Description

  The present invention relates to a carbonization treatment apparatus for carbonizing organic matter-containing sludge represented by sewage sludge by dry distillation treatment.

Wastewater containing organic matter discharged from households is generally treated at the sewage treatment facility by the activated sludge method.
Organic sludge is generated with this wastewater treatment, but the amount of organic sludge generated increases year by year as the amount of wastewater treatment increases, and the disposal of such sludge has become a major problem.

When disposing of organic sludge, the organic sludge contains about 99% of water and cannot be disposed as it is, where it is concentrated and dehydrated for weight reduction, or further incinerated or melted. Various processes are currently being applied.
However, if sludge is incinerated or melted, a large amount of energy is consumed, resulting in high processing costs.
Thus, as one method for reducing the amount of organic sludge that consumes less energy, it has been proposed to carbonize the sludge by dry distillation.

  In this carbonization treatment, the sludge contains about 45% by weight of carbon in the substrate. Therefore, the carbon content in the sludge is not consumed as in the incineration and melting treatment, but the sludge is oxygen-free or low. By pyrolysis (carbonization) in an oxygen state, carbon remains, and is produced as a carbide (carbonized product) having a new composition.

FIG. 6 shows an example of a conventional apparatus for that purpose, that is, an apparatus for carbonizing organic substance-containing sludge.
In the figure, reference numeral 200 denotes a receiving hopper, and a sludge cake dehydrated to a moisture content of about 80% is first received by the receiving hopper 200.
The sludge cake received here is sent to the drying furnace 204 by the quantitative supply device 202, where it is dried to a predetermined moisture content, for example, a moisture content of about 40%.

The drying furnace 204 includes a rotating drum as a drying container. The organic substance-containing sludge supplied to the inside from one end side in the axial direction is moved in the axial direction along the inside while rotating the rotating drum. In the process of movement, the sludge is dried by hot air, and the dried sludge is discharged from the other end side in the axial direction.
In the drying furnace 204, the sludge cake is dried and pulverized.

The sludge dried in the drying furnace 204 is subsequently conveyed to the carbonization furnace 208 by the conveyor 206, where the sludge is carbonized by dry distillation.
As shown in FIG. 7, the carbonization furnace 208 is provided with a cylindrical rotary drum 214 as a dry distillation vessel inside the furnace body 210, and the sludge dried in the drying furnace 204 at the previous stage is provided. The conveyor 206 feeds the rotary drum 214 into the rotary drum 214 by a screw feeder (not shown) provided at the position of the front end (left end in the figure) of the rotary drum 214.

The sludge thrown into the rotating drum 214 is first heated by the atmospheric heating inside the external heat chamber 218 by the auxiliary combustion burner (burner for external heat chamber) 216 disposed inside the furnace body 210.
Then, the combustible gas contained in the sludge escapes into the atmosphere of the external heat chamber 218 through the blow pipe 220 provided in the rotating drum 214, and the combustible gas is ignited. Thereafter, the combustible gas is burned. The sludge inside the rotating drum 214 is heated.
At this stage, the auxiliary burner 216 is stopped from burning.

As shown in FIG. 7, an exhaust gas treatment chamber 222 that is partitioned from the external heat chamber 218 is provided inside the furnace body 210, and the exhaust gas from the external heat chamber 218 is guided here.
The exhaust gas treatment chamber 222 is provided with an exhaust gas treatment chamber burner 224, and the unburned gas in the exhaust gas introduced into the exhaust gas treatment chamber 222 is subjected to secondary combustion in the exhaust gas treatment chamber burner 224. .

The sludge inside the rotary drum 214 gradually moves to the right in the figure from the left end in the figure along with the rotation of the rotary drum 214 (the rotary drum 214 has a slight gradient), and finally the carbonization residue (carbonization residue) Product) is discharged from the right end outlet 212 of the rotating drum 214, that is, the carbonization furnace 208.
The carbide (carbonized product) thus obtained has properties close to those of charcoal, and is used for horticultural soils, snow melting agents, and the like.

