[0040] Reference Figure 6 As shown, specifically, an air outlet pipe 14 is fixedly connected to one side of the outer shell 1, an air collecting plate 15 is fixedly connected to the other end of the air outlet pipe 14, a first butterfly valve 16 is fixedly connected to the outside of the air outlet pipe 14, and a fan 17 is fixedly connected to the inside of the air outlet pipe 14. During the heating process, the flue gas is repeatedly circulated to improve the utilization rate of the flue gas.

[0041] Reference Figure 6 As shown, specifically, a smoke exhaust pipe 18 is fixedly connected to the rear side of the air outlet pipe 14, and a second butterfly valve 19 is fixedly connected to the outer side of the smoke exhaust pipe 18. After the heating is stopped, the smoke can be discharged to the outside through the smoke exhaust pipe 18.

[0042] Reference Figure 5As shown, specifically, a heater 20 and a water pump 22 are fixedly connected to the top of the shell 1, a heating pipe 21 is fixedly connected to the bottom of the heater 20, a first water pipe 23 is installed at the input end of the water pump 22, and a second water pipe 24 is installed at the output end of the water pump 22. The water inside the boiler 2 is electrically assisted heated to increase the heating speed, and the heated water can be output from the boiler 2 at a uniform speed.

[0043] Reference Figure 4 As shown, specifically, a water cooler 25 is installed on the other side of the shell 1, and a water cooling pipe 26 is installed on the output end of the water cooler 25 to reduce the internal temperature of the shell 1, avoid excessive heat accumulation, and increase the speed of maintenance by the staff.

[0044] Working principle of the utility model: before heating the double water-cooled smoke box vacuum boiler, water is first transported to the inside of the boiler 2 through the water pump 22, the first water pipe 23 and the second water pipe 24, and then the natural gas pipe is connected to the first gas pipe 4 through the connecting pipe 5, and the natural gas is passed between the boiler 2 and the outer tube 3. Then the base 7 ignites the natural gas between the outer shell 1 and the outer tube 3 to heat the outside of the boiler 2. At the same time, the water pump 22 further heats the water in the boiler 2 through the first water pipe 23. When the natural gas burns between the boiler 2 and the outer tube 3, the air pump 8 transports the oxygen in the oxygen tank 13 through the second gas pipe 10 through the air intake pipe 9 and the diffusion plate 11 to between the boiler 2 and the outer tube 3, so that the oxygen assists the natural gas to burn more fully. Then the heat generated by the natural gas and oxygen will be gathered in At the top of the outer tube 3, open the first butterfly valve 16 and use the fan 17 to suck the hot air into the bottom of the outer tube 3 through the gas collecting plate 15 and the outlet pipe 14, so that the hot air can be repeatedly circulated to the outside of the boiler 2. After the water inside the boiler 2 is heated, the hot water is discharged through the water pump 22, the first water pipe 23 and the second water pipe 24. When it is necessary to inspect the inside of the shell 1 and cool the boiler 2, first open the second butterfly valve 19. After the fan 17 sucks the smoke inside the outer tube 3 into the inside of the outlet pipe 14, close the butterfly valve at the bottom of the outlet pipe, and the flue gas containing heat will be discharged to the outside through the exhaust pipe 18. Finally, the water cooler 25 and the water cooling pipe 26 absorb heat from the outside of the boiler 2 and the outer tube 3, so that the temperature of the boiler 2 and the outer tube 3 is effectively reduced, which is convenient for inspecting the boiler 2 and the outer tube 3.
