[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-4As shown, this utility model provides a flue gas waste heat recovery device, including a support mechanism 1. A heat-conducting mechanism 2 is provided on the surface of the support mechanism 1. The heat-conducting mechanism 2 includes a flue gas inlet pipe 201, an inclined pipe 202 fixedly connected inside the flue gas inlet pipe 201, the inclined pipe 202 penetrating the flue gas inlet pipe 201, a round cover 203 movably connected inside the top end of the inclined pipe 202, and a filter cartridge 204 fixedly connected to the bottom of the round cover 203. The bottom surface of the filter cartridge 204 is a closed structure. A filter screen is provided on the side, and a smoke inlet 205 is opened on the left side of the filter screen. An outer ring pipe 206 is fixedly connected to the inside of the side of the smoke inlet pipe 201. A left U-shaped pipe 207 is fixedly connected to the bottom surface of the left end of the bottom ... The outer ring pipe 206 is connected to the right end of the outer ring pipe 206 with a smoke exhaust pipe 210 fixedly connected inside. The support mechanism 1 includes a support leg 101, and a water bucket 102 is fixedly connected to the top of the support leg 101. The surface of the water bucket 102 is fixedly connected to the outer ring pipe 206. A left U-shaped pipe 207 and a right U-shaped pipe 209 penetrate the bottom of the water bucket 102. An inner ring pipe 208 is located inside the water bucket 102. A drain pipe 103 is fixedly connected to the bottom surface of the water bucket 102. The front of the drain pipe 103 is... The bucket 102 is equipped with a valve. The bottom end of the drain pipe 103 is threaded on the inner wall. The top of the bucket 102 is movably connected to a bucket lid 104. The top surface of the bucket lid 104 is equipped with a handle. The right side of the bucket 102 is fixedly connected to a connecting rod. One end of the connecting rod is movably connected to a disinfection box 105. The top of the disinfection box 105 is slidably connected to a box lid 106. The box lid 106 is slidably connected to a first exhaust pipe 210. The top surface of the box lid 106 is fixedly connected to a second exhaust pipe 107.

[0026] In this embodiment, when using the device, lift the handle on the lid 104 to open the lid 104, pour water into the water bucket 102 and close the lid 104. Open the box lid 106 and pour the disinfectant into the disinfection box 105, then close the box lid 106. Connect the flue gas to the flue gas inlet pipe 201. The flue gas passes through the flue gas inlet pipe 201, the inclined pipe 202, and the flue gas inlet 205 in sequence. After being filtered by the filter cylinder 204, it enters the outer ring pipe 206, the left U-shaped pipe 207, the inner ring pipe 208, and the right U-shaped pipe 209. Since the outer ring pipe 206 is located on the outside of the water bucket 102 and the inner ring pipe 208 is located on the inside of the water bucket 102, the residual heat of the flue gas is conducted to the water bucket 102 through the outer ring pipe 206 and the inner ring pipe 208. After the water is heated, the valve in the drain pipe 103 is opened to discharge the heated water. The thread on the inner wall of the bottom end of the drain pipe 103 is used to connect an external hose for easy collection of hot water. Thus, the waste heat of the flue gas is used to heat the water, which improves the convenience and practicality of the device for recovering waste heat from flue gas and heating water. After the flue gas heats the water, it drifts out from the exhaust pipe 210. Since the bottom end of the exhaust pipe 210 is close to the bottom of the disinfection box 105, the flue gas enters the disinfectant after drifting out from the exhaust pipe 210. The harmful gases in the flue gas react chemically with the disinfectant and are discharged from the exhaust pipe 107, thus completing the purification and recovery of the flue gas and improving the convenience, practicality and safety of the device for recovering flue gas.

[0027] When the filter screen needs cleaning or replacement, pull the round cover 203 out from the top of the inclined tube 202. Since the bottom of the filter cylinder 204 is a closed structure, the impurities filtered by the filter screen on the side of the filter cylinder 204 will fall to the bottom of the filter cylinder 204. The round cover 203 will drive the filter cylinder 204 to detach from the inclined tube 202. After cleaning the filter cylinder 204, put it back into the inclined tube 202 or directly replace it with a new filter cylinder 204 and put it into the inclined tube 202. This completes the maintenance of the filter screen and improves the convenience and practicality of the device for maintaining the filter screen. When the disinfectant needs to be replaced, remove the disinfection box 105 from the connecting rod on the right side of the water tank 102, open the box cover 106 and pour the disinfectant in the disinfection box 105 into the designated collection position. After cleaning the disinfection box 105, pour in new disinfectant and put the disinfection box 105 back on the connecting rod. This completes the replacement of the disinfectant and improves the convenience and practicality of the device for replacing the disinfectant.

[0028] The working principle of this flue gas waste heat recovery device will be explained in detail below.

[0029] like Figure 1-4As shown, when using, lift the handle on the bucket lid 104 to open the lid 104, pour water into the water bucket 102 and close the lid 104, open the box lid 106 and pour the disinfectant into the disinfection box 105, then close the box lid 106, and connect the flue gas to the flue gas inlet pipe 201. The flue gas passes through the flue gas inlet pipe 201, the inclined pipe 202, and the flue gas inlet 205 in sequence. After being filtered by the filter cylinder 204, it enters the outer ring pipe 206, the left U-shaped pipe 207, the inner ring pipe 208, and the right U-shaped pipe 209. Since the outer ring pipe 206 is located on the outside of the water bucket 102 and the inner ring pipe 208 is located on the inside of the water bucket 102, the residual heat of the flue gas is... Water is transferred to the water tank 102 through the outer ring pipe 206 and the inner ring pipe 208. After the water is heated, the valve in the drain pipe 103 is opened to discharge the heated water. The thread on the inner wall of the bottom end of the drain pipe 103 is used to connect to the external hose for easy collection of hot water. Thus, the waste heat of the flue gas is used to heat the water. After the flue gas heats the water, it drifts out from the exhaust pipe 210. Since the bottom end of the exhaust pipe 210 is close to the bottom of the disinfection box 105, the flue gas enters the disinfectant after drifting out from the exhaust pipe 210. The harmful gases in the flue gas react chemically with the disinfectant and are discharged from the exhaust pipe 107, thus completing the purification and recycling of the flue gas.

[0030] When the filter needs to be cleaned or replaced, pull the round cover 203 out from the top of the inclined tube 202. Since the bottom of the filter cartridge 204 is a closed structure, the impurities filtered by the filter screen on the side of the filter cartridge 204 will fall to the bottom of the filter cartridge 204. The round cover 203 will drive the filter cartridge 204 to detach from the inclined tube 202. After cleaning the filter cartridge 204, put it back into the inclined tube 202 or directly replace it with a new filter cartridge 204 and put it into the inclined tube 202 to complete the maintenance of the filter. When the disinfectant needs to be replaced, remove the disinfection box 105 from the connecting rod on the right side of the water bucket 102, open the box cover 106 and pour the disinfectant in the disinfection box 105 into the designated collection position. After cleaning the disinfection box 105, pour in new disinfectant and put the disinfection box 105 back on the connecting rod to complete the replacement of the disinfectant.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
