[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1, as Figure 1 and Figure 2 As shown, a smoke emission treatment device for straw burning includes a shell 1, support legs 2 are fixedly connected to the four corners of the lower end of the shell 1, a control box 3 is fixedly installed at the front end of the shell 1, a pretreatment component 4 is arranged on the right part of the inner surface of the shell 1, and a filter component 5 is arranged on the inner surface of the shell 1 to the left of the pretreatment component 4.

[0020] During the implementation of this embodiment, the control box 3 allows the smoke from the straw burning to be sucked into the outer shell 1 through the pretreatment component 4, and then the pretreatment component 4 uses a cyclone separation method to separate the large particles of debris in the smoke. The separated smoke is then cooled, and the pretreated smoke is filtered for a second time by the filter component 5 using a combination of dry and wet methods.

[0021] The control box 3 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its internal structure, connection method and principle are not further explained.

[0022] Specifically, in order to separate and cool the straw flue gas into large particles, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the pretreatment component 4 includes a collecting box 41 fixedly connected to the lower part of the inner surface of the shell 1, a separation mechanism 42 is provided on the upper end of the collecting box 41 and the inner surface of the shell 1, a water cooling mechanism 43 is provided on the lower part of the inner surface of the shell 1 and located on the left side of the collecting box 41, and a knocking mechanism 44 is provided on the upper part of the inner surface of the shell 1.

[0023] For further information, see Figure 3 and Figure 4 In this embodiment, the separation mechanism 42 includes a cyclone separator 421 fixedly connected to the upper end of the collecting box 41, the cyclone separator 421 is fixedly connected to the inner surface of the outer shell 1, a fan 422 is fixedly connected to the right part of the inner surface of the outer shell 1, the inner surface of the fan 422 and the inner surface of the cyclone separator 421 are jointly fixedly connected with a connecting pipe 423, an air outlet pipe 424 is fixedly connected to the upper end of the cyclone separator 421, and the front end of the fan 422 penetrates and extends to the right end of the outer shell 1 and is fixedly connected with an air inlet pipe 425.

[0024] During the implementation process, it is connected to the smoke duct of straw burning through the air inlet pipe 425, and then the fan 422 is started so that the operation of the fan 422 allows the smoke to enter the cyclone separator 421 through the connecting pipe 423. Since the smoke performs a spiral motion inside the cyclone separator 421, the large particles of impurities in the smoke move downward to the collection box 41. The smoke after the first separation enters the air outlet pipe 424 through the cyclone separator 421.

[0025] The cyclone separator 421 mentioned above is a mature separation technology means and equipment in the prior art. In this solution, it is used to separate large particle impurities in the flue gas, and its internal structure, principle and connection method are not further explained.

[0026] It should be noted that this solution only processes the particulate impurities in the flue gas from burning straw, and the harmful gases in the flue gas can be processed again by other related equipment.

[0027] For further information, see Figure 3 and Figure 5 In this embodiment, the water cooling mechanism 43 includes a hollow tube 431 sleeved on the outer surface of the air outlet pipe 424, the outer surface of the hollow tube 431 is fixedly connected to the inner surface of the shell 1, the lower part of the inner surface of the shell 1 is fixedly connected to a water tank 433, the upper part of the inner surface of the water tank 433 penetrates and extends to the inner surface of the hollow tube 431 and is fixedly connected to a water inlet pipe 435, the lower end of the water inlet pipe 435 is fixedly connected to a water pump 434, a plurality of spiral rings 432 are linearly and equidistantly distributed and fixedly connected to the inner surface of the hollow tube 431, and a water outlet pipe 436 is fixedly connected to the inner surface of the water inlet pipe 435.

[0028] During the implementation process, after the flue gas after the initial separation enters the air outlet pipe 424, the water pump 434 is started so that the water pump 434 draws water from the water tank 433 and enters the inner cavity of the hollow tube 431 through the water inlet pipe 435. Under the action of the spiral ring 432, the water flows in a spiral form to cool the flue gas after the initial separation by heat transfer, which can not only effectively reduce the flue gas temperature and reduce thermal pollution to the environment, but also improve the cohesion of the smoke through cooling, which helps to remove smoke particles and reduce the emission of harmful substances, thereby achieving the effect of improving air quality and reducing environmental pollution.

