The working principle of the specific embodiment is as follows: when the boiler body 31 is used, smoke generated by the boiler body 31 enters the exhaust pipe 3 through the smoke pipe body 1, water is pumped into the casting pipe 4 through an external water pump, the smoke entering the exhaust pipe 3 heats the water inside the casting pipe 4, after the water is heated, the first control valve 5 on the upper side is opened, hot water is discharged, steam generated in the heating process of the water enters the first steam pipe 6 and then enters the turbine steam generator 8 through the first steam pipe 6, when the steam is generated inside the boiler body 31, the air suction pump 9 is started, the steam in the boiler body 31 is pumped into the second steam pipe 10 through the air suction pump 9, then enters the first steam pipe 6 and finally enters the turbine steam generator 8, energy conversion is further performed through the turbine steam generator 8, dust contained in the smoke inside the exhaust pipe 3 is filtered through the filter plate 14, fall into in dust collecting box 13, and then collect through dust collecting box 13, and the exhaust flue gas filters via activated carbon layer 17 earlier, filters a period of back, upwards pulls out fixed frame 15 through handle 18, then clears up this activated carbon layer 17 of fixed frame 15 inside, more changes new activated carbon layer 17, and then conveniently filters the flue gas.

Compared with the prior art, the beneficial effects of the embodiment are as follows:

1. after the water in the cast pipe 4 is heated by the flue gas, the hot water is discharged, the steam generated in the heating process of the water enters the turbine steam generator 8, and the steam is converted into electric energy through the turbine steam generator 8, so that the energy-saving effect is achieved;

2. an air suction pump 9 is fixed on the upper side wall of the boiler body 31, the air suction pump 9 collects water vapor generated in the boiler body 31, the water vapor is discharged into the first steam pipe 6 through the second steam pipe 10, and finally enters the turbine steam generator 8, so that the energy maximization is achieved;

3. a filter plate 14 is arranged on the lower side inside the discharge pipe 3, the filter plate 14 filters the flue gas, and dust contained in the flue gas falls into a dust collecting box 13, so that the dust is prevented from being adsorbed on the outer side wall of the casting pipe 4, the heat absorption effect of the casting pipe 4 is not influenced, and the heating efficiency is improved;

4. the front side and the rear side of the dust collection box 13 slide on the slide rails 24 at the front side and the rear side through the slide blocks 23 respectively, so that the stability of the dust collection box 13 can be improved;

5. dust collection box 13 left side sets up recess 26, and then makes things convenient for the drawing of dust collection box 13 to send, and is equipped with two-way slide wedge 29 in the cavity 27 of recess 26 downside, and two-way slide wedge 29 can reciprocate, and then can block recess 26, avoids the dust to waft from recess 26, has reduced the pollution of environment.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
