[0001] This application belongs to the field of steam generation technology, and specifically relates to a steam generating device. Background Technology

[0004] To address the aforementioned technical problems, this application provides a steam generating device, which aims to at least partially improve the technical problem of reduced heat exchange efficiency caused by water spraying due to the rapid temperature rise of the heated cooling water.

[0005] The technical solution of this application is as follows: A steam generating apparatus, characterized in that the apparatus comprises: The steam casing is equipped with a water inlet and a steam outlet; A heating element is disposed below the bottom of the steam housing, and there is a distance between at least one end of the heating area of ​​the heating element and the end of the bottom of the steam housing.

[0006] The steam generating device provided in this application includes a steam shell with an inlet and a steam outlet. A heating element is disposed at the bottom of the steam shell. Fluid can enter the steam shell through the inlet and, after being heated by the heating element, the generated steam can be discharged through the steam outlet.

[0007] In addition, since there is a distance between at least one end of the heating area of ​​the heating element and the bottom end of the steam shell, in actual implementation, boiling water vapor will be generated at the steam shell directly opposite the heating area of ​​the heating element and move upward. The water vapor has a low vapor content and a high density, and falls into the area between the heating area of ​​the heating element and the bottom end of the steam shell, replenishing the bottom of the steam shell directly opposite the heating area of ​​the heating element, forming a circulating flow of water vapor, so as to enhance the heat exchange efficiency between the fluid and the heating element and improve the steam generation efficiency.

[0008] In some embodiments, there is a distance between the two ends of the heating area of ​​the heating element and the two ends of the bottom of the steam shell.

[0009] As a preferred embodiment of this application, the two ends of the heating area of ​​the heating element and the two ends of the bottom of the steam shell are all at the same distance.

[0012] In some embodiments, the device further includes one or more support members supported at the bottom of the heating housing.

[0013] In some embodiments, the water inlet is located on the side of the steam housing, and the steam outlet is located on the top of the steam housing.

[0015] In some embodiments, the device further includes a water vapor separator disposed within the steam housing and positioned between the outlet end of the water inlet pipe and the steam outlet. The water vapor separator has a steam vent. Water vapor is present in the steam generated within the steam housing. The steam enters the water vapor separator from its vent, rises above it, and exits through its steam outlet. The water vapor, blocked by the water vapor separator, falls back into the steam housing and is further heated to generate steam, thereby improving the purity of the generated steam.

[0016] In some embodiments, one side of the water vapor separator is connected to the side wall of the steam housing, and there is a distance between the other side of the water vapor separator and the other side wall of the steam housing.

[0017] In some embodiments, the water vapor separator includes: The main body is disposed horizontally within the steam shell; Two first plates are arranged horizontally within the steam shell, with the two first plates positioned above the main body.

[0018] The second plate is arranged corresponding to the first plate. The second plate is arranged vertically. The opposite ends of the two first plates are connected to the ends of the main body through the second plate, so that the water vapor separator is in the shape of a "Z". Each second plate is provided with the steam vent.

[0019] In some embodiments, the water vapor separator further includes a water baffle plate connected between the two second plates, and the water baffle plate is provided with steam perforations.

[0020] In some embodiments, the water vapor separator further includes a vapor-gathering pipe, one end of which is connected to a vent hole in the baffle plate, and the other end of which extends toward the body.

[0021] In some implementations, the aperture at one end of the vapor-gathering pipe is larger than the aperture at the other end of the vapor-gathering pipe.

[0022] In some embodiments, the steam generating apparatus further includes a water level monitor for confirming the water level within the steam housing.

[0023] In some embodiments, the water level monitor includes a metal tube, an insulating tube, and a probe, the insulating tube being fitted onto a portion of the outer circumferential surface of the probe, the metal tube being fitted onto the insulating tube, and the metal tube being fixed in a mounting hole in the steam housing.

[0026] In some embodiments, the rubber rigid tube is adhesively fitted onto the outer circumferential surface of the silicone tube.

[0027] In some embodiments, the metal tube is adhesively fitted onto the outer circumferential surface of the rubber rigid tube.

After a second set time, the high-temperature structural adhesive will dry and solidify.

