Embodiment

[0024] Such as figure 1 As shown, an atmospheric gaseous mercury sampling device includes: a constant temperature box 1, a dryer 2, a filter 3, a flow controller 4, and an air pump 5 connected in sequence, and an adsorption gas pipe 6 partially located in the constant temperature box 1, wherein the adsorption The air suction port of the air pipe 6 is fixed outside the thermostat box 1, and the air outlet is connected to the dryer 2 through the air nozzle 7. The dryer 2, the filter 3, the flow controller 4, the air pump 5, the adsorption air pipe 6, and the air nozzle 7 Both are two and sequentially connected to form two parallel airflow channels.

[0025] The working process of the instrument of the present invention is: first the air enters the adsorption tube 6 heated by the thermostat box 1, then enters the dryer 2 and the filter 3 to remove the moisture and particles in the air, then enters the flow measurement and control part, and finally passes through the air pump Drain t...

Abstract

The invention relates to a gas sampling device, belongs to the field of environment monitoring, and in particular relates to an atmospheric gaseous mercury sampling device. The atmospheric gaseous mercury sampling device comprises a constant-temperature box, dryers, filters, flow controllers and gas pumps which are connected with one other in sequence, and adsorption gas pipes partially positioned in the constant-temperature box, wherein a gas suction opening of each adsorption gas pipe is fixed outside the constant-temperature box; a gas outlet of each adsorption gas pipe is connected with the corresponding dryer through a gas nozzle. Therefore, the atmospheric gaseous mercury sampling device has the advantages that atmospheric gaseous mercury sampling can be carried out, and the national condition requirement in China can be met; the sampling effect is good, and the constant-temperature heating box guarantees the adsorption efficiency and the penetrating rate of the adsorption pipes, and the special volume flow controllers enable the sampling flow range to be wide and the gas flow to be stable; the precision of the sampling device is high, and by virtue of a stainless steel structure, the reliability of the sampling device is also improved.

Description

Technical field [0001] The invention relates to a gas sampling device, belonging to the field of environmental monitoring, in particular to an atmospheric gaseous mercury sampling device. Background technique [0002] Due to the environmental impact of my country's gaseous mercury emissions, my country urgently needs to understand the composition of gaseous mercury pollutants, emission concentration and other factors, but in fact, my country's existing gaseous mercury sampling methods are mainly based on US EPA Method 30B, and more are for fixed The gaseous mercury sampler for pollution sources is blank for sampling equipment for gaseous mercury in the atmosphere. [0003] Since the concentration of gaseous mercury in the atmosphere will not be very high, if the sampling time is not long enough, the content of mercury adsorbed by the adsorption tube will be very low. The difficulty of detecting the concentration of gaseous mercury by analytical instruments will be greatly increased....
