Discharge pressure and concentration detection device of boiler incineration flue gas after purification treatment

Abstract

The invention discloses a device for detecting discharge pressure and concentration of boiler incineration flue gas after purification treatment, and relates to the technical field of flue gas emission detection. Both ends are fixed by a fixing mechanism, a rotating seat is arranged on the outside of the smoke concentration sensor, a number of smoke pressure sensors are arranged on the rotating seat, and a rotating fixing ring is installed at both ends of the fixing rod through bearings. The rotating fixed ring and the rotating seat are connected by a connecting rod, and the concentration and pressure of the boiler flue gas discharged after purification can be detected by the flue gas concentration sensor and the flue gas pressure sensor, so as to avoid the excessive influence of the toxic and harmful gases discharged. Atmospheric environment, the design of the rotating seat can protect the flue gas concentration sensor and flue gas pressure sensor, and avoid long-term exposure to high temperature environment to affect the service life.

Description

technical field [0001] The invention relates to the technical field of flue gas emission detection, in particular to a discharge pressure and concentration detection device after boiler incineration flue gas purification treatment. Background technique [0002] When the boiler is incinerated, a large amount of flue gas will be generated. The flue gas contains a large amount of sulfur dioxide, nitrogen oxides, dust and other harmful substances. Direct emission will harm the atmospheric environment. Therefore, the flue gas generated by the boiler incineration will be purified before discharge. Purification of equipment to reduce the discharge of toxic and harmful substances; [0003] However, when the flue gas treated by the purification equipment is discharged, it cannot be guaranteed that 100% of the flue gas meets the national emission standards. Therefore, the real-time detection of the purified flue gas is particularly important. In the prior art, for boiler smoke For ga...

[0003] However, when the flue gas treated by the purification equipment is discharged, it cannot be guaranteed to meet the emission standards stipulated by the state. Therefore, the real-time detection of the purified flue gas is particularly important. In the prior art, for boiler smoke Most of the detection of gas directly installs the sensor inside the flue, and when the flue gas is discharged, the temperature is high, and the detection in a high temperature environment for a long time will reduce the service life of the detection sensor, and at the same time, make the detection result inaccurate. Moreover, it is also difficult to clean the detection sensor;
