Description

Collective activated carbon recycling and integrated energy recycling system

The present invention relates to a system that allows the regeneration process of activated carbon cartridges to be co-intensively and intensively, and at the same time recycles the waste heat generated in the regeneration process to the activated carbon regeneration, cooling, heating or recycling.

When volatile organic compounds (VOCs) are released into the atmosphere as they are, they react with light to produce photochemical oxides such as ozone, aldehydes, or nitrogen compounds in smog, resulting in environmental pollution such as photochemical smog and global warming in large cities. In addition, most of the volatile organic compounds that make up volatile organic compounds produce irritating and unpleasant odors even at low concentrations. Legal emission regulations are being established for these facilities.

In the treatment of such volatile organic compounds, adsorption methods using activated carbon are generally used. Since activated carbon has a myriad of fine pores and a large surface area, volatile organic compounds having a relatively high molecular weight such as benzene, toluene, and xylene gas are used. Compounds are also allowed to adsorb in a condensed state.

On the other hand, activated carbon having such characteristics is that when volatile organic compounds are continuously adsorbed and the activated carbon is saturated, its inherent adsorption capacity is inevitably lost. Therefore, when the activated carbon of the adsorption apparatus is saturated, it must be replaced with new activated carbon. Since the cost of the activated carbon is relatively high, it is preferable to regenerate the activated carbon by desorbing the volatile organic compound adsorbed on the activated carbon.

As an example of a technology for regenerating activated carbon, Korean Patent Registration No. 0492070 constitutes a circulation line including a space in which activated carbon is disposed, and activates activated carbon at a high temperature while circulating hot air in the circulation line, thereby volatile organic compounds in activated carbon. It is a tropical flow type regeneration device which is designed to extract the gas, and is installed on the exhaust line of the facility that discharges the exhaust gas containing volatile organic compounds, and can be selectively sealed by the inlet side damper and the outlet side damper. A chamber having a constant volume for accommodating multiple stages of activated carbon therein, a circulation line for circulating air in the chamber while passing through one upper portion and the other lower portion of the chamber, and a fan for forced circulation, and installed at one side of the circulation line Supply heat exchanger and heat source for heat exchange of circulating air It presents the structure of the sprinkler, such as the number of lines for injecting a heater and, when activated carbon overheating water.

However, most SMEs use activated carbon, but the capacity of activated carbon is so small that it is practically impossible to have a regeneration device such as the above technology. Description of the device is required. In addition, since the recycling of waste heat generated in the activated carbon regeneration process is not widely proposed in the above technology, such a technology is required in the future.

This allows the reproduction to be performed jointly and continuously.

In the present invention, the activated carbon regeneration device 2 is not limited to a kind thereof, and a hot air drying device or a steam drying device may be used. In the case of a steam drying apparatus, various well-known techniques are proposed, and description thereof will be omitted.

In particular, the present invention provides an embodiment of the hot air drying device (2, the same reference numerals for convenience as the activated carbon regeneration device) as the activated carbon regeneration device 2, hereinafter hot air drying device ( Explain 2).

The hot air drying apparatus 2 of the present invention has a desorption chamber 21 for desorbing a volatile organic compound from the activated carbon cartridge 12 as shown in FIG. 12, and an activated carbon cartridge 12 that is desorbed in association with the desorption chamber 21. While communicating with the cooling chamber 22 for cooling the flow, the flow means 23 for flowing the activated carbon cartridge 12 so as to pass through the desorption chamber 21 and the cooling chamber 22 in sequence, and the desorption chamber 21. Desorption outflow that outflows the air containing the volatile organic compounds desorbed from the activated carbon cartridge 12 while communicating with the desorption chamber 21 and the high temperature inlet line 24 for injecting hot air into the activated carbon cartridge 12. Line 25, a cooling inlet line for injecting cooling air into the activated carbon cartridge 12 while communicating with the cooling chamber 22, and preheated air passing through the activated carbon cartridge 12 while communicating with the cooling chamber 22.

In the desorption chamber 21, the activated carbon cartridge 12 flows from the first inlet 211 to the first outlet 212 by the flow means 23, so that the hot carbon inlet flows into the activated activated carbon cartridge 12. The hot air is injected through the line 24, and the volatile organic compound is desorbed from the activated carbon cartridge 12 flowing by the hot air. The desorbed volatile organic compound is sent to the treatment unit 3 through the desorption and discharge line 25 together with air, and removes the volatile organic compound by combustion of the treatment unit 3.

