DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0020] like Figure 1-5 As shown, a waste incinerator 1 flue gas waste heat conversion device includes an incinerator 1, characterized in that: a connecting pipe 5 is provided at the upper end opening of the incinerator 1, the upper end of the connecting pipe 5 is connected to a conversion tube 2, one end of the conversion tube 2 is provided with a first branch pipe 3, one end of the first branch pipe 3 is provided with a bracket 21, a smoke removal structure is provided on the bracket 21, the smoke removal structure includes a rotating drum 7, a plurality of wiping strips 8 are evenly provided on the rotating drum 7, a smoke outlet adjustment structure is provided on the connecting pipe 5, the smoke outlet adjustment structure includes a first rotating plate 19 and a second rotating plate 20 rotating in opposite directions, and a circulating water pipe 6 is provided on the conversion tube 2.

[0021] When the utility model is in use, garbage is placed in the incinerator 1 for incineration, and the generated smoke will carry a large amount of heat. According to the amount of smoke in the incinerator 1, the smoke outlet adjustment structure is controlled to work, and the first rotating plate 19 and the second rotating plate 20 rotate towards each other, thereby adjusting the size of the smoke outlet of the pipe 5. When the amount of garbage incineration in the incinerator 1 is small, the first rotating plate 19 and the second rotating plate 20 can be rotated to reduce the smoke outlet of the pipe 5. When the amount of garbage incineration in the incinerator 1 is large, the first rotating plate 19 and the second rotating plate 20 can be rotated to a vertically parallel state to avoid To prevent flue gas from accumulating in the incinerator 1, the flue gas enters the conversion tube 2 through the connecting pipe 5. Since a water pipe 6 is provided in the conversion tube 2, when water flows through the water pipe 6, the waste heat of the flue gas in the conversion tube 2 is recovered and utilized. At the same time, the smoke dust removal structure is controlled to work. After the flue gas enters the conversion tube 2, since a lot of smoke dust will be mixed in the smoke, in order to prevent a large amount of smoke dust from adhering to the walls of the conversion tube 2 and the water pipe 6 and affecting the heat transfer efficiency, the rotating drum 7 can be controlled to rotate, and the rotating drum 7 drives a number of wiping strips 8 to swing in a circle, and the wiping strips 8 are used to shake off the smoke dust adhering to the conversion tube 2 and the water pipe 6.

[0022] The smoke outlet adjustment structure also includes a worm 15 rotatably connected to the connecting pipe 5, the worm 15 is engaged with a worm wheel 16, the worm wheel 16 is coaxially fixedly connected to a first gear 17, the first gear 17 is engaged with a second gear 18, the second gear 18 is coaxially fixedly connected to the second rotating plate 20, and the first gear 17 is coaxially fixedly connected to the first rotating plate 19.

[0023] like Figure 1 and 4 As shown, a rotating handle 14 is provided at one end of the worm 15, which drives the worm 15 to rotate through the rotating handle 14, and the worm 15 drives the worm wheel 16 to rotate, and the worm wheel 16 drives the first gear 17 to rotate, and the first gear 17 drives the second gear 18 to rotate. Since the first gear 17 and the second gear 18 are engaged, the first rotating plate 19 and the second rotating plate 20 rotate towards each other, thereby adjusting the size of the smoke outlet of the connecting pipe 5, changing the amount of smoke output, and then adjusting the amount of smoke output according to the amount of garbage incineration, thereby improving the utilization rate of waste heat in the flue gas.

[0024] The smoke and dust removal structure also includes a bracket 21 fixedly connected to the second branch pipe 4, one end of the bracket 21 is fixedly connected to the motor 12, the output end of the motor 12 is fixedly connected to the first pulley 11, the first pulley 11 is connected to the second pulley 10, the second pulley 10 is fixedly connected to the rotating rod 9, and the rotating drum 7 is provided on the rotating rod 9.

[0025] like Figure 3 As shown, the output end of the motor 12 drives the first pulley 11 to rotate, the first pulley 11 drives the second pulley 10 to rotate, the second pulley 10 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the rotating drum 7 to rotate during the rotation process, and the rotating drum 7 drives the wiping strip 8 to swing in a circle to remove the dust adhering to the inner walls of the water pipe 6 and the conversion tube 2.

