Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly combustion, in particular to a high-efficiency, energy-saving, oxygen-enriched combustion-supporting device. Background Art

[0002] The boiler industry is a constantly evolving industry, yet both the industry and its businesses face various challenges. In recent years, with the growing call for low-carbon and environmental protection, the industry's energy-saving boiler concept has necessitated low energy consumption, low pollution, and low emissions. Traditional industrial combustion equipment uses air as the combustion medium, which contains 21% oxygen and 78% nitrogen. During the combustion process, much of the heat generated is used to heat the nitrogen, resulting in low thermal efficiency, high energy consumption, and the emission of numerous air pollutants.

[0003] Chinese patent document CN211822486U discloses a cement kiln oxygen-enriched combustion device, including a device body, a connecting pipe and a mixing pipe, wherein a mixing pipe is fixedly installed on one side of the device body, mounting brackets are fixedly installed at both ends of the mixing pipe, a central axis is fixedly installed between the mounting brackets, a diverter plate is fixedly installed on the outside of the central axis, a cement kiln connecting pipe is fixedly installed on one side of the mixing pipe, an oxygen content detector is fixedly installed on the cement kiln connecting pipe, a connecting pipe is fixedly installed on the other side of the device body, a fan connecting pipe is fixedly connected to one side of the connecting pipe, and the outside of the connection between the connecting pipe and the device body and the fan connecting pipe is fixedly installed. A fixing plate is fixedly installed, and fixing bolts are fixedly installed between the fixing plates. A card groove is provided on the inner side of the connection between the connecting pipe, the device body and the fan connecting pipe. A rubber pad is fixedly installed on the inner side of the card groove. A sealing ring is connected to the inner side of the rubber pad. A first branch pipe is fixedly installed on the outer side of the connecting pipe. A mixing pipe and a diverter plate are fixedly installed on the top of the first branch pipe, the second branch pipe and the third branch pipe. When the equipment is in use, the oxygen is mixed with the gas blown in by the fan through the mixing pipe, and the diverter plate stirs and mixes the flowing gas, so that when the equipment is in use, the oxygen in the gas can be distributed more evenly and the efficiency is higher during use.

[0004] In actual use, although this patent can mix and stir the gas, it cannot control the ratio of the gas. At the same time, only one flame nozzle is provided, which can only burn one side of the fuel, so that the fuel cannot be fully burned, ultimately resulting in fuel waste and the fuel cannot be fully utilized.
