Description

(4) The present invention relates to an apparatus for treating waste containing water, such as sulfuric acid pitch, PCB, and garbage.

Sulfuric acid pitch is produced in large quantities as waste, but it is difficult to dispose of it and the amount is too large.

This also applies to PCBs. In urban areas, disposal of garbage is also a major problem.

By the way, the following equipment, which is not for the purpose of treating waste but directly for reusing organic waste, is commercially available and put to practical use.

The apparatus is as shown in FIG. 2 and is provided with double shutters 101 and 102 at an input port 100, and inputs an object to be processed such as wood chips, paper waste, waste plastic, and the like from the input port 100, and generates negative ions. A reduced-distillation treatment tank 103 to be filled therein and a dry-distilled gas containing smoke in the reduced-distillation treatment tank 103 are introduced, brought into contact with water, emulsified, and condensed by a hydrogen reduction reaction into hydrocarbon oil. And a reduction liquid phase contact treatment device 104. Further, dioxins are decomposed by hydrogen reduction and the action of a neutralizing agent in the reducing liquid phase contact treatment device 104.

(4) Next, the operation of the reduction / distillation tank 103 in the apparatus will be described. The waste put in from the inlet 100 moves downward by its own weight. In the reduction dry distillation tank 103, a carbonized layer 106, a dried layer 107, and an untreated layer 108 are stacked in this order from the lowermost ceramic processing residue 105. Incidentally, reference numeral 109 denotes a processing volume reduction space.

{Circle around (4)} In the reduction / distillation treatment tank 103, a sintering 110, which is an oxidative decomposition reaction without a flame, occurs between the lowermost ceramic processing residue 105 and the upper carbonization tank 106. This oxidative decomposition reaction is performed on the carbide surface, and the oxidized portion is at a temperature of about 800 ° C. to 1000 ° C., which is about red heat, is maintained by the heat storage effect of the ceramic-like residue, and the temperature is further reduced from the contact surface to the carbide by the radiant heat effect. Propagation causes an oxidation reaction, and the heat generated maintains the surface temperature. Further, the oxidation reaction proceeds perpendicular to the surface of the object. The lowermost layer of the ceramic-like processing residue is taken out to the outside when it accumulates to a certain extent, processed into a rust-preventive paint, deodorant / antibacterial fiber, corrugated cardboard, sheet, etc., and reused.

By using such an apparatus, waste can be reused and the waste can be promptly treated, and problems such as dioxin do not occur.

装置 However, since such a device performs the treatment by smoldering, which is an oxidative decomposition reaction that does not involve a flame, the waste that can be treated is limited to one containing almost no water.

Therefore, the inventor of the present invention has proposed a method for treating waste containing water such as sulfuric acid pitch, PCB, garbage and the like that cannot be processed in large quantities by using such a device. The research on whether to do so led to the completion of the present invention. In the case of sulfuric acid pitch, a neutralizing agent (treatment agent) has recently been developed, and if this neutralizing agent (treatment agent) is used, it can be separated into light oil and heavy oil and reused as it is. However, in this case, the configuration is such that processing can be performed only by the present invention without using the processing device.

Therefore, the gist of the present invention is to provide a means for charging waste containing water and a means for charging a processing agent such as a neutralizing agent, and a storage tank for storing the processed material inside, and a storage tank in the middle. While connected to the storage tank via a pipe provided with a valve, it is provided with a means for charging waste containing water and a means for charging a processing agent such as a solidifying agent, and further includes means for stirring and crushing inside. A processing tank provided with a shutter that opens and closes at a predetermined timing on the bottom, connected to the bottom of the processing tank, and provided with a means for sending out the processed material, and a discharge port is provided at an end on the side of the feeding direction. The apparatus for treating waste containing water comprises a transport cylinder provided with a discharge cylinder provided with a shutter that opens and closes at the timing of (1), and a means for drawing out a processed product connected to the discharge cylinder of the transport cylinder. Further, in the above configuration, the charging of the waste containing water and the treatment agent such as the neutralizing agent into the storage tank may be performed by reducing the pressure inside the storage tank with a vacuum pump or the like and suctioning the inside.

Thereby, the sulfuric acid pitch, PCB, etc. are neutralized by the neutralizing agent and solidified to a certain degree of hardness by the solidifying agent, crushed and finely divided, and become a state suitable for processing by the processing apparatus. is there. In the case of garbage, most of the moisture contained in the garbage is discharged by crushing, so that it is possible to put the garbage directly into the processing apparatus for processing. In the case of sulfuric acid pitch, a neutralizing agent (treatment agent) has recently been developed, and if this neutralizing agent (treatment agent) is used, it can be separated into light oil and heavy oil and reused as it is. However, in this case, it is possible to perform processing only by the present invention without using the processing device.

In addition, in the present invention, since there is provided a transport means for transporting the processed material from the processing tank to a predetermined place, the processed material from the processing tank can be directly mechanically sent to the processing apparatus, and Does not need to come into contact with the processed material.

According to the present invention, waste containing water such as sulfuric acid pitch, PCB, garbage and the like which cannot be processed in large quantities can be rapidly processed, which is already commercially available and practically used. The processing can be performed by the processing apparatus which does not cause a problem such as dioxin. In addition to the sulfuric acid pitch, it is possible to treat the sulfuric acid pitch using only the present invention using a neutralizing agent (treatment agent) in addition to the treatment using the treatment device.

The best mode for carrying out the present invention is provided with a means for charging a waste containing water and a means for charging a processing agent such as a neutralizing agent, a storage tank for storing the processed material inside, and a valve in the middle part. While connected to the storage tank through a pipe provided with, a means for inputting waste containing water and a means for inputting a processing agent such as a solidifying agent, and a means for stirring and crushing are further provided inside, A processing tank equipped with a shutter that opens and closes at a predetermined timing on the bottom, connected to the bottom of the processing tank, and provided with a processing object sending-out means inside, and a discharge port at an end on the feeding direction side with a predetermined opening. The present invention is configured to include a transport cylinder provided with a discharge cylinder having a shutter that opens and closes at a timing, and a drawing-out unit for a processing object connected to the discharge cylinder of the transport cylinder.
