Abstract

The invention discloses a rotary waste heat recycling device. The rotary waste heat recycling device comprises a box cover, a heat recovery barrel and a heat insulation box, a rotating shaft fixedly penetrates through the axes of the two ends of the heat recovery barrel, a scale scraping mechanism is installed on the rotating shaft located in the heat recovery barrel, a propeller is connected intoa propeller bin through a bold shaft, a gear used for driving the scale scraping mechanism is installed at the other end of the bold shaft, a cold water inlet is formed in the left end face of a water inlet cavity, and a hot water outlet is rotatably connected to the other end of the rotating shaft. According to the rotary waste heat recycling device, by arranging partition plates, the stroke ofsmoke can be increased, the smoke is used for pushing the heat recovery barrel to rotate, then the staying time of high-temperature smoke is prolonged, the heat recovery barrel can fully absorb heat,and the heat recovery efficiency is improved. The propeller is driven by water flow to drive a gear ring at the other end of the bold shaft, the scale scraping mechanism can be driven to reversely rotate in the heat recovery barrel to wash the inner wall of the heat recovery barrel, scale formation is prevented, and the heat recovery efficiency of the heat recovery barrel can be kept.

Description

technical field [0001] The invention belongs to the technical field of preheat recovery, in particular to a rotary waste heat recovery and utilization device. Background technique [0002] The combustion efficiency of gas-fired boilers is about 90%, and about 10% of the heat enters the environment through the exhaust smoke. Generally, the exhaust gas temperature of gas-fired boilers is generally 120°C to 180°C. The high-temperature flue gas contains a lot of waste heat. Emissions will not only increase the burden on the environment, but also cause a large amount of waste heat in the high-temperature flue gas. Therefore, before the high-temperature flue gas is discharged, structures such as coils are usually used for waste heat recovery treatment, and the high-temperature flue gas is used to contact the coil to heat the medium inside the coil, and water is usually used as the recovery medium to achieve the purpose of heat recovery . [0003] However, the use of coils for wa...
