できる。[0008] Ammonia gas generated in the processing chamber is converted into liquid ammonia in a liquefier and returned to the storage tank. Therefore, the amount of wasted ammonia is significantly reduced. Moreover, the pressure inside the processing chamber can be controlled by adjusting the amount of ammonia gas introduced into the liquefaction device from the processing chamber.

などを阻止している。A processing chamber 14 and a volatilization chamber 16 are provided by partitioning a chamber 10 made of a corrosion-resistant material such as stainless steel with a partition wall 12 . A cloth 18 as a workpiece is introduced into the processing chamber 14 through an inlet 20, guided by a guide roller (not shown), and immersed in liquid ammonia in a storage tank 22. The cloth 18 pulled up from the storage tank 22 is attached to and sent to a drum 23 heated with steam, whereby most of the ammonia attached to the cloth 18 is gasified. Then, it is further guided by a guide roller (not shown) and introduced into the volatilization chamber 16 from the transfer port 24. A steamer 28 provided in this volatilization chamber 16 applies high temperature (for example, 98° C.) water vapor to the cloth 18, and liquid ammonia remaining on the cloth 18 is gasified. The cloth 18 that has been sufficiently deammoniated is taken out from the outlet 30 and becomes a treated product (which has a unique silk-like appearance and feel when further processed). Note that the introduction port 20
Appropriate sealing mechanisms (not shown) are provided at the transfer port 24 and the take-out port 30 to prevent outflow of ammonia gas and inflow of air.

５７により調整される。The ammonia gas generated in the processing chamber 14 is
It passes through a pipe 32 and a damper 34 and is compressed by a compressor (in this embodiment, a positive displacement compressor) 36. Note that part of the gas discharged from the compressor 36 (for example, 10 to 20%)
) is returned to the upstream side of the compressor 36 via a pipe 40 with a valve 38. The remainder of the gas discharged from the compressor 36 is sent from a pipe 42 to a condenser 44, where it is liquefied. Liquid ammonia is sent from this condenser 44 to an ammonia tank 46 and then returned to storage tank 22 via filter 48, cooler 50, and piping 52. (In this embodiment, these tank 46, filter 48, cooler 5
0 and piping 52 constitute a return line. ) Note that the processing chamber 14 is provided with a pressure sensor 54, and the opening degree of the valve 38 is adjusted by the controller 56 so that the pressure detected by the sensor 54 is constant. Since the pressure regulating mechanism is provided in this way, the pressure inside the processing chamber 14 can be adjusted to a pressure that is very slightly lower than atmospheric pressure (for example, -10 mmAq).
), thereby preventing air from entering the processing chamber 14 and ammonia gas from leaking into the atmosphere from the processing chamber 14. Control of this pressure regulating mechanism is performed as follows. For example, when the feeding speed of the cloth 18 becomes faster or the width of the cloth 18 becomes wider and the amount of ammonia gas generated increases, and the pressure inside the processing chamber 14 increases from, for example, -10 mmAq to -5 mmAq, the pressure sensor 54 This is detected, the opening degree of the valve 38 is reduced, and an amount commensurate with the increased amount of gas is drawn out from the processing chamber 14 into the piping 32 and sent to the piping 42 line to be liquefied.
The pressure inside the chamber is adjusted so that it is always maintained at -10 mmAq. Note that the opening degree of the damper 34 is adjusted by a manual controller 57.

れる。The ammonia gas removed from the cloth 18 in the volatilization chamber 16 is sent from a pipe 60 to a scrubber 62 where it is absorbed. The unabsorbed gas components are sent from the piping 64 to the mist separator 66, where they are separated into mist.
It is sent to a final scrubber 74 via a pipe 68, a blower (roots blower in this embodiment) 70, and a pipe 72. The water discharged from the scrubber 74 is sent to wastewater treatment equipment. In addition,
Discharge water (ammonia water) from the scrubber 62 and the mist separator 66 is also sent to the wastewater treatment facility via pipes 76 and 78.

A pressure sensor 84 is provided in the volatilization chamber 16, and the opening degree of the valve 82 is controlled by a controller 86 so that the pressure detected by the sensor 84 becomes a predetermined pressure. As a result, the pressure inside the volatilization chamber 16 is reduced to -5 m, for example.
By creating a very slight reduced pressure of about mAq, it is possible to prevent ammonia gas from leaking into the atmosphere from the volatilization chamber 16.

る。[0016] The amount of ammonia gas generated within the processing chamber 14 rapidly increases, and the compressor 36 and condenser 4
In case the increase in the liquefaction capacity of the liquefaction apparatus consisting of 4 cannot keep up with this increase, the inside of the processing chamber 14 and the pipe 60 can communicate with each other through a pipe 91 equipped with a shutoff valve 89. This shutoff valve 89 is normally fully closed, and the processing chamber 14 and the pipe 60 are not communicated with each other at all. As mentioned above, if the amount of ammonia gas generated in the processing chamber 14 suddenly increases for some reason, such as when the feed speed of the cloth 18 is suddenly increased, and the liquefaction capacity cannot keep up with this (for example, when the processing chamber Pressure inside 14 is +30mmAq
or more), this shut-off valve 89
will be released. As a result, an excessive amount of ammonia gas is absorbed by the scrubber 62, and dissipation into the atmosphere is reliably prevented. Further, the pipe 32 and the pipe 60 can communicate with each other through a pipe 90 equipped with a shutoff valve 88. This valve 88 is normally fully closed, but if the compressor 36 abnormally stops for some reason, it is automatically opened so that the ammonia gas generated in the processing chamber 14 is absorbed by the scrubber 62. ing.

When the pressure inside the machining chamber 14 suddenly decreases (for example, when it drops to -20 mmAq or less), the valve 92 is opened and the gas is replenished into the machining chamber 14 using the replenishing device 96 to reduce the pressure inside the machining chamber 14. recovery and ensure that atmospheric air is prevented from entering.
