Abstract
Description
Technical Field
[0001] This patent relates to the field of molecular sieve heating, specifically a novel oxygen-generating molecular sieve heater. Background Technology
[0002] For large-scale air separation equipment, molecular sieve purification systems are currently mainly used to purify air. Molecular sieve purification systems are key devices for purifying air before it enters the low-temperature cold box in air separation equipment. A crucial step in molecular sieve purification systems is molecular sieve regeneration. Currently, molecular sieve regeneration is mainly achieved by using a combination of steam heaters and electric heaters to achieve energy saving, consumption reduction, and safe and stable operation.
[0003] However, in the process of heating the molecular sieve using a steam heater, the steam heats the molecular sieve through heat exchange in the pipeline. Existing heaters all use a coil method, in which the steam moves within the coil and heats the molecular sieve. However, due to the long length of the coil, the temperature at the lower section of the coil cannot heat the molecular sieve, resulting in uneven heating of the molecular sieve. Utility Model Content
[0004] In view of the shortcomings of existing technologies, the purpose of this patent is to provide a novel oxygen-generating molecular sieve heater.
[0005] The technical solution adopted by this patent to solve its technical problem is: a novel oxygen-generating molecular sieve heater, including an oxygen-generating molecular sieve and a steam pipeline, wherein a heating coil is sleeved on the outside of the oxygen-generating molecular sieve, the heating coil is connected to the inner cavity of the steam pipeline, and the steam pipeline is connected to an external steam device.
[0006] The side wall of the steam pipe is provided with a socket, and a connector plug is inserted into the socket. The connector plug includes a sleeve, a sliding groove, a baffle plate and a spring. The sleeve is inserted into the socket, and the inner side wall of the sleeve is provided with a sliding groove. The side wall of the baffle plate is provided with a slider, which is slidably installed in the sliding groove. One end of the spring is installed on the inner side wall of the sliding groove, and the other end of the spring is in contact with the side wall of the slider.
[0007] The heating coil can be inserted and installed inside the sleeve.
[0008] Furthermore, the heating coil includes an inlet pipe, an arc-shaped pipe, an outlet pipe, a fixing frame, and a top plate. The arc-shaped pipe is sleeved on the outside of the oxygen-generating molecular sieve. An inlet pipe is installed at one end of the arc-shaped pipe, and an outlet pipe is installed at the other end. Both the inlet and outlet pipes can be screwed into the sleeve. A fixing frame is installed in the inner cavity of both the inlet and outlet pipes. The fixing frame has a cross-shaped cross section, and a top plate is installed on the side wall of the fixing frame. The top plate can support the baffle plate.
[0009] Furthermore, the shielding plate includes a crossbar, a connecting rod, and a plate body. Both ends of the crossbar are equipped with sliders, and the crossbar is slidably installed in a sliding groove via the sliders. One end of the connecting rod is installed on the side wall of the crossbar, and the other end of the connecting rod is equipped with a plate body, which can seal the sleeve.
[0010] Furthermore, both the air inlet pipe and the air outlet pipe are provided with external threads on their outer sides, and the inner sidewall of the sleeve is provided with internal threads, so that both the air inlet pipe and the air outlet pipe can be screwed into the sleeve by the threads.
[0011] Furthermore, both the intake pipe and the exhaust pipe are provided with fixing rings on their side walls, and both the intake pipe and the exhaust pipe are fitted with sealing rings. The sealing rings can be clamped between the fixing rings and the sleeve.
[0012] Furthermore, a sealing gasket is fitted to the side wall of the plate, and the sealing gasket can fit against the side wall of the sleeve.
[0013] The beneficial effects of this patent are:
[0014] The heating coil in this device is only one ring long. By increasing the number of heating coils, the oxygen-generating molecular sieve can be wrapped and heated. One ring of heating coil can greatly shorten the distance that the steam travels, thereby avoiding heat loss from the steam and uneven heating.
[0015] In addition, a baffle is installed inside the socket of the connector plug. The baffle can seal the socket, thereby preventing steam leakage when the heating coil is not inserted. Attached Figure Description

Detailed Implementation
[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.
[0021] See Figure 1 , Figure 2 , Figure 3 This is a schematic diagram of the structure of this patent. A novel oxygen-generating molecular sieve heater includes an oxygen-generating molecular sieve 1 and a steam pipeline 2. A heating coil 3 is sleeved on the outside of the oxygen-generating molecular sieve 1. The heating coil 3 is connected to the inner cavity of the steam pipeline 2. The steam pipeline 2 is connected to an external steam device.
[0022] High-temperature steam is supplied to the steam pipeline 2 through an external steam device. The high-temperature steam enters the heating coil 3 through the connector 5 and then heats the oxygen-generating molecular sieve 1 through the heating coil 3 to promote the regeneration of the molecular sieve.
[0023] The side wall of the steam pipe 2 is provided with a socket 4, and a connector 5 is inserted into the socket 4. The connector 5 includes a sleeve 51, a sliding groove 52, a baffle plate 53 and a spring 54. The sleeve 51 is inserted into the socket 4. The inner side wall of the sleeve 51 is provided with a sliding groove 52. The side wall of the baffle plate 53 is provided with a slider 6. The slider 6 is slidably installed in the sliding groove 52. One end of the spring 54 is installed on the inner side wall of the sliding groove 52. The other end of the spring 54 is in contact with the side wall of the slider 6.
