Description
Technical field
A kind of ground vapor interface mercury flux on-line measurement system is the utility model is related to, belongs to mercury flux measurement technical field.
Background technology
Mercury is a kind of volatile heavy metal, and huge pollution can be caused to ecological environment and brings ecological risk.Greatly
Mercury in compression ring border is in addition to the discharge from artificial source, and earth's surface can also discharge mercury to air, while air also can be by dry
Mercury is input to earth's surface by wet deposition.Therefore, the mercury between earth's surface and air is there is two-way exchange, by measuring ground vapor interface mercury
Flux may determine that the settling amount of regional atmospheric mercury and the mercury emission of earth's surface, and then for the mercury of assessment area environment
Pollution provides data and supports.In addition, ground bicycle pump flux is carried out to the region in some mercury pollution places and mercury contaminated soil reparation
On-line monitoring, can effectively assess potential mercury pollution risk and mercury pollution repairs effect.
At present, it is domestic also without the equipment and measuring system of measurement ground vapor interface mercury flux, it is main to be led to using external mercury
Measure the mercury toxicity of on-line monitoring system measurement ground vapor interface.The automatically bicycle pump that Fig. 1 show certain foreign well-known manufacturer exists
Line measuring system, it is mainly made of 1, atmospheric mercury analyzer 2 of a computer, special 4 and one controller 3 of valve module,
The technical solution controls the solenoid valve inside special valve module 4 programmatically to open and close to allow Mercury In The Air by controller 3
Analyzer 2 measures the Mercury In The Air concentration of 7 gas outlet of flux box and air inlet.Meanwhile for the air-flow inside equilibrium flux case, need
Two aspiration pumps 6 and flowmeter 5 to be installed before 2 sample introduction of the gas outlet position of flux box 7 and atmospheric mercury analyzer, respectively with 14
Liter/min and 1 liter/min be evacuated and discharge.
The link of automatically bicycle pump on-line measurement system pipeline shown in Fig. 1 is complex, and component is relatively more, the mistake of installation
Easy wrong pipeline and component in journey.At the same time, it is necessary to configure special controller 3 to atmospheric mercury analyzer 2 and special valve module 4
On-line measurement could be realized by carrying out Collaborative Control, and certain burden is brought to maintained equipment.Need to preselect when installation to set
Program carrys out the working status of control valve group, once set mistake or controller to break down, it will cause atmospheric mercury analyzer 2
The data of measurement are not used to calculate mercury toxicity.In addition, the system only with an atmospheric mercury analyzer 2, it is necessary to control
Device 3 controls 7 gas outlet of measurement flux box alternately of atmospheric mercury analyzer 2 and air inlet Mercury In The Air concentration, this is allowed for cannot
The Mercury In The Air concentration of measurement 7 gas outlet of flux box online at the same time and air inlet is realized in real meaning Shangdi, so as to cause to calculate
Mercury flux out is there are certain error, and the mercury flux calculated if the time interval of alternately measurement is longer
Error can be bigger.Equally, if controller 3 breaks down, also resulting in the data of measurement can not use.
Currently, it is logical with being discharged to mercury pollution place and mercury contaminated soil reparation achievement evaluation and some other earth's surface mercury
Measurement demand increases, and above-mentioned ground vapor interface mercury flux measurement system is because its connection is complicated, component is more, needs outer special controller
With valve module etc., it has not been convenient to carry and the field inspection station uses, and can not achieve flux box air inlet and gas outlet air
Measured while mercury flux, there are certain error.Therefore, the ground vapor interface mercury of a kind of simplification and accuracy of measurement higher exchanges
The demand of system looms large.Research and development are a kind of simplified portable and can meet practical application, and the ground vapor interface that maintenance cost is lower
Mercury exchange system is necessary.
