The working principle of the oxygen generator, the principle and function of the oxygen generator

The main performance indicators of the aerator are specified as the aeration capacity and power efficiency. Aeration capacity refers to the amount of oxygen added by an aerator to a water body per hour, measured in kilograms-hour; Power efficiency refers to the amount of water oxygenation consumed by an aerator for 1 kilowatt hour, and the unit is kilogram kilowatt hours. For example, the power efficiency of the kilowatt water wheel aerator is kilogram kilowatt hours, which means that the machine consumes 1 kilowatt hour of electricity and can add kilograms of oxygen to the water body.

Although the use of aerators in aquaculture production is becoming more and more widespread, there are still some fishery practitioners who do not understand its working principle, type and function, and it is blind and random in actual operation. Here it is necessary to understand how it works first, so that you can master how to use it in practice. As we all know, the purpose of using an aerator is to add dissolved oxygen to the water body, which involves the solubility and dissolution rate of oxygen.

Solubility includes three factors: water temperature, water salt content, and oxygen partial pressure. The dissolution rate includes three factors: the degree of unsaturation of dissolved oxygen, the contact area and mode of water-gas, and the movement of water. Among them, the water temperature and the salinity of the water are a stable condition of the water body, which is generally unchangeable, and the degree of unsaturation of dissolved oxygen is the factor we want to change, and it is also a condition that currently exists in the water body. Therefore, in order to realize the aeration of water body, it is necessary to directly or indirectly change the partial pressure of oxygen, the contact area and mode of water and gas, and the movement of water.

In view of this situation, the measures taken when designing the aerator are:

1) The use of mechanical parts to agitate the water body to promote convective exchange and interface renewal;

2) Disperse the water into fine droplets and spray them into the gas phase to increase the contact area of water and gas;

3) Inhalation under negative pressure to disperse the gas into microbubbles and press it into water.

The different types of aerators are designed and manufactured according to these principles, either by one measure to promote the dissolution of oxygen, or by two or more measures.

Disassemble the fish tank aerator and understand how it works.

The principle of the aeration pump is as follows:

When the impeller rotates, due to centrifugal force.

role, weather vane.

It causes the gas to move forward and outward, resulting in a series of spiral movements. The air between the impeller blades rotates in a spiral and squeezes the gas from outside the pump body into the side grooves (drawn in from the suction port), and when it enters the side channel, the gas is compressed and then reverts to the impeller blades and re-accelerates again.

As the air passes through the impeller and side grooves along a spiral track, each impeller blade increases the degree of compression and acceleration, and as the rotation progresses, the kinetic energy of the gas increases, causing the pressure of the gas to pass along the side channel to increase further. When the air reaches the connection point between the side trough and the discharge flange (the side channel narrows at the outlet), the gas is extruded out of the vane and discharged from the pump body through the outlet muffler.

Uses of aeration pumps:

The aeration pump is a kind of ventilation air source for blowing and purging, which is mainly used for paper cutter, combustion deaeration machine, roll machine filter forming machine, electroplating tank liquid stirring, atomization dryer, fish aeration and aeration, water treatment explosion, screen printing machine, photographic plate making machine, automatic feeding machine, liquid filling machine, powder filling machine, Changlin Dongfeng machine, electric welding equipment, film machinery, paper conveying, cleaning of dry cleaning clothes, etc.

Precautions for purchasing aeration pumps:

1. Simply understand the strength scale of the first business: registered capital.

The scope of business, the company is to obtain the necessary certificates.

2. The company's corporate background, historical performance and growth: whether the company's actions are legal and standardized.

3. Whether the reliability, quality assurance and after-sales service of the product are perfect: whether the product has passed CE certification.

ROSH certification, SGS certification, etc.

4. Whether the logistics is timely, the payment method, etc.

Hello dear! I am glad to answer for you, and the principle and function of the Sakura oxygen concentrator are as follows:1

The basic principle and the basic principle that makes up the chemical oxygen generator (Oxylite) is that peroxide is decomposed in water by the action of a catalyst to form oxygen. Its basic composition is a generator (Qipu generator type) and peroxide denier (medicine). Among them, the generator includes a water tank and a valve, and the accessories include an oxygen inhalation tube and an oxygen mask.

The characteristics of this model are: small size; Low cost; Rapid oxygen production; Easy to use and easy to carry; Low noise. The disadvantages are:

It is not suitable for long-term use, and there is a certain ***. Medical and health care oxygen generators can be divided into three types according to different oxygen production methods, namely, molecular sieve pressure swing adsorption oxygen generator, membrane separation oxygen generator and electrolyzed water oxygen generator. What it does:

The main principle of the oxygen inhaler is to concentrate the oxygen in the air and provide sufficient oxygen for the human body, so it has many effects on the human body. After inhaling oxygen, it can provide oxygen to the brain, play a role in eliminating fatigue and improving intelligence, and can also improve the body's immunity.

Home oxygen concentrators are easy to use, light to move, and suitable for medical staff. The vehicle dual-purpose type can be suitable for home use, and can also be used in the car by using the car's teasing power supply. Oxygen is a colorless and odorless gas that is an important substance for the human body and other animals and plants.

Without oxygen, nature would be lifeless and lifeless. It is as important as water. It has a wide range of applications and is inseparable from oxygen in all walks of life, including medical and cosmetology.

