[0017] In order to make the content of the utility model more clearly understood, the utility model is further described below based on specific embodiments in combination with the accompanying drawings.

[0018] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0019] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0020] like Figures 1 to 4 As shown, a fire self-filtering device based on thermoelectric effect is shown, the mounting plate 1 can be installed at any position on the wall, or above the channel wall, when the high-temperature smoke passes through the hot-end ceramic piece 2, the hot-end ceramic piece 2 will be subjected to high-temperature conduction to form a hot end, and a condenser 5 is movably installed above the cold-end ceramic piece 4, through the condensation effect of the condenser 5, a temperature difference is formed between the cold-end ceramic piece 4 and the hot-end ceramic piece 2, the hot-end ceramic piece 2 and the thermocouple pair 3 and the cold-end ceramic piece 4 are all movably connected with the guide plate, and the heat energy is converted into electrical energy, that is, heat The electric effect connects the hot-end ceramic piece 2 and the cold-end ceramic piece 4 of two conductors or semiconductors of different materials with the guide plate to form a closed loop. When there is a temperature difference between the hot-end ceramic piece 2 and the cold-end ceramic piece 4 at the two contact points of the two conductors, an electromotive force is generated between the two, thereby forming a current in the loop. The guide plate is electrically connected to the electrostatic plate 10, and is also electrically connected to a current-stabilizing and voltage-stabilizing connector to stabilize the current and voltage, so that the electrostatic plate 10 can effectively absorb dust, achieve the effect of self-dust absorption, and complete the purpose of energy saving and emission reduction.

[0021] The mounting plate 1 is installed above the channel wall so that the high-temperature flue gas passes through the bottom end of the movable shell 15 at the same time. A graphene plate is fixedly installed at the bottom end of the movable shell 15. The graphene plate has a high-temperature conduction function, so that heat is conducted. The air below the piston expands due to the heat, pushing the piston upward, and pushing the air above the piston into the suction shell 12 through the through hole opened in the movable shell 15. The air flow causes the turbine 13 to rotate the connecting shaft 7, and the rotation of the connecting shaft 7 drives the rotating wheel 8 to rotate. The rotation of the rotating wheel 8 drives the condensate in the condensation shell 6 to rotate, thereby accelerating the heat conduction of the condenser tube 5 and enhancing the condensation effect.

[0022] Through the stretching of the spring, the hot air under the piston expands due to the heat. Since the gas molecules become larger, the heat is dissipated. The elastic force of the spring allows the piston to reciprocate inside the movable shell 15. When the piston moves downward, the one-way valve 14 opens, allowing the smoke to enter the interior of the suction shell 12 through the one-way valve 14. The piston moves upward again, and the turbine 13 rotates, allowing the smoke to enter the dust removal shell 9 through the through hole. The smoke is adsorbed by the electrostatic plate 10, so that the smoke is filtered through the filter plate 11 and collected by the dust collecting slot opened in the dust removal shell 9, completing self-filtration and extending the escape time.

[0023] In summary, the beneficial effects of this embodiment are: achieving the effect of self-dust suction, achieving the purpose of energy saving and emission reduction, effectively utilizing the heat of fire smoke, completing self-filtration, reducing the impact of smoke in fire, extending the escape time, and at the same time, easy installation, increased practicality.

[0024] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