[0024] In this paper, the heating coil 3 has one turn, which greatly shortens the steam travel distance and avoids uneven heating of the oxygen-generating molecular sieve 1 due to heat loss.
[0025] Meanwhile, multiple connectors 5 are provided on the outside of the steam pipe 2, so that an appropriate number of heating coils 3 can be installed on the steam pipe 2 according to the length of the oxygen-generating molecular sieve 1 to heat the oxygen-generating molecular sieve 1.
[0026] When the heating coil 3 is installed into the connector 5, the top plate 35 on the heating coil 3 will push the baffle 53 towards the inside of the sleeve 51, so that the baffle 53 contacts the sleeve 51 to block it. At this time, the high temperature steam in the steam pipeline 2 can enter the heating coil 3 through the sleeve 51 to heat the oxygen-generating molecular sieve 1.
[0027] With the spring 54 in place, when the heating coil 3 is pulled out, the baffle 53 can automatically reset under the action of the spring 54 to block the sleeve 51 and prevent steam from leaking out of the steam pipe 2.
[0028] In this article, the side wall of the baffle plate 53 is also provided with a baffle arc plate. The side wall of the baffle plate 53 in the connector plug 5 connected to the air inlet pipe 31 is located at the upper end of the baffle plate 53, so that when the steam moves from bottom to top in the steam pipe 2, it enters the sleeve 51 and the air inlet pipe 31 due to the action of the baffle arc plate, and then enters the heating coil 3.
[0029] The lower end of the baffle plate 53 in the connector plug 5 connected to the vent pipe 33 is also provided with a baffle arc plate, which can block the steam from bottom to top. Under the drive of the steam, a negative pressure is generated at the connector plug 5 connected to the vent pipe 33, so that the steam in the heating coil 3 can flow back into the steam pipe 2 under the drive of the negative pressure, and generate circulation.
[0030] The heating coil 3 can be inserted into the sleeve 51.
[0031] The heating coil 3 includes an inlet pipe 31, an arc-shaped pipe 32, an outlet pipe 33, a fixing frame 34, and a top plate 35. The arc-shaped pipe 32 is sleeved on the outside of the oxygen-generating molecular sieve 1. The inlet pipe 31 is rotatably installed at one end of the arc-shaped pipe 32, and the outlet pipe 33 is rotatably installed at the other end of the arc-shaped pipe 32. Both the inlet pipe 31 and the outlet pipe 33 can be screwed into the sleeve 51. The fixing frame 34 is installed in the inner cavity of both the inlet pipe 31 and the outlet pipe 33. The cross section of the fixing frame 34 is cross-shaped. The top plate 35 is installed on the side wall of the fixing frame 34. The top plate 35 can support the baffle plate 53.
[0032] The air inlet pipe 31 and air outlet pipe 33 proposed in this paper are rotatably installed at both ends of the arc-shaped pipe 32. They can both rotate on the arc-shaped pipe 32, making it easy to connect with the sleeve 51 by threads. At the same time, the connection between the air inlet pipe 31, the air outlet pipe 33 and the arc-shaped pipe 32 is provided with a sealing structure to prevent steam leakage at the connection between the three.
[0033] The baffle plate 53 includes a crossbar 531, a connecting rod 532, and a plate body 533. Both ends of the crossbar 531 are equipped with sliders 6. The crossbar 531 is slidably installed in the sliding groove 52 through the sliders 6. One end of the connecting rod 532 is installed on the side wall of the crossbar 531, and the other end of the connecting rod 532 is equipped with the plate body 533. The plate body 533 can block the sleeve 51.
[0034] Both the air inlet pipe 31 and the air outlet pipe 33 have external threads on their outer sides, and the inner side wall of the sleeve 51 has internal threads. Both the air inlet pipe 31 and the air outlet pipe 33 can be screwed into the sleeve 51 by the threads.
[0035] Both the intake pipe 31 and the exhaust pipe 33 are provided with a fixing ring 7 on their side walls, and both the intake pipe 31 and the exhaust pipe 33 are fitted with a sealing ring 8. The sealing ring 8 can be clamped between the fixing ring 7 and the sleeve 51.
[0036] The sealing ring 8 ensures that the connection between the air inlet pipe 31, the air outlet pipe 33 and the sleeve 51 remains sealed, preventing steam leakage.
[0037] A sealing gasket 9 is fitted to the side wall of the plate 533, and the sealing gasket 9 can fit against the side wall of the sleeve 51.
[0038] The sealing gasket 9 can improve the sealing performance at the connection between the plate 533 and the sleeve 51.
[0039] In operation, this patented technology delivers high-temperature steam into the steam pipeline 2 via an external steam device. This high-temperature steam then enters the heating coil 3 through the connecting plug 5, and heats the oxygen-generating molecular sieve 1 through the heating coil 3, promoting the regeneration of the molecular sieve. The heating coil 3 has only one rotation, which greatly shortens the steam travel distance, thereby avoiding uneven heating of the oxygen-generating molecular sieve 1 due to heat loss. At the same time, multiple connecting plugs 5 are provided on the outside of the steam pipeline 2, allowing an appropriate number of heating coils 3 to be installed on the steam pipeline 2 according to the length of the oxygen-generating molecular sieve 1, in order to heat the oxygen-generating molecular sieve 1.
