Description

Technical Field

[0001] This utility model belongs to the field of ammonia storage technology, specifically relating to an ammonia tank with a spray structure. Background Technology

[0002] Ammonia tanks are sealed containers used to store ammonia. In industrial production, ammonia often decomposes due to increased ambient temperature or prolonged storage time, resulting in the volatilization of ammonia gas. This not only reduces the effective concentration but may also cause safety risks and environmental pollution. Therefore, specialized ammonia tanks with spray structures are needed to improve safety.

[0003] Traditional ammonia tanks mostly use open-type ring spray for cooling. Although this can achieve the cooling effect, the liquid is easily contaminated by external dust, which can cause the nozzles to accumulate and clog. Uneven spray coverage can also lead to local overheating, making it difficult to meet the requirements of efficient and stable temperature control. Utility Model Content

[0004] In view of this, the present invention provides an ammonia tank with a spray structure, which can avoid liquid pollution, blockage and evaporation loss that may be caused by open spraying through a closed annular rotating spray system. Under the vertical array layout of the spray heads and the rotating atomization effect, the tank body can be rapidly and uniformly cooled down.

[0005] To solve the above-mentioned technical problems, this utility model provides an ammonia tank with a spray structure, including a storage tank and a spray mechanism disposed outside it. The spray mechanism includes an annular cover disposed outside the storage tank. A feed pipe is provided in the liquid inlet at the upper end of the annular cover, and a discharge pipe is provided in the liquid outlet at the lower end of the annular cover. A rotating diversion box is rotatably connected to the upper end of the inner cavity of the annular cover. The rotating diversion box is connected to the feed pipe. Spray pipes are provided in several liquid outlet holes at the lower end of the rotating diversion box. Spray heads are provided in vertically evenly arranged discharge holes on the outer arc surface of the spray pipes. The spray ends of the spray heads are all facing the storage tank. The annular cover is also provided with a drive component for driving the rotating diversion box to rotate. That is, through the closed annular rotating spray system, liquid contamination, blockage and evaporation loss that may be caused by open spraying are avoided. Under the vertical array layout of the spray heads and the rotating atomization effect, rapid and uniform cooling of the entire surface of the tank is achieved. The inclined design of the bottom of the storage tank ensures that the liquid flows back and circulates efficiently along the lowest point discharge pipe.

[0006] The drive assembly includes a bevel gear ring located at the lower end of the rotating splitter box. A bevel gear is rotatably connected to the inner arc surface of the annular cover near the bevel gear ring. The bevel gear meshes with the bevel gear ring, thus achieving rapid transmission.

[0007] The drive assembly also includes a motor disposed on the outer arc surface of the annular cover. The output shaft of the motor is fixedly connected to a bevel gear, which provides a drive source for the annular cover.

[0008] It also includes heat exchange components, which include heat exchange tubes installed inside the storage tank. The inlet and outlet ends of the heat exchange tubes penetrate the tank wall and are connected to the corresponding feed pipe and discharge pipe, thus playing the role of internal cooling.

[0009] The heat exchange tubes are spiral-shaped, which increases the heat exchange area.

[0010] The inner arc surface of the annular cover is equipped with a protective cover. The upper end of the protective cover is rotatably connected to the lower end of the rotating diverter box. Both the bevel gear and the bevel gear ring are located inside the protective cover, which provides safety protection for the internal mechanism.

[0011] The bottom of the storage tank's inner cavity is inclined, and the discharge pipe is located at the very bottom of the storage tank's inner cavity, which serves to quickly drain the liquid.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Connect the circulation inlet and outlet of the external cooling water network to the corresponding feed pipe and discharge pipe respectively. The storage tank introduces ammonia water into the rotating distribution box through the feed pipe on the external annular cover. At the same time, the drive component drives the rotating distribution box to rotate, causing the spray pipe connected below it to move accordingly. The spray heads, which are vertically and evenly distributed on the outer arc surface of the spray pipe, rotate synchronously and spray. The spray ends are directed towards the storage tank to achieve circumferential full-coverage atomization cooling. The closed annular rotating spray system avoids liquid contamination, blockage and evaporation loss that may be caused by open spraying. The vertical array layout of the spray heads and the rotating atomization effect achieve rapid and uniform cooling of the entire surface of the tank. The inclined design at the bottom of the storage tank ensures that the liquid flows back and circulates efficiently along the lowest point discharge pipe.

[0014] 2. When the motor starts, its output shaft rotates, driving the bevel gear to rotate synchronously. When the bevel gear rotates, it drives the rotating distributor box to rotate through the bevel gear ring that meshes with it, thus achieving a rapid driving effect.

