Description

Technical Field

[0001] This utility model belongs to the field of cooling tower technology, and in particular relates to a spray device for a cooling tower in a pyrite-to-acid system. Background Technology

[0002] In the process flow of sulfuric acid production from pyrite, the cooling tower, as a key piece of equipment, plays a crucial role in cooling high-temperature gases or liquids. Traditional cooling tower spray systems mostly employ fixed spray structures, using fixed nozzles for spraying. However, this structure has several shortcomings in practical applications:

[0003] On the one hand, fixed spray structures are difficult to achieve uniform coverage of the spray area, resulting in some areas being over-sprayed while others are under-sprayed, which affects the cooling effect and efficiency.

[0004] On the other hand, traditional spray devices lack flexibility in meeting different cooling requirements. When spray cooling of gas is required, specific filler material needs to be filled to increase the gas-liquid contact area; while when spray cooling of liquid is required, different spraying methods and structures are needed. However, traditional spray devices often cannot meet both requirements at the same time, resulting in low equipment utilization and increased production costs. Utility Model Content

[0005] The purpose of this invention is to provide a spraying device for cooling towers in pyrite-to-acid production systems. This device utilizes a water-driven spray pipe to rotate horizontally, forming an adaptive rotating spraying mechanism with a circular trajectory. This ensures uniform and stable spraying, achieving full coverage of the spraying area and significantly improving cooling efficiency. By adopting a modular installation design and using either a first or second mounting cylinder, it can adapt to both gas and liquid operating conditions, enhancing equipment versatility. The spraying system is autonomously driven by the fluid kinetic energy of the inlet pipe, eliminating the need for an external power source. This optimizes energy consumption while reducing maintenance costs. The synergy of these three elements achieves efficient cooling and resource-intensive operation, solving existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A spray device for a cooling tower in a pyrite-to-acid production system includes:

[0008] At least one spray unit, the spray unit including a spray cylinder and a spray assembly disposed inside the spray cylinder; the spray assembly including a cross pipe, a plurality of spray pipes evenly distributed at the bottom of the cross pipe, a rotating frame and a fixed pipe; the rotating frame is rotatably installed inside the spray cylinder, and the fixed pipe passes through the center of the rotating frame; the cross pipe is connected to the fixed pipe through a first connecting pipe, and the upper end of the fixed pipe is connected to a rotary joint.

[0009] The driving mechanism includes an inlet pipe connected to an external water source, a fixed box, a rotating shaft, and a first gear and a second gear that mesh and drive each other. The fixed box connects the inlet pipe to the rotary joint, the rotating shaft passes through the fixed box and is fixed to the second gear, and the first gear is fixedly sleeved on the outer wall of the fixed pipe. Water flows through the inlet pipe to drive the rotating shaft to rotate, and the gear meshing drives the spray pipe to rotate horizontally to form a ring spray.

[0010] At least one mounting part is provided, which is located close to the bottom of the spray unit, for setting up corresponding components according to the needs of gas and liquid spraying.

[0011] Optionally, the mounting part can be a first mounting cylinder or a second mounting cylinder; the first mounting cylinder is provided with a support mesh to support the filling layer, and the second mounting cylinder is provided with an annular pipe to transport liquid.

[0012] Optionally, the fixing box is fixed inside the spray cylinder by a bracket, and the fixing box is provided with a drive wheel driven by water flow. The drive wheel is sleeved on the outer wall of the rotating shaft and in contact with the water flow.

[0013] Optionally, a feeding port is provided on one side of the spray section, and the feeding port is hinged to a movable door to place the filling layer material into the spray cylinder.

[0014] Optionally, the first mounting cylinder is connected to the bottom flange of the spray section, and the support mesh is a stainless steel mesh structure with a pore size smaller than the particle size of the filling layer material.

[0015] Optionally, the two ends of the annular pipe of the second mounting cylinder extend to the outer wall of the cylinder body, and the inner wall of the annular pipe is provided with spiral guide vanes to enhance liquid turbulence.

[0018] Optionally, the fixed part of the rotary joint is sealed and fixedly connected to one end of the second connecting pipe, and its rotating part is sealed and fixedly connected to one end of the first connecting pipe.

