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 dilution accessory system.
(2) background technology
Carbon dioxide is required for when phosphine generator is used in the market to dilute the phosphine gas of generation
Concentration, to reach the purpose of safety in production.
(3) content of the invention
The technical problems to be solved by the invention are to be required for carbon dioxide when being used for existing phosphine generator
Gas dilutes the present situation of the concentration of the phosphine gas of generation, there is provided one kind easily produces, inexpensive, and Non-combusting gas dilute
The method of the concentration of phosphine gas.
A kind of phosphine gas of the invention produce and using and nitrogen dilution system, the phosphine gas produce
Include power supply, phosphine generator, source nitrogen (various nitrogen making machines, small nitrogen, elevated pressure nitrogen with use and nitrogen dilution system
Gas cylinder or tank), connecting line and control valve, pressure sensor, nitrogen gas purity detector, phosphine concentration detector, alarm
And protection circuit；
The phosphine generator provides the phosphine gas that aluminum phosphate medicament is produced with water reaction；
It is higher than 98.5% that the source nitrogen (various nitrogen making machines, small nitrogen, high-pressure nitrogen bottle or tank) provides purity
Nitrogen；
The connecting line and control valve are used to connect source nitrogen, phosphine generator and grain depot circulation fumigating system.
Preferably, the phosphine generator can be shown in that fragment is counted and control system, the patent No. 201210374239.6.
It has the function of controlling the aluminum phosphate unit interval to feed intake quantity.
The beneficial effects of the present invention are：
(1) nitrogen is generally nonflammable and does not support burning, meets as the condition of diluent gas, plays safety in production
Effect.
(2) nitrogen produce it is easier than carbon dioxide because nitrogen (N2) accounts for 78%, carbon dioxide in air
(CO2) 0.03% is accounted for.
(3) nitrogen making machine can be minimized.
(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 basic unit's grain depot application.
(4) illustrate
