Preferential selection method, device and equipment of denitration efficiency prediction method

Abstract

The invention discloses a preferential selection method, device and equipment of a denitration efficiency prediction method. The method comprises the following steps: acquiring a to-be-analyzed SCR denitration system and a plurality of denitration efficiency prediction models; obtaining input parameters of each denitration efficiency prediction model when the SCR denitration system to be analyzedis subjected to denitration efficiency prediction; inputting each input parameter into a corresponding denitration efficiency prediction model to obtain predicted denitration efficiency output by eachdenitration efficiency prediction model; determining a target denitration efficiency prediction model from the plurality of denitration efficiency prediction models according to the actual denitration efficiency and all predicted denitration efficiency of the SCR denitration system to be analyzed; and taking the denitration efficiency prediction method corresponding to the target denitration efficiency prediction model as the denitration efficiency prediction method of the SCR denitration system to be analyzed. The technical problem that the denitration efficiency and accuracy of an existingSCR denitration system are not high is solved.

Description

technical field [0001] The present application relates to the technical field of denitrification analysis, and in particular to a preferred method, device and equipment for a denitrification efficiency prediction method. Background technique [0002] With the increasingly severe environmental situation, people begin to pay attention to environmental protection issues. In the power grid, the nitrogen oxides contained in the combustion flue gas of coal-fired power plants seriously affect the environment, so denitrification technology has emerged as the times require. [0003] Install SCR denitrification system in coal-fired power plants to control the emission of nitrogen oxides in flue gas. As the performance of the catalyst in the SCR denitrification system decreases, the ammonia slip rate increases, and the generated NH 4 HSO 4 Deposits cause partial blockage of the air preheater. In order to prevent local clogging, the prior art predicts the denitrification efficiency ...
