Utility model content
It can not be discharged and Failure analysis instrument oxygen in time for the cooling device cooling water of ABB gas analysis meters in the prior art
Table causes the deficiencies such as the generation of gas leakage, and the technical problems to be solved in the utility model, which is to provide one kind, can avoid gas leakage
Gas analysis meter cooling system.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of gas analysis meter cooling system of the utility model, including sample gas disposal unit, pumping cells, analyzer list
Member, exhaust unit and control unit, sample gas disposal unit have sample gas cylinder, dust removal and filtration dress device, heater and cooling
Device, sample gas cylinder is connected with dust removal and filtration dress device, and heated device enters cooling device, and the cooling device is cooled down using nitrogen
Device, its gas output interface is connected to pumping cells；The signal input of temperature sensor and control unit inside nitrogen cooler
End connection, the signal output of control unit is connected in the actuating mechanism controls loop of nitrogen cooler flow solenoid valve.
Waterproof filter is added between pumping cells and analysis meter unit.
It is characterized in that waterproof filter is：Drier fillter section is added in its internal gas passage.
The utility model also has recovery unit, including recovery pipe and the recovery pump that is installed in recovery pipe, one
End is connected with exhaust unit, and the other end is connected with coal gas temporary storage tank, then is stored up by the magnetic valve selection on pipeline with qualified coal gas
Tank is connected or connected with gas tank.
The utility model has the advantages that and advantage：
1. the utility model uses nitrogen cooler, its sealing is far superior to original refrigerator, can avoid an oxidation
Carbon is revealed and is poisoned, and reduces spare part expense, easy to maintenance succinct.
2. the utility model is through secondary dehumidifying, it is ensured that drying property of the coal gas before analysis meter unit is entered, it is to avoid
Damage the risk of instrument.
3. the utility model has installed coal-gas recovering unit additional, 1.5 ten thousand are about reclaimed per stove and is stood, the wave of resource is effectively prevent
Take.
Brief description of the drawings
Fig. 1 is the utility model system structure diagram.
Embodiment
As shown in figure 1, a kind of gas analysis meter of the utility model, including sample gas disposal unit, pumping cells, analysis meter
Unit, exhaust unit and control unit, sample gas disposal unit have sample gas cylinder, dust removal and filtration dress device, heater and cold
But device, sample gas cylinder is connected with dust removal and filtration dress device, and heated device enters cooling device, and the cooling device is using nitrogen cooling
Device, its gas output interface is connected to pumping cells；The signal input of temperature sensor and control unit inside nitrogen cooler
End connection, the signal output of control unit is connected in the actuating mechanism controls loop of nitrogen cooler flow solenoid valve.
The utility model also has waterproof filter, is installed between pumping cells and analysis meter unit；In waterproof
Drier fillter section is added in filter interior gas passage.
The utility model also has recovery unit, including recovery pipe and the recovery pump that is installed in recovery pipe, one
End is connected with exhaust unit, and the other end is connected with qualified gas holder by magnetic valve selection or connected with gas tank.
In the utility model, sample gas by dedusting, heat, after the dewater treatment that cools, into aspiration pump, by aspiration pump
Give flowmeter, then second dehydration carried out through waterproof filter, oxygen gauge, carbon monoxide table into analysis meter unit and
Carbon dioxide table is analyzed, and parameter is sent into control unit (using PLC) after the completion of analysis, indicates coal-gas recovering.
In the present embodiment, the cooling of sample gas is changed to be cooled down with nitrogen cooler, and closed-loop control, temperature are carried out by control device
Degree can be adjusted between 5~10 degree, and condensation effect is more preferable, it is easy to which moisture is separated out.
In nitrogen cooler, the damp and hot high temperature nitrogen from nitrogen pot is reduced to certain temperature by nitrogen cooler cooling
Moisture in degree, high temperature nitrogen is because dew point reduction is precipitated, and moisture is discharged through gas-liquid separator, and the nitrogen after cooling is recycled
Use.Coal gas of high temperature is after nitrogen cooler, and moisture is also precipitated, and more dry coal gas is by pumping pumped.
Due to using nitrogen cooler, the risk that the poor coal gas of sealing of refrigerator is easily revealed is evaded.The utility model exists
Waterproof filter is added again between pumping cells and analysis meter unit, secondary remove is carried out before analysis meter unit is entered
It is wet, make the coal gas drying property into analysis meter unit good, extend the service life of all kinds of instrument；Coal inside waterproof filter
The drier fillter section that sets in gas passage is integral removable assembling structure, is convenient for changing.
The utility model also has recovery unit, including recovery pipe and the recovery pump that is installed in recovery pipe, one
End is connected with exhaust unit, and the other end is connected with coal gas temporary storage tank, then is stored up by the magnetic valve selection on pipeline with qualified coal gas
Tank is connected or connected with gas tank.
The utility model has added recovery unit, and the coal gas given off from analyzer is reclaimed, coal gas is first delivered to
In temporary storage tank, if the result of analyzer output shows that gas composition is qualified, by control device by coal gas temporary storage tank and finished product
Magnetic valve between gas tank on pipeline is opened, while the sample pneumatic transmission that booster air pump detects this batch is into finished pot.Conversely,
If gas composition is unqualified, the magnetic valve between coal gas temporary storage tank and gas tank on pipeline is opened by control device, together
When the booster air pump sample pneumatic transmission that detects this batch to the medium processing to be purified of gas tank, until reentering finished product after the assay was approved
Tank.
