Description

Incinerator for incineration system

The present invention relates to an incineration system for an incineration system, and more particularly, to an incineration system for an incineration system capable of incinerating various domestic wastes supplied from a pretreatment process of the incineration system.

Countries where industrialization is taking place in recent years show a lot of interest in waste treatment and environmental pollution problems due to the increase in industrial waste. Large-scale incineration facilities are being built to treat wastes, but these facilities require a lot of initial installation cost and cost a lot for operation and management.

In order to solve this problem, a relatively small incineration device that can be moved and installed has been proposed.

For example, Korean Patent No. 10-1483751 (registered on January 12, 2015, high-temperature pyrolysis incinerator) describes a small incinerator that can be installed and moved. In particular, a configuration is described in which a blower is configured inside the combustion section, and a plurality of air injection ports are formed in the blower to forcibly introduce external air to increase the combustion efficiency of waste.

The blower is installed on the inner wall surface of the combustion unit, and the air jet port is vertically arranged to enable multi-stage combustion.

However, the prior art describes that multi-stage combustion is possible by forming an air curtain using air injected from the inner wall side of the combustion unit. There is a problem in that combustion efficiency is lowered due to a structural limitation in which multi-stage combustion is difficult.

In addition, since the toxic gas generated during combustion is configured to be exhausted from the combustion chamber as it is, there is a problem in that another environmental pollution problem is mass-produced. That is, the cause of environmental pollution was provided by the harmful components contained in the exhaust gas.
