[0024] See also Figure 1-2 The utility model provides an embodiment: a demister spray tower, comprising a spray tower body 1, an air inlet is fixedly installed on the outer wall of the back of the spray tower body 1, the air inlet can be used to inject waste gas, and an exhaust port is arranged at the top of the spray tower body 1, and the exhaust port can discharge the waste gas after spray purification;

[0025] An internal packing area 8 is arranged at the center of the spray tower body 1. The packing material of the internal packing area 8 is a saddle ring 10. Since the arc saddle packing of the saddle ring 10 is easy to overlap and hang in the packing tower, it is transformed into a rectangular saddle packing with two asymmetric sides and unequal sizes. Therefore, the porosity, uniformity, effective surface and liquid distribution performance of the packing bed are improved, thereby effectively improving the waste gas treatment quality of the spray;

[0026] Since the larger the surface area of ​​the filler is, the larger the area in contact with the reactants is, the reaction rate will increase accordingly, which can effectively improve the quality and efficiency of the waste gas treatment by spraying, improve the quality of the waste gas emission standards, and have a better use effect;

[0027] A demister 3 is fixedly installed inside the top of the spray tower body 1. The demister 3 is a device structure composed of a high-efficiency filter and a radiator. It can reduce the humidity in the air to achieve the demisting function. This is a mature technical product on the existing market, and this manual will not be described in detail.

[0028] A spray pipe 6 is fixedly installed between the demister 3 and the internal filling area, and a plurality of evenly distributed spray heads 7 are fixedly installed below the spray pipe 6. A cavity is provided below the internal filling area 8 and inside the spray tower body 1, and the cavity forms a circulating water area 9.

[0029] In this embodiment, a circulating water tank 2 is fixedly mounted on the outer wall of one side of the spray tower body 1 , and liquid for spraying can be stored inside the circulating water tank 2 . A circulating water pump 4 is fixedly mounted on one side of the bottom end of the circulating water tank 2 .

[0030] Furthermore, the water outlet of the circulating water pump 6 is fixedly connected to the circulating pipe 5, and the tail end of the circulating pipe 5 is fixedly connected to the spray pipe 6;

[0031] Through the operation of the circulating water pump 6, the liquid in the circulating water tank 2 can be transported to the inside of the spray pipe 6, and finally sprayed out through the provided spray head 7, thereby completing the spraying work of the smoke.

[0032] In this embodiment, in order to ensure the normal liquid circulation effect, the bottom end of the circulating water tank 2 is interconnected with the circulating water area 9 through a through port;

[0033] The liquid flowing down through the inner filling area 8 can enter the circulating water area 9, and then enter the circulating water tank 2 through the circulating water area 9 for recycling, reducing resource waste, improving recycling efficiency, and thus effectively reducing the cost of spraying treatment.

[0034] In this embodiment, the saddle ring 10 is a PP saddle ring, and three groups of through holes 1001 are opened on the central upper surface of the saddle ring 10, and a serrated edge 1002 is provided on the outer surface of the saddle ring 10;

[0035] By providing a serrated edge 1002 on the saddle ring 10, the saddle ring 10 is improved into a shell-shaped arc surface with a serrated edge, and a through hole 1001 is added, so that the inner and outer surfaces of the filler are connected, the free passage of the fluid is increased, the flow channel is more unobstructed, and the gathering points between the filler units are increased, which is beneficial to liquid distribution and surface renewal;

[0036] Therefore, the saddle ring 10 packing of the utility model has higher processing capacity, lower pressure drop and improved mass transfer performance.

[0037] Working principle: When the waste gas needs to be sprayed and purified, the waste gas can be injected through the set air inlet, and the injected waste gas enters the inside of the spray tower body 1. At this time, the set circulating water pump 4 can work, and the circulating water pump 4 transports the spray liquid in the circulating water tank 2 to the inside of the spray pipe 6 through the circulating pipe 5, and sprays it out through the spray head 7 set below the spray pipe 6;

[0038] In this way, the injected waste gas can be sprayed and purified. During the spraying process, a certain weight of water film will be attached to the outside of the small floating impurities in the waste gas, so that they can fall freely by increasing gravity, thereby achieving the purpose of purifying and removing impurities in the waste gas;

[0039] By arranging a demister 3 inside the spray tower body 1, it can reduce the humidity in the air, thereby realizing the demisting function, and having a better demisting effect;

[0040] The purified waste gas is discharged through the exhaust port, and the small impurities that fall down will enter the internal packing area 8. The packing material of the internal packing area 8 is a saddle ring 10. Since the arc saddle packing of the saddle ring 10 is easy to overlap and hang in the spray tower body 1, it is transformed into a rectangular saddle packing with asymmetric sides and unequal sizes. Therefore, the porosity, uniformity, effective surface and liquid distribution performance of the packing bed are improved, thereby effectively improving the waste gas treatment quality of the spray;

[0041] By providing a serrated edge 1002 on the saddle ring 10, the saddle ring 10 is improved into a shell-shaped arc surface with a serrated edge, and a through hole 1001 is added, so that the inner and outer surfaces of the filler are connected, the free passage of the fluid is increased, the flow channel is more unobstructed, and the gathering points between the filler units are increased, which is beneficial to liquid distribution and surface renewal;

[0042] Therefore, the saddle ring 10 packing of the utility model has higher processing capacity, lower pressure drop and improved mass transfer performance;

[0043] Since the larger the surface area of ​​the filler is, the larger the area in contact with the reactants is, the reaction rate will increase accordingly, which can effectively improve the quality and efficiency of the waste gas treatment by spraying, improve the quality of the waste gas emission standards, and have a better use effect;

[0044] The liquid flowing down through the inner filling area 8 can enter the circulating water area 9, and then enter the circulating water tank 2 through the circulating water area 9 for recycling, reducing resource waste, improving recycling efficiency, and thus effectively reducing the cost of spraying treatment.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
