Release to the target room to decontaminate the room.

JP-A-7-227418

  By the way, when the decontamination target chamber is decontaminated by the indoor decontamination apparatus, the decontamination gas is discharged from an appropriate place in the room so that the decontamination gas can be smoothly distributed to every corner of the decontamination target chamber. It is desirable. However, in the conventional indoor decontamination apparatus, since the housing containing the decontamination gas generator is large, the place where it can be installed in the decontamination target room is limited, and the decontamination gas is appropriately used. There was a problem that it could not be released from the place, and the decontamination in the room was insufficient, or it took a long time for decontamination.

  In addition, when decontaminating a complex-shaped decontamination target chamber, it is difficult to spread the decontamination gas to every corner by simply discharging it from one location. It is desirable to release dye gas. In such a case, in the conventional indoor decontamination apparatus, a plurality of casings equipped with the decontamination gas generation apparatus are installed in the room, but there are as many decontamination gas generation apparatuses as there are decontamination gas discharge locations. It was expensive because it was necessary.

  An object of the present invention is to provide an indoor decontamination apparatus capable of efficiently decontaminating a decontamination target room.

  The present invention comprises a decontamination gas generating device that generates a decontamination gas, and is installed in a decontamination target room and in the decontamination target room apart from the main unit, and decontamination A slave unit connected to the master unit via a gas supply pipe and discharging decontamination gas supplied from the master unit via the pipe from the decontamination gas discharge port to the decontamination target chamber; This is an indoor decontamination device.

  In such an indoor decontamination apparatus, the decontamination gas generated from the decontamination gas generator of the master unit is supplied to the slave unit via the pipe and discharged into the room from the decontamination gas discharge port of the slave unit. The Rukoto. The slave unit can be made smaller than the master unit by the amount not equipped with the decontamination gas generator, and the degree of freedom of installation in the decontamination target room is high. For this reason, in the indoor decontamination apparatus of this invention, decontamination gas can be discharge | released from the appropriate place of a decontamination object room | chamber by discharging | emitting decontamination gas from this subunit | mobile_unit.

  Moreover, in the indoor decontamination apparatus of the present invention, a configuration including a plurality of slave units or a configuration where the master unit includes a decontamination gas discharge port for discharging a decontamination gas into the decontamination target chamber is proposed. According to such a configuration, it becomes possible to release decontamination gas from a larger number of locations with respect to the number of decontamination gas generators, and the cost of the indoor decontamination device required for decontamination than the conventional configuration can be reduced. Can be reduced.

  The cordless handset is attached to the upper part of the casing, the pipe for supplying the decontamination gas being connected, and a casing for receiving the decontamination gas therein and a decontamination gas discharge port opening obliquely upward. A structure is proposed in which the rotary emitter communicates with the casing through a vertical communication pipe and is driven to rotate horizontally around the communication pipe. .

  In such a configuration, the decontamination gas supplied from the main unit to the sub unit can be discharged in a dispersed manner around the sub unit from the horizontally rotating rotary emitter, and the decontamination gas is discharged into the decontamination target chamber. Can be dispersed efficiently.

  Further, in the above configuration, the rotary emitter includes a plurality of slit-like decontamination gas discharge ports, and each decontamination gas discharge port has an adjustment plate that partially closes the decontamination gas discharge port. A configuration is proposed in which the height position for closing the decontamination gas discharge port can be adjusted by sliding the adjustment plate along the longitudinal direction of each decontamination gas discharge port. The

  In such a configuration, the decontamination gas can be efficiently dispersed in the decontamination target chamber by selecting the discharge height of the decontamination gas according to the shape of the decontamination target chamber. In addition, by adjusting the gas discharge height at each decontamination gas discharge port to be different from each other, decontamination gas is released from each decontamination gas discharge port of the rotary emitter toward different locations. Thus, the decontamination gas can be more efficiently dispersed.

