Abstract

The invention provides a flue gas recovery heat exchange device for an acid regeneration unit. The flue gas recovery heat exchange device comprises a barrel, a lower seal head is arranged at the bottom of the barrel, an upper seal head is arranged at the top of the barrel, and a cover plate is arranged above the upper seal head; and a plurality of heat exchange blocks are arranged inside the barrel, and gaskets are arranged among the heat exchange blocks. According to the flue gas recovery heat exchange device for the acid regeneration unit, effective heat exchange is conducted on flue gas by arranging the heat exchange blocks, meanwhile, two times of heat exchange is conducted on the flue gas through cooling water and combustion-supporting gas, steam in the flue gas is converted into condensate water with a large number of chloride ions, the chloride ions are effectively recovered, the air pollution is prevented, PM2.5 is reduced, the smoke is more environment-friendly, meanwhile, the use of equipment such as a motor is reduced, and the electric energy is saved.

Description

technical field [0001] The invention belongs to the field of acid regeneration units, and in particular relates to a flue gas recovery heat exchange device and a heat exchange method for acid regeneration units. Background technique [0002] With the rapid economic and social development and the continuous advancement of urbanization, environmental protection and water shortage have become two important factors restricting the sustainable development of social economy. [0003] Especially in the iron and steel field, the direct emission of high-temperature flue gas will have a great negative impact on environmental protection. [0004] However, the cost of flue gas purification in the prior art is generally high, which greatly affects the purification and reuse of flue gas, and at the same time, there is no effective means for the purification and utilization of high-temperature flue gas. Contents of the invention [0005] In view of this, the present invention aims to ov...
