Dilution Gas Sampling Probe series

详情

Dilution Gas Sampling Probe series     Dilution CEMS uses atmospheric grade PPb analyzer. Moisture and escaping NH3 may cause interface even damage to the NOX analyzer & CH4 kicker tube of SO2 analyzer. This probe uses unique external large proportion dilution sampling technology. It overcomes the loss caused by condensate water to the measured components in the process of sample gas pretreatment. Unique NH3 removal technology can avoid high concentration of escaping NH3 diluted into the analyzer, thus will protect analyzer from the crystallization.
 
Features
☆More stable dilution ratio,better consistency☆Reduce the water content in the sample gas, co-   mpletely eliminate the measurement influence of   condensed water☆After remove dust & NH3, sample gas complete-   ly meets the requirements of the analyzer☆No need heating line☆Sample gas transmission fast, less maintenance & consumables☆Double filtration( sampling probe cavity and sonic hole ), filtration level    0.1µm, effectively prevent sonic hole clogging☆Backblow function, suitable for high dust, high pollution conditions☆Escape NH3 removal rate is above *9%☆Standard dilution ratio: 1:**0 (other ratios are optional)
 
Principle
Step 1. The original flue gas enters the high temperature chamber after            passing the rod, the primary dust filtration begins in the chamber. Step 2. Filtered flue gas enters the NH3 remover,  the escaping NH3 is fil-            tered out to ensure that the sonic hole will not be blocked. Step 3  The flue gas enters the sonic hole. After being mixed with zero gas,            it enters the sampling pipeline under the power of jet pump. 
        Under this probe, there is no cold points, no SO2 loss in whole process.EscapingNH3 is completely removed. Thus it can ensure accurate and stable operation in theanalysis system.
