Description

Technical Field

[0001] The utility model relates to the technical field of smoke probes, in particular to a smoke sampling test probe. Background Art

[0002] With the development of society, the advancement of science and technology, and the development of large-scale industry, the requirements for environmental protection are getting higher and higher, and real-time monitoring and real-time processing are needed. Therefore, the continuous emission monitoring system of fixed pollution sources is particularly important, and the flue gas sampling probe of the continuous monitoring system of flue gas emissions from fixed pollution sources plays a vital role in the entire system. The flue gas in the chimney or flue is sucked by the sampling pump (equipment other than the probe) and is heated and insulated, filtered and dusted by the flue gas sampling probe to meet the requirements of high-precision primary filtration and insulation of the flue gas. It is then sent to the flue gas pretreatment unit through the electric heating pipe (an electrically heated constant temperature controlled gas transmission pipeline). After the pretreatment unit, it is finally sent to the flue gas analyzer for concentration analysis and detection of gaseous pollutants. The continuous monitoring system of flue gas emissions from fixed pollution sources needs to collect the flue gas in the chimney or flue, remove water and dust, and then send it to the gas analyzer for analysis and detection. Measurement, and generally, gas analyzers and flue gas pretreatment units are in the analysis room (monitoring room), and the flue gas sampling point should be located on the chimney or flue according to industry standards. The sampling probe is far away from the analysis room. The temperature of the flue gas in the chimney generally exceeds the ambient temperature, and some are as high as 300 degrees or more, and the flue gas contains a certain concentration of smoke. In this case, the flue gas needs to be sent to the flue gas pretreatment unit at a temperature higher than 100 degrees, otherwise, because the ambient temperature is lower than the temperature of the flue gas, the flue gas will condense water, and the mixture of water and smoke will form mud, thereby blocking the gas pipeline. At the same time, SO2 and other measured gases will dissolve in water, reducing the measured concentration. The continuous monitoring system for flue gas emissions from fixed pollution sources runs continuously 24 hours a day all year round. Therefore, the flue gas sampling probe needs to heat and insulate the flue gas and remove dust. It itself must have the functions of anti-corrosion, anti-blocking (preventing fine dust from clogging the filter element) and backblowing.

[0003] When the existing smoke sampling device is used for too long, the probe tube will be corroded by corrosive smoke particles, and it needs to be disassembled and cleaned of impurities inside in time. However, it is inconvenient to disassemble and clean the probe of the existing smoke sampling device, which causes the probe tube to be corroded and damaged, increasing maintenance costs. Therefore, the utility model proposes a smoke sampling test probe to solve the above problem. Utility Model Content
