DETAILED DESCRIPTION

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figure 1-Figure 3 As shown, an energy-saving silane combustion cylinder comprises a combustion cylinder body 1, a heat recovery component 9 and a waste heat utilization component 13, an air intake pipe 2 is connected to one side of the lower side of the combustion cylinder body 1, and an outer shell body 6 is installed on the outside of the combustion cylinder body 1, a lower hopper 3 is arranged on the lower side of the combustion cylinder body 1, and a lower feed pipe 4 is connected to the lower side of the lower hopper 3, and an ash collecting bucket 5 is installed at the bottom of the lower feed pipe 4; a side shell body 7 is fixed to one side of the outer shell body 6, and a heat exchange water tank 8 is arranged inside the side shell body 7, a first exhaust pump 11 is installed on the right side of the outer side of the exhaust filter cartridge 10, and a return pipe 12 is connected to the lower side of the first exhaust pump 11, and the bottom end of the return pipe 12 is connected to the air intake pipe 2;

[0021] The specific operation is as follows: the silane waste gas is mixed with compressed air and then sent into the interior of the combustion cylinder 1 through the air intake pipe 2 for combustion. The dust generated by the combustion can settle through the lower hopper 3 and the lower pipe 4 to enter the interior of the ash collecting bucket 5, and the hot air flow generated by the combustion can rise and enter the interior of the exhaust filter cartridge 10. The outer shell 6 and the side shell 7 can insulate the combustion cylinder 1 and the heat exchange water tank 8. The first exhaust pump 11 and the reflux pipe 12 can facilitate the return of some of the incompletely burned silane waste gas to the interior of the air intake pipe 2 and re-discharge it into the interior of the combustion cylinder 1 for re-combustion.

[0022] like Figure 1-Figure 2As shown, a heat recovery assembly 9 is provided between the heat exchange water tank 8 and the combustion cylinder 1, and the heat recovery assembly 9 includes a water pump 901, a water supply pipe 902, an annular heat exchange pipe 903, a connecting pipe 904 and heat transfer fins 905. The upper outer side of the heat exchange water tank 8 is connected to the water supply pipe 902 through the water pump 901, and the other side of the water supply pipe 902 is provided with an annular heat exchange pipe 903, the annular heat exchange pipe 903 is attached to the outer side of the combustion cylinder 1, and the annular heat exchange pipes 903 are connected with the connecting pipe 904. The outer wall of the combustion cylinder 1 is also fixed with heat transfer fins 905, and the heat transfer fins 905 are distributed between the annular heat exchange pipes 903. The heat recovery assembly 9 also includes a return pipe 906, and one side of the lowermost annular heat exchange pipe 903 is connected to the return pipe 906 through the water pump 901, and the end of the return pipe 906 is connected to the heat exchange water tank 8.

[0023] The specific operation is as follows: the water inside the heat exchange water tank 8 is conveniently delivered to the inside of the annular heat exchange tube 903 through the water pump 901 and the water supply pipe 902, and the multiple annular heat exchange tubes 903 connected to each other are distributed on the outside of the combustion cylinder 1. While dissipating the heat and cooling the combustion cylinder 1, the heat can also be recycled and utilized, which plays a role in energy saving. The heat-conducting fins 905 on the outer wall of the combustion cylinder 1 can conduct heat to the upper and lower sides of the annular heat exchange tube 903, thereby improving the heat exchange and heat recovery efficiency. The return water pipe 906 is convenient for returning the absorbed heat to the inside of the heat exchange water tank 8 and circulating water supply for heat exchange.

[0024] like Figure 2 As shown, an exhaust filter cartridge 10 is connected to the top of the combustion cylinder 1, and a waste heat utilization component 13 is arranged on the rear side of the exhaust filter cartridge 10, and a filter medium layer is filled on the top of the interior of the exhaust filter cartridge 10, and the waste heat utilization component 13 includes a second exhaust pump 1301, an air supply pipe 1302 and a circulating heat exchange pipe 1303, and a second exhaust pump 1301 is installed on the upper rear side of the exhaust filter cartridge 10, and an air supply pipe 1302 is connected to the rear side of the second exhaust pump 1301, and a circulating heat exchange pipe 1303 is arranged at the end of the air supply pipe 1302; the waste heat utilization component 13 also includes a circulating heat exchange pipe 1303 and an air outlet pipe 1304, and the circulating heat exchange pipe 1303 is "U"-shaped and circularly attached to the outer side of the heat exchange water tank 8, and the rear of the circulating heat exchange pipe 1303 is connected to the air outlet pipe 1304;

[0025] The specific operation is as follows: the upper part of the interior of the exhaust filter cartridge 10 is filled with a filter medium layer to filter and remove dust from the hot air flow, thereby preventing dust in the subsequent air flow from adhering to the inner wall of the circulating heat exchange tube 1303 and affecting the heat exchange efficiency. The second exhaust pump 1301 and the air supply pipe 1302 are used to facilitate the delivery of the filtered air flow into the interior of the circulating heat exchange tube 1303, so that the circulating heat exchange tube 1303 in a "U"-shaped circulation shape and attached to the outside of the heat exchange water tank 8 can exchange heat with the water inside the heat exchange water tank 8, thereby further recycling the waste heat and achieving energy-saving effect.

[0026] In summary, if Figure 1-Figure 3 As shown, when the energy-saving silane combustion cylinder is used, the silane exhaust gas can first be mixed with compressed air and then sent to the interior of the combustion cylinder 1 through the air inlet pipe 2 so that it can be burned therein, and then the dust generated by the combustion can settle through the lower hopper 3 and the lower pipe 4 to enter the interior of the ash collecting bucket 5. In this process, the water in the heat exchange water tank 8 can be sent to the interior of the annular heat exchange tube 903 through the water pump 901 and the water supply pipe 902. Multiple annular heat exchange tubes 903 that are interconnected are distributed on the outside of the combustion cylinder 1. While dissipating heat and cooling the combustion cylinder 1, the heat can also be recycled and utilized, which plays a role in energy saving. The heat-conducting fins 905 on the outer wall of the combustion cylinder 1 can conduct heat to the upper and lower sides of the annular heat exchange tube 903. Finally, the water that has absorbed heat can be returned to the interior of the heat exchange water tank 8 through the water pump 901 and the return water pipe 906 for circulating water supply and heat exchange.

[0027] Then the hot air flow generated by the combustion can rise and enter the interior of the exhaust filter cartridge 10. At this time, part of the incompletely burned silane exhaust gas can be returned to the interior of the intake pipe 2 through the first exhaust pump 11 and the reflux pipe 12 and re-discharged into the interior of the combustion cylinder 1 for re-combustion. In addition, the upper part of the interior of the exhaust filter cartridge 10 is filled with a filter medium layer to filter and remove dust from the hot air flow. Then, the hot air flow after combustion in the combustion cylinder 1 is filtered and then sent to the interior of the circulating heat exchange tube 1303 through the second exhaust pump 1301 and the air supply pipe 1302. The circulating heat exchange tube 1303, which is in a "U"-shaped circulation shape and is attached to the outside of the heat exchange water tank 8, can exchange heat with the water inside the heat exchange water tank 8, thereby further recycling the waste heat and achieving energy-saving effects. In this way, the use process of the energy-saving silane combustion cylinder is completed.
