Description

CARBONIZING APPARATUS FOR ACTIVATED CARBON ", which is a screw supply type,

The present invention relates to an activated charcoal furnace for separating and extracting contaminants adsorbed on waste activated carbon to obtain microporous activated carbon. In the present invention, uniform supply of raw materials is carried out by screws in a multi-stage horizontally arranged deck, In the combustion chamber, the combustion air of the adsorbent contaminants is extracted by inducing the heat and the mutual contact of the air inside the combustion chamber, and the residual gas which has not been completely burned is collected and re- To an activated char combustion furnace of a screw supply type in which complete combustion is performed.

Activated carbon is a special carbon that is calcined activated at high temperature using mainly coconut shells and coal. It is a collection of amorphous carbon with fine pores of well-developed molecular size during the activation process.

These activated carbons can be used in various fields such as gas masks for removing toxic gases, adsorption devices for removing harmful gases in general industrial facilities, equipment systems for adsorbing and removing radioactive iodine from nuclear facilities, related devices for preventing water pollution, (SOx, NOx, CO2, H2S, mercury gas) generated in general industry facilities, it is necessary to add various metal salts to raw activated carbon and to improve the activity of metal salts Add chemical additives to remove harmful gases by adsorption reaction.

However, these apparatuses are not only expensive but also have a very small amount of energy to be used as compared with the amount of energy used. Resulting in a fatal problem of non-economic.

For example, rotary kiln and multi-stage furnace are used for the production of activated carbon. The initial warm-up time is 2 to 4 hours, In order to produce the product in the method of sparking, it takes more than 24 hours to reach the proper temperature, and if the production is terminated afterward, it takes the same time even after the fire extinguishment, There is a fatal problem. In addition, since the heat transfer is transmitted from the outside to the inside of the particle, the loss due to the expansion of the product due to heat and the particle damage due to the surface friction of the inside of the furnace and the activated carbon increases, resulting in a decrease in production yield and a high production cost.

In the case of a multi-stage furnace for carbonizing waste activated carbon, conventionally, only a small amount of raw material is handled, which is consistent with a fall-type carbonization structure in a conventional manner. In particular, a temperature setting must be separately provided for each deck And the remaining heat source is consumed as waste heat after the hassle and the process, resulting in a great deal of energy efficiency.

And throughout this specification, like reference numerals refer to like elements throughout.

The present invention relates to an activated charcoal furnace (200) for separating and extracting contaminants adsorbed on a waste activated carbon to obtain a microporous activated carbon.

In particular, in the present invention, uniform supply of raw materials is performed by a screw in a deck horizontally arranged in multiple stages, and combustion and extraction of adsorbed contaminants are performed by inducing heat and air to each other in the combustion chamber, The present invention relates to a screw supply type activated carbon furnace 200 in which residual gas is collected and reused to continuously supply the residual heat to the drying furnace.

As shown in Figs. 1 to 3, the activated carbon char combustion furnace proposed in the present invention is a multistage multi-stage furnace of nine stages, and is provided with an upper two stages in which the supply is performed, a middle stage in which carbonization takes place, And lower two stages where cooling is performed. Hereinafter, detailed description will be given with reference to the related drawings.

2 to 3, the activated carbon char combustion furnace 200 separates and extracts contaminants adsorbed on the waste activated carbon to obtain a microporous activated carbon, and includes a supply part 210 for uniformly introducing the raw material by horizontally arranged screws And a combustion unit 220 for performing combustion and extraction of the adsorbed contaminants through contact with the air through the heat source supply unit 221 while sequentially moving the raw materials introduced from the supply unit by the horizontally arranged screws A primary combustion chamber 230 for supplying the fuel; The raw material that is formed in the lower part of the primary combustion chamber and is passed through the primary combustion chamber is moved by the screw, and the steam is supplied to the raw material and is sucked and activated. As a result, the raw material is formed into microporous activated carbon. A cooling part 240 for cooling the cooling part 240; And a secondary combustion chamber 250 which is formed above the primary combustion chamber so as to collect residual gas which has not been completely burned in the primary combustion chamber and can be secondary-burned by the heat source supply section 251. [

In the case of a multi-stage furnace for carbonizing waste activated carbon, conventionally, it is consisted only of a fall-type carbonization structure in a uniform size, There is a problem that only a small amount is handled, and there is a great disadvantage in terms of energy efficiency such as the necessity of separately providing the temperature setting for each deck and the remaining heat source as waste heat.