[0028] The water level detector provided in this application is fixed in the mounting hole on the side wall of the steam shell by a metal tube, which can withstand greater steam pressure and prevent loosening during use. The bonding method of high-temperature structural adhesive between the silicone tube and the probe's peripheral surface, between the outer peripheral surface of the silicone tube and the rubber rigid tube, and between the insulating tube and the water inlet tube can ensure the reliability of the connection seal, so as to withstand the high temperature and high pressure inside the steam shell, improve the reliability and service life of the water level detector, and has great practical value.

[0029] In some implementations, assembling the provided probe into the insulating tube specifically includes: Insert the provided probe into the silicone tube of the insulating tube, and fill the space between the two ends of the silicone tube and the periphery of the probe with high-temperature structural adhesive, and seal for a third set time.

In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments: This application discloses a steam generating device, which aims to at least partially improve the technical problem of reduced heat exchange efficiency caused by water spraying due to the rapid temperature rise of heated cooling water.

[0037] Figure 1This is a schematic diagram of the structure of a steam generator disclosed in an embodiment of this application. Figure 2 for Figure 1 A front view diagram. Combined with... Figure 1 as well as Figure 2 The steam generating device disclosed in this application includes a steam housing 100 and a heating element 200. The steam housing 100 is provided with a water inlet 101 and a steam outlet 102. The heating element 200 is disposed at the bottom of the steam housing 100. There is a distance between at least one end of the heating area of ​​the heating element 200 and the end of the bottom of the steam housing 100.

[0038] The steam generating device provided in this application includes a steam housing 100, which is provided with a water inlet 101 and a steam outlet 102. A heating element 200 is disposed below the bottom of the steam housing 100. Fluid can enter the steam housing 100 through the water inlet 101. After being heated by the heating element 200, the generated steam can be discharged through the steam outlet 102.

[0039] In addition, since there is a distance between at least one end of the heating area of ​​the heating element 200 and the bottom end of the steam shell 100, in actual implementation, boiling water vapor will be generated at the steam shell 100 directly opposite the heating area of ​​the heating element 200 and move upward. The water vapor has a low vapor content and a high density, and falls into the area between the heating area of ​​the heating element 200 and the bottom end of the steam shell 100, replenishing the bottom of the steam shell 100 directly opposite the heating area of ​​the heating element 200, forming a circulating flow of water vapor, so as to enhance the heat exchange efficiency between the fluid and the heating element 200 and improve the steam generation efficiency.

[0040] In this embodiment, the heating element 200 is disposed below the bottom of the steam shell 100. The heat generated by the heating element 200 is transferred through the steam shell 100 to the fluid inside the steam shell 100 to heat the fluid and generate the required steam.

[0041] In this embodiment, there is a distance between both ends of the heating area of ​​the heating element 200 and both ends of the bottom of the steam shell 100, thus forming... Figure 3 In the water circulation shown, the distance between the two ends of the heating area of ​​the heating element 200 and the two ends of the bottom of the steam shell 100 is preferably equal. In other embodiments, one end of the heating area of ​​the heating element 200 is flush with one end of the bottom of the steam shell 100, while the other ends are spaced apart, which can also improve heat exchange efficiency to some extent.

[0042] Figure 4 for Figure 1 A schematic diagram of the heating element. (Combined with...) Figure 4The heating element 200 in this embodiment may include a heating shell 201 and a heating tube 202. The heating shell 201 is disposed below the steam shell 100, and the side of the heating shell 201 facing the steam shell 100 is the heating area of ​​the heating element 200. There is a distance between both ends of the heating shell 201 and both ends of the bottom of the steam shell 100. The heating shell 201 is provided with a through mounting hole, and the heating tube 202 is disposed in the mounting hole of the heating shell 201. The heat generated by the heating tube 202 can be radiated through the heating shell 201 and transferred to the steam shell 100 for heat exchange with the fluid inside the steam shell 100.

[0043] The heating housing 201 in this embodiment is preferably solid, so that the heat generated by the heating tube 202 can be directly radiated through the heating housing 201, resulting in good heat transfer efficiency. Of course, in other embodiments, the heating housing 201 can also be a hollow structure, and the heat generated by the heating tube 202 can be radiated through air and the heating housing 201. The number of heating tubes 202 can be set according to the heating power requirements, and no specific limitation is made here.

