[0039] First, the water pump 301 starts working. The function of the water pump 301 is to transport the water collected in the collection hopper 103 through its output end to the heating high-temperature furnace 303 at the bottom of the drying box 100. The water sent by the water pump 301 is quickly heated to a high temperature, causing it to evaporate into steam. After the steam is generated in the heating high-temperature furnace 303, it is discharged through its gas outlet and enters the vacuum pump 304 through the connecting pipe 1 305 connected to the vacuum pump 304. The vacuum pump 304 accelerates the flow of steam. The vacuum pump 304 enters the diversion housing 501 through the connecting pipe 2 503. The two gas pipes 502 are respectively connected to the two heating rollers 106 in the drying box 100, so that the heating rollers 106 further dry the paper pulp and reduce water waste.
