Abstract

The invention belongs to the technical field of heat energy recovery boilers, in particular to an industrial flue gas heat recovery boiler based on spiral spraying. The industrial flue gas heat recovery boiler comprises a boiler shell, a sealing partition plate, a flue gas discharge box, a water tank, a heat insulation layer, a motor, a rotating shaft, a fan, a spiral flue gas pipeline and a wateroutlet pipe. According to the industrial flue gas heat recovery boiler based on spiral spraying, industrial flue gas enters the spiral flue gas pipeline, the temperature of the spiral flue gas pipeline rises, meanwhile, water in the water tank is sprayed out through a water outlet of the water outlet pipe, the sprayed water makes contact with the spiral flue gas pipeline, the water is vaporized,a large amount of water vapor is generated, industrial flue gas heat recovery is achieved, a large amount of energy is saved, and meanwhile, the environmental pollution is reduced; the spiral flue gaspipeline is arranged, so that the contact area between the industrial flue gas and the spiral flue gas pipeline is increased, the contact area between the industrial flue gas and water is increased,the speed of converting the water into the water vapor in unit time is increased, and then the efficiency of converting the water into the water vapor is improved.

Description

technical field [0001] The invention belongs to the technical field of heat energy recovery boilers, in particular to an industrial flue gas heat recovery boiler based on spiral spraying. Background technique [0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. In the part of the combustion equipment, the combustion of the fuel continuously releases heat, and the combustion produces The high-temperature flue gas transfers heat to the heating surface of the boiler through heat transmission, and its temperature gradually decreases, and finally it is discharged from the chimney. [0003] Flue gas is a major way to waste boiler energy. Many of the existing boiler flue gas emissions are directly discharged into the air after simple treatment, so a large amount of heat carried in the...
