Abstract

The invention discloses a fire coal smoke cyclone dedusting desulfurizer, which adopts liquid as adsorbent, and is used for the smoke purification treatment of a coal burning boiler. The fire coal smoke cyclone dedusting desulfurizer comprises a body, two cyclone plates, a first dustchamber, a second dustchamber, a water bath dustchamber, a desulfuration chamber, a purification chamber, an alkali liquor spraying device, a water spraying device, an activated carbon desulfurization ring, a solution mixing pump, a solenoid valve, a circulation alkali tank, a stirrer, a solution transfer pump, a filter tank, a slag scraping machine, a transfer trolley and the like. Two-stage cyclone dedusting, solid-gas separation in the water bath, alkali liquor spraying, liquid adsorption desulfuration and wet-type purification are adopted by aiming at the smoke of an oil burning boiler, not only does the emission reach the environmental-friendly standard, but also both the clear water and the alkali liquor are recycled, so the double circulation of lye and alkali liquor and the automatic slag discharge are realized.

Description

technical field [0001] The invention relates to a coal-fired boiler flue gas purification device, in particular to a coal-fired flue gas cyclone dust removal and desulfurization device using liquid as an adsorbent. Background technique [0002] Sulfur dioxide, nitrogen oxides and dust in the waste gas produced by coal-fired / heavy oil boilers have caused serious pollution to the environment. Nitrogen oxides are major pollutants that are difficult to control. Many small and medium-sized enterprises launched in the 1990s in our country, such as textile printing and dyeing enterprises, used a large number of oil-fired boilers in production. The soot, sulfur dioxide and nitrogen oxides produced by the oil-fired boiler during the production process have caused environmental pollution to the surrounding areas. According to environmental protection requirements, the polluted equipment, especially the flue gas produced by the oil-fired boiler, must be treated. Contents of the in...
