Description

Combustion air aspirator of incinerator

The present invention relates to a combustion air intake device of a one-time batch-type incineration facility, and more particularly, by installing a plurality of auxiliary intakes having an inclined structure and having a smaller inner diameter than the main intakes around the main intakes installed in the opening and closing doors, As the external air flows quickly in the direction of the trash located directly below, it breaks down the trash piles that are burning, and the trash is burned evenly, improving the combustion progress rate and combustion efficiency by more than 30%, and reducing ash generation. It greatly reduced the post-processing work.

As the population grows and the industry develops, the generation of garbage (living garbage, general waste, industrial waste, etc.) is also increasing rapidly, and various pollutions caused by these are becoming social problems, and legal standards are strictly regulated. Treatment methods and methods are constantly being developed and used.

These wastes are disposed of by landfill, reclamation, and incineration, but premodern landfills have limitations due to the absolute shortage of landfills, environmental pollution due to undecomposed waste, odors, and leachate, and extremely recyclable objects. As it is limited, the incineration method that can effectively use waste heat while greatly reducing waste is researched and preferred as the main treatment method.

Looking at the conventional incinerator, the incinerator is installed on the inner side of the incinerator installed on the ground, the incinerator by installing a secondary combustion chamber connected to the combustion chamber and a rear end facility such as an exhaust system, a scrubber, a cyclone on one side thereof. Incineration treatment is performed while inputting an appropriate amount (small amount) of waste into the inlet, and the combustion gas generated during incineration is collected and forcedly discharged to the outside.

In addition, since the air required for combustion is configured to burn garbage by forcibly sucking it from the outside by using the exhaust fan of the dust collector, when the garbage is excessively accumulated or there is a lot of accumulated ash, it is difficult to supply sufficient combustion air as well as incineration. It takes a long time, there is a problem such as unburned and unburned gas is generated, soot or odor / dust is discharged to pollute the surrounding environment.

On the other hand, the 'in one-time incineration type incinerator' has been developed and used to directly improve the incineration efficiency by directly dumping the waste brought into the garbage (or waste) collection vehicle in the combustion chamber (incineration chamber).

The incinerator of the one-time batch input method is installed in the combustion chamber in the form of underground or ring bottom to allow vehicles loaded with garbage to enter (approach) near the combustion chamber, By forming a garbage (waste) inlet of about the same size, and installing an opening and closing door that moves along the horizontal rail (rail) by the opening and closing means in the inlet to dump the waste brought into the garbage (or waste) collection vehicle By injecting the combustion chamber at once and closing the door (top plate) to incinerate, the number of people required for incineration is reduced and the efficiency is greatly improved.

As shown in FIG. 1, the " one-time batch-type incinerator " is provided with a plurality of intake ports 2 having air dampers (intake amount adjusting means) in the opening and closing door 1 at appropriate intervals, and suctioned at the rear end of the combustion chamber 4 The fan 5 is installed, and when the waste (waste) 3 is incinerated, air outside the combustion chamber 4 passes through the intake port 2 by the suction force of the suction fan 5, respectively, and thus the combustion chamber 4 By inflow to the combustion chamber 4, the waste 3 is incinerated.

In addition, the incinerator has no backfire because the air necessary for combustion and the flame generated during the combustion process are introduced into the combustion chamber by the suction fan, and the initial ignition fuel is required during the initial ignition, but the fuel necessary for the incineration after ignition is unnecessary. There is an advantage to save maintenance costs.

In addition, a water cooling chamber in which the cooling water 6 is circulated forcibly is installed inside the opening and closing door 1, and at least one water separator for discharging the cooling water steam generated by the incineration heat (combustion heat) at the upper portion of the opening and closing door 1.水 分離 器) 7 is installed.

The intake openings 2 installed on the opening and closing doors 1 are not only vertically installed, but also have a predetermined height h by the height of the water cooling chamber, and most of the air introduced from the outside during combustion is also sucked vertically.

Therefore, the waste 3 located directly below the intake port 2 is burned intensively, and the waste 3 located between the intake port 2 and the intake port 2 is disposed in the portion directly below the intake port 2. As the combustion (incineration) speed becomes relatively slower, the bone and acid are burned in a continuous wave shape.

In addition, since the air necessary for combustion is sucked vertically along the intake port 2 and then the bending in the direction of the suction fan 5 occurs, an open pupil 8 is generated in a part of the pile of the waste 3 being burned. As a result, incineration is delayed, resulting in uneven combustion.

In addition, the "one-time batch-type incinerator" has a problem in that it is not possible to stir or mix the late garbage because the door cannot be opened during combustion due to the batch-type combustion.

Therefore, there is a problem that not only the combustion time is delayed as a whole, but also a lot of ash is generated by incombustible combustion, and the treatment method with high combustion efficiency is required while proceeding the combustion of waste more uniformly and quickly. .

Therefore, the present invention provides a plurality of auxiliary intakes having an inclined structure while having an inner diameter smaller than the main intakes around the main intakes of the opening / closing doors installed in the one-time incineration facility in the direction of garbage located directly below the main intakes. It aims to improve the combustion progress rate and combustion efficiency by more than 30% by breaking down the waste pile that is being burned as the external air is rapidly introduced, and to make the aftertreatment work easier by greatly reducing the amount of ash generated. do.
