The utility model discloses sampling unit can make things convenient for effectual monitoring catalyst wholeness ability. During sampling test, take out the catalyst sample from the sample box to the position of the former catalyst sample of catalyst test block loading that will be new prevents to cause and causes not the problem that the denitration flue gas passes through because of the sample.
Description
Technical field
The utility model relates to SCR denitration technical field, for thermal power generation denitrating system, and specifically a kind of sampling unit for SCR denitration module.
Background technology
Oxides of nitrogen (NO
xcomprise NO, NO
2deng compound) be one of major pollutants causing atmospheric pollution, SCR system is NO
xeffective control method, and catalyzer is as the core of SCR denitration system, and its quality and performance is directly connected to the height of denitration efficiency.SCR denitration affects by exhaust gas volumn, smoke components and the factor such as ash content, alkaline metal in operational process, and along with working time increases, catalyst module may affect by undesirable element, causes the phenomenons such as denitration efficiency decline, plug-hole.And thermal power plant is in operational process, is difficult to stop production to overhaul at any time, for solving this difficulty, sampling unit is set in module cage, be convenient to detect catalyzer denitration performance, according to testing result, overall judgement is made to SCR performance.
