Energy-saving and environment-friendly desulfurization boiler

Abstract

The invention relates to the technical field of desulfurization boilers, in particular to an energy-saving and environment-friendly desulfurization boiler which comprises a boiler and a desulfurization device, the desulfurization device is arranged on the side of the boiler, and the input end of the desulfurization device communicates with a smoke outlet of the boiler. The desulfurization device further comprises a desulfurization agent spraying device, a filtering smoke guide pipe, a desulfurization stirring device, a water supply device and a desulfurization liquid separation device; one end of the filtering smoke guide pipe is communicated with a smoke outlet of the boiler; the desulfurizing agent spraying device is fixedly installed at the end, away from the boiler, of the filtering smoke guiding pipe. The desulfurization stirring device is fixedly mounted below the desulfurizing agent spraying device, the input end of the desulfurization stirring device is communicated with the output end of the desulfurizing agent spraying device, and the water feeding device is fixedly mounted on the side part of the desulfurization stirring device; the input end of the desulfurization liquid separation device is communicated with the output end of the desulfurization stirring device. The device can effectively purify the sulfurized gas in the flue gas and avoid pollution to the air.

Description

technical field [0001] The invention relates to the technical field of desulfurization boilers, in particular to an energy-saving and environment-friendly desulfurization boiler. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. The hot water or steam generated in the boiler can be directly used for industrial production. It can also be converted into mechanical energy through a steam power plant, or converted into electrical energy through a generator. The boiler that provides hot water is called a hot water boiler. It is mainly used for daily life, and there is also a small amount in industrial production. Application, boilers that generate steam are called steam boilers, often referred to simply as boilers, and are mostly used in thermal power stations, s...

Problems solved by technology

[0003] Some existing domestic stoves and heating boilers need to consume a large amount of coal. During the combustion of coal, a large amount of dust, sulfur dioxide, carbon monoxide, and other harmful substances will be released to pollute the atmosphere. Especially when heating in winter, the polluted area is often filled with smog. It is also a source of pollution that cannot be ignored. The structure of traditional boilers is relatively simple. The high-temperature flue gas from fuel combustion has a very short flow in the boiler, and only part of the heat energy is absorbed, and most of the heat energy is directly discharged to the boiler. in the air

Long-term discharge will cause serious air pollution, so an energy-saving and environmentally friendly desulfurization boiler is needed to solve the above problems
