In order to avoid heat waste, the existing technology usually sets a heat recovery device at the gas outlet, and uses a heat recovery block with extremely high thermal conductivity to recover the heat in the waste gas before processing and discharging it. However, since the waste gas contains a lot of impurities and dust, the waste gas will impact the heat recovery block for a long time, which will form a layer of dirt on the heat recovery block, affecting the heat recovery effect; cleaning the heat recovery block is more troublesome, and it is often necessary to disassemble the heat recovery device, which is time-consuming and labor-intensive, and will also delay the heat recovery process.

[0025] Principle of the utility model

[0026] like Figure 1-2 In the normal use state diagram of this application, the object to be heated is placed in the placement slot 7 of the heat recovery block 6. The exhaust gas with a large amount of heat generated by the calcination of the waste carbon black by the furnace body 2 enters the heat recovery cylinder 8 through the connecting hole 13, and exchanges heat with the heat recovery block 6, thereby heating the object in the placement slot 7; after heat recovery, the exhaust gas enters the next treatment process through the treatment pipe 9, and finally is discharged after dust removal and purification.

[0027] Due to the long-term impact of the exhaust gas carrying impurities and dust, a layer of dirt will accumulate on the heat recovery block 6; when the heat recovery block 6 needs to be cleaned, the first electric telescopic rod 11 and the second electric telescopic rod 16 are first started to make the sealing cylinder 10 and the splash-proof cylinder 19 leave the slot 22 respectively; then the motor 14 is started to rotate the conversion plate 5, and the positions of the two heat recovery blocks 6 are exchanged, so that the old heat recovery block 6 corresponds to the cleaning cylinder 4, and the object to be heated is transferred to the new heat recovery block 6, so that the replacement of the heat recovery block 6 is completed quickly, and there is no need to disassemble the heat recovery cylinder 8, which is very convenient; directly Pour the cleaning agent from the top of the splash-proof cylinder 19 into the cleaning cylinder 4, then start the first electric telescopic rod 11 and the second electric telescopic rod 16 again, so that the sealing cylinder 10 and the splash-proof cylinder 19 are inserted into the card slot 22 again. At this time, the new heat recovery block 6 can continue to perform heat recovery work, and the old heat recovery block 6 that has been replaced is located in the cleaning cylinder 4 and the splash-proof cylinder 19. Start the cleaning pump 17 to clean the old heat recovery block 6. The waste water after cleaning is filtered by the filter 18 and then returned to the bottom of the cleaning cylinder 4 for recycling, avoiding the waste of cleaning agent. Finally, the waste water after cleaning flows out from the drain at the bottom of the cleaning cylinder 4. It should be noted that the filter 18 will inevitably become clogged after long-term use. At this time, a groove can be opened on the side wall of the cleaning cylinder 4 to take out the filter 18 for cleaning. This is a conventional operation of the prior art in the field and will not be described in detail in this application.