[0044] Furthermore, combined Figure 1 as well as Figure 2 In this embodiment of the application, the top of the heating shell 201 and the bottom of the steam shell 100 are in contact. The two can be connected by welding or fitting to avoid energy waste caused by heat transfer through air and improve the heat exchange efficiency of the heating shell 201 and the steam shell 100.

[0045] Combination Figure 1 , Figure 2 as well as Figure 4 The steam generator shown in this application embodiment also includes a support member 300, which is supported on the bottom of the heating shell 201 so that the heating shell 201 is kept at a certain distance from the object below, so as to prevent the heat emitted from the bottom of the heating shell 201 from being radiated through other components and improve the heat utilization rate of the heating member 200.

[0046] Combination Figure 1 , Figure 2 as well as Figure 4 In this embodiment of the application, two support members 300 may be arranged opposite each other. Each support member 300 may be columnar, and each support member 300 may have two opposite connecting ear plates 301 on its top. The device can be fixed in the required position by means of the connecting ear plates 301.

[0047] Combination Figure 1 as well as Figure 2In this embodiment of the application, the water inlet 101 can be provided on the side of the steam housing 100, and the steam outlet 102 can be provided on the top of the steam housing 100. In this way, fluid can be introduced from the water inlet 101 on the side of the steam housing 100, and the generated steam can be discharged through the steam outlet 102 on the top of the steam housing 100.

[0048] Figure 5 for Figure 1 A schematic diagram of the interior of the steam shell. (Combined with...) Figure 1 , Figure 2 as well as Figure 5 The device in this embodiment of the application further includes a water inlet pipe 400 and a steam outlet pipe 500. The water inlet pipe 400 is provided with a water inlet end and a water outlet end that communicate with each other. The water inlet end of the water inlet pipe 400 is located outside the steam housing 100. It can deliver fluid into the steam housing 100 through the pump body. The water outlet end passes through the water inlet 101 and extends towards the bottom of the steam housing 100 to form an L-shape. This allows the fluid to spray out from the water outlet end of the water inlet pipe 400 close to the bottom of the steam housing 100 to avoid affecting the generated steam. The steam outlet pipe 500 is connected to the steam outlet 102 of the steam housing 100 to output the generated steam.

[0049] In this embodiment, the water inlet pipe 400 can be welded to the water inlet 101 of the steam shell 100, and the steam outlet pipe 500 can be welded or threaded to the steam outlet 102 of the steam shell 100.

[0050] The apparatus in this application embodiment also includes a water vapor separator 600. Figure 6 for Figure 1 A schematic diagram of the structure of the water vapor separator, combined with Figure 5 as well as Figure 6 The water vapor separator 600 is disposed inside the steam shell 100, and is located between the water outlet end of the water inlet pipe 400 and the steam outlet 102. The water vapor separator 600 is provided with a steam vent 601. The steam generated inside the steam shell 100 contains water vapor. The steam enters the water vapor separator 600 from the steam vent 601 and exits through the steam outlet 102. The water vapor falls back into the steam shell 100 due to the obstruction of the water vapor separator 600, and continues to be heated to generate steam, thereby improving the purity of the generated steam.

[0051] Figure 7 for Figure 1 A top view excluding the top and steam outlet pipes. (Combined with...) Figure 7In this embodiment of the application, one side of the water vapor separator 600 can be connected to the side wall of the steam shell 100, and there is a small distance between the other side of the water vapor separator 600 and the other side wall of the steam shell 100, which allows the generated steam to escape upwards.

[0052] Of course, the two sides of the water vapor separator 600 can also be connected to the two side walls of the steam shell 100 to divide the steam shell 100 into two chambers.

