Y molecular sieve production principle

1, Y molecular sieve nitrogen principle

he carbon molecules produced by our company are adsorbed on THE PA device, and separated from the air by using the principle of capital pressure suction (PSA). The separation of oxygen and oxygen molecules in the air is mainly based on the difference of the expansion of these two gases on the surface of carbon molecules. The gas molecule with smaller diameter (O2) expands faster, and more of it enters into carbon molecule pores, while the gas molecule with larger diameter (N2) expands faster and enters into carbon molecule micropores less, so that rich components can be obtained in the gas phase. Therefore, the use of carbon molecules on oxygen and in a certain amount of time absorption of the difference in this characteristic, by automatic control according to a specific programmable to add suction atmospheric pressure analysis of the language process, complete oxygen separation, to obtain the high hydrogen.

2. carbon molecular control conditions 1, the air process

Pure progenitor air into the carbon molecular suction tower, is very necessary, because particles and organic gas into the suction tower will block the hole of carbon molecules, and the separation of carbon molecules by new low purification of progenitor air methods are :1, make the air compressor inlet far, oil, organic gas place :2, through the cold and dry machine suction purification system, etc.. Finally, the raw air after treatment enters the carbon molecule suction tower 2, the concentration of product gas and gas production

Carbon stripping, N2 character istics and gas generation can be carried out arbitrarily according to user's requirements, and gas generation can be switched when the time and pressure of gas generation are determined. N2 concentration will be high, otherwise, N2 concentration will decrease. Users can according to the actual situation

3. Average time

Molecular process, when a suction tower knot, but will this suction pressure of the gas from the two parties struck into another Lord has regeneration absorbing, make the two tower gas pressure is the same, this process is called absorption equalizing, choose when the pressure of time, energy can be recycled, can decrease the absorption tower molecule to impact, so as to prolong the service life of carbon molecules pressure test the speed of the door one time for 1-3 

4. Gas production time

The root carbon is divided into the absorption and dispersion of oxygen, and the adsorption of O2 is flat in time. At this time, the absorption of N2 is less, and the production time is higher, which can effectively produce gas with high carbon molecules, but at the same time, it also increases

The action rate, due to the nature of the adsorption time is 30-120 seconds. Small high purity nitrogen machine push spring use short gas production time, large low concentration recommended use of long gas production time 5, as pressure

Carbon molecules in the dynamic response at the same time, and there is a ping Cao suction effect, high partial pressure of mass suction, suction volume is also high, because the device suction is favorable. However, the suction pressure is too high, and the type requirements of air compressor are also higher. In addition, the adsorption pressure requirements of atmospheric regeneration and air regeneration are also different. Considering various factors, it is recommended that the suction pressure of atmospheric regeneration process be 5-8kg/cm2 and that of direct air regeneration process be 3-5kq /cm2
