Description
The utility model relates to a kind of gold and captures survey mercury auxiliary machine, and it belongs to the equipment of mercury content in the working sample.
Trace Mercury Determination on content for various samples, mostly adopt cold-vapour atomic absorption method at present, it is that the tested liquid sample that will handle well injects reaction bulb, after adding an amount of reductive agent, with clean air or nitrogen as carrier, carry out quick-fried gas by reaction bulb, the mercury element in the sample is delivered to cold atom absorption analysis instrument measure.
In order further to improve detection sensitivity, thereby now adopt and before sending into instrument for determining Hg in by carrier mercury element, utilize spun gold to capture, again spun gold is heated to uniform temperature earlier to make mercury element on it concentrate to discharge to increase unit volume mercury content in this section carrier, make and measure sensitivity and increase substantially.Use at present this gold and capture the mercury method of surveying, the equipment that still none cover can be controlled automatically, each several part is coordinated mutually: all adopt the timing of operating personnel's start the watch for the quick-fried gas of the reaction bulb time, increase labour intensity and each quick-fried gas time so not wait; Heating for spun gold is to judge that according to observation resistive heater color it is consistent that each intensification number of degrees are difficult to; With water cooling, this unfavorable cleaned in situ easily makes pipe burst again to the trap tube that spun gold is housed after heating.
The utility model purpose is: a kind of instrument for determining Hg use, energy gold capture survey mercury utility appliance of Control work program automatically that cooperates is provided.
The utility model is achieved in that by carrier gas cylinder gas cleaning unit, throttling valve, gas meter, quick-fried solid/liquid/gas reactions bottle, ice bath, de-watering apparatus, the mercury trap tube that spun gold is housed and the outer resistive heater of pipe and constitutes, its design feature is: have two quick-fried solid/liquid/gas reactions bottles, the outlet of being controlled gas meter by a coaxial pair of threeway interlocking valve communicates with some quick-fried solid/liquid/gas reactions bottle inlets and this reaction bulb outlet enters the mouth with ice bath communicates; Near the mercury trap tube, be provided with a cooling fan; A solenoid valve is equipped with in the tensimeter exit of carrier gas cylinder; Control the whole instrument working routine by the supporting control circuit that captures timing, heat timing and cooling timing circuit, fan starting circuit, resistance wire heater circuit are formed, selector switch by coaxial pair of threeway interlocking valve control is connected between power supply and capture timing circuit and the solenoid valve, capture the timing circuit output terminal and link to each other with heat timing circuit input end and resistance wire heater circuit control end, the timing circuit output terminal of heating links to each other with cooling timing circuit input end and fan starting circuit control end.
Control circuit in the such scheme can be realized like this: three timing circuits all form by resistance, electric capacity and the relay of each free double base diode, charge and discharge; Come heating of controlling resistance silk and fan cooled with the contact of relay, in the resistance wire heater circuit serial connection warm-up time relay normally closed contact, in fan starting circuit the serial connection warm-up time relay normally opened contact and one cool time relay normally closed contact.
The utility model advantage is: when adopting the timing circuit control, make that whole test process is simple to operate, test condition stable; Be provided with two quick-fried solid/liquid/gas reactions bottles and formed two-way by coaxial pair of threeway interlocking valve and replace the test sample system, improved test speed greatly.

Accompanying drawing 4 is coaxial pair of threeway interlocking valve structure vertical view in the utility model.
Accompanying drawing 5 is the pivot structure synoptic diagram of coaxial pair of threeway interlocking valve.
Below in conjunction with accompanying drawing the utility model embodiment is done an introduction.
As shown in Figure 1, present embodiment is made up of nitrogen steel cylinder 1, nitrogen pressure table 2, solenoid valve 3, gas cleaning unit 4, throttling valve 5, gas meter 6, coaxial pair of threeway interlocking valve 7 of gas circuit and 8, reaction bulb selector switch 9, I reaction bulb 10, II reaction bulb 11, ice bath 12, de-watering apparatus 13, cooling fan 14, mercury trap tube 15, resistive heater 16, spun gold 17, heating power supply 18.In this example, carrier adopts nitrogen; Mercury trap tube 15 adopting quartz glass pipes.
This example is carried out work as the utility appliance of a mercury vapor analyzer such as cooperation 590 type F732 types: the sample of handling well is injected I reaction bulb 10 and II reaction bulb 11 respectively, coaxial pair of threeway interlocking valve 7,8 and selector switch 9 are pushed corresponding I reaction bulb position, to the quick-fried gas of first sample, measure.So entire equipment just can be carried out automatic quick-fried gas by I reaction bulb 10 successively under control circuit control, make mercury vapour behind ice bath 12 and de-watering apparatus 13 further drainages, enter in the trap tube 15 and captured by the spun gold in the pipe 17, heating power supply is resistance wire 16 energisings on trap tube 15 outer walls then, mercury element adsorbed on the spun gold 17 is evaporated again, is sent in the mercury vapor analyzer by carrier nitrogen.Measure when finishing, can cut off heating power supply automatically, start cooling fan 14 is trap tube 15 and interior spun gold 17 fast coolings thereof, and fan 14 outages are then shown sample number into spectrum simultaneously, sent and measure the signal that finishes.At this moment the operator just can push the another location with interlocking valve 7 and 8, selector switch 9, second sample in another reaction bulb (II number) is carried out quick-fried gas measure.In the quick-fried gas of this reaction bulb, the waste liquid of having surveyed in the previous reaction bulb is bled off, through cleaning, inject the 3rd test sample, like this, after second test sample finishes, will change the sampling switch again and dial go back to origin-location (I bottle position) and carry out next sample measurement (the 3rd test sample), hocket down successively.
The structure of coaxial pair of threeway interlocking valve is shown in Fig. 3,4, and an one path 7 is outlets of connecting gas meter 6 with the reaction bulb inlet, and another path 8 is to be used for the inlet of outlet of coupled reaction bottle and ice bath 12.Selector switch 9 is subjected to the synchro control of rotating shaft.
