[0002] With the acceleration of industrialization, diesel generator sets have been widely used in various fields as important backup power equipment. However, during the operation of diesel generators, a large amount of flue gas containing harmful substances such as particulate matter, nitrogen oxides, carbon monoxide, etc. will be generated. These flue gases directly discharged into the atmosphere will cause serious pollution to the environment and affect human health and ecological balance.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] This is the first embodiment of the present invention, which provides a smoke elimination device for a diesel generator set.

[0040] Specifically, refer to Figure 1 to Figure 7 , including a diesel generator set 100;

[0041] The smoke elimination assembly 200 includes a fixing frame 201, a smoke blowing cylinder 202 fixed inside the fixing frame 201, a smoke elimination cylinder 203 disposed at the end of the smoke blowing cylinder 202, and a first filter layer 204 disposed on the inner wall of the smoke elimination cylinder 203;

[0042] The cooling spray assembly 300 includes a water supply box 301 arranged on the outer wall of the fixing frame 201, a water supply pipe 302 arranged at the end of the water supply box 301, a spray pipe 303 fixed inside the smoke elimination tube 203 and a water collecting tube 304 fixed at the end of the smoke blowing tube 202.

[0043] The smoke elimination component 200 is connected to the diesel generator set 100. The smoke generated when the diesel generator set 100 is working and generating electricity enters the smoke elimination component 200, enters the smoke blowing tube 202, and then enters the upper smoke elimination tube 203 through the smoke blowing tube 202. The cooling spray component 300 is responsible for supplying water and cooling the smoke elimination component 200. The water supply pipe 302 is wrapped around the outside of the smoke blowing tube 202. While cooling the smoke blowing tube 202, water enters the smoke elimination tube 203 through the water supply pipe 302. In the spray pipe 303 inside the cylinder 203, water vapor is generated in the smoke elimination cylinder 203 through the spray pipe 303 to mix the smoke generated by the diesel generator set 100. Harmful substances such as soot, carbon monoxide, hydrocarbons, etc. in the smoke can be adsorbed and precipitated by the water vapor, thereby reducing the concentration of pollutants in the smoke. The water vapor in the spray pipe 303 first reduces the content of particulate matter such as soot and black smoke in the smoke, and the remaining substances in the smoke continue to pass upward through the first filter layer 204 for adsorption.

[0044] At the same time, the sewage mixed with water vapor and smoke flows downward, and finally enters the water collecting cylinder 304 at the bottom, and then is discharged to the outside and enters the sewage treatment step.

[0045] In summary, when in use, the black smoke generated by the diesel generator set 100 when in operation enters the smoke blowing tube 202, and then enters the upper smoke elimination tube 203 through the smoke blowing tube 202. The spray pipe 303 and the first filter layer 204 are installed inside the smoke elimination tube 203. When the diesel generator set 100 is running at a low power, less black smoke is generated at this time, the cooling spray assembly 300 does not operate, and the spray pipe 303 does not spray water vapor in the smoke elimination tube 203. At this time, the water vapor passes through the first filter layer 204. To adsorb pollutant particles inside the smoke, when the diesel generator set 100 is running at high power, the water supply tank 301 transports water to the water supply pipe 302. The water supply pipe 302 cools down the chimney 202 while spraying water vapor through the spray pipe 303 to adsorb and precipitate pollutants in the smoke, adsorbing part of the soot and other substances in the smoke, reducing the concentration of pollutants in the smoke, and the water vapor finally gathers inside the water collecting tube 304 and is discharged from the chimney 202 to enter the next step of sewage treatment.

[0046] Example 2

[0047] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0048] Specifically, refer to Figure 3 A smoke inlet pipe 2021 is arranged on the outer wall of the smoke blowing tube 202 and the other end of the smoke inlet pipe 2021 is connected to the diesel generator set 100 . A guide plate 2022 is also arranged in an array on the inner wall of the smoke blowing tube 202 .

[0049] Among them, the smoke blowing tube 202 is fixed inside the fixing frame 201. When the diesel generator set 100 is running, the smoke enters the smoke blowing tube 202 through the smoke inlet pipe 2021. The guide plates 2022 in the array inside the smoke blowing tube 202 will guide the smoke, so that the smoke rotates upward in a swirling manner inside the smoke blowing tube 202, thereby accelerating the movement speed of the smoke.

