The size of described exhaust vent is F=V/ ω, and F is exhaust vent area m ², V is outlet air quantity m ³/ h, ω is air-flow velocity w, wherein local resistance formula Δ P is local resistance Pa, and ρ is gas density kg/m ², ξ is coefficient of partial resistance.

Because fan outlet dynamic pressure is larger, flow velocity ω=12.5 meter per second of air outlet, after being provided with plenum chamber, make kinetic energy progressively be converted into potential energy, make the static pressure in casing increase, make the flow uniform distribution of the each wind outlet in plenum chamber bottom need to realize balance air-out by inhomogeneous perforate.

In plenum chamber, flow process is for typically " Variable Mass Flow "---being accompanied by flow velocity progressively changes at each point, each point static pressure in plenum chamber is different, make each air outlet flow uniform distribution on air outlet, needs by inhomogeneous perforate, adjust perforated area, with the air quantity of balance outlet.

According to local resistance formula:

$\mathrm{\ΔP}=\mathrm{\ξ}\frac{{\mathrm{\ω}}^2\mathrm{\ρ}}{2}$

Due to F ₁area is greater than F ₂aperture area, make their local resistance Δ P ₁=Δ P ₂must be ${\mathrm{\ΔP}}_1={\mathrm{\ξ}}_1\↑\frac{{{\mathrm{\ω}}_1}^2\↓{\mathrm{\ρ}}_1}{2}={\mathrm{\ξ}}_2\↓\frac{{{\mathrm{\ω}}_2}^2\↑{\mathrm{\ρ}}_2}{2}={\mathrm{\ΔP}}_2,$ The flow that just can reach each point by changing the coefficient of partial resistance ξ in each cross section and flow velocity ω equates.

Can find out from CFD model 1, if do not installed wind deflector additional, air outlet 1 has dead angle, and air quantity minimum, air outlet 5, 6, 7 air-out wind speed maximums, and in the bottom of cloth wind screen, almost do not detect wind speed at dead angle place, more than highest point can reach 6m/s, this is owing to there is no wind deflector, the wind speed of fan outlet directly strikes the bottom section of cloth wind screen, arrive the minimizing of bottom air speed and brought static pressure rising (kinetic transformation is potential energy), therefore the air-out flow in the larger region of pressure is just large, otherwise flow is just little, cause cloth wind screen air outlet pressure distribution inhomogeneous, and then cause air outlet assignment of traffic inhomogeneous, and the basic reason causing to be the speed of air-flow fast and the rectilinear motion of air-flow, and there is no good tune wind water conservancy diversion, therefore wind deflector is installed in plenum chamber exit, the flow velocity of even each air outlet and flow to a certain extent.

From CFD model 2, can find out, install the velocity flow profile of cloth wind screen after wind deflector additional, contrast model 1 can find that whole air outlet uniformity is significantly improved, and outlet wind speed concentrates on certain interval and thoroughly solved air-out Dead Core Problems, and the uniformity of cloth wind screen has obtained remarkable improvement.

Can find out that from CFD model 2 the high wind speed in cloth wind screen exit can reach 4.8m/s, because air-flow is to do straight line convergent mode of motion by certain speed, if do not install wind deflector additional, the direction of motion that does not change fluid just can not make in curing room, there is an air-flow stably, for ensureing that all pole plates have an identical curing environment, therefore this product has installed wind deflector additional on cloth wind screen.Different operation stages should have different air-flows, adopts fan frequency conversion technology to ensure maximum quantity of wind and the minimum balanced air-flow of curing reaction stage of drying stage.
