10. A method of using the waste heat recovery type heat exchanger according to any one of claims 1 to 9, characterized in that: the use method of the waste heat recovery type heat exchanger comprises the following steps:
firstly, a bent air inlet pipe (12) is externally connected with a high-temperature hot air source, a liquid inlet pipe (14) is externally connected with a water source, a first valve (10) and an air compressor (7) are kept closed, high-temperature hot air enters a coil pipe assembly (19) through the bent air inlet pipe (12), then exchanges heat with water in a heat exchange shell (17), and is discharged through an exhaust straight pipe (9);
secondly, the water in the heat exchange shell (17) is heated by the high-temperature hot gas, the water in the heat exchange shell (17) is heated and boiled along with the continuous output of the high-temperature hot gas source, then the hot steam is discharged through the hot flow channel (5), and the high-temperature steam can be externally connected with a steam generator to store energy and can also be directly output for use;
thirdly, after the pipe coil assembly is used for a period of time, when the slag accumulated in the coil assembly (19) needs to be maintained and cleaned, the two second valves (13) can be closed, and then the first valve (10) is controlled to be opened;
fourthly, rotating the threaded ring (36) to stagger the position of the sealing door (34), then opening the sealing door (34), putting the bulge (23) of the brushing mechanism (2) into the sealing shell (31) upwards, closing the sealing door (34), and rotating and fixing the sealing door (34) by using the threaded ring (36);
fifthly, controlling the air compressor (7) to be started, and driving the cleaning mechanism (3) to enter the coil assembly (19) by high-pressure airflow generated by the air compressor (7);
sixthly, hanging more broken accumulated debris on the inner wall of the coil assembly (19) by the first rubber ring (21) in the advancing process until the broken accumulated debris is discharged from the discharge straight pipe (11);
seventhly, arranging a spiral blade (26) to enable the cleaning mechanism (3) to rotate and advance when moving in the coil pipe assembly (19), and brushing the cleaning hard bristles (25) with the inner wall surface of the coil pipe assembly (19) to scrape off dust;
and eighthly, repeating the third step to the seventh step, and effectively cleaning debris accumulated on the inner surface of the coil assembly (19) by using a plurality of wiping and brushing mechanisms (2).