[0050] Preferably, refer to Figure 3~Figure 5 A landslide 2031 is provided at the end of the smoke elimination tube 203, a baffle 2032 is provided at the end of the landslide 2031 and the baffle 2032 is located at the end of the smoke blowing tube 202, a curved groove 2033 is provided in an end face array of the baffle 2032, an arc groove 2034 is provided on the inner wall of the baffle 2032, a disc 2035 is provided on the inner wall of the baffle 2032 and a flap 2036 is hinged on the outer wall of the disc 2035, a sliding column 2037 is provided on the outer wall of the flap 2036 and the end of the sliding column 2037 extends to the inner wall of the arc groove 2034 and slides with it.

[0051] Among them, the smoke elimination tube 203 is fixed above the smoke blowing tube 202, and the smoke inside the smoke blowing tube 202 enters the interior of the smoke elimination tube 203 through the baffle 2032. The surface array of the baffle 2032 is provided with a plurality of curved grooves 2033, and the curved grooves 2033 penetrate the baffle 2032. The water vapor above converges into a water flow and then flows to the baffle 2032 through the landslide 2031, and falls into the interior of the smoke blowing tube 202 below through the curved grooves 2033.

[0052] When the power of the diesel generator set 100 is low, the smoke generated is small, the cooling spray assembly 300 does not work, and the smoke below enters the upper smoke elimination tube 203 through the disk 2035 and the flap 2036 in the middle of the baffle 2032, and is adsorbed by the upper first filter layer 204 and then discharged to the outside. When the smoke below passes through the curved groove 2033 on the surface of the baffle 2032, as shown in FIG. Figure 4 As shown, when entering the upper arc portion on the right side of the curved groove 2033, it is necessary to pass through the lower arc portion on the left side to pass through the curved groove 2033 and enter the top of the baffle 2032. However, there will be residual water in the lower arc portion on the left side of the curved groove 2033, which will block the curved groove 2033, resulting in the smoke being unable to pass through the curved groove 2033 and can only move upward from the middle part of the baffle 2032, ensuring that the smoke passes through the first filter layer upward in the most direct path.

[0053] When the power of the diesel generator set 100 is relatively large, there is more smoke at this time. The smoke is guided by the guide plate 2022 inside the smoke blowing tube 202, and the flow speed of the smoke is accelerated. The smoke passes through the upper disc 2035 and the flap 2036, and the flap 2036 is blown to flip the angle. When there is less smoke, the flap 2036 is almost vertical to a horizontal state. After passing through the flap 2036, the smoke no longer goes straight up, but is guided by the flap 2036 to float in all directions. At this time, the cooling spray assembly 300 works, and the spray pipe 303 sprays water inside. The smoke floats around and mixes with the water vapor more conveniently, effectively reducing the concentration of pollutants in the smoke. At the same time, the collected sewage flows downward through the curved groove 2033, completely blocking the curved groove 2033, and the smoke cannot pass through the curved groove 2033.

[0054] Reference Figure 6 , Figure 7 A mounting plate 2038 is also provided on the inner wall of the smoke exhaust tube 203, and a fixing opening 2039 is penetrated through the end surface of the mounting plate 2038. An opening 2041 is penetrated through the end surface of the first filter layer 204, and a fixing column 2042 is provided on the end of the opening 2041. The end of the fixing column 2042 extends to the inner wall of the fixing opening 2039. A second filter layer 2043 and a third filter layer 2044 are arranged in an array at the end of the first filter layer 204.

[0055] Among them, there are also a second filter layer 2043 and a third filter layer 2044 above the first filter layer 204. The second filter layer 2043 and the third filter layer 2044 have the same structure as the first filter layer 204. The difference lies in the different internal adsorption materials. The first filter layer 204 filters large particles in the smoke, the second filter layer 2043 adsorbs harmful substances in the smoke, and the third filter layer 2044 further filters tiny particles to make the smoke meet the emission standards.

[0056] The fixing column 2042 below the first filter layer 204 can be inserted into the fixing port 2039 on the surface of the mounting plate 2038, and the fixing column 2042 corresponds to the fixing port 2039. At the same time, the fixing column 2042 below the second filter layer 2043 can be inserted into the opening 2041 on the upper surface of the first filter layer 204, and so on. The three filter layers are installed as a whole and fixed on the upper surface of the mounting plate 2038.

