针对市面上增氧装置体积大,能耗高等问题,笔者根据射流泵技术原理设计了一款微气泡增氧装置。装置主体分为4个部分,并通过试验确定了装置4个部分的最优参数组合。结果表明：液体流量为4.23 m3/h,装置喉嘴距为40 mm,喉管长为120 mm时,增氧效果最佳,其溶氧量为11.23 mg/L,超过了试验水温度为12℃时的饱和溶氧量10.83 mg/L,达到超饱和状态。装置增氧效果明显,且结构简单,体积小,因此该装置在水产养殖、污水处理、农业增氧灌溉等领域中具有广阔的应用前景。

Aiming at the large volume and high energy consumption of the existing aerators, we designed a micro-bubble aerator based on the principle of jet pump technology. The main body of the device was divided into four parts, and the optimal parameters of these parts were determined by experiment. The results showed that when the liquid flow was 4.23 m3/h, nozzle-to-throat clearance was 40 ram, and throat-pipe length was 120 mm, the optimum oxygen-adding effect could be obtained. In this case, the dissolved oxygen amount in the water was 11.23 mg/L, ...
