      射流在高速前进过程中，在分散器内高速旋转的作用下，具有较高的角速度，使射流具有较强的穿透力，使微小气泡在水中气浮行程远，增强搅拌、推流与增氧能力。

     本设备能使泥水与空气在射流器内产生较高的负压和强烈的紊动、搅拌、剪切，促使液膜与气膜高频振荡，负气泡直径大幅度减小，气浮数量增多，增大气泡的比表面积，同时也负气液膜变薄，能极大地降低传质阻力，使氧分子更好地从气相转移到液相。 　　

     运行时，水泵叶轮在潜水电机带动下高速旋转，将泥水混合物推入射流器形成射流，在射流附近产生负压区，将空气通过吸气管吸入射流喷嘴负压区，在射流器的喉管内进行气、水、泥充分混合，又通过射流器的扩散管将射流的动能逐步转变成压能后进入散流器。在散流器内，气、水、泥混合物进一步混合，迫负气体继承剪切、破碎摧毁并气浮，绝大部门氧充分溶解于水中。同时，在射流流体压力的作用下，射流携带氧分子和微小气泡，从散流器的喷嘴中倾斜向下喷出、扩散，形成对水体和对生化池底部污泥冲击、搅拌后，由池底缓缓上升至水面，微气泡在水中停留时间一般长达30秒以上，使空气中的氧充分被溶解和吸收，进步了氧转移效率和充氧能力。 　　

     潜水射流曝气机由潜水泵、射流器、散流器、吸气管和软管五部门组成，如下图所示。在传统射流机理基础上融合了提高前辈的散流技术，采用射流曝气方式。 　　

Jet in high speed process, under the action of the distributor in the high speed rotating, has the high angular velocity, jet has strong penetrating power, visit the tiny air bubbles in water, enhance stirring, pushing flow and aerobic capacity.

This equipment can make the muddy water and air to produce high negative pressure in the jet device and strong turbulence, mixing, shearing, prompting liquid film and gas film high-frequency oscillation, greatly reduce the diameter of bubble, bubble number increase, increasing the specific surface area of bubbles, and at the same time just stubbornly thin liquid film, can greatly reduce the mass transfer resistance, better make oxygen from gas phase to the liquid phase. Running, the water pump impeller under the submersible motor drive at high speed, push the mud mixture into the jet formation of jet, the negative pressure zone, near the jet of air through the suction jet nozzle negative pressure zone, the jet flow within the pipes, gas, water, mud mix, and through the diffusion of jet pipe jet kinetic energy into pressure energy gradually after entering the diffuser. Within the diffuser device, gas, water and mud mixture mixing, further forced negative gas inheritance shearing, crushing destroy and emulsification, ensure that the department fully dissolved oxygen in water. At the same time, under the action of jet fluid pressure, jet carrying oxygen molecules and the tiny bubbles and tilted downward from the nozzle to the scattered jet, diffusion, formation of water body and the impact of biochemical bottom sludge, mixing, from the bottom up gently to the surface of the water, tiny air bubbles in the water residence time is generally more than 30 seconds, make the oxygen in air was dissolved and absorbed adequately, advances the oxygen transfer efficiency and oxygen filling ability. Diving jet aerator composed of submersible pump, jet, diffuser, air suction pipe and hose of five departments, as shown in the figure below. On the basis of traditional jet mechanism combines improve predecessors diffuser technology, adopts the jet aeration method.