[0057] like Figure 8 As shown, preferably, a locking column 205 is movably provided inside the third filter layer 2044, a receiving groove 2051 is provided on the outer wall of the locking column 205 and a movable cavity 2052 is provided at the end of the locking column 205, a push column 2053 is movably provided inside the locking column 205, a limiting rod 2054 is hingedly connected to the outer wall of the push column 2053 and the limiting rod 2054 is located on the inner wall of the receiving groove 2051, and a first elastic member 2055 is also provided at the end of the push column 2053.

[0058] Among them, the locking column 205 passes through the three filter layers and is inserted from the opening 2041 on the surface of the third filter layer 2044. The bottom of the locking column 205 passes through the fixing port 2039 of the mounting plate 2038. The limiting rod 2054 at the bottom of the locking column 205 opens outward and is close to the bottom surface of the mounting plate 2038, fixing the three filter layers above the mounting plate 2038.

[0059] In summary, when in use, the three filter layers are penetrated by the locking column 205, and the three filter layers are fixed on the surface of the mounting plate 2038, so that the smoke inside the smoke exhaust pipe 203 is adsorbed and filtered. The smoke generated by the operation of the diesel generator set 100 enters the smoke blowing pipe 202 through the smoke inlet pipe 2021, and moves upward in a swirling manner after being guided by the guide plate 2022, thereby accelerating the flow speed of the smoke. The smoke enters the smoke exhaust pipe 203 through the middle part of the baffle 2032.

[0060] When the power of the generator set is low, the smoke enters the smoke elimination tube 203 through the gap between the disc 2035 and the flap 2036. At the same time, the curved groove 2033 is blocked by the accumulated water in the lower arc part on the left side, and the smoke can only move upward from the middle part of the baffle 2032, and is discharged after being adsorbed and filtered by the first filter layer 204, the second filter layer 2043 and the third filter layer 2044 above.

[0061] When the power of the generator set is large, the flow speed of the smoke is accelerated, blowing the flap 2036 to flip, and the flap 2036 is tilted to the horizontal direction. At this time, the smoke below is dispersed to the surroundings through the flap 2036, and no longer disperses directly upward, thereby increasing the movement path of the smoke inside the smoke exhaust tube 203. At this time, the cooling spray assembly 300 works, and the spray pipe 303 sprays water to mix with the smoke. Since the smoke moves to the surroundings through the flap 2036, the contact volume between the water vapor and the smoke is increased, the adsorption effect of the water vapor on the pollutants is increased, and the pollutant concentration in the remaining smoke is reduced. After passing through the water vapor, the remaining pollutants continue to move upward, pass through the first filter layer 204, the second filter layer 2043 and the third filter layer 2044, and the sewage after the water vapor that adsorbs the pollutant particles flows downward through the curved groove 2033. At the same time, the sewage completely blocks the curved groove 2033, and the smoke cannot pass through the curved groove 2033 upward.

[0062] Example 3

[0063] This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0064] Specifically, refer to Figure 2 , Figure 3 and Fig. 9 The spray pipe 303 array is arranged on the inner wall of the smoke elimination tube 203 and located at the end of the baffle 2032. The spray pipe 303 outer wall array is provided with a spray port 3031. The water collecting tube 304 is fixed to the end of the smoke blowing tube 202. The end of the water collecting tube 304 is provided with a drain pipe 3041, and the inner wall of the drain pipe 3041 is provided with a pipe opening 3042.

[0065] Among them, Figure 2 As shown, the water supply tank 301 is installed on the side of the fixed frame 201, and water is supplied to the spray pipe 303 through the water supply pipe 302. The water supply pipe 302 is wrapped around the outside of the chimney 202. When the diesel generator set 100 operates at a large power, the chimney 202 is cooled. At the same time, the water that has absorbed heat will also enter the interior of the spray pipe 303, and form water vapor through the spray port 3031 to spray on the interior of the chimney 203. The spray pipe 303 is between the baffle 2032 and the first filter layer 204. The water vapor formed by the spray port 3031 covers the entire bottom of the first filter layer 204, effectively absorbing the pollutant particles in the smoke.

[0066] The water collecting cylinder 304 is fixed at the bottom of the chimney 202 . After the particulate matter is adsorbed, the sewage flows into the chimney 202 through the curved groove 2033 , and then is collected in the water collecting cylinder 304 below and enters the drainage pipe 3041 .

