Operation principle and product advantage
Circulation fluid curtain Paint spraying platform in the circulation fluid curtain low-temperature plasma photocatalysis exhaust treatment system is by recycle liquid pump 1-11 work, make and hold among the 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 form curve whirlpool liquid curtain, stop effectively for the first time and do not adhere to coated article in the 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 curtain, 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 form curve whirlpool liquid curtain, secondary effectively stops the part paint viscosity that does not adhere to coated article in the construction and has been blocked with efflorescence and crosses once particle, is stopped again 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 back road organic waste gas treatment device handles the needed cleaning of waste gas.
The organic exhaust gas of discharging from blower fan 1-3 air outlet enters into road, back organic waste gas treatment device by pipeline and further waste gas is handled.
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 lacquer cleaning that swims in liquid bath 1-9 of isolation.
The liquid that 1-12 holds in the liquid case when temperature is lower than zero degree can adopt anti-icing fluid.
The operation principle that engineering project begun newly circulation fluid curtain spraying platform organic exhaust gas is handled 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, effectively isolated the part that does not adhere to coated article in the construction to N road liquid curtain plate and painted sticky particle for one of circulation, 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.
It is that existing spraying equipment is needed the demand of waste gas pollution control and treatment and the organic waste gas treatment device that designs that the circulation fluid curtain spraying platform organic exhaust gas that has formed construction status is handled the operation principle of putting.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, effectively isolated the part that does not adhere to coated article in the construction to N road liquid curtain plate and painted sticky particle for one of circulation, 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 with the organic exhaust gas of sticky particle thing after handling 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 by ozone oxidation carbon dioxide and water, the small-sized organic molecule group that is not decomposed fully, enter the photodissociation cleansing phase, by wavelength ultraviolet ray scission of link, forming carbon dioxide and water twin-stage purifies, guaranteed the purification up to standard of spraying organic exhaust gas, the gas of discharge reaches country's " discharge standard of air pollutants ".
