った。In the conventional fumigating apparatus, a plurality of pressurized ventilation fans are provided on a ceiling or a wall in a closed warehouse to disperse fumigation gas. In this case, the ventilation fan is on a business trip inside the warehouse,
The cargo could be damaged by hitting a ventilation fan during cargo handling, and it was necessary to pay attention to the work. In addition, the space formed between the ventilation fans and between the ventilation fans becomes a dead space in which cargo cannot be stored, and the effective volume is reduced accordingly. Such dead space increases the dosage required to create a standard gas concentration in the warehouse. That is,
Since the gas concentration is specified at the place where the cargo is actually stored in the warehouse, in order to obtain the reference value of the gas concentration at this position, it must be determined by the warehouse volume including the above-mentioned dead space There was a disadvantage.

行なわれる。At the time of gas agitation, a chemical is introduced into the air supply chamber from the exhaust chamber during circulation air supply, and is pressurized by a blower and sent to the air supply chamber as fumigation gas. The fumigation gas is blown downward from the opening of the plate body of the air supply chamber toward the lower part of the processing chamber. At this time, since the opening area of the plate body is sufficiently smaller than the area of the inner surface of the air supply chamber, air is blown out from the entire opening at a uniform pressure. In the processing chamber, the floor surface is also made of a plate with the same structure, so that the flow of fumigation gas goes from top to bottom, so-called laminar downflow, and the fumigation gas reaches every corner of the fumigated material Processing is performed.

て吹出される。The air supply chamber 4 is communicated with the outside of the warehouse via a valve 14, and the outside air is taken in by opening the valve 14.
6. It is communicated with the exhaust chamber 8 via the blower 18. That is, the blower 18 sucks the fumigant gas 5 flowing from the processing chamber 10 to the exhaust chamber 8 through the exhaust port 6A of the lower hole plate 4 through the intake duct 20, and supplies this processing gas to the blower duct 21 and the valve 16 connected to the discharge port. To the air supply chamber 4 via the The fumigation gas is blown out from the air supply chamber 4 through the outlet 2A of the upper perforated plate 2 to the entire processing chamber 10 as a laminar downflow.
このように、くん蒸ガスはバルブ16の開動作によって
送気室４−処理室10−排気室８−送風機18を通って循環
し、処理室内を均一に通流する。As described above, the fumigation gas circulates through the air supply chamber 4, the processing chamber 10, the exhaust chamber 8, and the blower 18 by opening the valve 16, and flows uniformly through the processing chamber.

室内に向けて吹出される。Various chemicals are selected for the fumigation gas to be used depending on the fumigant to be fumigated. For example, fruits and vegetables use CH 3 Br, HCN and the like. The medicine that produces fumigant gas is introduced from the dispenser 22 into the exhaust chamber 8. The dispenser 22 is configured to suck the air in the exhaust chamber 8 through the suction pipe 22A, mix the air with the medicine, and then re-enter the air into the exhaust chamber 8 through the input pipe 22B. When the medicine is introduced from the dispenser 22 into the exhaust chamber below the floor, the medicine is sucked into the blower 18 through the duct 20 together with the exhaust air from the processing chamber 10. Then, the air is pressurized by a blower and sent to the fan room 4 through a duct 21 and a valve 16.
Since the area of the inner surface of the blower chamber 4 is sufficiently larger than the opening area of the perforated plate 2, the discharge pressure (dynamic pressure) of the blower does not act locally on the perforated plate, and the processing is uniformly performed from the outlet 2A. It is blown out toward the room.

と同じ動作を行う。As described above, the fumigation gas flows through the processing chamber 10 as a laminar flow of downflow. However, since a place where the fumigation gas is difficult to flow depending on the mounting state of the fumigated material occurs, the circulation (ventilation) of the fumigation gas is performed. ) Is usually performed several times. Reference numerals 23A and 23B denote valves provided on the suction pipe 22A and the charging pipe 22B of the administration device 22, respectively. The discharge side of the blower 18 is connected via a duct 24 to an exhaust gas treatment device (not shown) for treating used fumigation gas. The opening and closing of the valve 26 provided in the duct 24 is opposite to that of the valve 16,

理装置に送られる。The warehouse 1 is 8000 mm long, 4000 mm wide, and 3000 mm high. An upper perforated plate 2 with an aperture ratio of 20% is attached to the upper part of this warehouse.
On the floor, a grating 28 is laid on the upper surface of the lower perforated plate 6, as shown in FIG. The exhaust chamber 8 below the floor is connected to the duct of the blower 18 and is supplied with a cyanide gas (HC
N) turning at a rate of 1.8 g / m 3. Under these conditions, when the valves 14, 26 are closed, the valve 16 is opened, and the blower 18 is operated, the hydrocyanic acid gas as the fumigation gas is blown into the processing chamber at a uniform blowing pressure from the blowing port 2A on the entire upper perforated plate, and It flows in a laminar flow due to the action of the lower perforated plate constituting the floor and the grating. Therefore, the processing chamber 10 has less variation in the gas concentration distribution, and the entire chamber can be made uniform in a short time. As a result, the gas concentration at the gas concentration measurement point in the processing chamber 10 shown in FIG.
The time required for gas homogenization was about 15 minutes, which was much shorter than the time required for gas homogenization. On the other hand, when discharging gas, the valves 14, 26 are opened, the valve 16 is closed, and the blower 1
When 8 is operated, outside air is taken into the air supply chamber 4 and the outlet 2
A is blown into the processing chamber from A, and the fumigant gas filled in the chamber is pushed out by the outside air and discharged to the exhaust chamber 8 through the grating 28 and the exhaust port 6A of the lower perforated plate. The exhaust gas is sucked into the blower 18 through the duct 20 and then sent from the blower through the ducts 21 and 24 to the exhaust gas treatment device.

が一層促進される。In the present embodiment, the fumigant gas supplied to the air supply chamber 4 is blown into the room from the opening where the opening 54A of the movable plate 54 and the opening 50A of the fixed plate 50 coincide. At the same time, the movable plate reciprocates in the direction of arrow A shown in FIG. 6 by the operation of the moving devices 58 and 60, and the portion where the opening of the movable plate coincides with the opening of the fixed plate sequentially moves. As the movable plate moves, the area of the opening where both plates coincide also changes continuously, so that the amount of fumigation gas blown out from the opening at a certain position of the fixed plate also changes continuously. Therefore, in the processing chamber, a portion having a different air volume can be created locally in the arrangement direction of the air outlets, and the respiration of the fumigation gas occurs to further promote the processing of the fumigated material.
