Description
(1) technical field
The present invention relates to a kind of producing and use device and dilution device for phosphine gas, and in particular to hydrogen phosphide occurs
Device and nitrogen dilute auxiliary system.
(2) background technique
Currently on the market phosphine generator using when require carbon dioxide gas and dilute the phosphine gas of generation
Concentration, to achieve the purpose that safety in production.
(3) summary of the invention
Technical problem to be solved by the present invention lies in, for existing phosphine generator using when require carbon dioxide
Gas dilutes the status of the concentration of the phosphine gas of generation, provide one kind and be easy to produce, be inexpensive, and Non-combusting gas dilutes
The method of the concentration of phosphine gas.
A kind of phosphine gas of the invention produce with use and nitrogen dilution system, the phosphine gas produce
It include power supply, phosphine generator, source nitrogen (various nitrogen making machines, small nitrogen, elevated pressure nitrogen with using with nitrogen dilution system
Gas cylinder or tank), connecting line and control valve, pressure sensor, nitrogen gas purity detector, phosphine concentration detector, alarm
With protection circuit；
The phosphine generator provides aluminum phosphate medicament and reacts the phosphine gas generated with water；
The source nitrogen (various nitrogen making machines, small nitrogen, high-pressure nitrogen bottle or tank) provides purity and is higher than 98.5%
Nitrogen；
The connecting line and control valve are for connecting source nitrogen, phosphine generator and grain depot circulation fumigating system.
Preferably, the phosphine generator can be shown in fragment counting and control system, the patent No. 201210374239.6.
It has the function of that controlling the aluminum phosphate unit time feeds intake quantity.
The beneficial effects of the present invention are:
(1) nitrogen is usually nonflammable and does not support to burn, and meets the condition as diluent gas, plays safety in production
Effect.
(2) nitrogen produce it is easier than carbon dioxide, this is because nitrogen (N2) accounts for about 78% in atmosphere, carbon dioxide
(CO2) account for about 0.03%.
(3) nitrogen making machine can minimize.
(4) producing for nitrogen greatly reduces energy consumption than same volume carbon dioxide preparation, reduces pollutant emission, net to air
Change contributes.
(5) system operatio safety, and cost is cheap, is suitable for base's grain depot application.
