Description

Multi-layer high temperature pyrolysis incinerator {MULTI LAYER HIGH TEMPERATURE PYROLYSIS INCINERATION APPARATUS}

The present invention relates to a multi-layer high-temperature pyrolysis incineration apparatus, and more specifically, to a multi-layer high-temperature pyrolysis incineration apparatus capable of completely burning and treating various incineration objects ranging from household waste with high moisture content to industrial waste with high calorific value.

In general, as environmental pollution caused by various household wastes and industrial wastes generated at industrial sites intensifies, attempts to prevent secondary pollution by waste and create a pleasant environment are continuously being sought. In light of the increasing trend of the amount, the treatment process for waste is becoming more and more important.

As a result of this, it is common to create a large-scale incineration facility and incinerate the collected waste using fuel. However, such large incineration facilities require enormous initial installation costs and operation and management costs, and problems such as collecting and transporting garbage and disposing of incineration ash arise. In addition, if the proportion of treatment of food waste, animal bones, and special wastes such as fish and shellfish, animal carcasses, etc. is large among the general household wastes, such treated products are accumulated in the lower part of the incinerator, making it difficult to supply oxygen and processing time is reduced. It takes a long time and throughput is quickly reaching its limit.

As a solution to this problem, research and development on an industrial waste treatment device capable of moving and installing are attracting attention.

Korean Patent Registration No. 10-1604837 "Multi-layer high-temperature pyrolysis incinerator" (registered on March 14, 2016), Korean Patent No. 10-1709744 "High-temperature pyrolysis incineration device" (registered on February 17, 2017), etc. Provides a multi-layered high-temperature pyrolysis incineration device that completely burns the treated product at a high temperature by forcibly blowing into the interior to multilayer the combustion layer of the incinerator, and prevents incomplete combustion of the treated product so that the emission of environmentally harmful substances and soot can be blocked. have.

Such conventional techniques include forming a multi-layered air curtain inside the incinerator to form a multi-layered combustion chamber in the vertical direction, by forming a blower unit on the inner wall of the incinerator to inject air radially inward, or A central air injection pipe is further provided on the upper part of the stirring device disposed in the center of the unit to inject air toward the outer side in the radial direction.

Such a structure is a step forward in that it forms a multi-layered air curtain, but incomplete combustion occurs because oxygen is not supplied smoothly to the lower part of the incineration chamber, and incineration targets that have not been completely burned are accumulated in the lower part of the incineration chamber. Occurs.

In addition, in the incineration apparatus according to the prior art, since the position of the burner for burning the object to be incinerated is fixed on one side of the incineration chamber, there is a problem that the temperature inside the incineration chamber is not uniform and the object to be incinerated is not burned evenly.

In order to solve such a problem, a method of arranging a stirrer for stirring the object to be incinerated inside the incineration apparatus may be proposed. However, since the high moisture content and heavy incineration targets are easily entangled with the stirrer while being accumulated in the lower part of the incineration chamber, smooth stirring is not achieved. In addition, it is very inconvenient to discharge the incineration ash to the outside of the incinerator due to the stirrer added inside the incinerator.

In addition, since the stirrer of the incineration apparatus according to the prior art has only the effect of mixing the incineration object in the vertical direction in place, it is difficult to completely and evenly burn the injected incineration object.

In addition, in the conventional incineration apparatus, since the burned incineration ash and the object to be incinerated are not separated and burned together, there is a problem in that combustion efficiency is greatly deteriorated, such as a very long incineration time and an increase in fuel consumption.

At this time, the first auxiliary air discharge hole 233 of the rotary rod 230 and the second auxiliary air discharge hole 213 of the rotary plate rotary shaft 210 are provided to supply air for completely burning the residue mixed in the incineration ash. do.

In addition, the first scraper 240 and the second scraper 250 push the incineration material into the incineration material discharge hole 141 according to the rotation of the rotating rod 230 so that the incineration material is discharged into the incineration material container 143.

That is, the first scraper 240 and the second scraper 250 agitate the residue remaining in the incinerator so that the residue is completely burned, and in addition, the incinerator is collected and discharged into the incinerator discharge hole 141. will be.

A state in which the incineration ash of the object to be incinerated is discharged into the incineration ash discharge hole 141 by the first scraper 240 and the second scraper 250 can be seen in FIG. 6.

6 shows a state in which the incineration ash is pushed and moved by the first and second scrapers 440 and 450 so that the incineration ash is discharged into the incineration ash discharge hole 141, and the residue in the incineration ash is also stirred inside and outside in this manner.

In FIG. 7, it can be seen that the incineration ash collected in the incineration ash discharge hole 141 is discharged through the incineration ash discharge hole 141.

When the incineration ash discharge hole switch 142 of the incineration ash discharge unit 140 is operated and the incineration ash discharge unit 140 is opened as shown in FIG. It falls into the incineration ash container 143 through 141 and is collected in the incineration ash container 143. The incineration ash of the object to be incinerated collected in the incineration ash container 143 is discharged to the outside by an incineration ash suction and discharger (not shown) as mentioned above.
