[0025] Example 2;
[0026] like Figure 1-4As shown, the system includes a base 1, with several evenly distributed support columns 2 at the bottom of the base 1, a combustion chamber 3 on one side of the top of the base 1, a conveying cylinder 4 connected to the combustion chamber 3 on one side, the conveying cylinder 4 being connected to the base 1 via a support block 5, a feeding hopper 6 on one side of the top of the conveying cylinder 4, a slag discharge hopper 7 penetrating the base 1 at the bottom of the combustion chamber 3, a slag screen plate 8 inside the combustion chamber 3, a smoke collection hood 9 at the top of the slag screen plate 8, a filter box 10 extending outside the combustion chamber 3 at the top of the smoke collection hood 9, a smoke exhaust pipe 11 at the top of the filter box 10, a flue gas purification component inside the filter box 10, an anti-backburning hood 12 on the inner wall of the combustion chamber 3, a burner nozzle 13 extending into the combustion chamber 3 on one side of the combustion chamber 3, and an air supply pipe 14 on one side of the combustion chamber 3 located at the burner nozzle 13, with one end of the air supply pipe 14 extending into the combustion chamber 3. The conveying cylinder 4 is equipped with a conveying auger 15, the shaft of which extends outside the conveying cylinder 4 and is connected to the drive end of a motor 16. A cleaning door 17 is connected to one side of the combustion chamber 3, and a cleaning door 18 is provided on one side of the filter chamber 10. The flue gas purification assembly includes a dust filter 19 in the filter chamber 10, which is connected to the filter chamber 10 via an elastic element. A rotating shaft 20 is located at the top of the dust filter 19, and symmetrically arranged cams 21 are fixedly fitted onto the outer wall of the rotating shaft 20. A filling frame 22 is located at the top of the rotating shaft 20, and several evenly distributed flow holes 23 are opened on the outer wall of the filling frame 22.

As the cam 21 rotates, it intermittently squeezes the dust filter screen 19, thus filtering the dust. The mesh 19 is vibrated by the elastic compression of the spring 28, shaking off the surface dust. When the flue gas passes through the flow hole 23 and the filling frame 22, it is adsorbed by the activated carbon 24. By setting the flue gas purification component, the flue gas generated during the combustion process of the burner can be filtered and discharged, improving its environmental protection. At the same time, the dust filter in the flue gas purification component can filter the dust in the flue gas, and the elastic element, rotating shaft and cam in the flue gas purification component can vibrate the dust filter to prevent the dust from clogging the filter holes and affecting its filtration efficiency. The filling frame and activated carbon in the flue gas purification component can adsorb and purify the harmful gases in the flue gas, preventing them from flowing into the external environment and polluting the environment.
[0028] In summary, by utilizing the above-mentioned technical solution of this utility model, the flue gas purification component can filter and discharge the flue gas generated during the combustion process of the burner, thereby improving its environmental friendliness. At the same time, the dust filter in the flue gas purification component can filter dust in the flue gas, and the elastic element, rotating shaft, and cam in the flue gas purification component can vibrate the dust filter to prevent dust from clogging the filter holes and affecting its filtration efficiency.
