Description
Technical field
The invention belongs to nitrogen preparation field, and in particular to the nitrogen gas generator of a kind of efficient, high-purity and high intelligence.
Background technology
Various sources of the gas are often used in Laboratory Instruments analysis, as liquid chromatograph mass spectrography (LC/MS) is extensive
Applied to fields such as biochemistry, medical research and application, environmental analysis, food analysis and clinical practices.Pass
System laboratory is typically to be realized using the steel cylinder or high pressure tank of low cost to LC/MS plenum system,
But limited because of its own gas capacity, Lab workers must not infrequently order, carry, install and change steel
Bottle (high pressure gas holder), this not only expends substantial amounts of human and material resources and time, or even makes some important experiment works
Work is forced to interrupt；High pressure gas holder stage automatic deflation pressure reducing protection is a kind of inevitable technological deficiency, also directly
Connect the fearless waste that result in user's gas resource；And steel cylinder often use up in the case of without obvious sign by nitrogen,
So as to cause the experiment of user's important analysis to be forced to stop.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of efficient, high-purity
The nitrogen gas generator of degree, high intelligence, the nitrogen gas generator is during nitrogen is prepared, moreover it is possible to provides the sky of purification
Gas.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of nitrogen gas generator, including air pretreatment unit, air cleaning member and nitrogen preparation unit, it is described
Air pretreatment unit include being sequentially connected air compressor machine, aerial condenser, steel cylinder components and except water filter,
Described steel cylinder components include at least two gas bombs being arranged in parallel, and described air cleaning member is by phase successively
Drier even and the first dust removal filter composition, described nitrogen preparation unit is by the hollow-fibre membrane that is sequentially connected
Air separator and the second dust removal filter composition, the air inlet of described drier and hollow-fibre membrane air separator
Mouth is connected with the gas outlet except water filter respectively.
The pressure switch for controlling air compressor machine to open and close, steel cylinder components are equipped with each gas bomb of steel cylinder components
Air inlet and gas outlet be equipped with check valve.
Described steel cylinder components include two gas bombs being arranged in parallel.
Described air pretreatment unit also includes unloading valve, draining valve and PLC, and described unloading valve is arranged on
On pipeline between steel cylinder components air inlet check valve and air compressor machine, described draining valve is arranged on the bottom of gas bomb
Portion, unloading valve and draining valve are connected with PLC by circuit, control the keying of unloading valve and draining valve.
Described air pretreatment unit also includes fan, and described fan is relative with aerial condenser, is arranged on sky
The outside of gas condenser.
Described aerial condenser is coiled tube condenser.
The described water filter that removes is that absorption type removes water filter.
Described drier is absorption type dryer.
Described the first dust removal filter and the second dust removal filter is absorption type dust removal filter.
After air compressor machine produces air, after aerial condenser and fan coolling cooling, gas enters steel cylinder components
In each gas bomb, when air compressor machine start and stop, had between steel cylinder components and aerial condenser
Gas is present, and at this moment just needs to empty this portion gas by unloading valve so that this part pipeline and atmospheric pressure
Pressure is close, so as to pressure and gas when pressure not enough drastically stops and avoids the air compressor machine from opening when avoiding air compressor machine from stopping
Close caused air compressor machine can not normally start in pipe.At the same time, cylinder assembly is entered by condensed gas,
Meeting residual fraction moisture in gas bomb, and the effect of draining valve is exactly periodically to arrange the water of gas bomb bottom
It is empty.The gas that moisture removes is divided into two-way gas by gas again via except water filter afterwards.All the way via drying
After device and dust removal filter reject the impurity of gas totally, the air of purification is provided for rearmounted experimental facilities.It is another
Road gas is adopted by hollow-fibre membrane air separator, is removed the oxygen in air with membrane separation process, pure nitrogen gas is again
Used after by deduster, the particulate matters such as dust are removed totally to post equipment.PLC controls unloading valve and draining
The keying of valve.And air compressor machine work is controlled by pressure switch, when some gas bomb in steel cylinder components
Interior air pressure is started working when being less than 100Psi, and air compressor machine stops when the air pressure in some gas bomb reaches 130Psi
Only work.
Compared with prior art, the invention has the advantages that：
(1) aerial condenser additionally increases fan, improves the efficiency of cooling.
(2) control draining valve and unloading valve, pressure switch to control air compressor machine by PLC, full-automatic control can be achieved
System.
(3) stability of supply, continuity are ensured using double cylinders.Double cylinders use parallel way, effectively
Increase space utilization degree, and increase gas tank capacity, so that the stability of output gas has necessarily with continuity
Guarantee.
(4) gas passes through water removal, drying process, improves the purity of gas.
