Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is reactor body construction schematic diagram.
Each part numbers are expressed as in figure：1st, reactor body, 2, water-bath cooling pipe, 3, flexible hybrid air chamber, 4,
Pressurizer, F, one way stop peturn valve, a, b, c, d are four openings of reactor body respectively.
Embodiment
Referring to accompanying drawing 1 and Fig. 2, the utility model includes reactor body 1 and water-bath cooling pipe 2.The top of reactor body 1
Three openings a, b and c, respectively container of the grafting equipped with the concentrated sulfuric acid and sodium nitrite solution, and import the NO gases generated
Water-bath cooling pipe 2, the lower side position opening d connection waste collection pipes of reactor body 1.The importing or export of these liquid, can
To be operated by corresponding knob.
During preparation, using the top two of reactor body 1 opening a, b, the concentrated sulfuric acid and sodium nitrite solution are continuously injected into respectively,
Upper opening c connection water-bath coolings pipe 2 is used for the NO gases for discharging generation, and reactor body lower part side position opening d is used to discharge
Waste reaction solution.Insertion pH analyzers in reactor body 1, the pH value of detectable response liquid, and on this basis, to reaction solution
The dump valve of addition valve and waste liquid is controlled accordingly.It is continuously added to reaction solution, you can continuously generate NO gases.
The NO gases of generation need to first pass through water-bath cooling pipe 2, utilize the NaOH particles in the gas passage of water-bath cooling pipe 2
Remove the NO being mixed with NO2, the purpose of water-bath is to reduce the temperature of output gas, because this reaction is exothermic reaction, generation
Gas temperature it is higher, could normal storage and use so must cool.
NO gases enter flexible hybrid air chamber 3, it is therefore an objective to using the elasticity of flexible hybrid room, stabilizing gas pressure, carry out
Buffering, make gas production rate output steady.NO gases enter pressurizer 4 by flexible hybrid air chamber 3 again, are carried out by gas pressurized pump
Pressurization, gas is set to keep the pressure of setting, being capable of normal use to supply laboratory.
