Operation principle and product advantage
Circulation fluid curtain Paint spraying platform in circulation fluid curtain spraying organic waste gas treatment system is by recycle liquid pump 1-11 work, make and hold in liquid case 1-12 liquid and deliver to circulation fluid case one 1-24 by circulation fluid pipe 1-14 and flow to liquid curtain plate one 1-6 by overfall one 1-5 and form curtain, flow to the dentation curtain along a 1-7 by liquid curtain plate one 1-6, unit length moment increase and deflector one 1-8 forming curves whirlpool liquid curtain, effectively stop for the first time and do not adhere to coated article in construction and partly paint sticky particle, what do not stop also makes it efflorescence.Working procedure is along with secondary cycle liquid curtain carries out once again like this, to be liquid deliver to circulation fluid case two 1-25 by circulation fluid pipe 1-14 flow to liquid curtain plate two 1-18 by overfall two 1-19 and forms curtains, flow to the dentation curtain along two 1-17 by liquid curtain plate two 1-18, unit length moment increase and deflector two 1-16 forming curves whirlpool liquid curtains, secondary effectively stops the part paint viscosity that does not adhere to coated article in construction and has been blocked with efflorescence and crosses once particle, is again stopped and efflorescence.Through stopping of liquid barrier 1-21 and netted replaceable division board 1-22, in principle efflorescence lose the sticky paint particulate blockage, guaranteed that rear road organic waste gas treatment device processes the needed cleaning of waste gas.
The organic exhaust gas of discharging from blower fan 1-3 air outlet enters into rear road organic waste gas treatment device by pipeline and further waste gas is processed.
Liquid bath overfall 1-20 designs for guaranteeing the required normal liquid level of circulation fluid curtain spraying platform work, because the aqueous vapor that air quantity is carried secretly when the psychrometric difference of liquid bath and surrounding environment and work makes it to be in evaporation and minimizing state.Fluid infusion mouth 1-27 designs for increasing required liquid measure, and clean-up port 1-23 will be blocked the residual paint cleaning that swims in liquid bath 1-9 of isolation.
When the temperature liquid that 1-12 holds in the liquid case during lower than zero degree can adopt anti-icing fluid.
The operation principle of engineering project begun newly circulation fluid curtain spraying platform VOCs treatment is: casing can provide the spraying environment as required, centrifugal fan or in line blower fan provide the wind-force that needs for spraying application, circulation together effectively isolated the part paint sticky particle that does not adhere to coated article in the construction to N road liquid curtain plate, make it to lose viscosity and become powdery, through water fender and netted replaceable division board barrier, provide the organic exhaust gas of not being with the sticky particle thing for organic waste gas treatment device.
Having formed operation principle that the circulation fluid curtain spraying platform VOCs treatment of construction status puts and being needs the demand of waste gas pollution control and treatment and the organic waste gas treatment device that designs to existing spraying equipment.Operation principle is: former gas outlet taps into the casing air inlet, centrifugal or direct blower fan is that emission-control equipment is supplied needed wind-force, circulation together effectively isolated the part paint sticky particle that does not adhere to coated article in the construction to N road liquid curtain plate, make it to lose viscosity and become powdery, through water fender and netted replaceable division board barrier, for organic waste gas treatment equipment provides not organic exhaust gas with the sticky particle thing.
Do not enter organic exhaust gas low-temperature plasma and photocatalyst emission-control equipment 3 with the organic exhaust gas of sticky particle thing by connecting pipe 2 after processing by circulation fluid curtain Paint spraying platform 1, the organic exhaust gas micel is under the low-temperature plasma splitting action, with the open loop of triphen scission of link, be decomposed into subset, namely become carbon dioxide and water by ozone oxidation, the small-sized organic molecule group that is not decomposed fully, enter the photodissociation cleansing phase, by length ultraviolet line scission of link, form carbon dioxide and water twin-stage and purify, guaranteed the purification up to standard of spraying organic exhaust gas.
Enter organic exhaust gas active-carbon treating apparatus 4 through the organic exhaust gas after machine waste gas low-temperature plasma and 3 processing of photocatalyst emission-control equipment and carry out the charcoal absorption VOCs treatment, belong to low-temperature plasma+UV photocatalyst purified treatment compensation process, through processing gas up to standard through the regulation high altitude discharge.Operation principle is: active carbon is a kind of porous carbon containing matter, it has highly developed hole structure, the loose structure of active carbon provides a large amount of surface areas for it, can fully contact with gas (impurity), thereby given active carbon peculiar absorption property, made it be very easy to reach the purpose that absorbs collection impurity.As magnetic force, all has attractive interaction between all molecules.Just because of this, a large amount of molecule on the active carbon hole wall can produce powerful gravitation, thereby reaches the purpose that will harmful impurity attracts in the aperture.
Vapour phase oxidation process organic waste gas treatment device 5 carries out the compensation process that DORC vapour phase oxidation process VOCs treatment is low-temperature plasma and UV photocatalyst purified treatment, charcoal absorption VOCs treatment.
DORC vapour phase oxidation process operation principle: in vapour phase oxidation process organic waste gas treatment device 5, the water that is used for exhaust-gas treatment is solvent, is equipped with oxydol H
2O
2Form composite absorbent liquid with DORC, DORC is that water white multiple high molecular polymerization organic solvent and catalyst, oxidant synthesize.The oxydol H that strong oxidability is arranged
2O
2Produce chain and pass reaction, oxydol H under the synergy of DORC
2O
2All be cleaved into two along weak bond and produce a large amount of strong oxidizing property hydroxyl radical free radicals with not matching only electronics gene in the working solution high speed, make the organic molecule Quick Oxidation in waste gas become carbon dioxide and water.
Method by spray, organic solvent, catalyst, the oxidant of DORC-multiple high molecular polymerization are effectively absorbed poisonous, the harmful gaseous pollutant that flows in air, quick catalysis transforms and is converted into salt lipoidis innocuous substance, guaranteed the purification up to standard of spraying organic exhaust gas, the gas of discharge reaches country's " discharge standard of air pollutants ".
