Description

Technical Field

[0001] This utility model relates to the field of cryogenic air separation technology, and more specifically, to a cryogenic air separation condensate device. Background Technology

[0002] Cryogenic oxygen production air separation systems are equipped with a circulating water tank for cooling and a fire-fighting water tank to ensure safe system operation and prevent fires and explosions. The cryogenic oxygen production process generates a large amount of condensate, including condensate from air compressor compression and condensate from the high-temperature regeneration of molecular sieves. This condensate is of excellent quality, reaching or approaching pure water standards, exceeding the system's water usage standards. Direct discharge would waste water resources, and direct discharge into the circulating water tank would affect the water temperature of the circulating water tank.

[0003] For example, the "Cryogenic Air Separation Condensate Recovery Device" disclosed in Chinese Utility Model Patent (Application No.: CN202322919510.6) has two significant shortcomings in practical use. First, when the condensate is low, the device can only prioritize supplying condensate to the fire water tank, which easily leads to uneven distribution of cooling water. It cannot rationally allocate water resources according to the actual needs of different water tanks, reducing the overall utilization efficiency of water resources. Second, the device uses a fan to blow air onto the radiator to cool the condensate, which has limited efficiency. Under high-temperature conditions or when the condensate flow rate is large, this method is insufficient to effectively cool the condensate to a suitable temperature, thus adversely affecting the utilization of condensate in the circulating water tank and potentially reducing the operational stability and efficiency of the circulation system.

[0004] Therefore, we have made improvements to this and proposed a cryogenic air separation condensate device. Utility Model Content

[0031] Example 1

[0032] Please refer to Figures 1-5 A cryogenic air separation condensate device includes a housing 1, a cooling chamber 13 located at the top inside the housing 1, and a water storage chamber 14 located at the bottom inside the housing 1. A heat dissipation pipe 15 is fixedly installed inside the cooling chamber 13. A vertical pipe 18 is fixedly installed at one end of the heat dissipation pipe 15, and the bottom end of the vertical pipe 18 penetrates the bottom inside the cooling chamber 13 and extends to the top inside the water storage chamber 14. An electric telescopic rod 17 is fixedly installed at the front of one side of the bottom inside the cooling chamber 13, and the driving end of the electric telescopic rod 17 penetrates the bottom inside the cooling chamber 13 and extends to the inside of the water storage chamber 14. A fixing frame 20 is fixedly installed at the driving end of the electric telescopic rod 17, and a water pump head 21 is fixedly installed on the fixing frame 20. A connecting pipe 19 is fixedly connected between the water pump head 21 and the bottom end of the vertical pipe 18.

[0033] A circulating water tank external pipe 11 is fixedly installed on the upper side of one side of the outer surface of the box 1, and the circulating water tank external pipe 11 is fixedly connected to the other end of the heat dissipation pipe 15. A fire water tank external pipe 12 is fixedly installed on the lower side of the other side of the outer surface of the box 1, and the fire water tank external pipe 12 is connected to the inside of the water storage chamber 14. A water inlet pipe 2 is fixedly installed on the other side of the outer surface of the box 1, and the water inlet pipe 2 is connected to the inside of the water storage chamber 14. A heat dissipation mechanism is provided inside the cooling chamber 13 behind the heat dissipation pipe 15.

[0034] Furthermore, such as Figure 2 and Figure 4 As shown, the heat dissipation mechanism includes a fan 24, which is fixedly installed inside the cooling chamber 13 behind the heat dissipation pipe 15. A cooling pipe 23 is fixedly installed inside the cooling chamber 13 between the heat dissipation pipe 15 and the fan 24. Coolant external pipes 3 are fixedly inserted and installed on the rear of both sides of the top of the housing 1, and the two coolant external pipes 3 are fixedly connected to the two ends of the cooling pipe 23 respectively. A heat-conducting plate 16 is fixedly installed on the outer wall of the heat dissipation pipe 15. The fan 24 is installed behind the heat dissipation pipe 15 inside the cooling chamber 13, which can accelerate airflow and enhance the air cooling effect. The cooling pipe 23 is installed between the heat dissipation pipe 15 and the fan 24, and the coolant external pipes 3 on both sides of the top can introduce coolant to enhance cooling. The corrugated heat-conducting plate 16 on the outer wall of the heat dissipation pipe 15 increases the contact area and together greatly improves the heat dissipation efficiency.

[0035] Furthermore, such as Figure 3 As shown, a liquid level sensor 22 is fixedly installed on the rear side inside the water storage chamber 14, which can monitor the condensate level in real time and provide data support for controlling the water supply to the fire water tank or circulating water tank and adjusting the height of the pump head 21 according to the liquid level, so as to realize the rational allocation of water resources and the stable operation of the system.

