Abstract

The invention discloses a denitration agent, a preparation method and a dry-process denitration method, and relates to the technical field of flue gas treatment. The denitration agent comprises 1%-20%of super absorbent resin, 10%-70% of urea, 1%-30% of silicon dioxide, 1%-30% of kaolin, 1%-20% of melamine, 0.1%-10% of potassium permanganate, 1%-20% of cyanuric acid, 1%-20% of talcum powder and 1%-10% of baking soda. The preparation method comprises the step of mixing the raw materials to obtain the denitration agent. The denitration method comprises the following steps: spraying the denitration agent into a temperature region of 700-1150 DEG C in a hearth, so as to remove nitrogen oxides in the flue gas through reaction. The denitration efficiency of the denitration agent on flue gas is at least 80% or more, an SCR process can be completly replaced, the denitration cost is reduced, the operation difficulty is reduced, the denitration efficiency is improved, and the nitric oxide emission standard is met.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a denitration agent, a preparation method and a dry denitration method. Background technique [0002] In the current flue gas treatment and denitrification system, selective non-catalytic reduction (SNCR) refers to the reduction of nitrogen oxides in the flue gas to harmless of nitrogen and water. This technology generally uses ammonia, urea or hydrogen acid in the furnace as a reducing agent to reduce NOx. The reducing agent only reacts with NOx in the flue gas, and generally does not react with oxygen. This technology does not use a catalyst, so this method is called Selective Non-Catalytic Reduction (SNCR). Since the process does not use a catalyst, a reducing agent must be added in the high temperature zone. The SNCR process is relatively simple, but the denitrification efficiency is low, which cannot meet the increasingly stringent environmental protection requ...