In FIG. 6, reference numeral 226 denotes a hot air furnace for generating hot air to be supplied to the drying furnace 204, in which the supplied fuel is burned under the supply of combustion air to generate hot air.
Here, LPG is used for the pilot burner, and kerosene is used for the combustion burner.

The hot air generated in the hot air furnace 226 is supplied to the drying furnace 204, further passes through the hot air furnace 226, is collected there through a subsequent dust collector 228, and returned to the hot air furnace 226 again.
That is, the hot air generated in the hot air furnace 226 is circulated and circulated by the circulation fan 232 through the circulation path 230 passing through the drying furnace 204 and the dust collector 228.
In this circulation system, leak air enters the hot air circulating in the drying furnace 204.

  On the other hand, a fixed amount of combustion air is supplied to the hot stove 226, and therefore a branch passage 234 is provided in the downstream portion of the hot stove 226 in order to extract a part of the hot air. A part of is taken out to the outside through this branch 234.

The hot air taken out to the branch passage 234 is in a high temperature state (about 700 ° C.), and the hot air taken out to the branch passage 234 is heat-exchanged by the hot air furnace heat exchanger 236 provided on the circulation passage 230. Further, after being diluted and cooled by the outside air taken in from the air intake port 240, it is discharged from the chimney 246 through the exhaust passages 242 and 244 by the exhaust gas fan 238.
Here, the temperature of the hot air taken out to the branch passage 234 after being heat-exchanged by the hot-air furnace heat exchanger 236 is about 400 ° C., and by dilution / cooling by taking in outside air from the air intake port 240, The temperature is about 200 to 250 ° C. at the downstream portion of the exhaust gas fan 238.

The intake amount of air from the air intake port 240 is adjusted by the adjustment valve 248.
The hot air circulated through the circulation path 230 is heat-exchanged by the hot stove heat exchanger 236, so that the temperature thereof is raised and returned to the inlet of the hot stove 226.

An exhaust passage 250 for discharging the exhaust gas extends from the carbonization furnace 208.
The exhaust gas from the carbonization furnace 208 taken out to the exhaust passage 250 has a high temperature of about 800 to 1000 ° C., where it is first diluted and cooled by taking outside air from the air intake port 258 and then circulated. After heat exchange is performed in the carbonization furnace heat exchanger 252 provided on the passage 230 and the temperature is lowered there, further dilution and re-dilution is performed by taking outside air from the air intake 260 in the downstream portion of the carbonization furnace heat exchanger 252. After being cooled, the exhaust gas fan 254 discharges it from the chimney 246 to the outside through the exhaust passages 256 and 244.

The exhaust gas discharged from the carbonization furnace 208 has a temperature of about 700 ° C. due to dilution and cooling by taking outside air from the air intake 258, and heat exchange in the carbonization furnace heat exchanger 252 and further air intake. The temperature is lowered to a temperature of about 200 to 250 ° C. by cooling by taking in outside air from 260, and then discharged from the chimney 246 through the exhaust passages 256 and 244 by the exhaust gas fan 254.
This carbonization furnace 208 is supplied with fuel such as LPG and kerosene together with combustion air. Here, LPG is used for combustion of the pilot burner, and kerosene is used as fuel for the combustion burner.

This type of carbonization apparatus is disclosed in, for example, Patent Document 1 and Patent Document 2 below.
However, in the case of this carbonization apparatus, the drying furnace 204 and the carbonization furnace 208 are necessary as separate furnaces, and the exhaust gas line and the carbonization furnace 208 for treating exhaust gas discharged from the drying furnace 204 and discharging it from the chimney 246. Exhaust gas lines for processing exhaust gas discharged from the stack and discharging it from the chimney 246 are required as separate exhaust gas lines, increasing the number of equipment in the entire device and increasing the cost of the device, as well as the device itself. The problem of becoming larger in size is included.
