Abstract

The invention discloses a portable type ozone concentration online monitoring device and an ozone concentration online method. The device comprises a housing, wherein a gas exhausting device, a filter system, a gas absorption tank and a data processing system are arranged in the housing; a data display module and a starting button for starting the device are arranged on a panel of the housing; the filter system, the gas exhausting system and the gas absorption tank are communicated through a sealed PTFE tube; the gas absorption tank and the data processing system are connected through an optical fiber. The portable type ozone concentration online monitoring device has the characteristics of being simple in structure, high in integration, convenient to operate, high in measuring precision, high in measuring speed and capable of performing online monitoring in real time, not only can be suitable for monitoring ozone concentration in a transformer station environment, but also can be used for indirectly judging an operation state of electrically charged equipment in a transformer station.

Description

technical field [0001] The invention relates to the technical field of gas monitoring, in particular to a device for on-line concentration monitoring of ozone pollution sources such as automobiles, fuels and petrochemicals. Background technique [0002] In daily life, it is often seen that the air is slightly light brown and has a pungent smell, which is commonly referred to as photochemical smog. Ozone is the main component of photochemical smog, which is formed by the photochemical reaction of nitrogen oxides and volatile organic compounds in the atmosphere. The nitrogen oxides and volatile organic compounds in the atmosphere mainly come from motor vehicle exhaust and chemical production. Ozone is a double-edged sword. It has a bactericidal effect when the concentration is low, but the concentration only needs to reach 0.43mg / m 3 The above will cause harm to human health, mainly reflected in: strong stimulation of the respiratory tract, resulting in changes in lung functi...
