Problems solved by technology

In the prior art, the commonly used high-temperature flue gas analyzer is mainly suitable for the temperature range of 300~1100°C, and the content of particulate matter in the flue gas is high, which is easy to cause blockage at the jet nozzle of the gas jet device, the equipment life is short, and it is very easy to damage
There is frictional resistance on the inner wall of the pipeline, and there is a problem of uneven distribution of components and concentrations during the flow of gas in the pipeline, which leads to the accuracy of the test results to be improved

Abstract

The invention is suitable for gas online monitoring, and particularly relates to a high-temperature garbage pyrolysis gas online monitoring system and method. The system comprises a multi-point gas collecting device, a filtering device, a buffering device, a two-way peristaltic pump and a gas sensor which are sequentially communicated through a communicating pipeline. The multi-point gas collecting device can extend into a plurality of positions in the garbage pyrolysis gas pipeline to carry out multi-point continuous automatic detection. During use, the first switch valve and the second switch valve (other valves are in a closed state) are opened, and the bidirectional peristaltic pump is opened in the forward direction so that the detection passage is communicated. The multi-point gas collecting device extends into the garbage pyrolysis gas pipeline to carry out gas collection and analysis at multiple positions, compared with a traditional single-point collection mode, the scheme can realize multi-point continuous automatic detection of different areas in the pipeline, and the obtained result is closer to the actual working condition.

Description

technical field [0001] The invention relates to gas on-line monitoring, in particular to an on-line monitoring system and method for high-temperature garbage pyrolysis gas. Background technique [0002] With the acceleration of my country's urbanization process, the output of urban domestic waste has increased sharply, and the phenomenon of "garbage siege" is becoming more and more serious. Melting pyrolysis technology is an anaerobic heat treatment of domestic waste, which prevents the formation of dioxins from the source, and the combustible gas produced by pyrolysis can be used for power generation and combustion for heat supply, etc. chemical, harmless" treatment. [0003] The high-temperature pyrolysis of combustibles in domestic waste is a crucial part of the melting and cracking line treatment process. The composition and concentration of pyrolysis gas is an important basis for the control optimization of waste melting and pyrolysis process, and the control of combus...
