Abstract

The invention discloses a flue gas heat exchanger, which comprises a shell, an air inlet and an air outlet on the side of the shell, and a heat exchanging component inside the shell; the heat exchanging component includes: an upper surface penetrating through the shell; The heat exchange column on the lower surface; the heat exchange fin arranged on the heat exchange column in the circumferential direction; the air guide fin arranged on the heat exchange fin in an arc shape; it is arranged outside the heat exchange column and penetrates from the bottom of the heat exchange fin The air extraction groove of the heat exchange fin; the heat exchange material flow path arranged inside the heat exchange column and the heat exchange fin.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a flue gas heat exchanger. Background technique [0002] When the flue gas is discharged in the existing iron and steel enterprises, it is often necessary to use a flue gas heat exchanger to recover the waste heat of the flue gas. The waste heat recovery of flue gas mainly converts the heat carried by the flue gas into usable heat through a certain heat exchange method to save fuel. [0003] Existing flue gas heat exchangers use heat exchange fin-type heat exchange devices in use, and there are two drawbacks when applied to flue gas waste heat recovery. One is that long-term use will cause heat exchange fins. Dust accumulation affects the heat exchange efficiency; second, the circulation paths of the intake and exhaust gases are short, and the heat exchange effect is not ideal. SUMMARY OF THE INVENTION [0004] In order to solve the defects existing in the prior art, th...