  In the present invention, it is proposed that the decontamination gas is hydrogen peroxide gas, and the decontamination gas supply pipe includes a heating device for heating the inside of the pipe. Hydrogen peroxide gas is easy to condense, but according to such a configuration, it becomes possible to supply the hydrogen peroxide gas generated from the decontamination gas generator to the slave unit without condensing it in the pipe.

  Further, in the present invention, at least one of the slave units is a porous member that reflects a part of the decontamination gas emitted from the decontamination gas discharge port in a predetermined direction to the other direction at the upper part of the housing. A configuration including a reflective plate is proposed. In such a configuration, a part of the decontamination gas emitted from the decontamination gas discharge port toward the reflecting plate is reflected by the reflecting plate and emitted in the other direction, and the remaining part is It passes through the holes of the reflector and is emitted to the back side of the reflector. Therefore, if such a reflector is used, the amount of decontamination gas emitted from the rotary emitter can be changed according to the direction. For this reason, it is possible to disperse the decontamination gas evenly around the slave unit by appropriately arranging the reflecting plate in accordance with the space shape around the slave unit.

  Further, in the present invention, a configuration is proposed in which the parent device and the child device are provided with moving casters. According to such a configuration, the master unit and the slave unit can be easily installed at appropriate locations in the decontamination target room.

  In the present invention, it is also proposed that the master unit has a decontamination gas discharge port for discharging decontamination gas into the decontamination target chamber. Further, in such a configuration, the base unit has a housing with a built-in decontamination gas generator and a decontamination gas discharge port that opens obliquely upward, and is attached to the top of the housing. It is proposed that the rotary emitter includes a rotary emitter, and the rotary emitter communicates with the casing through a vertical communication pipe and is driven to rotate horizontally around the communication pipe.

  In addition, the indoor decontamination apparatus of the present invention preferably includes a decontamination gas decomposition apparatus that decomposes the decontamination gas released into the decontamination target chamber. Such a decontamination gas dispersing apparatus can be disposed in the main unit or the sub unit, or can be disposed in a separate body.

  As described above, the indoor decontamination apparatus of the present invention releases decontamination gas from a slave unit that does not include a decontamination gas generator, thereby decontaminating an existing indoor decontamination apparatus from a narrow place where it is difficult to install. Since the gas can be released, the decontamination gas can be efficiently distributed to every corner of the decontamination target chamber. Moreover, since the decontamination gas discharge | release location can be increased compared with the number of decontamination gas generators, the cost of the whole apparatus can be held down. Moreover, since the installation mode of the main unit and the sub unit can be flexibly changed in accordance with the shape of the decontamination target chamber, there is an advantage that various decontamination target chambers can be appropriately decontaminated.

  Embodiments of the present invention are described according to the following examples.

  The indoor decontamination apparatus of the present embodiment uses hydrogen peroxide gas as the decontamination gas. As shown in FIGS. 1 and 2, the indoor decontamination apparatus 1 includes a master unit 2 including a decontamination gas generation apparatus that generates hydrogen peroxide gas, and a decontamination gas supply pipe 4.

The master unit 2 is installed in the central small room C1, and the slave unit 3 is installed in the peripheral small rooms C2 and C3, respectively. The master unit 2 and the slave unit 3 are transported to the small chambers C1 to C3 of the decontamination target chamber C by the casters 10 at the bottom, and are connected to each other by the pipe 4 for supplying the decontamination gas. In such an installation example, the decontamination target room C has a relatively complicated shape divided into three small rooms C1 to C3, but the main unit 2 and the sub unit 3 are connected to the small rooms C1 to C3. Since the hydrogen peroxide gas is released from each of the small rooms C1 to C3, the hydrogen peroxide gas can be distributed to every corner of each of the small rooms C1 to C3. In addition, the installation position of the main | base station 2 and the subunit | mobile_unit 3 is suitably changed with the magnitude | size and shape of the chamber C for decontamination, and is not limited to this installation example. Moreover, the indoor decontamination apparatus 1 of the present embodiment only needs to include at least one master unit 2 and one slave unit 3, and the number of installed units is changed according to the size and shape of the decontamination target chamber C. it can.

