[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0047] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof. Embodiment 1

[0048] like Figure 1 , 2 As shown, the present invention provides a spraying device for industrial waste gas treatment, comprising:

[0049] A shell 1, in which a spray water collection unit 2, a spray unit 3, an activated carbon filler layer 4 and a guide fan 5 are arranged in sequence from bottom to top, and an exhaust pipe 8 is arranged on the top of the shell 1;

[0050] A first circulation pipeline 6, wherein the water outlet end of the first circulation pipeline 6 is connected to the spray unit 3, and the two water inlet ends of the first circulation pipeline 6 are respectively connected to the spray water collection unit 2 and the water supply device;

[0051] The second circulation pipeline 7, the air outlet end of the second circulation pipeline 7 is connected to the air inlet at the bottom of the shell 1, and the two air inlet ends of the second circulation pipeline 7 are respectively connected to the top of the shell 1 and the exhaust gas pipeline.

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The present invention provides a spraying device for treating industrial waste gas. When in use, the industrial waste gas is introduced from the air inlet at the bottom of the shell 1, and the waste gas flows upward, passes through the spray unit 3 and is fully contacted with the spray water for cooling and dust reduction, and the waste gas after spraying further flows upward, passes through the activated carbon filler layer 4 for filtration and purification, and the purified waste gas is discharged through the exhaust pipe 8 at the top of the shell 1. Two sets of circulation pipelines are arranged on the shell 1, and the first circulation pipeline 6 is used for the circulation of spray water. After spraying, the spray water falls into the spray water collection unit 2, and is driven by the pump body to flow back to the spray unit 3 through the first circulation pipeline 6 for spraying again. A filter is arranged on the reflux path to remove particulate matter in the spray water. The second circulation pipeline 7 is used for the circulation of waste gas. The waste gas after spraying and activated carbon purification is not directly discharged from the exhaust pipe 8, but flows back to the bottom of the shell 1 through the second circulation pipeline 7 for circulation treatment.

[0054] The present invention provides a spraying device for treating industrial waste gas, which effectively realizes the purification of industrial waste gas. Through the setting of two groups of circulation pipelines, on the one hand, the spraying water is recycled to reduce the amount of spraying water, and on the other hand, the industrial waste gas is circulated for treatment, and multiple spraying and filtering are performed to improve the cleanliness of the waste gas and improve the treatment effect of the equipment.

[0055] The exhaust pipe 8 and the air inlet end of the second circulation pipeline 7 are respectively arranged on both sides of the guide fan 5, and the top of the housing 1 is connected to a motor 9 for driving the guide fan 5 to rotate. The motor 9 drives the guide fan 5 to rotate and provides power for the exhaust gas flow. Embodiment 2

[0056] like Figure 1 , 4 As shown, based on the above-mentioned embodiment 1, the spray unit 3 includes an upper spray pipe 11 and a side spray pipe 12, and the two side spray pipes 12 are symmetrically connected to both sides of the upper spray pipe 11 to form a downwardly expanded spray surface, and the upper spray pipe 11 and the side spray pipe 12 are connected to the water outlet end of the first circulation pipeline 6.

[0057] The working principle and beneficial effects of the above technical solution are:

[0058] The upper nozzle 11 and the side nozzle 12 of the spray unit 3 can be arranged in parallel in multiple numbers. After the spray water enters the upper nozzle 11 and the side nozzle 12, it is sprayed downward through the nozzles thereon. The nozzles can be set as atomizing nozzles to form a downwardly expanded spray surface, so that the spray water is evenly in contact with the exhaust gas after being sprayed, thereby improving the cooling and dust removal effect of the spray water. Embodiment 3

[0059] like Figure 1 , 2 As shown, on the basis of the above-mentioned embodiment 1, a filter plate 10 is arranged above the spray water collecting unit 2, and a plurality of filter holes are arranged at the center of the filter plate 10.

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] A filter plate 10 is provided on the spray water collection unit 2, and the industrial waste gas is filtered for the first time through the filter plate 19. When the industrial waste gas passes through the filter hole, the large particle impurities mixed in the industrial waste gas are removed, reducing the burden of subsequent purification of the activated carbon filler layer 4 and extending the service life of the activated carbon filler layer 4.

[0062] Embodiment 4:

[0063] like Figure 1 As shown, based on the above embodiment 1, the spray water collection unit 2 includes:

[0064] A spray water collection box 21, which is disposed at the bottom of the housing 1, and a gap is provided between the spray water collection box 21 and the side wall of the housing 1;

[0065] A water receiving plate 22, the water receiving plate 22 is slidably connected to the inner wall of the spray water collecting box 21, the water outlet on the side wall of the spray water collecting box 21 is connected to the water inlet end of the first circulation pipeline 6, and the water outlet on the side wall of the spray water collecting box 21 is located below the water receiving plate 22, and an elastic booster component 23 supporting the water receiving plate 22 is provided on the other side of the spray water collecting box 21;

[0066] The guide column 24 is connected to the bottom end of the spray water collection box 21 , and the guide column 24 is slidably connected to the guide hole 25 at the bottom end of the spray water collection box 21 .

