Shore micro nano aeration device pontoon nano bubble machine micro nano aeration machine

working principle RWP micro nano bubble machine is composed of nano bubble pump, dissolved gas system, release system, etc. RWP micro nano bubble machine mixes the gas and water through the nano bubble pump and inputs them into the gas dissolving tank to dissolve the gas in the water. Then, the dissolved gas is released through the gas releasing device to form nano bubbles, which are injected into the water at a high speed. The jet has a mechanical ionization effect on the water, breaking the colloidal connection of polluting groups While breaking the chemical bond and electrical adsorption of pollutants and water, the injected reactive oxygen species,oxygen ions, hydrogen ions and hydroxyl ions produced by ionization oxidize and decompose pollutants, so as to realize the purification of water quality. The dissolution rate of micro nano bubbles in water exceeds 85%, and the dissolved oxygen concentration can reach above the saturation concentration. Moreover, micro nano bubbles are stored in water for a long time in the form of bubbles, which can continuously supplement active oxygen to the water with the consumption of dissolved oxygen,providing sufficient active oxygen and strong oxidizing ion groups for microorganisms purifying and treating sewage, And ensure sufficient reaction time of reactive oxygen species. For the reduced clean water treated by RWP series nano bubble machine, the dissolved oxygen content standard in the water is 4ppm, and the purification capacity of the water itself is much higher than that under natural conditions. Scope of use It is used in water restoration, sewage treatment, aquaculture, ships, drag reduction, etc. PH value of medium: 6.5 ~ 8.0, medium temperature ≤ 50 ℃ Definition of micro and nano bubbles Usually, we call the existence of gas in liquid as bubble. The formation of bubbles can be encountered in many processes in nature. When the gas is subjected to shear force in the liquid, bubbles of different sizes and shapes will be formed. At present,the classification and definition of bubbles are not very strict. According to the order from large to small, bubbles can be divided into centimeter bubbles (CMB), millimeter bubbles (MMB), micron bubbles (MB), micro nano bubbles (MNB) and nano bubbles (NB). The so-called micro nano bubbles refer to bubbles with a diameter of about 10 microns to hundreds of nanometers when bubbles occur. This kind of bubble is between micron bubbles and nano bubbles and has physical and chemical properties that conventional bubbles do not have. Structure introduction 1. Outlet pipe joint Connect the outlet pipe joint with a hose or hard pipe to transport the dissolved air water from the atomizer to the treated water area in the river. 2. Bubble atomizer Release the high-pressure dissolved air water in the pressure tank through pressure loss and atomize it into bubbles with a diameter of less than 20 μ M fine bubbles, high-pressure saturated dissolved air water also becomes low-pressure excellent Soluble air and water. 3. Atomizer maintenance valve In case of blockage and other faults of the atomizer, the atomizer can be repaired by closing the valve. 4. Pressure tank It is made of stainless steel. Under the combined action of pressure in the tank and rotating water flow, the gas-water mixture turns into supersaturated high-pressure dissolved gas-water. The special structure of the tank makes the dissolved gas effective Guoda reach Good. 5. Integrated two-phase flow air dissolver A special structure is used to suck in air and water at the same time. After the initial crushing of the impeller, the gas-liquid mixed liquid is formed and transported to the pressure tank. The power is a specially designed special submersible motor. The motor is coaxial with the pump head. The motor is installed in the pressure tank, the pump head is installed outside the pressure tank, and the pump head and motor are sealed respectively; Even if the seal of the pump head is damaged, the liquid will flow directly to the outside without entering the motor cavity to damage the motor. 6. Water inlet regulating valve Considering the different installation heights of the equipment, the pressure in the pressure tank, the dissolved air volume generated by the aerator and the air-water ratio will change. The air-water ratio will reach (only in the second stage) through the joint adjustment of the inlet regulating valve and the inlet control valve Commissioning at one startup). 7. Inlet pipe joint connect the inlet pipe joint with hose (with certain rigidity and can withstand 0.05Mpa negative pressure) or hard pipe to transport the water in the river to the two-phase flow dissolved gas machine. 8. Intake control valve Adjust the air intake. Combined regulation with water inlet control valve to achieve Good gas water ratio. 9. Return water pipeline Connect two flow dissolved gas machines and pressure tank. 10. Bleed safety valve When the pressure in the tank is too high (more than 0.7MPa), the safety valve will open automatically for pressure relief; When the air ratio in the tank is too high (at this time, the dissolved air water from the atomizer contains large bubbles), manually open the safety valve to discharge the air in the pressure tank. 11. Pressure gauge It is used to observe the pressure value in the pressure tank in order to adjust the pressure value in the tank.
