摘要： PURPOSE: To smooth the flow down of a liquid, lower the pressure loss of a packed tower, widen the range of driving operation by installed a second packing material easy to be manufactured at a low cost in the lowest end part of a first packing material and, furthermore, to miniaturize an air separating apparatus and lower the cost of the apparatus by utilizing the packed tower as the air separating apparatus. CONSTITUTION: A gas 11 passes an inlet pipeline 13 of a packed tower 10, enters the bottom of the tower, and rises toward the top of the tower. Meanwhile, being brought into gas-liquid contact with the gas 11 through a first packing material 40, a liquid 12 from the top of the tower passes through a second packing material 41 which is set in the lower-most part and whose flow line is set to be parallel to the axis of the tower, and flows down smoothly.

摘要： PURPOSE: To reduce pressure loss and to widen an operation range by smoothing the flowing-down of a liquid from the corrugated groove of a packing material. CONSTITUTION: This packed column is constituted so as to have such a structure that the lower end 11 of the packing material at the lowerst part of a packed bed constituted at every block is arranged at the position being in contact with the surface 21 of the liquid present in the lower part of the column or at least immersed in the liquid. By this constitution, since the liquid continuously flows out of the lower end part of the packing material at the lowermost part of the packed bed, the packed column reduced in pressure loss and wide in an operation range can be provided.

摘要： PURPOSE:To obtain LN2 at a cost approximately the same with the that market price thereof at an arbitrary time by combining a pressure swinging absorption tower(PSA) with a He refrigerator, the volume thereof being small and the whole installation being compact. CONSTITUTION:After dusts are removed from material air 1 by a filter 2, the air is pressurized to a predetermined pressure (4-5kg/cm G) by an oil-free baby compressor 3, and dry nitrogen gas 6(-99.99% N2) is obtained through an absorption tower 4 packed with CO2, H2O-removing absorber and an absorption tower 5 packed with oxygen absorber. The gas 6 is reduced under pressure to the atmospheric pressure by a pressure reduction valve 7, then supplied to a Dewar bin 8, in which it is brought in contact with the tip end of the cylinder 10 of a He refrigerator 9 to be liquefied by cooling, and stored in the bin 8. Liquid nitrogen 13 stored in the bin 8 is supplied through a supply line 15 having a vacuum double structure by opening an evaporation valve 15 as required.

摘要： PURPOSE:To obtain a dry flower in a short time without impairing the original shape and color, by placing a natural flower in a container constituted of a heat insulating material, etc., embedding the natural flower in a dehumidified and heated powdery or granular absorbent material and preventing water from entering the interior of the container. CONSTITUTION:A natural flower is placed in a container constituted of a heat insulating material, etc., and humidifying treatment, as necessary, is added thereto. The resultant natural flower is then embedded in a dehumidified and heated powdery or granular absorbent material to prevent water from entering the interior of the container. Water of the natural flower is evaporated and removed to afford the aimed dry flower. The absorbent material may be a mixture of a thermal energy storing material with moisture absorbing material and silica gel, ceramic, etc., are used. The absorbent material may be partially constituted of a magnetic substance or electric conductor. A wire net is preferably provided in the upper part of the absorbent material and only the absorbent material is released from the container in turning over the container. The above- mentioned method has advantages in that the container can be supplied at a low cost and the absorbent material can be reutilized.

摘要： PURPOSE: To install cooling means separately from a compressor, arrange means capable of discharging heat out of a room and prevent a dwelling comfortable feeling from being damaged by a method wherein there are provided the compressor installed in the room and cooling means for cooling gas compressed by this compressor. CONSTITUTION: Gas compressed by a compressor 10 generates heat to have a high temperature. This compressed gas of high temperature is cooled by an air-cooled cooling device 30. At this time, heat removed from the compressed gas through a cooling device 19 and subsequently removed from lubricant oil 13 through a cooling device 18 by the cooling device 30 spaced apart from the compressor 10 and installed near a window 2 via pipes 61, 62 is cooled by surrounding atmosphere under a rotation of a fan 34 and then warm air is discharged out of a room. Due to this fact, it is possible to cool the compressed gas without damaging a dwelling comfortable property in a room.

摘要： PURPOSE:To perform continuous polycondensation of the titled resin with a simple inexpensive apparatus, by integrating an impeller, a discharger and a feeder in the body of a vessel into a whole. CONSTITUTION:A highly viscous liquid to be treated (e.g., polyethylene terephthalate) is fed through an entrance nozzle 8 to the body 1 of a vessel, mixed by agitation with an impeller 3, polycondensed and allowed to reach a weir 5 at the extremity of a mixing chamber 12. The liquid goes over a gangway 14 on the top of the weir 5 and flows into a gear chamber 13, sent downwardly by the rotation of gears 4a and 4b and discharged at a constant rate from an exit nozzle 9 by transmitting a rotation torque from a rotary axis 2a on the driving side to a rotary axis 2 on the driven side. Volatile matte formed in the body 1 is discharged from an exit nozzle 10.

摘要： PURPOSE:To enhance gas-liquid contact efficiency by a method wherein a shelf step and a perforated plate in a gas-liquid contact tower are divided into two parts and a liquid on the perforated plate is flowed into a liquid flow passage without being short-passed into a flooding pipe to make a liquid flow amount on the perforated plate uniform. CONSTITUTION:A liquid lowered from flooding pipes 4a, 4b in a gas-liquid contact tower 1 is passed over inlet dams 5a, 5b and flowed into a liquid flow passage 3 as a two-directed stream from both ends of perforated plates 7a, 7b. In this case, because side walls 7a, 7b of the flooding pipes are extended upwardly, the liquid on the perforated plates 6a, 6b is flowed into the liquid flow passage without being short-passed to the flooding pipes 4a, 4b and advanced to both sides of the liquid flow passage 3. Subsequntly, said liquid is flowed into the flooding pipes 4a, 4b and passed through a gap with a lower shelf step 2 and, further, passed over inlet dams 5a, 5b to be reached on the perforated plates 6a, 6b. Thereinafter, on each shelf step 2, the above desicribed flow is repeated. A gas raising in the tower passes the perforated plates 6a, 6b to carry out gas-liquid contact with the liquid distributed on the perforated plates 6a, 6b.
