Flue gas mercury sampler

Abstract

The invention discloses a flue gas mercury sampler, which comprises a sampling gun, a sampling tube is arranged inside the sampling gun, a sampling head capable of absorbing mercury is fixed at the inlet end of the sampling gun, a processing box is installed at the gas outlet end of the sampling gun, and the processing box A refrigeration block is installed inside. There is an air passage connected to the outlet end of the sampling tube inside the refrigeration block. A filter is installed on the outlet section of the sampling tube. There is also a condensation pipe extending up and down inside the refrigeration block. The lower end of the condensation pipe is connected to the upper end of the air outlet pipe. A flow meter is installed on the outlet section of the condensation pipe, and an air suction pump is installed on the air outlet end of the condensation pipe. The processing box is also equipped with a controller and a human body electrically connected to the above-mentioned semiconductor refrigeration chip, fan, flow meter, air suction pump and drainage mechanism. computer interaction system. The advantage is that it can realize the separation of mercury and gas, can effectively filter out the water vapor in the flue gas, has fast water removal speed, accurate detection, convenient portability and simple operation.

Description

technical field [0001] The invention relates to a flue gas mercury sampler. Background technique [0002] As we all know, heavy metal mercury is toxic in any form, and its unique persistence and corresponding bioaccumulation effects will bring harm to environmental organisms. In recent years, with the improvement of people's health awareness, the pollution and prevention of heavy metal mercury in the environment have also received extensive attention. Mercury particles mainly come from coal combustion in power plants, industrial boilers, waste combustion and some industrial processes, so it is particularly important to monitor and prevent heavy metal mercury in the flue before it is discharged into the atmosphere. [0003] However, since there is no flue gas mercury emission standard in China, the sampling and analysis of flue gas mercury has not been systematically carried out in my country, and related products of mercury samplers cannot be found, resulting in the current...
