The present invention relates to a odor gas combustion device, and more particularly, to form an explosion prevention port to prevent explosion due to backflow in a combustion device that collects and burns odor gas and recovers the heat discharged from the recovery tank. It is formed to provide an odor gas combustion device to improve the thermal efficiency by recovering the latent heat discharged while preventing the explosion to improve safety.

In general, environmental pollution is a phenomenon that damages the natural environment or living environment due to air, water quality, soil pollution, noise, and vibration generated by human activities. Occurrence of artificial air pollution, water pollution, soil pollution, noise, vibration, ground subsidence, and bad smell caused by various human activities including daily life such as transportation activities such as train, aircraft, ship, etc. It is a phenomenon that damages the natural environment or living environment and ultimately has a detrimental effect on human life and health. This is especially true after the Industrial Revolution, and occurs when human activities exceed the intrinsic self-determination capacity of a given environmental space.

Offensive odor treatment which removes odor generated by gaseous distribution in the air during the above-mentioned environmental pollution refers to a treatment method after reduction or removal of odorous substances or after generation. Countermeasures at the source, direct combustion method, catalytic oxidation method, adsorption method, microorganism deodorization method (biofilter method), condensation method, ozone oxidation method, masking and the like. It is fundamental to replace open generating facilities in a closed manner or to reduce the use or occurrence of odorous substances in a way that eliminates or reduces the source of odors. However, this method may not be applicable to all sources, and countermeasures at the source are to prevent emissions or emissions by retrofitting the device or by improving the working conditions as much as possible.

Looking at the direct combustion of the odor removal method, the odorous substances that cause odors are a lot of organic substances containing sulfur or nitrogen, and most of them are flammable, so when burned at an appropriate temperature, carbon dioxide, water, and other odorous gases are generated. The combustion temperature of the direct combustion method varies depending on the material, but is usually in the range of 680 to 760 ° C, and a contact time of 0.3 to 0.5 seconds is sufficient.

However, insufficient temperature or contact time may not only reduce the removal efficiency but may also cause various aldehydes, ketones, and other unsaturated acids resulting from partial oxidation, resulting in a more odor.

Thus, the odor gas combustion apparatus of the prior art, as shown in Figure 1, the incinerator (1) is installed oven harmful gas inlet pipe (6) and the burner (1a); A purge gas circulation pipe 2 having an inlet / outlet connected to the incinerator 1 and an inlet damper 2a and an intake fan 2b installed at an inlet path; A purge gas discharge pipe (3) branched from the purge gas circulation pipe (2) and provided with a discharge damper (3a) at a branch portion; A heat exchanger (4) installed at an outlet of the purification gas circulation pipe (2); An inlet is connected to the heat exchanger 4, and an outlet is connected to the incinerator 1, and is composed of a fresh air inlet pipe 5 provided with an intake fan 5a.
