Definitions
- the present invention relates to a method and an apparatus for regenerating used activated carbon.
- Activated carbon has a very high adsorptive power and is a very preferred treatment agent. However, if the adsorp- tion is performed sufficiently, the adsorptive power is saturated, and it is necessary to regenerate it for further use.
- activated carbon is activated and regenerated by using activated carbon in a ⁇ -talli kiln that is heated externally by burning heavy oil or the like to raise the temperature of the activated carbon to 800 ° C or more to remove adsorbed substances.
- a method of regenerating by water gas reaction by blowing high-temperature steam is a method of regenerating by water gas reaction by blowing high-temperature steam.However, in order to complete the desired regeneration process, several hours at high temperature Requires considerable heating, requires considerable fuel consumption, requires large equipment costs, and causes significant loss of activated carbon itself.
- the present invention provides a method for activating and regenerating used activated carbon by the spark discharge.
- adsorbents can be recovered without decomposing by desorbing at a relatively low temperature, and harmful and unnecessary adsorbing substances can be desorbed at a high temperature and decomposed or burned on the spot.
- a pulsating motion to the activated carbon particles together with the application of the pulse voltage the generation of spark discharge and, consequently, the desorption action of the adsorbed substance is promoted.
- a weir plate is provided at an appropriate location in the oscillating activated carbon transport path to temporarily block the flow of the activated carbon and to remove the adsorbed material. Particles that have become lighter due to separation are selectively passed over the crest plate sequentially.
- FIG. 1 is a front view showing an embodiment of the activated carbon regenerating apparatus according to the present invention
- FIG. 2 is a side view of the same
- FIG. FIG. 5 is a layout diagram showing an example of a wastewater purification device using a regeneration device
- FIG. 5 is a waveform diagram of an applied voltage.
- (1) is a box-shaped desorption tank whose bottom is inclined at an appropriate angle in the longitudinal direction, and a light caster made by Pli Plico is installed on the inner surface of the bottom.
- a refractory mortar, such as a plycaster, or other refractory (2) such as a refractory wrench with good greenery is lined to form a groove-shaped transport path ().
- the plate-like carbon electrodes (3), (3), ... are arranged in opposition to each other, and a rod-like electrode or the like can be used instead of the plate-like electrode.
- the lower end of the inclined bottom surface of the desorption tank (1) is mounted on the eccentric shaft (11 ') of the rotating shaft (11) supported by bearings (10), (10) on the base frame (9). (12), (12), and the rotating shaft (11) is pre-mounted 3 ), belt (M) and
- a pulse voltage E is applied as shown in Fig. 5.
- the pulse voltage or the pulse voltage and the oscillating motion are combined.
- a large amount of spark discharge is generated between the activated carbon particles, and the desorption of the adsorbed substance is performed within a very short time of several to several minutes.
- One-sided thyristor, thyristor-leonard type, etc. are used (in this embodiment, the thyristor-chopper type was adopted).
- the temperature during the desorption process can be controlled by adjusting the pulse width (t).
- t the pulse width
- the applied voltage may be an AC waveform as shown in FIG. 5, or a DC waveform without pole conversion.
- the spent activated carbon thus fed is dammed by each dam (4), and the adsorbed substance is desorbed during the repetition of the rocking motion ⁇ J, and the lightened particles float upward.
- the evacuation progresses sequentially, and finally, most of the adsorbed substances are desorbed, and the activated carbon that has been almost completely activated and regenerated is transported. Removed from mouth (6).
- the desorption tank (1) having the weir plates (4), (4)... Can be used also in the reproducing apparatus using the normal voltage application and vibration according to the prior invention.
- Fig. 4 shows an example of a continuous purification system for wastewater using the activated carbon regeneration device of the present invention.
- (19) is an adsorption tank using activated carbon (20) as an adsorbent
- (21) is a dryer
- (22) is a dryer.
- a tank for storing charcoal, ( 24 ) is a transport pump, and-a dryer (21) having the same structure as the regenerator ( 22 ) in this example is used, and a dehydrator having a receiving net at the top is used.
- a vessel ( 25 ) is provided, a normal direct heating type or a drying oven using hot air may be used.
- the raw water flowing from the raw water intake (26) of the adsorption tank (19) passes through the filter net (27) and the harmful substances while passing through the packed bed of the adsorbent (20). Is removed by adsorption * and discharged from the outlet (28) as purified water.
- the adsorbed activated carbon (20) is taken out from the outlet at the bottom of the adsorption tank-(29) by the impregnated fixed-quantity sampler (30) in a fixed amount every predetermined time into the dehydrator (23). Is removed and then dried in a drier (), and if necessary, the slag is carbonized or incinerated in this section, and then a regenerator (23).
- the activated carbon regeneration method of the present invention by applying a pulse voltage, it is possible to generate a spark discharge between the activated carbon particles and efficiently desorb the adsorbed substance. , And at that time, the applied voltage
- the pulse width was adjusted without changing the intermittent cycle. Cycle was used in the range of 5 0-4 0 0 rhino click Le.
