   产 品 说 明
What:
what is “uniform sampling system”?
均匀取样系统是一款应用于脱硝出口、氮氧化物和氨气测量的产品,主要通过改变测量环境,提升仪表测量准确度。
"Uniform sampling system" is a product used in the measure on denitrification, nitrogen oxides and ammonia. It mainly improves the measure accuracy of the instruments by changing the measure environment.
Why均匀取样系统为何是电厂必需设备?
Why:
why dose the “uniform sampling system” necessary for a power plant?
NOXNH3测量在电厂环保运营中十分重要,NOXNH3的测量结果直接影响脱硝自动运行及喷氨调节,因测量不精准可能导致过量喷氨,从而导致氨水浪费,并形成氨盐堵塞空预器等影响设备运行的情况;喷氨不足则会导致脱硝效率不达标,NOX排放超标。但以往NOXNH3测量效果一直不如人意,特别是氨逃逸仪表基本形同虚设。
NOX and NH3 measure is very important for the power plant to do the environmental protection, the results of NOX and NH3 affect the denitrification and ammonia spraying automatic operation regulation for the measurement is not accurate, may lead to excessive ammonia, resulting in waste ammonia, and the formation of ammonium salt blockage in air preheater of equipment operation condition; ammonia injection is inadequate will cause the denitration efficiency standards, NOX emissions exceed the standard. But in the past, NOX and NH3 measurement effect has been unsatisfactory, especially ammonia escape instrument basically non-existent.
均匀取样系统通过将烟道内各个部位抽取样气进行混合后进行除尘处理,使改造后的脱硝出口NOX测量值与烟囱出口NOX值基本一致,NH3测量数据需较之前曲线有明显的改善。
"Uniform sampling system by flue gas are mixed in various parts of sampling after the dust removal processing, so that after the transformation of the denitration export NOX measurements and the chimney outlet NOX is consistent, NH3 measurement data curve is obviously improved than before.
Function均匀取样系统具有以下功能:
Function:
the uniform sampling system has the following functions:
1、自我检测:取样管具有烟气流量监测与堵塞报警功能。
1 self inspection: the sampling tube has the function of smoke flow monitoring and blocking alarm.
2、使用便捷:维护量小,并且可以在线维护而不影响使用。
2, easy to use: maintenance is small, and can be maintained online without affecting the use.
3、适用性广:适用于多种仪表,包括抽取式及原位式仪表。
3, wide applicability: applicable to a variety of instruments, including extraction and in situ instrument.
4、适应性强:能适用锅炉多种负荷,多种工况运行。
4 strong adaptability: it can be applied to various loads of boiler and operate in many working conditions.
5、耐用性强:主要部件使用寿命在10年以上。
5, durability: the main components of the service life of more than 10 years.
6、细节考究:充分考虑到了防磨、防拉、防堵等细节。
6, the details of the exquisite: full consideration to the anti grinding, anti pull, anti blocking and other details.
Effect均匀取样系统带来的经济效益与社会效益
Effect: 
economic benefits and social benefits brought about by "uniform sampling system"
1、减少浪费:测量准确有利于合理控制喷氨,避免过量喷氨造成浪费。
1, reduce waste: accurate measurement is conducive to reasonable control of ammonia spraying, avoid excessive ammonia, resulting in waste.
2、减少排污:合理控制喷氨有利于防止NOx排放超标,降低排污费用。
2, reduce pollution: reasonable control of ammonia is conducive to prevent excessive discharge of NOx, reduce sewage charges.
3、减少投入:真实准确数据有利于优化控制,减少运维人员劳动投入。
3, reduce investment: true and accurate data is conducive to optimizing control and reduce labor input of operators.
4、减少故障:测量准确有利于减少铵盐、硫酸氢铵形成,减少空预器堵塞概率。
4, reduce the failure: accurate measurement is conducive to reducing ammonium salt, ammonium sulfate formation, and reduce the probability of air preheater blocking.
5、避免事故:准确测量合理控制喷氨可以防止催化剂中毒。
5, avoid accidents: accurate measurement, reasonable control of ammonia can prevent poisoning of catalyst.
