Abstract

The invention discloses a circulating fluidized bed garbage incineration boiler and a pollution control system with the same, which relate to a garbage incineration boiler and a pollution control system with the same, and aim to solve the problems that the conventional circulating fluidized bed garbage incineration furnace difficultly discharges slag and is required to be stopped regularly to remove the slag and the economy of a garbage incineration plant is influenced. According to the scheme I, a circulating fluidized bed and double V-shaped wind distributing plates are arranged in a boiler body, the boiler body, a separator, a flue gas cooling chamber and a tail flue are communicated in sequence, an upper level low-temperature superheater, a lower level low-temperature superheater, a primary wind air preheater, a secondary wind air preheater, an upper level primary wind economizer, a lower level primary wind economizer, an upper level secondary wind economizer and a lower level secondary wind economizer are arranged in the tail flue, and the separator is communicated with the boiler body by a U-shaped valve; different from the scheme I, the scheme III is characterized in that: double inverted V-shaped wind distributing plates are adopted; different from the scheme III, the scheme V is characterized in that: an inverted V-shaped wind distributing plate is adopted; and according to the scheme II, the scheme IV and the scheme VI, a semidry reaction tower, a bag-type dust collector, an induced draft fan, a chimney, a fly ash cabin, a lime slurry preparation system, a rotary atomizer and an active carbon injecting device are added on the basis of the scheme I, the scheme III and the scheme V. The circulating fluidized bed garbage incineration boiler and the pollution control system with the same are used for incinerating garbage, and pollutant emission can be controlled.

Description

technical field [0001] The invention relates to a garbage incineration boiler and a pollutant control system thereof. Background technique [0002] According to statistics, in 2011, the total output of domestic waste in my country has exceeded 290 million tons, and it is increasing at an annual rate of 8% to 10%. A huge amount of urban garbage has become a problem that plagues my country's economic development. The incineration method has the advantages of saving land, eliminating various pathogens, large processing capacity, and fast speed. It is also equipped with a heat recovery power generation system and a waste incineration tail gas treatment system. The social and environmental benefits are huge, so the proportion of waste incineration is gradually increasing. [0003] The types of waste incineration boilers mainly include mechanical grate incinerators, rotary kiln incinerators and fluidized bed or circulating fluidized bed incinerators. Due to the lack of classific...
