Description

Multiple Complex Combustion System

The present invention relates to a combustion oxidation system, and more particularly, to a multifunctional combined combustion oxidation system for recycling high temperature waste heat.

Industrial sites generate various kinds of harmful pollutants such as volatile organic compounds (VOCs), and these pollutants cause various environmental problems. The government therefore regulates the removal of harmful components from gases and forced them into the atmosphere. The present invention relates to a combustion oxidation system for treating polluted gases by a method of burning harmful odorous gases and polluted gases to remove harmful components.

The combustion oxidation system by the combustion of such a gas is a device for removing harmful components by introducing contaminated gas into the combustion chamber and ignited and combusted by fuel injected from a fuel injection device provided at one side in the combustion chamber.

Among the combustion oxidation systems, in particular, a heat storage structure is installed inside the chlorine chamber to transfer high heat energy contained in the combustion gas to the heat storage structure to preheat the polluted gas to increase the combustion efficiency of the polluted gas. do.

In general, a regenerative combustion oxidation system includes a combustion chamber for installing a regenerative structure therein and combusting harmful polluting gases together with fuel, and a distributor for supplying harmful gas to the combustion chamber and discharging the combustion gases.

In the prior art for the dispenser, it has been developed to distinguish mainly the drum type dispenser and the disc type dispenser. Disc type distributors are not only large in size but also made of castings to withstand the high temperatures caused by the heat of combustion. Many problems arise in the process of rotating this large distributor. In the case of drum type distributors, the drum may thermally expand due to the high temperature caused by the heat of combustion, which may cause a failure in system operation and cause a fire.

In order to solve the problem caused by the weight of the dispenser, Patent Application No. 2010-41723 attempts to miniaturize the structure of the dispenser by configuring a triple disk type. However, the triple disk type distributor has a complicated structure, which increases manufacturing cost, which hinders practical use. Therefore, it is necessary to develop a combustion oxidation system that has a compact structure and a simplified structure, and Patent No. 918880 proposes a rotary regenerative combustion and oxidation apparatus having a single disk structure to simplify the structure. In the disk structure, the inflow line and the discharge line disposed adjacent to each other, and the purge line are disposed around the pollutant gas such as odor gas passing through the inflow line can be passed to the discharge line, and the odor gas is the combustion gas of the discharge line.

In addition, in the conventional regenerative combustion oxidation system, the polluted gas introduced from the inlet pipe is discharged from the heat storage structure in the combustion chamber to the upper space of the combustion chamber, burned by the torch, and then discharged to the discharge line through the heat storage structure again. There is a problem that the exhaust gas discharged into the regenerated structure is discharged before it is even burned, and needs to be solved.

In addition, in the conventional regenerative combustion oxidation system, the method of recycling the thermal energy of the high-temperature combustion gas generated in the combustion chamber in the system is not specific, causing waste of energy, and thus there is a need to solve this problem.

In addition, the redox system of Regenerative Thermal Oxidizer (RTO) has the advantage of high processing efficiency, but the oxidation treatment is performed at high temperature, which poses potential risks such as fire and explosion. Rotary Wing Type RTO (Rotary Wing Type RTO) configured to rotate the distribution plate often causes internal fire or explosion when the redox system is aimed at removing odor gas.

In order to solve this problem, the present invention is to provide a duct for recovering a part of the combustion gas in the combustion chamber to the inlet pipe in a dual-disk regenerative combustion oxidation system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A is a conceptual diagram schematically illustrating a multifunctional composite combustion oxidation system according to an embodiment of the present invention.

Will pass. The heat storage structure 11 includes heat energy accumulated by the high temperature combustion gas which is burned in the combustion chamber 100 and descends to the heat storage structure 11, thereby preheating the polluted gas coming from the upper distribution unit 25. . The preheated polluted gas is burned together with fuel injected from a torch (including a combustion blower) provided at one side of the combustion chamber 100 in the upper space of the combustion chamber 100.

The combustion oxidation system includes a purge line for supplying purge gas to the combustion chamber 100 in addition to the flow of the exhaust gas (combustion gas) that is combusted with the polluted gas and discharged through the discharge pipe. The purge gas flows into the lower distribution part 23 through the purge pipe 35 and is injected into the combustion chamber through the rotation distribution part 21 and the upper distribution part 25. According to the configuration of the rotary distribution unit 21 of the present invention, the purge gas is ejected into the middle region of the region in which the inlet gas is supplied and the combustion gas discharged from the heat storage structure 11 is discharged. The silver has an inflow-purge-discharge structure as the shaft rotates. Therefore, the region of the heat storage structure through which the inflow gas passes becomes the discharge passage of the combustion gas after being cleaned by the purge gas, so that the area where the inflow gas and the exhaust gas coexist in the heat storage structure does not occur. The detailed configuration of the rotation distribution unit 21 to perform this function will be described in FIGS. 2 and 3.

In addition, the multi-functional complex combustion oxidation system according to an embodiment of the present invention is configured to directly discharge a portion of the combustion gas to the chimney 300 by the hot bypass passage 15 formed on one side of the combustion chamber 100. Therefore, by lowering the temperature and pressure inside the combustion chamber 100, it is possible to prevent the malfunction or explosion of the system due to the temperature and pressure rise. In addition, a damper 61 may be installed to adjust the flow rate of the combustion gas discharged to the chimney 300, and a sensor (not shown) for measuring the temperature and pressure inside the combustion chamber 100. By installing the damper 61 in accordance with the measured value of the sensor can be effectively prevented the malfunction or explosion of the system.

Can be installed. In the regenerative combustion oxidation system such as the present invention in which the pollutant gas flowing into the upper portion of the combustion chamber 100 in the regenerative structure 11 is combusted and flows into the regenerative structure on the opposite side of the central axis, the combustion gas emerges from the regenerative structure near the central axis. Uncontaminated gas can flow back into the heat storage structure. This causes unburned pollutant gases to be discharged along the discharge line, reducing the efficiency of the system. By preventing the partition 17 from protruding from the heat storage structure 11 at the center of the heat storage structure, it is possible to prevent the phenomenon that the introduced polluted gas is discharged immediately without burning.

You can do that. The direction of the inclined wall 13b is an inflow gas from the heat storage structure 11 to the top of the combustion chamber 100 at a hole in which the polluted gas is burned at the top of the combustion chamber 100 and the exhaust gas flows into the heat storage structure 11. Is the direction inclined to the hole (for example, a region) to be introduced. Therefore, it is possible to further prevent the inlet gas from entering the hole (for example, region b) through which the outlet gas is introduced.
