of the inclined groove, so that the reversing sleeve 411 will supply air to another group of exhaust gas exchange tubes 415 through the air outlet 412. When the air outlet 412 supplies air to another group of exhaust gas exchange tubes 415, the pressure in the air pipe 41 will be reduced. At this time, the elastic member 414 will be reset, driving the reversing sleeve 411 to slide and reset in the straight groove through the limit block 413, so as to facilitate the next use.

[0060] To ensure the use effect, the reset member 1 431, the reset member 2 443, the elastic member 1 2233, and the elastic member 2 414 in the present application are preferably springs.

[0061] Through the above structure, the device can, on the one hand, transfer the exhaust gas quantitatively and add an appropriate amount of liquid medicine to neutralize the harmful substances in the exhaust gas. On the other hand, by setting up multiple groups of capsules 43 and reversing sleeves 411, the device can continuously treat the exhaust gas with good treatment effect.

[0062] The present application processes the waste gas into particles and then sends it into the capsule 43, restricts the processing volume of the waste gas through the capsule 43, and quantitatively delivers appropriate liquid medicine according to the processing volume of the waste gas. While wet-treating the waste gas and neutralizing harmful substances in the waste gas, the temperature of the water liquid is used to cool the dry filter box 22 to reduce the temperature of the waste gas, thereby preventing the waste gas from affecting the use of parts such as the primary filter 223 and the capsule 43.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