[0053] Combination Figure 5 as well as Figure 6 The water vapor separator 600 of this application embodiment may include a body 602, a first plate 604 and a second plate 603. The body 602 is arranged horizontally inside the steam shell 100. The first plate 604 is arranged horizontally inside the steam shell 100. There are two first plates 604 arranged opposite each other, and the two first plates 604 are arranged above the body 602. The second plate 603 is arranged correspondingly to the first plate 604. The second plate 603 is arranged vertically. The opposite ends of the two first plates 604 are connected to the ends of the second plate 603 and the body 602 respectively, so that the water vapor separator 600 is in the shape of a "Z". Each second plate 603 is provided with a steam vent 601.

[0054] like Figure 3 As shown in the embodiment of this application, the steam generator produces a bilaterally symmetrical hot water splashing circulation motion in the initial stage of heating. This can convert the water spraying phenomenon caused by rapid heating into the kinetic energy of the hot water. Moreover, the kinetic energy of the hot water moving at high speed can enhance the heat exchange efficiency between the fluid and the heating components. At the same time, some of the water carried away by the steam generated by heating can enter the cavity above the steam-water separation plate through the steam vent 601. Since the density of water vapor is less than that of water, the water vapor can be discharged through the steam outlet 102, while the separated water will flow back into the steam shell 100 under the action of gravity to achieve the separation of steam and water. This can improve the saturation of the generated steam and correspondingly generate higher temperature steam, which has good practicality.

[0055] Combination Figure 3 , Figure 5 as well as Figure 6Furthermore, the water vapor separator 600 in this embodiment of the application also includes a water baffle plate 605. The water baffle plate 605 is connected between two second plates 603 and is located above the steam vent 601. This allows the water vapor separator 600 to form a steam chamber. The water baffle plate 605 is provided with a steam vent 606. Some of the water carried away by the steam generated by heating can enter the chamber above the water vapor separator plate through the steam vent 601. Since the density of water vapor is less than that of water, the water vapor can be discharged through the steam vent 606 and the steam outlet 102 in sequence. The separated water will flow back into the steam chamber under the action of gravity. Thus, the water vapor separator undertakes the pressure relief function of spraying water in the initial stage of heating, while also realizing the separation of steam and water.

[0056] Combination Figure 5 as well as Figure 6 The water vapor separator 600 in this embodiment of the application also includes a steam-gathering pipe 607. One end of the steam-gathering pipe 607 is connected to the steam vent 606 of the water baffle plate 605, and the other end of the steam-gathering pipe 607 extends toward the body 602. However, there is a distance between the other end of the steam-gathering pipe 607 and the body 602. The steam-gathering pipe 607 can play the role of gathering and guiding the steam. Some of the water carried away by the steam generated by heating can enter the cavity above the steam-water separator plate through the steam vent 601. Since the density of water vapor is less than that of water, the water vapor can be discharged sequentially through the steam-gathering pipe 607, the steam vent 606, and the steam outlet 102. The separated water will flow back into the steam cavity under the action of gravity. Thus, the steam-water separator undertakes the pressure relief function of spraying water in the early stage of heating, and at the same time realizes the separation of steam and water.

[0057] In this embodiment, the aperture of one end of the steam-gathering pipe 607 is larger than the aperture of the other end, meaning the diameter of the steam-gathering pipe 607 decreases from top to bottom. The aperture of one end of the steam-gathering pipe 607 is typically 2 to 3 times larger than the aperture of the other end. This allows for better condensate return through the lower small aperture and steam entry into the separation chamber through the upper large aperture, achieving continuous circulation of condensate and steam. In this embodiment, the water vapor separator 600 constituting the body 602, the first plate 604, the second plate 603, and the water baffle 605 can be integrally formed. The number of steam vents 601 on the second plate 603 can be multiple, and the number of steam vents 606 on the water baffle 605 can also be multiple. In other embodiments, steam vents 601 can also be provided on the body 602, which is not limited here.

[0058] It should be noted that the water vapor separator 600 disclosed in the embodiments of this application can also be applied to other types of steam generating devices, such as steam generating devices where the heating element is located in the steam shell, etc., and there is no limitation here.

[0059] Combination Figure 1 as well as Figure 5 The steam generating device shown in this application embodiment also includes a water level monitor 700, which is installed inside the steam housing 100 to confirm the water level inside the steam housing 100 so as to replenish the fluid inside the steam housing 100 in real time and prevent dry burning.

