[0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes, which is mainly different from fossil fuels. The application of biomass fuel is actually mainly biomass molded fuel, which uses agricultural and forestry wastes as raw materials, and is made into various shapes (such as blocks, granules, etc.) through processes such as crushing, mixing, extrusion and drying. It is a new type of clean fuel that can be directly burned. When burning biomass fuel, a boiler is required; the superheater is a component in the boiler used to increase the steam temperature. By increasing the enthalpy of steam, the steam's working capacity is increased and the thermal cycle efficiency is improved.

When the roller 811 on the unloading push plate 809 contacts the unloading opening and closing plate 823, the limit bending rod 824 on the unloading opening and closing plate 823 moves in the limit bending frame 825, and the telescopic spring 1 826 is squeezed. At this time, the unloading opening and closing plate 823 opens to unload the dust and solid impurities, and the dust and solid impurities are uniformly collected through the collection channel 805;

[0050] Step three, then repeat the operation, when the roller 811 is separated from the unloading opening and closing plate 823, the telescopic spring 826 is reset to close the unloading opening and closing plate 823, and the filtered flue gas enters the discharge channel 6 through the rotating circular tube 812 and contacts the superheater body 10, while filtering the flue gas, start the drive motor 815, and drive the driving motor 815 to drive the rotating push rod 821 to make the push wheel 822 move in the slideway of the T-shaped tooth plate 820, so that the tooth block end of the T-shaped tooth plate 820 moves back and forth in an arc shape, so that the linkage gear 818 drives the adjusting gear 816 to rotate in both directions, so that the filter cartridge 813 rotates in both directions at the same time.

[0051] Working principle: the smoke generated during combustion enters the processing channel 5 through the smoke exhaust channel 4, at which time the smoke is blocked by the U-shaped partition 804, and the smoke is preliminarily filtered by the filter cartridge 813, so that the dust and solid impurities in the smoke fall to one side of the U-shaped partition 804 by gravity. At this time, the filter holes below the filter cartridge 813 are closed by the T-shaped blocking block 806, and then the dust and solid impurities on the U-shaped partition 804 are pushed by the starting electric drive rod 808 to drive the unloading push plate 809. When the roller 811 on the unloading push plate 809 contacts the unloading opening and closing plate 823, the limit bending rod 824 on the unloading opening and closing plate 823 moves in the limit bending frame 825, and the telescopic spring 826 is squeezed at the same time. At this time, the material discharging opening and closing plate 823 is opened to discharge the dust and solid impurities, and the dust and solid impurities are uniformly collected through the collecting channel 805, and then the operation is repeated. When the roller 811 is separated from the material discharging opening and closing plate 823, the telescopic spring 826 is reset to close the material discharging opening and closing plate 823, and the filtered flue gas enters the discharge channel 6 through the rotating circular tube 812 and contacts the superheater body 10. While filtering the flue gas, the driving motor 815 is started, and the driving motor 815 drives the rotating push rod 821 to make the push wheel 822 move in the slideway of the T-shaped tooth plate 820, so that the tooth block end of the T-shaped tooth plate 820 moves back and forth in an arc shape, so that the linkage gear 818 drives the adjusting gear 816 to rotate in both directions, so that the filter cartridge 813 At the same time, it rotates in both directions. When the smoke is discharged, the smoke passes through the smoke exhaust channel 4. The opening and closing size of the smoke exhaust opening and closing plate 1104 is adjusted according to the amount of dust collected in the smoke, so as to improve the effect of collecting dust in the smoke. When the amount of dust in the smoke is large, the servo motor 1110 is started at this time, and the servo motor 1110 drives one of the two-way screws 1107 to make the other two-way screw 1107 rotate at the same time, so that the nut slide 1106 moves in opposite directions in the limiting track 1105, so that the pushing cylinder 1108 on the nut slide 1106 drives the installation adjustment frame 1103 to reduce the opening and closing degree of the smoke exhaust opening and closing plate 1104, so as to effectively collect the dust in the smoke and avoid excessive smoke emission, which has an impact The effect on dust collection in the flue gas is that when the amount of dust in the flue gas is small, the smoke exhaust opening and closing degree of the smoke exhaust opening and closing plate 1104 is increased, and the smoke enters the filter channel 7 after being heated. At this time, the smoke is secondary filtered through the filter plate 912 to reduce the damage of the smoke to the equipment. The filtering is started at the same time, and the notched gear 909 on the rotating round rod 908 is driven by the universal motor 913 to rotate. When the tooth block end of the notched gear 909 is engaged with the linkage gear rod 906, the slider 902 moves inside the slide groove 901, and the reset spring 904 is squeezed. When the notched gear 909 is separated from the linkage gear rod 906, the reset spring 904 rebounds quickly, so that the filter plate 912 is in vibration to filter the smoke.
