Problems solved by technology

However, chemical reagents still need to be used in this invention, and the sampling probe needs to be equipped with a filter. When the flue gas passes through the filter, the particles adsorbed on the filter will oxidize the elemental mercury in the flue gas, causing the content of elemental mercury in the measurement results to be biased. Small
In the prior art, the inertial separation filter can avoid the oxidation of elemental mercury by the adsorbed particles of the particle filter, but its filtering effect on tiny particles is not as good as that of the particle filter, and the unfiltered tiny particles may cause damage to the instruments in the subsequent loop. cause damage

Abstract

The invention discloses a continuous monitoring system for flue gas pollutants. The system is used for monitoring contents of elementary mercury, mercury ions and total mercury in flue gas. By arrangement of a sampling channel and a detection system, the influence of adsorbent particles of a particle filter in the channel on a detection result can be reduced. The continuous monitoring system for the flue gas pollutants can be applied to precisely continuous monitoring for mercury discharging of a fixed pollution source such as a chemical plant, a coal-fired power plant and a waste treatment plant, so as to realize discharge control over the pollution source and provide real-time and reliable data for environmental monitoring and environmental protection.

Description

technical field [0001] The invention relates to an automatic monitoring system, in particular to an automatic monitoring system for smoke pollutants. Background technique [0002] Mercury is an extremely harmful element to the human body, and it is volatile and accumulative. As one of the heavy metals under key control, excessive mercury emissions will not only pollute the air, but also migrate to water and soil through the exchange of various environmental interfaces, causing harm to the ecological environment and human health. Exposure to high concentrations of mercury will affect the nervous system and growth and development of the human body. Inhalation of a certain amount will deform the limbs of the human body, lose the ability to work and even die. [0003] In recent years, mercury pollution has been recognized as another major pollution problem after coal burning thiamine pollution and particle pollution. There are two main sources of atmospheric mercury pollution:...
