增氧设备氧气锥增氧锥用于循环水养殖

产品简介

    氧气锥也叫增氧锥。是一种为工厂化水产养殖设计而成的一种增氧设备。通体采用FRP

高强度材料制成。增氧效果明显超出同类产品。与纯氧产生设备（或氧气瓶）等其它循环水养殖设

备配套使用，可对密度的水产养殖提供高溶氧水。

产品研发初衷

    由于循环水养殖越来越普及，水产养殖密度也越来越高，继而对水体溶氧值的要求也越来越

高。以35公斤/立方的南美白对虾养殖密度为例，溶氧量要至少达到16mg/L以上才可以满足鱼类的

需求。这个溶氧值还不包括水中的化学需氧量、其它生物需氧量等。因为高密度水产养殖的水体

含有大量的饵料及未来得及清除的鱼类的粪便等有机物，这些有机物分解也会消耗大量的氧气。

而传统的增氧方式如空气曝气等已无法达到这个水平。利用纯氧通过强有力的方式增加水中溶解

氧量已成为市场的迫切需求。

产品结构

    氧气锻采用玻璃钢（高强度玻璃纤维复合树脂）喷熔缠绕而成。整体呈现上小下大的锥体

结构。进出水采用PVC法兰连接。底部有排污口及观察窗。

使用方法

    氧气锥是一种特殊的压力容器。它的主要功能就是在气液充分混合的条件下，增加压力来

迫使气体克服水的表面张力而被动溶解。因此氧气锥要与增压泵、射流器等设备配套使用。气

源采用制氧机或氧气瓶（氧气纯度大于90%）

影响出水溶氧值的因素

    与气体在水中的溶解度相似，氧气在水中的溶解度与温度、压强等有关。再次就是与

气液混合的方式有关。而在正常的压强条件下，传统的增氧方式会使水体溶氧有一个上限。如

果是用空气作为气源，溶氧量会进一步得到限制。采用工业纯氧（纯度超过90%）则使溶氧效

率大大增加。氧气锥与纯氧组合使用，再利用射流原理将氧气和水充分混合。在气液接触面积

呈现指数倍级增加时，增加水体的压强。使出水溶氧量更进一步得到巩固和加强。

氧气锥应用范围

    大型工厂化水产养殖场、海水育苗场、大型水产暂养基地、海洋馆、水族馆等。

产品使用条件

    工作压力为0.25MPa,出厂测试压力为0.4MPa.可用于海水等弱腐蚀性液体环境中。

规格型号及参数

Product introduction

    Oxygen cone is  a kind of equipment that add oxygen which in water. It's body 

using FRP high strength material. Obvious effects of increasing oxygen than 

similar products. With pure oxygen generating equipment (or oxygen bomb) and other

 circulating water aquaculture, aquaculture of ultrahigh density may be provide 

high dissolved oxygen water.

Product research and development purpose

    It's more and more popular because of the circulating water aquaculture, 

aquaculture density is higher and higher, which in turn is becoming more and more 

high to the requirement of dissolved oxygen concentration values. To 35 kg/cubic

 South America white shrimp breeding density, for example, oxygen should be at least 

16 mg/L above can meet the needs of fish. The dissolved oxygen value does not include 

the chemical oxygen demand (cod) in the water, and other biological oxygen demand 

(cod) and so on. Because of the high density of aquaculture water body contains a lot

 of bait before and remove the fish waste and other organic matter, the organic 

matter decomposition will consume large amounts of oxygen. The traditional way of 

increasing oxygen such as air aeration have been unable to reach this level. Using

 pure oxygen through a powerful way to increase the water dissolved oxygen has

 become the urgent needs of the market.

Product structure

    Oxygen cone is made of  glass fiber reinforced plastic (high strength glass fiber

 composite resin) spray melting winding. Present the small under large pyramidal 

structure. In and out of the water use PVC flange connection. The bottom outlet

 and the observation window.

Method of use

    Oxygen cone is a special kind of pressure vessel. Its main function is under 

the condition of gas-liquid mix, increasing pressure to force to overcome the 

surface tension of the water gas and passive dissolution. So oxygen cone to form a 

complete set of equipment, such as booster pump, jet device to use. Air using oxygen

 generator and oxygen bomb oxygen purity (greater than 90%)

The factors influencing water dissolved oxygen value

    Similar to the solubility of a gas in the water, the solubility of oxygen in 

the water first related to temperature, pressure, etc. Once again, is associated

 with the way of gas-liquid mixing. And under the condition of normal pressure, the 

traditional way of increasing oxygen will make the water dissolved oxygen has a limit.

 If is to use air as gas source, dissolved oxygen will further restrictions. Using

 the industrial pure oxygen (purity over 90%) increase the dissolved oxygen efficiency

 greatly. Oxygen cone and pure oxygen combination use, reusing principle of jet oxygen 

and water mix. Present index in gas liquid contact area times the level increases, the

 increase of water pressure. The water dissolved oxygen further consolidated and strengthened.

application range

    Large factory aquaculture farms, seawater farms, large aquatic temporarily raising

 base, aquarium, aquarium, etc.

Conditions of use

    Working pressure is no more than 0.25 MPa, the factory test pressure of 0.4 MPa.

 Can be used in weak or corrosive liquid of water.
