Abstract

A device for quicklime digestion, dedusting and sewage sludge treatment comprises a quicklime digester (1), a water bath deduster (Q1) and a sewage treatment device, wherein the sewage treatment device comprises a sewage pool, a stirring device arranged on the sewage pool, a sewage pump and a sludge dehydrator. The quicklime digester is provided with a sealing dedusting cover (6) with a dust collecting outer port (601). The water bath deduster (Q1) is communicated with the dust collecting outer port (601) of the digester (1) through a dedusting pipeline (Q4), and the bottom of the water bath deduster (Q1) is provided with a dedusting sewage pipe communicated with the sewage pool. A method for quicklime digestion, dedusting and sewage sludge treatment is further provided.

Description

technical field [0001] The invention relates to the field of quicklime digestion in iron and steel sintering plants, in particular to a high-efficiency quicklime digestion, dust removal and sewage treatment system. It mainly solves the problems of quicklime digestion and dust removal and sewage pollution to the environment. Background technique [0002] With the development of modern industry and the improvement of people's quality of life, the requirements for environmental protection are getting higher and higher. Safe production and clean production have become the symbol of modern enterprise civilization. [0003] Quicklime, also known as lime, is mainly composed of calcium oxide, chemical formula CaO, relative molecular mass 56.08; white block or powder, cubic crystal system, often because of containing MgO, Al in industrial products 2 o 3 and Fe 2 o 3 It is dark gray, light yellow or brown due to other impurities; relative density is 3.25-3.38g / cm3, true density is...