[0019] The embodiments of this utility model have the following beneficial effects:

[0020] In this invention, multiple spray pipes are horizontally rotated under the drive of water flow, so that the spray liquid forms a uniform spray in a circular trajectory within the spray area. This design ensures full coverage spraying inside the spray section and the connecting cavity below it, greatly improving the uniformity and stability of the spray, thereby enhancing the cooling effect and efficiency.

[0021] In this invention, by providing a flexibly replaceable mounting section, including a first mounting cylinder and a second mounting cylinder, the appropriate structure can be selected for assembly according to different cooling requirements.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0036] Example 1: Please refer to Figure 1-6 As shown, this embodiment provides a spraying device, mainly including a spraying section 1, an air inlet cylinder 3, a water storage tank 4, a top cover 5, and an installation section. Through the coordinated operation of each part, spraying and cooling treatment of the gas in the pyrite-to-acid system is achieved.

[0037] In this embodiment, the spray section 1 is the core part of the device, and at least one spray section 1 is provided. Each spray section 1 includes a spray cylinder 6 and a spray assembly. The spray assembly is disposed inside the spray cylinder 6 and consists of a cross pipe 12 and multiple spray pipes 14. The multiple spray pipes 14 are evenly arranged at the bottom of the cross pipe 12 and are fixedly connected to the cross pipe 12. The main function of the spray assembly is to provide spray to the inside of the spray section 1 and the connecting cavity below it, ensuring that the gas can fully contact the spray liquid to achieve cooling and purification effects.

[0038] In this embodiment, the spray assembly further includes a rotating frame 9 rotatably mounted inside the spray cylinder 6. A fixed pipe 11 is fixedly inserted through the rotating frame 9, and the fixed pipe 11 is located at the center of the rotating frame 9. A cross pipe 12 is located below the rotating frame 9, and a first connecting pipe 13 is fixedly installed on its top, with the top end of the first connecting pipe 13 fixedly penetrating the fixed pipe 11. A rotary joint 16 is provided above the fixed pipe 11, and the top end of the first connecting pipe 13 is fixedly connected to one end of the rotating part of the rotary joint 16.

[0039] Furthermore, in this embodiment, the spray assembly also includes a water inlet pipe 10 that is fixedly inserted through one side of the spray cylinder 6, and the water inlet pipe 10 is connected to an external water supply assembly. A fixing box 17 is fixedly connected to the other end of the water inlet pipe 10, and the fixing box 17 is fixedly installed inside the spray cylinder 6 by a bracket. A rotating shaft 18 rotatably passes through the inside of the fixing box 17, and a drive wheel 19 is rotatably sleeved on the outer wall of the rotating shaft 18, located inside the fixing box 17. A second connecting pipe 21 is fixedly installed at the other end of the fixing box 17, and the other end of the second connecting pipe 21 is fixedly connected to one end of the fixing part of the rotary joint 16. A second gear 20 is fixedly installed at the bottom end of the rotating shaft 18, and a first gear 15 is fixedly sleeved on the outer wall of the fixing pipe 11, with the second gear 20 meshing with the first gear 15.

[0040] During operation, the external water supply assembly delivers water to the fixed box 17 through the inlet pipe 10. As the water flows within the fixed box 17, it drives the drive wheel 19 to rotate, which in turn causes the rotating shaft 18 to rotate. Since the second gear 20 meshes with the first gear 15, the rotation of the rotating shaft 18 drives the fixed pipe 11 to rotate, thereby causing the cross pipe 12 and multiple spray pipes 14 to rotate horizontally. In this way, the multiple spray pipes 14 can evenly spray the spray liquid into the interior of the spray section 1 and the connecting cavity below it during rotation, ensuring uniform and stable spraying operation and improving the spraying effect.

[0041] In this embodiment, both the air inlet cylinder 3 and the water storage tank 4 are located below the spray section 1. The air inlet cylinder 3 is fixedly installed on the top of the water storage tank 4 and is connected to the water storage tank 4. The main function of the air inlet cylinder 3 is to allow gas to enter, introducing the gas to be cooled and purified into the spray device. The water storage tank 4 is used to collect the waste liquid after spraying, preventing the waste liquid from being discharged indiscriminately and causing environmental pollution.

