Description
Technical field
This utility model relates to a kind of preparing device, a kind of be applicable to laboratory in use hydrargyrum mark liquid is converted into
The mercuric preparing device of gaseous state, belongs to technical field of measurement and test.
Background technology
Hydrargyrum is the metal uniquely existed in a liquid-like manner, and it has the characteristics such as density evaporation big, easy and severe toxicity.At present, exist
When gas mercury is analyzed experiment by laboratory, owing to not having bivalent mercury gas on market, so need to be by artificial by hydrargyrum
Mark liquid preparation is atomized into required bivalent mercury gas.This instant preparation process is the most loaded down with trivial details, the most usually adding because of hydrargyrum mark liquid
Add inaccurate, cause the consequence that the bivalent mercury concentration after atomization is below standard.In addition, with atomization after hydrargyrum mark liquid carry out proportioning
Source nitrogen, also can affect final result, usually cause because proportioning is inaccurate the accuracy of test to reduce.So people in the industry
Scholar in the urgent need to a kind of being applicable in laboratory to use, nebulization efficiency is high and has the gaseous state bivalent mercury system of relatively high mixture ratio precision
Standby device.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of experiment bivalent mercury gas prepares dress
Putting, its simple in construction, easy to operate, nebulization efficiency is high, and has proportioning precision higher.
Problem described in the utility model solves by the following technical programs:
A kind of experiment bivalent mercury gas preparation facilities, including source nitrogen, gas mass flow controller, nebulizer, hydrargyrum
Mark liquid and heating chamber；Described source nitrogen connects with the inlet end of gas mass flow controller；Described gas mass flow controls
The outlet side of device connects with heating chamber；Described hydrargyrum mark liquid is connected with one end of nebulizer by flow pump；Described nebulizer another
End is connected with heating chamber；Described heating chamber includes quartz ampoule and heater；Described quartz ampoule one end is inlet end, and the other end is for going out
Gas end；The laminating of described heater is wrapped in the outer wall of quartz ampoule.
Above-mentioned experiment bivalent mercury gas preparation facilities, described nebulizer includes atomizing piece and spongy body；Described spongy body
It is arranged on the connectivity part of nebulizer and flow pump；Described atomizing piece is arranged on the connectivity part of quartz ampoule and nebulizer.
Above-mentioned experiment bivalent mercury gas preparation facilities, described flow pump is peristaltic pump.
Above-mentioned experiment bivalent mercury gas preparation facilities, described heater is ceramic heater.
This utility model realizes quantitatively extraction by flow pump to hydrargyrum mark liquid, has effectively ensured the intake of hydrargyrum mark liquid,
Prevent hydrargyrum mark liquid and absorb the inaccurate excessive concentration caused or too low, affect the generation of the problems such as result of the test.Described hydrargyrum
After mark liquid enters nebulizer, it is atomized into tiny drop, is delivered in heating chamber so that it is be in vapor state, from gas
Mercury vapour is then blown out from heating chamber by the nitrogen of mass flow controller blowout, for experiment.It addition, described heating chamber
Using ceramic heater to heat, to avoid common heating silk directly to contact with quartz ampoule, and the quartz ampoule caused bursts
Problem.
This utility model simple in construction, easy to operate, nebulization efficiency is high, it is adaptable to uses in places such as laboratorys.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure, each list of reference numerals is: 1. source nitrogen, 2. hydrargyrum mark liquid, 3. gas mass flow controller, 4. peristaltic pump, 5. sea

Gas end connects with heating chamber, passes through polyfluortetraethylene pipe between described source nitrogen 1, gas mass flow controller 3 and quartz ampoule 8
Connection, described gas mass flow controller 3, for controlling the flow speed of source nitrogen, allows it to be atomized with variable concentrations
After hydrargyrum mark liquid carry out preferably proportioning.Described hydrargyrum mark liquid 2 is connected with one end of nebulizer 9 by flow pump；Described nebulizer 9
The other end is connected with heating chamber, and described flow pump is peristaltic pump 4, for controlling the concentration of hydrargyrum mark liquid；Described heating chamber includes stone
English pipe 8 and heater；Described quartz ampoule 8 one end is inlet end, and the other end is outlet side；The laminating of described heater is wrapped in quartz
The outer wall of pipe 8, described heater is ceramic heater 7, to avoid directly contacting of common heating silk and quartz ampoule 8 to cause
Quartz ampoule bursts problem.
It addition, the nebulizer 9 described in this utility model includes atomizing piece 6 and spongy body 5；Described spongy body is arranged on mist
Change the connectivity part of device and flow pump；Described atomizing piece 6 is arranged on the connectivity part of quartz ampoule 8 and nebulizer 9 for ultrasonic atomization.
Pipeline gas circuit is first connected before experiment starts by this utility model, and heating chamber first starts preheating, and peristaltic pump 4 sets
Good certain rotating speed, opened gas mass flow controller 3 and source nitrogen 1 after five minutes, carries out heating chamber and whole gas circuit
Emptying, starts peristaltic pump, when spongy body 5 is impregnated with hydrargyrum mark liquid 2 completely, opens nebulizer and carry out the mist of hydrargyrum mark liquid after one minute
Changing, what now outlet was flowed out is exactly the bivalent mercury steam purging tiny hydrargyrum mark liquid through nitrogen.
Gas mass flow controller 3 described in this utility model be model be the gas mass flow control of CS200-A
Device processed.
