Description

Technical Field

[0001] The utility model relates to the technical field of fireplace smoke exhaust, in particular to a dust removal and desulfurization fireplace smoke exhaust device. Background Art

[0002] A fireplace is an indoor heating device that is independent or built into a wall. It uses combustible materials as energy and has a chimney inside. It originated from the heating facilities in Western homes or palaces. Because its fuel is a renewable resource, it has been modernized and improved.

[0003] Publication No. (CN218442368U) discloses a fireplace smoke exhaust device for efficiently removing sulfur and nitrate from flue gas, comprising a fireplace connecting pipe, on which a smoke filter device is installed, and an air outlet of the fireplace connecting pipe is connected to an air inlet of a first suction fan. When the utility model is in use, particles in the flue gas can be filtered through the smoke filter device installed on the fireplace connecting pipe, and the smoke after passing through the smoke filter device enters the interior of a flue gas desulfurization and denitrification device, and the smoke is purified by the smoke desulfurization unit and the smoke denitrification unit of the smoke desulfurization and denitrification device, thereby reducing or eliminating sulfides and nitrates in the smoke.

[0004] The above-mentioned patent does not have the function of cleaning the inside of the connecting pipe. Since a large amount of smoke will be generated due to incomplete combustion when the fireplace is in use, solid particles will be generated in the smoke, which are easy to adhere to the inner wall of the smoke exhaust channel, causing the smoke exhaust channel to be blocked. Users need to clean it manually, which is inconvenient for users. For this reason, we propose a dust removal and desulfurization fireplace smoke exhaust device. Utility Model Content
