- the outer passage 511), the connection passage 51c, the inner passage 5la, and the heat radiating member 52 are the coolers referred to in the range of the patent request.
- the recirculator 7 is not limited to the above configuration, and is not particularly limited as long as the fluid sucked by the suction unit 50 can be cooled and then supplied to the pump 12 or the like. There is no particular limitation on the position of the installation.
- suction unit 50 used for treating heat-sensitive harmful substances will be described.
- a fluid passage 51 having a distal end communicated with the outside and a proximal end communicated with the hose 11 is formed at the center of the suction portion 50.
- a heater 54 capable of heating fluid flowing in the fluid passage 51 such as a heater or a gas nozzle, is provided.
- the harmful substance contained in the sucked fluid is a bacterium or the like that is sensitive to heat, it can be treated in the fluid passage 51 of the suction section 50.
- treatment of harmful substances Since it can be carried out by both the suction unit 50 and the harmful substance treatment means 30, it is possible to reliably treat heat-sensitive harmful substances and reduce the burden on the harmful substance treatment means 30 .
- a cooler 55 is provided between the fluid passage 51 and the hose 11, it is possible to prevent the heated and high-temperature fluid from flowing to the pump 12 and the like.
- suction unit 50 used for processing harmful substances such as chemical weapons will be described.
- a fluid passage 51 having a distal end communicated with the outside and a proximal end communicated with the hose 11 is formed at the center of the suction portion 50.
- a filter portion 56 for adsorbing harmful substances contained in the sucked fluid is provided at the base end of the fluid passage 51.
- the filter unit 56 includes a pre-processing unit 57 made of activated carbon and soda lime, and a post-processing unit 58 made of felt.
- the harmful substance treatment system 1 of the present embodiment is installed in the premises of a station, a factory, a building, or the like, rapid treatment can be performed when a harmful substance is generated, as shown in FIG. If installed on transportation means such as trucks, trailers, and towing trolleys, they can be quickly moved to the site where harmful substances are generated. Therefore, even if a harmful substance is generated in a place where the harmful substance treatment system 1 is not provided, the harmful substance can be promptly treated, and the damage can be prevented from spreading.
- a fluid containing a harmful substance can be sucked by the sucking bow I means and then treated by the harmful substance treatment means, and the fluid that has been cleaned after treating the harmful substance can be discharged.
- Harmful substances can be treated without adversely affecting people in the area, and the surrounding environment can be prevented from being polluted by the discharged fluid. Can be prevented.
- even harmful substances can be reliably treated.
- the harmful substance can be sucked together with the fluid, even if the harmful substance easily diffuses into the fluid, the harmful substance can be prevented from diffusing, and the damage can be effectively prevented from spreading.
- the harmful substance can be quickly moved to the site where the harmful substance is to be treated because it is mounted on the transportation means.
- harmful substances can be promptly treated, so that damage can be prevented from spreading.
- the harmful substance treatment system of the third aspect of the invention can remove powder and particles contained in the fluid such as smoke and dust and then release it to the atmosphere. It can prevent pollution and prevent the occurrence of secondary disasters.
- the surrounding environment can be prevented from being polluted by the discharged fluid, and secondary disasters and the like occur. Can be prevented.
- the harmful substance can be neutralized by the neutralization device, so that the fluid can be discharged as a fluid having no adverse effect on the human body. it can.
- the harmful substance can be treated by a catalytic reaction, so that the harmful substance can be efficiently and reliably detoxified. Then, since the fluid is supplied after the suspended solids are removed by the suspended solids removing device, it is possible to prevent the catalytic device from becoming dirty and soot or the like from being deposited, thereby lowering the catalytic function.
- the fluid can be heated to 100 ° C. or more by the heater, any harmful substance that is weak to heat, such as a substance that is easily decomposed by bacteria or heat, can be used as a catalyst device. To make it harmless.
- the fluid can be passed through both the neutralization device and the catalyst device. Then, if the harmful substance is destructive or alkaline, it can be reliably neutralized by the neutralization device. Any neutral substance that can be decomposed by heat can be decomposed and rendered harmless by a catalytic device. Therefore, a single processing system can process a fluid containing a plurality of harmful substances, so that a fluid containing harmful substances can be easily and efficiently processed. Further, if the first flow path switching means is switched to form a detour path, the suction means and the floating substance removing device can be directly communicated.
- the fluid can be directly supplied to the suspended solids removal device without passing through the neutralization device. The occurrence of a normal reaction can be prevented. Further, if the second flow path switching means is switched to form a detour path, the floating substance removing device and the discharging means can be directly communicated. Then, if the harmful substance can be treated only by the neutralizing device and the suspended matter removing device, it is not necessary to operate the catalyst device, so that the harmful substance can be treated efficiently.
- the optimal path is selected by the path selection unit according to the type of the harmful substance, and the first path switching unit is switched by the switching unit operating unit. And the second channel switching means is switched. For this reason, the processing of the harmful substances can be performed reliably, and mistakes in the route selection in each channel switching means can be prevented.
- the detection means detects the type of the harmful substance, so that the path through which the fluid passes can be more quickly and reliably selected. According to the eleventh invention, even if a very high temperature fluid containing harmful substances, such as air at a fire spot, is sucked, the fluid is cooled by a cooler and then supplied to a pump or a toxic substance treatment means. Therefore, the pump and the like can be prevented from being damaged by the high-temperature fluid.
- the twelfth aspect even if air or the like in a place where a flame exists, such as a fire spot, etc., it is possible to inhale only a fluid containing harmful substances without absorbing the flame.
- the part and the pump can be prevented from being damaged by the flame.
- the treatment of harmful substances can be performed by both the suction part and the harmful substance treatment means, so that harmful substances that are sensitive to heat can be removed.
- the treatment can be performed reliably, and the burden on the hazardous substance treatment means can be reduced.
- harmful substances contained in the sucked fluid can be adsorbed also in the filter section.
- harmful substances can be treated by both the suction unit and harmful substance treatment means, so that harmful substance treatment can be ensured and the burden on the harmful substance treatment means can be reduced. Can be.
