Description

Pollutants for gas in the gas remove device
The present invention relates to from gas, remove the device of removing of pollutants for gas.
In the prior art, the instrumentation machine of gaseous matter in the divided gas flow has the separator that adopts diffusion scrubbing (ス Network ラ バ) method.
Fig. 7 represents this separator.In this device, in the cylindrical shell 1, disposing by porous polyfluortetraethylefilm (テ Off ロ Application) PPTFE) pipe 2 that constitutes of hydrophobic film.
Make liquid E circulation between housing 1 and pipe 2, contain gas K circulation in pipe 2 of gaseousness material and particulate matter, like this, the gaseousness material among the gas K is shifted to liquid E side, and the gaseousness material separates from gas K.
That is, as shown in Figure 8, form on the hydrophobic film of pipe 2, form small hole 2a, because the particulate matter L among the gas K is different with the diffusion coefficient of gaseousness material G, only gaseousness material G shifts to liquid E side by micro hole 2a.
But, in this existing separator,,,, be not suitable for general air-conditioning equipment in cylindrical tube 2 though in the instrumentation machine of divided gas flow material G, can use so the disposal ability of gas K is low because gas K is circulated.
That is, in the existing separator, if it is big to manage 2 internal diameter, then the separative efficiency of gaseousness material G is low, must reduce by managing the wind speed of 2 gas K.
For example, internal diameter is that if wind speed is not reduced to 13cm/s, then separative efficiency is no more than 90% in the pipe 2 of 9mm, if wind speed is 26cm/s, then separative efficiency is reduced to 80%.
In the pipe 2 of internal diameter 4mm, when wind speed was 26cm/s, separative efficiency was 96%; When wind speed was 66cm/s, separative efficiency was 93%; When wind speed was 130cm/s, separative efficiency was 82%.Compare with the device of 9mm, can select about 5 times wind speed.
In addition, in the existing separator, from the Gorley-Kennedy empirical formula as can be known,, then be not easy to guarantee the separative efficiency more than 95% if manage 2 the unlikely 500m of length when above.
At this moment air quantity is 1000cc/min, and wind speed is 130cm/s, and it is too small to handle air quantity, is applicable to general aircondition etc.
Handle air quantity even sacrificial separation efficient improves, air quantity also can only reach 2000cc/min.
Therefore, in the existing separator, because the internal diameter of pipe 2 is little, the pressure loss is big, so the power cost height.
In addition, pipe 2 wall thickness is very thin, for example be 0.5mm, so when the flow velocity of gas K was accelerated, stress acted on the junction surface of pipe 2 and housing 1, may produce and break or the disengagement at junction surface.
In addition, used many pipes at 2 o'clock, for example as shown in Figure 9, pipe 2 is configured to clathrate, from the making aspect, in the aperture opening ratio less than 28% of the pipe 2 of cross-section face, compares with the ventilating part (pipe arrangement, pipeline) of gas K, needs the area of section about 3 times.
