Flue gas analysis device

Abstract

The invention discloses a flue gas analysis device, relating to the field of boilers. The flue gas analysis device comprises an air pipe, an air pump, a first temperature sensor, a second temperaturesensor, a humidity sensor, a cooler, a first electromagnetic valve, a detection module and a control module, wherein the first temperature sensor, the cooler, the second temperature sensor and the humidity sensor are sequentially connected in series to the air pipe; the first electromagnetic valve and the detection module are connected in parallel to an air outlet end of the air pump; the air pump, the first temperature sensor, the second temperature sensor, a humidity sensor, the cooler, the first electromagnetic valve and the detection module are respectively and electrically connected withthe control module; and the controller is used for controlling the starting and stopping of the air pump, the starting, stopping and refrigerating capacity of the cooler, and the opening and closing of the first electromagnetic valve; and when the first electromagnetic valve is opened, to-be-measured gas is discharged from the first electromagnetic valve, and when the electromagnetic valve is closed, the to-be-measured gas enters the detection module. The flue gas analysis device is long in service life, and the energy consumption is saved.

Description

【Technical field】 [0001] The invention relates to the field of boilers, in particular to a flue gas analysis device. 【Background technique】 [0002] With the development of the economy, the country pays more and more attention to the protection of the environment, so the requirements for boiler emissions are also getting higher and higher, especially in Beijing, where the emission requirements for nitrogen oxides are as low as 30mg / L. In the prior art, most of the online nitrogen oxide detection and analysis devices matched with boilers are detection and analysis devices for low-temperature air analysis or short-term use products. The detection status is not conducive to saving energy consumption, and its life is short, so it cannot be used for a long time. 【Content of invention】 [0003] In order to solve the aforementioned problems, the present invention provides a novel flue gas analysis device, which is not limited by working conditions, saves energy consumption and h...
