Kaijie Membrane Contactors:一、Large flow external pressure type degassing membrane;二、Internal pressure type degassing membrane;
一、Technology and application of the large flow degassing membrane
(一)．Structure diagram(High pressure resistant & External pressure type) Figure 1

(二)．Characteristics of the large flow degassing membrane：
1.By the technique of continuous control stretching,to precise control the porosity and pore size of the membrane;
2. Through the special hydrophobic treatment, according to the number of 2000 membrane silks as a bundle, the membrane hole into the pure water (pressure:0.30Mpa) are pre-detecting of membrane silks, pick out the broken hole membrane silks, to ensure the finished membrane silks permanent "breathable impervious";
3. The membrane silk after the special pre-detecting,using the special weaving process,making the membrane silks in the form of winding shape in the internal component,filling more uniform,gas / water contact surface effectively,and the degassing efficiency is greatly improved;
4. Packaged of membrane element, set the middle plate,making the gas/water on both sides of the contact more fully, the effect is better;
5. Packaged of membrane element, using the PE mesh grille to wrap membrane silk,to ensure that wont thrust membrane silks under high hydraulic pressure,and have a certain effect on the blocking flow,making contact with water and the gas phase membrane silk more uniform;
6.Liquid inlet temperature:about 25℃，pressure≤0.6Mpa;temperature:60℃，pressure≤0.2Mpa。

1.By the technique of continuous control stretching,to precise control the porosity and pore size of the membrane; 2. Through the special hydrophobic treatment, according to the number of 2000 membrane silks as a bundle, the membrane hole into the pure water (pressure:0.30Mpa) are pre-detecting of membrane silks, pick out the broken hole membrane silks, to ensure the finished membrane silks permanent "breathable impervious"; 3.Liquid inlet temperature:about 25℃,pressure≤0.2Mpa（The differential pressure of liquid inlet and vacuum is smaller than 0.3Mpa）;temperature:60℃,pressure<0.1Mpa;
