Ash-sealing pipe ash discharging device of fly ash monitoring system

Abstract

The invention relates to a component of a fly ash monitoring system for monitoring the carbon content of boiler fly ash of an electric power plant, in particular to an ash-sealing pipe ash dischargingdevice of the fly ash monitoring system. The ash-sealing pipe ash discharging device comprises an ash-sealing pipe, wherein the upper end of the ash-sealing pipe is connected with a fly ash sampler penetrated into a flue; the middle section of the ash-sealing pipe is connected with a sensor unit; the lower section of the ash-sealing pipe is fixedly connected with a mounting plate; the mounting plate is provided with an electromagnet, the armature lower end of the electromagnet is hinged at the rear end of a lever; a supporting point of the lever is positioned in the middle; the front end of the lever is connected with a valve plug with a conical surface; the conical surface of the valve plug is sealed at an opening at the lower end of ash-sealing pipe; and a vibrator is arranged on the mounting plate. The ash-sealing pipe ash discharging device controls the ash discharging process through the valve plug, the whole ash discharging passage is smooth, and the vibration of the vibrator can assist the ash discharge in the ash discharging process, and thus the deposition of the fly ash is effectively avoided and the accuracy of detections is improved.

Description

technical field [0001] The invention relates to a fly ash monitoring system component for monitoring the carbon content of fly ash of a boiler in a power plant, in particular to an ash sealing tube ash discharge device of the fly ash monitoring system. Background technique [0002] The fly ash monitoring system is a device used to sample and detect the carbon content of the boiler fly ash in a thermal power plant. The connected sensor unit, the fly ash is sampled by the sampler and deposited in the ash sealing tube, and detected by the sensor unit, and then blown back to the flue by compressed air. In this structure, the soot sealing tube passing through the sensor unit is likely to solidify and adhere to the surface of the ash sealing tube due to the reaction with water vapor. After a period of use, the soot sealing tube is easy to be blocked, resulting in inaccurate detection results of the sensor unit. Contents of the invention [0003] The technical problem to be solv...
