It should be noted that the heat in the flue gas is recovered through the desulfurization and recycling mechanism, and the flue gas can be made to fully contact with the treatment liquid to improve the desulfurization effect;
[0031] The desulfurization and recycling mechanism includes a heat preservation pipe 3, a water pipe 5, a heat conduction plate 6, a rotating shaft 7, a power motor 9, a power shaft 10, a bevel gear one 11, a bevel gear two 12, and a stirring blade 14.

It should be noted that the water inlet end and the water outlet end of the water pipe 5 are respectively connected to the external pipelines;
[0032] The heat conducting plate 6 is fixedly installed in the accommodation cavity. The rotating shaft 7 is rotatably installed on the heat preservation pipe 3. Two groups of high-temperature resistant cleaning bristles 8 are installed on the outer side of the rotating shaft 7. The power motor 9 is fixedly installed on the desulfurization tank 1. The output end of the power motor 9 is fixedly connected to the power shaft 10. The end of the power shaft 10 is fixedly connected to the first bevel gear 11. The second bevel gear 12 meshes with the first bevel gear 11 and is fixedly installed at the bottom end of the rotating shaft 7. The stirring blade 14 is fixedly installed on the outer side of the power shaft 10. It should be noted that sealing gaskets can be installed at the connection between the power shaft 10 and the desulfurization tank 1 and at the connection between the rotating shaft 7 and the heat preservation pipe 3 to ensure the sealing performance.
[0033] Through the above-mentioned desulfurization recovery mechanism, the flue gas enters the heat preservation pipe 3. When the flue gas is in the heat preservation pipe 3, the heat can be conducted through the heat conducting plate 6 into the water pipe 5 to heat the water flowing in the water pipe 5, so as to recover the heat in the flue gas. The flue gas enters the treatment liquid through the gas guide pipe 2. The power motor 9 is started, and the power shaft 10 drives the stirring blade 14 to rotate. The stirring blade 14 stirs the treatment liquid, so that the flue gas and the treatment liquid are fully mixed to ensure the desulfurization effect of the flue gas. The rotating shaft 7 drives the high-temperature resistant cleaning bristles 8 to rotate. The high-temperature resistant cleaning bristles 8 can clean the dust on the heat conducting plate 6, avoiding the adhesion of the dust in the flue gas on the heat conducting plate 6 and affecting the heat conduction effect, and thus ensuring the heat recovery effect.
[0034] Specifically, a gas guide pipe 2 is fixedly arranged between the heat preservation pipe 3 and the desulfurization tank 1. The desulfurization tank 1 is filled with treatment liquid. The end of the gas guide pipe 2 extends into the treatment liquid. A treatment liquid adding pipe 15 and a treatment liquid recovery pipe 16 are fixedly arranged on the desulfurization tank 1.

It should be noted that it is convenient for dust collection treatment. Sealing tape can be wound around the outer side of the dust collection bottle 13 to ensure the sealing performance when screwed into the discharge hole.
[0038] Working principle:
[0039] S1: The flue gas enters into the heat-insulating pipe 3. When the flue gas is in the heat-insulating pipe 3, the heat can be conducted through the heat-conducting plate 6 into the water pipe 5 to heat the water flowing in the water pipe 5, so as to recover the heat in the flue gas. The flue gas enters into the treatment liquid through the gas guide pipe 2;
[0040] S2: Start the power motor 9, which can make the power shaft 10 rotate. The power shaft 10 drives the stirring blade 14 to rotate. The stirring blade 14 agitates the treatment liquid to make the flue gas and the treatment liquid fully mixed, ensuring the desulfurization effect on the flue gas. The power shaft 10 drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the second bevel gear 12 to rotate. The second bevel gear 12 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the high-temperature cleaning brush bristles 8 to rotate. The high-temperature cleaning brush bristles 8 can clean the dust on the heat-conducting plate 6, preventing the dust in the flue gas from adhering to the heat-conducting plate 6 and affecting the heat-conducting effect, and thus ensuring the heat recovery effect.
