It includes a first shut-off valve and a control unit provided on one side of the main body, which controls the operation of the suction means, shutter, high-pressure blower, and the first shut-off valve according to selected operation modes. When the selected operation mode is a recovery mode, the control unit opens the shutter and operates the suction means while the first shut-off valve is closed so that the recovered adsorbent is collected. When the selected operation mode is a charging mode, the control unit closes the shutter, opens the first shut-off valve while the charging adsorbent is contained inside the collection container, and operates the high-pressure blower so that the charging adsorbent can be supplied into the dust collection facility. According to the present invention, the recovery and filling process of carbon-based adsorbent particles, which was previously performed manually by workers using tools such as coal shovels in an adsorption tower dust collector, is carried out by utilizing the suction and discharge pressure of the fluid, thereby having the advantage of significantly reducing input personnel, labor, and time required.

Description

Mobile carbon-based sorbent recovery and charging device The present invention relates to a mobile carbon-based adsorbent recovery and filling device capable of recovering and filling a carbon-based adsorbent contained in a carbon adsorption facility. In general, carbon adsorption facilities utilizing carbon adsorption methods are operated to reduce atmospheric emissions of volatile organic compounds (VOCs) and other substances generated in the chemical and petrochemical industries. As the above volatile organic compounds (VOCs) are hydrocarbon compounds that cause environmental pollution by generating ozone ( O3 ), which is the cause of photochemical smog, through photochemical reactions with nitrogen oxides (NOx) and other chemicals in the atmosphere, carbon adsorption facilities filled with carbon-based adsorbents are being operated. Meanwhile, FIG. 1 shows a drawing illustrating an example of an adsorption tower dust collection facility installed at a VOC generating workplace, and FIG. 2 shows a photograph illustrating a cleaning operation being performed to replace a carbon-based adsorbent contained inside the adsorption tower shown in FIG. 1. As illustrated in these drawings, in the adsorption tower dust collector installed at the workplace, contaminated air from the site is introduced through the inlet, filtered by carbon-based adsorbent material filled inside, and then discharged as purified air through the outlet. In other words, air containing volatile organic compounds (VOCs) is adsorbed in the active regions of carbon, and carbon-based adsorbents for this purpose can be formed from natural materials such as wood, coconut shells, or peat, and can be manufactured by using steam or phosphoric acid to form activated carbon with a large porous structure into granular or pellet forms. Meanwhile, carbon-based adsorbents with the above-mentioned characteristics become saturated with carbon and their efficiency decreases after use for a certain period of time. Accordingly, the adsorption tower dust collector is operated by periodically recovering the saturated carbon-based adsorbent and refilling it with new or regenerated carbon-based adsorbent (C), and this recovery and refilling process is generally carried out by on-site workers as shown in FIG. 2. However, as described above, when recovering carbon-based adsorbents contained inside the adsorption tower by field workers, there is a problem in that the workspace is narrow and the work is performed relying on the worker's ability, requiring a significant amount of time and effort. In addition, poor working conditions are created due to dust dispersion and heat generated during the work process, and in particular, in the case of clean carbon-based adsorbents that have never been used, adsorption reactions can occur in which the temperature rises up to 1200℃, posing a problem of high work risk. FIG. 1 is a drawing showing an example of an adsorption tower dust collection facility installed at a VOC generating workplace. Figure 2 is a photograph showing the cleaning process for replacing the carbon-based adsorbent contained inside the adsorption tower illustrated in Figure 1. FIG. 3 is a drawing showing an embodiment of a mobile carbon-based adsorbent recovery and filling device according to the present invention. FIG. 4 is a drawing for explaining the variable structure of the nozzle section and the control section in FIG. 3. FIG. 5 is a drawing for explaining an adsorbent suction structure using an embodiment according to FIG. 3. FIG. 6 is a drawing for explaining an adsorbent replacement filling structure using an embodiment according to FIG. 3. FIG. 7 is a drawing for explaining a cooling fluid injection structure using an embodiment according to FIG. 3.