[0026] The output end of the motor 12 is also fixedly connected to a blower fan 13 , and the air outlet of the blower fan 13 is directed toward one end of the wiping strip 8 , and the wiping strip 8 is located at the upper end of the connecting pipe 5 .

[0027] like Figure 3 and 5 As shown, since the flue gas rises into the connecting pipe 5, a lot of smoke and dust will be formed on the conversion tube 2 near the connecting pipe 5. Therefore, the smoke and dust on the conversion tube 2 can be cleaned by using the wiping strip 8. The output end of the motor 12 drives the blowing fan 13 to rotate, and the blowing fan 13 is used to discharge the smoke and dust to prevent the smoke and dust from being adsorbed on the water pipe 6 and affecting the heat transfer performance of the water pipe 6. At the same time, the blowing of the blowing fan 13 will cause the pressure at the upper end of the connecting pipe 5 to decrease. Due to the pressure difference, the smoke in the incinerator 1 will be attracted to enter the conversion tube 2, thereby improving the utilization rate of the waste heat of the smoke in the conversion tube 2.

[0028] The inner wall of the conversion tube 2 is provided with a plurality of receiving grooves, in which the water pipe 6 is arranged, and the interface and outlet of the water pipe 6 are located on the same side.

[0029] like Figure 1 and 5 As shown, the storage groove is used to fix the water pipe 6. Cold water is injected into the water pipe 6 through the interface of the water pipe 6. After the cold water in the water pipe 6 conducts the heat in the flue gas, hot water flows out from the outlet. The hot water is used in daily life to realize the recovery and utilization of the waste heat of the flue gas.

[0030] The working process of the present invention is as follows: when the present invention is in use, garbage is placed in the incinerator 1 for incineration, and the generated smoke will carry a large amount of heat. According to the amount of smoke in the incinerator 1, the worm 15 is driven to rotate by the rotating handle 14, the worm 15 drives the worm wheel 16 to rotate, the worm wheel 16 drives the first gear 17 to rotate, and the first gear 17 drives the second gear 18 to rotate. Since the first gear 17 and the second gear 18 are meshed, the first rotating plate 19 and the second rotating plate 20 rotate in opposite directions, thereby connecting the smoke outlet of the pipe 5. The size can be adjusted. When the amount of garbage incineration in the incinerator 1 is small, the first rotating plate 19 and the second rotating plate 20 can be rotated, the smoke outlet of the connecting pipe 5 can be adjusted to be small, and the smoke slowly enters the conversion tube 2. When the amount of garbage incineration in the incinerator 1 is large, the first rotating plate 19 and the second rotating plate 20 can be rotated to a vertically parallel state to avoid smoke accumulation in the incinerator 1. The smoke enters the conversion tube 2 through the connecting pipe 5. Since a water pipe 6 is provided in the conversion tube 2, when water flows through the water pipe 6, the waste heat of the smoke in the conversion tube 2 is recovered and utilized.

[0031] At the same time, after the flue gas enters the conversion tube 2, since there will be a lot of smoke dust mixed in the flue gas, in order to prevent the smoke dust from adhering to the walls of the conversion tube 2 and the water pipe 6 and affecting the heat transfer efficiency, the output end of the motor 12 drives the first pulley 11 to rotate, the first pulley 11 drives the second pulley 10 to rotate, the second pulley 10 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the rotating drum 7 to rotate during the rotation process, and the rotating drum 7 drives the wiping strip 8 to swing in a circle to remove the dust adhering to the inner walls of the water pipe 6 and the conversion tube 2. At the same time, the output end of the motor 12 drives the blowing fan 13 to rotate, and the blowing fan 13 is used to discharge the smoke dust. At the same time, due to the blowing of the blowing fan 13, the pressure at the upper end of the connecting pipe 5 will be reduced. Due to the pressure difference, the smoke in the incinerator 1 will be attracted to enter the conversion tube 2, thereby improving the utilization rate of the waste heat of the smoke in the conversion tube 2.
