Description

Retrofit incinerator

The present invention relates to incineration of various wastes, and more particularly, to an improved incinerator which completely separates and collects dust and soot generated during combustion of wastes and prevents them from being released into the atmosphere.

Previously, various kinds of wastes (packaging paper, vinyl, styropool, waste tires) generated during industrialization were treated in accordance with landfilling methods.However, landfilling of such industrial wastes causes environmental pollution around landfills and saturation of landfills. Side effects such as provoking caused great social problems.

Incinerators have been actively used as an alternative to industrial wastes in recent years. The treatment of wastes by such incinerators has the positive advantages of less residues from incineration and easier disposal at a relatively low cost. On the other hand, when incineration, waste was not completely burned, and harmful gases, dust, and soot were released into the atmosphere, contaminating the atmosphere.

As proposed in connection with an incinerator for incineration of wastes, Korean Patent Publication No. 95-6314 discloses a base frame having a blower path formed therein so as to pass an intake air of a blower, and communicated with the blower path. An air guide box for guiding the intake air, the combustion chamber casing having a sidewall formed on the sidewall of the intake air guided by the air guide box to cause the vortex in the combustion chamber, and the combustion chamber casing An incinerator has been disclosed as an incinerator configured as an exhaust pipe part which is fastened to the center of the upper end to allow combustion air to be discharged.

That is, such an incinerator, by means of an air passage section consisting of multi-stage air passages drilled at various inclination angles on the side walls of the combustion chamber casing, increases the combustion time and the combustion length, and improves the combustion efficiency through complete combustion, The dust or soot contained in the exhaust air discharged through the exhaust pipe part is intended to be separated and collected as a cyclone dust collector to prevent it from being released into the atmosphere.

However, such a conventional incinerator is insufficient to completely separate the dust discharged from the combustion chamber only by the function of the cyclone dust collector itself, so that dust or soot is discharged along the exhaust air discharged through the exhaust flue of the cyclone dust collector. It has resulted.

More specifically, the exhaust air discharged from the combustion chamber and containing a large amount of dust flows into the cyclone dust collector through the dust discharge pipe and gradually descends, so that dust or soot falls by its own weight and is collected at the bottom of the cyclone dust collector and exhaust air. Is introduced into the lower end of the exhaust flue and discharged to the atmosphere.

At this time, the cyclone dust collector discharges the exhaust air by the natural discharge method according to the air pressure difference between the inside and the outside, so that the exhaust air is not quickly discharged along the exhaust year and is stagnated due to stagnation of the falling dust in the air. By exhausting, the air environment around the incinerator is contaminated by dust or soot discharged along with the exhaust air, which causes a serious problem in which complaints are raised by neighboring residents.

The present invention is configured to expedite only the exhaust air from the combustion chamber and flows into the cyclone dust collector to separate dust or soot, thereby preventing dust or soot from being released into the atmosphere together with the exhaust air, thereby preventing the atmosphere from surrounding the incinerator. It is to provide an improved incinerator that improves the