[0042] In this embodiment, the top cover 5 is located above the spray section 1, and an air vent is provided on the top of the top cover 5. The hot air after spraying will be discharged from the equipment through the air vent, realizing the discharge of hot air from the equipment and maintaining the pressure balance inside the device.

[0043] In this embodiment, the mounting part is close to the lower part of the spraying part 1, and is used to set up corresponding components according to the needs of gas and liquid spraying. There are two forms of mounting part, namely a first mounting cylinder 2 and a second mounting cylinder 23.

[0044] This application can be used in the field of cooling tower technology, or in other fields applicable to this application.

[0045] Example 2: Reference Figure 1 , 2 6, 7, Improvements based on Example 1: A spray device for a cooling tower in a pyrite-to-acid system, which is applied to the field of cooling tower technology;

[0046] In this embodiment, the first mounting cylinder 2 is fixedly installed at the bottom of the adjacent spray section 1. A support net 22 is fixedly installed inside the first mounting cylinder 2, which is used to support and place the filler material to be used. In practical applications, suitable filler material, such as Pall rings or Raschig rings, can be added to the spray section 1 as needed.

[0047] In this embodiment, filler material can be placed into the spray section 1 through the feed port 7. The feed port 7 is located on one side of the spray section 1, and a movable door 8 is hinged to one end of the feed port 7. Opening the movable door 8 allows for convenient placement of the filler material. After the filler material is placed on the support net 22, it can make the gas distribution inside the first mounting cylinder 2 more uniform, thereby ensuring uniform spraying of the gas by the subsequent spray assembly and improving the spray cooling and purification effect.

[0048] In this embodiment, the second mounting cylinder 23 is also fixedly installed at the bottom of the adjacent spray section 1. A continuous annular pipe 24 is provided inside the second mounting cylinder 23, with both ends of the annular pipe 24 fixedly penetrating the outer wall of the second mounting cylinder 23. The annular pipe 24 is used to transport liquid and can cooperate with the spray assembly to complete the spraying and cooling of the liquid within the annular pipe 24.

[0049] In this embodiment, a drain pipe is fixedly installed on one side of the water storage tank 4 for discharging the waste liquid in the water storage tank 4; a filter screen is also provided on the top of the water storage tank 4 for filtering the waste liquid after use.

[0050] The usage process and working principle of this utility model technical solution are as follows:

[0051] When using the equipment, different structures can be selected for assembly depending on the substance to be cooled. When gas spraying is required, the user can install the first mounting cylinder 2 below the corresponding spray section 1. At this time, the user can fill the spray section 1 with suitable material through the feeding port 7. The support net 22 inside the first mounting cylinder 2 can support the corresponding filling material, ensuring good gas-liquid contact efficiency during subsequent spraying. When liquid spraying is required, the user can install the second mounting cylinder 23 below the corresponding spray section 1. At this time, the user can transport the liquid to be cooled through the annular pipe 24 and use an external pumping system. The high-temperature liquid will flow in the annular pipe 24 so that it can be sprayed and cooled in the equipment.

[0052] When the equipment is working, the external water supply component delivers pressurized water to the fixed box 17 through the water inlet pipe 10. The water flows through the second connecting pipe 21 into the fixed part of the rotary joint 16, and is injected into the cross pipe 12 through the first connecting pipe 13. Finally, multiple spray pipes 14 form atomized spray, so as to spray the space inside the spray section 1 and the space below it accordingly.

[0053] During the water flow drive process, the drive wheel 19 inside the fixed box 17 is driven by water pressure to rotate the rotating shaft 18. Through the meshing transmission of the second gear 20 and the first gear 15, the rotating frame 9 can be driven to rotate horizontally around the axis of the fixed pipe 11. This rotational action causes the spray pipe 14 to form a uniform spray in a circular trajectory inside the spray cylinder 6, achieving full coverage spraying of the inside of the spray section 1 and the connecting cavity below.

[0054] The cooled gas or hot steam after spraying will rise and then pass through the vent of the top cover 5 for collection or discharge. The spraying wastewater will flow down the inner wall of the spray cylinder 6, be filtered by the filter screen at the top of the water storage tank 4, and finally be collected in the water storage tank 4. It can then be discharged through the drain pipe.