[0029] For further information, see Figure 3 and Figure 6 In this embodiment, the knocking mechanism 44 includes a fixed rod 441 fixedly connected to the upper inner surface of the shell 1, the rear part of the inner surface of the water inlet pipe 435 penetrates and extends to the rear end of the fixed rod 441 and is rotatably connected to a water wheel blade rod 442, the outer surface of the water wheel blade rod 442 is fixedly connected to a cam 443, the inner surface of the fixed rod 441 is rotatably connected to a round rod 444, the left and right ends of the round rod 444 are fixedly connected to a semicircular block 445, and the outer surface of the round rod 444 is sleeved with a reset spring 446, and the two ends of the reset spring 446 are respectively fixedly connected to the left end of the fixed rod 441 and the right end of the semicircular block 445 located on the left, and the inner surface of the water inlet pipe 435 is fixedly connected to an inclined block 447 below the water wheel blade rod 442.

[0030] During the implementation process, during the water pumping process, the movement of the water flow will be caused by the action of the inclined block 447, so that the water flow can impact the water wheel blade 442, and then drive the cam 443 to rotate, and the cam 443 can intermittently squeeze the semicircular block 445 on the left, and push the round rod 444 to slide on the inner surface of the fixed rod 441, so that the return spring 446 is in a compressed state, and then squeeze the semicircular block 445 on the right to knock the outer shell 1 of the cyclone separator 421, so that the cyclone separator 421 vibrates, which can enhance the working efficiency of the cyclone separator 421, help it to separate smoke particles more effectively, improve the smoke purification effect, and accelerate the sedimentation and aggregation of smoke through the action of vibration, reduce the emission of harmful substances, and help reduce environmental pollution.

[0031] Embodiment 2: Based on Embodiment 1, this embodiment adds a filter component 5 for capturing small particles in the straw smoke, thereby achieving the purpose of capturing small particles in the straw smoke.

[0032] Specifically, in order to capture small particles in straw smoke, refer to Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10In this embodiment, the filter assembly 5 includes a cylinder 51 fixedly connected to the inner surface of the outer shell 1, a spray mechanism 52 is provided on the upper inner surface of the cylinder 51, a filter mechanism 53 is provided on the inner surface of the cylinder 51 below the spray mechanism 52, and a collection mechanism 54 is provided on the inner surface of the cylinder 51 below the filter mechanism 53.

[0033] For further information, see Figure 3 , Figure 7 and Figure 8 In this embodiment, the spray mechanism 52 includes a fixed shell 521 fixedly connected to the upper inner surface of the cylinder 51, the inner surface of the fixed shell 521 is connected to the inner surface of the water inlet pipe 435, the inner surface of the fixed shell 521 is rotatably connected to a turbine 522, the lower end of the turbine 522 is fixedly connected to a rotating rod 523, the outer surface of the rotating rod 523 is fixedly connected to a hollow block 524, a plurality of spray pipes 525 are fixedly connected to the inner surface of the hollow block 524 at equal intervals in an annular manner, a rotating ring 526 is rotatably connected to the upper inner surface of the hollow block 524, and a connecting pipe 527 is fixedly connected to the left portion of the inner surface of the fixed shell 521 and extends to the lower end of the rotating ring 526.

[0034] For further information, see Figure 3 and Fig. 9 In this embodiment, the filtering mechanism 53 includes a fixed block 531 which is symmetrically fixed to the inner surface of the cylinder 51, the upper ends of the two fixed blocks 531 are fixedly connected to a spring telescopic rod 532, the upper ends of the two spring telescopic rods 532 are commonly fixedly connected to a filter screen 533 which is slidably connected to the rotating rod 523, the lower end of the filter screen 533 is fixedly connected to a circular groove block 534, the outer surface of the rotating rod 523 is located below the circular groove block 534 and is fixedly connected to a connecting block 535, and the upper end of the connecting block 535 is fixedly connected to a squeezing ball 536.

[0035] During the implementation process, the cooled smoke will enter the inner cavity of the cylinder 51 and will continuously move upward. During the movement, the smoke will first pass through the filter screen 533 to filter the impurities in the smoke, and the impurities will be retained at the lower end of the filter screen 533. After being filtered by the filter screen 533, the smoke will continue to move upward. The water used for cooling will enter the fixed shell 521 through the water outlet pipe 436 to impact the turbine 522, so that the turbine 522 rotates and drives the rotating rod 523 to rotate, so that the squeezing ball 536 on the rotating rod 523 can squeeze the impurities during the rotation. The circular groove block 534 allows the filter 533 to move up and down under the action of the spring telescopic rod 532, generating vibration to clean up the filtered impurities. By regularly cleaning the impurities accumulated on the filter 533, the permeability of the filter 533 is ensured to avoid reducing the filtering effect due to blockage. The filter 533 can effectively remove debris and sediments to prevent them from entering the flue gas flow again, ensuring that the flue gas can be more thoroughly purified when passing through the filter 533, maintaining the stability of the filtering effect, and helping to improve the purification efficiency of the flue gas, thereby effectively reducing harmful substances in the flue gas.

