[0032] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0033] like Figure 1 , 2As shown, a biomass-fired organic heat carrier furnace with an anti-ash blocking structure comprises an upper furnace body 1, a lower furnace body 2, an ash hopper 3, a first radiation section furnace tube 4, a second radiation section furnace tube 5, a first convection section coil 6, a second convection section coil 7 and a third convection section coil 8;

[0034] The lower furnace body 2 is provided with a first radiation chamber 9, a first convection chamber 10 and a second convection chamber 11 arranged in sequence;

[0035] The upper furnace body 1 is connected to the upper end of the lower furnace body 2, and a second radiation chamber 12 and a third convection chamber 13 are provided in the upper furnace body 1;

[0036] The second radiation chamber 12 is located above the first radiation chamber 9 and the first convection chamber 10, and the lower end of the second radiation chamber 12 is connected to the first radiation chamber 9 and the first convection chamber 10 respectively;

[0037] The third convection chamber 13 is located above the second convection chamber 11 and communicates with the second convection chamber 11;

[0038] The ash hopper 3 is connected to the lower end of the lower furnace body 2 and is located below the first convection chamber 10 and the second convection chamber 11. A settling chamber 14 is provided in the ash hopper 3. The lower end of the first convection chamber 10 and the lower end of the second convection chamber 11 are respectively connected to the settling chamber 14.

[0039] The first radiation section furnace tube 4 is arranged in the first radiation chamber 9, the second radiation section furnace tube 5 is arranged in the second radiation chamber 12, the first convection section coiled tube 6 is arranged in the first convection chamber 10, the second convection section coiled tube 7 is arranged in the second convection chamber 11, and the third convection section coiled tube 8 is arranged in the third convection chamber 13;

[0040] The distribution of the pipes in the first convection section coil 6 is sparser than that in the third convection section coil 8, and the distribution of the pipes in the second convection section coil 7 is also sparser than that in the third convection section coil 8. Specifically, the flow path of the flue gas is to flow through the first radiation chamber 9, the second radiation chamber 12, the first convection chamber 10, the settling chamber 14, the second convection chamber 11 and the third convection chamber 13 in sequence; wherein, the first convection section coil 6 in the first convection chamber 10 and the second convection section coil 7 in the second convection chamber 11 are most likely to be blocked by ash, so the pipes in the first convection section coil 6 and the second convection section coil 7 are arranged more sparsely than those in the third convection section coil 8, so that the pipe gap in the first convection section coil 6 and the pipe gap in the second convection section coil 7 are both relatively large, and then the smoke in the flue gas is not easy to be blocked in the first convection section coil 6 and the second convection section coil 7, thereby avoiding the problem of ash blocking. When the smoke flows through the settling chamber 14, the smoke in the smoke will settle in the ash hopper 3, thereby reducing the possibility of smoke adhering to the second convection section coil 7 and the third convection section coil 8, further avoiding the ash blockage problem. In addition, the provision of the ash hopper 3 also greatly facilitates the user to clean the ash, improves the convenience of cleaning, and solves the problem of difficult cleaning. Among them, the third convection section coil 8 is a conventional coil in the prior art.

[0041] In this embodiment, the distribution of the pipes in the first convection section coil 6 is more sparse than that in the second convection section coil 7 .

[0042] like Figure 1 As shown, the biomass-fired organic heat carrier furnace with an anti-ash blocking structure may also include a partition 15, which is installed in the upper furnace body 1 and the lower furnace body 2, and the upper end of the partition 15 is located between the second radiation chamber 12 and the third convection chamber 13, and the lower end of the partition 15 is located between the first convection chamber 10 and the second convection chamber 11.

[0043] like Figure 1 As shown, the upper furnace body 1 is provided with a flue outlet 16 connected to the third convection chamber 13. The flue gas flows into the third convection chamber 13 and is then discharged from the flue outlet 16. The flue outlet 16 is used to connect to a waste heat recovery device.

[0044] like Figure 1 , 2As shown, the biomass-fired organic heat carrier furnace with an anti-ash blocking structure may also include a combustion chamber 17 and a grate 18, wherein the combustion chamber 17 is located below the first radiation chamber 9, and at least a portion of the grate 18 is located in the combustion chamber 17; specifically, various biomass pellets can be burned on the grate 18 to generate high-temperature flue gas, and the flue gas flows from the combustion chamber 17 through the first radiation chamber 9, the second radiation chamber 12, the first convection chamber 10, the settling chamber 14, the second convection chamber 11 and the third convection chamber 13 in sequence, and then is discharged from the flue outlet 16 to the waste heat recovery device. Since the pipes in the first convection section coil 6 and the second convection section coil 7 are sparsely distributed and the gaps between the pipes are large, the smoke in the flue gas is not easy to be blocked in the first convection section coil 6 and the second convection section coil 7, thereby avoiding the ash blocking phenomenon. To be more specific, the flue gas flows from the first convection chamber 10 into the settling chamber 14, and then flows into the second convection chamber 11 from below. The smoke dust in the flue gas will settle in the ash hopper 3, reducing the possibility of smoke dust adhering to the second convection section coil 7 and the third convection section coil 8.

