Project overview:

At present, domestic flue gas desulphurization mostly adopts wet desulphurization process, which can reduce the smoke temperature to about 55℃. The flue gas at this temperature is directly discharged into the atmosphere and condensed into water droplets, forming "white smoke plume" under the refraction of sunlight, causing certain visual pollution to the surrounding residents.

Operating principle:

This technical route is to design and manufacture professional flue gas reheat equipment by using the excellent performance of new heat transfer materials. The equipment is different from other equipment, no circulation system, no external energy, the use of boiler flue gas heat, to heat the chimney smoke temperature, has the characteristics of simple structure, small investment, low operating cost.

Process flow:

A superconducting heat absorber is arranged between the dust collector and the desulphurization tower, and the high temperature heat here is transferred to the superconducting exothermer through superconducting, so as to heat the terminal flue gas. A condenser is added at the back end of the desulfurization tower to remove part of the moisture in the flue gas. The combination of "condensation + reheat" eliminates the white plume at the chimney outlet.
