Description

Technical Field

[0001] The utility model relates to an adsorption structure for waste heat recovery equipment for boilers, belonging to the technical field of boiler waste heat flue gas treatment. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. During the operation of the boiler, the flue gas emitted contains a large amount of harmful dust. In order to protect the environment, manufacturers will install and use dust removal devices at the flue gas outlet to remove the dust contained in the flue gas.

[0003] For example, CN218523589U discloses a boiler flue gas treatment device for reducing the content of particulate matter in flue gas. By setting a water collecting tray with a water spraying device inside the treatment box, and a first filter and a second filter fixedly installed on the inner wall of the treatment box above the water collecting tray, the flue gas introduced from the bottom of the treatment box can be washed away by water mist, reducing the presence of particulate matter in the flue gas, and then passing through the first filter and the second filter to double-layer filter, the content of particulate matter in the flue gas can be reduced when discharged by the exhaust fan. However, when using a nozzle to spray water to remove dust from the flue gas, the high-speed flowing flue gas can easily blow away the water mist, making it impossible for the flue gas to fully contact the water mist, and the dispersed water mist is also very easy to adhere to the first filter and the second filter, so that the dust filtered by the first filter and the second filter is agglomerated, and the first filter and the second filter are easily blocked by the agglomerated dust, affecting the filtering effect of the first filter and the second filter.

[0023] Specifically, the guide pipe 4 is in an inverted L shape, and the bottom of the guide pipe 4 extends to the inside of the water tank 6. The bottom of the guide pipe 4 is connected to the air collecting plate 18. A number of exhaust ports 19 are provided under the air collecting plate 18.
