Abstract

The invention belongs to the technical field of coal-fired flue gas purification, and in particular relates to a coal-fired flue gas powder adsorbent injection mercury removal device, which includes an adsorbent feeding part, an adsorbent powder conveying part and an adsorbent distribution injection part, wherein, The adsorbent feeding part includes a storage tank and a screw feeder; the adsorbent powder conveying part includes a frequency conversion feeder, a fan and an injector, and the ejector material is connected to the material conveying pipeline; The powder distributor is connected to several injection pipelines, and the injection pipeline is equipped with a spray gun and an intelligent flow control system. The invention can automatically and quickly adjust the dosing ratio of the powder adsorbent according to the mercury content in the flue gas, avoiding excessive or insufficient addition of the powder adsorbent, improving the effect of spraying mercury removal, reducing the waste of the powder adsorbent, and improving the The use efficiency of powder adsorbent reduces the cost of mercury removal.

Description

technical field [0001] The invention belongs to the technical field of coal-fired flue gas purification, and in particular relates to a coal-fired flue gas powder adsorbent injection mercury removal device. Background technique [0002] With the progress of society and the enhancement of people's awareness of environmental protection, the control of mercury emissions in coal-fired flue gas has gradually become an important environmental protection issue. my country is the country that burns the most coal, and the problem of mercury pollution is very serious. According to statistics, the total amount of mercury emitted into the atmosphere in the world is about 5,000 tons per year, of which 4,000 tons is the result of man-made. my country is a country with more coal and less oil. The resource structure determines that my country is a country with a large coal consumption. 75%. [0003] At present, my country is one of the areas with the most serious mercury pollution in the w...