The activated carbon cartridge 12 in which the volatile organic compound is desorbed by the high temperature air has a risk of fire when exposed to the air due to a heat factor. In the present invention, the activated carbon cartridge 12 is directly cooled to the cooling chamber 22. ), The desorption chamber 21 and the cooling chamber 22 are connected by the cover 29 to prevent the desorbed activated carbon cartridge 12 from being exposed to the atmosphere.

The cooling chamber 22 is formed with a second inlet 221 on one side and a second outlet 222 on the other side, and the flow means 23 allows the cooling chamber 22 from the second inlet 221. It is configured to penetrate through the second outlet 222.

In the cooling chamber 22, the activated carbon cartridge 12 desorbed from the second inlet 221 to the second outlet 222 is flown by the flow means 23, so that the activated activated carbon cartridge 12 is moved. Blowing (cooling air) through the cooling inlet line, the heat factor of the desorbed activated carbon cartridge 12 flowing by the blowing is removed. Through this process, the air by blowing air absorbs heat from the desorbed activated carbon cartridge 12 so that the heat absorbed air flows out through the cooling discharge line 26.

As will be described below, the air discharged through the cooling outflow line 26 is preheated air, and as a result, the required heat source is reduced by recycling it as hot air for desorption. The regenerated activated carbon cartridge 12 that has passed through the cooling chamber 22 is removed from the heat factor and is safe even in the air. The activated carbon adsorption tower 1 may be mounted and used therein.

The flow means 23 flows into and out of the activated carbon cartridge 12 placed in the upper portion by the driving force of the motor 231 into the desorption chamber 21, and then into and out of the cooling chamber 22.

As the air is injected in each chamber), the activated carbon separated from the activated carbon cartridge 12 is deposited. The deposited carbon is discharged to the outside through the activated carbon discharge line to remove foreign substances by oxidation or the like. Will be recycled.

Meanwhile, in the present invention, heat shields 27 and 28 are provided at the first inlet 211 and the first outlet 212 of the desorption chamber 21, the second inlet 221 and the second outlet 222 of the cooling chamber 22. The first inlet 211, the first outlet 212, the second inlet 221, and the second outlet 222 by the activated carbon cartridge 12 flowing by the flow means 23. It is preferable to be configured to open and close.

That is to prevent the heat loss from the desorption chamber 21 and the cooling chamber 22 to the outside by the heat shielding membrane (27, 28). To this end, the thermal barriers 27 and 28 should be made of a material that is both flexible and flame retardant.

The thermal barriers 27 and 28 are upper trains formed at upper ends of each of the first inlet 211 and the first outlet 212, the second inlet 221 and the second outlet 222 of the cooling chamber 22. It is characterized by consisting of a single membrane 27, and a lower heat shielding membrane 28 is formed at the bottom.

The upper heat shield membrane 27 is to be opened and closed by the activated carbon cartridge 12 flowing by the flow means 23, the lower heat shield membrane 28 is in contact with the lower surface of the flow means (23). While maintaining the state is to continue to drive the flow means (23).

To this end, it is preferable that the upper heat shielding membrane 27 has a length longer than that of the lower heat shielding membrane 28 as shown in FIG. 13 to facilitate opening and closing, and the lower heat shielding membrane 28 is the upper heat shielding membrane. Compared with (27), it is preferable to make the number of heat shield sheets to block heat at the lower part of the flow means 23 densely.

More preferably, when the upper heat shielding membrane 27 is mounted on the first inlet 211, the first outlet 212, the second inlet 221, and the second outlet 222, the lower end portion of the activated carbon cartridge 12 is provided. It is reasonable to be configured to contact the upper surface of the flow portion 23 in the flow direction. This is because the thermal barrier 27 has a large area in contact with the upper surface of the flow portion 23 at the first inlet 211, the first outlet 212, the second inlet 221 and the second outlet 222. It is to reduce the loss.

More preferably, as shown in FIG. 14, the upper heat shielding membrane 27 forms a gap in the bracket 271 and includes a plurality of heat shielding sheets 272 attached to the plurality of heat shielding sheets 272. By double the thermal insulation to prevent heat loss.

Thus forming a plurality of heat shield sheet 272, the clearance between the heat shield sheet 272 by the bracket 271 is formed so that the heat shield efficiency between the heat shield sheet 272 to be used as a heat shield space. It is to double. In addition, the heat-dissipating sheet 272 constitutes a weight 273 at a lower end thereof, and after the activated carbon cartridge 12 flows through the heat-dissipating sheet 272, the heat-dissipating sheet 272 is provided with a first inlet 211 and a first outlet ( 212), the speed of closing the second inlet 221 and the second outlet 222 is increased to further reduce heat loss.