  Moreover, the indoor decontamination apparatus 1 of the present embodiment includes a decomposition dedicated machine 8 for decomposing hydrogen peroxide gas in addition to the parent machine 2 and the child machine 3. The dedicated decomposing machine 8 includes an existing decontamination gas decomposing apparatus (not shown) composed of a blower fan, a catalyst, and the like, and decomposes hydrogen peroxide gas filled in the room to make it nontoxic. Note that the decontamination gas decomposition apparatus can be disposed in the master unit 2 or the slave unit 3 without being disposed in the dedicated decomposition unit 8.

  The indoor decontamination apparatus 1 according to the present embodiment performs the decontamination process of the decontamination target room by automatic operation by the control device 27 (see FIG. 9) disposed in the master unit 2. Specifically, at the start of the decontamination process, the master unit 2 operates the decontamination gas generator 31 (see FIG. 9) to supply hydrogen peroxide to each slave unit 3 via the decontamination gas supply pipe 4. In addition to supplying gas, power is supplied to each slave unit 3 through an electric cable (not shown) to rotate each rotary emitter 5 so that hydrogen peroxide gas is dispersed around the slave unit 3. discharge. The base unit 2 also supplies hydrogen peroxide gas to its own rotary emitter 5 and also drives the rotary emitter 5 to rotate to release hydrogen peroxide gas in a dispersed manner around itself. To do. Thereafter, when a preprogrammed decontamination time elapses, the master unit 2 stops the rotation of the decontamination gas generator and each rotary emitter 5. Next, the master unit 2 supplies power to the dedicated decomposition machine 8 via an electric cable (not shown) to operate the decontamination gas decomposition apparatus, and when a preprogrammed hydrogen peroxide gas decomposition processing time has elapsed, The operation of the decontamination gas decomposing apparatus 8 is stopped, and a series of decontamination processes is completed.

  Below, the structure which concerns on the principal part of this invention is demonstrated.

  As shown in FIGS. 1, 2, and 4, the slave unit 3 includes a stand 11 with casters 10, and a gas distribution casing 12 disposed on the top of the stand 11. The outer shape of the housing 12 has a rectangular parallelepiped shape, and a connection port 13 for connecting the gas supply pipe 4 is formed on each side surface thereof. Further, the rotary emitter 5 is attached to the upper surface of the housing 12 so as to be horizontally rotatable, and a motor 14 that rotationally drives the rotary emitter 5 is fixed to the stand 11 below the housing 12.

  As shown in FIGS. 5 and 6, the rotary emitter 5 includes a hollow metal casing 20 having a substantially chevron shape in front and a vertical communication pipe 21 attached to the bottom of the casing 20. It becomes. The decontamination gas discharge ports 6 and 6 are formed one by one on the inclined surfaces at the upper part on both sides of the housing part 20. Each decontamination gas discharge port 6, 6 has a slit shape from the upper center to the lower periphery. Each decontamination gas discharge port 6 is provided with an adjusting plate 22 that partially closes the discharge port 6. The adjustment plate 22 is provided with a groove 24 fitted to the side edge of the decontamination gas discharge port 6 on its side periphery, and is slidably assembled along the longitudinal direction of the decontamination gas discharge port 6. According to this configuration, the decontamination gas is discharged from the decontamination gas discharge port 6 by sliding the adjustment plate 22 and adjusting the height position where the adjustment plate 22 closes the decontamination gas discharge port 6. The height position to be set can be set.

  As shown in FIG. 4, the rotary emitter 5 is configured such that the communication pipe 21 is tightly fitted into a circular opening 15 formed in the upper part of the housing 12, so that the inside of the housing section 20 is connected via the communication pipe 21. And the inside of the housing 12 communicate with each other. In such a configuration, the hydrogen peroxide gas supplied to the housing 12 via the pipe 4 flows into the housing portion 20 via the communication pipe 21, and obliquely upward from the decontamination gas discharge port 6. Will be released.

