The contradiction between the problem of garbage pollution and the lack of corresponding garbage treatment equipment has gradually emerged. The problem of garbage treatment has become a key issue for improving people's living environment. At present, domestic garbage is mainly incinerated. A large amount of high-temperature flue gas will be generated when garbage is incinerated by a large-scale incinerator. At this time, a condenser is needed to perform heat exchange treatment on the high-temperature flue gas.

[0003] The authorized announcement number CN 213454377 U discloses a combined condenser, which includes a base. The top of the base is fixedly installed with a fuselage.
