Abstract

The invention provides a method for realizing zero emission of carbon dioxide by former body removal of respirable particulate matter from fired coal. The method is characterized in that a bag type dust collector is used for filtering and removing respirable particulate matter from coal-fire flue gas, and comprises the following steps: the flue gas is input into a first fluidized bed reactor, with potassium bicarbonate produced by the reaction between carbon dioxide and potassium carbonate; the flue gas is separated by a first cyclone separator into purified flue gas and potassium bicarbonate, the purified flue gas is sent out, potassium bicarbonate is input into a second fluidized bed reactor to be subjected to reaction which can produce potassium carbonate and carbon dioxide, potassium carbonate is sent back to the first fluidized bed reactor; and carbon dioxide is separated by a second cyclone separator into purified gas and other isolation, the purified gas is sent out, and the other isolation is sent back to the second fluidized bed reactor. The invention also provides a device for realizing zero emission of carbon dioxide by former body removal of respirable particulate matter from fired coal. The invention has the advantages of reducing the emission of greenhouse gases and the running cost of the device.

Description

technical field [0001] The invention relates to a device and method for removing coal-fired inhalable particulate matter from a precursor to realize zero-emission of carbon dioxide, which is used for dust removal and purification treatment of tail gas of a coal-fired power plant boiler, and belongs to the technical field of flue gas purification. Background technique [0002] Atmospheric inhalable particulate matter has become a prominent problem of atmospheric environmental pollution, and it has increasingly attracted great attention from all countries in the world. Coal is the main fuel for power stations in China at present and for a long period of time in the future. While pulverized coal combustion provides the necessary heat and power resources, it will also bring serious pollution of inhalable particulate matter. According to statistics: in 2005, the total amount of inhalable particulate matter emitted by my country's coal-fired power plants accounted for 1.2-1.5% of ...
