technical field

The utility model relates to the technical field of environmental protection, in particular to a boiler waste gas treatment device.

Background technique

The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred to simply as boilers, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.

As an important energy conversion equipment, boilers are widely used in industrial and civil heating, bathing or occasions where steam is required. At present, the fuel used in boilers is mainly coal, and the dust and sulfur dioxide produced during the combustion of coal will pollute the environment.