[0045] To be more specific, compared with some single-layer furnace bodies in the prior art, an upper furnace body 1 is arranged at the upper end of the lower furnace body 2 in the present embodiment, so that the overall height is greatly increased, that is, the total height of the first radiation chamber 9 and the second radiation chamber 12 is greatly increased, so that the smoke in the flue gas can more easily fall back to the grate 18 at the bottom in the first radiation chamber 9 and the second radiation chamber 12, thereby reducing the smoke entering the first convection chamber 10, thereby avoiding ash blockage.

[0046] like Figure 1 As shown, the biomass-fired organic heat carrier furnace with an anti-ash blocking structure may also include an inlet pipe assembly and an outlet pipe assembly;

[0047] The inlet pipe assembly is used to receive the heat transfer oil and is respectively connected to the inlet of the third convection section coil 8 and the inlet of the second convection section coil 7;

[0048] The outlet of the third convection section coiled pipe 8 is connected to the inlet of the second radiation section furnace tube 5;

[0049] The outlet of the second convection section coil 7 is communicated with the inlet of the first convection section coil 6, and the outlet of the first convection section coil 6 is communicated with the inlet of the first radiation section furnace tube 4;

[0050] The outlet of the first radiation section furnace tube 4 and the outlet of the second radiation section furnace tube 5 are respectively connected to the outlet pipe assembly.

[0051] like Figure 1 As shown, the inlet pipe assembly may include an inlet manifold 19, an upper inlet branch pipe 20 and a lower inlet branch pipe 21;

[0052] The inlet main pipe 19 is used to receive the heat transfer oil and is connected to the upper inlet branch pipe 20 and the lower inlet branch pipe 21 respectively;

[0053] The upper inlet branch pipe 20 is connected to the inlet of the third convection section coil 8;

[0054] The lower inlet branch pipe 21 is connected to the inlet of the second convection section coil 7 .

[0055] like Figure 1 As shown, the outlet pipe assembly may include an outlet main pipe 22, an upper outlet branch pipe 23 and a lower outlet branch pipe 24;

[0056] The outlet main pipe 22 is communicated with the upper outlet branch pipe 23 and the lower outlet branch pipe 24 respectively;

[0057] The upper outlet branch pipe 23 is connected to the outlet of the second radiation section furnace tube 5;

[0058] The lower outlet branch pipe 24 is connected to the outlet of the first radiation section furnace tube 4 .

[0059] Specifically, the inlet manifold 19 is used to connect the heat transfer oil, and the outlet manifold 22 is used to connect with the pipeline of the heating circulation system. After the heat transfer oil flows into the inlet manifold 19, one path of the heat transfer oil flows through the upper inlet branch pipe 20, the third convection section coil 8, the second radiation section furnace tube 5 and the upper outlet branch pipe 23 in sequence and then converges into the outlet manifold 22, and the other path of the heat transfer oil flows through the lower inlet branch pipe 21, the second convection section coil 7, the first convection section coil 6, the first radiation section furnace tube 4 and the lower outlet branch pipe 24 in sequence and then converges into the outlet manifold 22, and then the heat transfer oil in the outlet manifold 22 flows into the pipeline of the heating circulation system again.

[0060] In summary, the flow path of the flue gas is to flow through the first radiation chamber 9, the second radiation chamber 12, the first convection chamber 10, the settling chamber 14, the second convection chamber 11 and the third convection chamber 13 in sequence. Among them, the first convection section coil 6 in the first convection chamber 10 and the second convection section coil 7 in the second convection chamber 11 are most likely to be blocked by ash, so the pipelines in the first convection section coil 6 and the second convection section coil 7 are arranged more sparsely than in the third convection section coil 8, so that the pipeline gap in the first convection section coil 6 and the pipeline gap in the second convection section coil 7 are both relatively large, and then the smoke in the flue gas is not easy to be blocked in the first convection section coil 6 and the second convection section coil 7, thereby avoiding the problem of ash blocking. And when the flue gas flows through the settling chamber 14, the smoke in the flue gas will settle in the ash hopper 3, thereby reducing the possibility of smoke adhering to the second convection section coil 7 and the third convection section coil 8, further avoiding the problem of ash blocking. Moreover, the provision of the ash hopper 3 greatly facilitates the user to clean the ash, improves the convenience of cleaning the ash, and solves the problem of difficult cleaning.
