Problems solved by technology

[0004] The above-mentioned monitoring systems all have the following major deficiencies: 1) the cost is high, and the diaphragm pump, dewatering device and condensing device all require corrosion resistance, and the price of the corrosion-resistant pump and condensing device is relatively high; 2) the service life is short, so the Both the diaphragm pump and the condensing device are moving parts, and they all work continuously, which reduces the trouble-free service time of the system; 3) the diaphragm pump and the condensing device both need power supply, and the power consumption is large; 4) the system structure is complex , there are many leaking and faulty devices, and the reliability is low

Description

technical field [0001] The invention relates to a continuous monitoring system for flue gas emission, in particular to a continuous monitoring system (CEMS) for flue gas emission which does not need a water removal and condensation device, and uses a jet device to extract and analyze gas in a pipeline to be tested. Background technique [0002] A continuous monitoring system for flue gas emission, comprising a sampling device, a heat tracing pipeline, a water removal device, a condensing device, a diaphragm pump and a measuring device. The flue gas in the pipe to be tested is sampled by the sampling device, and then sent to the dehydration device through the heating pipeline to remove water, and then further dewatered by the condensing device, and then sent to the measuring device to measure various gases in the flue gas after passing through the condensing device Components such as sulfur dioxide, nitrogen monoxide, oxygen and other concentrations. Measuring devices usuall...
