Hydrogen sensor has been quickly and widely used due to its powerf. It roughly includes the following aspects:
industrial use
Hydrogen is the main industrial raw material. As well as the most important industrial gas and special gas. It has a wide range of applications in petrochemical, electronic industry, metallurgical industry, food processing, float glass, fine organic synthesis, aerospace, etc. At the same time, hydrogen is also an ideal secondary energy (secondary energy refers to the energy that must be produced from a primary energy such as solar energy, coal, etc.). In addition, hydrogen can also be used as a raw material for synthetic ammonia, synthetic methanol. Synthetic hydrochloric acid, a reducing agent for metallurgy, and a hydrodesulfurization agent in petroleum refining, etc.
medical use
In 2007, Ohsawa’s report on the selective antioxidant effect of hydrogen and the treatment of cerebral ischemia in rats pioneered the use of hydrogen in the medical field. The molecular effects of hydrogen can exist in a variety of tissues and diseases. Such as the brain, spinal cord, eyes, ears, lungs, heart, liver, kidney, pancreas, small intestine, blood vessels, muscles, cartilage, metabolic system, perinatal diseases and inflammation, etc. . The number of hydrogen biology articles per year, such as 3 in 2007, 15 in 2008, 26 in 2009, 50 in 2010, 63 in 2011, and 95 in 2012, has shown explosive growth. In addition, hydrogen gas has obvious protective effects on the dysfunction of central nervous system diseases represented by cerebrovascular diseases and senile dementia, and has a therapeutic effect on cerebrovascular diseases and neurodegenerative diseases. The treatment effect of the disease is obvious.
fuel application
Hydrogen can be used as fuel and has the characteristics of rich resources, high heating value, and cleanliness.
However, although hydrogen has a wide range of uses, it also has many shortcomings in its use. It is not easy for hydrogen to be safely stored and transported. It is light in weight, elusive, and spreads fast. It needs to be liquefied at low temperature, which can cause valve blockage and build up unnecessary pressure.
The hydrogen gas detector responds quickly and accurately to hydrogen detection to ensure that it can alarm in time when a hazard occurs. It is the most sensitive and alarm-detecting gas detector in the industrial field today. Its design can adapt to these extremely harsh working environments. Mainly include the following three commonly used hydrogen gas detectors:
Portable hydrogen detector. The portable hydrogen leak detector can continuously detect the hydrogen concentration in the working environment. The hydrogen leak detector is a natural diffusion method to detect gas concentration. It uses imported electrochemical sensors with excellent sensitivity and excellent repeatability; the hydrogen detector uses embedded micro-control technology, with simple menu operation, complete functions, high reliability, and integrity. The performance of the machine is at the leading domestic level.
Pump suction hydrogen detector. The pump suction hydrogen detector uses a built-in suction pump, which can quickly detect the hydrogen concentration in the working environment. The pump suction hydrogen detector adopts imported electrochemical sensor, has a very clear large LCD display, sound and light alarm prompts, to ensure that dangerous gases can be detected in a very unfavorable working environment and prompt the operator to prevent it in time.
Monitoring principle
The hydrogen detector converts the hydrogen concentration detected by the sensor into an electrical signal, which is transmitted to the gas detection alarm controller through a cable. The higher the gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm controller , The gas detection alarm controller sends out an alarm signal, and can activate external equipment such as solenoid valves and exhaust fans to automatically eliminate hidden dangers. The fixed hydrogen detector IoT is widely used in petroleum, chemical industry, metallurgy, electric power, coal mine, water plant and other environments to effectively prevent explosion accidents.
