Description
Technical field
The utility model relates to a kind of automatic detection device, specifically relates to a kind of intelligentized flame ionization ditector.
Background technology
All there is such shortcoming in common flame ionization ditector at present, after experiment is done in the ventilation igniting, if gas circuit is cut off, needs the manual adjustments valve, and gas is turn-offed; During lower secondary point fire, need again manually to debug valve, so repeatedly bother very much.
Summary of the invention
The utility model is mainly to solve the existing technical matters of above-mentioned prior art, and a kind of intelligentized flame ionization ditector is provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of intelligentized flame ionization ditector, comprise the ionization chamber that is provided with electrode, be provided with the hydrogen flame-thrower nozzle in described ionization chamber, nozzle is provided with the emitter that the annular metal circle consists of, the ionization chamber internal upper part is provided with the collector that a metallic cylinder consists of, and forms ionizing electric field between two electrodes; Two electrodes are connected to amplifier, and amplifier is connected to data acquisition unit, and data acquisition unit is connected to controller; It is carrier gas passage under the hydrogen flame-thrower nozzle, the carrier gas inlet place of carrier gas passage is provided with the carrier gas solenoid valve, the other hydrogen passage that is provided with on carrier gas passage, the hydrogen inlet place of hydrogen passage is provided with the hydrogen solenoid valve, the wall body of the other ionization chamber of hydrogen flame-thrower nozzle is provided with air duct, the air intake place of air duct is provided with the air solenoid valve, and carrier gas solenoid valve, hydrogen solenoid valve and air solenoid valve are controlled by the solenoid control assembly, and the solenoid control assembly is connected on controller.
principle of work of the present utility model is: take hydrogen at combustion synthesis in air as the energy, carrier gas is generally nitrogen, utilizing nitrogen to carry tested component and combustible gas is that hydrogen enters inspection side device from nozzle, combustion-supporting gas is that air is led the people from surrounding, tested component is separated into positive and negative luxuriant son in flame, move to opposite polarity electrode separately in the electric field that the DC voltage of positive and negative luxuriant son 300V between two electrodes forms, the ion current that forms is collected the utmost point and collects, and with current signal transfer to amplifier, the data-signal that data acquisition unit collects after amplification is transferred to controller again, control the solenoid control assembly by controller according to data-signal, and then control solenoid valve break-make and the aperture of three road gases, and data-signal is processed.
The utility model has the advantage of to have substituted traditional manual debugging valve, automaticity is high, and stable performance is simple to operate, and cost is low.
