[0025] Specifically, because the cavity 19 is wrapped to the water tank 20, when the waste heat enters the cavity 19 through the connecting pipe 2, the water in the water tank 20 is preliminarily heated, and then under the action of the heat pipe 21, the water in the water tank 20 can also be heated, so that the waste heat can be more fully utilized. Improving energy utilization rate means that under the same energy consumption, more useful work or output can be generated. The filter plate 12 can filter the exhaust gas, the inlet pipe 5 can add water to the water tank 20, the outlet pipe 6 can discharge the water in the water tank 20, the air outlet pipe 4 can discharge the heat source, and the smoke pipe 7 can discharge the flue gas.

[0026] Referring to Figure 1 、 Figure 3 and Figure 4 , the pull rod 14 in the inner wall of the fixed block 13, the left end of the pull rod 14 is fixedly connected with the clamp head 17, the outer wall of the pull rod 14 is provided with the spring 18, the left side of the outer wall of the pull rod 14 is fixedly connected with the limiting sheet two 16, the right side of the outer wall of the pull rod 14 is fixedly connected with the limiting sheet one 15, one end of the spring 18 is arranged at the right end of the limiting sheet two 16, the other end of the spring 18 is arranged at the left end of the limiting sheet one 15, the inner wall of the fixed plate 8 is provided with the mortise slot 10, the outer wall of the filter plate 12 is fixedly connected with the tenon 9, the tenon 9 is slidingly connected with the inner wall of the mortise slot 10, the top of the water tank 20 is fixedly connected with the fixed column 22, the fixed column 22 is fixedly connected with the inner wall top side of the boiler main body 1, the left end bottom side of the boiler main body 1 is fixedly connected with the connecting pipe 2, the connecting pipe 2 is fixedly connected with the right end top side of the TO furnace main body 3, the top and bottom ends of the fixed plate 8 are fixedly connected with the rubber ring 11;

[0027] Specifically, when the filter plate 12 is used for a period of time, the pull rod 14 is rotated to drive the clamping head 17 to rotate, so that the clamping head 17 is disengaged from the smoke outlet pipe 7, then the pull rod 14 is pulled to the right to drive the clamping head 17 to move out of the clamping head 17, then the filter plate 12 is removed from the smoke outlet pipe 7 by rotating the fixed plate 8, and then the filter plate 12 is disassembled from the fixed plate 8 through the tenon strip 9 and the mortise groove 10, so that the filter plate 12 is cleaned or replaced to ensure the filtering effect. The pull rod 14 can be rotated together with the spring 18 through the limiting piece two 16 and the limiting piece one 15. The residual heat in the TO furnace body 3 can be moved to the cavity 19 in the boiler body 1 through the connecting pipe 2. The inlet pipe 5 and the outlet pipe 6 are provided with valves.

[0028] Working principle: The residual heat in the TO furnace body 3 enters the cavity 19 in the inner wall of the boiler body 1 through the connecting pipe 2. Since the cavity 19 wraps the water tank 20, the residual heat exchanges heat with the water in the water tank 20, so that the water is preliminarily heated, and at the same time, the residual heat in the cavity 19 also enters the plurality of heat conducting pipes 21 connected thereto. The heat conducting pipes 21 are distributed in the inner wall of the boiler body 1, which further transfers the residual heat to the water in the water tank 20. The water vapor generated by heating the water is discharged to a suitable position through the outlet pipe 4. When the filter plate 12 is used for a period of time and needs to be cleaned or replaced, the pull rod 14 is first rotated, the pull rod 14 drives the clamping head 17 to rotate, so that the clamping head 17 is disengaged from the clamping state of the smoke outlet pipe 7. Then, the pull rod 14 is pulled to the right, and the clamping head 17 is moved out of the smoke outlet pipe 7. At this time, the fixed plate 8 is rotated, and since the fixed plate 8 is slidably connected to the tenon strip 9 of the filter plate 12 through the mortise groove 10, the filter plate 12 can be removed from the smoke outlet pipe 7. Then, the filter plate 12 is disassembled from the fixed plate 8 along the mortise groove 10, so that the filter plate 12 is conveniently cleaned or replaced.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