[0067] The bottom end of the spray water collection box 21 is connected to a blocking block 26 , which is disposed above the air inlet at the bottom of the shell 1 .

[0068] The working principle and beneficial effects of the above technical solution are:

[0069] When the exhaust gas is not introduced, the blocking block 26 at the bottom of the spray water collection box 21 blocks the air inlet of the shell 1. When the exhaust gas is introduced, as the exhaust gas pressure gradually increases, the blocking block 26 at the bottom of the spray water collection box 21 is lifted up, the spray water collection box 21 moves upward, and the guide column 24 slides along the inner wall of the guide hole 25 to guide the spray water collection box 21; thus, the introduced exhaust gas can maintain the preset pressure, and after the exhaust gas enters the shell 1, it flows upward through the gap between the spray water collection box 21 and the shell 1. The spray water collecting unit is arranged at the bottom of the shell 1. When the spray water passes through the filter hole plate 10, it flows downward through the filter hole and falls down with the filtered large particles of impurities at the same time, and enters the collection space formed by the water receiving plate 22 and the upper part of the spray water collecting box 21, so as to collect the spray water and large particles of impurities; the elastic booster component 23 provides elastic force for the water receiving plate 22. As the amount of water increases, the weight above the water receiving plate 22 gradually increases, and it slides downward along the inner wall of the spray water collecting box 21. When the water amount exceeds the preset value, the water receiving plate 22 moves to a position lower than the water outlet of the side wall of the spray water collecting box 21, so that the spray water above the water receiving plate 22 flows out through the water outlet; when the water amount above the water receiving plate 22 is lower than the preset value, it is reset upward under the action of the elastic force.

[0070] Through the above-mentioned structural design, the industrial waste gas is pressurized, so that the waste gas can maintain sufficient power when it is introduced, so that it can flow through the subsequent spraying and purification areas. The movable water receiving plate 22 is used to receive the spray water, and the spray water is discharged when the spray water reaches a preset amount, ensuring that the amount of water discharged in a single time is consistent, which is convenient for the power control of the subsequent spray water cycle. Embodiment 4

[0071] like Figure 3 As shown, based on the above-mentioned embodiment 4, the elastic booster component 23 includes:

[0072] A guide sleeve 31, which is disposed in a side slide groove 30 on a side wall of the spray water collection box 21;

[0073] A booster slide bar 32, the booster slide bar 32 is horizontally slidably connected to the guide sleeve 31, one end of the booster slide bar 32 close to the housing 1 is connected to a slide ball 33, a spring is sleeved on the booster slide bar 32, and both ends of the spring are respectively connected to the guide sleeve 31 and the slide ball 33;

[0074] A first boost chute 34, which is disposed on the side wall of the housing 1, wherein the bottom of the first boost chute 34 is disposed as an inclined surface, and the depth of the lower portion of the first boost chute 34 is greater than the depth of the upper portion, and the sliding ball 33 is slidably connected in the first boost chute 34;

[0075] A support plate 35, the support plate 35 is connected to the side wall of the housing 1, the support plate 35 slides relative to the side slide groove 30 and extends into the spray water collection box 21, and a second boosting slide groove 36 is provided on the upper part of the extended end of the support plate 35;

[0076] A first boosting block 37, which is connected to the bottom end of the water receiving plate 22 and is close to the side slide groove 30;

[0077] The second boost block 38 is slidably connected in the second boost slide groove 36 , and the side surfaces of the first boost block 37 and the second boost block 38 are provided with relatively sliding inclined surfaces, and the second boost block 38 is connected to the end of the boost slide rod 32 .

[0078] The working principle and beneficial effects of the above technical solution are:

[0079] When the pressure of the exhaust gas increases, the spray water collecting box 21 moves upward, and the spray water collecting box 21 moves upward relative to the support plate 35, driving the guide sleeve 31 and the boosting slide bar 32 to move upward, and the slide ball 33 on the boosting slide bar 32 slides upward along the first boosting slide bar 34. As the depth of the first boosting slide bar 34 gradually becomes shallower from bottom to top, its force on the boosting slide bar 32 and the spray water collecting box 21 gradually increases, and the pressure of the spray water collecting box 21 on the exhaust gas also increases, maintaining a continuous boosting state for the exhaust gas, and reducing the jitter caused by the sudden pressure drop when the exhaust gas flows out from the gap between the spray water collecting box 21 and the shell 1. As the amount of water above the water receiving plate 22 increases, the overall weight of the spray water collection box 21 increases. At this time, the water receiving plate 22 does not slide, and the spray water collection box 21 slides downward as a whole, driving the boost slide bar 32 to move downward; as the amount of water above the water receiving plate 22 further increases, the water receiving plate 22 overcomes the spring force and slides downward, the inclined surface of the first boost block 37 squeezes the inclined surface of the second boost block 39, pushing the boost slide bar 32 to move out of the spray water collection box 21, and the slide ball 33 slides downward along the first boost slide groove 34 until it reaches the deepest part of the bottom of the first boost slide groove 34, thereby re-blocking the air inlet at the bottom of the shell 1; after obtaining the blocking state signal through sensor detection, the spraying action of the spray unit 3 is stopped, so that the spray water no longer flows into the spray water collection box 21.

