Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-2. An energy-saving smoke exhaust mechanism of a steam generator in this embodiment includes a base plate 1, a steam generator body 3 is fixed to the upper surface of the base plate 1, an installation box 6 is fixed to the upper surface of the base plate 1, a utilization mechanism 2 is provided inside the installation box 6, a discharge mechanism 4 is provided inside the installation box 6, a smoke exhaust pipe 5 is fixedly connected to the top of the steam generator body 3, a partition 7 is horizontally fixed to the inner wall of the inner cavity of the installation box 6, an inclined plate 8 is fixed to the right side wall of the inner cavity of the installation box 6, a support frame 9 is fixed to the left side wall of the inner cavity of the installation box 6, and a water tank 10 is fixed to the inside of the support frame 9 by bolts.

The inclined plate 8 is fixed between the front and rear side walls of the inner cavity of the installation box 6. The inclined plate 8 is located below the partition 7. The inclined plate 8 is used to guide the liquefied water vapor to flow into the water storage tank 10. Two discharge ports are opened on the right side of the installation box 6 and close to the bottom of the installation box 6. The smoke exhaust pipe 5 is fixedly connected to the left side of the installation box 6, and the upper surface of the installation box 6 is fixedly connected to a liquid injection pipe.

Please refer to Figure 3. In order to recycle heat, the utilization mechanism 2 in this embodiment includes a disc tube 201 fixed to the back wall of the inner cavity of the installation box 6, a fixed tube 202 is fixed to the lower surface of the partition 7, a water pump 203 is fixed to the upper surface of the installation box 6, the pumping end of the water pump 203 is connected to the pumping pipe 204, and the drainage end of the water pump 203 is connected to the drainage pipe 205.

The fixed pipe 202 in this example is fixedly connected to the bottom end of the coil pipe 201, and the end of the smoke exhaust pipe 5 away from the steam generator body 3 is connected to the left end of the coil pipe 201. The high-temperature flue gas is transmitted to the interior of the coil pipe 201 through the smoke exhaust pipe 5. The end of the water pumping end away from the water pump 203 passes through the upper surface of the installation box 6 and extends to the interior of the installation box 6 and is close to the inner bottom wall of the installation box 6. The interior of the installation box 6 and above the partition 7 are filled with an aqueous solution. Since the flue gas contacts the heat transfer surface of the inner wall of the coil pipe 201 inside the coil pipe 201 and reaches the dew point temperature, water vapor condenses, thereby exchanging heat with the external aqueous solution, causing the temperature of the aqueous solution to increase, thereby recycling a large amount of energy in the flue gas, thereby achieving energy saving and environmental protection.

It should be noted that the high-temperature flue gas is transmitted to the interior of the coil pipe 201 through the smoke exhaust pipe 5. Since the flue gas contacts the heat transfer surface of the inner wall of the coil pipe 201 inside the coil pipe 201 and reaches the dew point temperature, water vapor condenses, thereby exchanging heat with the external aqueous solution, raising the temperature of the aqueous solution, thereby recycling a large amount of energy in the flue gas, thereby achieving energy saving and environmental protection.

Please refer to Figure 4. In order to discharge the smoke, the discharge mechanism 4 in this embodiment includes a motor 401 fixed to the right side of the installation box 6. The outer side of the output shaft of the motor 401 is connected to a belt 402 through a transmission wheel. The left side wall of the inner cavity of the installation box 6 and close to the bottom of the installation box 6 is rotatably connected to a rotating rod 403 through a bearing.

The discharge mechanism 4 in this example also includes two activated carbon plates 404 fixed on the right side of the support frame 9. The two activated carbon plates 404 and the support frame 9 are fixed on the front and rear side walls of the inner cavity of the installation box 6. The right end of the rotating rod 403 passes through the right side wall of the inner cavity of the installation box 6 and extends to the right side of the installation box 6 and is connected to the inside of the belt 402 through a transmission wheel. A plurality of fan blades are fixed on the outside of the rotating rod 403. The flue gas moves to the inside of the two activated carbon plates 404, and the two activated carbon plates 404 are used to filter the flue gas. Then, the motor 401 is started to make the belt 402 drive the rotating rod 403 to rotate, so that the plurality of fan blades rotate to make the air flow and speed up the circulation of the flue gas.

It should be noted that the smoke is filtered using two activated carbon plates 404, and then the motor 401 is started, so that the belt 402 drives the rotating rod 403 to rotate, so that the multiple fan blades rotate to make the air flow and speed up the circulation of the smoke.

The main controller can be a conventionally known device that plays a control role such as a computer. The control circuit of the main controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail. At the same time, the parts not described in detail in the utility model are all common knowledge to technicians in this field.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 it can be 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 the present invention can be understood by specific circumstances.

The working principle of the above embodiment is:

(1) When the energy-saving smoke exhaust mechanism of the steam generator is needed, the high-temperature smoke is transmitted to the interior of the coil pipe 201 through the smoke exhaust pipe 5. Since the smoke contacts the heat transfer surface of the inner wall of the coil pipe 201 inside the coil pipe 201 and reaches the dew point temperature, water vapor condenses, thereby exchanging heat with the external aqueous solution, raising the temperature of the aqueous solution, thereby recycling a large amount of energy in the smoke, thereby achieving energy-saving and environmental protection effects.

(2) However, there are still harmful substances to the human body in the cooled flue gas, which need to be filtered. The liquefied water vapor is guided by the inclined plate 8 so that the liquefied water vapor flows into the interior of the water storage tank 10, and the flue gas moves to the interior of the two activated carbon plates 404. The flue gas is filtered by the two activated carbon plates 404, and then the motor 401 is started to make the belt 402 drive the rotating rod 403 to rotate, so that the multiple fan blades rotate to make the air flow, thereby accelerating the circulation speed of the flue gas.

It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
