Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a waste gas treatment device in the process of hazardous waste disposal. Background Technology

[0002] Waste gas treatment is the process of purifying industrial pollutants through physical and chemical methods to meet environmental standards. It primarily targets harmful substances such as particulate matter, organic waste gas, and acidic / alkaline waste gas generated in industrial sites. The core objective is to reduce harm to the environment and human health. Common waste gas treatment equipment includes waste gas spray dust suppression towers, which can treat incoming waste gas through spray-based dust suppression.

[0003] However, existing exhaust gas spray dust suppression towers have the following problems during use: These towers use spray components installed inside the tower to treat suspended solids in the exhaust gas, but the effectiveness of existing spray components in water atomization is generally fixed, making it impossible to adjust the degree of water atomization according to actual usage needs, which may affect the dust suppression effect. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a waste gas treatment device in the process of hazardous waste disposal. It solves the problem that the existing spray dust suppression tower uses spray components installed in the tower body to spray and suppress suspended matter in the waste gas. However, the effect of water atomization spraying of the existing spray components is generally fixed and cannot be adjusted according to the actual spraying needs, which may affect the effect of dust suppression of waste gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device for hazardous waste disposal, comprising a tower body, an inlet pipe, an exhaust pipe, a water conveying mechanism, and an adjustable spray assembly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a waste gas treatment device for hazardous waste disposal, including a tower body 1, an air inlet pipe 2, an exhaust pipe 3, a water conveying mechanism, and an adjustable spray assembly. The tower body 1 has a dust-suppressing inner cavity 4. The air inlet pipe 2 is installed at the lower left corner of the tower body 1, and the exhaust pipe 3 is installed at the top of the tower body 1. The water conveying mechanism includes a water storage tank 5, a water pump 6, a water conveying pipe, and branch pipes 7. The water storage tank 5 is located on one side of the tower body 1. The water pump 6 is installed inside the water storage tank 5. The inlet end of the water pump 6 is connected to the water storage tank 5 via a pipe, and the outlet end is connected to three sets of branch pipes 7 via a water conveying pipe. The three sets of branch pipes 7 are evenly distributed from top to bottom on one side of the tower body 1. The inner end of each branch pipe 7 is connected to the adjustable spray assembly. The adjustable spray assembly includes a rigid guide pipe 8, a horizontal pipe 9, a spray ring 10, a nozzle 11, and a regulator 12. One end of the drainage pipe 8 is connected to the branch pipe 7 and the other end is connected to the horizontal pipe 9. The horizontal pipe 9 is installed inside the spray ring 10. The spray ring 10 has a liquid storage channel 13 inside. The nozzles 11 are divided into several groups and are evenly installed at the bottom of the spray ring 10. The regulator 12 is installed at the bottom of the spray ring 10 and is used in conjunction with the nozzles 11. The regulator 12 includes a drive motor 14, a drive gear 15, a driven ring 16 and an atomizing sleeve 17. The drive motor 14 is installed below the spray ring 10 and its power output end is connected to the drive gear 15. The inner and outer rings of the driven ring 16 are both machined with several sets of retaining teeth 18. The drive gear 15 meshes with the retaining teeth 18 of the inner ring of the driven ring 16. The atomizing sleeve 17 is installed at the lower end of the nozzle 11 and is used in conjunction with the driven ring 16. The retaining teeth of the outer ring of the driven ring 16 mesh with the retaining teeth on the disc 22.

[0021] Further improvements, such as Figure 1 As shown, the water storage tank 5 has an overall arc-shaped structure and is attached to one side of the tower body 1.

[0022] Further improvements, such as Figure 4 As shown, the atomizing sleeve 17 includes an outer sleeve 19 and an atomizing disc 20 installed at the lower end of the outer sleeve 19. The upper end of the outer sleeve 19 is connected to the water outlet of the nozzle 11, and the lower end is eccentrically provided with an atomizing port 21. The atomizing disc 20 is rotatably installed at the bottom of the outer sleeve 19. The water sprayed from the nozzle 11 can be atomized a second time through the atomizing disc 20.

[0023] Further improvements, such as Figure 4 As shown, the upper diameter of the outer sleeve 19 is smaller than the lower diameter, and the upper diameter of the outer sleeve 19 is larger than the lower diameter of the nozzle 11. This design facilitates the introduction of water into the nozzle 11.

[0024] Specifically, the atomizing disc 20 includes a disc body 22 and four sets of dividing strips installed on the disc body 22. The outer periphery of the disc body 22 is also machined with retaining teeth 18. The four sets of dividing strips divide the disc body 22 into four atomizing zones 23. Each atomizing zone 23 has several sets of atomizing holes 24. The diameter of the atomizing holes 24 on the four sets of atomizing zones 23 increases counterclockwise. The atomizing zone 23 has a fan-shaped structure and its width is greater than the diameter of the atomizing port 21. By dividing the atomizing disc 20 into zones, and the diameter of the atomizing holes 21 in each atomizing zone 23 is different, the atomizing zone 23 of the corresponding specification can be rotated to the atomizing port 21 at the lower end of the outer sleeve 19 according to actual needs, and the water passing through can be further atomized.

[0025] In use: When it is necessary to spray dust suppression on exhaust gas, the exhaust gas pipeline is connected to the inlet pipe 2 and the exhaust gas is introduced into the tower body 1 through the inlet pipe 2. At the same time, the water pump 6 draws water from the water storage tank 5 and flows it through the water supply pipe, branch pipe 7, rigid diversion pipe 8 and horizontal pipe 9 to the spray ring 10. The water in the spray ring 10 is guided outward through the nozzle 11 and enters the atomizing sleeve 17. The water flow is further atomized through the atomizing holes 21 of the atomizing zone 23 to improve the spraying effect. In addition, during use, the atomization degree can be adjusted according to the actual use needs. The drive motor 14 drives the drive gear 15 to rotate. During the rotation of the drive gear 15, the driven ring 16 rotates. The driven ring 16 acts on the disc body 22 and drives the disc body 22 to rotate synchronously, rotating the atomizing zone 23 of the corresponding specification to the atomizing port 21 at the lower end of the outer sleeve 19, thereby achieving the purpose of atomization adjustment.
