Abstract

The invention provides a fly ash working condition specific resistance on-line monitoring device and method.The on-line monitoring device comprises an air inlet elbow, a fly ash collecting bin, a driving mechanism, a back flushing system, a sampling gun, an induced draft fan, a high-resistance tester and a temperature and humidity tester, and a plurality of movable electrodes are arranged in the fly ash collecting bin; the driving mechanism is used for driving all electrodes in the fly ash collecting bin to switch positions, the first air inlet end, the first air outlet end, the second air inlet end and the second air outlet end of the fly ash collecting bin are connected with the air inlet elbow, the sampling gun, the back flushing system and the cleaning box respectively, and an outlet of the sampling gun is connected with the induced draft fan. The high-resistance tester and the temperature and humidity tester are both connected with the sampling gun and are respectively used for measuring the working condition specific resistance of fly ash and the temperature and humidity of flue gas, so that online monitoring of the working condition specific resistance is realized, the switching positions of the electrodes in the fly ash collecting bin are controlled through the driving mechanism, and switching use of the multiple electrodes is realized.

Description

【Technical field】 [0001] The invention relates to the technical field of flue gas monitoring devices, in particular to an online monitoring device and method for specific resistance of fly ash working conditions. 【Background technique】 [0002] The flue gas treatment system is used to treat industrial waste gas, and is widely used in the field of thermal power generation and chemical industry. In the flue gas treatment system, it is often necessary to measure the working condition specific resistance and the experimental specific resistance of the fly ash. The obtained specific resistance, the two specific resistances have reference value, so that technicians can formulate a reasonable flue gas treatment process. The current fly ash working condition ratio resistance monitoring device mostly adopts on-site sampling, and the method of laboratory measurement to obtain the working condition specific resistance can not only accurately measure the working condition specific resi...
