我公司專業(yè)生產(chǎn)銷售氣浮機(jī)刮吸泥機(jī)氣浮氣浮設(shè)備砂濾罐本文由www.shdzbanchang.cn提供
氣浮機(jī)射流在高速前進(jìn)過程中，在分散器內(nèi)高速旋轉(zhuǎn)的作用下，具有較高的角速度，使射流具有較強(qiáng)的穿透力，使微小氣泡在水中行程遠(yuǎn)，增強(qiáng)攪拌、推流與增氧能力。
本氣浮機(jī)設(shè)備能使泥水與空氣在射流器內(nèi)產(chǎn)生較高的負(fù)壓和強(qiáng)烈的紊動、攪拌、剪切，促使液膜與氣膜高頻振蕩，負(fù)氣泡直徑大幅度減小，氣泡數(shù)量增多，增大氣泡的比表面積，同時也負(fù)氣液膜變薄，能極大地降低傳質(zhì)阻力，使氧分子更好地從氣相轉(zhuǎn)移到液相。
運(yùn)行時，水泵葉輪在潛水電機(jī)帶動下高速旋轉(zhuǎn)，將泥水混合物推入射流器形成射流，在射流附近產(chǎn)生負(fù)壓區(qū)，將空氣通過吸氣管吸入射流噴嘴負(fù)壓區(qū)，在射流器的喉管內(nèi)進(jìn)行氣、水、泥充分混合，又通過射流器的擴(kuò)散管將射流的動能逐步轉(zhuǎn)變成壓能后進(jìn)入散流器。在散流器內(nèi)，氣、水、泥混合物進(jìn)一步混合，迫負(fù)氣體繼承剪切、破碎摧毀并氣浮乳化，絕大部門氧充分溶解于水中。同時，在射流流體壓力的作用下，射流攜帶氧分子和微小氣泡，從散流器的噴嘴中傾斜向下噴出、擴(kuò)散，形成對水體和對生化池底部污泥沖擊、攪拌后，由池底緩緩上升至水面，微氣泡在水中停留時間一般長達(dá)30秒以上，使空氣中的氧充分被溶解和吸收，進(jìn)步了氧轉(zhuǎn)移效率和充氧能力。
潛水射流曝氣機(jī)由潛水泵、射流器、散流器、吸氣管和軟管五部門組成。在傳統(tǒng)射流機(jī)理基礎(chǔ)上融合了提高前輩的散流技術(shù)，采用射流曝氣方式。
Jet in high speed process, under the action of the distributor in the high speed rotating, has the high angular velocity, the jet has strong penetrating power, the journey far 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, liquid film and gas film high-frequency oscillation, greatly reduce the diameter of bubble, bubble number increase, increasing the specific surface area of bubbles, at the same time also angrily thin liquid film, can greatly reduce the mass transfer resistance, make the oxygen from the gas phase to the liquid phase better. 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 is air through the suction 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 after step by step into the diffuser. Within the diffuser device, gas, water and mud mixture mixed further, forced negative gas inheritance shearing, crushing destroy and emulsification, guarantee 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 retention time average 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.
