[0040] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.
[0041] Figure 1 is a schematic structural diagram of a gas heating device 100 provided in an embodiment of the present application. Figure 2 yes Figure 1 A schematic diagram of the structure of the first hot gas channel 2 after being expanded in the horizontal direction, Figure 3 yes Figure 1 Schematic diagram of the structure after the first cold air channel 3 is unfolded in the horizontal direction.
[0042] See also Figure 1 , Figure 2 and Figure 3The gas heating device 100 comprises: a heating device 1, a first hot air channel 2 and a first cold air channel 3. The inlet end of the first hot air channel 2 is connected to the heating device 1, and the outlet end is connected to the external space. The inlet end and the outlet end of the first cold air channel 3 are both connected to the external space, and the first hot air channel 2 is attached to the first cold air channel 3.
[0043] Among them, the heating device 1 is used to provide heat for heating gas. Since the inlet end of the first hot air channel 2 is connected to the heating device 1 and the outlet end is connected to the external space, the first hot air channel 2 can transport the hot air generated by the heating device 1 to the external space, thereby increasing the temperature of the gas in the external space. Then, since the inlet end and the outlet end of the first cold air channel 3 are both connected to the external space, the first hot air channel 2 is attached to the first cold air channel 3, so that the gas in the external space can flow in from the inlet end of the first cold air channel 3 and flow out from the outlet end of the first cold air channel 3. In this process, the heat carried by the hot air in the first hot air channel 2 can be transferred to the gas in the first cold air channel 3, and transported to the external space along with the gas in the first cold air channel 3, thereby making the heat dissipation efficiency of the hot air higher. The improvement of the heat dissipation efficiency of the hot air improves the utilization rate of thermal energy, so it can reduce energy consumption and thus reduce the heating cost.
[0044] In addition, the first hot air channel 2 and the first cold air channel 3 are both narrow and long pipes, which increases the heat dissipation area of the hot air and further improves the heat dissipation efficiency of the hot air, that is, it can further improve the utilization rate of thermal energy, reduce energy consumption and reduce heating costs.
[0045] It should be noted that the above-mentioned heating device 1 can be an electric heating device, a fuel heating device, or other heating devices 1 with the same function, and the embodiments of the present application do not limit this.
[0046] It should also be noted that the first hot air channel 2 and the first cold air channel 3 may be metal channels, ceramic channels, or channels made of other materials with the same functions, which is not limited in the embodiments of the present application.
[0047] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first hot air channel 2 and / or the first cold air channel 3 are provided with a blower 4. Since the blower 4 can speed up the flow rate of the gas, the flow rate of the hot air in the first hot air channel 2 and / or the gas in the first cold air channel 3 can be accelerated, thereby avoiding local accumulation of heat, so that the heat dissipation efficiency of the hot air can be further improved, the utilization rate of thermal energy can be improved, and the energy consumption and heating cost can be reduced.
[0048] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The blower device 4 is provided with an automatic regulating device 5, which can regulate the power of the blower device 4. In this way, the technician can automatically regulate the power of the blower device 4 according to the heating demand, that is, the flow rate of the hot air in the first hot air channel 2 and / or the gas in the first cold air channel 3 can be automatically regulated, and then the heat dissipation efficiency of the hot air can be regulated, so the speed at which the gas temperature in the external space rises can be regulated.
[0049] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first hot air channel 2 and the first cold air channel 3 are both curved channels, and the curved channels extend in the same direction. Since the curved channel is longer than the straight channel in the same space, the heat dissipation path of the hot air in the first hot air channel 2 is longer. In this way, the heat dissipation of the hot air in the first hot air channel 2 is more thorough, thereby improving the heat dissipation efficiency of the hot air, improving the utilization rate of thermal energy, and reducing energy consumption and heating costs.
[0050] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first hot air channel 2 and the first cold air channel 3 are both folded channels, the extension direction of the folded channels is the vertical direction, and they are centrally arranged to form a first heat exchange part 6.
