[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. The carbon black flue gas enters the smoke inlet pipe, and the flue gas passes through the dust removal device to separate the flue gas from the solid impurities. The flue gas enters the heat exchanger main body for heat exchange. When the solid impurities block the dust removal core, the staff uses tools to remove the bolts on the outside of the dust removal frame. The staff pulls the dust removal frame through the handle, and the dust removal frame drives the dust removal core to slide out of the smoke inlet pipe. Since the dust removal core is first snap-fitted into the snap-fitting groove of the dust removal frame through the sliding block and then fixed with bolts, the staff only needs to remove the bolts to replace the dust removal core. This device is not only convenient for replacing the dust removal core but also convenient for removing impurities from the carbon black flue gas.

[0014] 2. When the staff disassembles the smoke inlet pipe, the staff uses the rotary bolt valve to snap-fit on the top of the retaining bolt and rotates the rotary bolt valve to move the retaining bolt out of the receiving plate. The staff manually presses down the receiving plate, and the spring at the bottom of the receiving plate retracts into the limiting groove on the top of the base. Then, the retaining bolt is used to fix the receiving plate, which is convenient for the staff to disassemble the smoke inlet pipe. The receiving plate supports the bottom of the smoke inlet pipe through the spring, and a damping pad is installed inside the limiting groove to reduce the shock force adsorbed by the spring, which is convenient for the shock absorption of the heat exchanger main body.
