Regenerative apparatus for activated carbon

The present invention relates to a regeneration device for honeycomb granulated pellets, and more particularly, to accumulate and use a plurality of honeycomb granulated pellets with a low risk of explosion, and to remove VOC gas adsorbed on the honeycomb granulated pellets. It is possible to regenerate the honeycomb type coal briquettes without separating them from the VOC removal device.Because the combustion gas with low oxygen concentration is used as the VOC desorption gas of the honeycomb type coal briquettes, There is little risk of explosion, the heat accumulating part and the catalyst part are formed inside so that the VOC gas can be burned at low temperature, and it is used in the initial temperature raising process because the combustion gas generated during the combustion of the VOC gas is used as a heat source. The present invention relates to a regeneration device of a honeycomb granulated coal which can be operated with as little fuel as possible.

In general, the detoxification treatment of wastewater and waste gas discharged from factories and the like has been an important problem in the past, but the pollution problem has recently emerged as the most urgent problem in recent years.

These harmless treatment methods have been studied separately, but the treatment using activated charcoal is extremely big.

Activated charcoal has a very high adsorption power, so if a desirable treatment agent or adsorption is sufficient, the adsorption power is saturated and regeneration is necessary to use it again.

In the conventional method of reactivating and reusing activated carbon, the activated carbon used in a rotary chiron heated outside by heavy oil burning is raised to 800 ° C or higher to carbonize the adsorbed material and at the same time blow high temperature steam. There was a method of regenerating by water gas reaction, but in order to complete the required regeneration treatment, heating was required for several hours at high temperature, considerable fuel consumption was required, and the cost of equipment was large, resulting in severe loss of activated carbon.

In addition, in order to regenerate activated carbon, activated carbon is separated from a volatile organic compound removal system. When the VOC or pyrolysis gas of the activated carbon encounters oxygen in the air, an explosion may occur, and the activated carbon is separated for regeneration. During this time, the problem of volatile organic compound removal system is stopped for a long time.

In addition, the conventional activated carbon uses granular or granular activated carbon, and as a cause of fire of the activated carbon, a fire occurs due to accumulation of adsorption heat due to solvent decomposition and ember formation due to static electricity between the activated carbon particles. In the case of granular activated carbon, the bottom portion is compressed when the vertically charged carbon is filled, and the upper portion is less compressed than the bottom portion.

The present invention has been made to solve the above problems, the object of the present invention is to remove the VOC gas adsorbed on the honeycomb granulated pellets without separating the honeycomb granulated coal, the risk of explosion Less, the heat storage portion and the catalyst portion is formed inside so that the VOC gas can be burned at a low temperature, and because the combustion gas generated in the combustion of the VOC gas is used as a heat source, less fuel used in the initial temperature rising process It is an object of the present invention to provide a honeycomb type granular regeneration device that can be operated only by using a bay.

Coal briquettes formed of a plurality of honeycomb granulated coal as a means for solving the above problems; A combustion chamber in which the VOC gas is burned; A supply pipe formed with a supply valve to supply the VOC gas, an air supply pipe formed with an air supply valve to supply air required for combustion of the VOC gas in the combustion chamber, and a discharge valve for discharging the combustion gas combusted from the combustion chamber; A heat storage unit including a discharge pipe formed and preheating the VOC gas supplied through the supply pipe to supply the combustion chamber; An exhaust pipe for discharging a part of the combustion gas discharged through the discharge valve to the outside; A first pipe connected to the exhaust pipe and provided with a circulation fan to circulate a part of the combustion gas not discharged through the exhaust pipe to the honeycomb granulated coal side; And a second pipe installed to move the combustion gas moved by the circulation fan to the combustion chamber by separating the VOC gas adsorbed to the honeycomb granulated coal.

As described above, the regenerating device of the honeycomb granulated coal uses a honeycomb granulated coal, and when the VOC gas adsorbed on the honeycomb granulated coal is removed, the honeycomb granulated coal is separated from the VOC removal device. If it is possible to regenerate without using the combustion gas with low oxygen concentration as the VOC desorption gas of the honeycomb granulated coal, there is less risk of explosion by VOC or honeycomb granulated coal during the regeneration process. A heat storage unit and a catalyst unit are formed therein to enable combustion at a temperature, and since the combustion gas generated during combustion of the VOC gas is used as a heat source, operation is possible with only a small amount of fuel used in an initial temperature raising process. By using the granulated coal of the type has the effect of reducing the risk of fire.
