Description

Swirl-type plasma combustion reactor and combustion system of cement kiln using same

The present invention relates to a swirl flow type plasma combustion reactor for burning waste using thermal plasma.

Various proposals are known to incinerate wastes such as biomass and waste plastics or to use them as raw materials for gasification. Among them, the gasification method using waste plastics (waste synthetic resin, waste vinyl, waste fibers, PT bottles, etc.) development is taking place. Although the temperature of the plasma generated from the plasma generator varies greatly inside and outside the flame, the temperature of the arc is estimated to be about 10,000 to 20,000K, and the external temperature is estimated to be about 2000 to 3000K. Using these characteristics of plasma, by maintaining the combustion reactor at a high temperature of 1200 ° C or higher, thermal decomposition occurs to form syngas in this temperature range, and by suppressing the emission of secondary pollutants having characteristics that are suppressed or decomposed at high temperatures. Development of a process for reducing environmental pollution is being attempted.

The plasma combustion process of waste plastics using a plasma combustion reactor has the advantage of obtaining a fast thermal decomposition rate and efficiency, and the residue after incineration can be vitrified and treated stably. It is known to be advantageous for waste treatment and fuel source security because it can be operated. Regarding the technology of pyrolyzing waste through plasma, Korean Patent Laid-Open No. 10-2008-0045574 proposes a process and apparatus for purifying syngas from waste using plasma pyrolysis process technology. In addition, Korean Patent Laid-Open No. 10-2012-0033682 discloses a device for pyrolysis of waste polymer insulation, a plasma device connected to the pyrolysis device to supply plasma to the pyrolysis gas generated in the pyrolysis device, and gasification of the pyrolysis gas connected to the plasma device A gasification reactor in which the reaction takes place, a cooling device of a reactor, and the like have been proposed.

However, in the existing plasma combustion reactor, despite the high temperature in the reactor, the high temperature residence time of the alternative fuel is short and structurally, a dead zone is generated, so that wastes may be accumulated without being burned, and during combustion. Due to the dispersion of waste and the external air at room temperature supplied for combustion air, the temperature in the reactor may drop, and the amount of tar generated may be rapidly increased. Existing technologies that use plasma to burn and incinerate or gasify waste have limitations in suppressing the generation of secondary hazardous substances in the case of incineration, and require additional costs due to burying of hazardous substances, decrease energy recovery efficiency, and burden the environment. has not been able to solve the problem of In addition, even in the case of gasification of waste, the problem of complicated processes and reduced efficiency, the emission of environmental pollutants and the additional burden of new construction costs due to large-capacity facilities, and the high cost of maintenance cannot be solved.
