Description

Technical Field

[0001] The utility model relates to the technical field of condensed water recovery devices, in particular to a CO online monitoring condensed water recovery device. Background Art

[0002] Patent CN107013907A proposes a system for utilizing waste heat from the tail gas of a pulverized coal boiler for pulverized coal preparation. The pulverized coal preparation system relies on the flue gas from the boiler as a heat carrier, and the heat provided by the hot blast furnace is used for auxiliary heating to provide air volume and heat for the entire pulverizing system. In order to ensure the safe operation of the pulverizing system during the production process, CO online monitoring is added at the outlet of the hot blast furnace (at the inlet of the flue gas from the boiler). The purpose is to more accurately monitor the CO content of the boiler flue gas. When the CO content in the dust collector of the pulverizing system rises, it is compared with the CO value of the boiler flue gas to determine whether the system operation is safe and to prevent the occurrence of spontaneous combustion of pulverized coal.

[0003] However, during the production process, the boiler flue gas contained a large amount of water vapor and soot, resulting in inaccurate CO monitoring at the boiler flue gas inlet. This seriously interfered with production safety. When the CO value in the dust collector rose, it was impossible to distinguish whether the system was safe. Furthermore, personnel were required to immediately dismantle and clean the sampling tube of the boiler flue gas CO monitoring device. Each cleaning could only operate for about three hours before malfunctioning again. After dismantling, it was found that the main cause was a large amount of water and soot in the CO sampling tube. The multiple daily cleaning operations were not only detrimental to production safety monitoring but also labor-intensive.

[0004] The main reason for the blockage of the sampling tube is that when the CO sampling pump is working, it draws the hot flue gas in the flue gas pipe into the sampling analyzer for gas analysis. After the hot flue gas (flue gas from the boiler is about 120 degrees) is drawn out of the flue gas pipe, the temperature drops sharply, causing the hot flue gas to condense and produce condensed water droplets. The condensed water droplets are accompanied by a certain amount of soot, which finally clogs the sampling tube, resulting in poor practicality. Utility Model Content
