How long is the activated carbon of nitrogen production be replaced
Special activated carbon for PSA nitrogen machine, choose excellent fine coal as raw material, through crushing, grinding, mixing, molding, carbonation and activation, etc, with high mechanical strength, neat shape, uniform particle size, large surface area and less surface dust, and large hole, hole, micro-hole, appropriate quantity, fast adsorption speed and bed resistance is small.It is suitable for direct deoxygenation of nitrogen, argon, helium, carbon monoxide, carbon dioxide and other inert gases. It is widely used in nitrogen purification equipment and air separation nitrogen production equipment, and it is also especially suitable for variable pressure adsorption nitrogen purification and oil absorption.
Maintenance advice for the nitrogen production machine
1）Timed drain is added to the air tank to reduce the load pressure.
2）The normal use of the equipment should pay attention to check whether each timing drain is normal drainage, whether the air pressure meets the above 0.6Mpa, touch the import and export comparison of the cold dryer, whether there is refrigeration effect.Check that the purity of the nitrogen gas is stable。
3）The air filter must be replaced at every 4,000 hours.
4）How long is the activated carbon replaced?Activated carbon filter can effectively filter oil, can prolong the service life of high-quality carbon molecule sieve, activated carbon needs to be replaced in 3000 hours or 4 months.
5）The pneumatic valve and solenoid valve of the nitrogen production machine are recommended for each model of action components to prevent future problems.
Characteristics of the activated carbon in the nitrogen generator
Due to the use of high quality wood chips, coconut shell as raw material, the columnar activated carbon made than the traditional coal columnar carbon low ash content, less impurities, gas adsorption value, CTC advantage.
Coal columnar activated carbon has the advantages of developed void structure, large specific area, strong adsorption capacity, high mechanical strength, small bed resistance, good chemical stability, easy regeneration, durability and so on.
The product aperture distribution is reasonable, reaching the maximum adsorption and desorption, thus greatly improving the service life of the product (average 2-3 years), which is 1.4 times that of ordinary coal carbon.
Activated carbon applicability：
1、Gas phase adsorption；
2、Organic solvent recovery (benzene gas toluene, acetone recovery in acetate fiber industry)；
3、Remove impurities and harmful gases, waste gas recovery；
4、Excessive gasoline recovery from oil refineries, gas stations and oil depots；
5、Preparation of trichloroethylene by catalytic mean tetracloroethane and deHCl of activated carbon
