Full problem.Existing way is substantially filled with object gas into mixing duct or blending tank using sequence, according to different component
Partial pressure controls the ratio of configuration.It is such there is no corrosion or combustibility if the gas property of each component is stablized
Mode is feasible.But if being used for special gas, such as inflammable and explosive, high toxicity or strong oxidizing property gas are just extremely dangerous.It presses
According to related regulation, fluorine gas is unable to pure simple substance and fills, transports and use, it is necessary to be mixed into other inert gases to reduce ability after risk
Use, if directly mixed with pipeline, need to fluorine gas pressurize, misoperation or have leakage will cause fluorine gas burning or occur quick-fried
It is fried；It being mixed with blending tank, volume is excessive, if mixing other inert gases after also pressurizeing to fluorine gas using usual method, by
In the special nature of fluorine gas, other gases are filled in the fluorine gas of elevated pressures, it is possible to which compressed fluorine causes it to divide
Rise, is easy layering, brings great security risk.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of new-type fluorine gas and inert gas are mixed
It attaches together and sets, the above-mentioned deficiency of the prior art can be overcome.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of new-type fluorine gas and inert gas mixing arrangement, including tank body, tank body top are equipped with safety valve, in the middle part of tank body
Be equipped with and air inlet one and draw sample mouth, draw the opposite side that sample mouth is located at air inlet one, the lower part of tank body is equipped with gas outlet and air inlet
Two, tank base is equipped with bracket.
Preferably, the tank interior is equipped with nozzle, and air inlet one is connect by pipeline with nozzle.
Preferably, the lower part of tank body is equipped with temperature-measuring port.
Tank body is for containing mixed gas；Air inlet one is inert gas air inlet；Safety valve is safety device, can be prevented
Charge pressure is out of control to cause danger；Nozzle can make inert gas with injecting type air inlet, be conducive to be uniformly mixed；Gas outlet is for connecing pumping
Empty set system, and as gaseous mixture gas outlet；Temperature-measuring port installs temperature transmitter, for detecting tank body temperature；Draw sample mouth to be used for
Connect pressure gauge and analytical sampling pipeline；Air inlet two is fluorine gas air inlet, and bracket is used to support tank body.
The utility model uses negative pressure hybrid mode, will first vacuumize in tank body, then be passed through the pure fluorine gas purified, remembers
Record increased fluorine gas partial pressure in tank body, partial pressure of the increased numerical value of pressure as fluorine gas in tank body, it is desirable that be filled with tank body after fluorine gas
Interior pressure keeps negative pressure state in tank body still less than atmospheric pressure；It is then passed through rapidly using mode of jet and needs mixed inertia
Gas, controls the growth of pressure in tank body, and partial pressure of the value added of pressure as inert gas utilizes the change of mixing pressure inside the tank
Change converses the amount that mixed phase answers gas, and mixed ratio of the dividing ratios as two kinds of gas reaches pressure needed for configuration proportion
Mixing is completed afterwards；It reuses isolation film vane compressor gaseous mixture is filled in pressure vessel.
The utility model has the beneficial effects that the compressed possibility of fluorine gas can be reduced by the easily controllable flow of negative pressure inlet
Property, and then the safety of operation is improved, and gas can quickly be spread, be conducive to mixing more evenly；Gas access uses in tank body
Nozzle arrangements, the sprayable formula outflow of air-flow, can accelerate gas mixing；The mountable temperature transmitter of temperature-measuring port detects temperature in tank body
Degree, improves the safety of operation.

In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
The use of this gas mixer is related to the operating procedures such as displacement, evacuation, distribution, can be fast safely by flow operations
Being filled with, mixing for the completion gas of speed, can be used for general mass industrial production, concrete operations are as follows:
1) prepare before mixing: will be taken out in blending tank using vacuum system device external on the gases exit line of blending tank
Sky removes the foreign gases such as a large amount of air in tank；
2) it is filled with the inert gas to be mixed of certain pressure into tank, then is evacuated, so repeatedly repeatedly with displacement
Blending tank reaches and further removes remaining foreign gas in tank, guarantees that the quality of safety and gaseous mixture when being filled with fluorine gas is wanted
It asks；
3) blending tank is evacuated to higher vacuum degree again, can mix more gases by blending tank after repeatedly replacing；
4) fluorine gas purified being slowly filled with into blending tank by fluorine gas admission line, pressure inside the tank starts to go up,
Valve is closed when close to concora crush to be terminated to be filled with fluorine gas, and the numerical value that pressure inside the tank goes up is as the amount and partial pressure for being filled with fluorine gas, negative pressure
It is filled with fluorine gas under state, the safety of operation can be improved；
5) inert gas is filled with into blending tank by air inlet pipe, is required according to the dividing ratios of gaseous mixture, controlled in tank
The numerical value that pressure goes up, completes the mixing of gas, when being filled with inert gas, keeps being in bleed pressure and flow, blending tank
Low-pressure state, not needing higher pressure can be filled with, and the nozzle arrangements in tank can allow the air inlet of inert gas injecting type, to fluorine
The mixing of gas and inert gas is played the role of " stirring ", can quickly spread and mix with fluorine gas, not will lead to the layering of gas.
In conclusion, by the easily controllable flow of negative pressure inlet, can be subtracted by means of the above-mentioned technical proposal of the utility model
The small compressed possibility of fluorine gas, and then the safety of operation is improved, and gas can quickly be spread, be conducive to mixing more evenly.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
