Side inlet type multi-bin SCR reactor flue gas flow equalizing device

Abstract

The invention provides a side inlet type multi-bin SCR reactor flue gas flow equalizing device which comprises a plurality of SCR reactor bodies arranged side by side, an inlet flue communicated with gas inlets of the SCR reactor bodies and an outlet flue communicated with gas outlets of the SCR reactor bodies. The inlet flue comprises a smoke inlet pipeline, an elbow, an inlet horizontal pipeline, an inlet conical section pipeline and a first flow guide part, the smoke inlet pipeline, the elbow, the inlet horizontal pipeline and the inlet conical section pipeline are sequentially communicated, the elbow is communicated with one end of the inlet horizontal pipeline, and the inlet horizontal pipeline is located over the SCR reactor bodies which are arranged side by side; the bottom of the inlet horizontal pipeline is communicated with the SCR reactor bodies in a one-to-one correspondence mode through the multiple inlet conical section pipelines, and the first flow guide part is arranged in the inlet horizontal pipeline and used for changing the smoke direction and enabling smoke to enter the inlet conical section pipelines. According to the invention, flue gas can vertically and uniformly enter the SCR reactor bodies.

Description

technical field [0001] The invention relates to the technical field of flue gas denitrification, in particular to a side-entry multi-chamber SCR reactor flue gas equalization device. Background technique [0002] Nitrogen oxides (NO X ) is one of the main pollutants in the environment, which will cause chemical smog and acid rain and other hazards, and have a huge destructive effect on the ecological environment and human health. Since most of my country's industrial furnaces use coal or natural gas as fuel, they become major emitters of nitrogen oxides. At present, the requirements for environmental protection indicators in the domestic industrial field are getting higher and higher. In order to achieve NO X Low emission, the existing flue gas denitration methods include air staged combustion, low nitrogen combustion, selective catalytic reduction (SCR), selective non-catalytic reduction technology (SNCR), SNCR / SCR combination technology, etc. Among them, SCR denitrificat...