More preferably, the heat shield sheet 272 is formed by weaving a yarn mixed with ceramic fiber yarn 272-1 and metal fiber yarn 272-2.

The reason for constructing the heat shield sheet 272 is that the yarn is to achieve heat shielding by using the ceramic fiber yarn (272-1), if the only configuration of the ceramic fiber yarn (272-1) is insufficient ductility The metal fiber yarn 272-2 is mixed.

In other words, the material of the fiber yarn itself is provided with heat shielding and ductility, and in addition, the yarn is formed by weaving so that a plurality of pores are formed, thereby providing the heat shielding structure as the structure of the annual shielding sheet 272. .

As a result, the upper heat shielding membrane 27 shown in FIG. 14 is provided with heat shielding by the gap between the heat shield sheets 272, and the ceramic fiber yarn 272-1 and the metal fiber yarn 272-2 are mixed. By using the yarn, the heat shielding property as well as the ductility is secured, and the heat shielding property is doubled by the formation of pores by the weaving of the yarn. By using the upper heat shielding film 27, the desorption chamber 21 and It is to prevent the heat loss of the cooling chamber 22.

In FIG. 14, an example of the upper thermal barrier layer 27 is illustrated, but in the case of the lower thermal barrier layer 28, as illustrated in FIG. 13, the bracket 281 and the plurality of thermal barrier sheets configured in the bracket 281 ( 282), the structure and the material can be configured in the same bar, the description thereof will be omitted. However, the weight 273 is not formed in the lower heat shield 28 as in the upper heat shield 27.

As mentioned above, the activated carbon cartridge 12, which needs to be regenerated, is passed through the hot air drying device 2 (active carbon regeneration device) so that the activated carbon cartridge 12 is regenerated jointly and continuously. The volatile organic compound desorbed from the desorption and discharge line 25 is discharged.

The paddle 4222 also rotates while the reinforcing rod 4225 and the rotating shaft 4221 located outside thereof are heated between the steam inlet 4223 formed in the steam inlet and the discharge through the steam outlet 4224 formed at the other end. Since the sludge inside the chamber 421 is uniformly stirred and dried, the sludge is transferred toward the sludge outlet 4212.

That is, the steam introduced into the reinforcing rod 4225, which is hollow inside the rotating shaft 4221 through the steam inlet 4223, is introduced into each paddle 4222 to heat the sludge in the chamber 421 to heat and dry the sludge. And condensed steam is discharged to the steam outlet 4224.

As mentioned above, the sewage sludge indirect drying device 42 lowers the water content of the sludge to less than 65%, and the sewage sludge that has passed through the sewage sludge indirect drying device 42 is directly discharged from the sewage sludge 44. ) To be discharged to the solid fuel 45, the embodiment of the sewage sludge direct drying device 44 in the present invention is shown in FIG.

The sewage sludge direct drying device 44 of the present embodiment is to allow the sludge passed through the sewage sludge indirect drying device 42 to the hopper in which the screw conveyor is embedded, the sewage sludge direct drying device 44 at the front end The rotary kiln 441 is installed to be inclined to the rear end and rotates while receiving the driving force of the motor 442, and the rotary shaft 443a installed along the central axis of the rotary kiln 441 from the front end of the rotary kiln 441. A crusher 443b is disposed around the crusher 443 at equal intervals, and a transport bucket 444 attached to the inner circumferential surface of the rotary kiln 441 at equal intervals in a helical shape to convey sludge.

The crusher 443 may be further installed at the rear end of the rotary kiln 441 to increase the crushing efficiency of the sludge. The rotary kiln 441 operates while rotating. The rotary kiln 441 should be installed so as to form a gradient to be lowered from the front end to the rear end so that the sludge can be transported while the rotary kiln 441 is crushed in the crusher 443 therein. A return discharge port 445 is formed at the front end of the rotary kiln 441 in order to return the sludge that has not been transported in the opposite direction to the conveyed direction to the hopper.

The sewage sludge direct drying device 44 configured as described above is to be supplied with hot air generated by the burner 43, so that the sludge is crushed in the device to which the hot air is supplied and dried in a state where the surface area is widened. The sludge introduced at a moisture content of less than 65% in the sludge indirect drying device 42 is dried at a moisture content of less than 10%, thereby allowing the solid fuel 45 to be discharged.
