Carbon fiber static bed flue-gas desulfurization and denitrification technology and device

Abstract

The invention discloses a carbon fiber static bed flue-gas desulfurization and denitrification technology. The carbon fiber static bed flue-gas desulfurization and denitrification technology sequentially comprises the following steps that (1) flue gas is pretreated, and the flue gas contains SO2 and NOx; (2) the flue gas is absorbed through a carbon fiber fixed unit, and the flue gas after absorption is directly discharged; (3) desorption is carried out; (4) NOx catalytic reduction is carried out; and (5) SO2 is absorbed. Meanwhile, the invention further discloses a carbon fiber static bed flue-gas desulfurization and denitrification device. The carbon fiber static bed flue-gas desulfurization and denitrification device is used for realizing the carbon fiber static bed flue-gas desulfurization and denitrification technology and is characterized in that the carbon fiber static bed flue-gas desulfurization and denitrification device is sequentially provided with a preprocessor, an absorption reactor, a desorption device, a reduction device and an SO2 absorption device from the upstream side to the downstream side; and the absorption reactor comprises at least two groups of switchablecarbon fiber absorption assemblies which are used alternately, and a flue gas outlet is further formed in the downstream end of the absorption reactor.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a carbon fiber fixed bed flue gas desulfurization and denitrification process and equipment. Background technique [0002] The discharge of sulfur dioxide and nitrogen oxides has caused serious acid rain pollution and ecological damage. my country is a country rich in coal resources, and it is also the largest coal producer and consumer in the world; the main form of coal utilization is direct combustion, which occupies more than 80% of the total coal, and a large amount of coal combustion produces a large amount of pollutants such as sulfur dioxide , its sulfur dioxide emissions rank first in the world, causing huge losses to the national economy and people's property, and also caused a large loss of sulfur resources in my country. Therefore, reducing and controlling pollution and preventing and controlling sulfur emissions during coal combustion are the needs of global s...

[0002] The discharge of sulfur dioxide and nitrogen oxides has caused serious acid rain pollution and ecological damage

However, due to mechanical wear and tear, a part of carbon needs to be consumed during the reduction of sulfuric acid, so regular replenishment is required.
