Abstract

The invention provides a method and a device for cooling high-temperature waste gas and recovering waste heat. The method includes that the high-temperature waste gas is in contact with the outer wall of a heat exchange unit barrel via gas flow channels, and heat of the high-temperature waste heat is dissipated, so that the high-temperature gas is cooled; and the heat transmitted via the outer wall of the heat exchange unit barrel is absorbed by heat-conduction media and is transmitted to a metal pipe arranged among the heat-conduction media, water in the metal pipe is heated, and hot water is recycled. By the method, the temperature of exhausted high-temperature industrial waste gas can be effectively and quickly reduced, large quantities of hot water which is a byproduct and is produced after conversion of heat energy can be provided, and effects of energy conservation and emission reduction are realized for enterprises. The device comprises a shell and the heat exchange unit barrel, is simple in structure, good in cooling effect and high in heat recovery efficiency. Daily maintenance for the device is as simple as cleaning for a common ventilating pipeline.

Description

technical field [0001] The invention relates to the field of energy recovery and reuse, in particular to a method and device for cooling high-temperature waste gas and recovering waste heat. Background technique [0002] Waste heat refers to the sensible heat and latent heat that have not been rationally utilized in the original design in the energy-consuming devices of industrial enterprises that have been put into operation due to the limitations of factors such as history, technology, and ideas. It includes waste heat of high-temperature exhaust gas, waste heat of cooling medium, waste heat of waste steam and waste water, waste heat of high-temperature products and slag, waste heat of chemical reaction, waste heat of combustible waste gas and liquid, waste heat, etc. According to the survey, the total waste heat resources of various industries account for about 17% to 67% of their total fuel consumption, and the recyclable waste heat resources are about 60% of the total w...
