The specific working principle is as follows:

when the waste heat boiler starts to work, high-temperature flue gas enters the boiler main body 1 from the flue gas inlet 2 and flows to the chimney 3 through the boiler main body 1; when high-temperature flue gas flows in the boiler main body 1, the high-temperature flue gas passes through the fin pipes 14 which are distributed in a serpentine shape densely, the heat transfer area of the fin pipes 14 is enlarged through surface welding of the fins, and the high-temperature flue gas has a strong heat transfer effect, at the moment, the base 4 is started to enable water flow to continuously flow into the temperature control device 41 from the water inlet pipe 42, then the water flow reaches the flow dividing valve 4127, and the flow dividing valve 4127 enables the water flow to flow upwards along the flow dividing pipe 4124 and then enter the temperature control flow path.

When the temperature needs to be reduced, the driving motor 411 is started to drive the rotary valve I4121 and the rotary valve II 4129 to rotate, so that the guide pipe 4122 is respectively aligned and connected with the condensation water pipe 43 and the steam outlet pipe I414, then water flows upwards into the steam outlet pipe I414 through the guide pipe 4122, and is vaporized in the steam outlet pipe I414 under the heat transfer effect of high-temperature flue gas, and steam generated after vaporization finally reaches the steam dividing drum III 13 and is guided to the outside by the steam dividing drum III 13 for use according to the requirements; when the steam needs to be further cooled, the base 4 can be started to enable condensed water to flow into the temperature control device 41 along the condensed water pipe 43, flow into the flow dividing valve 4127 through the flow guiding pipe 4122 and the flow dividing pipe 4124 in the temperature control device 41, and then flow into the first steam outlet pipe 414 along the flow dividing pipe 4124 through the flow dividing valve 4127; because the temperature of the condensed water is low, the inflow of a large amount of condensed water can reduce the overall temperature of the first steam outlet pipe 414, so that the temperature of steam flowing out of the first steam outlet pipe 414 is reduced.

Similarly, when the temperature needs to be increased, the driving motor 411 is started to drive the rotary valve I4121 and the rotary valve II 4129 to rotate, so that the guide pipe 4122 is respectively aligned and connected with the steam inlet pipe 413 and the steam outlet pipe II 415, water flows upwards along the flow dividing pipe 4124, flows into the steam outlet pipe II 415 after passing through the guide pipe 4122, is gasified into steam in the steam outlet pipe II 415 and flows into the steam dividing drum II 12, then the steam continuously flows in the steam dividing drum II 12 under pressure, flows out of the steam dividing drum II 12, flows into the steam dividing drum I11 along the fin pipe 14, and finally reaches the steam dividing drum I11 for use according to requirements; when further heating is required, the second steam dividing drum 12 is started to enable a part of steam to flow to the temperature control device 41 along the steam inlet pipe 413, then flow to the flow dividing valve 4127 through the flow guiding pipe 4122 and the flow dividing pipe 4124, and flow continues to flow upwards along the flow dividing pipe 4124 through the flow dividing valve 4127, at the moment, steam encounters the entering water flow, so that the water flow is heated, the initial temperature of the water flow entering the second steam outlet pipe 415 is further increased, heat consumption during water flow vaporization is reduced, and the temperature of the steam obtained in the first steam dividing drum 11 is further increased.

Compared with the problem that the steam temperature cannot be controlled in the prior art, the utility model enables the condensed water to continuously flow into the steam outlet pipe through the built-in condensate pipe and the diverter valve so as to reduce the temperature, and realizes the cooling effect on the steam temperature in a smaller space; the steam obtained through primary heating flows back into the temperature control device again through the built-in steam inlet pipe and the flow dividing valve, so that the steam is utilized to heat the water flow, the initial temperature of the water flow is higher, the steam with higher temperature is obtained under the condition that the external temperature is unchanged, and the heating effect on the steam temperature is realized in a smaller space; through the structural design of the turntable switching type, the occupied space of the device is saved, and the error connection among a plurality of pipelines is avoided.
