水泥SNCR(尿素)脱硝喷枪及系统详细介绍:
尿素脱硝系统特点:
不使用催化剂,不产生固体废料;
安装快捷,操作简单,故障效率低,停机时能够自动清洗,能够防止尿素溶液在管路中接近;
每一个设备部件都配有备件,能够***系统安全运行。
脱硝效***,投入成本低。
因为尿素没有毒害,系统安全系数高。
对水泥厂和水泥质量没有影响;
Cement SNCR (urea) denitration spray gun and the system in detail:
Urea denitration system features:
Do not use the catalyst, do not produce solid waste;
Fast installation, simple operation, low fault efficiency, downtime can automatic cleaning, can prevent urea solution in a line close to;
Each device components are equipped with spare parts, to ensure the safe operation of the system.
The denitration efficiency and low cost.
Because there is no po***n, urea system high safety coefficient.
Has no impact on the quality of cement and cement;
雾化技术的发展趋势
喷枪是作为将涂料雾化后***的涂附在被涂物上的一种工具。以前,喷漆师傅采用的都是传统高压空气喷枪进行操作,而这种喷枪由于传递效率过低,导致大量的涂料和溶剂向大气环境中散发,严重污染大气。如今,随着汽车工业和涂装业的不断发展和人们环保意识的不断提高,各国国家和汽车公司开始逐步采用环保型的涂装材料,使涂料在喷涂过程中产生的有害挥发性物质排放量达到环保要求。所以,汽车涂料和工业涂料正向高固体化、水性化、低VOC排放化的方向发展。欧盟也曾提出了将汽车喷漆、金属装饰用油漆以及清漆中所含挥发性有机化合物(VOC)用量减少50%。
电厂脱硝工程
电厂SNCR脱硝可行性:
1. 国内外SNCR脱硝在电厂锅炉和工业锅炉上已广泛应用,脱硝率达标,该项技术已经为相关专家认定为最成熟可靠的脱硝技术;
1. The SNCR
denitrification at home and abroad has been widely used in power plant boiler
and industrial boiler, denitration rate up to standard, the technology has
relevant experts identified as the most mature and reliable denitration
technology;
2. 锅炉烟气的温度有符合SNCR反应的***温度范围,可以确保高的脱硝率。
2. The boiler flue gas
temperature in SNCR reaction of the best temperature range, can ensure that the
highest denitration rate.
3. 中小型锅炉炉膛和烟道截面积小,有利雾场分布和还原剂的混合,确保脱硝率。
3.
The middle and small boiler furnace and flue cross-sectional area is small,
good fog field distribution and the mixture of reductant, ensure the
denitration rate.
4. 投资低且不需要对锅炉进行改造,对锅炉系统的正常运行基本无影响;
4. Low investment and no
need to modification of the boiler, basic no effect on the normal operation of
the boiler system;
电厂锅炉SNCR脱硝系统有氨水和尿素两种还原剂,以下分别对两种系统进行介绍。
