What Is The Inspiration For The Construction And Manufacturing Process Of Ground Screw Piles?

The spiral ground pile can adsorb oxygen and nitrogen in the air together, and its adsorption capacity also increases with the increase of pressure, but there is no significant difference in the equilibrium adsorption capacity of oxygen and nitrogen under the same pressure. Therefore, it is difficult to achieve effective separation of oxygen and nitrogen only by changing the pressure. If the speed of adsorption is further considered, the adsorption characteristics of oxygen and nitrogen can be usefully distinguished. The molecular diameter of oxygen is smaller than that of nitrogen, so the dispersion speed is hundreds of times faster than that of nitrogen, so the carbon molecular sieve absorbs oxygen very quickly, and the adsorption reaches more than 90% in about 1 minute; while the adsorption amount of nitrogen is only about 5% at this moment, So at this moment, what is adsorbed is mostly oxygen, and the rest is mostly nitrogen. In this way, if the adsorption time is controlled within the limit, oxygen and nitrogen can be separated, that is to say, adsorption and desorption are accomplished by pressure difference, when the pressure increases, the spiral pile absorbs and when the pressure decreases, it desorbs . The difference between oxygen and nitrogen depends on the speed difference between the two being adsorbed. By controlling the adsorption time, the time is controlled to be very short. The oxygen has been fully adsorbed, and the adsorption process is stopped before the nitrogen can be adsorbed in the future. Therefore, the pressure swing adsorption nitrogen generation must have a pressure change, and the screw ground pile must also control the time within 1 minute.
