[0027] The utility model provides a methanol reforming combustion hot water steam integrated machine to reduce equipment costs and save energy consumption. Detailed description will be given below with reference to specific embodiments.
[0028] like Figure 1 As shown, an embodiment of the present invention provides a methanol reforming combustion hot water steam integrated machine, including a methanol reforming combustion furnace 1, a steam pressure vessel 2 and a hot water tank 3 connected to each other; a metal heat exchange tube 21 is provided in the steam pressure vessel 2, and the metal heat exchange tube 21 includes a water inlet end 211 and a water outlet end 212, the water inlet end 211 of the metal heat exchange tube 21 passes through the wall of the steam pressure vessel 2 and extends to the outside of the steam pressure vessel 2, and the water outlet end 212 of the metal heat exchange tube 21 passes through the wall of the steam pressure vessel 2 and is inserted into the hot water tank 3; the methanol reforming combustion furnace 1 is provided below the steam pressure vessel 2 for heating the steam pressure vessel 2.
[0029] It should be noted that the steam pressure vessel 2 is used to store water. When the steam pressure vessel 2 is heated, the water therein can be heated and evaporated into steam; and the water inlet end 211 of the metal heat exchange tube 21 passes through the wall of the steam pressure vessel 2 and extends to the outside of the steam pressure vessel 2, and the water outlet end 212 of the metal heat exchange tube 21 passes through the wall of the steam pressure vessel 2 and is inserted into the hot water tank 3, so that water can enter from the water inlet end 211 of the metal heat exchange tube 21 and flow out from the water outlet end 212 of the metal heat exchange tube 21 and finally enter the hot water tank 3. When the water flows through the metal heat exchange tube 21, it can obtain heat in the steam pressure vessel 2, thereby being heated into hot water, and thus the water that finally enters the hot water tank 3 is hot water.
[0030] In this embodiment, a methanol reforming combustion furnace 1 is disposed below a steam pressure vessel 2 and can heat the steam pressure vessel 2 so that the water in the steam pressure vessel 2 is heated and evaporated into steam, thereby providing steam. A metal heat exchange tube 21 is disposed within the steam pressure vessel 2, and a water inlet end 211 of the metal heat exchange tube 21 passes through the wall of the steam pressure vessel 2 and extends outside the steam pressure vessel 2. A water outlet end 212 of the metal heat exchange tube 21 passes through the wall of the steam pressure vessel 2 and is inserted into a hot water tank 3. Water flowing through the metal heat exchange tube 21 and into the hot water tank 3 can obtain heat from the steam pressure vessel 2 and be indirectly heated into hot water, thereby providing hot water. That is, this all-in-one unit can simultaneously integrate the functions of burning steam and burning hot water, avoiding the problem of complex configuration of pipes, accessories, etc. required by the simultaneous provision of a steam boiler and a hot water boiler, which would result in higher equipment costs. In addition, the hot water provided by the hot water tank 3 is heated by utilizing the heat within the steam pressure vessel 2, eliminating the need for an additional combustion furnace to heat the hot water tank 3 separately. This achieves efficient energy utilization and helps save energy.
[0031] Alternatively, as Figure 1 and Figure 2 As shown, the steam pressure vessel 2 and the hot water tank 3 are horizontally arranged in sequence.
[0032] In this optional embodiment, the steam pressure vessel 2 and the hot water tank 3 are arranged horizontally in sequence. In this way, under the premise that the methanol reforming combustion furnace 1 is located below the steam pressure vessel 2, the hot water tank 3 can be relatively close to the methanol reforming combustion furnace 1, so that the hot water tank 3 itself is also heated to a certain extent by the combustion furnace. Combined with the heating effect of the metal heat exchange tube 21, the water in the hot water tank 3 can be heated faster, thereby improving the heating efficiency of the hot water.
[0033] Alternatively, as Figure 1 and Figure 2 As shown, the steam pressure vessel 2 is horizontally arranged in a cylindrical shape, and the metal heat exchange tube 21 is spirally extended along the axial direction of the steam pressure vessel 2.
