The principle of the structure is as follows: dirty hot air (hereinafter referred to as dirty air) from each drying room of the setting machine 3 enters the hot air processing device 2 through a pipeline with a heat preservation function and is extracted by a fan 25 arranged on the side surface of the hot air processing device 2. When the dirty air passes through the hot air processing device 2, the liquid heat carrier in the hot air processing device 2 in the hot air absorbs and evaporates into gas, and the gas is discharged from the gas heat carrier outlet 21.

The heat carrier gas evaporated from the hot air processing device 2 moves from the gaseous heat carrier inlet 11 to the radiator 1 without power through the insulated first pipeline 41, releases heat, condenses into liquid and flows to the liquid heat carrier inlet 22 on the top exhaust gas outlet side of the hot air processing device 2 through the second pipeline 42. Two rows of first heat carrier heat exchange tubes 261 on the inlet diameter preheat liquid heat carriers, shunt the liquid heat carriers to a second heat carrier heat exchange tube 262 of the hot air treatment device 2 from a shunt tube on the side surface of the bottom of the hot air treatment device 2, absorb heat, evaporate the liquid heat carriers into a gas state, and gather the gas state to the hot air treatment device 2 to take away heat for the next circulation. The reciprocating circulation enables the heat in the hot polluted air of the setting machine 3 to be continuously transported to the radiator 1. Because the heat-releasing radiator 1 is not adjacent to the hot dirty air of the setting machine 3, any leakage pollution of the dirty air can not generate secondary pollution to the radiator 1. The generated preheating is more clean and environment-friendly.

The heat carrier heat exchange tube of the hot air treatment device 2 is provided with a spraying (namely a spraying water pipeline) and dirt scraper cleaning device (namely a scraper driving device, a scraper 292 and a supporting seat). The upper header pipe 271 is connected to the branch shower pipes 273, and 9 straight shower pipes 272 are connected thereto. A fan atomizing nozzle 2721 is installed on the shower water straight pipe 272. The spray water straight tubes 272 are evenly distributed among the plurality of heat carrier heat exchange tubes. The hot spray water reaches the atomizing nozzle 2721 through the spray water header pipe 271, the spray water branch pipes 273 and the spray water straight pipe 272, and is uniformly sprayed on the outer walls of all the heat carrier heat exchange pipes. The adherent contaminants on the heat carrier heat exchange tubes flow with the downwardly flowing shower water into a waste bin 297 located at the bottom of the heat carrier heat exchange tubes. The shower water flows into the hot air treatment device 2 through the overflow port and is discharged through a shower drain pipe (not shown) at the bottom. The trash can 297 is periodically cleaned manually.

A driving chain wheel 283 and 4 driven chain wheels 284 are arranged at the four corners of the hot air processing device 2, and a bearing seat 285 is fixedly connected below each chain wheel. The lead screw on the upper part of the bearing is provided with a chain wheel. The 4 driven sprockets 284 are driven to rotate simultaneously by a screw drive motor 281 via a chain 282. A screw 291 is mounted under each bearing seat 285, a copper nut 294 is mounted on each screw 291, and the porous wiper 292 is bolted to the copper nut 294. As the screw 291 rotates, the scraper 292 reciprocates in the heat pipe axis direction of the hot air processing apparatus 2 together with the copper nut 294. After the spraying operation is carried out for a period of time, part of stubborn dirt is still attached to the outer wall of the heat exchange tube of the heat carrier, and although water flow is leaked, moistened and softened, the water flow does not rush down. The screw driving motor 281 is activated to move the scraper 292 downward, and dirt is forcibly scraped and carried away by the shower water. A photoelectric switch (not shown) is arranged on the upper part of one of the screws 291, so that the rotation number of the screw can be calculated, and the scraper reaches the bottom after reaching a certain value. At this time, the control system makes the motor rotate reversely, and the scraper 292 moves upwards to the highest position to stop, thereby completing a dirt scraping cycle.
