Abstract

The invention relates to a reducing agent jetting device, in particular to an automatic adjustment type reducing agent jetting device for denitration. The automatic adjustment type reducing agent jetting device for denitration aims to achieve the technical purposes of high denitration efficiency, large denitration area and thorough denitration. In order to achieve the technical purposes, the automatic adjustment type reducing agent jetting device for denitration comprises a first motor, a first special-shaped gear, a second special-shaped gear, a rack, a first connection rod, a first L-shaped connecting rod, a sliding rail, a sliding block, a second motor, a screw and the like, wherein a guide rod and the second motor are arranged on the upper portion of the inner right wall of a mounting support; and the guide rod is sleeved with a guide sleeve which is matched with the guide rod. The automatic adjustment type reducing agent jetting device for denitration achieves the effects of high denitration efficiency, large denitration area and thorough denitration, is low in manufacturing cost, reasonable in structure, easy to maintain and repair and convenient to use, manpower input and material resource input are reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a reducing agent injection device, in particular to an automatic adjustment reducing agent injection device for denitrification. Background technique [0002] Denitrification refers to the process of removing nitrogen oxides from combustion flue gas. The importance of preventing environmental pollution has been sharply raised as a worldwide problem. The more mainstream processes in the world are divided into SCR and SNCR. There is not much difference between these two processes except that the reaction temperature of SCR is lower than that of SNCR due to the use of catalyst in SCR. However, from the perspective of construction cost and operating cost, the investment of SCR is at least several times that of SNCR, or even More than 10 times. Denitrification is divided into denitrification before combustion, denitrification during combustion, and denitrification after combustion. [0003] Existing reductant injection devices us...