[0036] Furthermore, such as Figure 4 As shown, the heat-conducting plate 16 is shaped like a corrugated plate, which can increase the contact area with the cold air and the heat dissipation pipe 15, enhance the heat exchange efficiency, better transfer the heat of the condensate in the heat dissipation pipe 15 to the cold air, and improve the cooling effect on the condensate.

[0037] Furthermore, such as Figure 3 As shown, the connecting pipe 19 is made of an elastic telescopic hose, which can expand and contract with the height of the pump head 21 when the height is adjusted, ensuring the stability and sealing of the connection.

[0039] The cryogenic air separation condensate device provided in Example 1 is further optimized, specifically, as follows: Figures 1-5As shown, slots 8 are provided on the front and rear sides of the top of the housing 1. The front and back of the cooling chamber 13 are open structures. Filter frames 4 are slidably inserted into both slots 8. Filter screens 6 are fixedly installed inside the filter frames 4. A handle 5 is fixedly installed on the top of the filter frames 4.

[0040] Furthermore, such as Figures 1-5 As shown, threaded holes 9 are provided on the upper sides of both sides of the outer surface of the housing 1. A butterfly bolt 10 is threadedly connected to the threaded holes 9. Mounting grooves 7 are provided on the upper sides of both sides of the filter frame 4, and the mounting grooves 7 are threadedly connected to the butterfly bolts 10, which facilitates quick and stable installation and removal of the filter frame 4 and the filter screen 6, and makes it convenient to clean or replace them.

[0041] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, the slot 8 extends to the inner wall of the cooling chamber 13, and the slot 8 is adapted to the filter frame 4, which facilitates the secure installation of the filter frame 4.

[0042] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0043] The usage process of the cryogenic air separation condensate device provided by this utility model is as follows:

[0044] During the operation of the device, the inlet pipe 2 is fixedly connected to the air compressor drain pipe and the molecular sieve regeneration drain pipe via a tee. The fire water tank external pipe 12 is connected to the fire water tank via a water pump, and the circulating water tank external pipe 11 is also connected to the circulating water tank via a water pump. The condensate generated by the air compressor and molecular sieve flows into the water storage chamber 14 through the inlet pipe 2. The level sensor 22 monitors the condensate level entering the water storage chamber 14 in real time, and the condensate can be directly supplied to the fire water tank through the fire water tank external pipe 12. When the condensate level cannot reach the height of the pump head 21, but the circulating water tank has a water supply demand, the electric telescopic rod 17 can be activated. Its drive end drives the fixed frame 20 to move vertically, thereby causing the fixed frame 20 to move the pump head 21, achieving precise adjustment of the height of the pump head 21 so that it is immersed below the condensate level in the water storage chamber 14. Subsequently, the water pump starts, and the condensate is drawn into the connecting pipe 19 by the pump head 21, and then enters the heat dissipation pipe 15 under the guidance of the vertical pipe 18 for heat dissipation. During this period, two external coolant pipes 3 are connected to the coolant supply pipe and the return pipe respectively, and the coolant flows into the cooling pipe 23 through the external coolant pipes 3. After the fan 24 starts, it generates a high-speed airflow, which blows towards the cooling pipe 23. The coolant flowing in the cooling pipe 23 absorbs heat from the airflow and cools it down. The resulting cold air acts on the area where the heat dissipation pipe 15 is located, effectively cooling the condensate flowing in the heat dissipation pipe 15. At the same time, the heat-conducting plate 16 effectively increases the contact area between the heat dissipation pipe 15 and the cold air, further improving the cooling effect on the condensate in the heat dissipation pipe 15, ensuring that the condensate is at a suitable temperature when it flows into the circulating water pool through the external pipe 11.

[0045] During air cooling, external airflow continuously enters the cooling chamber 13. At this time, the filter screen 6, located in the airflow channel, effectively traps dust and impurities in the external airflow, preventing them from adhering to the surface of the heat sink 15. This avoids the accumulation of dust and impurities affecting the heat dissipation efficiency and lifespan of the heat sink 15. When cleaning and maintenance of the filter screen 6 is required, the operator simply loosens the wing bolt 10 and unscrews it from the mounting slot 7 of the filter frame 4. The filter frame 4 is then released from the constraint of the wing bolt 10. The operator can then quickly remove the filter screen 6 by holding the handle 5 and pulling it and the filter screen 6 along the slot 8 from inside the cooling chamber 13. After cleaning, the filter frame 4 is reinserted into the cooling chamber 13 through the slot 8 and the wing bolt 10 is tightened for fixation, completing the quick installation of the filter screen 6. This quick-installation design greatly facilitates the subsequent cleaning and maintenance of the filter screen 6, ensuring it maintains good filtration performance and guaranteeing the stable operation of the air cooling system.
