The Fijian zhuo cement SNCR (ammonia) denitration project details:
To the Fiji SNCR (ammonia) denitration system mainly includes: ammonia unloading system, storage system, water system, mixing system, pressure system, measuring system, distribution system, atomization system, rinse system and spray system, sewage system, control system.
The characteristics of the system are as follows:
Do not use the catalyst, do not produce solid waste;
A high degree of automation, don't need reductive dissolution process;
The fault the repair rate is low, operation simple and convenient;
High denitration efficiency, low investment.
No difference to the quality of cement production process and cement;
3HVLP环保省漆喷枪和RP省漆*喷枪有一个共同的特点,即雾化气压较低,涂料的传递效率都高于65%以上,在喷嘴结构上也还有一个共同的特点,就是都采用了当今*的一项设计即空气扰流板设计(图五),这样就确保了雾化空气均匀地从风帽内部喷射出,当雾化空气均衡后,其雾化的涂料也就非常均匀,从而也就保证了涂料颜色的喷涂均匀。
由于RP省漆*喷枪的涂料传递效率已非常接近HVLP喷枪,以往在美国只能使用HVLP喷枪,但从去年起,RP省漆*喷枪已获得美国20多个地区的认可及批准使用。
