Please refer to Fig. 1-Fig. 8, on the basis of embodiment 1, the present invention provides a kind of technical solution: a kind of use method of the spray drying tower that waste heat can be recycled, step 1: put drying tower 2 on the base 1 The outer support frame 3 is fixed to work, and the heat is transferred to the inside of the transfer box 5 through the air duct 4 during work, and is transported to the inside of the sealed cylinder 64 along with the multiple connecting pipes 7 on the transfer box 5, so that it is in the airtight The inside of the sealing cylinder 64 is filtered through the filter frame 655;

Step 2: Use the heat conduction column 653 inside the sealed cylinder 64 to transfer heat to the heat exchanger 651, and after the heat is processed by the transducer, it is transported to the interior of the storage cylinder 652 for storage. When the gas circulates, the filter frame 655 follows The blowing of the gas is inclined, the assembly pipe 82 is fixed by the abutment frame 85 inside the sleeve 81, and the assembly arc plate 83 cooperates with the stabilizing plate 84 to install the sleeve 81 on the heat conduction column 653;

Step 3: With the gas circulating inside the sealed cylinder 64, the blowing collision block 664 moves on the reset rod 663 to knock on the contact position parts, and the circulation pipe frame 661 passes through the protective frame 662 against the gas inside the sealed cylinder 64. Carry out circulating flow, and use the barrier plate 95 to protect the heat conduction column 653 on the clamping arc plate 92, and at the same time separate the inner space of the sealed cylinder 64;

Step 4: The auxiliary card frame 91 cooperates with the contact increasing frame 93 to limit the barrier plate 95, so that the clamping arc plate 92 is supported by the clamping plate 94 and the auxiliary card frame 91, and the barrier plate 95 and the protective frame 662 are used The active space between the sealed cylinders 64 collects the impurities contained in the gas;

Step 5: As the temperature of the air inside the sealed cylinder 64 drops, it is transferred to the inside of the filter cylinder 71 through the drainage tube 632, and the filter cylinder is tightened by the abutment column 633 inside the control box 62 to tighten the guide housing 634 71 is fixed, the sealing sleeve 75 inside the filter cylinder 71 cooperates with the drainage tube 632 to carry out the sealing and drainage of the connection position;

Step 6: Push the stretch rod 74 to elongate the gas inside the filter cylinder 71, so that the stretch rod 74 is stretched and push the cleaning ring 72 to clean the inside of the filter cylinder 71, and the blocking block 73 is filtered The cylinder 71 is flipped and opened, so that some impurities directly enter the opening position of the blocking block 73 to drop, and the gas inside the filter cylinder 71 enters the interior of the drying tower 2 through the return pipe 61 to blow it.
