Two-stage binary flue gas treatment system

Abstract

The invention discloses a two-stage binary flue gas treatment system, comprising: heat exchange equipment; dust removal equipment; a desulfurization tower, which includes a first tower body, a first flue gas uniform distribution device and a first spraying device, Consists of a first main body, a first enlarged diameter section and a first lower part; the first smoke uniform distribution device includes a first upper plate and a first lower plate, the top wall of the first upper plate is protrudingly provided with a plurality of The first jet column, the extension line of the outermost first jet column converges on the axis of the first tower body and converges outside the first tower body; the absorption tower. The invention organically combines the binary removal technology, greatly reduces the operating cost of environmental protection, and truly realizes the continuous operation of clean, environment-friendly and energy-saving. The invention improves the structure of the desulfurization tower and the absorption tower, improves the first smoke uniform distribution device in the desulfurization tower and the second smoke uniform distribution device in the absorption tower, and improves the desulfurization efficiency of the desulfurization tower and the absorption tower.

Description

technical field [0001] The invention relates to the technical field of rotary kiln tail gas treatment, in particular to a two-stage binary flue gas treatment system. Background technique [0002] The main components of untreated rotary kiln tail gas are SO2, H2S, NOx, NH3, sulfuric acid mist, dust, etc. The content of SO2 and H2S in it far exceeds the national discharge standard and seriously pollutes the environment. Therefore, it must be treated and discharged after meeting the environmental protection discharge standard. At present, desulfurization towers and absorption towers are often used to remove sulfur dioxide and hydrogen sulfide contained in the tail gas. However, the removal efficiency of the existing desulfurization towers and absorption towers still needs to be improved, which leads to the flue gas in the entire flue gas treatment system. There is still room for improvement in the gas treatment effect. Contents of the invention [0003] An object of the pre...
