Abstract

The invention relates to a waste heat recovery system with a smoke self-removing boiler. The system comprises a smoke channel installed on a support, a coil pipe in the smoke channel is fixedly installed on the support, a straight section of the coil pipe is sleeved with a smoke suction tube, and the side wall of the smoke suction tube is provided with a wall cavity. The side wall of the smoke suction tube is provided with a plurality of arc-shaped protrusion parts which are provided with suction holes, one side located on the straight section of the coil pipe is provided with suction pipes which are communicated with the wall cavity of the smoke suction tube and connected with a dust drawing device. The smoke suction tube is arranged in a spaced mode on the coil pipe, additionally, the arc-shaped protrusions are arranged, the area of contact with dust is increased, and the dust removal effect is improved; in the suction mode, dust remaining around the coil pipe is removed, the dust removal cycle is shortened, and the production cost is lowered.

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 waste heat recovery system for a boiler with self-extracting smoke. The present invention adopts the following scheme: [0004] A boiler waste heat recovery system with self-smoke removal, comprising a flue gas passage installed on a support, a serpentine pipe placed in the flue gas passage is fixedly installed on the support, and the vertical section of the serpentine pipe The upper cover is provided with a smoke and dust s...
