Problems solved by technology

However, the hydrogen gas monitoring alarms currently used in industry have single functions. When the hydrogen concentration exceeds the normal range, they can only continuously send out hydrogen gas detection alarm signals, and lack more signal transmission channels, so they can only rely on manual handling. Can't proactively rule out danger
Once the risk-discharging personnel cannot be in place in time, explosions and fires are likely to occur, resulting in safety accidents

Abstract

The invention discloses a hydrogen gas automatically-monitoring and actively-protecting device. The hydrogen gas automatically-monitoring and actively-protecting device comprises a hydrogen gas detection signal processing main control circuit, a ME4-H2 hydrogen gas sensor, a relay K coil, a hydrogen gas detection PPM value LCD (liquid crystal display) display and a hydrogen gas detection acousto-optic alarm, and is characterized in that the hydrogen gas detection signal processing main control circuit is connected with each of the hydrogen gas detection PPM value LCD display, the hydrogen gas detection acousto-optic alarm, the ME4-H2 hydrogen gas sensor and the relay K coil; a circuit control switch is arranged between the ME4-H2 hydrogen gas sensor and the hydrogen gas detection signal processing main control circuit.

Description

technical field [0001] The invention relates to a protection device, in particular to a hydrogen automatic monitoring and active protection device and method. Background technique [0002] Hydrogen is widely used in petrochemical industry, electronics industry, metallurgical industry, food processing, float glass, fine organic synthesis, aerospace, etc. During the application process, the hydrogen concentration in the confined space environment may be too high, causing safety accidents. Therefore, it is often necessary to install a hydrogen concentration detection and alarm device in an industrial production operation workshop where hydrogen may be generated. However, the hydrogen gas monitoring alarms currently used in industry have single functions. When the hydrogen concentration exceeds the normal range, they can only continuously send out hydrogen gas detection and alarm signals, and lack more signal transmission channels, so they can only rely on manual handling. It ...
