Compared with prior art the utility model has the characteristics that and beneficial effect：
1st, the showering of the utility model large area soil suitable for Practical Project, is not used as small range local
Experiment or exploration；Because the repaired area of large area soil is big, in soil the concentration of VOC it is extremely uneven,
The substantial amounts of contaminated underground water of doping and the composition of pollutant and it is distributed extremely complex in soil, therefore large area soil repaiies
It is multiple and its difficult, therefore gas phase of the present utility model extracting cleaning system has in actual applications obvious technical advantage.
2nd, the utility model has purification and the dual-use function for detecting, the collection of various data and detection function, is meeting
Beyond gas phase extracts cleaning system to the needs of data message, may also provide and give soil remediation technologist detailed soil gas
The data message of composition and concentration, allows users to more accurately carry out process practice, before being soil remediation process free
The situation that theory is ripe, practice is blank.
3rd, in pipeline air or nitrogen are filled with as needed, are filled with air in main line and VOC is entered
Row dilution, is filled with air and nitrogen in indirect regeneration, also for VOC is diluted, prevents from waving
The concentration of the property sent out organic gas reaches dangerous values, so as to ensure that gas phase extracts the safety work of cleaning system.
4th, gas phase extracting cleaning system of the present utility model is to be automatically controlled to be by a whole set of linkage of control system control
System, without the need for professional's operation.
5th, refrigeration machine is connected on gas-liquid separator；Because during real work, what extracting came up from soil is not only
VOC, while also have the underground water being contaminated also can be come up by a large amount of extractings, and if to reach volatility
The effect of organic gas purification, just has to be completely separated VOC and waste liquid before into cleaning treatment system
Open, dry VOC is sent in cleaning treatment system and is processed, otherwise not only do not reach purification standard, instead
And the paralysis of cleaning treatment system can be caused；And waste liquid can be sent in water treatment system by bilge well after being separated and be located
Reason；Therefore connect refrigeration machine on gas-liquid separator and accelerate air-liquid separation, strengthen gas-liquid separation effect, it is ensured that dry enough
Dry VOC enters cleaning treatment system；
6th, using two sets of indirect regeneration alternations, the saturation cycle of activated carbon adsorption bed absorption is extended.
7th, the effect of surge tank：Cushioning effect is primarily served, will be reduced by the gas flow rate that extraction system conveying comes, allowed
The more stable entrance cleaning system of gas, is conducive to purified treatment below；While in order to prevent deposit such as water or solid
Body particulate matter enters cleaning treatment system, separately sets pipeline and connects with sewage draining exit, but this blowoff line is not main blowdown
Channel, main blowdown channel is to enter sewage well through liquid-phase treatment system.
8th, in cleaning treatment system, the effect on the nitrogen inlet duct road in indirect regeneration：It is a kind of safeguard measure, and
It is not involved in technique.Because the content of the VOC of gas is highly unstable and irregular follows in soil
, so when being suddenly increased to dangerous values if there is the concentration of VOC（Explosion limit）, system can rush automatically
Enter nitrogen to be diluted；In addition nitrogen is also prevented from after activated carbon saturation, future as the protection system of activated carbon adsorption bed
Obtain and be used as when recovering displacement to use, in a word, the effect on nitrogen inlet duct road is to prevent VOC concentration from becomeing greater to danger
Danger value.
9th, for cleaning treatment system, prior art has type a lot, and purification type described in the utility model is also special
For large area soil remediation, and the purification of the VOC of density unevenness weighing apparatus, it should be noted that volatility has
When machine gas concentration is lower, on the contrary easily purification discharge is not up to standard, and this cleaning treatment system is exactly for grinding that this situation is done
Send out.
10th, current existing technology blind spot：All technologies all concern cleaning treatment system purification efficiency, while all stopping
The experimental stage is stayed in, the practical application of large area soil remediation was not done；And our technology be from extraction system extract when
Just have begun to administer VOC, allow gas to be easier to be administered in extractive process, while this practicality
New technique specially tackles the various complex situations that large area soil is brought.
The utility model can be widely applied to the gas phase extracting cleaning system of gas.
