Abstract

The invention relates to an online automatic monitoring device for hydrogen of earthquake precursor. The device comprises a gas-carrying port, a sampling intake and a vent, wherein the gas-carrying port, a flow controller, a digital flow meter and a purifier are sequentially connected; after being merged with a pipeline on which the sampling intake is arranged, an output end of the purifier is connected with an input end of a separation column; an output end of the separation column is connected with a gas inlet of a hydrogen sensor; a gas outlet of the hydrogen sensor is connected with the vent; a connecting pipeline between the flow controller and the purifier is provided with the digital flow meter; and the hydrogen sensor is electrically connected with a signal amplifier which is connected with an SCM (single chip microcomputer) or an industrial computer connected with a display. The hydrogen detecting limit reaches 1 multiplied by 10<-11>L (10 ppt), which is lower than that of the existing hydrogen sensors at home and abroad by 6 order of magnitude; the sensitivity is high and the online automatic monitoring device can fully meet the requirement of earthquake detection; and the device can realize the automatic, timed and quantitative online monitoring with simple operation, is applicable to all seismograph stations, can realize the unattended operation and also can largely enhance the accuracy of earthquake forecasting.

Description

technical field [0001] The invention relates to an earthquake precursor monitoring device, in particular to an earthquake precursor hydrogen online automatic monitoring device capable of on-line, full-automatic and trace-level monitoring. Background technique [0002] Hydrogen is one of the most sensitive geochemical components in earthquake prediction, and has strong earthquake-reflecting sensitivity, especially in the short-imminent stage, which is obviously superior to other measurement items. Hydrogen is the key to provide correct earthquake prediction, the biggest problem at present is the lack of corresponding testing means. For a long time, the hydrogen test devices used for earthquake impending observation at home and abroad mainly include: [0003] 1. Palladium silver gas sensor hydrogen detection device [0004] According to the high permeability of hydrogen to palladium-silver alloy, the change value of the amount of hydrogen is obtained by means of vacuum and e...
