[0041] By adopting the above technical solutions, first, waste heat enters the filtration and purification tank 11 through the air inlet pipe 12 for filtration and purification. The purified hot air enters the converter 21 through the air delivery pipe 13. At the same time, external water is injected into the converter 21 through the water inlet pipe 22, and the hot air heats the water, thus completing the thermal energy conversion. After the hot air heats the water, the temperature drops and is discharged through the large exhaust pipe 23. The heated hot water is injected into the heat preservation tank 31 through the water supply pipe 24 for storage. When thermal energy is needed, the third valve 421 is opened, and the drainage pump 41 is started, so that the hot water in the heat preservation tank 31 is discharged through the drain pipe 35 and the water delivery pipe 42 for other uses.

[0047] By adopting the above technical solution, when there is more scale on the inner wall of the heat preservation tank 31, clean water can be injected into the heat preservation tank 31 through the feed pipe 33, and a chemical agent that can melt the scale is poured in. Then, the driving component 32 is used to drive the stirring rod 311 to rotate, so that the chemical agent reacts fully with the water and accelerates the melting of the scale.

[0048] A driving shaft 326 is rotatably installed in the heat preservation tank 31, and the driving shaft 326 is located inside the sleeve 325. A first scraper 39 is fixedly installed on the sleeve 325, and the first scraper 39 is in contact with the inner wall of the heat preservation tank 31. A second scraper 310 is fixedly installed at the bottom end of the driving shaft 326, and the second scraper 310 is in contact with the inner wall of the conical bottom of the heat preservation tank 31.

[0049] By adopting the above technical solution, the sleeve 325 drives the first scraper 39 to rotate along the inner wall of the heat preservation tank 31, and at the same time, the driving shaft 326 drives the second scraper 310 to rotate along the inner wall of the conical bottom of the heat preservation tank 31, scraping the scale on the inner wall of the heat preservation tank 31 clean.

[0050] A driving motor 321 is fixedly installed at the bottom end of the heat preservation tank 31, and the output end of the driving motor 321 is fixedly connected to the top end of the driving shaft 326.

[0051] By adopting the above technical solution, the driving motor 321 is started to drive the driving shaft 326 to rotate.

[0052] A first gear 323 is fixedly sleeved at the top end of the sleeve 325. A second gear 324 is rotatably installed at the top end inside the heat preservation tank 31, and the second gear 324 meshes with the first gear 323. A belt 322 is sleeved on the second gear 324 and the top end of the driving shaft 326.

[0053] By adopting the above technical solution, the drive shaft 326 drives the second gear 324 to rotate through the belt 322. The second gear 324 drives the sleeve 325 to rotate in the reverse direction by meshing with the first gear 323.

[0054] Conical gears 327 are fixedly installed at both ends of the drive shaft 326 close to the two stirring rods 311, and the three conical gears 327 are meshed.

[0055] By adopting the above technical solution, the drive shaft 326 drives the stirring rod 311 to rotate self - sufficiently through the conical gear 327.

[0056] A sewage discharge pipe 36 is fixedly installed on the drain pipe 35, and the sewage discharge pipe 36 is communicated with the drain pipe 35. A first valve 361 is rotatably installed at one end of the sewage discharge pipe 36.

[0057] By adopting the above technical solution, when the first valve 361 is opened, the dirt cleaned in the heat preservation tank 31 is discharged through the drain pipe 35 and the sewage discharge pipe 36.

[0058] Working principle: When the equipment system is working, first, the waste heat is recovered and purified by the waste heat recovery device 1. The purified hot gas enters the heat energy conversion device 2 for heat energy conversion. The converted heat energy enters the heat energy storage device 3 for storage. When heat energy is needed, the heat energy release device 4 releases the heat energy stored in the heat energy storage device 3 for other uses, thus achieving the purpose of recycling waste heat;

[0059] Specific operation steps: First, make the waste heat enter the filter purification box 11 through the air inlet pipe 12 for filtering and purification. The purified hot gas enters the converter 21 through the gas transmission pipe 13. At the same time, the external water source is injected into the converter 21 through the water inlet pipe 22, so that the hot gas heats the water, thus completing the heat energy conversion. After the hot gas heats the water, the temperature decreases and is discharged through the large exhaust pipe 23. The heated hot water is injected into the heat preservation tank 31 through the water supply pipe 24 for storage. The temperature monitor 312 on the heat preservation tank 31 can monitor the temperature of the hot water in the heat preservation tank 31 in real - time. When the temperature of the hot water in the heat preservation tank 31 decreases, the second valve 371 can be opened, so that the hot gas in the gas transmission pipe 13 is shunted into the hot gas pipe 38 through the heat supply pipe 37 to heat the hot water in the heat preservation tank 31. The hot gas for heating the hot water in the heat preservation tank 31 is discharged through the small exhaust pipe 34. When heat energy is needed, the third valve 421 is opened (at this time, the first valve 361 is in the closed state), and the drainage pump 41 is started, so that the hot water in the heat preservation tank 31 is discharged through the drain pipe 35 and the water transmission pipe 42 for other uses;

[0060] When there is a lot of scale on the inner wall of the heat preservation tank 31, stop the operation of the equipment, inject clean water into the heat preservation tank 31 through the feed pipe 33, and pour in chemical agents that can melt the scale. Then start the drive motor 321 to drive the drive shaft 326 to rotate. The drive shaft 326 drives the second gear 324 to rotate through the belt 322. The second gear 324 drives the sleeve 325 to rotate in the reverse direction by meshing with the first gear 323. The sleeve 325 drives the stirring rod 311 to revolve. The drive shaft 326 drives the stirring rod 311 to rotate self - by means of the bevel gear 327, so that the chemical agent reacts fully with the water, accelerating the melting of the scale. At the same time, the sleeve 325 drives the first scraper 39 to rotate along the inner wall of the heat preservation tank 31, and at the same time, the drive shaft 326 drives the second scraper 310 to rotate along the inner wall of the conical bottom of the heat preservation tank 31, scraping the scale on the inner wall of the heat preservation tank 31 clean. Then open the first valve 361 (at this time, the third valve 421 is in the closed state), so that the cleaned dirt in the heat preservation tank 31 is discharged through the drain pipe 35 and the sewage pipe 36.