[0034] Specifically, a hook can be provided on the inner wall of the steam pressure vessel 2, and the metal heat exchange tube 21 can be hung on the hook to fix the metal heat exchange tube 21 relative to the steam pressure vessel 2. It should be noted that the metal heat exchange tube 21 is arranged to extend helically along the axial direction of the steam pressure vessel 2, which means that the metal heat exchange tube 21 is generally helical, and the axis of the helical structure is parallel to the axial direction of the steam pressure vessel 2 (i.e., the Y-axis direction).
[0035] In this optional embodiment, the metal heat exchange tube 21 is spirally extended along the axial direction of the steam pressure vessel 2, which can increase the surface area of the metal heat exchange tube 21, thereby improving the heat exchange efficiency and further improving the heating efficiency of hot water.
[0036] Alternatively, as Figure 2 As shown, the outer wall of the steam pressure vessel 2 is connected to a water inlet pipe 22 and a steam pipe 23 , and both the water inlet pipe 22 and the steam pipe 23 are connected to the upper position of the outer wall of the steam pressure vessel 2 .
[0037] It should be noted that the water inlet pipe 22 can be connected to a water source so as to inject water from the water source into the steam pressure vessel 2, and the steam pipe 23 can be connected to an external device that uses steam.
[0038] In this optional embodiment, the water inlet pipe 22 is connected to the upper position of the outer wall of the steam pressure vessel 2 to reduce the pressure during the water injection process into the steam pressure vessel 2 and improve the water injection efficiency; steam is usually generated in the upper part of the inner cavity of the steam pressure vessel 2, and by connecting the steam pipe 23 to the upper position of the outer wall of the steam pressure vessel 2, the generated steam can be quickly discharged.
[0039] Alternatively, as Figure 2 As shown, a water inlet float valve 221 is installed at the connection between the water inlet pipe 22 and the steam pressure vessel 2.
[0040] In this optional embodiment, a water inlet float valve 221 is installed at the connection between the water inlet pipe 22 and the steam pressure vessel 2. In this way, the water from the water inlet pipe 22 needs to pass through the water inlet float valve 221 before entering the steam pressure vessel 2. The water inlet float valve 221 can automatically open or close according to the change of the water level, ensuring that the water level in the steam pressure vessel 2 remains within the set range, avoiding the water level being too high and limiting the space required for steam generation, resulting in the inability to effectively accumulate and discharge steam.
[0041] Alternatively, as Figure 2 As shown, the outer wall of the hot water tank 3 is connected to a hot water pipe 31 , the middle of the hot water pipe 31 is connected to a cold water pipe 32 , and a thermostatic valve 33 is provided at the connection between the hot water pipe 31 and the cold water pipe 32 .
[0042] It should be noted that the cold water pipe 32 can be connected to a water source, so that water from the water source is injected into the hot water pipe 31 to change the water temperature of the water flowing out of the hot water pipe 31 .
[0043] In this optional embodiment, the outer wall of the hot water tank 3 is connected to a hot water pipe 31, the middle of the hot water pipe 31 is connected to a cold water pipe 32, and a thermostatic valve 33 is provided at the connection between the hot water pipe 31 and the cold water pipe 32. In this way, the thermostatic valve 33 can be used to adjust the cold water flow of the cold water pipe 32 and the hot water flow of the hot water pipe 31, so that the water temperature of the water finally discharged from the hot water pipe 31 is within an appropriate temperature range, ensuring that the hot water provided by the hot water tank 3 has a more constant and appropriate temperature.
[0044] Alternatively, as Figure 1 As shown, the methanol reforming combustion hot water steam integrated machine also includes a machine base 4, the methanol reforming combustion furnace 1 is installed on the upper end of the machine base 4, the steam pressure vessel 2 and the hot water tank 3 are fixed to the upper end of the machine base 4 through a bracket, and the steam pressure vessel 2 is suspended above the methanol reforming combustion furnace 1.
[0045] In this optional embodiment, the steam pressure vessel 2 and the hot water tank 3 are fixed to the upper end of the machine base 4 by a bracket, so that the steam pressure vessel 2 and the hot water tank 3 have a stable positional relationship relative to the methanol reforming combustion furnace 1, thereby ensuring the heating effect of the methanol reforming combustion furnace 1 on the steam pressure vessel 2 and the hot water tank 3.
[0046] Alternatively, as Figure 1 As shown, movable wheels 41 are installed at the lower end of the base 4.
