Abstract

The invention discloses a tubular condensation heat exchange system capable of realizing drop condensation. The tubular condensation heat exchange system comprises an air preheater, a dust collector,a desulfurization tower, a flue gas condenser, a chimney and a cooling fan. An outlet of the air preheater is communicated with an inlet of a heat exchange tube in the flue gas condenser sequentiallythrough the dust collector and the desulfurization tower, an outlet of the heat exchange tube in the flue gas condenser is communicated with an inlet of the chimney, an outlet of the cooling fan is communicated with an air inlet of the flue gas condenser, and an air outlet of the flue gas condenser is communicated with an external user end. Multiple scales are arranged on the inner wall of the heat exchange tube, and spiral fins are arranged on the outer wall of the heat exchange tube; and the condensation of flue gas moisture in the heat exchange system is mainly drop condensation, so that the heat exchange efficiency is higher, and the investment cost is lower.

Description

technical field [0001] The invention belongs to the technical field of energy saving and water saving, and relates to a tubular condensation heat exchange system capable of realizing bead condensation. Background technique [0002] As the environmental protection situation has become increasingly serious in recent years, more than 90% of thermal power plants in China have installed wet desulfurization systems. The temperature of the saturated wet flue gas at the chimney inlet of this kind of unit can reach about 54°C. Saturated wet smoke contains a lot of water, and after being discharged through the chimney, it will form a very obvious phenomenon of "white smoke" or even "chimney rain" at the chimney outlet. [0003] Many areas in our country are dry and water-short, but the entire unit needs to supplement a large amount of industrial water, which has caused difficulties in the operation of the power plant to a certain extent. It has become a hot topic to condense the wate...
