Energy-saving and environment-friendly furnace

Abstract

The invention provides an energy-saving and environment-friendly furnace which comprises a furnace body, wherein the furnace body is provided with a gas inlet and a gas outlet, and the lower end of the gas inlet is provided with a combustor; and the furnace body is internally provided with a thermocouple which is used for controlling the combustor and connected with the combustor, and the tail end of the furnace body is provided with a catalytic combustion device. The energy-saving and environment-friendly furnace provided by the invention has the beneficial effects that organic solvent waste gas in a drying process is subjected to purification treatment so as to generate large amount of heat, and the heat is sent back to a drying room to recycled, therefore, the pollution problem caused by exhaust emission of the organic solvent is solved and the heat generated by waste-gas burning is fully utilized; and the energy-saving environment-friendly furnace has the advantages of simple structure, low waste gas treatment cost, energy conservation and environmental protection and the like.

Description

technical field [0001] The invention belongs to the field of tinplate printing, and in particular relates to an energy-saving and environment-friendly furnace for treating waste gas generated in the process of tinplate printing. Background technique [0002] In the drying process of the tinplate printing process, there will be volatilization of chemical organic substances. This part of the substance must be discharged from the drying room in time to avoid accumulation of dirt and dust in the drying room, which will affect the quality of printed products. This part is discharged. The gas is a high-temperature gas (temperature is about 160°C-200°C). The traditional method is to discharge it directly into the atmosphere, which not only wastes a lot of heat but also has adverse effects on the environment. Most of the exhausted gas is contained in the solvent of the paint. Organic substances such as hydrocarbons, ketones, and esters can still be burned again to release heat. Co...
