Description

Technical Field

[0001] The present application relates to the technical field of synthetic ammonia, and in particular to a synthetic ammonia boiler feed water system. Background Art

[0002] When processing and producing synthetic ammonia, a cascade heat recovery system is generally used to recycle the waste heat generated in the synthetic ammonia process. However, the existing water supply system has the same water supply temperature when supplying water to the cascade heat recovery system and the boiler, which cannot meet the water supply demand of the cascade heat recovery. The patent with announcement number CN219433231U discloses a synthetic ammonia boiler water supply system, which can cooperate with the cascade heat recovery system when supplying water, and use the cascade water supply to improve the recovery efficiency of the cascade heat recovery system. However, the above patent uses solenoid valves to control the conduction state between adjacent bins, which increases the complexity of the overall control. To this end, the inventor proposed a synthetic ammonia boiler water supply system. Utility Model Content

[0035] Example 1

[0036] See also Figure 1-Figure 3 This embodiment provides a synthetic ammonia boiler water supply system to solve the problem of complex conduction control system between adjacent silos in the existing cascade water supply system.

[0037] In this embodiment, the synthetic ammonia boiler feed water system includes a plurality of bins 20 arranged in sequence from top to bottom inside the tower body 10, the bins 20 are connected to the corresponding cascade heat recovery system, and a conduction component 30 is provided between adjacent bins 20, the conduction component 30 includes a floating body 31, a connecting rod 32, a head 34 and a positioning sleeve 33, the connecting rod 32 is fixed between the floating body 31 and the positioning sleeve 33, the head 34 is arranged inside the positioning sleeve 33, and the positioning sleeve 33 is sleeved on the outside of the connecting pipe 21 at the bottom of the bin 20, and the lifting and lowering of the floating body 31 can drive the head 34 to move inside the connecting pipe 21.

[0038] In this embodiment, the floating body 31 follows the rise and fall of the liquid level, so that the head 34 can move inside the connecting pipe 21 following the change of the liquid level, thereby realizing the use of the liquid level to control the conduction state of the adjacent bin bodies 20, simplifying the control system, and having the advantage of easy operation.

[0039] It should be noted that the tower body 10 is constructed as a whole in a cylindrical shape. Three bin bodies 20 are arranged in sequence from top to bottom inside the tower body 10, and the three bin bodies 20 are coaxially arranged with the tower body 10. The two upper bin bodies 20 have a conical bottom plate, and the connecting pipe 21 is arranged on the bottom plate and coaxially arranged with the bin body 20. The connecting pipe 21 extends downward into the interior of another bin body 20 located below it.

[0040] It should also be noted that the two upper silos 20 are both provided with a water supply pipe 24 and a water return pipe 23. The water supply pipe 24 is located at the bottom of the silo 20, and the water return pipe 23 is located at the top of the silo 20. Only the water supply pipe 24 is provided on the lowest silo 20. At the same time, a water pump 25 for supplying water to the lowest silo 20 is provided inside the tower body 10. When supplying water, the low-temperature water inside the lowest silo 20 flows into the water inlet of the secondary heat recovery system through the water supply pipe 24 of the lowest silo 20. The medium-temperature water in the middle silo 20 flows through the water supply pipe 24 of the middle silo 20 into the water inlet pipe of the first heat recovery system, and then flows from the water supply pipe of the first heat recovery system into the return pipe 23 of the uppermost silo 20; the high-temperature water in the uppermost silo 20 flows through the water supply pipe 24 into the water inlet pipe of the first synthetic ammonia boiler, thereby realizing cascade water supply and cooperating with the cascade heat recovery system for heat recovery.

[0041] In this embodiment, the floating body 31 is constructed as a whole in a disc shape, and the bottom and top of the floating body 31 are both constructed as conical surfaces. The connecting rod 32 is fixed between the floating body 31 and the positioning sleeve 33, and the floating body 31, the connecting rod 32 and the positioning sleeve 33 are kept coaxially arranged. The positioning sleeve 33 can be slidably mounted on the outside of the connecting tube 31 along the axial direction. A limiting groove 22 extending along the axial direction is opened on the outer wall of the connecting tube 21, and a limiting column 36 arranged along the radial direction is screwed on the positioning sleeve 33. The inner end of the limiting column 36 can be slidably engaged with the inside of the limiting groove 22, so that the positioning sleeve 33 can only slide along the axial direction of the connecting tube 21.

[0042] It should be understood that the sliding engagement between the limiting groove 22 and the limiting column 36 can limit the moving distance of the positioning sleeve 33 on the connecting pipe 21 and ensure that the positioning sleeve 33 does not separate from the connecting pipe 21 .

[0043] In addition, the top of the connecting rod 32 extends into the interior of the positioning sleeve 33, and a connecting plate 35 is fixed between the connecting rod 32 and the positioning sleeve 33. The connecting plate 35 is arranged along the radial direction of the positioning sleeve 33, and the connecting plate 35 is evenly distributed along the circumference of the positioning sleeve 33. The head 34 is fixed to the top of the connecting rod 32. When the head 34 is moved into the interior of the connecting pipe 21, the head 34 and the connecting pipe 31 can be sealed and connected.

[0044] During use, when the liquid level inside the warehouse body 20 drops, the floating body 31 will drop synchronously with the liquid level, and the overall gravity of the conductive component 30 will overcome the friction between the head 34 and the connecting tube 21, causing the head 34 to move toward the outside of the connecting tube 21 until the head 34 is separated from the connecting tube 21. At this time, the two adjacent warehouse bodies 20 are connected through the connecting tube 21. Similarly, when the liquid level inside the warehouse body 20 rises, the head 34 will be moved into the connecting tube 21 again under the push of the floating body 31, thereby achieving the closure of the connecting tube 21.

[0045] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