[0067] Preferably, refer to Fig. 9 , Fig.10A concave plate 305 is also provided on the inner wall of the drain pipe 3041, a slide groove 3051 is opened on the inner wall of the concave plate 305 and a cylinder 3052 is provided on the end face of the concave plate 305, a second elastic member 3053 is sleeved on the outer wall of the cylinder 3052 and a sleeve 3054 is sleeved on the end of the second elastic member 3053, a round block 3055 is provided on the end of the sleeve 3054 and the outer wall of the round block 3055 contacts the outer wall of the pipe mouth 3042.

[0068] Among them, the concave plate 305 is fixed inside the drain pipe 3041, and the sleeve 3054 is sleeved on the outside of the top of the cylinder 3052. The sleeve 3054 is pushed upward by the second elastic member 3053, so that the round block 3055 on the top is in close contact with the pipe mouth 3042 on the inner wall of the drain pipe 3041. When there is no water or very little water inside the water collecting tube 304, the pipe mouth 3042 is blocked by the round block 3055 to prevent part of the smoke from moving downward after entering the smoke blowing tube 202 and flowing to the outside through the water collecting tube 304.

[0069] A connecting rod 3056 is hinged on the outer wall of the sleeve 3054, and a slider 3057 is hinged on the end of the connecting rod 3056. A slide plate 3058 is provided on the outer wall of the slider 3057, and the end of the slide plate 3058 extends to the inner wall of the slide groove 3051 and slidably cooperates therewith. A protrusion 3059 is also fixed on the end face of the slider 3057.

[0070] Among them, the connecting rod 3056 is symmetrically provided with two hinges on the outside of the sleeve 3054, and a slider 3057 is hinged at the bottom end of the connecting rod 3056. The slider 3057 slides on the inner wall of the concave plate 305. Pushed by the second elastic member 3053, the sleeve 3054 is pushed upward, and the sliders 3057 on both sides are located at the inner positions on both sides of the concave plate 305. When the sewage inside the water collecting cylinder 304 is collected, the sewage accumulates inside the drain pipe 3041, causing the round block 3055 to move downward, and a gap appears between it and the pipe mouth 3042. The sewage is discharged downward through the gap. When the round block 3055 moves downward, the bottoms of the connecting rods 3056 on both sides slide to both sides, and the sliders 3057 slide to the outside of the slide groove 3051.

[0071] Better, refer to Figure 9~Figure 12 A turntable 306 is movably provided at the end of the concave plate 305 and an inclined groove 3061 is provided on the end surface of the turntable 306. The end of the convex column 3059 extends to the inner wall of the inclined groove 3061. A movable groove 3062 is provided at the end of the turntable 306 away from the inclined groove 3061. A clamping plate 3063 is arranged in an array at the end of the turntable 306 and a sliding rod 3064 is arranged at the end of the clamping plate 3063. A fixing plate 3065 is arranged at the end of the clamping plate 3063. A movable groove 3066 is provided in an array on the end surface of the fixing plate 3065. One end of the sliding rod 3064 extends to the inner wall of the movable groove 3062, and the other end extends to the inner wall of the movable groove 3066. A bellows 307 is also fixed to the end of the drain pipe 3041.

[0072] Among them, the fixing plate 3065 is fixed to the inner wall of the drain pipe 3041, and a plurality of the clamping plates 3063 are installed on the top of the fixing plate 3065. The clamping plates 3063 cooperate with each other. The turntable 306 is installed on the top of the clamping plates 3063 and fits the bottom surface of the concave plate 305. The inclined groove 3061 on the upper surface of the turntable 306 cooperates with the slider 3057. The convex column 3059 on the surface of the slider 3057 extends into the inside of the inclined groove 3061. When the round block 3055 moves downward, the slider 3057 slides to both sides inside the concave plate 305, and the convex column 3059 slides inside the inclined groove 3061. Fig.10 As shown, the protruding column 3059 slides from the inner side of the inclined groove 3061 to the outside inside the inclined groove 3061. Since the sliding block 3057 is restricted by the concave plate 305, the turntable 306 below rotates.

