Problems solved by technology

[0003] However, the above-mentioned gas analysis system only adds a heating device to the sampling probe and the electric heating sampling line, and the temperature is relatively low (about 120°C)
When the sample gas enters the filter and refrigerator, because the sample gas loses heat tracing, the tem

Example Embodiment

[0020] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the following further describes the embodiments of the present invention in detail with reference to the accompanying drawings and specific implementations.

[0021] This embodiment provides an online analysis system for waste incineration flue gas, such as figure 1 As shown, the online waste incineration flue gas analysis system includes a sampling probe 1, an external heat tracing sampling line 2, a sampling pump 3, an internal heat tracing sampling line 4, and a gas analyzer 5 in sequence along the transmission direction of the sample gas.

[0022] The sampling probe 1 contains a sample gas filter 11 capable of removing dust in the sample gas. The sample gas filter 11 can block particles with a particle size greater than or equal to 2 μm, and prevent large particles from entering the external heating sampling pipeline 2. The sampling pump 3 is accompanied b

Abstract

The invention discloses an on-line analysis system for waste incineration flue gas. The on-line analysis system for waste incineration flue gas sequentially includes: a sampling probe, an external heating sampling pipeline, a sampling pump, and an internal heating sampling pipeline along the transmission direction of the sample gas. and a gas analyzer; the sampling probe contains a sample gas filter that can remove dust in the sample gas; the sampling pump is accompanied by a heater to maintain the temperature of the sample gas; the gas analyzer is suitable for analysis and detection up to 200°C high temperature sample gas. After the sample gas is collected by the sampling probe, it is transmitted to the gas analyzer through the external heating sampling pipeline, sampling pump, and internal heating sampling pipeline. When the sample gas enters the gas analyzer, the composition of the sample gas collected by the sampling probe is consistent, improving High-temperature sample gas that ensures the measurement accuracy of each component content in the sample gas.
