Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a boiler with a smoke filtering function. Background Art

[0002] A boiler is an energy conversion device that generates outputs such as steam, high-temperature water or organic heat carriers by burning fuel. In industrial production and people's lives, boilers are widely used to provide thermal energy and convert it into mechanical energy or electrical energy. Most boilers will produce flue gas when burning fuel. If the flue gas is directly discharged into the atmosphere, it will cause air pollution. Therefore, the flue gas needs to be filtered before it can be discharged.

[0003] In order to ensure the efficiency and effect of flue gas filtration, the filter device needs to be cleaned after being used for a period of time. However, the existing boiler flue gas filtration generally requires manual regular cleaning of the filter device, which is tedious and inefficient. In addition, the cleaning requires the filter device to be removed from the boiler, and the flue gas cannot be filtered at this time. Therefore, the boiler cannot be used during this period, and the boiler needs to stop running, which will cause the production line to be interrupted, thereby affecting production efficiency and output.

[0004] In order to solve the technical problem, the utility model proposes a boiler with a smoke filtering function. Utility Model Content
