Fault-tolerant automatic water replenishing device and working method

Abstract

The invention discloses a fault-tolerant automatic water supplementing device and a working method. The fault-tolerant automatic water replenishing device comprises a water pump, an external water bucket, a hydrogen generator water storage tank and a hydrogen generator electrolytic tank, one end of the water pump is communicated with the external water bucket, and the other end is communicated with the hydrogen generator water storage tank; and the bottom of the hydrogen generator water storage tank is connected to the hydrogen generator electrolytic tank to supply water to the hydrogen generator electrolytic tank. The device has the beneficial effects that the air pressure liquid level sensor is only in contact with air and is not in contact with liquid, so that the risks of corrosion, microorganism generation and the like are reduced; the three liquid level sensors adopt photoelectric sensors, the liquid level is judged according to different refractive indexes of transparent liquidand air, and compared with a floating ball sensor, the reliability is higher.

Description

technical field [0001] The invention relates to the field of FID detectors, in particular to a fault-tolerant automatic water supply device and a working method. Background technique [0002] The environmental protection supervision department needs to carry out online continuous monitoring of volatile organic pollutants in the exhaust gas of more and more production enterprises and the ambient air in the surrounding environment. The current online continuous monitoring method that meets the national standard is the gas phase monitoring method using FID (flame ionization detector). Chromatographic instruments. As the combustion gas source for the flame generated by the FID detector - hydrogen is an essential part of the monitoring system. [0003] The online monitoring equipment is generally unattended for a long time, and most of the hydrogen sources are hydrogen generators that use electrolyzed water. However, the online hydrogen generator is limited by the volume of the...

Problems solved by technology

[0005] Since the liquid level sensor is mostly a floating ball mechanical sensor, it is easy to have problems such as insensitivity of liquid level detection and mechanical structure jamming, which will cause the liquid level detection to fail.

When the detection of water shortage level fails, it will cause the electrolytic cell of the hydrogen generator to dry out due to water shortage, and then damage the hydrogen generator; The water storage tank overflows and flows into the hydrogen generator and other electrical equipment, causing serious accidents such as equipment corrosion and electric leakage; at the same time, the water pump is continuously powered on for too long and cannot pump water, and the water pump will also be burned.

The above serious problems are all caused by the failure of the liquid level detection sensor