[0073] When the turntable 306 rotates, the lower clamping plate 3063 is affected by the rotation of the turntable 306, and the sliding bar 3064 on the surface of the clamping plate 3063 slides from the middle of the movable groove 3062 to the end point of the movable groove 3062 inside the movable groove 3062. At the same time, the lower end of the sliding bar 3064 slides from the inner groove end to the outer groove end of the movable groove 3066 inside the movable groove 3066. At this time, the clamping plates 3063 move outward and away from each other. At this time, the sewage above can flow downward through the space between the clamping plates 3063.

[0074] The bellows 307 is installed at the bottom of the drain pipe 3041. The sewage finally enters the inside of the bellows 307 through the drain pipe 3041. The other end of the bellows 307 is connected to the sewage treatment pool, and the sewage finally gathers in the sewage treatment pool.

[0075] When the operating power of the diesel generator set 100 is relatively large, the cooling spray assembly 300 will be turned on, and the sewage will eventually be discharged through the bellows 307. At this time, the bellows 307 is full of sewage and continues to flow. When the operating power of the diesel generator set 100 is relatively low, the cooling spray assembly 300 will not be turned on, and the interior of the smoke elimination tube 203 will not produce water vapor and smoke mixing. At this time, the interior of the bellows 307 is as follows. Fig.12 As shown, sewage accumulates in the lower ring section of the bellows 307, while the upper ring section is a cavity.

[0076] The cavities between the multiple upper ring sections form an air lock, and when the cooling spray assembly 300 is not turned on, the sewage in the lower ring section of the bellows 307 is retained inside the bellows 307. Since sewage accumulates inside the drain pipe 3041, the round block 3055 needs to be pushed downward. Therefore, the elastic force of the second elastic member 3053 is limited. Although the diesel generator set 100 generates less smoke when running at low power and the flow rate is slower than when running at a higher power, it is still possible to impact the round block 3055 to cause it to open downward. Part of the smoke passes through the drain pipe 3041 downward, through the plywood 3063 and into the bellows 307. At this time, the air lock formed by the multiple cavities in the bellows 307 can effectively prevent this part of the smoke from pushing the sewage in the lower ring section, so that the smoke and sewage are mixed until the cooling spray assembly 300 is turned on and enters the sewage treatment step together with the sewage, thereby preventing the smoke from being discharged to the outside through the drain pipe 3041 to cause environmental pollution.

[0077] In summary, when in use, the sewage after the water vapor sprayed by the spray pipe 303 mixes with the smoke flows downward into the chimney 202 through the curved groove 2033, and the sewage is collected in the water collecting tube 304 and enters the drain pipe 3041. When there is no water accumulation or little water accumulation in the water collecting tube 304, the round block 3055 is tightly attached to the pipe mouth 3042 under the action of the second elastic member 3053, so as to prevent the smoke inside the chimney 202 from leaking through the drain pipe 3041.

[0078] When the amount of water accumulated inside the drain pipe 3041 increases, the round block 3055 drops due to the weight of the water, resulting in a gap between the round block 3055 and the pipe opening 3042 , and sewage flows downward through the gap between the round block 3055 and the pipe opening 3042 .

[0079] When the round block 3055 moves downward, the connecting rods 3056 on both sides move toward both sides, and the slider 3057 slides outward in the concave plate 305, driving the convex column 3059 inside the slider 3057 to slide in the inclined groove 3061 on the upper surface of the turntable 306, driving the turntable 306 to rotate. When the turntable 306 rotates, the closing plate 3063 slides in the movable groove 3062 and the movable groove 3066 through the sliding rod 3064, moving away from each other to form a drainage channel, and the sewage falling from above enters the bellows 307 below.

[0080] When the power of the diesel generator set 100 is low, the cooling spray assembly 300 is not started, and the sewage inside the bellows 307 is accumulated in the lower ring section, and the upper ring section forms a cavity, and the cavities of multiple upper ring sections form a multi-segment cavity air lock.

[0081] If the smoke generated by the diesel generator set 100 impacts the circular block 3055 to make it fall, part of the smoke may enter the bellows 307. However, the air lock prevents the smoke from pushing the lower ring section sewage, and the smoke is mixed with the lower ring section sewage to prevent the smoke from being discharged to the outside through the bellows 307 without being treated, until the cooling spray assembly 300 is started, and then the sewage inside the bellows 307 enters the sewage treatment step together with the sewage falling from above.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
