6. A method of using the heat recovery heat exchanger of claim 5, wherein: the using method of the waste heat recovery type heat exchanger comprises the following steps:
the first step, a bent air inlet pipe (12) is externally connected with a high-temperature 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 air enters a coil pipe assembly (19) through the bent air inlet pipe (12) and then exchanges heat with water in a heat exchange shell (17), and the water is discharged from an exhaust straight pipe (9);
the second step, the water in the heat exchange shell (17) is heated by the high-temperature hot gas, along with the continuous output of the high-temperature hot gas source, the water in the heat exchange shell (17) is heated and boiled, 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 coil pipe assembly is used for a period of time, when the slag stored in the coil pipe assembly (19) needs maintenance and cleaning, 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), upwards placing the bulge (23) of the brushing mechanism (2) into the sealing shell (31), closing the sealing door (34), and rotationally fixing the sealing door (34) by using the threaded ring (36);
fifthly, controlling the air compressor (7) to be started, and enabling high-pressure air flow generated by the air compressor (7) to push the cleaning mechanism (3) to enter the coil pipe assembly (19);
sixthly, hanging more broken and accumulated scraps on the inner wall of the coil pipe assembly (19) in the advancing process of the first rubber ring (21) until the scraps are discharged from the discharge straight pipe (11);
seventh, the spiral blade (26) is arranged to enable the cleaning mechanism (3) to rotationally advance when moving into the coil pipe assembly (19), and the cleaning hard brush hair (25) and the inner wall surface of the coil pipe assembly (19) are brushed, so that dust is scraped off;
eighth, repeating the third through seventh steps, the inner surface of the coil assembly (19) can be effectively cleaned to accumulate debris using a plurality of brushing mechanisms (2).
