Abstract

The invention discloses a heating device for recovering industrial waste heat, which belongs to the technical field of industrial waste gas treatment. The cooling pipeline includes a vertically arranged first pipe body, a horizontally arranged second pipe body, a vertically arranged third pipe body, a fourth pipe body and a fifth pipe body, the upper end of the first pipe body passes through the The second pipe body communicates with the upper end of the third pipe body, one end of the fourth pipe body communicates with the first pipe body, and the other end is inclined downward toward the third pipe body; the fifth pipe body One end of the pipe body communicates with the third pipe body, the other end is inclined downward toward the first pipe body, the lower end of the fourth pipe body communicates with the lower end of the fifth pipe body, and the first pipe body 1, the second pipe body and the third pipe body are respectively provided with a plurality of nozzles. The object of the present invention is to provide a heating device for recovering industrial waste heat, which can recover energy from the waste heat of industrial waste gas, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of industrial waste gas treatment, in particular to a heating device for recovering industrial waste heat. Background technique [0002] A large amount of energy is required in industrial production, and boiler combustion is usually required to convert the internal energy into electrical energy output through a series of conversions. Boiler combustion generally uses coal as fuel. The exhaust gas generated by coal combustion contains carbon monoxide, nitrogen monoxide, sulfur dioxide, solid dust and other components, and the high-temperature exhaust gas will further generate harmful substances such as dioxin when it contacts the air, and the exhaust gas is directly discharged Air pollutes the atmosphere. Existing waste gas treatment devices generally pass the waste gas into a scrubber, cool it down and wash it with water, and then discharge it into the atmosphere. However, in the process of cooling the exha...
