zeolite molecular sieves the gap with foreign countries is growing

zeolite molecular sieves the gap with foreign countries is growing. 1970s was the heyday of PSA oxygen air separation technology development, there are more than a dozen units have carried out  synthetic zeolite powder supplier experimental research PSA oxygen technology, the establishment of a number of sets of industrial test equipment. During this period the development of PSA oxygen equipment common in the following areas:
they use a higher than atmospheric grace molecular sieves  pressure adsorption, desorption atmospheric processes, adsorption tower has two to four;
 before the air enters the adsorber, after dehydration pretreatment;
Poor (3) equipment reliability, not continuous and stable operation, resulting in most of the equipment scrapped;
 technical, economic indicators lag behind.
1980s, the original PSA oxygen equipment in research and development unit of development projects have been suspended, the development of technology, PSA oxygen into the trough again.

activated molecular sieves air filter contaminated air through

activated molecular sieves Micro fan inside the machine (also known as ventilator) indoor air circulation, molecular sieves 13x air filter contaminated air through the machine inside (two filters) will remove a variety of contaminants or adsorption, and then after installed in the outlet of the negative ion generator 4a zeolite molecular sieves (when working in high-pressure ion generator to generate negative high voltage direct current), will continue to air ionization, a large amount of negative ions, being sent out micro fans, form negative ions flow, to clean and purify the air of purpose, thus provide people with a similar nature in the fresh air "micro climate."

The principle is the use of industrial oxygen air separation technology

The principle is the use of industrial oxygen air separation technology,first, a high density compressed air to the condensation point of the air in the re-use of the components is different so air separate unit molecular sieve  that in the gas and liquid from a certain temperature,activated molecular sieves and further distillation derived; home oxygen works: the use of molecular sieve physical adsorption and desorption techniques. molecular sieves 4a  Filling the molecular sieve oxygen generator can be adsorbed nitrogen pressurized air, the remaining oxygen is not absorbed is collected, after purification was turned into high-purity oxygen.
