Description of the Related Art It has been known that natural fiber, such as cotton, undergoes a change in crystal structure and fibril arrangement when treated with liquid ammonia to improve its performance such as flexibility, shrinkage resistance, wrinkle resistance and strength improvement. . That is, in order to subject the natural fiber to shrink-proofing, wrinkle-proofing and the like, usually, the fiber is immersed in liquid ammonia in the processing chamber and then the ammonia gas is evaporated by heating. However, this fiber processing chamber is kept at a negative pressure slightly lower than the atmospheric pressure to prevent leakage of ammonia gas.

(1) Since combustible, toxic and corrosive ammonia gas is compressed to a high pressure of 10 atm or more, there is a strong risk that the gas may leak out of the device. (2) In order to withstand the contact of high-pressure ammonia gas, the recovery device is strongly restricted in material and structure, and the manufacturing cost becomes high. (3) While the ammonia gas is compressed to a high pressure by the compressor 3, the processing chamber 1 is maintained at a negative pressure, so that the pressure control of the processing chamber 1 is not easy. An object of the present invention is to safely and inexpensively recover ammonia gas and simply control the pressure of a processing chamber.

That is, according to the present invention, in the ammonia gas recovery liquefaction apparatus having the basic structure, the pressure treatment device 3 is composed of a blower, the condenser 4 is interlocked with the refrigerator 5, and the ammonia gas is refrigerated in the condenser 4. 5, the refrigerant supplied from 5 heat-exchangeable, the ammonia gas passing through the ammonia gas recovery passage 2 is pressurized to less than 2 atm by the blower 3, and is condensed in the condenser 4 by the cold heat of the refrigerant from the refrigerator 5. It is characterized in that it is configured to. The processing chamber 1 refers to a processing chamber for shrink-proofing and wrinkle-proofing the fibers.

の圧力差が小さい。The ammonia gas recovered from the processing chamber 1 need only be pressurized to less than 2 atm by the blower 3, so it is not necessary to compress it to 10 atm or more with a compressor as in the conventional case, and ammonia gas leaks out of the equipment. There is no danger of putting it out. Further, since the ammonia gas is pressurized at a low pressure, the requirement for durability of the ammonia gas recovery device is relaxed to a greater extent than before, and the structure of the ammonia gas recovery device is simplified.
Moreover, since the ammonia gas pressurized at a low pressure is sent to the condenser 4, only by exchanging heat with the refrigerant from the refrigerator 5, low-pressure and low-temperature liquid ammonia can be easily obtained. For this reason,
It is not necessary to condense the ammonia gas to a high pressure / normal temperature in the condenser 4 and then to perform self-cooling by pressure reduction / expansion by the throttle valve 50 as in the conventional technique. On the other hand, since the blower 3 pressurizes the ammonia gas at a low pressure, the pressure difference between the processing chamber 1 and the pressurizing section is small, unlike the conventional technique using a compressor.

(2) Since the requirement of durability of the ammonia gas recovery device can be relaxed by the above (1), the manufacturing cost of the ammonia gas recovery device can be reduced. Further, in the present invention, unlike the conventional case, it is not necessary to perform the two-stage treatment of condensation and decompression expansion, and it is sufficient to exchange heat of ammonia gas with the refrigerant of the refrigerator, so that low-pressure / low-temperature liquid ammonia can be promptly recovered. . (3) Since the set pressure difference in the apparatus is reduced by the above (1), the pressure in the processing chamber can be easily controlled.

While being dipped in the container to be subjected to shrinkage-proof and wrinkle-proofing treatment, most of the liquid ammonia attached to the natural fiber A is vaporized and evaporated by the heater 10.

を導出し、排気路１８に除害装置１９を介装する。The buffer chamber 13 is a gas tank having a relatively small capacity. The blower 3 is driven by the electric motor 15, sucks the ammonia gas evaporated in the processing chamber 1 through the ammonia gas recovery passage 2, and then pressurizes it at a low pressure. Therefore, the inside of the processing chamber 1 surrounded by the casing 12 is maintained at a negative pressure slightly lower than the atmospheric pressure (specifically, a negative pressure of several mm to several tens of mm of water column). The negative pressure control can be relatively easily performed by controlling the inverter of the electric motor 15 that drives the blower 3. The cooler 14 cools the ammonia gas pressurized to a low pressure by the blower 3. The condenser 4 is interlocked with the Freon refrigerator 5 to cool and condense the ammonia gas having a lowered temperature. For this reason, in the condenser 4, a circulation pipe 16 for the refrigerant led from the Freon refrigerator 5 is arranged in a protruding manner. Further, a gas storage chamber 17 is provided so as to project from the upper wall of the condenser 4, and the gas storage chamber 17 is connected to the exhaust passage 18 through the gas storage chamber 17.
And the abatement device 19 is provided in the exhaust passage 18.