[0051] Since the density of hot air is lower than that of cold air, the hot air will flow upwards autonomously. In this way, setting the extension direction of the folded channel to the vertical direction is conducive to accelerating the flow speed of the hot air. Next, since the volume occupied by the folded channel is small, it is conducive to reducing the total volume of the gas heating device 100. Finally, since the path of the folded channel is long and has bends, when the hot air flows through the folded channel, the ash it carries can be deposited, so the ash content of the exhaust gas can be reduced.
[0052] In order to make full use of the heat generated by the heating device 1, in some embodiments, see Figure 1 , Figure 2 and Figure 3 The gas heating device 100 further includes a second hot air channel and a second cold air channel 7, wherein the inlet end of the second hot air channel is connected to the outlet end of the first hot air channel 2, and the outlet end is communicated with the external space, and the inlet end of the second cold air channel 7 is connected to the outlet end of the first cold air channel 3, and the outlet end is communicated with the external space. The second hot air channel and the second cold air channel 7 are closely fitted.
[0053] After the hot air in the first hot air channel 2 exchanges heat with the gas in the first cold air channel 3, the temperature is still high. After adding the second hot air channel and the second cold air channel 7 and making them fit closely together, the heat of the hot air after passing through the first hot air channel 2 can be further utilized. In this way, the heat generated by the heating device 1 can be fully utilized, thereby improving the utilization rate of thermal energy, so that energy consumption and heating costs can be reduced.
[0054] In some embodiments, see Figure 1 , Figure 2 and Figure 3 , the second hot air channel and the second cold air channel 7 are both folded channels, the extension direction of the folded channels is horizontal, and they are centrally arranged to form the second heat exchange part 8. In this way, setting the extension direction of the folded channels to the horizontal direction is conducive to reducing the flow speed of the hot air in the second hot air channel, so that the heat of the hot air can be fully absorbed by the second cold air channel 7. Then, the volume occupied by the folded channels is small, which is conducive to reducing the total volume of the gas heating device 100. Finally, since the path of the folded channels is long and has bends, when the hot air flows through the folded channels, the ash it carries can be deposited, so the ash content of the exhaust gas can be reduced.
[0055] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first cold air channel 3 includes a plurality of first cold air sub-channels 31, and each first cold air sub-channel 31 is in contact with the first hot air channel 2. In this way, the contact area between the first cold air channel 3 and the first hot air channel 2 can be increased, and the heat of the hot air in the first hot air channel 2 can be fully absorbed by the first cold air channel 3, so that the utilization rate of heat energy can be improved, and the energy consumption and heating cost can be reduced.
[0056] And / or, the second cold air channel 7 includes a plurality of second cold air sub-channels, each of which is in contact with the second hot air channel. The working principle and technical effect are the same as those described above, so they will not be described here.
[0057] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The heating device 1 includes a combustion stove 11, which is used to use renewable biomaterials as fuel for heating. In this way, renewable biomaterials can be used as fuel. Since biomaterials are naturally formed and renewable, they can meet the requirements of green environmental protection and make full use of renewable energy.
[0058] In some embodiments, see Figure 1 and Figure 4The heating device 1 includes a hot air cavity 12, and the inlet end of the first hot air channel 2 is connected to the hot air cavity 12. The hot air cavity 12 is used to generate hot air after being heated, and the larger the hot air cavity 12 is, the more hot air is generated. In this way, more hot air can be provided for the heat exchange between the first hot air channel 2 and the first cold air channel 3, so that the heat generated by the heating device 1 can be fully utilized, so that energy consumption and heating costs can be reduced.
[0059] See also Figure 1 and Figure 4 , discloses a specific gas heating device 100, which is a double-channel hot blast furnace. In addition to the features of the gas heating device 100 itself, the double-channel hot blast furnace also includes a protective shell 9 wrapped around the first heat exchange part 6 and the surface of the first heat exchange part 6, and a fuel inlet 91 is provided on the protective shell 9. The fuel inlet 91 is connected to the first hot gas channel 2 and is used to fill the fuel. The inlet ends of the multiple first cold gas sub-channels 31 are separately arranged in different directions of the protective shell 9.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