[0036] Secondly, the water that drives the turbine 522 to rotate will enter the hollow block 524 through the connecting pipe 527, and then enter the inner cavity of the spray pipe 525 to be sprayed out through the spray pipe 525, so that the water mist can rotate to perform a wet filtering operation on the air filtered by the filter net 533, and the filtered flue gas is discharged through the pipe at the upper end of the cylinder 51, which effectively captures the tiny particles and harmful substances remaining in the air, can improve the flue gas purification effect, further reduce the emission of harmful particles, reduce the pollution to the air quality, and also help to reduce the concentration of inhalable particles and toxic gases in the air, and improve the environmental quality.

[0037] The turbine 522 mentioned above is a mature hydrodynamic component in the prior art. In this solution, its function of rotating under the action of water flow is utilized, and its internal structure, principle and connection method are not further explained.

[0038] For further information, see Figure 3 and Fig. 9 In this embodiment, a plurality of return springs 537 are linearly and equidistantly distributed and fixedly connected to the inner surface of the connecting block 535. The upper ends of the plurality of return springs 537 are commonly and fixedly connected to a scraper 538 which is slidably connected to the connecting block 535. The upper end of the scraper 538 is in close contact with the lower end of the filter screen 533.

[0039] During the implementation process, the rotation of the rotating rod 523 will drive the connecting block 535 to rotate, so that the scraper 538 can always be tightly attached to the lower end of the filter 533 for rotation and scraping under the action of the reset spring 537 and the vibration, which helps to continuously remove the smoke and impurities accumulated on the surface of the filter 533, ensuring that the filter 533 always maintains a high filtering capacity. Through the scraping of the scraper 538, the filter 533 can clean up the retained particulate matter in time to avoid clogging the filter 533, thereby improving the flue gas purification efficiency and reducing the emission of pollutants.

[0040] For further information, see Figure 3 and Fig.10 In this embodiment, the collecting mechanism 54 includes an inclined plate 541 fixedly connected to the inner surface of the cylinder 51, the upper end of the inclined plate 541 penetrates and extends to the inner surface of the collecting box 41 and is fixedly connected to a return pipe 542, the outer surface of the return pipe 542 is fixedly connected to an L-shaped plate 543, the left end of the L-shaped plate 543 is fixedly connected to a spring telescopic rod 544, the left end of the spring telescopic rod 544 is fixedly connected to a blocking ball 545, and the outer surface diameter of the blocking ball 545 is larger than the inner surface diameter of the return pipe 542.

[0041] During the implementation process, the impurities cleaned from the filter 533 will fall on the inclined plate 541 under the action of gravity, and the sewage generated by the spray pipe 525 will also be concentrated on the inclined plate 541 through the filter 533, and will enter the return pipe 542 through the inclined plate 541. As the water level continues to increase, the pressure will continue to increase, pushing the blocking ball 545 to gradually squeeze the spring telescopic rod 2 544, so that the blocking ball 545 will be away from the return pipe 542, and the right end of the return pipe 542 will be opened. At this time, the sewage and dust will once again enter the collection box 41 and gather together with the dust separated by the cyclone separator 421, and then can be uniformly discharged through the pipeline at the lower end of the collection box 41, effectively recycling the pollutants and sewage cleaned up, avoiding the occurrence of secondary pollution, and collecting the pollutants in a centralized manner for unified treatment and discharge. In this way, not only the efficient operation of the emission system is ensured, but also environmental pollution can be reduced, the treatment effect of smoke and dust emissions can be improved, and the negative impact on air and water resources can be reduced.

[0042] Working process: When in use, the flue gas is preliminarily treated by the separation mechanism 42, and then the high-temperature flue gas is continuously cooled down by the water cooling mechanism 43. During the cooling process, the cyclone separator 421 in the separation mechanism 42 is vibrated by the knocking mechanism 44, and then the flue gas is filtered again by the spraying mechanism 52 and the filtering mechanism 53. During the filtering process, the impurity particles filtered out and the sewage will be returned to the collection box 41 through the collecting mechanism 54.
