Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment, and more specifically, to environmental protection equipment for waste gas treatment. Background Technology

[0002] Chinese patent document CN221673881U, entitled "A Waste Gas Spray Tower Equipment for Waste Gas Treatment," discloses a spray equipment for waste gas treatment. It mainly features a dual-spray cylinder structure. Each spray cylinder contains a blower fan and spray heads. The blower fan draws the waste gas to be treated from the lower part of the spray cylinder and blows it upwards. A booster pump delivers spray liquid from a storage tank to the spray heads located at the top of the spray cylinder, where it is dispersed and sprayed down, causing the spray liquid and waste gas to mix and react, thereby purifying the waste gas. However, this structure uses spray heads to spray the spray liquid, and the spray liquid and waste gas in each spray cylinder only undergo one mixing process, making it difficult to achieve sufficient and effective mixing, resulting in low purification efficiency. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention provides an environmental protection device for waste gas treatment that achieves high purification efficiency through double mixing of spray liquid and waste gas flow.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] An environmental protection device for treating waste gas includes a spray cylinder assembly. The spray cylinder assembly includes a spray cylinder, a blower fan located inside and below the spray cylinder, and a spray component for spraying spray liquid from the inside and above of the spray cylinder. It also includes: a collection tank for collecting residual spray liquid sprayed by the spray component onto the inner wall of the spray cylinder, and converging and conveying the collected residual spray liquid to a liquid separator; and a liquid separator, fixedly connected to the upper part of the blower fan and coaxial with the blower fan, for uniformly discharging the residual spray liquid circumferentially.

[0006] Furthermore, the liquid-splitter includes a disc-shaped hollow cavity, multiple liquid outlet holes and liquid inlet holes. The multiple liquid outlet holes are evenly arranged on the circumference of the cavity and communicate with the interior of the cavity. The liquid inlet holes are located in the middle of the top of the cavity and communicate with the interior of the cavity.

[0007] Furthermore, the liquid-splitting device includes multiple liquid-splitting plates, which are disposed on the bottom surface of the cavity and are evenly arranged around the axis of the cavity. The outer ends of the liquid-splitting plates extend to near the circumferential wall of the cavity, and the inner ends of the liquid-splitting plates extend to near the axis of the cavity and are offset from the axis.

[0008] Furthermore, a conical protrusion is provided in the middle of the inner bottom surface of the cavity, the inner end of the liquid-slinging plate is in contact with the conical protrusion, and a gap is left between the top surface of the liquid-slinging plate and the inner top surface of the cavity.

[0009] Furthermore, it also includes a disperser, which is used to passively impact the residual spray liquid ejected from the sprayer to disperse the residual spray liquid.

[0010] Furthermore, the disperser includes a fixed ring and multiple rigid impact rods. The fixed ring is fixedly connected to the inner wall of the spray cylinder by multiple radially arranged connecting rods. The multiple impact rods are evenly arranged around the fixed ring and their upper ends are fixedly connected to the fixed ring. The lower ends of the impact rods extend downward to below the liquid outlet of the liquid separator.

[0011] Furthermore, the liquid collection tank includes an annular groove and a guide groove. The annular groove is fixedly connected to the inner wall of the spray cylinder. The upper end of the guide groove is fixedly connected to and communicates with the annular groove. The lower end of the guide groove extends downward at an angle to the liquid inlet of the liquid ejector.

[0012] Furthermore, the guide channel has multiple channels evenly arranged along the annular groove, and the lower ends of the multiple guide channels are all offset from the axis of the liquid slinger.

[0013] Furthermore, the spray cylinder assembly has two sets, wherein the air outlet of the first set of spray cylinder assemblies is connected to the air inlet of the second set of spray cylinder assemblies.

[0014] Furthermore, the spray assembly includes a liquid storage tank, a booster pump, and two sets of spray heads. The liquid storage tank is connected to the outlet of the first set of spray cylinder assemblies and the second set of spray cylinder assemblies. The two sets of spray heads are respectively located inside the spray cylinders of the first set of spray cylinder assemblies and the second set of spray cylinder assemblies. The inlet of the booster pump is connected to the liquid storage tank, and the outlet of the booster pump is connected to both sets of spray heads through a pipe. Each pipe leading to the two sets of spray heads is equipped with a switch valve.

[0015] In summary, the present invention offers the following advantages: A collection tank is installed inside the spray cylinder to collect residual spray liquid from the inner wall of the spray cylinder and direct it to a liquid separator. The liquid separator is fixedly connected to a blower fan and rotates synchronously with the blower fan. The residual spray liquid flowing into the liquid separator is subjected to centrifugal force and is evenly ejected circumferentially from the separator. During operation, the blower fan drives the exhaust gas flow into the spray cylinder. The exhaust gas passes first through the residual spray liquid ejected by the liquid separator and then through the spray liquid sprayed by the spray components, undergoing two mixing reactions, resulting in a higher degree of mixing and purification efficiency.

[0025] Reference Figures 1 to 3 An environmental protection device for treating waste gas includes a spray cylinder assembly 1, which includes a spray cylinder 2, a blower fan 3 located inside and below the spray cylinder 2, and a spray assembly for spraying spray liquid from the inside and above of the spray cylinder 2. It also includes a collection tank 4 for collecting residual spray liquid sprayed by the spray assembly onto the inner wall of the spray cylinder 2, and converging and conveying the collected residual spray liquid to a liquid separator 6; the liquid separator 6 is fixedly connected to the upper part of the blower fan 3 and coaxial with the blower fan 3, and is used to evenly throw the residual spray liquid out circumferentially.

