Abstract

The invention relates to a boiler flue gas waste heat recovery system which comprises a flue gas channel mounted on a support. A serpentine tube arranged in the flue gas channel is further fixedly mounted on the support. Flue gas removing sheets are mounted between every two adjacent vertical sections of the serpentine tube and arranged in an up-down spaced mode and each flue gas removing sheet comprises two flue gas removing lantern rings arranged on the corresponding vertical sections in a sleeving mode, wherein the flue gas removing lantern rings are provided with filter holes. The flue gas removing sheets are arranged on the serpentine tube of the system in the spaced mode, and the adjacent vertical sections of the serpentine tube are bonded together through the flue gas removing sheets; and the filter holes are formed, the contacting area between the whole system and flue gas is large, and a good flue gas removing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler waste heat recovery device. Background technique [0002] The boiler in the prior art generates a large amount of flue gas inside the boiler, and the flue gas is directly discharged to the outside. Since the flue gas is mixed with some dust, the direct emission affects the environment. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the applicant conducts research and improvement, and provides a boiler flue gas waste heat recovery system. The present invention adopts the following scheme: [0004] A boiler flue gas waste heat recovery system, comprising a flue gas channel installed on a bracket, a serpentine tube placed in the flue gas channel is fixedly installed on the bracket, and two adjacent vertical tubes of the serpentine tube There are smoke removal sheets installed between the sections, and a plurality of s...
