The import of pipeline and pollutant handling arrangement connects, and the outlet of pollutant handling arrangement is communicated with external environment, and air pump is separately connected to
Power supply.Tiny structure is presented when the present invention is air-introduced machine gas bleeding in tank, volatile materials in oil storage tank is promoted constantly to wave
Hair increases the tolerance of pernicious gas in atmosphere, increases the loss of oil product；
The file that the number of applying for a patent is 200320107373.6 discloses " light oil recovery apparatus for oil tank ", by motor, pressure
Contracting machine, light oil short-term training tank composition, it is characterised in that light oil short-term training tank is cylindrical, and top is equipped with liquid-seal type or mechanical
Breather valve, the row's of being internally provided with formula coil pipe or disc type coil pipe or spiral coil, bottom are equipped with and big tank spiracle or manhole
The flange of connection, bottom top are equipped with a top liquid collecting umbrella directed downwardly, and the light of a connection light oil tank is equipped at top of the umbrella
Matter oil recovery tube, the coil pipe in rapid-result light oil short-term training tank are connected with compressor.The power device and oil tank of the utility model
It is close, there are Explosive risk, and the non-purified i.e. discharge of remaining exhaust gas, can also pollute air.
Summary of the invention
Goal of the invention: traditional Tank's Breather Valve is overcome to discharge exhaust gas not pollution administration air or be difficult to administer lack
It falls into, provides one kind for multiple oil storage tanks in tank field, the compressed air provided using safety zone is as multiple Tank's Breather Valves
Waste gas recovery and administer power source device.
Technical solution: a kind of Tank's Breather Valve emission-control equipment provided by the invention, for handling Oil Tank Area
The exhaust gas of the breather valve discharge of one or more oil storage tanks.Containing air compression station, (safety zone far from Oil Tank Area is arranged, whole
A tank field uses an air compression station.The air compression station is needed to purify air, cool down, is dehydrated, is compressed.Compression is empty
Gas station is a set of with automatic control system, automatically and reasonably adjusts each sky according to each Tank's Breather Valve exhaust gas tolerance and content
The tolerance of gas source waste gas recovery deodorization device), each oil storage tank tank deck or tank periphery setting preseparator, second-stage separator,
Aoxidize deodoriser, absorbing and deodorizing device；Separately there are exhaust pipe, air pipe line.Exhaust gas from breather valve discharge after, by exhaust pipe according to
It is secondary to flow through preseparator, second-stage separator, oxidation deodoriser, absorbing and deodorizing device, it is then discharged in air；Compressed air is from pressure
The outflow of contracting air station, by air pipe line followed by second-stage separator, preseparator, is then discharged in air.
Exhaust pipe in preseparator and second-stage separator is one section of exhaust gas coil pipe, in preseparator and second-stage separator
Air pipe line be one section of air-coil.Air-coil previous conviction connects expansion valve, accelerates cooling, exhaust gas coil pipe and air-coil energy
Heat exchange is enough carried out, the compressed air of cooling cools down to exhaust gas.Exhaust gas temperature in second-stage separator be reduced to subzero 5-30 degree (compared with
Light hydro carbons condenses liquefaction separation), the condensate liquid reflux liquid reserve tank or flow back into oil storage tank again that exhaust gas coil pipe generates；Pre-separation
The exhaust gas temperature of device is reduced to subzero 0-10 degree (heavier hydro carbons condensation waterization separation), and the condensate liquid that exhaust gas coil pipe generates is predominantly cold
Condensate is discharged into outside oil storage tank, is not polluted substantially.
The exhaust gas flowed out from second-stage separator flows into oxidation deodoriser, and the oxidizing removal part wherein being had has
Poisonous gas；Then, absorbing and deodorizing device is flowed into from the exhaust gas that oxidation deodoriser flows out, the adsorbent wherein being had is adsorbed and removed remaining
Under most of toxic gas.Consumptive material in oxidation deodoriser, absorbing and deodorizing device can be replaced manually.
It is connected with temperature sensor on exhaust pipe, air pipe line, and connects with automatic control system and man machine operation interface
It connects, the exhaust gas temperature control that can be discharged according to each Tank's Breather Valve flows through the respectively arranged preseparator pressure of the oil storage tank
The switch of the compressed air regulating valve of contracting air control valve and second-stage separator realizes accurate automatic testing and control, guarantees regulation
Effect and reduction energy consumption.
There is three-level separator between the preseparator and second-stage separator, flows through the temperature of exhaust gas in three-level separator
Control obtains the different condensate liquids of corresponding adiabatic condensation temperature in subzero 10-20 degree.The waste liquid of different set points is separated, is subtracted
The separating-purifying treatment process in few later period.
When the pressure that pressure sensor detects breather valve is greater than atmospheric pressure, starting air compression station or open connection should
The pipeline valve of oil storage tank；When less than atmospheric pressure, the pipeline valve for connecting the oil storage tank is shut down or closed.
The utility model has the advantages that
By using technology of the invention, portion can be made to be converted into condensate, and (in two steps, heavy hydrocarbons first liquefy, lighter hydrocarbons
Liquefy after class, inexpensive quick separating, energy consumption is lower), remaining foul smell is purified improvement.The recovery technology solves abhiseca
Exhaust gas gas collection problem and the increase of bring security risk and operating cost due to gas collection.It can ensure that the peace of oil storage tank tank field
Entirely, so that resource is obtained reuse, protect environment, reduce carbon emission.
The device also has a characteristic that
It is mounted at the top of each oil storage tank or the recycling deodorization controlling device on periphery is without using electrical source of power, the energy needed for recycling is dynamic
Power source carries out improvement purification from compressed air, gas in the device, does not need additional power source.Entire tank field uses
One pneumatically operated station.
Since the gas of single tank body volatilization is less, 100~1000m3/h for the treatment of capacity, each tank deck or periphery are mating a set of
Tank deck waste gas recovery processing unit does not need to increase collecting pipe system, reduce due to collecting pipe bring security risk
And cost of investment.
Air compression station is a set of with automatic control system, automatic according to each Tank's Breather Valve exhaust gas tolerance and content
The tolerance of each air-source waste gas recovery deodorization device is reasonably adjusted, guarantees the reasonable efficient operation of system.The gas of breather valve exhalation
Amount is bigger, and the amount of compressed air is bigger, and the value of the exhaust gas of recycling is invested back much larger than the value of the compressed air consumed
The receipts phase is short.
After through the condensate recycling device of multiple tracks, exhaust gas concentration is gradually reduced, and exhaust gas tolerance is also greatly decreased.This
Sample, the methods of traditional biological deodorizing, ion deodorization, chemical deodorizing, physical absorption can be used to handle the foul smell in we.Phase
For traditional waste gas treatment process, which is not necessarily to the power consumption of additional process, without a large amount of
The consumption of the consumptive material of oxidant or adsorbent.
