[0029] In order to recover and convert the heat energy carried by the high-temperature flue gas, the first smoke conveying pipe 61 is interference fit with one side of the smoke exhaust chimney 2, and one end of the first smoke conveying pipe 61 extends into the first smoke storage box 4, so that the smoke in the smoke exhaust chimney 2 is transmitted to the first smoke storage box 4 through the first smoke conveying pipe 61, the heating water tank 62 is fixedly arranged at the bottom end of the inner cavity of the first smoke storage box 4, the steam pipe 63 is interference fit with one side of the top of the heating water tank 62, and the high-temperature flue gas heats the heating water tank 62 to make the water in the heating water tank 62 boil, the steam generator 64 is fixedly arranged at the top of the first smoke storage box 4, one end of the steam pipe 63 is screwed to the air inlet of the steam generator 64, and the steam is discharged upward through the steam pipe 63 into the steam generator 64 to generate electricity, thereby realizing energy conversion.

[0030] In order to replenish the water in the heating water tank 62, a water tank 65 is fixedly arranged at the top of the second smoke storage box 5, and the bottom end of the water tank 65 is located in the second smoke storage box 5. A water pump 66 is fixedly arranged at the top of the water tank 65. A water inlet pipe 67 is screwed to the water inlet of the water pump 66, and one end of the water inlet pipe 67 extends into the water tank 65. A water outlet pipe 68 is screwed to the water outlet of the water pump 66, and one end of the water outlet pipe 68 extends into the inner cavity of the heating water tank 62. Under the suction of the water pump 66, the water in the water tank 65 can be pumped into the heating water tank 62. It is sucked out through the water inlet pipe 67 and discharged into the heating water tank 62 through the water outlet pipe 68 for replenishment. The liquid level meter 69 is fixedly arranged on one side of the inner cavity of the heating water tank 62. The PLC controller 610 is fixedly arranged on the front side of the second smoke storage box 5. The PLC controller 610 is electrically connected to the liquid level meter 69. The PLC controller 610 is electrically connected to the water pump 66. When the water in the heating water tank 62 boils and decreases below the lowest water level line of the liquid level meter 69, the liquid level meter 69 transmits the electrical signal to the PLC controller 610.

[0031] As a preferred solution, further, the heating water tank 62 and the water storage tank 65 are both made of heat-conducting materials to accelerate the boiling of water.

[0032] As a preferred solution, further, the smoke cooling assembly 7 includes: a fan 71, a smoke inlet pipe 72, a smoke outlet pipe 73 and a second liquid infusion pipe 74;

[0033] In order to be able to transmit the smoke, the fan 71 is fixedly arranged on the top of the water storage box 65, the smoke inlet pipe 72 is screwed to the air inlet of the fan 71, and one end of the smoke inlet pipe 72 is interference fit with one side of the first smoke storage box 4, the smoke outlet pipe 73 is screwed to the air outlet of the fan 71, and one end of the smoke outlet pipe 73 extends into the second smoke storage box 5, the second smoke delivery pipe 74 is screwed to one side of the second smoke storage box 5, and one side of the second smoke delivery pipe 74 is connected to one side of the smoke monitor 8.

[0034] As a preferred solution, further, the smoke outlet pipe 73 and the second smoke delivery pipe 74 are located on both sides of the second smoke storage box 5, so that the smoke passes through the entire second smoke storage box 5, so that the water storage tank 65 is heated evenly.

[0035] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0036] Step 1: During monitoring, the smoke in the smoke exhaust pipe 2 is transmitted to the first smoke storage box 4 through the first smoke delivery pipe 61, so that the high-temperature smoke heats the heating water tank 62, so that the water in the heating water tank 62 boils, and the steam is discharged upward through the steam pipe 63 into the steam generator 64 to generate electricity, thereby realizing energy conversion and effectively utilizing the heat energy carried by the smoke;

[0037] Step 2: When the high-temperature flue gas passes through the first smoke storage box 4, part of the heat is taken away by the heated water tank 62, and the fan 71 is started. Under the suction force of the fan 71, the smoke can be sucked out of the first smoke storage box 4 through the smoke inlet pipe 72, and then discharged into the second smoke storage box 5 through the smoke outlet pipe 73. Part of the heat is dissipated during the transmission process between the smoke inlet pipe 72 and the smoke outlet pipe 73, and the water storage tank 65 is preheated in the second smoke storage box 5, thereby greatly reducing the temperature of the smoke. Finally, the smoke is discharged into the smoke monitor 8 through the second smoke delivery pipe 74 for smoke data monitoring, so as to avoid damage to the smoke monitor 8 caused by excessively high smoke temperature, and make the monitoring data more accurate;

[0038] Step three: When the water in the heating water tank 62 boils and decreases below the lowest water level line of the liquid level gauge 69, the liquid level gauge 69 transmits an electrical signal to the PLC controller 610, so that the PLC controller 610 controls the water pump 66 to start. Under the suction force of the water pump 66, the water in the water tank 65 can be sucked out through the water inlet pipe 67, and discharged into the heating water tank 62 through the water outlet pipe 68 for replenishment, so that steam is continuously generated, which effectively saves energy and is suitable for wide promotion.
