The high-temperature inert gas sent into the main unit by the heat-resistant blower collects dust by the filter. In order to reduce the clogging of the heat-resistant metal mesh filter, one or more suitable vibration mechanisms should be installed at appropriate positions, and automatically or continuously intermittently operated under the control of automatic control equipment. By rotating arbitrarily,
Alternatively, by further moving up and down, an appropriate vibration is applied to an appropriate position inside or outside of any heat-resistant metal mesh filter in the above-mentioned various shapes. or,

Next, a filter formed by appropriately laminating a woven carbon or carbide filter having an appropriate mesh on an outer side thereof is formed into an appropriate cylindrical shape, and one or more of them are appropriately installed. In addition, a cooling pipe is appropriately installed inside the filter, and the filter is cooled in the same manner as described above to reduce damage due to high heat. This filter removes the odor contained in the high-temperature inert gas. Outside of this, a heat-resistant electrostatic charging filter (a suitable number of heat-resistant wires or plates with appropriate diameters and lengths or heat-resistant plates of appropriate shape and size using appropriate conductors are arranged in an appropriate number of cylindrical shapes. Or staggered numbers,
A ring-shaped conductor heat-resistant plate with an appropriate diameter, width, and thickness is installed appropriately above and below this, and these are installed and installed appropriately, and then these are installed so that they can be charged with static electricity.) Insulate and install multiple units appropriately,

Make it possible. As for clogging removal, the use of automatic control equipment, etc. automatically detects the occurrence of clogging based on signals from a high-pressure static pressure air pressure detection device installed in the suction duct of each device, and automatically and heat-resists. Switching of automatic damper, switching of electricity supply from static electricity generator, switching of refrigerant line of cooling equipment / device, etc., switching operation from clogging generator to another device, collecting dust, and automatically generating clogging The clogging removal process of the device is started. First, stop charging the heat resistant electrostatic charging filter, peel off and drop the micro mist, and operate one or more vibrating mechanisms appropriately to give appropriate vibration to the heat resistant metal mesh filter, Peel and drop dust. The separated micro mist and dust are collected in a heat-resistant hopper at the lower part of the apparatus and are discharged to a lower shooter by operating a heat-resistant automatic rotary valve or the like. In addition, the heat-resistant blower of the clogging device is operated in the appropriate reverse rotation, exhausted from the intake duct, and the inside of the device is backwashed, so that the micro mist is further separated and dropped, and the dust is further separated and dropped. Discharge. In addition, by appropriately switching the heat-resistant automatic damper, the floating dust is collected by the operating device. By installing a heat-resistant dust collector with cyclone before the intake and dust collection process by this device, and by collecting dust in advance, the amount of dust sucked into this device is reduced and the cycle of clogging is prolonged. The temperature of the high-temperature gas is also reduced, and the deterioration of the function over time due to thermal damage of the present apparatus can be reduced.

Install it moderately. In addition, an appropriate vibration mechanism will be installed at an appropriate position, and automatically and continuously or moderately intermittently operated under the control of automatic control equipment, so that appropriate vibration can be applied. The bearing portion of the vibration applying mechanism is cooled by an appropriate refrigerant such as water. Next, as shown in FIG. 2, a woven activated carbon filter having an appropriate mesh and an appropriate mesh size is appropriately laminated on the outside of the filter, molded into a cylindrical shape, and installed. In addition, as shown in FIG. 3, a cooling pipe is appropriately installed in the inside, and the cooling is appropriately performed in the same manner as in the bearing of the vibrating mechanism.

The system is constructed so that operation switching, switching of electricity supply from the static electricity generator, switching of refrigerant lines by cooling equipment and devices, and the like can be performed, thereby enabling operation of another device.
In addition, the clogging device is automatically operated, with the appropriate operation of the vibrating mechanism, the stop of static electricity charging, the proper operation of the heat-resistant automatic damper, the reverse rotation of the heat-resistant blower, and the reverse blowing, and the dust is peeled off.・ Clogging is removed by dropping / discharging and floating dust and the like being collected in the operating device, so that the device can be operated alternately and continuous dust collection becomes possible.
