Description
Technical field
Patent of the present invention is related to a kind for the treatment of tank source and blocks the capping of VOCs volatilizations, more specifically a kind of
Modular connects liquid formula treatment tank source and blocks VOCs dissipation cappings entirely.
Background technology
At present, cesspool and sewage treatment facility use outdoor open by design substantially, therefore sewage and atmospheric environment are straight
Contact, in sewage disposal process, has substantial amounts of escaping gas to be emitted in air, including sewage is in itself containing substantial amounts of
One of the sulfur-nitrogen compound that volatile organic matter and biochemical reaction are produced, principal element as environmental degradation.It is national in recent years
Environmental protection is more paid attention to, many environmental regulations have been put into effect,《GB31570-2015 petroleum refining industry pollutant emission marks
It is accurate》In, the requirement of other Environmental capacities is explicitly pointed out：For collecting defeated, storage and handling containing volatile organic matter, odorant
Wastewater facilities should be closed, and the waste gas of generation should access organic exhaust gas and reclaim or processing unit.At present, for sewage treatment plant VOCs
Processing it is main take the theory first volatilized, administered afterwards, and existing VOCs processing methods technological process is long, and operating cost is high, makes
With short life, the replacement cycle is short (if having), there is certain security risk, therefore processing reliability value must be discussed.
The capping of VOCs volatilizations is blocked in treatment tank source can specialty solution cesspool volatile organic matter dissipation
Problem, is that a kind of modular connects fluid-tight convering system entirely, according to American Standard API650 standards, can be carried out according to cesspool concrete condition
Targeted design, makes the capping of API floating plates to measure, blocks VOC generation, reaches that source solves VOCs discharges and asked
The effect of topic.
Being sealed on the full liquid Installation Modes that connect above cesspool helps to reduce the less turbulence of sewage, reduces whole system
Reynolds (Reynold's) criterion (Re), three phase separation resistance coefficient is increased, so as to improve three phase separation speed and fully improve cesspool
Outdoor operation present situation；Capping is operationally without using water, electricity and gas wind equal energy source simultaneously, it is to avoid utility cost；And capping
Fault rate is relatively low, and maintenance mans' equipment is simple, and manual maintenance cost is relatively low, greatly reduces capping maintenance cost, is disposably throwing
Capital face is also below other existing techniques.
The content of the invention
In order to solve the above mentioned problem of prior art presence, the present invention proposes that one kind blocks VOCs volatilizations in treatment tank
The complete of loss connects the capping of liquid formula, can effectively solve the above mentioned problem of prior art.
VOCs volatilizations capping main member is blocked in treatment tank source of the present invention includes cellular module, double-layer seal
Circle, discharge outlet, upper lower baffle plate.Cellular module is body structure, inside sets honeycomb core, and cellular module is aluminium alloy or stainless steel
Protective layer is sprayed with matter, and plate, protective layer is made up of epoxy resin, adds its corrosion resistance；Prevent that ponding from assembling, in honeycomb
Discharge outlet is provided with above module, drainage channel is in capping lower liquid without any immersion part；Double-layer seal is provided with two ends
Device, device is made up of PU and the double-deck sponge of immersion type, and blending bolt is fixed, and increases seal, reduces VOCs loss；In sewage
Pool wall is provided with upper lower baffle plate, makes to be sealed in fixed region and moves up and down, and liquid level of fitting completely, has blocked cesspool
VOC loss.Size, the row of cellular module, according to American Standard API650 standards, can be designed according to the concrete condition for the treatment of tank
The position and two distances between plates of the position at the mouth of a river and quantity and upper lower baffle plate, make treatment tank source of the present invention block VOCs and wave
Diverging ease capping is fully achieved connects liquid entirely, so as to realize the loss for fundamentally blocking VOCs.
The discharge outlet is installed on capping center, is connect entirely on liquid formula floating plate to prevent capping top rainwater to be trapped in,
And drainage channel in floating plate lower liquid without any immersion part.
The double-deck foam seal, polyurethane sponge is cladded with using PU materials, is realized that the full liquid form that connects is sealed, is optimal
Sealing effectiveness；Secondary seal strengthens sealing effectiveness, and sewage VOCs dissipations are blocked comprehensively, watershed management is realized.
The corrosion-inhibiting coating, because there is synthetic chemistry corrosive substance in sewage, to avoid long-term immersion, in capping
One layer of epoxy novolac chemical preservation coating of system surfaces application, realizes anti-corrosion protection function, thickness of dry film is 0.25-0.30mm.
The upper lower baffle plate, is extreme case occur to prevent that closure system from running height, therefore set in cesspool inwall
There is upper lower baffle plate, to ensure that closure system is run in the range of effective controllable height.
And be sealed on the full liquid Installation Modes that connect above cesspool and help to reduce the less turbulence of sewage, reduce whole system
The Reynolds (Reynold's) criterion (Re) of system, increases three phase separation resistance coefficient, so as to improve three phase separation speed and fully improve sewage
The outdoor operation present situation in pond；Without using water, electricity and gas wind equal energy source during capping operation, it is to avoid utility cost；Cover fault rate
Relatively low, maintenance mans' equipment is simple, and manual maintenance cost is relatively low, capping maintenance cost is greatly reduced, in terms of one-time investment
Also below other existing techniques.
In summary, as a result of above-mentioned technological means, VOCs volatilizations are blocked in treatment tank source of the present invention
Capping is avoided that some problems of sewage disposal under existing technical background, fully improves the outdoor operation present situation of cesspool, and blocks and wave
The organic matter dissipation of hair property, solves the problems, such as cesspool emitting offensive odor, can effectively administer VOCs dissipations, realize environmental objective.
