喷嘴的技术要求Technical requirements for nozzles
喷嘴的布置要求 Nozzle layout requirements
喷嘴布置的间距应合理，要使喷嘴喷出的锥形水雾相互搭接，不留空隙，否则烟气可能接触不到也低就从空隙中溜走，调整喷嘴布置密度和喷淋层数，可获得不同的喷雾重叠度。重叠度越高，脱硫效率也就越高，但阻力也会增加。一般喷雾重叠度为200%-300%,同时喷嘴布置的另一要求是不冲刷塔壁，喷淋母管和支撑件（未避免塔壁防腐材料，可将吸收塔外圈喷嘴布置90°或者涡流实心锥喷嘴)。
The spacing of the nozzles should be reasonable. The conical water mist sprayed from the nozzles should be overlapped with each other, leaving no gaps. Otherwise, the flue gas may not touch the droplets and slip away from the gaps. Adjust the nozzle placement density and the number of spray layers. Different spray overlaps are available. The higher the degree of overlap, the higher the desulfurization efficiency, but the resistance will also increase.Generally, the spray overlap is 200%-300%, and another requirement of the nozzle arrangement is not to wash the tower wall, spray the mother tube and the support member(the tower wall anti-corrosion material is not avoided, the nozzle of the outer ring of the absorption tower can be arranged 90°or Vortex solid cone nozzle).、
喷嘴的角度Angle of the nozzle
喷雾角是指浆液离开喷嘴口后形成的液膜锥的锥角，主要受喷嘴孔半径、旋转室半径和浆液入口半径等因素影响。选择喷雾角时，必须与喷嘴在塔内布置相结合，保证塔内覆盖均匀度与覆盖率，通常要求喷淋角为90°-120°。
The spray angle refers to the cone angle of the liquid film cone formed after the slurry leaves the nozzle port, and is mainly affected by factors such as the nozzle hole radius, the radius of the rotating chamber, and the radius of the slurry inlet. When selecting the spray angle, it must be combined with the nozzle arrangement in the tower to ensure uniform coverage and coverage within the tower, usually requiring a spray angle of 90°to 120°.
喷嘴的压力Nozzle pressure
喷嘴的喷嘴压降是指浆液通过喷嘴通道时所产生的压力损失，主要与喷嘴结构参数和浆液粘度等因素有关。压降越大，系统能耗也越大。一般喷淋系统喷嘴压降典型值为0.05-0.15MPa之间。
The nozzle pressure drop of the nozzle refers to the pressure loss generated when the slurry passes through the nozzle passage, which is mainly related to factors such as nozzle structure parameters and slurry viscosity. The greater the pressure drop, the greater the system's energy consumption. Typical nozzle system pressure drop is typically between 0.05and0.15Mpa.
喷嘴的流量Nozzle flow
喷嘴流量指单位时间内通过的体积流量，喷嘴流量与喷嘴压力降、喷嘴结构参数等因素有关。在相同喷嘴压力降条件下，喷嘴孔半径越大，喷嘴流量越大。
The nozzle flow rate refers to the volume flow rate through the nozzle per unit time, and the nozzle flow rate is related to the nozzle pressure drop and the nozzle structure parameters.Under the same nozzle pressure drop condition, the larger the nozzle hole radius, the larger the nozzle flow rate.
喷嘴的流量最终将影响脱硫系统的经济性，在给定的吸收塔中，选用流量大的喷嘴可以减少所需喷嘴的总数，从而降低系统的造价，大流量喷嘴的限制少且防堵塞性能好，这样可有效地节约运行和维护费用。但选用大流量嘴也有所牺牲，其液滴尺寸要増大，所以不同喷嘴可接受的最大流量度受到这种喷嘴雾化效果的限制。
The flow rate of the nozzle will ultimately affect the economics of the desulfurization system.In a given absorption tower, the nozzle with a large flow rate can reduce the total number of nozzles required, thereby reducing the cost of the system. The limitation of the large flow nozzle is small and the anti-clogging performance is good. This can effectively save operating and maintenance costs. However, the use of large flow nozzles has also been sacrificed, and the droplet size is increased, so the maximum flow rate acceptable for different nozzles is limited by the atomization effect of such nozzles.
平均粒径及雾滴粒径分布 Average particle size and droplet size distribution
喷嘴的雾化性能取决于浆液进口压力、浆液的黏度、表面张力和喷嘴结构参数等。当喷嘴进口压力越大，喷嘴压力降越大，通过喷嘴的流量越大，而喷嘴雾化浆滴平均直径越小。
The atomization performance of the nozzle depends on the slurry inlet pressure, slurry viscosity, surface tension and nozzle structure parameters. The greater the nozzle inlet pressure, the greater the nozzle pressure drop, the greater the flow through the nozzle, and the smaller the average diameter of the nozzle atomized slurry.
喷嘴的喷雾雾滴粒径分布对于多数应用都很重要，对于湿法脱硫系统更是有非常重要的意义。对于某一特定的工况而言，脱硫塔内的雾滴粒径有一个最优值。如果喷出与最优值粒径均匀度很高的雾滴，就能减少投资及实现系统的经済运行。
The spray droplet size distribution of the nozzle is important for most applications and is of great importance for wet desulfurization systems. For a particular operating condition, the particle size of the droplets in the desulfurization tower has an optimum value.If a droplet with a uniform particle size uniformity can be ejected,the investment and economic operation of the system can be reduced.
自由畅通直径 Free and unobstructed diameter
自由畅通直径是指喷嘴允许通过球形杂质的最大直径。自由畅通直径越大，其防堵塞的性能越好。
The free unobstructed diameter refers to the maximum diameter of
the nozzle that allows passage of spherical impurities.The larger the free diameter,the better the anti-clogging performance.
