Description

Injection Device for Combustion Auxiliary Catalyst and Waste Incineration System Linked with Burning Temperature The present invention relates to a combustion aid injection device and a combustion temperature-linked incineration system, and more specifically, to a combustion aid injection device and a combustion temperature-linked incineration system that adaptively injects a combustion aid in accordance with the reduction of the combustion temperature that hinders complete combustion in an incinerator. Generally, environmental damage caused by waste inevitably generated alongside industrial growth and modernization is emerging as a key challenge of the times, and as a result, environmental issues are also gaining significant importance. Accordingly, an incineration device is used to incinerate and remove various combustible wastes. As shown in FIG. 1, for example, the incineration device is provided with a main body having an incinerator (1), and an input section (2, 3, 4, 5) for putting waste into is installed on one side. A stocker serving as a grate is provided on the inner bottom of the incinerator (1), and a temperature sensor (12) is installed on the upper part thereof, and an incineration process such as controlling the amount of waste input or combustion air is carried out by a controller (7) according to the detected temperature value. In addition, a waste heat boiler (6) is installed at the rear end of the incinerator to utilize waste heat, and an exhaust gas treatment unit (10) and a chimney (11) are installed to discharge combustion gas. At this time, the incineration device is equipped with a TMS (Tele-Monitoring System) for overall monitoring. However, conventional incineration devices fail to provide a high-temperature environment capable of complete combustion depending on the type of waste or the conditions during incineration, resulting in the generation of harmful substances such as clinker, nitrogen oxides (NOx), and carbon monoxide. Consequently, the operator addresses this by directly injecting combustion improvers into the incinerator, but this method has the problem of being a time-based control system that simply involves repeatedly injecting a fixed amount or manually spraying based on the operator's experience. Figure 1 is a figure showing an incineration device according to the prior art. FIG. 2 is a schematic diagram showing a combustion aid injection device according to the present invention. Figure 3 is a control classification diagram according to temperature of the interlocking controller of the present invention. Figure 4 is a figure showing a combustion temperature-linked incineration system according to the present invention. Hereinafter, a combustion aid injection device and a combustion temperature-linked incineration system according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. First, as shown in FIG. 2, the combustion aid injection device (100) according to the present invention includes a first supply tank (110), a second supply tank (120), an injection tank (130), an injection device (140), and an interlocking controller (150), and preferably further includes a thermal imaging camera (160). The present invention as described above can be connected and installed on one side of an incinerator (200), for example, to be linked with waste incineration in an incinerator (see '200' in FIG. 4). In addition, as another example, some components such as an interlocking controller (150) can be installed in a remote control room. At this time, a first supply tank (110) for storing a combustion improver (first combustion aid) and a second supply tank (120) for storing a calorific value improver (second combustion aid) are each provided, and the injection tank (130) receives the combustion aid to be injected from these. Additionally, the combustion aid injected into the injection tank (130) is supplied into the incinerator through the injection device (140), and the interlocking controller (150) controls selective injection into the incinerator (200) according to the combustion temperature inside the incinerator. Thus, the present invention determines the type and amount of a combustion aid according to the reduction of the combustion temperature that hinders complete combustion in the incinerator (200), and adaptively sprays it. Therefore, by automatically controlling the type and supply of combustion aids according to temperature differences based on temperature data, it is possible to prevent excessive injection, reduce chemical costs, and improve incineration efficiency. More specifically, the first supply tank (110) stores and supplies a first combustion aid that assists in the combustion of waste during incineration in the incinerator (200), and the first combustion aid refers to a 'combustion improver'. The combustion improver induces complete combustion in the waste incinerator (200) and increases