[0080] Through the above-mentioned structural design, as the height of the spray water collection box 21 increases, the pressure of the shell 1 on it gradually increases, maintaining a continuous pressurized state for the exhaust gas, and reducing the jitter caused by the sudden pressure drop when the exhaust gas flows out from the gap between the spray water collection box 21 and the shell 1; when the spray water refluxes, the position of the spray water collection box 21 is consistent, achieving a consistent spray water reflux state, and ensuring the accuracy of the amount of refluxed spray water. Embodiment 5

[0081] like Figure 5 As shown, based on the above-mentioned embodiment 3, a plurality of cleaning rods 27 are connected to the top of the water receiving plate 22, and the cleaning rods 27 are arranged one by one corresponding to the plurality of filter holes of the filter hole plate 10, and the diameter of the cleaning rods 27 is smaller than the diameter of the filter holes.

[0082] The working principle and beneficial effects of the above technical solution are:

[0083] When the water receiving plate 22 moves to a preset height with the spray water collecting box 21, the cleaning rod 27 passes through the filter holes on the filter hole plate 10 one by one, cleans the particulate matter in the filter holes, loosens them, and facilitates them to flow down with the spray water, while reducing the possibility of clogging of the filter hole plate 10; when the cleaning rod 27 passes through the filter holes, there is a gap between the two, which will not hinder the exhaust gas from flowing upward. Embodiment 6

[0084] like Figure 6-8 As shown, on the basis of the above-mentioned embodiment 1, a swirl mixing box 41 is arranged between the spray unit 3 and the activated carbon filler layer 4, and the swirl mixing box 41 includes a mixing chamber 42 located in the center and two air inlet chambers 43 located on both sides, the top end of the mixing chamber 42 is connected to the upper part of the shell 1, and the bottom end of the air inlet chamber 43 is connected to the swirl air inlet pipe 48, and the swirl air inlet pipe 48 is connected to the lower part of the shell 1.

[0085] The swirl mixing box 41 also includes:

[0086] A rotating shaft 44, the rotating shaft 44 is rotatably connected to the inner wall of the mixing chamber 42 and is arranged vertically;

[0087] The swirl blade 45 is spirally connected to the lower part of the rotating shaft 44 to form a swirl mixing zone at the lower part of the mixing chamber 42, which is used to swirl the airflow and the spray water and mix them evenly;

[0088] A stirring rod 46, which is evenly arranged on the upper part of the rotating shaft 44, forming a stirring and mixing zone on the upper part of the mixing chamber 42, and is used to disperse the airflow and the spray water;

[0089] The spiral guide vane 47 is connected to the stirring rod 46 and is used to guide the evenly mixed airflow and spray water to flow out at a preset angle.

[0090] The working principle and beneficial effects of the above technical solution are:

[0091] The swirl mixing box 41 is arranged above the spray unit 3. After being sprayed, the exhaust gas will be mixed with a part of the spray water. The exhaust gas carries the spray water and flows upward, enters the air inlet chamber 43 through the swirl air inlet pipe 48, and then enters the mixing chamber 42 from both sides. The airflow drives the swirl blade 45 to rotate, so that the rotating shaft 44 rotates, and the stirring rod 46 also rotates accordingly; when the swirl blade 45 rotates, the airflow and the spray water are evenly mixed under the action of the spiral blade, so that the airflow and the spray water are better contacted, so that the spray water can fully cool down and reduce dust on the airflow; the evenly mixed airflow and spray water flow to the mixing chamber 42, at this time, the air flow temperature has been sufficiently reduced, the stirring rod 46 collides with the air flow and the spray water, and knocks down the heavier water droplets in the air flow, so that the water droplets slide along the inner wall of the swirl mixing box 41 under the action of centrifugal force and gravity, and flow out through the drain port set at the bottom of the swirl mixing box 41; the separated air flow flows out from the top of the swirl mixing box 41 at a preset angle under the guidance of the spiral guide plate 47, so that the air flow and the activated carbon filling layer 4 are at a preset angle, which fully increases the contact area of ​​the air flow when it flows through the activated carbon filling layer 4, and improves the activated carbon purification effect.
