The design principle of water sprayer is as follows:
As it is shown in figure 5, the spacing of nozzle and mixing tube import is with L1=0.5d2(d2For mixed tube diameter) time, efficiency is the highest；Mixed
Close length of tube L2Be advisable equal to 6 times of mixed tube diameters, i.e. L2=6d2, can reduce to not less than 4 times of mixed tube diameters as made difficulty；
Mixing tube should smooth with shell connecting line；Anemostat angle [alpha]2It is advisable with 5 °；The import direction angle beta sucking filtrate with 45 °～60 ° is
Preferably, angle line and blast tube crossing point of axes are preferably before nozzle；Nozzle convergence angle θ can be with 10 °～30 °.Processing installation requirement is as follows:
1. the import of nozzle mixing tube and internal diameter anemostat internal diameter machined surface roughness should reach Ra3.2；Must be concentric when nozzle and mixing tube are installed,
Axiality should reach 9～10 grades of accuracy class；Water sprayer is strictly on guard against gas leakage when installing.
The design of water sprayer calculates
(1) nozzle: straight length diameter d ' at nozzle entrance0M () is 2.5～3.5m/s calculating by in-pipe flow speed, length is to meet
Installation requirement is limited, and W is amassed in jet area0(m2) can be calculated as follows
Q in formulaaThe flow of air, m3/s；
μ discharge coefficient, takes 0.95；
H ozzle resistance drop (10kPa), if water intaking pressure is 400～450kPa (gauge pressures), induction chamber pressure is
50kPa (absolute pressure), then h is 450～500kPa (absolute pressures).
By WoThe diameter d of nozzle exit can be calculated0, length δ of straight length=d at this0/ 2, as nozzle and collapsible tube
Between gap.Such as nozzle cone angle0Take 75 °, then nozzle Taper Pipe segment length L0For,
(2) mixing tube: mixing tube sectional area W2With W0Only ratio general satisfaction W2/W0=2/1, then mixed tube diameter
Its length L2M () presses L2=Kd2Calculating, COEFFICIENT K takes 10～20.
(3) collapsible tube: the distance of nozzle Taper Pipe end to the mixing mouth of pipe should be equal to the spray penetration of nozzle, this length=δ+L1=
0.5d0ctgα0, therefore contracted length L1=0.5d0(ctgα0-1).If collapsible tube cone angle is α1(taking 30 °), then shrink bore
d1=d2+2L1tgα1。
(4) anemostat: set anemostat cone angle as α3, its sectional area W3With W2Only ratio is for 2:1, then its diameter
It is longα3Take 15 °.
(5) water sprayer suction chamber sectional area
Suction chamber should have enough volumes, makes gas unblocked with filtrate, and its sectional area can be calculated (r ' in figure by bow-shaped area
Mean outer radius for nozzle), as shown in Figure 6,
R suction chamber radius, m in formula.