[0026] Preferably, this waste gas treatment environmental protection equipment adopts a two-stage treatment method. For example... Figure 1 As shown, the spray cylinder assembly 1 has two sets, with the air outlet of the first set of spray cylinder assembly 1 connected to the air inlet of the second set of spray cylinder assembly 1. These two sets of spray cylinder assemblies 1 can be different in size, as long as their overall structure is the same. The exhaust gas is purified by the first set of spray cylinder assembly 1 and then by the second set of spray cylinder assembly 1, thus improving the purification level.

[0027] In one embodiment, reference is made to Figure 1 The spray assembly includes a liquid storage tank 51, a booster pump 52, and two sets of spray heads 53. The liquid storage tank 51 is connected to the outlet of both the first and second sets of spray cylinder assemblies 1. The two sets of spray heads 53 are respectively located above the inside of the spray cylinders 2 of the first and second sets of spray cylinder assemblies 1. The inlet of the booster pump 52 is connected to the liquid storage tank 51, and the outlet of the booster pump 52 is connected to both sets of spray heads 53 via pipes. Each pipe leading to one set of spray heads 53 is equipped with a switch valve 54. Using a single booster pump 52 to simultaneously supply spray liquid to both first sets of spray cylinder assemblies 1 results in a simple structure. If one of the spray cylinder assemblies 1 is not in operation, simply closing the corresponding switch valve 54 is sufficient. In this case, the waste gas treatment environmental protection equipment operates in a single-stage treatment mode, suitable for treating waste gas with relatively mild pollution levels.

[0028] In one embodiment, reference is made to Figure 2 and Figure 3 The liquid separator 6 includes a disc-shaped hollow cavity 61, multiple liquid outlet holes 62, and a liquid inlet hole 63. The multiple liquid outlet holes 62 are evenly arranged on the circumference of the cavity 61 and communicate with the interior of the cavity 61. The liquid inlet hole 63 is located in the middle of the top of the cavity 61 and communicates with the interior of the cavity 61. In use, the cavity 61 is fixedly connected to the blower fan 3. After the residual spray liquid flows into the cavity 61, it is dispersed and thrown out from the multiple liquid outlet holes 62 on the circumference of the cavity 61 under centrifugal force. It is further dispersed under the wind force of the blower fan 3, which facilitates mixing with the exhaust gas.

[0029] In one embodiment, reference is made to Figure 3 The liquid-splitter 6 includes multiple liquid-splitting plates 64, which are disposed on the bottom surface of the cavity 61 and evenly arranged around the axis of the cavity 61. The outer ends of the liquid-splitting plates 64 extend to near the circumferential wall of the cavity 61, and the inner ends of the liquid-splitting plates 64 extend to near the axis of the cavity 61 but are offset from the axis. By setting the liquid-splitting plates 64, the rotational flow of residual spray liquid in the cavity 61 can be accelerated, and the liquid can be ejected more quickly.

[0030] In one embodiment, reference is made to Figure 3The inner bottom surface of the cavity 61 is provided with a conical protrusion 65 in the middle. The inner end of the liquid-throwing plate 64 fits against the conical protrusion 65. The conical protrusion 65 allows the residual spray liquid to flow quickly to the circumference of the cavity 61 when it flows in, avoiding accumulation in the central area where centrifugal force is weak. In addition, there is a gap between the top surface of the liquid-throwing plate 64 and the inner top surface of the cavity 61. When a large amount of residual spray liquid flows in and fills a certain area, it can pass over the liquid-throwing plate 64 through this gap and flow to other positions behind in the direction of rotation, making the residual spray liquid more evenly distributed within the cavity 61.

[0031] In one embodiment, reference is made to Figure 2 The collection tank 4 of this waste gas treatment environmental protection equipment includes an annular groove 41 and a guide groove 42. The annular groove 41 is fixedly connected to the inner wall of the spray cylinder 2. The upper end of the guide groove 42 is fixedly connected to and communicates with the annular groove 41, and the lower end of the guide groove 42 extends downward at an inlet 63 of the liquid separator 6. In use, the residual spray liquid on the inner wall of the spray cylinder 2 flows into the annular groove 41, and then flows through the guide groove 42 to the inlet 63 of the liquid separator 6. Preferably, there are multiple guide grooves 42, which are evenly arranged along the annular groove 41 to improve the uniformity of the flow to the liquid separator 6. The number of guide grooves 42 is preferably three or four, which can be set according to actual needs. In addition, the lower ends of the multiple guide grooves 42 are all offset from the axis of the liquid separator 6 to avoid the residual spray liquid from the multiple guide grooves 42 colliding with each other at the axis and reducing the flow rate. Due to the staggered structure, when the residual spray liquid in the guide channel 42 flows out, it can flow more directly to the circumferential wall of the cavity 61, increasing the speed at which it is thrown out from the outlet hole 62.

[0032] In one embodiment, the waste gas treatment environmental protection equipment further includes a disperser 7, used to passively impact the residual spray liquid ejected from the liquid separator 6, thereby dispersing the residual spray liquid. Specifically, refer to... Figure 2 The disperser 7 includes a fixed ring 71 and multiple rigid impact rods 72. The fixed ring 71 is fixedly connected to the inner wall of the spray cylinder 2 via multiple radially arranged connecting rods. The multiple impact rods 72 are evenly arranged circumferentially along the fixed ring 71 and their upper ends are fixedly connected to the fixed ring 71. The lower ends of the impact rods 72 extend downwards to below the liquid outlet 62 of the liquid separator 6. The impact rods 72 are made of a highly rigid material, such as stainless steel, and their lower ends can disperse the residual spray liquid when impacted by it. In addition, the high rigidity of the impact rods 72 also makes it easier to generate high-frequency vibrations, which is beneficial to further disperse the residual spray liquid, improve the dispersion degree, and make the residual spray liquid in the exhaust gas mix and react better.

[0033] The above embodiments are merely explanations of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
