Description

[Detailed Description of the Invention] The present invention relates to a disinfection gas adsorption device in a disinfection device for cultural properties, etc.

The present invention uses activated carbon to adsorb and remove the toxic components in the disinfectant gas after disinfecting cultural properties, etc., using a detoxification device, converting the remaining components into a clean gas, which is then released into the atmosphere. The purpose is to improve the adsorption efficiency by improving the contact efficiency of activated carbon with activated carbon, and to adsorb a large amount of components in a small adsorption cylinder.

To explain the details of the embodiment with reference to the drawings, Fig. 1 shows a schematic configuration of the sterilization device, and A is a sterilization room that is a room such as a building, although it is omitted. All the parts except for 1 are surrounded by concrete frame 1 and have a pressure-resistant structure.

All exposed concrete surfaces of this disinfection room A are covered with stainless steel plates or are coated with chemical-resistant resin or other chemical-resistant wall surfaces 2 to prevent disinfection gas from adsorbing and remaining.

The reason why such a chemical-resistant wall surface 2 is formed is that not only are alkaline particles emitted from the concrete and have a negative effect, but the concrete wall surface absorbs disinfectant gas, making it difficult to remove it and making the room extremely humid. This is because gas may be contained and condensation may occur due to changes in humidity.

Furthermore, when a stainless steel plate is stretched, it is necessary to back the U-t joint with a Teflon-based sealing material that has little gas adsorption.

Also, if the disinfection chamber has a welded structure, it is necessary to use a higher quality melt rod than the same steel material.

Although not particularly shown, there is a door on the front of the disinfection room A that can be easily opened using a rotating radiation rod, and the outer periphery of this door or the opening edge of the room is covered with Teflon as described above. Of course, a backing material of the type is also provided.

Although not particularly shown in the drawings, the wall surface of the front chamber where this door is provided is provided with an exhaust hole, an air inlet hole, a gas inlet hole, a detection hole, a hygrometer attachment hole, a pressure gauge attachment hole, etc.

3 is a disinfecting gas supply nozzle installed downward in the center of the ceiling of the disinfection room A, and below the disinfecting gas supply nozzle 3 is a disinfecting gas residual board B suspended from the ceiling. .

In the figure, C is a detoxification device for the disinfectant gas after use, and D is an adsorption device that adsorbs the remaining exhaust gas from which toxic components such as oxides have been removed in the detoxification device C and releases the purified exhaust gas into the atmosphere. cylinder, 4 I/'i pipeline connecting disinfection room A and detoxification device C, and 5 a pump installed in the pipeline.

6 is pulp, 7 is a switching valve, 8 is the switching valve 1
9 is a recirculation pipeline for the used sterilizing gas discharged from the sterilizing chamber A, and 9 is a recirculation pipeline for switching the exhaust from the adsorption cylinder to pulp 1.
This is a pipeline for circulating the disinfection chamber A through the disinfection chamber A.

Next, the structure of the suction cylinder will be explained with reference to FIGS. 2 and 3.

That is, the cylindrical body 12 is detachably attached to the pedestal 11.

The cylindrical body 12I/i is a rectangular bicylindrical type, and its shape is arbitrary, but dehumidification chambers 13 and 14 are provided in the upper and lower portions of the cylindrical body 12, respectively, in the shape of a normal cone and an inverted cone. The end of the pipe 15 for the gas that has passed through the detoxification device C is connected to the lower end of 14 via a damper valve 16, and the pipe 9 is connected to the top of the upper dehumidification chamber 13 via a damper valve 11. is connected.

The inside of this cylindrical body 12 is made of stainless steel perforated plate 18.
There is an adsorption chamber 19 partitioned into multiple stages by
Each adsorption chamber 19 is filled with activated carbon 20, and the upper and lower dehumidification chambers 13 and 14 are filled with a moisture-absorbing material such as cotton.

Furthermore, a ridge 22 in the shape of a bell is provided downward at the lower periphery of each hole 21 of each of the perforated plates 18, so as to obstruct straight passage of the gas.

On the upper surface of each perforated plate 18, a stainless steel mesh plate 23 in a tatami-weave shape is provided in a superposition manner to provide turbulent flow to the passage of gas.

In the figure, 24 is a sensor for measuring concentration inserted into each adsorption chamber 19.

Based on such a configuration, the function of the adsorption tube is described. The gas from which the toxic gas discharged from the detoxification device C of the detoxification device has been removed enters the lower dehumidification chamber 14 from below the adsorption tube, This will remove the moisture contained in the gas.
The gas rises and passes through the perforated plate 18 to the lowermost adsorption chamber 19.
to go into.

At this time, since a paris-shaped protruding edge 22 is provided at the lower peripheral edge of each hole 21 of the perforated plate 18, the gas is diffused by the protruding edge 22 and is further turbulently diffused by the action of the mesh plate 23. It rises while efficiently contacting the activated carbon 20 in the adsorption chamber 19 and removing components.

By performing such an action in the adsorption chamber 19 of each stage, the remaining components in the gas are completely adsorbed and removed, and the gas is completely purified by removing moisture again in the upper dehumidifying chamber 13. The gas is discharged into the atmosphere from the pipeline 9 through the damper valve 17, or is circulated back into the disinfection chamber A together with the disinfection gas by operating the switching valve 10.

In addition, if the function of the activated carbon becomes dull due to the sensor 24 and the gas concentration in the adsorption chamber 19 increases, the upper and lower damper valves 15 and 17 are closed and removed from the pipeline, and the entire adsorption tube is removed from the pedestal 11. The activated carbon 20 is taken out and incinerated at another location.

Then, the activated carbon that can be reused is used as is to make up for the shortage, and the moisture-absorbing materials such as cotton in the dehumidifying chambers 13 and 14 are replaced with new ones.

As described above, according to the present invention, the moisture contained in the exhaust gas is removed in the lower dehumidification chamber and then evenly dispersed by the perforated plate, allowing it to come into even and effective contact with the activated carbon filled in the adsorption chamber. Can be done.

Therefore, the components contained in the gas after use are completely adsorbed and removed by repeating this operation several times, and finally, the dehumidified and purified gas is returned to the upper dehumidification chamber. Not only can a non-polluting effect be expected due to the dissipation, but the practical effect is great, as it can also be miniaturized as a whole due to its high adsorption efficiency.