Accordingly, in the present invention, the raw material is uniformly supplied to the decks horizontally arranged in multiple stages by the screw, and the activated carbon char combustion furnace 200, in which combustion of the adsorbing contaminants can be performed by inducing heat and air to each other in the combustion chamber, And the residual gas which has not been completely burned is collected in the primary combustion chamber 230 and re-burned through the secondary combustion chamber 250, thereby achieving complete combustion of the gas.

In addition, the reheated heat generated at this time can be continuously supplied to the drying furnace, thereby realizing the recycling of the heat source positively.

That is, the upper secondary combustion chamber 250 is formed in association with the drying furnace in which the drying of the raw material is performed, so that the hot residual heat due to the gas combustion can be continuously supplied to the drying furnace.

The upper primary combustion chamber 230 is maintained at a predetermined temperature by the heat source supply unit 221, and a plurality of decks transversely arranged in the horizontal direction are constructed as one path passing through from the upper side to the lower side.

For this purpose, the upper primary combustion chamber 230 is connected to the secondary combustion chamber 250 and includes first and second decks 211 and 212 for receiving screws corresponding to the respective decks for metering the raw materials. The first, second, third, fourth, fifth, sixth, and seventh decks (the first, second, third, fourth, fifth, sixth, and seventh decks) for sequentially moving the raw materials flowing in the first and second decks, 213, 214, 215, 216, 217).

On the third, fourth, fifth, sixth, and seventh decks 213, 214, 215, 216, and 217, nozzles 218 for discharging gas extracted from the raw materials are drilled at regular intervals, The discharged gas comes into contact with air in the space between decks corresponding to the inside of the primary combustion chamber 230 and is heated or ignited to induce heating of neighboring decks.

The first and second decks 211 and 212 serve to control the screw rotation speed of the first and second decks 211 and 212 while controlling the amount of the raw material to be supplied. In this case, the first and second decks 211 and 212 are relatively slow And a function of heating the raw material to a high temperature by the heat source supply unit 221 is performed.

The screw rotating speed of the third, fourth, fifth, sixth, and seventh decks 213, 214, 215, 216, and 217 is operated at a speed 2 to 4 times faster than that of the first and second decks. That is, when the raw material fed and fed at low speed in the first and second decks enters the third deck 213, the raw material spreads widely at the inner surface of the third deck, Carrying gas is generated as it is secured.

Such a dry gas is discharged through the nozzle 218 of the corresponding deck in a densely packed state, and is combusted with the outside air.

Also, as shown in the drawings, the third to seventh decks are provided with a structure for heating neighboring upper decks as the carbon dioxide gas generated from the deck located at the lower side is burned. In order to allow this structure to be carried out in a limited combustion state, the raw material is transferred through the inside of the high-temperature deck, resulting in carbonization, so that the carbon burning is extremely small and the ash is hardly generated. .

The upper cooling section 240 is divided into 8th and 9th decks, and the 8th and 9th decks are sections where the raw material heated to a high temperature is activated.

Activated carbon obtained by discharging all pollutants adsorbed by the raw material and heated to high temperature (800 to 900 ° C) is activated as micro-pores are generated as steam is supplied before cooling, and is activated in the cooling water tank Lt; / RTI > As described above, the cooling unit 240 is configured to be cooled by the cooling water tank 241 while moving to the eighth and ninth decks configured to be activated with the raw material heated to a high temperature. As a result, The first and second decks 211 and 212 and the third, fourth, fifth, sixth and seventh decks 213, 214, 215, 216 and 217 of the primary combustion chamber 230 and the eighth and ninth decks of the cooling unit 240, And the raw material is configured to be moved in multiple stages in the zigzag direction between the respective decks (first to ninth decks).

For example, the screw speeds of the first and second decks 211 and 212 proposed by the present invention are set to be slower than the screw speeds of the third, fourth, fifth, sixth, and seventh (213,214,215,216,217) decks, It is preferable to increase the surface area of the material to be contacted with each deck while expanding the material starting from the third deck 213 as the moving speed of the material placed in the third deck is increased.

According to the activated charcoal furnace 200 of the present invention having the above configuration, the raw material is uniformly supplied by the screw in the multi-stage horizontally arranged deck, and the raw material can be handled in a large amount compared with the conventional deck .

Further, the present invention can induce heat and air contact with each other inside the combustion chamber, which is an outer region of each deck, to perform combustion extraction of adsorbed contaminants, resulting in extremely reduced ash generation, So that the work efficiency can be enhanced.

In addition, according to the present invention, residual gas that has not been completely burned in the primary combustion chamber 230 is trapped and re-combusted through the secondary combustion chamber 250 to achieve complete combustion of the gas and to continuously supply the residual heat generated at this time to the drying furnace And thus it has a great effect such as energy saving and fuel saving.