  Further, the rotary emitter 5 is held so as to be horizontally rotatable around the communication pipe 21 with respect to the casing 12, and is driven to rotate by the motor 14, whereby the hydrogen peroxide gas emission direction is set to a horizontal plane. And hydrogen peroxide gas is dispersed around. The motor 14 has its main body fixed to the stand 11. The rotation shaft 16 of the motor 14 extends directly upward from the main body portion, passes through the center of the housing 12 and the communication pipe 21, and the upper end thereof is fixed to the upper part of the rotary emitter 5. The rotary emitter 5 is driven to rotate horizontally around the communication pipe 21.

  Moreover, the subunit | mobile_unit 3 is provided with the reflection plate 23 which can be attached or detached. The reflection plate 23 is made of a curved porous metal plate, and as shown in FIGS. 7 and 8, the lower end is fixed to the upper surface of the housing 12 so as to be detachable so as to cover one side surface of the rotary emitter 5. Is done. In this configuration, part of the hydrogen peroxide gas released from the rotary emitter 5 to the reflecting plate 23 is reflected by the reflecting plate 23 and flows in the other direction, and the remaining part is reflected. It passes through the hole of the plate 23 and passes to the back side of the reflecting plate 23. As described above, when the reflecting plate 23 is mounted, the amount of hydrogen peroxide gas released can be changed according to the direction of emission in accordance with the shape of the space around the aircraft. Specifically, when the wall surface is located at the W portion in FIGS. 7 and 8, when the peroxide water gas is uniformly discharged around the handset 3, the wall surface side where the space is limited is from the other direction. However, the gas concentration around the handset 3 becomes non-uniform and the degree of decontamination varies greatly. However, as shown in FIGS. 5, a part of the hydrogen peroxide gas released toward the wall surface W can be reflected in the other direction by the reflecting plate 23, thereby suppressing variations in gas concentration. It becomes.

  As shown in FIG. 9, the master unit 2 includes a metal housing 30 that houses the decontamination gas generator 31, the control device 29, and the like, and is provided by a caster 10 attached to the bottom of the housing 30. It is movable.

  The decontamination gas generator 31 includes a tank 35 that stores hydrogen peroxide water, an evaporator 36 that evaporates the hydrogen peroxide water to generate hydrogen peroxide gas, and hydrogen peroxide water from the tank 35 to the evaporator 36. It is comprised with the pump 37 to supply. The decontamination gas generator 31 is an existing one and can be changed as appropriate.

  A blower fan 38 is disposed in the housing 30. The hydrogen peroxide gas generated by the decontamination gas generator 31 is mixed with the air sucked from the outside of the casing by the blower fan 38 and sent to the upper part of the casing 30.

  The upper part of the housing 30 constitutes a branch chamber 32 for branching hydrogen peroxide gas. The hydrogen peroxide gas passes through the HEPA filter 40 and then flows into the chamber from the opening 39 at the lower part of the flow dividing chamber 32. A connection port 13 for connecting the gas supply pipe 4 is formed on each side surface of the flow dividing chamber 32. A circular opening 34 is formed in the upper part of the flow dividing chamber 32, and the rotary emitter 5 is held in the opening 34 so as to be horizontally rotatable. The rotary emitter 5 is the same as the slave unit 3 and is driven to rotate horizontally by the motor 14 disposed in the housing 30. According to this configuration, the hydrogen peroxide gas generated from the decontamination gas generator 31 flows into the pipe 4 connected to the connection port 13 from the branch chamber 32 and flows into the upper rotary emitter 5. Then, it is discharged from the decontamination gas discharge port 6 to the periphery of the master unit 2.

