[0002] Corn stalks refer to the stems, leaves, and other parts remaining after the corn crop is harvested. Corn stalks have many uses and are an important production resource for industrial and agricultural production. Moreover, corn stalks can be used as fuel to heat water or other media. In the heating process, steam heat exchange components are required for heat exchange.

[0003] As disclosed in CN219473611U, a by-product steam heat exchange device includes a shell, which comprises a tank. Graphite blocks are disposed on the inner side of the tank, and a feed inlet is located at the top of the tank. A heat exchange mechanism is disposed on the inner side of the tank, including a water inlet fixedly connected to the surface of the tank. A water flow channel is provided on the inner side of the tank. Material holes are opened on the inner side of the graphite blocks, and water flow holes are opened on the inner side of the tank. This invention allows water to enter through the water inlet. Material enters through the feed inlet, generating high temperatures, and then flows downwards, heating the external water in the opposite direction. Simultaneously, the water cools the material, achieving a heat exchange effect. It also produces by-product steam, preventing heat loss from the steam and ensuring good heat exchange efficiency. The by-product steam allows for the recovery of waste heat, thereby reducing energy consumption in material processing.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-7 .

[0040] To address the problems of incomplete combustion of corn stalks, difficulty in collecting and cleaning dust generated during combustion, and significant environmental pollution caused by the direct discharge of flue gas after combustion heat exchange in existing technologies, this solution employs a dedicated steam heat exchange component for corn stalks. This component includes a combustion chamber 1 and a heat exchange tower 9 fixed to the upper part of the combustion chamber 1. A combustion frame 2 is fixedly connected to the middle of the combustion chamber 1, and the combustion frame 2 has equally spaced through slots 3 in its middle. Below the through slots 3 is a device for... The dust collection drawer 5 is inserted into the bottom of the combustion chamber 1 and forms a detachable structure at the bottom of the combustion chamber 1. The heat exchange tube assembly is set in the heat exchange tower 9. The heat exchange tube assembly consists of a heat exchange tube frame 10 fixed in the middle of the heat exchange tower 9, an inclined tube 11 fixed at the lower end of the heat exchange tube frame 10, and a collection hopper 12 fixed at the lower end of the inclined tube 11. A processing box 13 is fixedly connected to the upper end of the heat exchange tube frame 10. A suction fan 14 is installed on the top of the processing box 13. An activated carbon filter purification screen 15 is inserted into the middle of the processing box 13.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a combustion rack 2 is fixedly connected to the middle of the combustion chamber 1, and a through groove 3 is provided in the combustion rack 2. First, the corn stalks to be burned are placed on the combustion rack 2 and then ignited. Corn stalks to be burned are continuously added to the combustion rack 2. Through holes 4 are provided on both the left and right sides of the combustion chamber 1. The air flow in the combustion chamber 1 is accelerated through the through holes 4, so that the air can fully contact with oxygen during the combustion process, achieving a more complete combustion effect. The dust generated during the combustion process falls into the movable drawer 5 through the through groove 3 for collection. After the combustion is over, the limit on the movable baffle 7 can be released by rotating the fixing bolt 8. Then, the movable baffle 7 is flipped over. The movable baffle 7 rotates at the lower end of the combustion chamber 1 and disengages from the front of the movable drawer 5, thereby releasing the limit on the movable drawer 5. Then, the handle 6 is pulled to the right to move the movable drawer 5 out from the bottom of the combustion chamber 1, so as to facilitate the cleaning of the dust collected in the movable drawer 5.

[0042] A heat exchange tower 9 is fixedly connected to the upper end of the combustion chamber 1. The heat exchange tower 9 adds an appropriate amount of water through the water inlet valve at the upper end, so that the heat exchange tube rack 10 is submerged in water. Then, the flue gas generated during the process rises through the collection hopper 12 and the inclined tube 11 into the heat exchange tube rack 10 and fully contacts the cold water in the heat exchange tower 9, heating the cold water to achieve the heat exchange effect. The hot water after heat exchange can be discharged through the drain valve at the lower end of the heat exchange tower 9 for use. A treatment box 13 is fixedly connected to the upper end of the heat exchange tube rack 10. A suction fan 14 is installed at the upper end of the treatment box 13. The suction fan 14 can extract the low-temperature flue gas after heat exchange to prevent the flue gas from escaping. An activated carbon filter 15 is inserted and installed in the treatment box 13. The activated carbon filter 15 can filter and purify the flue gas, reducing the pollution to the environment after discharge.

[0043] In addition, when it is necessary to disassemble, clean, and replace the activated carbon filter 15, such as Figure 6 and Figure 7 As shown, the limiting component comprises a fixed rod 16 fixed to the front and rear sides of the upper right end of the processing box 13, a fixed pressure plate 17 sleeved on the outer surface of the fixed rod 16, a fixed cap 18 for pressing and limiting, and protrusions 19 fixed to the front and rear sides of the lower right end of the processing box 13. By rotating the fixed cap 18 threadedly connected to the outer surface of the fixed rod 16, the fixed cap 18 disengages from the fixed pressure plate 17, thereby releasing the limitation on the fixed pressure plate 17. Then, the fixed pressure plate 17 is pulled to the right, and the fixed pressure plate 17 slides between the fixed rod 16 and the fixed rod 16. The fixed pressure plate 17 is then disengaged from the right end of the protrusion 19 and the activated carbon filter 15. The fixed pressure plate 17 is then rotated, causing it to rotate relative to the fixed rod 16. This allows the fixed pressure plate 17 to move away from the right end of the activated carbon filter 15, thereby releasing the restriction and interference on the activated carbon filter 15. The activated carbon filter 15 can then be pulled out of the processing box 13, facilitating its disassembly, cleaning, and replacement, and preventing clogging during long-term use.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
