<p>PURPOSE:To enhance the efficiency of the title apparatus and reduce the size thereof by introducing part of oxygen taken out of one adsorption tower into the other adsorption tower through an orifice placed side by side with a check valve of the other adsorption tower side. CONSTITUTION:In case magnet valve V1 is open and V3 closed, air of 2.0- 3.5kg/m<3> is supplied to adsorption tower 1 from air compressor 3 through buffer tank 4. The internal press. of tower 1 is slowly raised by the compressed air supplied, yet the internal press. of adsorption tower 2 leads to the air and slowly reduces since magnet valve V4 is open. When this state is being sustained, by opening magnet valve V6 oxygen in tower 1 is introduced into tower 2 through orifice 10 by the internal press. difference between towers 1, 2. Exhaust gas, etc. adsorbed on zeolite in tower 2 are cleaned with the oxygen introduced, thus regenerating the zeolite.</p> |