[0047] It should be noted that a plurality of movable wheels 41 may be provided, and the plurality of movable wheels 41 are evenly distributed at the lower end of the machine base 4 .
[0048] In this optional embodiment, movable wheels 41 are installed at the lower end of the base 4. In this way, the all-in-one machine with movable wheels 41 can be flexibly installed in different working environments to adapt to different space layouts and usage requirements.
[0049] Alternatively, as Figure 1 As shown, the methanol reforming combustion furnace 1 includes a furnace body 11 and a methanol reforming catalyst 12, and the furnace body 11 is provided with a fuel cavity 111 and a metal coil 112 arranged from bottom to top, and the fuel cavity 111 is provided with a combustion assembly, and the methanol reforming catalyst 12 is respectively connected to one end of the metal coil 112 and the fuel cavity 111; the methanol reforming combustion hot water steam integrated machine also includes a methanol container 5, and the methanol container 5 is connected to the other end of the metal coil 112; the steam pressure vessel 2 is provided with a temperature controller 24, and the temperature controller 24 is connected to the igniter of the fuel cavity 111, and is used to temperature-control the start and stop of the igniter of the fuel cavity 111, so that the low threshold start ignition meets the hot water temperature requirement, and the high threshold stop ignition meets both the steam temperature requirement and the steam pressure vessel safety requirement.
[0050] Specifically, the combustion assembly may include an igniter, a combustion tube 15, and a combustion-supporting tube 16. The combustion-supporting tube 16 is provided through the upper cavity wall of the fuel cavity 111 to provide combustion-supporting gas to the upper end of the fuel cavity 111. The combustion tube 15 is provided through the upper cavity wall of the fuel cavity 111 to guide the fuel in the fuel cavity 111 to the upper end of the fuel cavity 111. The igniter may be provided at the upper end of the fuel cavity 111 to ignite the combustion-supporting gas and fuel. Specifically, the upper end of the furnace body 11 may be open so that the heat generated by the combustion in the furnace body 11 is transferred upward to the steam pressure vessel 2 above the combustion furnace.
[0051] In the prior art, a methanol reforming combustion furnace 1 is usually provided with a heating device to heat the methanol introduced into the furnace body 11, thereby facilitating the reforming and catalytic processing of the methanol in the methanol reforming catalyst 12. The gas generated after the reforming and catalytic processing is then introduced into the fuel cavity 111 and ignited and burned by the combustion component. However, the additional heating device will increase energy consumption, thereby increasing the cost of use. In this optional embodiment, the methanol reforming catalyst 12 is respectively connected to one end of the metal coil 112 and the fuel cavity 111, and the methanol container 5 is connected to the other end of the metal coil 112, that is, the methanol container 5, the metal coil 112, the methanol reforming catalyst 12 and the fuel cavity 111 are connected in sequence; and the metal coil 112 is arranged above the fuel cavity 111, so that when the combustion assembly burns the fuel in the fuel cavity 111, the heat generated by the combustion flows upward to heat the metal coil 112. Therefore, when the methanol provided by the methanol container 5 flows to the methanol reforming catalyst 12 and the fuel cavity 111, it will be heated in the metal coil 112 by the heat generated by the combustion of the combustion furnace itself. There is no need to set up an additional heating device to heat the methanol separately, which is beneficial to reducing the energy consumption of the combustion furnace and thus reducing the cost of use.
[0052] Alternatively, as Figure 1 As shown, the methanol reforming catalyst 12 is arranged on the outside of the furnace body 11, and one end of the methanol reforming catalyst 12 is connected to the metal coil 112 through a first metal connecting pipe 13 passing through the wall of the furnace body 11, and the other end of the methanol reforming catalyst 12 is connected to the fuel cavity 111 through a second metal connecting pipe 14 passing through the wall of the furnace body 11.
[0053] In this alternative embodiment, it is also possible to position the methanol reforming catalyst 12 within the furnace body 11, next to or below the fuel chamber 111, to achieve an integrated design of the furnace body 11 and the methanol reforming catalyst 12. It is also possible to eliminate the combustion-supporting combustion pipe 16 and rely solely on air entering through the furnace housing 11 for combustion support. It is also possible to eliminate the base 4 and wheels 41, converting the mobile design into a fixed one. All of these variations fall within the scope of protection of this utility model patent.
[0054] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
