Embodiment Construction

[0020] see Figure 1-2 , A boiler flue gas detection device, comprising a flue gas sampling mechanism, a dehumidification cooling mechanism, a flue gas separation mechanism, a flue gas storage mechanism, a flue gas detection mechanism, a connecting pipeline, and a control mechanism.

[0021] The flue gas sampling mechanism is used to extract flue gas, and includes a sampling box 10 that can be arranged in the flue 13. The bottom of the sampling box 10 is provided with a sampling port 11, and the sampling box 10 is provided with a number of inclined Arranged baffles 12. The dehumidification and cooling mechanism is used to remove moisture in the flue gas, and can be used to reduce the temperature of the flue gas to meet the detection requirements of the detector 50 . It includes a condensing box 20, a plurality of condensing plates 21 arranged in the condensing box 20, and gaps for flue gas flow are provided between the condensing plates 21. The gap between the condensing pla...

Abstract

The invention discloses boiler flue gas detection equipment, which comprises a flue gas sampling mechanism, a dehumidifying and cooling mechanism, a flue gas separation mechanism, a flue gas storage mechanism, a flue gas detection mechanism, a connecting pipeline and a control mechanism; a sucking pump of the flue gas separation mechanism is controlled by the control mechanism to work, and flue gas is sucked from a flue through a sampling box of the sampling mechanism; smoke continuously enters an air exhaust cavity from the sampling opening of the sampling box, and meanwhile, due to continuous working of the air exhaust pump and continuous entering of the smoke, air in the air exhaust cavity can be effectively extracted and exhausted, so that interference of the air in the air exhaust cavity on smoke detection is facilitated. According to the equipment disclosed by the invention, the whole process of sample smoke collection, cooling, storage and detection is isolated from the outside and is controlled by a control system, so that automatic collection, cooling and detection are realized, the manual demand is greatly reduced, different gas can be independently and quickly detected at one time, and the detection of the different gas is independent and is not interfered.

Description

technical field [0001] The invention relates to a boiler flue gas detection device. Background technique [0002] The detection of boiler flue gas is mainly by detecting the concentration of O2, CO, NO, CO2 and other gases in the flue gas at the tail of the boiler and the temperature of the flue gas to calculate various heat losses of the boiler, boiler thermal efficiency and fuel combustion indicators, and evaluate The operating performance of the boiler and whether the emission meets the standards, and provide a basis for optimizing the combustion status of the boiler. [0003] At present, boiler flue gas detection is carried out through manual extraction of flue gas samples and detection by corresponding instruments, or by placing flue gas component analyzers and flue gas temperature measuring instruments on the boiler flue. Due to the harsh environment of the flue, it is difficult to manually extract the flue gas, and due to the influence of the flue gas, it will affect...
