AI Technical Summary

Technical Problem

The manufacturing process of the serpentine tubes in existing boilers is complex, which makes it difficult to use the waste heat recovery device on a large scale and has high processing costs.

Method used

The first channel and the second channel design in the main pipe are adopted to realize the convection heat exchange between the flue gas and the cold air through the opening and closing mechanism and the conversion mechanism, and the cooperation of the blocking plate and the cleaning plate is utilized to improve the heat exchange efficiency and perform self-cleaning.

Benefits of technology

The manufacturing process is simplified, the flue gas waste heat recovery efficiency is improved, the processing cost is reduced, and efficient heat exchange and automatic cleaning between flue gas and cold air are achieved.

Abstract

The invention relates to the technical field of heating equipment, in particular to a boiler with a flue gas recovery function, which comprises a main pipe body, the main pipe body is internally provided with a first opening and a second opening, and the first opening and the second opening are respectively formed in a left fixing block and a right fixing block; the first channel and the second channel are both formed in the middle cylinder body, and the first channel and the second channel correspond to the first opening and the second opening respectively; the opening and closing mechanism is used for movably opening the first opening and the second opening; the switching mechanism is used for switching the positions of the first channel and the second channel; flue gas is made to move into the first channel, the first blocking plate is pushed to incline to the maximum blocking angle to block flowing of the flue gas, then the heat exchange efficiency of the flue gas and cold air is improved, the straight-through pipeline is arranged, the movable first blocking plate is arranged in the straight-through pipeline, the flowing speed of the flue gas is blocked, and the heat exchange efficiency of the flue gas and the cold air is improved. The defect that the manufacturing process is complex when a coiled pipe is used is overcome.