[0015] 3. The spiral heat exchange tubes are used to form a medium circulation, which accelerates heat exchange and enhances cooling efficiency. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides an ammonia tank with a spray structure, such as Figure 1-4 As shown: It includes a storage tank 100 and a spraying mechanism disposed outside it. The spraying mechanism includes an annular cover 200 disposed outside the storage tank 100. The inlet of the upper end of the annular cover 200 is provided with a feed pipe 201, and the outlet of the lower end of the annular cover 200 is provided with a discharge pipe 202. The upper end of the inner cavity of the annular cover 200 is rotatably connected to a rotating diversion box 203, which is connected to the feed pipe 201. Several outlet holes at the lower end of the rotating diversion box 203 are provided with spray pipes 204. The outlet holes on the outer arc surface of the spray pipes 204 are vertically and evenly arranged with spray heads 205. The spraying ends of the spray heads 205 are all facing the storage tank 100. The annular cover 200 is also provided with a drive assembly for driving the rotating diversion box 203 to rotate. The bottom of the inner cavity of the storage tank 100 is inclined, and the discharge pipe 202 is located at the lowest end of the bottom of the inner cavity of the storage tank 100.

[0023] The circulation inlet and outlet of the external cooling water network are connected to the corresponding feed pipe 201 and discharge pipe 202, respectively. The storage tank 100 introduces ammonia water into the rotating distribution box 203 through the feed pipe 201 on the external annular cover 200. At the same time, the drive component drives the rotating distribution box 203 to rotate, causing the spray pipe 204 connected below it to move accordingly. The spray heads 205, which are vertically and evenly distributed on the outer arc surface of the spray pipe 204, rotate synchronously and spray. The spray head is directed towards the storage tank 100 to achieve circumferential full-coverage atomization cooling. The closed annular rotating spray system avoids liquid contamination, blockage and evaporation loss that may be caused by open spraying. The vertical array layout of the spray heads 205 and the rotating atomization effect achieve rapid and uniform cooling of the entire surface of the tank. The inclined design of the bottom of the storage tank 100 ensures that the liquid flows back and circulates efficiently along the lowest point discharge pipe 202.

[0024] like Figure 2-3 As shown, the drive assembly includes a bevel gear ring 300 disposed at the lower end of the rotating diverter box 203. A bevel gear 301 is rotatably connected to the inner arc surface of the annular cover 200 near the bevel gear ring 300. The bevel gear 301 meshes with the bevel gear ring 300. The drive assembly also includes a motor 302 disposed on the outer arc surface of the annular cover 200. The output shaft of the motor 302 is fixedly connected to the bevel gear 301.

[0025] When the motor 302 starts, its output shaft rotates and drives the bevel gear 301 to rotate synchronously. When the bevel gear 301 rotates, it drives the rotating distributor box 203 to rotate through the bevel gear ring 300 that meshes with it, thus achieving a rapid driving effect.

[0026] like Figure 2-4 As shown, it also includes a heat exchanger, which includes a heat exchange tube 400 disposed in the storage tank 100. The inlet and outlet ends of the heat exchange tube 400 penetrate the tank wall of the storage tank 100 and are connected to the corresponding feed pipe 201 and discharge pipe 202. The heat exchange tube 400 is spiral in shape.

[0027] At the same time, the spiral heat exchange tube 400 is used to form a medium circulation, which accelerates heat exchange and enhances cooling efficiency.

[0028] like Figure 2-3 As shown, the inner arc surface of the annular cover 200 is provided with a protective cover 500. The upper end of the protective cover 500 is rotatably connected to the lower end of the rotating diverter box 203. The bevel gear 301 and the bevel gear ring 300 are both located inside the protective cover 500. The protective cover 500 forms a sealed protection for the bevel gear 301 and the bevel gear ring 300 to prevent corrosion and the intrusion of external pollutants.

[0029] The working principle of the ammonia tank with a spray structure provided by this utility model is as follows: First, the circulation inlet and outlet of the external cooling water network are connected to the corresponding feed pipe 201 and discharge pipe 202, respectively. The storage tank 100 introduces ammonia into the rotating distribution box 203 through the feed pipe 201 on the external annular cover 200. At the same time, the motor 302 starts, and its output shaft rotates to drive the bevel gear 301 to rotate synchronously. When the bevel gear 301 rotates, it drives the rotating distribution box 203 to rotate through the bevel gear ring 300 meshing with it, so that the spray pipe 204 connected below it moves accordingly. The spray heads 205, which are vertically and evenly distributed on the outer arc surface of the spray pipe 204, rotate synchronously to spray. The system achieves circumferential full-coverage atomized cooling by directing the spray nozzles towards the storage tank 100. Simultaneously, the spiral heat exchange tubes 400 form a medium circulation, accelerating heat exchange. The closed-loop rotating spray system avoids liquid contamination, blockage, and evaporation losses that may occur with open spraying. The vertical array layout of the spray nozzles 205 and the rotating atomization effect achieve rapid and uniform cooling of the entire surface of the tank. At the same time, the heat exchange tubes 400 enhance the cooling efficiency. The inclined design at the bottom of the storage tank 100 ensures efficient backflow circulation of liquid along the lowest point discharge pipe 202. The protective cover 500 provides a sealed protection for the bevel gear 301 and bevel gear ring 300, preventing corrosion and the intrusion of external contaminants.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