The working principle of the household oxygen generator: using the molecular sieve physical adsorption and desorption technology, the oxygen generator is filled with molecular sieve, which can adsorb nitrogen in the air under pressure, and the remaining unadsorbed oxygen is collected and purified into high-purity oxygen. When the molecular sieve is depressurized, the adsorbed nitrogen is discharged back into the ambient air, and at the next pressurization, the nitrogen can be sipped to be adsorbed and produce oxygen.

The whole process is a cyclical and dynamic cyclic process, which does not consume molecular sieves. Oxygen concentrators are suitable for oxygen therapy and oxygen health care:1.

Respiratory diseases: pneumonia, bronchitis, chronic bronchitis, viral respiratory infections, asthma.

Emphysema, cor pulmonale, etc. 2.Cardiovascular and cerebrovascular diseases: hypertension.

Heart disease, coronary heart disease, myocardial infarction.

Cerebral thrombosis, cerebral ischemia, vertigo.

atherosclerosis, etc. 3.Plateau hypoxia:

High-altitude pulmonary edema, acute high-altitude illness, chronic high-altitude illness, high-altitude coma, high-altitude hypoxia, etc. 4.People who are prone to hypoxia:

Middle-aged and elderly people, pregnant women, students who have been engaged in mental work for a long time, company employees, ****; People who have been engaged in underground or confined space operations for a long time, people who are overworked, and who have insufficient oxygen supply, etc. 5.Other people who need oxygen therapy:

Weak immunity, heat stroke.

People with gas poisoning, drug poisoning, etc.

The general principle of the oxygen concentrator is:The principle of the oxygen machine is to use air separation technology, first compress the air with high density, and then use the different condensation points of each component in the air to separate the gas and liquid at a certain temperature, and then further distill.

The working principle of the household oxygen concentrator: the use of molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen.

The molecular sieve discharges the adsorbed nitrogen back into the ambient air when the pressure is reduced, and the nitrogen can be adsorbed and oxygen can be produced during the next pressurization, and the whole process is a periodic dynamic circulation process, and the molecular sieve is not consumed.

In order to save money, we must pay attention to the maintenance of the home oxygen concentrator, first choose a reasonable oxygen inhalation time.

For patients with severe chronic bronchitis and emphysema, with clear abnormal lung function and persistent partial pressure of oxygen below 60 mm Hg, oxygen therapy should be given for more than 15 hours a day.

For some patients with no or only mild hypoxemia, short-term oxygen administration can reduce the discomfort of "shortness of breath" during activity, tension or exertion. The oxygen in the oxygen cylinder cannot be exhausted, and it is generally necessary to leave 1MPa to prevent dust impurities from entering the bottle when refillingNasal cannulas, nasal prongs, humidification bottles, etc. should be disinfected regularly.

The frame element negative oxygen machine uses the air as the raw material, and adjusts the oxygen concentration of the air through the intelligent molecular sieve, which is calcined at high temperature.

The amount of oxygen in water decreases as the temperature increases. Specifically, the higher the temperature, the lower the oxygen content in the water, and the lower the temperature, the higher the oxygen content in the water. For example:

20 liters of water, 100 liters can dissolve 3 liters of oxygen, when the temperature drops to zero, 100 liters of water can dissolve 5 liters of oxygen.

The higher the temperature of the water, the faster the metabolism and respiration rate of fish and aquatic organisms, the more oxygen content is required than usual, and the oxygen content in the water will naturally decrease. If there is less oxygen in the water, the activity of the fish will be weakened, and the fish will directly surface to breathe the oxygen in the atmosphere in order to cope with the low amount of oxygen, which is often called "floating head".

The amount of dissolved oxygen is related to the depth of the water. Because oxygen is infiltrated from the atmosphere through the surface of the water, the slower the penetration rate is, and the internal pressure of the water is not lower than the atmospheric pressure, so the oxygen content that penetrates into the deep layer is very small, which is why the principle that the water is too deep when we raise fish is not beneficial, and it is better to have a water depth of 2 or 3 meters, because the oxygen content in the water at this depth is very high.

The amount of oxygen in the water is related to the area of the water. The larger the surface area of the water, the higher the oxygen content, and the smaller the surface area of the water, the lower the oxygen content. Therefore, under the same conditions, the probability of fish in a small water surface "turning over (pan) pond" is much greater, for example, a large water surface like a lake will not have a "flipping (pan) pond".

Fluctuations in the water surface cause changes in the oxygen content of the water. For example, when the wind blows, the waves on the surface of the water are in contact with the air, and the undulating wave area is larger than the surface area of the normal still water. Therefore, when the wind blows, the oxygen content in the water is higher than usual.

Therefore, people say that "the wind blows the water, and the water moves the fish" refers to the situation at this time.

In fact, the aerator dissolves the air (oxygen) into the water according to the principle that the fluidity of the water and the contact with the air will increase the oxygen content in the water"Waves"and then absorbed into the water body.

The principle and function of the oxygen generator are: its principle is to use air separation technology. First, the air is compressed at a high density, and then the condensation of each component in the air is used to separate the gas and liquid at a certain temperature, and then the distillation is carried out to separate it into oxygen and nitrogen.

In general, because it is mostly used to produce oxygen, people are used to calling it an oxygen concentrator. Due to the wide range of oxygen and nitrogen applications, oxygen generators are also widely used in the national economy.