  The pipe 4 connecting the parent device 2 and the child device 3 is made of a corrosion-resistant metal, and is connected to the connection port 13 of the parent device 2 and the child device 3 so that hydrogen peroxide gas is transferred from the parent device 2 to the child device 3. Supply. The pipe 4 includes a heating wire, and is heated to a temperature at which the hydrogen peroxide gas passing through the pipe 4 is not condensed by receiving power supply from the parent device 2.

  As described above, in the indoor decontamination apparatus 1 according to the present embodiment, the decontamination gas generated from the decontamination gas generation apparatus 31 of the master unit 2 is supplied to the decontamination gas discharge ports of the master unit 2 and the slave unit 3. Therefore, hydrogen peroxide gas generated by one decontamination gas generator 31 can be released from a plurality of locations in the decontamination target chamber. For this reason, even when the decontamination target chamber has a complicated shape, the decontamination target chamber can be efficiently decontaminated with a small number of decontamination gas generators.

  Moreover, since the subunit | mobile_unit 3 is not equipped with the decontamination gas generator 31, but is small, and the main | base station 2 provided with a decontamination gas generator can be installed in a difficult place, it is ideal for a decontamination object room. Decontamination gas can be released from the site.

  In addition, since the master unit 2 and the slave unit 3 are connected via a pipe 4 and each installation location can be flexibly changed in accordance with the shape of the decontamination target room, various decontamination target rooms can be appropriately set. Decontamination is possible. Moreover, since the main | base station 2 and the subunit | mobile_unit 3 are equipped with the caster 10 for a movement, installation to a decontamination object room, a change of an installation place, removal after decontamination, etc. can be performed easily. Further, the pipe 4 for supplying the hydrogen peroxide gas from the parent device 2 to the child device 3 includes a heating wire for heating the hydrogen peroxide gas so as not to condense in the pipe. The hydrogen peroxide gas can be reliably sent to the slave unit 3 without condensing.

  In addition, since the master unit 2 and the slave unit 3 are provided with the decontamination gas discharge port 6 that opens obliquely upward and includes the hollow rotary discharge body 5 that is driven to rotate horizontally, the base unit 2 and the slave unit 3 are efficiently provided around each body. Hydrogen peroxide gas can be released in a dispersed state. Moreover, since the adjustment plate 22 which adjusts the discharge | release height of hydrogen peroxide gas is arrange | positioned in the slit-shaped decontamination gas discharge port 6, the position of each adjustment plate 22 is set according to the chamber to be decontaminated. By adjusting, hydrogen peroxide gas can be more efficiently dispersed.

  In addition, the indoor decontamination apparatus of this invention can add a various change in the range which does not deviate from the summary of not only the form of the said Example but this invention. For example, the rotary emitter 5 of the embodiment includes a pair of decontamination gas discharge ports 6 that open obliquely upward. However, the rotary emitter according to the present invention may be one, or three or more. It doesn't matter. In addition to the decontamination gas discharge port 6 that opens obliquely upward, a decontamination gas discharge port 6a that opens directly above may be provided as in the rotary emitter 5a of the modification shown in FIG. Moreover, although the indoor decontamination apparatus 1 of an Example uses hydrogen peroxide gas as decontamination gas, the decontamination gas which concerns on this invention is not limited to this. Further, the number of parent devices and child devices can be changed as appropriate, and the number of parent devices is not limited to one. Further, the pipe connecting the master unit and the slave unit may be flexible. In addition, the decontamination gas supplied to the slave unit is not limited to a form directly supplied from the master unit, and may be indirectly supplied from the master unit via another slave unit. Moreover, although the indoor decontamination apparatus 1 of an Example is equipped with the decontamination gas decomposition | disassembly apparatus, a decontamination gas decomposition | disassembly apparatus is not an essential structure, and it is hydrogen peroxide gas in the exhaust system of the air conditioning of the decontamination object room C In the case of decomposing, the decontamination gas decomposing apparatus becomes unnecessary.