[0060] Figure 8 for Figure 1 A schematic diagram of the structure of the water level monitor, combined with Figure 1 , Figure 5 as well as Figure 8 In this embodiment of the application, the water level monitor 700 is installed on the other side wall of the steam housing 100, and it can be arranged opposite to the water inlet pipe 400 to have sufficient installation space.

[0061] In related technologies, the water level monitor 700 includes a probe 701 for detecting the water level. An insulating rubber tube is provided on the outer peripheral surface of the probe 701. The insulating rubber tube is directly fitted into a mounting hole opened in the side wall of the steam shell 100. The pre-stress between the insulating rubber tube and the mounting hole achieves a seal between the water level monitor 700 to prevent steam leakage. However, the sealing effect of this sealing method is limited. Under the action of the steam pressure generated inside the steam shell 100, the insulating rubber is prone to loosening in the mounting hole, causing steam leakage.

[0062] Based on this, the present application also provides a water level monitor 700 to improve the sealing between the water level monitor 700 and the steam housing 100 and prevent steam leakage.

[0063] Combination Figure 8 The water level detector in this embodiment includes a metal tube 702, an insulating tube 703, and a probe 701. The insulating tube 703 is fitted onto a portion of the outer circumferential surface of the probe 701, and the metal tube 702 is fitted onto the insulating tube 703. After the water level detector is assembled, the metal tube 702 can be fixed in the mounting hole opened in the side wall of the steam housing 100 by welding or other means, so that it can withstand greater steam pressure and is not easy to loosen after long-term use, thereby achieving the purpose of preventing steam leakage.

[0064] The insulating tube 703 in this embodiment may include a silicone tube and a rubber rigid tube. The silicone tube is fitted on a portion of the outer peripheral surface of the probe 701, the rubber rigid tube is fitted on the outer peripheral surface of the silicone tube, and the metal tube 702 is fitted on the outer peripheral surface of the rubber rigid tube.

[0065] In this embodiment, the silicone tube can be bonded to a portion of the outer peripheral surface of the probe 701. The rubber tube can be made of food-grade material and can be bonded to the outer peripheral surface of the silicone tube. The metal tube 702 can be made of stainless steel to prevent rusting during use. The metal tube 702 can also be bonded to the outer peripheral surface of the rubber tube.

[0066] Based on the above-described water level monitor 700, this application embodiment also provides an installation method for the water level monitor 700, the installation method comprising: S1: Provide a metal tube 702 and fix the provided metal tube 702 into the mounting hole on the steam housing 100.

[0067] Specifically, the provided metal tube 702 can be fixed to the mounting hole on the steam shell 100 by welding.

[0068] S2: Provide probe 701 and insulating tube 703, and assemble the provided probe 701 into insulating tube 703.

[0069] Specifically: Insert the provided probe 701 into the silicone tube of the insulating tube 703, and fill the space between the two ends of the silicone tube and the periphery of the probe 701 with high-temperature structural adhesive to seal and fix it for a third set time, which can be 1h-12h. Apply high-temperature structural adhesive to the outer periphery of the silicone tube, and insert the silicone tube into the rubber rigid tube. Wait for the high-temperature structural adhesive to dry and solidify for a first set time, which can be 2h-24h. S3: Coat the outer circumferential surface of the insulating tube 703 equipped with probe 701 with high-temperature structural adhesive, and insert it into the metal tube 702. Wait for the high-temperature structural adhesive to dry and solidify. The second set time can also be 2 hours to 24 hours.

[0070] The water level detector shown in this embodiment is fixed in the mounting hole on the side wall of the steam housing 100 by the metal tube 702, which can withstand greater steam pressure and prevent loosening during use. The bonding method of high-temperature structural adhesive between the silicone tube and the peripheral surface of the probe 701, high-temperature structural adhesive between the outer peripheral surface of the silicone tube and the rubber rigid tube, and high-temperature structural adhesive between the insulating tube 703 and the water inlet pipe 400 can ensure the reliability of the connection seal, so as to withstand the high temperature and high pressure inside the steam housing 100, improve the reliability and service life of the water level detector, and has great application value.
