The waste activated carbon collection and transportation step is to collect and transport a large amount of waste activated carbon including water from the regeneration tank, and the regeneration tank of the purification and purification facility for drinking water is far from the regeneration system 100 for regenerating the waste activated carbon. In the case of a remote location, the activated carbon collection vehicle 10 using vacuum pressure sucks and transports the activated activated carbon in large quantities including water and air from the regeneration tank of the purification and purification facility for drinking water. In addition, when the regeneration tank of the drinking water purification and water purification facility is located near the regeneration system 100 for regenerating the waste activated carbon, one end of the waste activated carbon collection pipe is charged into the regeneration tank by using a diver or the like. In addition, the other end of the waste activated carbon collection pipe is connected to a portion where waste activated carbon is supplied from the regeneration system 100 to directly supply the waste activated carbon to the regeneration system 100.

Here, the activated carbon collection vehicle 10 may be a vehicle of various types, but the activated carbon is sucked into the collection tank using vacuum pressure and stored therein, and the activated carbon in the collection tank is regenerated by pressurizing the high-pressure water discharge device. It is preferable to use the one disclosed in the Republic of Korea Utility Model Registration No. 20-0231124 that can easily suck, transport, and discharge activated carbon by discharge into the tank for smooth collection and transportation of waste activated carbon.

The waste activated carbon transfer step receives a large amount of waste activated carbon from the activated carbon collection vehicle 10 or the waste activated carbon collection pipe, stores the waste activated carbon in the waste carbon storage tank 220, and then uses the high pressure water pump 260 in the waste carbon storage tank 220. The stored activated carbon is pumped onto the transfer pipe 240 to move to the dewatering conveyor 320.

In the present invention, as the waste activated carbon is collected and supplied in a large quantity, a separate waste carbon storage tank 220 is provided to store the waste activated carbon and then moved to the next step. Most of the activated carbon used in the purification and drinking water regeneration tanks for drinking water is granular activated carbon, and the granular activated carbon transfers the granular activated carbon as it has little suction force to suck foreign substances when the particle state becomes smaller than the standard. When passing through a pipe, such as 240, always passes with water to minimize the friction by minimizing friction. Accordingly, the activated activated carbon containing water is pumped to the transfer pipe 240 using the high pressure water pump 260.

It is lowered up and down in a zigzag form through the opening portion 429, and the seating plate 425 rotates in a spiral orbit to move to an end portion, thereby maximizing the movement trajectory of the waste activated carbon, thereby increasing the heating and drying efficiency of the waste activated carbon.

The regeneration activated carbon quenching step is a step of quenching the regenerated activated carbon discharged from the lower end of the multi-stage activated carbon regeneration furnace 420 into a cooling tank 520 filled with cooling water, and heat-dried to a high temperature state. By heating the regenerated activated carbon by quenching, the granular size of the regenerated activated carbon is continuously maintained. This is to prevent the phenomenon in which the activated activated carbon is broken finely and the adsorptivity of the activated activated carbon becomes low while the activated activated carbon is slowly cooled by contact with air.

In the regeneration activated carbon transfer step, the quenched regenerated activated carbon is pumped onto the transfer pipe 640 by using the high pressure water pump 660 and stored in the regenerated coal storage tank 620 and then back to the transfer pipe 640. Moving to the upper side of the dewatering conveyor 720, and temporarily stored in the regeneration carbon storage tank 620 for the smooth discharge of the regenerated activated carbon generated in large-sized activated carbon regeneration furnace 420, if necessary Therefore, a certain amount of pressure is discharged to the outside.

The regenerated activated carbon dehydration step is to load the regenerated activated carbon on the dewatering conveyor (720) to transport the water, and the dehydration conveyor (720) has the same configuration as the dewatering conveyor (320) of the waste activated carbon dewatering step. In order to increase the transport efficiency by reducing the weight by removing the water contained in the regenerated activated carbon in the next step of transporting the regenerated activated carbon.

The regeneration activated carbon transporting step is to transport the regenerated activated carbon removed from the water to a predetermined size or loaded in a separate storage box and transported to the regeneration tank of the purification and purification facilities for drinking water, thereby completing the regeneration process of waste activated carbon. do.
