[0030] In the technical solution of the utility model, if Figure 1 and Figure 2 As shown, a first valve 17 is installed inside the delivery pipe 13 located below the discharge pipe 14, and the first valve 17 can be used to close and open the delivery pipe 13, so that the heat in the delivery pipe 13 can be delivered to the cooling water pool 2. A second valve 18 and a third valve 19 are installed inside the discharge pipe 14, and the third valve 19 is located between the heat exchange pipe 15 and the circulation pipe 16. The discharge pipe 14 can be closed and opened by the second valve 18 and the third valve 19.

[0031] When in use, firstly, the combustion process can be started by starting the boiler body 1 to generate heat and heat the water in the boiler. The heated water flows to the cooling water pool 2 through the delivery pipe 13. In this process, the water carries a large amount of waste heat. When the water passes through the discharge pipe 14, the amount of water entering the discharge pipe 14 is controlled by adjusting the first valve 17. Inside the discharge pipe 14, the amount of water entering the heat exchange pipe 15 and the circulation pipe 16 is controlled by adjusting the second valve 18 and the third valve 19. When it is necessary to recover the waste heat, the second valve 18 and the third valve 19 are opened to allow part of the water to flow into the heat exchange pipe 15. The hot water in the heat exchange pipe 15 exchanges heat with the medium in the heat exchanger 3, and the heat is transferred to the medium to realize the recovery of the waste heat. The amount of water entering the heat exchange pipe 15 can be controlled by adjusting the fourth valve 20, thereby adjusting the efficiency of the waste heat recovery. The water after the heat exchange flows back to the delivery pipe 13 through the circulation pipe 16 and continues to participate in the circulation of the boiler body. The fifth valve 21 in 16 can be used to adjust the amount of circulating water. When part of the water needs to be discharged, the fixed drainage pump 22 is started. By adjusting the switching status of the second valve 18 and the third valve 19, the water to be discharged flows through the fixed drainage pump 22 into the raw water pool 5 for discharge. At the upper end of the boiler body 1, the exhaust air pipe 6 is responsible for discharging the exhaust gas generated during the combustion process to ensure the gas circulation inside the boiler. Through the first row of pipes 8 and the second row of pipes 9 in the first connecting pipe 7, part of the water and impurities generated inside the boiler can be discharged to keep the inside of the boiler clean. On the other side of the boiler body 1, through the first furnace fixed row pipe 11 and the second furnace fixed row pipe 12 in the second connecting pipe 10, the bottom sediment in the boiler can be discharged regularly to prevent scaling and blockage. Through the above-mentioned working process, the boiler processing device with waste heat recovery function can effectively recover and utilize waste heat, improve energy utilization efficiency, and maintain the normal operation and cleanliness of the boiler.
